Description
[0001] The present invention relates to control and monitoring of
electrical and electronic devices and, more particularly, to
intelligent power monitoring and signal transmitting and receiving
devices.

thereof) is used in this specification in the inclusive sense of
"having" or "including", and not in the exclusive sense of
"consisting only of". [0006] 2. The above discussion of the prior
art in the Background of the invention, is not an admission that
any information discussed therein is citable prior art or part of

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0091] Preferred embodiments of the present invention provide for a
small compact power monitoring and sensing unit 10 as for example
shown in FIGS. 1, 2 and 3. In a preferred form, the unit 110
comprises an enclosure 112 provided with connector pins 114
projecting from a first side 116 and sockets 118 for receiving like
connector pins at a second opposite side 120. The structure of the
unit 110 is such that it may be plugged into a mains electrical
power outlet 111, and in turn receives an appropriately configured
electrical plug 113 of any mains powered electrical device.
[0092] In preferred forms circuitry within the unit 110 is adapted
to monitor current flow through the unit to an accuracy of better
than .+-.50 mA. Power flow, including voltage and current is
sampled some hundreds of iterations per second to enable micro
management. The logic circuitry of the unit is able to provide a
power usage profile of an electrical device 115 connected to
it.
[0093] In addition to the power monitoring and logic circuitry, the
unit of the invention is provided with a transceiver module for
transmission and reception of data using short range wireless
communication technology, for example Wi-Fi and Bluetooth
protocols. Data may be transmitted to, or received from any
suitable transmitting or receiving device, including an Individual
Signal Unit as described in WO2008/134810, the contents of which
are incorporated into this specification by reference. Data may
also be transmitted to, and received from, nominated entities over
the internet via Wi-Fi and a wireless router. Communication between
nominated users and the unit may also be by means of a suitable
mobile phone over a mobile phone network, or directly by Wi-Fi,
Bluetooth or similar technology between the unit 110 and a
communication device such as a mobile phone.
[0094] The unit of embodiments of the invention may further be
provided with one or more environment sensing devices, including
for example ambient temperature and light level sensors and a
movement (PIR) sensor.
[0095] A programmable logic (CPU) chip incorporated in the unit may
be configured to switch the mains power flow through the unit to on
or off, depending on either the monitored power flow level, or
input received from any of the incorporated sensors. As well the
unit 110 is enabled to receive radio commands to switch the load
connected to the unit either on or off.
[0096] In one preferred embodiment, in a given environment such as
a room or office, one signal unit may act as a command unit
communicating with other slave signal units.
[0097] Thus the command signal unit may for example process power
consumption of a particular item of electrical equipment and
combine this data with a sensor input so as to determine a course
of action to be communicated to the slave units. This may include
switching the status of the power supplied to other electrical
equipment connected to the slave units, or the transmission of
monitored data from those units for example.
[0098] Configuration of the CPU may further include the
transmission of data in respect of any of the elements monitored by
the unit. Such data may include for example the switching of remote
appliances or electrical systems provided with appropriate
intelligent receiving capabilities. A default configuration of the
CPU may occur at time of manufacture of the unit, but custom
configuration by a user may be provided either via the ISU referred
to above, over the internet or over a mobile phone or similar
communication device. Custom configuration may include the
up-loading to the unit 110 of special applications programmed by
third parties and made available over the internet.
[0099] In one preferred embodiment of the invention, the signal
unit of the invention may be registered and communicate with, a
central control facility (CCF) as described in WO/2008/006155 and
WO/2008/134810. The CCF maintains servers and databases which store
protocols for procedures associated with data which may be received
from a signal unit registered with the CCF by an owner of that
signal unit. These protocols will direct certain steps to be
executed by the CCF dependent on the data received from the signal
unit. Steps executed by the CCF may include the switching to off or
on of power flow through a unit as noted above, or interrogation of
sensors.
[0100] The improved signal units of preferred embodiments of the
invention provide a powerful method of monitoring and controlling
power usage. A number of the units may be distributed around a
house or office building, plugged into power outlets, so as to
report on individual power usages of appliances connected at these
outlets. Software enabled on suitable receiving devices, such as
the ISU, mobile phone or other communication device, can then
display instantaneous power use of individual appliances or a
record of past usage, and allows a grouping of two or more usages
to assess cumulative power usage.
