FIELD OF THE DISCLOSURE
[0002] The disclosure relates to configuring and using geographical
zones. In particular, it relates to systems and methods to remotely
control and monitor movable entities' functions and positioning
data in relation to pre-configured geographical zones.
BACKGROUND OF THE DISCLOSURE
[0003] Vehicle tracking systems have become increasingly popular
and more economically accessible to businesses and individuals.
Most tracking locator systems utilize ground positioning system
(GPS) technology. GPS vehicle tracking systems have diverse
applications such as cargo transportation, public transportation,
personal tracking, investigations of enforcement agencies, and
others.
[0004] In fleet management, GPS vehicle tracking systems allow
increasing fleet efficiency, reducing operating costs such as fuel
costs, and supervising the correct operation of deliveries,
pick-ups, and routes associated with fleet operation.
[0005] In personal tracking, individuals use GPS vehicle tracking
information to obtain the shortest or fastest path to a
destination, their current location in relation to another
location, etc. Furthermore, personal tracking systems allow users
to track vehicles that have been entrusted to another person.
Likewise, enforcement agencies may use GPS vehicle tracking systems
to locate patrol vehicles as well as to recover stolen
vehicles.
[0006] While current GPS vehicle tracking systems provide benefits
such as increased productivity and safety, these benefits are yet
to be maximized. Current systems are limited to relaying the GPS
information to a control center or a web server and plotting the
position of the vehicle on a computer map.
SUMMARY OF THE DISCLOSURE
[0007] The present disclosure provides a system and method that
allows a user to control and monitor vehicles and other moving
entities by using preconfigured geographical zones.
[0008] In one aspect, there is a method to define a geographical
zone utilized to regulate a movable entity that has an attached
transponder. The method comprises loading from a computing device
to a memory in a transponder a plurality of coordinates, mapping
the coordinates on a pixilated image so as to assign one pixel to
each coordinate of the plurality of coordinates, wherein the
distance between each assigned pixel is configurable, connecting
the plurality of assigned pixels with lines forming a contiguous
and connected line that encloses an area in the pixilated image,
and activating the pixels that lie on the lines in order to form a
contiguous array of pixels that enclose a shape in the pixilated
image. In another aspect, the method to define a geographical zone
allows to regulate the entity by monitoring, controlling and
visualizing the status of the entity. The status of the entity may
be movement, non-movement, and position of the entity. The movable
entity being controlled and monitored depending on the location of
the movable entity relative to said geographical zone.
[0009] In another aspect, the plurality of coordinates are entered
by a user of a computer device and transmitted to the transponder.
The user is allowed to enter geographical coordinates by allowing a
user to select points in a map in a computer by clicking on the map
and calculating the geographical coordinates of each selected point
in the map. In another aspect, the user is allowed to enter
geographical coordinates by typing on the computer the longitude
and latitude. The plurality of geographical coordinates is defined
either by the Mercator system or by a latitude and longitude
system.
[0010] In yet another aspect, the position of the entity in
relation to the geographical zone as described in the method to
define a geographical zone is determined by the steps of locating
the transponder within the pixilated image by activating a pixel
corresponding to the geographical coordinates where the transponder
is located, extending two vertical lines in opposite directions and
originating from the pixel, extending two horizontal lines in
opposite directions and originating from the pixel, determining the
number of times each line crosses the boundary of the geographical
zone, assigning an outside status to each line that crosses the
boundary an even number of times, assigning an inside status to
each line that crosses the boundary an odd number of times, and
identifying the transponder as being inside the boundary if the
status of three out of four lines indicate an inside status.
[0011] In another aspect, the transponder has a ground positioning
system receiver that calculates the transponder coordinates, and
allows it to identify the location of the entity in the pixilated
image as one pixel in the computer image.
[0012] In another aspect, the geographical area is a geometrical
shape such as a square, rectangle, triangle, circle, oval, or
trapezoid. The shape of the geographical area can also be the shape
of a non-geometrical shape such as the shape of the border
delimiting a street route, a state, a city, a county, or a
country.
[0013] In one aspect, there is a method to define a geographical
zone utilized to regulate a movable entity having an attached
transponder. The method comprises allowing a user to enter a
plurality of waypoints, each waypoint in the plurality of waypoints
being defined by a geographical coordinate and a radius; wherein
the geographical coordinate is represented by a latitude and
longitude, and the radius is represented by a distance magnitude;
and loading plurality of waypoints on a transponder.
[0014] In another aspect, the transponder can determine whether the
transponder is inside or outside the geographical zone by obtaining
global positioning coordinates, and calculating whether the global
positioning coordinates are inside at least one waypoint of the
plurality of waypoints. The shape of the geographical area is the
shape of a non-geometrical shape.
[0015] In another aspect, all waypoints in the plurality of
waypoints have the same coordinate but different radii, such that
all the waypoints in the plurality of waypoints are concentric.
[0016] In one aspect, there is a method to identify a geographical
area for regulating an entity. The method comprises allowing a user
to identify a geometrical area in a computer map, the geometrical
area using two coordinate attributes, dividing the identified
geometrical area into a grid, allowing a user to select at least
one section from within the grid in order to define a geographical
area, associating the at least one section to a pixel in a
pixilated computer image such that the pixels selected by the user
in the identified geometrical area are identified as being in the
geographical area; and loading the pixilated computer image to a
memory in a transponder.
[0017] In another aspect, the pixilated computer image has a
directly proportional number of columns and rows as the identified
geometrical area. Alternatively, the pixilated computer image has
the same number of columns and rows as the identified geometrical
area. In another aspect, the geometrical area is rectangular or
circular. In yet another aspect, a second geographical area is
defined by a plurality of geographical areas.
[0018] In yet another aspect, the entity having attached the
transponder may be located in the geographical area by obtaining a
position of the transponder from a ground positioning unit operably
connected to the transponder, correlating the position of the
transponder in the geographical area to a representative position
of the transponder in the pixilated computer image, and determining
whether the representative position of the transponder in the
pixilated computer image falls on a pixel that is flagged as being
in the geographical area.

DETAILED DESCRIPTION
[0048] Asset management and monitoring devices that use
ground-positioning systems allow users to track the position of
vehicles and cargo and other entities. The method and system
described below utilizes a transponder that communicates over
cellular and satellite communication networks in combination with
GPS positioning satellites capable of providing position and status
information on a global scale. The transponder allows interaction
with and control of a wide range of peripheral devices, including
operating according to preconfigured geographical zones and
events.
[0049] A transponder can be mounted, attached, manufactured, or
otherwise included upon/in various articles or entities. Such
articles or entities may include vehicles, aircraft, cargo,
persons, animals, or any other item where tracking its movement
and/or location is beneficial. Within the context of the tracking
system, the transponder works to collect, process, and communicate
information about the article or entity to which the transponder is
attached. Furthermore, when requested, the transponder can issue
various commands and instructions to the local article or
entity.
[0050] The transponder has the features, flexibility, and
capability of an intelligent device. The transponder contains an at
least 32-bit processor that can interface with at least one modem
(cellular, satellite, and others), at least one Global Positioning
System (GPS) receiver, at least one memory module, and other
peripheral devices. Other components of the transponder may
include, but are not limited is at least one GPS antenna, at least
one modem antenna, at least one serial port for communication and
configuration, at least one multiple connector pin, which contains
at least one input and at least one output. These inputs and
outputs are configurable to be associated with a configurable event
or configurable operation.
[0051] The transponder can include many different combinations of
the components listed above and similar components. For example, a
transponder may have two modems wherein one modem is a satellite
modem and one modem is a cellular modem. Additionally, a
transponder could also contain a Bluetooth receiver in combination
with the other components. The components of the transponder depend
upon which capabilities the user requires.
[0052] Among its many capabilities, the central processing unit of
the transponder can be configured to manage configurable events or
configurable operations. Managing events means that among other
capabilities, the transponder can report, observe, recognize,
process, and analyze numerous configurable events or configurable
operations, give and respond to various commands, effectuate
numerous events in its local installation, and contain a history
recording component.
[0053] The event message triggered by physical and logical events
include the event message itself and such information includes
latitude, longitude, speed, direction, time, state of all the
inputs, state of all outputs, odometer, event reason or source, and
any other relevant information concerning the entity.
[0054] The transponder is configurable to include as few or as many
configurable logical events or physical events as the user desires.
Events may be physical or logical. Logical events may be based on
rules using a combination of the GPS position and one other factor
such as time or speed. However, logical events can be based upon a
combination of factors. Physical events are those events that are
physically manifested in the vehicle or object.
[0055] Configurable events or configurable operations refer to
those actions that the CPU in the transponder will execute.
Configurable events or configurable operations include, but are not
limited to, the turning on or off of an ignition to a vehicle; the
temperature level or change thereof; the fuel tank level or change
thereof; the pressing of a button or level within a vehicle,
wherein the button is associated with an emergency event; locking
or unlocking of a door or latch, the opening or closing of a
window, turning on or off of an LED signal light, the turning or
off of various relays, the turning on or off of an alarm; the
change of the power level of the battery; a bar code scanned by a
connected scanner; passenger loading or unloading; cargo loading or
unloading; vehicle part malfunction; vehicle diagnostics code
received; impact detected; airbag deployed; seatbelts
latched/unlatched; tire air pressure high/low; and other mechanisms
in the vehicle or object.
[0056] Other configurable events or configurable operations include
the location of the vehicle or object in terms of latitude,
longitude, and/or altitude; the time and corresponding location of
the last configurable event reported; the speed and direction of
the vehicle or object, the state of any assigned inputs or outputs
or change thereof; a pre-selected distance; a pre-selected time
interval; pre-selected intervals based upon date and time
reference; a pre-selected schedule for reporting and recording any
of the configurable events or configurable operations; a
pre-selected maximum speed; maximum acceleration; length of idle
for a vehicle; length of non movement for an object.
[0057] Additional configurable events or configurable operations
include the entering or exiting of a pre-set waypoint or a pre-set
zone. A waypoint is a circular area defined by a geographical
center point and radius. The area defined by the waypoint is
configurable by changing the radius and the position of the
geographical center point. A zone is an irregular region defined by
a series of line segments enclosing an area.
[0058] The configurable events or configurable operations or
combinations thereof can be processed in order to transmit a
specific message, respond to a specific query or command, enable or
disable a specific mechanism, or recognize a specific event. For
example, the CPU can be configured to process that, if at a
pre-selected time, the vehicle or object has not moved a
pre-selected distance, then the transponder is sent a command to
turn off the ignition of the vehicle or otherwise alter the
article.
[0059] The configurable events or configurable operations occur in
many situations. These situations include, but are not limited to
where configurable events or configurable operations occur in
response to a command; where configurable events or configurable
operations occur in response to a query, or where configurable or
configurable operations events occur upon recognition of
pre-selected conditions.
[0060] Configurable boundaries or geographical zones can also be
used and are configurable to any shape the user desires. For
example, the boundary or zone can trace the border of a state line
or trace the route of a selected highway or path. The boundary or
zone can trace the border of the premises of a school zone, a
no-fly zone, a city, etc. The boundary or zone can also be a
geometric shape or non-geometric shape. A further benefit of the
present disclosure is that the transponder can be updated and
configured locally or over-the-air.
[0061] FIG. 1A illustrates the high-level architecture of a
computer system for controlling and monitoring vehicles. A
plurality of vehicles 110 has at least one transponder 105 that can
be tracked and allows the functionality to control remotely
functionality of the vehicle 115.
[0062] The transponder 105 connects with a plurality and any
combination of communication networks. In one embodiment, such
communications network is a cellular network including multiple
cellular base stations 120 and service providers 135. In another
embodiment, such communications network is a cellular network
including multiple cellular base stations with SMS receivers 125
and service providers 140. In another embodiment, such
communications network is a satellite network including multiple
satellite receivers and transmitters 130 and satellite ground
stations 145. In yet another embodiment, such communications
network is a short radio communications network.
[0063] The communications network permits the transponder 105 to
communicate with a backend control system 150. The transponder 105
sends event information to backend control system 150 and responds
to commands sent to the transponder 105 by the backend control
system 150 through the communications network. The backend control
system 150 includes a plurality of gateways 151, 152, 153 and 154
which interact with a codec 155. The codec 155 is the central
codifier and decodifier of the backend control system 150 and
allows the backend control system to adapt and communicate with any
communications network. The modular design enables the introduction
of new hardware and network protocols without having to change
monitoring and reporting software. The backend control system 150
also includes an asynchronous routing system 159 that allows
incoming and outgoing communications to be handled asynchronously
and efficiently. In one embodiment, the asynchronous routing system
159 includes a plurality of routing services 156, at least one
database 157 and a web server 158. The messages routed by the
routing services 156 are directly communicated to a client console
176. The client console 176 presents vehicle 115 and transponder
105 information to the operator. The client console 176 sends
commands to the transponder 105 through the backend control system
150 and a communications network.
[0064] Multiple applications may connect to the central database
157 to provide further system functionality. An administrator
console 175 permits operators to add, edit or delete transponder
105 information, vehicle 115 information, user information, etc. A
history processor console 174 allows an operator to view reports
and replay event data. An operations data processor 173 permits an
operator to define geographical zones and waypoints for operation
of the transponder 105. A configuration utility 172 permits
operators to configure easily transponder 105 features and
functionality.
[0065] Vehicle information can be presented to the operator through
alternative media besides a client console 176. In one embodiment,
vehicle information can be presented to an operator through a
website or an email by transmitting such information from a web
server 158 to a web client 171. In another embodiment, vehicle
information can be presented to the operator by sending a text or
voice messages to a predetermined wireless device 180.
[0066] FIG. 1B illustrates the wireless connectivity of the
transponder 105. The transponder 105 receives radio signals from a
GPS constellation 131 allowing the transponder 105 to process
positioning information. The transponder 105 can communicate
wirelessly to various networks through multiple wireless devices
integrated in the transponder's 105 hardware such as a short range
radio 154, a cellular receiver 120 and 125, and a satellite
130.
[0067] Transponder Hardware Configuration
[0068] FIG. 2 illustrates the internal board 240 of the transponder
105. The transponder board 240 contains at least one GPS receiver
215, at least one CPU 210, at least one cellular modem 220, and at
least one memory module 280. At least one Bluetooth receiver can be
included in the internal board 240. In one embodiment, the tracking
system uses utilizes both cellular and satellite networks to
provide the most affordable and complete global coverage.
[0069] The global positioning (GPS) receiver 215 is a capable of
positioning accuracy to within a few feet or less. For example, a
12-Channel Trimble SQ, Lapaic UV40, or small-range accurate
receivers are contemplated.
[0070] The processor 210 is at least a 32-bit processor. The
processor 210 includes at least 32 Kilo-bytes of RAM. For example,
a Motorola MMC2114 32-Bit RISC processor with two built-in UARTs is
contemplated. However, a similar or more advanced processor is also
contemplated. The memory module 280 includes at least two
additional memory chips, wherein each additional memory chip is at
least 128K.
[0071] In one embodiment, the cellular receiver or cellular modem
220 is the primary means for communication. The cellular modem 220
interfaces with at least one on board processor 110's built-in
serial ports 345 or 340 as illustrated in FIG. 3B. The cellular
modem 220 may be a GSM, CDMA or similar modem. The satellite modem
or transceiver 230 is external to the transponder 105 and is
connected by a serial port 340. In one embodiment, the satellite
modem 230 is located under fiberglass or any other non-metal
material in order to provide maximum coverage. The satellite modem
230 is primarily used only when there is little or no cellular
coverage or when the user specifies use of the satellite modem 230.
The efficient use of the satellite modem 230 functions to lower the
cost of the tracking system to the user. One embodiment
contemplates a satellite modem 230 such as a Sky Wave DMR-200
satellite modem. Similar contemplated satellite modems include
features such as a built-in omni-directional antenna, provide
worldwide coverage, and efficiently interfaces with the
transponder's processor 210.
[0072] The Bluetooth receiver 215 has a range of at least 20
meters. For example, in one embodiment, a National Semiconductor
Simply Blue LMX9820 Class 2 Bluetooth module is contemplated.
However, similar or more advanced Bluetooth receivers are
contemplated as is any other radio connectivity that does not
require a line of sight. Preferably, the Bluetooth receiver 215 is
installed to utilize different capabilities such as integrating and
supporting multiple wireless peripherals, acting as a short-range
radio to download data, or to serve as a local, traveling wireless
"hotspot."
[0073] In one embodiment, the power source 135, is a fused main
power-in source with a recommended operating voltage range between
12 and 24 volts. One embodiment contemplates low power consumption
(65 mA or less) during normal operation. Furthermore, the
transponder 105 includes a circuitry for charging an optional
backup battery. If the primary power source 135 supply reaches a
minimum acceptable voltage, the transponder 105 will automatically
switch to backup power as well as transmitting a message
identifying that the power source 135 is a critical level.