[0101] If a photovoltaic system is installed, the unit, when
suitably connected to the solar power generating circuit, can
monitor and display the power generated and any net power either
received from, or provided to, the mains electricity grid.
[0102] It will be understood that, given the power monitoring
capability combined with environmental sensing functions
incorporated in the unit, the software may be configured to provide
a variety of data outputs depending on the preferences of a
user.
[0103] FIG. 4 illustrates a circuit board 110A for a wall unit
comprising a power monitoring and sensing unit 110 and including at
least one plug-in point 121. The plug-in point 121 is adapted to
receive a pluggable module 122. The pluggable module 122 is shown
inserted in a circuit board 110A of a power monitoring and sensing
unit 110 in FIG. 5. The pluggable module allows for functionality
to be added to the unit 110 in a flexible way. In particular it
allows addition of functionality which may not be able to be
achieved merely by programming of the on-board microprocessor on
circuit board 110A. In one form the pluggable module 122, as
illustrated in FIG. 6, may take the form of an RF433 module adapted
for connection to an SD-style connection point.
[0104] The communications capability conferred by the RF433 module
may allow, for example, individual units 110 to communicate with
other like units 110 located in the same environment. In preferred
forms the communication range may be limited with the intention
that where a board 10E wishes to communicate with an ISU 123 but is
not within direct range of the ISU 123 it may yet communicate with
ISU 123 by a daisy chain arrangement whereby board 110E
communicates with adjacent board 110D which in turn communicates
with adjacent 110C, thence to board 110B, thence to board 110A,
which finally, communicates with ISU 123 the information which
board 110E wished to impart to ISU 123. This "mesh" capability
permits the effective range of communication of any individual
monitoring and sensing unit 110 to be increased well beyond its own
specific range. The ISU 123, in turn, may communicate with an
external communications tower 124, typically mobile
telecommunications tower, for example via the GSM system which in
turn permits communication over the internet and thence to a master
database of the type described elsewhere in this specification and
also in the Applicant's earlier filed WO/2008/134810 International
Patent Application.
[0105] With reference to FIGS. 8 through to 12 there is illustrated
an ISU unit 22 and a methodology for its use. The ISU 22 is adapted
for communication with the power monitoring and signal unit 10
described above whereby the two units work together to achieve
functionality which neither on its own can achieve. In effect the
functionality of both units is extended when operating in concert
and in communication with each other.
[0106] As illustrated in the inset in FIG. 1 the power data, for
example, monitored on Unit 10 can be communicated via ISU 22 to a
screen on a portable digital device 40 and represented graphically
as graph 41 on its screen 42. The same portable digital device 40
can be used to enter control parameters for programming and
reprogramming of unit 10 via ISU 22.
[0107] The following detailed description builds on the description
given in the applicant's earlier filed International Patent
Application PCT/AU2007/000958. In this instance, the features of
note relate to the "community of development" which the basic
system as previously described engenders and in respect of which
enabling disclosure is provided below. From one view the system
provides control over assets via the Internet irrespective of
distances involved and the mobility of the controller or the asset
and requiring only simple "do-it-yourself" installation. The system
is configured by the user via the Internet. The tools available for
configuration by the user can be provided in a wiki-style
collaboration by a multiplicity of third parties allowing the
features available to grow in a collaborative context over time.
Specific embodiments of the individual signal units 22 are
themselves programmable and re-programmable and configurable and
re-configurable in response to the imagination of the users and the
tools provided by the collaborating parties.
First Preferred Embodiment
[0108] With reference to FIG. 9 there is shown a reconfigurable,
collaboratively expandable monitoring system 200 in accordance with
a first preferred embodiment of the present invention. In this
instance the system comprises components as described with
reference to FIG. 10 (see below). The emphasis in this instance
revolves around the reconfigurability and collaborative input of
the system 200 whereby third party providers 201 (in this instance,
labelled P1, P2, P3 . . . PN) provide respective tools 202 (in this
instance, respectively nominated T1, T2, T3 . . . TN), which tools
are available for the user/owner/nominated recipient 30 of a
respective one or more individual signal units 22 to utilise so as
to define steps or actions to occur consequence to events detected
and reported by the individual signal units 22. The tools 202 are
made available to a user 30 preferably via a web interface screen
203 which will include a tool assembly pane 204 where an individual
user 30 can assemble a schedule of predefined steps 205 (step 1, 2,
3 . . . N) to in response to events 206 (event 1, 2, 3 . . . N).