[0074] The transponder 105 is a small and affordable unit with
numerous features. The external view of the transponder is
illustrated in FIGS. 3A and 3B. In one embodiment, the housing 335
of the transponder 105 is metal or made from a material that
functions to protect the inner components from external events such
as physical damage, dust, water, excessive temperatures or any
other event that could affect the integrity of the transponder. As
illustrated in FIGS. 3A, 3B, and 3C, the transponder 105 contains
at least two external communication ports 305 and 340, a multiple
pin connector 345 with at least nine sensor inputs 350, at least
four control outputs 355, a modem antenna connector 300, several
indicators 315, 320, 325, 330, and a GPS antenna connector 310. In
another embodiment, a Bluetooth antenna (not depicted) is an
optional feature.
[0075] The multiple pin connection 345 of one embodiment contains
20 pins. The number of pins within the transponder 105 is variable
ranging from zero to as many pins as appropriate for its intended
use.
[0076] At least nine of the pins function as inputs 345. The inputs
345 function to gather information concerning the status of the
article upon which the transponder 105 is mounted. Each input can
be assigned to a corresponding specific configurable event or
operation. The input signal may be analog or digital. In one
embodiment, each input 345 is optically isolated and protected
against over-voltage/under-voltage current surges. Furthermore,
each input 345 can be individually enabled or disabled either
locally via a serial cable or over the air. Additionally, each
input 345 is configurable over the air and locally. These inputs
345 are configurable to the specific desires and uses of the user.
These capabilities are later discussed in further detail.
[0077] In one embodiment, at least one input 345 is a digital input
dedicated to the ignition circuit path of a vehicle. If the input
345 is enabled, a message is transmitted when the vehicle is turned
on. A second message is transmitted when the vehicle is turned off.
Analog inputs are also useful in functioning with ranges. For
example, an analog input can function with temperature and fuel
tank levels. In one embodiment, the remaining inputs function to
monitor different features of the vehicle.
[0078] Other inputs 345 may include a panic input, which may be
connected to an emergency button installed discreetly inside the
vehicle. If the panic input is enabled and the emergency button is
pressed for a pre-selected, configurable amount of time, a message
is transmitted relating the panic event. Similar inputs may include
a medical assistance input, roadside assistance input or any other
inputs, which the operator may use for immediately communicating an
event. These messages can be continually transmitted for a
determined period of time until the message is acknowledged by the
proper party or monitoring entity.
[0079] At least four of the pins in the pin connector 345 function
as outputs 355. The outputs 355 function to control mechanisms or
enact functions upon the article or vehicle where the transponder
105 is mounted. Each output 355 is fused and capable of providing
at least 0.5 amps per channel. However, if more than one output 355
channel is utilized the sum total of all used output channels
should not exceed one amp. Each output 355 can be set high or low
utilizing an over-the-air command. In one embodiment, the outputs
355 control various apparatus and objects within the vehicle
itself. For example purposes only, the outputs can control the door
locks, the vehicle windows, a LED signal light, the fuel tanks or
valves, various relays, and other mechanisms in the vehicle. The
LED signal light can function as an acknowledgement tool. For
example, in the case of medical, roadside, or safety assistance is
needed, the occupier or passenger of the vehicle can press a button
to alert the client console 176. When the operator or appropriate
entity receives and acknowledges the event, a command is sent back
to the transponder 105 that will turn on an intermittent light for
a determined amount of time so that the occupier or passenger is
assured the message was received and assistance is on the way. In
other embodiments, such as a cargo, the outputs 355 can control
various features of the cargo such as a locking mechanism, a signal
light, or temperature control.
[0080] The serial ports 305 and 340 in FIGS. 3A and 3B illustrate
at least one 9-pin serial port 340 for the purpose of interacting
with and controlling peripheral devices and at least one 4-pin
serial interface 305 consisting of data in/out and two flow control
lines. The external serial port 340 can support various peripheral
devices such as a MDT (mobile data terminal), satellite modem, bar
code scanner, short-range radio, or PDA. For example, the external
serial port 340 can support a passenger counter which interfaces
several door infrared motion sensors for the purpose of the
counting the number of people entering or exiting from the one to
four doors. The serial port 305 can also be used to test and
configure applications within the transponder 105. In one
embodiment, the port 305 functions as a programming port that is
used when programming the unit for the first time or re-programming
the unit's core program.
[0081] The indicators 330, 325, 320, 315 in FIG. 3A can be
associated with any type of connection, signal, power level,
status, and any other similar communications. In one embodiment and
in FIG. 3A, indicator 330 is an LED that appears red when the
transponder has power connected to it. Indicator 325 is an LED that
blinks green at a rapid pace when the GPS receiver is establishing
a connection and slowly blinks green when a connection is
established. Indicator 320 is an LED light that blinks green for
every message received and red for every message sent. Finally,
indicator 315 is an LED that is red when the cellular modem is
roaming and is green when it is at home.
[0082] Transponder Firmware Configuration
[0083] The transponder 105 has numerous features, functions, and
capabilities described below. The transponder 105 is an intelligent
device controlled by an at least 32-bit processor 110. FIG. 2
depicts one embodiment where the processor 105 has the capability
to interface with a GPS receiver 215, a cellular modem 220, a
Bluetooth modem 225, a memory module 280, and a satellite modem
230.
[0084] The transponder 105 can be configured to report, observe,
and analyze numerous logical events. The transponder is also
configurable to give and respond to various commands, and contains
a configurable history-recording component. A further benefit of
the present disclosure is that all the configurations to the
transponder 105 can be done locally or over-the-air. Thus, the user
is able to configure any features including the entire operating
system of the transponder over the air. This over-the-air
configuration can be accomplished through use of the cellular modem
200, the Bluetooth modem 225, or any other wireless means.
[0085] Moreover, the transponder 105 can be configured locally
through connecting to a serial port 305 or 340. Another benefit of
the present disclosure is that during over-the-air or local
configuration, the transponder 105 continues to operate normally.
This means the transponder 105 can be configured with losing little
to no operability. Over-the-air configuration commands change the
parameters used for processing physical and logical events on the
fly. Over-the-air operating system updates are achieved using two
executable code spaces, and a temporary code space for loading new
code. Once the uploading of new code into the temporary code space
is completed, the transponder reboots, copies the new code into the
secondary executable code space and resumes execution with the most
recent update.
[0086] FIGS. 4A-4G are exemplary screen shots of the user interface
for configuring the physical and logical events within the
transponder in one embodiment. FIGS. 4A-4G serve only as examples
of a general interface which the user can interact with to
configure the transponder 105. One important feature of the present
disclosure is that configuring the transponder does not require the
user to know scripts or hard-coded parameters. Instead, the present
disclosure includes a software application with which the user can
easily interface logical windows, tabs, fields, checkboxes and
radio buttons to configure the transponder.
[0087] FIG. 4A is a screen shot of a window that interfaces with
the user to configure the transponder 105. The window 400 has at
least four tabs 401 from which the user can choose. The first tab
402 directs the user to a window 400 for configuring the modem of
the transponder 105.
[0088] The second tab 403 directs the user to a window 400 where
the user can configure at least 8 Inputs 345 and at least 4 outputs
355. FIG. 4C depicts the interface when the second tab 403 is
selected. The activity level 407 of the inputs 345 can be
configured to be either high or low. The outputs 355 can be
configured to default to an active or inactive state at startup
using the "On" field box 410. The outputs 355 can be further
configured to be associated with an LED acknowledgment 411. The
outputs 355 can be assigned to any type of control mechanism or
function within the vehicle or article where the transponder 105 is
mounted. For example, the outputs 355 can be assigned with a door
locking mechanism in a vehicle. In this example, if Output 1 355 in
FIG. 4C is associated with a door locking mechanism, the user could
check the "On" 410 field box. When the transponder first boots, the
door locks connected to output 1 would automatically lock, and
would remain locked until unlocked by an over-the-air command. When
an output is selected as an LED acknowledge, that output will
change to an active state during an acknowledgeable priority event,
and blink to off when that priority event is acknowledged by the
Response Center.
[0089] The third tab 404 directs the user to a window 400 where the
user can configure certain logical events. FIG. 4D depicts the
interface when the third tab 404 is selected. The logical events
412-420 in FIG. 4D are exemplary only. Moreover, the present
disclosure contemplates a variety of configurable logical events
not depicted in FIG. 4D. The logical events 412-420 selected in
FIG. 4D are individually discussed below. Each event has a
corresponding field box in which the user can fill in the
appropriate value.