The manner of assembly of the predefined steps is described in more
detail further in this specification. In this way a user 30 of one
or more of the individual signal units 22 can program responses to
events detected by the individual signal units 22 using tools 202
selected from an ever-increasing number of tools based on tools
supplied by third party providers 201.
[0109] FIGS. 9 and 10 are diagrammatic representations of the
apparatus and connections included in a monitoring system 10
according to a preferred embodiment of the invention. A central
control facility 12 includes a data processing server 14 and data
storage 16, linked to a transceiver 18. Central control facility 12
is in radio communication with a communication network such as a
mobile phone network, or for example as shown in FIGS. 9 and 10,
with at least one communication satellite 20, by means of
transceiver 18.
[0110] In the example of a communication satellite 20, it in turn,
is in telecommunication contact with a number of individual signal
units 22, for example via the Global System for Mobile
Communications (GSM), the General Packet Radio Service (GPRS) or a
similar communication network 21. Individual signal units 22 belong
to registered users of the system and may be located anywhere
within the signal footprint of a communication satellite (or
satellites) 20, or of some other communication network.
[0111] Individual signal units 22 each are assigned a unique
identifying code, and may take a number of physical configurations
depending on the environment in which they are to be located. FIG.
3 shows one preferred form of an individual signal unit, comprising
enclosure 50 with various input and output devices. In some
preferred forms at least, they will comprise a rugged, moisture and
tamper-proof outer casing with internal power supply and a
selection of bracketry and other attachment means for affixing the
devices to a variety of structures and surfaces. In other preferred
forms the device may be incorporated in an item of equipment at
manufacture, for example in the lantern structure of street
lights.
[0112] The apparatus of a monitoring system may include a number of
standard sensor devices available for purchase along with, or in
addition to the individual signal unit 22. Each sensor device is
adapted to respond to a predefined stimulus, and may include
sensors for power status, smoke detection, motion detection, door
or window opening, button press, fluid level, tampering, location
via the GPS system and video camera, for example. These standard
sensor devices are provided as a simple plug-in to the individual
signal unit 22, via one of the input connection 64 or USB port
shown in FIG. 4, or other standard interface ports provided on the
device.
[0113] An individual signal unit 22 may further be provided with
internal error monitoring facilities, such as a power supply
failure. Preferably also, individual signal units 22 are equipped
with interference sensors to alert the central control facility 12
of tampering by unauthorised persons, or disturbance by animals for
example.
[0114] Individual signal units 22 in at least one preferred
embodiment, are provided with output relays to activate one or more
external devices according to pre-programmed responses to sensor
monitored events. Examples may include the activation of audio
and/or visual alarms, the switching on of security lighting,
closure of fire doors and so forth.
[0115] The power supply and control module 42 is adapted to
maintain individual signal unit 22 in a passive, standby state
until receiving a signal from an external event sensor. Such a
signal initiates a powering up of the device, enabling it to
transmit its unique encrypted identifying code to the central
control facility. After transmission of this signal the individual
signal unit powers down and returns to its passive standby
state.
[0116] An individual signal unit 20 may also be brought into a
powered up state on command from the central control facility 12.
This powering up may be for the purpose of reprogramming the
individual signal unit 22 to install a new response procedure, for
example after the installation of a new, or an additional external
event sensor, relocation of the unit, or to modify an existing
procedure.
[0117] Where an individual signal unit 22 is provided with data
entry and display facilities, such programming or reprogramming of
the unit may be performed at the device itself. At the conclusion
of such local data input, the new or modified data is transmitted
to the central control facility to update its responses to any
signals received from the individual signal unit as required.
[0118] Referring again to FIGS. 9 and 10, during a powered up
state, as well as following any pre-programmed procedure for the
activation of any local connected devices, individual signal unit
22 will transmit a signal via the network 21 and a satellite 20,
reporting the event to the central control facility 12.
[0119] In a first simplest preferred form of the invention, a
signal sent by an individual signal unit 22 consists solely of its
unique encrypted identifying code. No data is sent with this code.
The information as to what a receipt of this code by the central
control facility means, is stored in the central processing
computers of the facility. This information, which is supplied by
and under the control of the registered owner of the individual
signal unit, may include instructions as to what actions are to be
taken in response to the signal.