[0090] The fourth tab 405 directs the user to a window 400 where
the user can configure the inputs 345 and specific features of the
transponder 105. FIGS. 4E, 4F, and 4G depict the interface when the
third tab 404 is selected. As stated above, each input can be
assigned a corresponding event. For example, an input 345 can be
assigned to the ignition of a vehicle. Thus, occurrences associated
with the ignition of the vehicle are communicated and displaced as
a specific input 345. The user has the ability to configure each
input 345 and each feature 429-445 by enabling the input or feature
424, assigning the events as a priority event 425, assigning one or
more outputs 426 to the events, or link the occurrence of the
events to a messaging sent via the cellular network 427.
[0091] Events can be physical or logical. Physical and logical
events trigger the sending of a message over the air when certain
conditions are met. Most logical events are based on rules using a
combination of the GPS position and one other factor such as time
or speed. The event message triggered by physical and logical
events includes the event message itself and such information
includes latitude, longitude, speed, direction, time, state of all
the inputs 345, odometer, event reason or source, and any other
relevant information. The logical events are usually software
driven, calculation based, and typically draw from GPS positions.
The transponder 105 is configurable to include as few or as many
logical events as the user desires. One embodiment includes at
least six different configurable logical events.
[0092] The first logical event of one embodiment is a feature that
reports the last known location of the transponder for a specified
interval of time. This time reporting 412 features is depicted in
FIG. 4D. The status report to the user may consist of other
parameters such as latitude, longitude, speed, direction, time and
the state of the inputs 345. For example, FIG. 4D shows an example
where the user configured the time reporting 412 interval for 60
seconds. This means that in this scenario, the last known location
status and applicable parameters are reported every 60 seconds.
This time reporting feature 412 gives the user flexibility and the
option to lower the cost of data transmission. FIG. 4D also depicts
an entry for Satellite Timed Reporting Interval 413, where the same
time reporting feature is applicable, only the message is
transmitted via an optional satellite modem. Again, due to the
typically higher costs of satellite communication, the user has the
flexibility to determine how often he or she wishes to incur the
cost of satellite reporting on a fixed time period.
[0093] The second logical event of one embodiment is a feature that
further refines the reporting capabilities of the time reporting
feature 412. This event is depicted as Smart Time Reporting 414 on
FIG. 4D. The Smart Time Reporting 414 feature functions to transmit
a report only when the vehicle has moved a pre-selected distance
since the last transmitted report. FIG. 4D shows that the Smart
Time Reporting 414 feature is configurable in terms of a time
interval 415 and distance 416. Thus, a user could configure the
transponder 105 to report its location and applicable parameters by
selecting a timed reporting interval 415 in terms of seconds and a
distance 416 in terms of meters. For example, a user could select
the time reporting interval 415 for 60 seconds and the distance 416
for 1000 meters. This would mean that every 60 seconds the
transponder would send a report unless the transponder 105 has not
moved at least 1000 meters since the last report. This smart time
reporting 414 feature allows the user to tailor the amount of
reporting and the cost of data transmission.
[0094] Another contemplated reporting feature, not depicted, is a
scheduled reporting feature. This feature sets the transponder's
reporting feature on an interval based upon a date and time
reference. Thus, the user can configure the transponder to report
location and the other parameters on pre-selected days and hours of
the week. For example, a user could use the scheduled reporting
feature to configure the transponder to only report at 8 am, 12 pm
and 4 pm on weekdays and only once per weekend day. Also not
depicted is satellite scheduled reporting where the same scheduled
reporting capabilities are applicable, only the message is
transmitted via an optional satellite modem.
[0095] A third logical event of the one embodiment is a speeding
feature. The transponder 105 can be configured to send reports
dependent on the speed of the vehicle or article to which the
transponder 105 is mounted. FIG. 4D shows that the user can
configure the transponder 105 for at least two different settings
concerning speed. Specifically, the user can select the excessive
speed 417 and a speed filter time 420. The excessive speed 417 is
configurable for the user to select a maximum speed threshold for
the vehicle or article. Thus, each time the speed threshold is
exceeded, events are generated, recording when the threshold was
exceed, the maximum speed reached when above the threshold and when
the unit crossed below the threshold. When the transponder 105
crosses back below the threshold, the event message indicating this
occurrence as well as a third message indicating the maximum speed
reached during the period when the transponder 105 was above the
speed threshold is transmitted. The speed time filter 420 gives the
user the option to set a time period in terms of seconds to allow
the vehicle or article to cross the speed threshold without sending
a message. This filter also acts to make data transmission
efficient. For example, the user can set the speed time filter 420
for 15 seconds, which allows the vehicle to speed for 15 seconds
without sending a report. This scenario is beneficial for instances
when the vehicle is speeding to pass another vehicle or
accelerating to merge into traffic. Similar to the other logical
events, the event message also includes information such as the
latitude, longitude, speed, direction, time, and state of the
inputs.
[0096] A fourth logical event of one embodiment is an excessive
idle feature 421. The transponder 105 can be configured to send
reports dependent on the amount of time the vehicle or article has
been idle. FIG. 4G shows that the user can configure the excessive
idle 421 feature to be enabled 422, considered a priority event
425, assigned an output 426, or linked to a messaging system for
cellular phones 427. The excessive idle 421 feature generates an
event message whenever the maximum excessive idle time is reached.
The event message records the time and location corresponding to
when the threshold was exceeded. This feature is helpful to users
who wish to monitor or reduce the number of vehicles that have the
ignition turned on (using gasoline), but are not moving.
[0097] Geofencing
[0098] The next logical event of one embodiment is a "geofencing"
or creating configurable boundaries or geographical zones feature.
This feature consists of generating events when the transponder
travels through waypoints and zones. A configurable boundary or
geographical zone may be constructed through a combination of
waypoints and/or zones. Because of this combination, the
configurable boundary or geographical zone can be constructed in a
very specific shape and outline specific borders or routes. A
waypoint is a circular area defined by a geographical center point
and radius. The area defined by the waypoint is configurable by
changing the radius and the position of the geographical center
point. Thus, the boundary created by the waypoints and zones is
configurable.
[0099] In one embodiment, the transponder 105 is loaded with a
plurality of waypoints, each waypoint defined by a coordinate and a
radius. A zone can be defined by a plurality of waypoints. Thus,
for example, a city can be defined by two waypoints. Using GPS
data, the transponder will calculate whether it is in any of the
two waypoints defining the city. If the transponder determines that
it is inside one of the two waypoints, then the transponder 105
assumes that it is within the limits of the city.
[0100] A zone is an irregular region defined by a series of line
segments enclosing an area. In one embodiment, each zone contains 3
to 256 or more deflection points for creating the line segments
defining this irregular area. In one embodiment, this irregular
area can create a configurable boundary or a geographical zone. The
properties of a zone include a name, description and a flag
determining if the zone is an off-limits zone or an enclosed
zone.
[0101] In one embodiment, a geographical zone may be created
selecting a plurality of coordinates and downloading the
coordinates to the transponder 105. The plurality of coordinates
may be in the Mercator system. Next, the transponder 105 assigns
each coordinate to a pixel in a pixilated image that is loaded in
the transponder 105. In order to perform the assignment, the
transponder 105 utilizes logic to define a "bounding" square or box
around the plurality of coordinates. Then the bounding box is
pixilated and the pixels where the coordinates fall are marked as
activated. Once the pixels for each coordinate are assigned, lines
are extended from one pixel to the next so as to form an enclosed
area in the pixilated image. The pixels the lie in the path of the
lines between the activated pixels are also activated. Thus an
enclosed and contiguous line of pixels is formed.
[0102] Waypoints and zones are built by the operations data
processor 173. Once a waypoint has been built, it can be used in
transponder loads. Transponder loads are a collection of zones and
waypoints slated to be loaded on a transponder 105. These loads are
loaded on to the transponders with the configuration utility
172.
[0103] FIG. 4F illustrates a screenshot of the configuration
utility 172 for configuring waypoint and zone events. The
configuration utility 172 allows the operator to configure the
Waypoint Proximity enter feature 433, the Waypoint exit feature
434, the Zone Boundary enter feature 435, and the Zone Boundary
Exit feature 436. The Waypoint Proximity enter feature 433 monitors
when a waypoint has been entered, the Waypoint exit feature 434
monitors when a waypoint has been exited, the Zone Boundary enter
feature 435 monitors when a zone has been entered, and the Zone
Boundary Exit feature 436 monitors when a zone has been exited.
FIGS. 4F and 4G show the user interface of one embodiment where the
user may enable the waypoint and zone features, assign the events
as a priority event 425, assign an output 426 to the events, or
link the occurrence of the events to a messaging system for
cellular phones 427.
[0104] FIG. 5A illustrates a pixel map 500 of a zone. After all the
deflection points for a given zone are uploaded, the zone is saved
in the memory module 280 of the transponder 105 in the form of a
pixel map 500. The pixel map 500 is created by first drawing a
square around the entire area of the zone. The square is then
divided into an 80/80-pixel map. Each pixel 505 is a square. These
squares are then used to draw the outline shape 510 of the zone
515. A geographical area is then mapped to each pixel 505 of the
pixel map 500. A position fix 520 in the pixel map 500 is mapped
from the current geographical location of the vehicle.
[0105] A test is performed to for each zone for each position fix
520 in order to determine if the transponder 105 is inside the zone
515 or outside the zone 515. Thus, for each zone 515, the test
starts with a simple check if the position fix 520 is inside or
outside the pixel map 500. If the current position fix 520 is
inside the pixel map 500, a more extensive test is completed by
plotting the position fix 520 inside the bounding box and drawing
four lines in four directions (north, south, east and west) from
the position fix 520 to the borders of the pixel map 500.
Subsequently, the number of zone boundary crossings 530 is counted
for each of the four lines 525.
[0106] Multiple boundary crossing tests are performed for accuracy.
If a given line 525 crosses an odd number of zone boundaries 510,
the position fix 520 is considered inside the zone 515. If a given
line 525 crosses an even number of zone boundaries, the position
fix 520 is considered outside the zone 515. If at least three out
of the four boundary crossing tests agree, the zone boundary
crossings 530 are used to determine if the position fix 520 is
inside or outside the zone. If three out of the four boundary tests
do not agree, the position fix 520 is considered outside the zone
515.
[0107] Position fixes 520 that are on the special locations in the
pixel map 500 can yield specific location results. In one
embodiment, position fixes 520 that land on a zone boundary 510 are
determined to be outside the zone boundary 510. In another
embodiment, position fixes 520 that land on a zone boundary 510 are
determined to be inside the zone boundary 510. In one embodiment,
position fixes 520 that land on a "long and narrow protrusion"
which is only one pixel wide can be considered to always be inside
the zone 515. In another embodiment, position fixes 520 that land
on a "long and narrow protrusion" which is only one pixel wide can
be considered to always be outside the zone 515.
[0108] After all the deflection points for a given zone are
uploaded, the zone is saved in the memory module 280 of the
transponder 105 in the form of a pixel map 500. The pixel map 500
is created by first drawing a square around the entire area of the
zone. The square is then divided into an 80/80-pixel map. Each
pixel 505 is a square. These squares are then used to draw the
outline shape 510 of the zone 515. A geographical area is then
mapped to each pixel 505 of the pixel map 500. A position fix 520
in the pixel map 500 is mapped from the current geographical
location of the vehicle.
[0109] FIG. 5B illustrates a pixel map 550 of a geographical zone.
The pixel map 550 is first presented to the user as a geographical
map on a screen connected to a computing device. In one embodiment,
the user then selects a rectangular shape 555 around the
geographical area 560 that the user desires to define. In another
embodiment, the user may define a customized shape. The rectangular
shape is then divided into smaller rectangles such that the area of
the rectangle is divided into a grid. Each pixel in the grid can be
activated to be part of the geographical zone. In one embodiment,
the user may activate each pixel by double-clicking on each pixel.
In another embodiment, the user may select a smaller rectangular
region and mark the smaller rectangular region as being part of the
geographical zone 560 so that the pixels contained in the smaller
geographical zone are activated. In yet another embodiment, the
user may select a circular area as being part of the geographical
zone 560, and all pixels in such circular area would be activated.
In another embodiment, the user may define any customized
geometrical or non-geometrical shape.
[0110] Once all the desired pixels are selected by the user as
being part of the geographical zone 560, the rectangular shape 555
is mapped into a pixilated computer image. In one embodiment, the
pixilated computer image contains the same number of pixels as the
number of sections in the grid. The pixilated computer image can
then be loaded to the transponder 105. The transponder 105 can be
programmed to determine the position of the entity with a simple
calculation of whether the pixel in which the transponder's
location falls is activated or deactivated. In another embodiment,
the geographical zone is defined by selecting a rectangular region
and a circular region. The circular region can be defined by a
waypoint.
[0111] An irregular zone or geographical zone may be defined by a
collection of waypoints and pixilated images. Furthermore, each
irregular zone may have additional parameters such as speed
threshold of the entity, flagged as a "no-fly zone," color coded in
order of danger or security threat, communication enabled or
disabled, etc.
[0112] When the transponder 105 enters or exits waypoints and
zones, an event message is transmitted indicating what reference
point or zone has been entered or exited. The event message can
include latitude, longitude, speed, direction, time, state of the
inputs, odometer, event reason or source, and any other relevant
information. Thus, the zone boundaries and waypoints allow the user
to track a vehicle or an article through configurable boundaries or
geographical zones such as state borders or a specified route.
[0113] In one embodiment, the waypoint and zone events are
configurable to one or more assigned outputs. Meaning, when the
transponder 105 enters or exits waypoints and zones it can initiate
an output. An output can consist of an LED light unit within the
vehicle or article, a door locking mechanism, a fuel valve
mechanism and so forth. This means that the user can configure the
vehicle to lock its doors or close a fuel valve if the vehicle
enters or exits a specific waypoint or zone.
[0114] Commands
[0115] The transponder 105 is also configurable to respond to
various query and set commands sent over the air. The position
query commands the transponder 105 to return the last valid GPS
position, speed, direction, time, input state, and other relevant
information. The transponder can also be configured to respond to
an odometer query. Upon receiving this query command, the
transponder 105 returns the last valid GPS position, speed,
direction, time, input state, running odometer value, and other
relevant information.
[0116] The transponder 105 is also configurable to respond to
various query commands sent over the optional satellite modem. The
satellite position query commands the transponder 105 to return the
last valid GPS position, speed, and time. The transponder 105 can
also be configured to respond to a satellite odometer query. Upon
receiving this query command, the transponder 105 returns the state
of its inputs and running odometer value. Examples of other forms
of query commands that are sent to the transponder 105 are Input
and Output Signal Query, Analog to Digital Levels Query, Passenger
Count Query, Firmware Version Query, Satellite Status Query,
Satellite Position and Velocity Query, Satellite Odometer and IO
Query, etc.
[0117] Another optional command is the alarm acknowledgement. This
command is sent to the transponder 105 to terminate the sending of
a priority event (panic, medical or roadside assistance are
examples of priority events). When the alarm acknowledgement is
received, no further priority messages for the current event are
transmitted.
[0118] In one embodiment, the command is setting a single output.
This is used to change the state of an output to either active or
inactive over-the-air. An example would be to unlock the back door
of an armored truck when it arrives at the bank or turn on the fuel
pumps for a tanker truck when it arrives at a gas station.
[0119] In another embodiment, the command may be to send a text
message, from the transponder 105 through the communications
network to a device configured to receive and interpret text
messages.
[0120] In another embodiment, the command is a configuration
command to configure functionalities of the transponder 105 as
previously discussed. Examples of configuration commands include
Configure Timed Reporting, Set Odometer, Upload New Firmware,
Configure Excess Speed Event, Configure Excessive Idle Event,
Configure Satellite Timed Reporting, Configure Power Level
Critical, Configure Satellite Communication Port, Enable Event,
Configure Priority Events, Enable Cellular Message, Enable
Short-Range Radio Message, Assert Output Event, Configure GPS
Filter, Enable Input, Set Passenger Count, Configure Smart Timed
Reporting, Configure Scheduled Reporting, Configure Satellite
Scheduled Reporting.
[0121] The transponder 105 also may include a history reporting
component. Whenever the transponder 105 cannot transmit data
packets due to a lack of coverage via the principle communication
mediums, the packets are stored in one of at least two history logs
on an on-board flash memory storage device. When the transponder
determines that the communication link has been re-established, any
packets stored in memory are sequentially transmitted, beginning
with those messages identified as a priority. For example,
emergency or roadside assistance would be a priority message which
would be the first message transmitted when the connection is
re-established.
[0122] In an effort to combat GPS drift, two parameters are
included to filter GPS positions received from the GPS receiver.