[0120] Although in this preferred form of the invention, the
individual signal unit 22 is only enabled to transmit a single
encrypted identifying code, it may do so in various ways to
indicate various events. Each external event sensor is associated
with a unique sequence of repeat transmissions of said unique
identification code. For example if an external sensor device is
activated, the code may be transmitted a predetermined number of
times for that particular sensor at short intervals. However should
an error condition develop in the device itself, such as for
example a low battery situation, the code may be transmitted
singly. The manner of transmission of this single encrypted code is
then the determinant of the status of the device and of what action
should be taken by the central control facility.
[0121] According to its pre-programmed instructions, an individual
signal unit 22 may continue to transmit its signal at intervals for
a pre-defined period as an aid in location of the device by service
personnel alerted by the central control facility 12 as described
below.
[0122] Again with reference to FIGS. 9 and 10, a received signal is
acted upon by the central control facility 12, notifying any of a
number of nominated recipients 30 according to a pre-established
protocol negotiated between the registered user of the individual
signal unit 22 and the control facility. Notification of details of
a monitored event could be made in the form of an email via the
Internet 29 as shown in FIGS. 9 and 10, by facsimile transmission
or over the distributed network 21 to any personal communication
device.
[0123] Typically, one nominated recipient 30 will be the registered
user or owner of the individual signal unit from which the alerting
signal was received. However nominated recipients may also include
service providers, who are automatically notified of the occurrence
and the nature of the event, the location of the individual signal
unit and any other pre-defined details. Service providers may
include police, fire and ambulance services, or equipment servicing
personnel for example. At registration of an individual signal
unit, the owner of the unit may elect that third parties be
contacted only on receipt by the central control facility of
authorisation from the owner.
[0124] An applicant user or owner will be required to supply all
relevant details of the individual signal unit, its external event
sensing faculties, intended location and the procedures to be
implemented on receipt of a signal from the device. The central
control facility then issues the unique identification code for the
individual signal unit. Alternatively, an individual signal unit
may be pre-programmed at manufacture with its unique identifying
code. As well, the applicant user or owner nominates a service
provider of the GSM, GPRS or other communication system, for
billing purposes, or alternatively, the central control facility
makes this arrangement, with billing for such service included in
the overall charge for use of the system.
[0125] The information thus received is used by the central control
facility to program the procedure to be followed by the facility in
response to signals received from the individual signal unit. The
facility may also transmit data to the individual signal unit prior
to its commissioning but subsequent to its installation at the
infrastructure item, to set the parameters of signal transmission,
such as frequency and interval of repeat transmissions for
example.
[0126] With reference to FIG. 4 which shows an exploded view of one
preferred form of an individual signal unit 22, enclosure 50
comprises a base portion 52 and cover portion 54. Housed within
enclosure 50 are a communication module 56, for example using the
General Packet Radio Service (GPRS) standard for communication with
a communication network, and antenna jack 58. Also contained within
enclosure 50 is a rechargeable battery module 60, and various input
and output connections, including power input/outputs 62, sensor
inputs 64, device relay connections 66 and a universal serial bus
(USB port) 68. Individual signal unit 22 may also be provided with
status indicating light emitting diodes (LEDs) 70. Enclosure 50 is
provided with a space, for example space 72 on cover 54, for
display of a code used in the registration of the unit with the
central control facility.
[0127] Each individual signal unit 22 is adapted to monitor the
status of some aspect of an item of infrastructure, such as for
example illustrated in FIGS. 9 and 10, a gate 22, irrigation
control sluice 24 or tool shed 26.
[0128] As shown in the schematic of FIG. 11, individual signal
units 22 include at least a transceiver module 40, a rechargeable
power supply and power control module 42, at least one external
event sensor 44 and a logic circuit 46. For some applications, an
individual signal unit may be provided with, or connected to, a
magnetic card reader, enabling inspecting personnel to simply swipe
an authorising card as confirmation that the individual signal unit
is in its proper position and functioning, or that some predefined
task has been accomplished.
[0129] Preferably, the power supply 42 is rechargeable by means of
a solar panel 48, but may also comprise batteries rechargeable from
a mains power source, or replaceable battery packs. Where an
individual signal unit has been incorporated in some item of
infrastructure already provided with a power supply, such as in the
street light example, power to the unit may be provided from that
external supply.
[0130] An individual signal unit 22 may be provided with at least
one external event sensor 44 incorporated within the device itself,
but individual signal units 22 are more preferably provided with a
sensor interface allowing the unit to accept signals from a number
of external event sensors connected to the interface. Thus for
example, an individual signal unit 22 may monitor a number of
aspects of a remotely located facility, such as the doors and
windows of a building or various items of equipment located on a
service vehicle.