The two filters are based upon maximum allowed speed and maximum
allowed acceleration. The parameters can be customized to the type
of installation. If a packet is received from the GPS receiver and
either of these two parameters is exceeded, the position packet is
thrown out.
[0123] Backend Control System
[0124] FIG. 6 illustrates a backend control system 150. The backend
control system 150 includes a plurality of gateway systems 151-153,
a codec 155, and an asynchronous routing system 159. In turn, the
asynchronous routing system 159, includes a web server 156, a
plurality of router systems 620, 622, a real time database 630, a
history database 642, and a fleet database 670.
[0125] The real time database 630 maintains records of the most
recent information from a transponder such as location, speed,
direction, odometer reading, etc. The history database 642
maintains records of all events and transactions that were received
and sent from the asynchronous routing system 159. Finally, the
fleet database 670 keeps records of all the administrative entities
such as the controlled mobile and static objects to which a
transponder is attached to (e.g. a vehicle), users, transponder
configuration, fleets, etc.
[0126] The backend control system 150 can be configured to run on
any combination of computer servers. In one embodiment, the
plurality of communication gateway systems 151-153 runs on
independent computer systems. In another embodiment, the
communication gateways 151-153 run on a common computer system.
[0127] The communications gateway systems 151-153 direct data flow
from each of the transponders 105 into the backend control system
150. The gateway systems 151-153 also direct commands and queries
to the appropriate transponder 105. Each gateway establishes and
maintains a communication link with a communications network
651-653. In one embodiment, the gateway is a Universal Datagram
Protocol/Internet Protocol (UDP/IP) packet receiver and sender 151,
which connects to an Internet/cellular network 651. There may be
more than one UDP/IP gateway 151 transmitting and receiving data.
The UDP/IP gateway 151 allows the backend control system 150 to
communicate with transponders 105 over GSM/GPRS, CDMA/1xRTT and
CDPD networks using UDP packets.
[0128] In another embodiment, the gateway system is a Short Message
Peer to Peer (SMPP) gateway 152 that connects with a Short Message
Service (SMS) network 652. A plurality of SMPP gateway systems 152
transmit and receive data for transponders that communicate over
SMS networks using an SMPP protocol. Each SMPP gateway system 152
opens and maintains a continuous connection to the service
provider's Short Message Service Center (SMSC) for incoming data so
that reception of transponder 105 data from the SMSC can be
guaranteed.
[0129] In another embodiment, the gateway system is a satellite
gateway 153 that connects to a satellite network 653. As
illustrated in FIG. 1A, the satellite network 653 may include one
or more satellites 130 and, at least on ground station 145. The
satellite gateway 153 transmits and receives data for transponders
105 that communicate through satellite communication. In one
embodiment, the satellite communication protocol may be that of
Inmarsat satellites using eight-byte packets of data. The satellite
gateway 153 opens and maintains a continuous connection to the
satellite network 653.
[0130] The communication between the asynchronous routing system
and transponders are channeled through an appropriate gateway
system 151-154. An appropriate gateway system 151-154 is selected
based on a unique combination of transponder manufacturer,
communications protocol and service provider. For example, a
transponder 105 that uses CDPD communication would be routed
through a different gateway system 151-154 than a transponder 105
that uses SMS communications protocol. Likewise, transponders 105
that use the same communications protocol such as CDPD, but have a
different service provider would have separate gateways.
[0131] As the gateway system 151-153 receives each inbound packet
of data, the gateway system 151-153 tags each packet with the date
and time of arrival, the transponder 105 manufacturer information,
the transponder's 105 address information, and repackages the
packet for transmission to the codec 155. The gateway 151-153 then
writes the repackaged data into a queue 665 that is read by a codec
155.
[0132] When the gateway system 151-153 receives an outbound packet
from an outbound queue 661-664, the gateway system 151-153 uses the
address information to send the packet to the target transponder
105. If required, the gateway system 151-153 verifies before
transmission that the gateway system 151-153 has an open and valid
connection to the corresponding network 651-653. Each gateway
system 151-153 has at least one corresponding outbound queue
661-663. For example, each UDP/IP gateway 151 has at least one
outbound UDP/IP queue 661. Each SMPP gateway 152 has at least on
outbound SMS queue 662. Each satellite gateway 153 has at least one
outbound satellite 663. Each SMTP mail gateway 154 has at least one
outbound SMTP queue 664.
[0133] After a packet is placed in the inbound queue 665, the data
coming from various networks is decoded into a standard data
format. Likewise, before a packet is placed in an outbound queue
661-664, the data going to different communications networks is
coded from the standard data format, into a network specific
format. The coding and decoding of data is carried out by the codec
(coder-decoder) 155. The codec 155 permits the greater flexibility
because the introduction of new communication network protocols is
transparent to the asynchronous routing system 159. Thus, if a new
transponder model uses a new communication network protocol, the
backend control system does not need to be upgraded. The system
upgrades needed would be a codec 155 update and a new gateway if
necessary.
[0134] When a packet comes into the asynchronous routing system
159, each inbound packet that the codec 155 receives is first
examined to determine the transponder model. If the codec 155
supports the specified transponder model, the data is translated
from the transponder 105 proprietary format into the standard
system format. Once the codec 155 has interpreted the data, the
codec 155 then writes the data into a response queue 610. If the
codec 155 does not recognize the transponder model, the codec 155
then logs the unsupported data and emails the data to a designated
system or network technician.
[0135] When a packet is sent from the asynchronous routing system
159 the codec 155 determines the transponder model to which the
packet is sent. If the codec 155 supports the specified transponder
model, the data is translated from the standard system format into
the transponder 105 proprietary format. Likewise, if the packet is
sent to another device that is not a transponder 105, the codec
determines if it supports that device, and if so, translates to the
appropriate format. Once the codec 155 has interpreted and encoded
the data, the codec 155 then places the packet into the queue that
corresponds to the appropriate type of network communication
protocol. An SMS packet data would be placed into the outbound SMS
queue 662. If the codec 155 does not support the transponder model,
the codec 155 then logs the unsupported data and emails the data to
a designated system or network technician.
[0136] Once a packet is processed by the codec 155, it is then
processed depending on if it is an outbound or inbound packet.
Outbound packets are placed in the appropriate outbound queue
661-664. Inbound packets are received by the asynchronous routing
system 159 in a response queue 610. The response queue 610 feeds
the packets to the response router 620. The response router 620
determines if a client console 176 is tracking the transponder 105
associated with the incoming message. If so, the response router
620 routes the incoming message to the appropriate client console
176. Thus, the client console receives the message before any other
process in the asynchronous routing system 159. If no client
console 176 is tracking the transponder 105 associated with the
incoming message, the response router 620 places the incoming
message into a new event queue 621. The new event queue 620 feeds a
new event router 622. The new event router 622 analyzes each
incoming message and determines if the incoming message is
associated to a new priority event for the transponder 105. The new
event router 622 determines if the incoming message is associated
to a new event by searching a real time database 630 for a similar
event associated to the transponder 105. If no event is recorded
for the transponder 105, or the event is of high priority, the new
event router 622 sends a routing request to all client consoles 176
that have permission to view the incoming message. The request is
intermittently sent until at least one client console 176 accepts
the routing request. Once the routing request is accepted, the
client console 176 adds the transponder 105 to an inventory in the
client console 176 so that the incoming message can be handled.
[0137] Asynchronously, a history queue 640 receives the inbound and
outbound messages for all transponders 105. The inbound messages
are fed from the history queue 640 to the history recorder 641. The
history recorder 641 geocodes all packets that have valid latitude
and longitude. The geocoded information is saved in a history
database 641 to be used later for reporting and statistical
analysis.
[0138] Incoming messages from transponders 105 may also be
forwarded to an email address, or cellular telephone, or any other
communications device. To achieve this functionality, the history
recorder 641 also transmits the geocoded locations to remote notify
routers 681 by placing the geocoded locations in a remote notify
queue 680. The remote notify router 681 that receives the geocoded
location and event information queries the fleet database 670 to
find out if the configuration information associated with the
transponder 105 requires a notification to a communications device
177. If a notification is required, the remote notify router 681
retrieves the contact information for the appropriate
communications device 177. The remote notify router 681 then
formats and encodes the message sent to the communications device
177. The message is placed in the outbound SMTP queue 664 to be
sent through the SMTP gateway 154. The message can be placed in the
outbound SMS queue 662 to be sent through the SMPP gateway 152.
[0139] The real time database 630 is also updated with the new
event information associated with the incoming message. Thus, the
real time database 630 contains the latest information reported on
a given transponder 105. The real time database 630 is connected to
a web server 158. The web server 158 is directly connected to the
Internet 160 and allows users of a web tracking application 171 to
make location requests, command requests 632 and report requests
633. When a web server 158 receives a location request 631 from the
web tracking application 171, the web server 158 queries the
history database 642. The history database 642 contains all events
in chronological order. The web server 158 retrieves all
transactions related to the web tracking application 171 query and
forwards the data to the web tracking application 171 for display
in a web browser.
[0140] When a web server 158 receives a location request 631 from
the web tracking application 171, the web server 158 queries the
real time database 630 for the corresponding transponder 105
information. The real time database 630 provides transponder
information as related to the very last incoming message from the
incumbent transponder 105. The web tracking application 171 may
also send a command request 632 such as querying the position of
the transponder. The command request 632 is sent to the command
receiver 690, which in turn processes the position request command
by tagging the appropriate transponder 105 information. The message
is encoded by the codec 155, placed in the appropriate outbound
queue 661-663 and sent through the corresponding gateway system
151-154 to the transponder 105. The transponder 105 will then send
back a response, and the backend control system 150 then processes
it by updating the real time database 630. After the real time
database 630 has been updated, the web server 631 may refresh the
contents of the web tracking application 171 showing the new
position of the transponder 105.
[0141] The command receiver 690 processes all commands pertaining
to all outbound messages to be sent to transponders. The command
receiver may receive command messages from the client consoles 176,
the administrator consoles 175, or from the web server 158. When
the command receiver 690 receives a command message, the command
receiver 690 tags each outbound message with the correct
transponder 105 address by searching a fleet database 670 and
retrieving the address information. Each message is sent by the
command receiver 690 to the codec 155 for encoding.
[0142] All of the commands that are processed by the command
receiver 690 are ultimately sent remotely to the transponder 105.
In one embodiment, the command is a Position Query. Upon receiving
this query command, the transponder 105 returns the last valid
position, speed, direction, time and input state. In another
embodiment, the command is an Odometer Query. Upon receiving this
query command, the mobile products return the last valid GPS
position, speed, direction, time, input state, and running odometer
value. In another embodiment, the command is an Input/Output Query.
Upon receiving this query command, the transponder returns the last
updated state of all inputs and all outputs (active/inactive). For
any given input, the active state is relative to that the
configuration of that input. For instance, if an input is
configured to be active-low (H-L), then 0 volts at the input
translates into that input being "active." If the input is
configured to be active high (L-H), then 12/24 volts at the input
translates into that input being "active." In another embodiment,
the command is a Time Report Set and/or Home IP. This command is
sent to the transponders to configure the reporting interval for
the Timed Reporting feature of the firmware. This command can also
be used for setting the transponder's destination IP/MIN address.
This command allows the transponders to be reconfigured
over-the-air to transmit to a new control center or home address if
the IP/MIN address of the control center or home address changed.
In another embodiment, the command is Set All Outputs. This command
is sent to the transponder to set all outputs simultaneously. Any
individual output can be either high or low. In another embodiment,
the command is Set Single Output. This command is sent to the
mobile products to set one individual output either high or low. In
another embodiment, the command is Enable/Disable Inputs and
Events. This command is sent to the transponders to enable/disable
all known transponder features. Both physical and logical events
can be individually enabled and/or disabled. While the physical and
logical events can be disabled, the ability to query the
transponder for its location and status can remain enabled. In
another embodiment, the command is an Alarm Acknowledgment. This
command can be sent to the transponder to terminate the sending of
an emergency event such as panic, roadside assistance, or medical
assistance. When the alarm acknowledgement is received, no further
emergency messages for the current event are transmitted from the
transponder 105.
[0143] The asynchronous routing system 159 interacts with various
control consoles. Reporting consoles 174 connect to the fleet
database 670 to display fleet information. Administrator consoles
175 also connect to the fleet database to retrieve transponder,
vehicle, and user information. Administrator consoles 175 also
connect to the command receiver 691 to send commands to the
transponder 105. Operations data processors 173 connect to the
fleet database 670 in order to retrieve configuration information
for a specific user or transponder 105. Finally, the client console
176 receives information for a tracked transponder 105 from the
response router 620, receives information for a non-tracked
transponder from a new event router 621, and retrieves information
from the fleet database 670. The client console also transmits
commands to a transponder 105 by sending the command to the command
receiver 691.
[0144] Management Software
[0145] FIG. 7A illustrates a screenshot of an instance of the
client console 176. The client console 176 provides real-time
transponder 105 location mapping, location tracking, transponder
control and transponder message/event handling.
[0146] In one embodiment, the client console 176 connects to map
databases and transponder databases by configuring multiple
parameters. Such parameters can include path definition for the
console map sets 710, any custom data sets 711, map information
display symbols 712 and console operating procedures 713. The
Settings are maintained in the system registry and recalled at
program load. In another embodiment, the client console 176
provides the ability to configure mapping parameters used by the
client console 176. The client console 176 also provides the
ability to define the console location, default zoom levels when
displaying the various program-generated maps, the map set to be
used and whether or not street locations are displayed when mapping
a location. FIG. 7B illustrates a screenshot of an instance of the
client console 176. A graphical user interface allows maps to be
displayed on the client console 176. In one embodiment, the client
console 176 displays all available transponders on one master map.
In another embodiment, the client console 176 allows a user to view
transponders by groups 721 or individually 720. In another
embodiment, the client console allows a user to view all
transponders that come within an area 722 displayed by the map. In
another embodiment, the client console 176 allows a user to view
all transponders that are within a waypoint. In another embodiment,
the client console 176 allows a user to view all transponders that
are within a zone.
[0147] The client console 176 allows a user to employ a variety of
mapping tools to help manage transponder 105 location processing.
Provided tools include map zoom in/out, map pan, map feature label,
map ruler, map location at selected point, map legend, center map
on selected point, find a map feature and center map on it, display
information for a selected custom dataset element, display
information for a selected transponder, display information for a
standard map feature and print the displayed map.
[0148] Further, the displayed map uses color-coding for both
location symbol and location identification to indicate special
conditions relating to the transponder 105. Special situations that
are color-coded include transponder moving, transponder stopped,
transponder not reporting, transponder location is old and
transponder has a priority message active.
[0149] As illustrated by FIG. 7C, the client console 176 can
generate a user-operating log that includes all messages received
by the console 740, commands sent by the console 741 and key events
742 that occur during console operation. In another embodiment, the
generated log is interactive such that a user can append a free
form remark to the event log and recall and view the event log for
any selectable time period. In another embodiment, the client
console 176 provides the ability to generate a summary list of the
assigned transponder inventory and the current real-time status of
a selected transponder.
[0150] FIG. 7D illustrates a screenshot of the client console 176
with a generated list displaying a transponder summary table 750
and a master map 751. The client console also allows the user to
view a chronological listing of all messages 752 received at the
client console 176 and all commands 753 transmitted from the client
console 176 to the transponder 105.
[0151] The transponder summary table 750 displays all transponder
information and is updated in real time as the transponder reports
to the client console 176. The transponder data shown are the data
corresponding to the transponders belonging to the inventory of a
user. The transponder summary table 750 uses icons and color-coding
to alert the user to special conditions. Special situations that
are color-coded include transponder moving, transponder stopped,
transponder not reporting, transponder location is old and
transponder has a priority message active. In another embodiment,
the user has the ability to find any item in the transponder
summary table 750, select which columns are visible and to sort the
table according to selectable sort types and sort orders for up to
three columns.
[0152] In another embodiment, the client console 176 provides a
user the ability to select an item in the transponder summary table
750 and perform an operation that is related to the selected item
or its group. For example if a transponder is selected, various
operations related to the transponder may include adding the
transponder to the master map, removing the transponder from the
master map, creating a group map, creating an individual map,
centering the map on the selected transponder location, viewing the
input/output/and event states for the transponder, setting the
message notification mode for the transponder, viewing an
information screen that contains detailed information from the
master database pertaining to the transponder and viewing any
supplementary information contained in the location data packet
that is not otherwise displayed.
[0153] In another embodiment, the client console 176 provides a
user the ability to select a transponder in the transponder summary
table 750 and send a command/query to the selected transponder. The
command/query list available to the user is dependent on the user's
profile in the master system database. In another embodiment, the
command is sent from a web based client console such as the web
tracking application 171.