[0131] With reference to FIG. 12, the ISU may include the following
components.
[0132] GSM Engine 74.
[0133] This is the central core of the device. It includes a GSM
transceiver allowing the module to connect to and communicate over
the GSM network. The transceiver also makes use of the GPRS
capability of the GSM network to connect to a server of the central
control facility using IP sockets. The GSM engine also includes a
basic Python script interpreter to run application scripts
(software) and a battery charger 75 to allowing the charging of a
LiIon battery pack (connected via J5 on the circuit diagram of FIG.
12).
[0134] The application scripts (software) loaded into the GSM
engine 74 allow the module to monitor the external sensors and
devices connected to the ISU device and generate messages over the
GPRS network to the central control facility server whenever there
is a change in the status of these external sensors or devices. The
typical operation will be for the GSM engine to connect to a known
IP socket on a server at a known IP address. The message passed to
the server via this connection will include the identification of
the ISU device (typically the phone number associated with the SIM
card) and the details of the input status change.
[0135] The GSM engine has a push button switch (S1 on the circuit
diagram of FIG. 12) which allows the GSM engine to be turned on and
off.
[0136] Network Status Indicator (D1 on Circuit Diagram)
[0137] An LED (light emitting diode) is provided to give an
indication of the status of the ISU device. When the LED is
permanently off, the device is powered down. When the LED is
blinking quickly (approximately 1 second period), the GSM engine is
searching for the GSM network and attempting to register itself
with the network. When the LED is blinking slowly (approximately 3
second period), the GSM engine has registered itself with the GSM
network and is in a state that will allow it to make a connection
with a server should one of the inputs change state. When the LED
is permanently on, there is an active call being made by the
device.
[0138] Battery Status Indicator (D6 on the Circuit Diagram)
[0139] A visible indication of the charge status of the battery is
provided using an LED (light emitting diode).
[0140] USB Connection (J3 on the Circuit Diagram)
[0141] The ISU device has a USE connection to allow the module to
be connected to a Personal Computer. This connection allows the
application scripts (software) to be updated in the GSM Engine.
Power is also drawn from the Personal Computer to recharge the
LiIon battery. The power for the USB interface device (U6 on the
circuit diagram) is taken from the USB connector. This minimises
the current drawn from the LiIon battery to extend the operational
time between charges. Interface components (U4 and U5 on the
circuit diagram) isolate the connections between the USB device and
the GSM engine when either the USB port is disconnected (USB device
powered down) or the GSM engine has been turned off. A protection
device (U7 on the circuit diagram) has been included on the USB
port to protect the USB device from electrostatic discharge onto
the pins of the USB connector.
[0142] External Sensor Inputs (IN1-4 Signals on the Circuit
Diagram)
[0143] The prototype ISU device implements 4 external sensor
inputs. These connections are available on a dedicated input
connector (J2 on the circuit diagram) and on the special attachment
connector (J4 on the circuit diagram). These inputs have been
configured to allow external sensors to simply connect these input
signals to a 0Volt return signal (available on both connectors)
using a relay contact closure. This is the typical output from a
wide range of sensors.
[0144] An interface component (U3 on the circuit diagram) is
provided to isolate the input signals from the GSM engine when the
GSM engine has been turned off. There are also some protection
devices (D2-5 on the circuit diagram) to protect the inputs of the
interface component from electrostatic discharge onto the pins of
the connectors.
[0145] Controlled Outputs (OUT1 and OUT2 Signals on the Circuit
Diagram)
[0146] The prototype ISU device implements 2 controlled outputs.
These outputs allow external devices to be switched by the ISU
device. These outputs are implemented using transistors Q1 and Q2.
The connections to external devices can be made either by the
dedicated output connector (J3 on the circuit diagram) or the
special attachment connector (J4 on the circuit diagram).
[0147] Special Attachment Connector (J4 on the Circuit Diagram)
[0148] A special attachment connector has been provided on the ISU
device to allow it to be plugged into purpose built sensors. These
sensors will be engineered to accommodate the ISU device and all of
the required connections between the two devices are made through
the single attachment connector. This connector supports
attachments that are self-powered and are capable of providing
current to recharge the battery in the ISU, as well as attachments
that do not have their own power supply and require current from
the ISU device's battery to operate.
[0149] The apparatus of a monitoring system may include a number of
standard sensor devices available for purchase along with, or in
addition to the individual signal unit 22. Each sensor device is
adapted to respond to a predefined stimulus, and may include
sensors for power status, smoke detection, motion detection, door
or window opening, button press, fluid level, tampering, location
via the GPS system and video camera, for example. These standard
sensor devices are provided as a simple plug-in to the individual
signal unit 22, via one of the input connection 64 or USB port
shown in FIG. 4, or other standard interface ports provided on the
device.
[0150] An individual signal unit 22 may further be provided with
internal error monitoring facilities, such as a power supply
failure. Preferably also, individual signal units 22 are equipped
with interference sensors to alert the central control facility 12
of tampering by unauthorised persons, or disturbance by animals for
example.
[0151] Individual signal units 22 in at least one preferred
embodiment, are provided with output relays to activate one or more
external devices according to pre-programmed responses to sensor
monitored events. Examples may include the activation of audio
and/or visual alarms, the switching on of security lighting,
closure of fire doors and so forth.
[0152] The power supply and control module 42 is adapted to
maintain individual signal unit 22 in a passive, standby state
until receiving a signal from an external event sensor. Such a
signal initiates a powering up of the device, enabling it to
transmit its unique encrypted identifying code to the central
control facility. After transmission of this signal the individual
signal unit powers down and returns to its passive standby
state.
[0153] An individual signal unit 20 may also be brought into a
powered up state on command from the central control facility 12.
This powering up may be for the purpose of reprogramming the
individual signal unit 22 to install a new response procedure, for
example after the installation of a new, or an additional external
event sensor, relocation of the unit, or to modify an existing
procedure.
[0154] Where an individual signal unit 22 is provided with data
entry and display facilities, such programming or reprogramming of
the unit may be performed at the device itself. At the conclusion
of such local data input, the new or modified data is transmitted
to the central control facility to update its responses to any
signals received from the individual signal unit as required.
[0155] Referring again to FIGS. 9 and 10, during a powered up
state, as well as following any pre-programmed procedure for the
activation of any local connected devices, individual signal unit
22 will transmit a signal via the network 21 and a satellite 20,
reporting the event to the central control facility 12.
[0156] In a first simplest preferred form of the invention, a
signal sent by an individual signal unit 22 consists solely of its
unique encrypted identifying code. No data is sent with this code.
The information as to what a receipt of this code by the central
control facility means, is stored in the central processing
computers of the facility. This information, which is supplied by
and under the control of the registered owner of the individual
signal unit, may include instructions as to what actions are to be
taken in response to the signal.
[0157] Although in this preferred form of the invention, the
individual signal unit 22 is only enabled to transmit a single
encrypted identifying code, it may do so in various ways to
indicate various events. Each external event sensor is associated
with a unique sequence of repeat transmissions of said unique
identification code. For example if an external sensor device is
activated, the code may be transmitted a predetermined number of

an error condition develop in the device itself, such as for
example a low battery situation, the code may be transmitted
singly. The manner of transmission of this single encrypted code is
then the determinant of the status of the device and of what action
should be taken by the central control facility.
[0158] According to its pre-programmed instructions, an individual
signal unit 22 may continue to transmit its signal at intervals for
a pre-defined period as an aid in location of the device by service
personnel alerted by the central control facility 12 as described
below.
[0159] Again with reference to FIGS. 9 and 10, a received signal is
acted upon by the central control facility 12, notifying any of a
number of nominated recipients 30 according to a pre-established
protocol negotiated between the registered user of the individual
signal unit 22 and the control facility. Notification of details of
a monitored event could be made in the form of an email via the
Internet 29 as shown in FIGS. 9 and 10, by facsimile transmission
or over the distributed network 21 to any personal communication
device.
[0160] Typically, one nominated recipient 30 will be the registered
user or owner of the individual signal unit from which the alerting
signal was received. However nominated recipients may also include
service providers, who are automatically notified of the occurrence
and the nature of the event, the location of the individual signal
unit and any other pre-defined details. Service providers may
include police, fire and ambulance services, or equipment servicing
personnel for example. At registration of an individual signal
unit, the owner of the unit may elect that third parties be
contacted only on receipt by the central control facility of
authorisation from the owner.