[0154] In another embodiment, the client console 176 provides a
user the ability to receive popup alert notification, including a
sound cue, whenever a message event, a standard event or priority
event is received at the client console 176. Notification modes may
be enabled or disabled for each transponder. In one embodiment, the
notification modes are configured in the fleet database 670. In
another embodiment, the notification modes are configured locally
in the client console 176. When a priority message is received, the
user has the ability to cancel the message, switch reporting to the
emergency mode, or continue to use the standard reporting mode. The
transponder summary table 750 displays priority messages with a
special icon under the transponder identification column.
[0155] FIG. 8 illustrates a screenshot of an instance of the
administrator console 175. The administrator console 175 allows the
creation and maintenance of client configurations. The
administrator console 175 updates the fleet database 670. As FIG.
7B illustrates, the administrator console 175 allows access to each
fleet by displaying a list of fleets 820. Each fleet may be
accessed to view and manage all the vehicles associated to the
selected fleet. A list of vehicles 821 is associated with each
fleet in the list of fleets 820. Each vehicle in the list of
vehicles 821 has a corresponding list of transponders 822,
passengers 823 and operators 824. Each transponder in the list of
transponders 822 may be selected for configuration. Likewise, the
list of operators 824 may be selected to add, edit or delete an
operator. The list of passengers 823 may be selected to add, edit
or delete a passenger for the corresponding vehicle.
[0156] FIG. 9A illustrates a screenshot of an instance of the
operations data processor 173. The operations data processor 173
allows one to create and maintain zones, waypoints and transponder
loads for the transponder 105. Zones, waypoints and sites are
created and maintained with a point-and-click mapping interface as
illustrated by FIG. 9A. The graphical interface provided by the
operations data processor 173 displays a map 910 of the area where
a waypoint 920 is to be installed. In one embodiment, the graphical
interface allows a user to expand or reduce the radius 930 around
the waypoint. In another embodiment, the radius information is
entered by typing the number on a given field of the graphical user
interface. The operations data processor 173 allows one to maintain
a list of waypoints 940 and view each waypoint 920 in a the
corresponding map 910.
[0157] FIG. 9B illustrates a screenshot of an instance of the
operations data processor 173. The graphical interface provided by
the operations data processor 173 displays a map 910 of the area
where a zone 950 is to be delineated. The zone 950 is defined by
deflection points 951 and the lines that connect the deflection
points 951. The deflection points 951 may be indicated by clicking
on the map 910. A list of zones 960 are also displayed by the
operations data processor 173, along with a collection of
deflection points 970. Each zone 950 can be edited by changing the
deflection points 951.
[0158] FIG. 9C illustrates a screenshot of an instance of the
operations data processor 173. The graphical interface provided by
the operations data processor 173 displays a window to configure
transponder loads. A transponder load is a collection of zones and
waypoints to be loaded to a transponder. Each client edits a
collection of transponder loads. The transponder loads are later
downloaded to each transponder 105 according to the configuration
in the fleet database 670. A load is configured by selecting a
client 980, and selecting the desired waypoints 981 and zones 982
that were defined by the client 980. The waypoints 981 and zones
982 selected are those that will later be downloaded to the
transponder 105.
[0159] FIG. 10 illustrates a screenshot of an instance of the
history data processor 173. The history data processor 173 permits
the retrieving and mapping of historical data and events associated
with selected vehicles and transponders. The graphical user
interface displays an interactive map 1010 and the geographical
points 1020 where an event occurred. In one embodiment, the history
data processor 173 allows the user to click on each geographical
point 1020 and see the event information 1030 reported at that
geographical point 1020. In another embodiment, the history data
processor 173 allows the user to select a group of geographical
points 1020 and replay the history of a transponder or of a vehicle
along the selected geographical points 1020. In another embodiment,
the history data processor 173 allows the user to select all
geographical points 1020 and replay the history of a transponder or
of a vehicle along the selected geographical points. In one
embodiment, the history replay will replay the movement of the
vehicle according to the streets traveled, the direction, and the
speed. In another embodiment, as the history of the vehicle is
replayed, the event information 1030 is displayed for every
geographical point 1020 reached.
[0160] In another embodiment, the history replay can replay the
history according to selected period. In another embodiment, the
history replay can replay the history as related to a selected
waypoint 920. In another embodiment, the history replay can replay
the history as related to a selected zone 950.
[0161] FIG. 10 illustrates a screenshot of an instance of the
history data processor 173. The history data processor 173 also
permits the retrieving and reporting of mapping historical data and
events associated with selected vehicles and transponders. In one
embodiment, a graphical user interface from a computer application
displays a list of available reports 1040. In another embodiment, a
graphical user interface in a web browser displays a list of
available reports 1040. Once an item in the list of available
reports 1040 is selected, the report 1050 is displayed to the user.
Each report 1050 is configurable to be generated based on multiple
parameter options such as a time period, types of events, types of
transponders, a specific transponder, a specific zone, a waypoint,
types of vehicles, a vehicle, etc.
[0162] FIG. 11 illustrates a screenshot of an instance of a disable
transponder processor 1100. The disable transponder processor 1100
allows an accounting department to disable transponders 105 for
nonpayment and enable them at the time of subscription or when
payment is made. In one embodiment, a disable transponder processor
1100 can be connected to the accounting processing data exchange
177. In another embodiment the disable transponder processor 1100
can be a stand-alone application installed on computer systems used
by an accounting department. In another embodiment the disable
transponder processor 1100 can be a web application accessible only
by members of an accounting department.
[0163] The disable transponder processor 1100 provides a list of
transponders 1110 that are disabled, and a list of transponders
that are enabled. If a user disables or enables a transponder 105,
the transponder configuration 105 is updated in the fleet database
670 and is also sent to the command receiver 690 for processing.
The command receiver 690 sends a message to the transponder 105 to
turn off its functions.
[0164] While the above description contains many specifics, these
should not be construed as limitations on the scope of the
disclosure, but rather as an exemplification of one embodiments
thereof.
[0165] The method and system described above contemplate many
applications of the present disclosure. The present disclosure
includes a system that has the capability to control and monitor a
moving object or a static object prone to be moved. The object can
be many things such as vehicle, aircraft, airborne items, animals,
persons, cargo, specialized and/or volatile cargo such as
chemicals, weapons, or hazardous materials. In addition, fragile
cargo can include, but is not limited to items such as, medicine,
patients, organs for donation, where monitoring parameters such as
temperature, pressure, humidity, blood pressure, ekg, and other
conditions are critical to the integrity of the item. Another
climate-sensitive object for which tracking, monitoring and local
control is beneficial includes produce and perishable goods. For
example, the transponder could monitor humidity and have the
ability to control the amount of moisture in cargo containing
perishable items that are susceptible to humidity. Moreover, these
objects can include any other item where tracking its movement
and/or location is beneficial. A transponder can be mounted,
attached, manufactured, or otherwise included upon or within these
various articles. The transponder is contemplated to be of many
different sizes including nano- and/or micro scale-transponder.
Within the context of the tracking system, the transponder works to
collect, process, and communicate various information about the
article or vehicle to which the transponder is attached.
Furthermore, when requested, the transponder can issue various
commands and instructions to the local article or vehicle. These
commands or instructions to the local article or vehicle are
contemplated to include any command that can change, alter, or
enhance, the mechanism, the function, the structure or the
composition of the article or vehicle. For example, a medical
application of the present disclosure contemplates a transponder
with the ability to monitor a patient's vital signs. The
transponder can be hardwired or hooked up to intravenous tubes,
medical machines, and other medical equipment. Thus, for example,
the user is capable of remotely administering medicine by
commanding the transponder to perform the function. Furthermore, a
change in vital signs could send an event message to the
transponder where the transponder could send a message to a
response center or directly to a cellular phone of the patient's
physician or to a plurality of cellular phones, such as to family
members, for example.
[0166] Additional applications and situations include military
applications where it is necessary to not only track and monitor a
vehicle or person, but where it is also beneficial to be able to
control functions on the vehicle or person. For example, it may be
desired to control the firing ability of a military vehicle, or
control similar functions once the vehicle enters a certain
territory or turn off certain capabilities once the vehicle enters
a peaceful zone. Similarly, an additional application to aircrafts
and airborne items considered. The transponder would have the same
capabilities; however, the transponder could position based upon on
a 3-D point in space, not merely longitude and latitude. Naturally,
each one of these applications remains configurable and
controllable over-the-air.
[0167] Furthermore, the disclosure includes any combination or
subcombination of the elements from the different species and/or
embodiments disclosed herein. One skilled in the art will recognize
that these features, and thus the scope of this disclosure, should
be interpreted in light of the following claims and any equivalents
thereto.