[0161] An applicant user or owner will be required to supply all
relevant details of the individual signal unit, its external event
sensing faculties, intended location and the procedures to be
implemented on receipt of a signal from the device. The central
control facility then issues the unique identification code for the
individual signal unit. Alternatively, an individual signal unit
may be pre-programmed at manufacture with its unique identifying
code. As well, the applicant user or owner nominates a service
provider of the GSM, GPRS or other communication system, for
billing purposes, or alternatively, the central control facility
makes this arrangement, with billing for such service included in
the overall charge for use of the system.
[0162] The information thus received is used by the central control
facility to program the procedure to be followed by the facility in
response to signals received from the individual signal unit. The
facility may also transmit data to the individual signal unit prior
to its commissioning but subsequent to its installation at the
infrastructure item, to set the parameters of signal transmission,
such as frequency and interval of repeat transmissions for
example.
[0163] In Use
[0164] The signal unit 110 of preferred embodiments of the
invention thus provides considerable flexibility in the management
of electrical power particularly mains power derived from power
outlets in a domestic or industrial context. For example it may
afford micro management of an office environment where for example
signal units installed at every workstation detect that only one or
a small number of personnel are at work in the office. It can then
arrange modification to power use through adjustments to lighting
and air conditioning for example. Air conditioning settings
moreover can be monitored and adjusted according to data provided
by the ambient temperature monitoring module of the unit.
[0165] Power monitoring of individual devices is afforded by the
signal unit, so that for example the power usage of a television
set can be profiled over time to gauge its power consumption and
provide data for more efficient use of the appliance. Such data on
power usage of various appliances may lead to modified use or
replacement of a device in the interest of lowering power
bills.
[0166] The signal unit may detect that the temperature in a room is
above or below that of a desired set temperature and take
appropriate action by signalling adjustments to either air
conditioners or heaters as appropriate.
[0167] A movement sensor may detect no movement in the vicinity of
the unit for a given period of time and so switch off power where
appropriate.
[0168] In one form the plug-in, pass-through power sensor 110 with
wireless communications has the following capabilities: [0169] a)
240V plug on the back, socket on the front, suitable for standard
wall outlets, [0170] b) Measures accurately down to at least 100 mA
current, [0171] c) Continuous voltage and current, power factor
measurement, [0172] d) PIR, [0173] e) Ambient light, [0174] f)
Temperature, [0175] g) Humidity, [0176] h) Ability to switch the
load on or off remotely and, [0177] i) Periodic wireless reporting
of sensor information (limited by radio/network congestion).
[0178] The ISU Base Unit may include the following capabilities:
[0179] a) Ability to wirelessly receive data from up to 25 power
sensor units and forward the data to a server for processing
[0180] The intelligent database functions to support the unit 110
may require: [0181] a) Managing connection and allocation of
sensors to ISUs, [0182] b) Controlling reporting frequency, [0183]
c) Maintaining location and user identification information against
each sensor and therefore each measurement, [0184] d) Reporting
individual or groups of sensor data as a web service feed (in JSON,
XML or as required) for use in either external web pages or for
storage in an external database, [0185] e) Allowing control of the
power switch on each sensor unit by accessing a web service URL,
[0186] f) Providing a "Google Gadget" style dashboard for each user
which will allow display of current readings, historical graphs as
well as push button control of the power switch. Dashboard is user
configurable and operational via any web connected service (for
example, PC or mobile phone), [0187] g) Providing a facility to
trigger actions based on simple expressions of sensor data values
(Events). Actions include Email, IM or SMS messaging, calling a Web
URL or control of the power switch on the sensor. Events and
Actions are configurable per user via a web interface.
[0188] In particular forms the characteristics of the wall mounted
unit in the form of a "microhub" in communication with the ISU may
include the following: [0189] A micro hub to the ISU or other hubs
e.g. smart metering (were power is being monitored by the smart
meter we aim to provide a specialised device to compliment the
utility data as well as the ISU). [0190] Enables but not limited to
the micro management of office environments e.g. rather than air
conditioning an entire floor, especially when there may only be 1
of 100 staff members working, specific individual personal
temperature requirements or power usage can be configured and
reconfigured using the ISU or existing proprietary hardware to
control the device. [0191] Other units may provide power control
and monitor but using open hardware architecture the current model
is not proprietary control constrained. The hardware provides
multiple senses to enable the full environment sensory capability
so actual power relative to environment is achieved: [0192] Is the
TV overheating the room? [0193] Is the wall heater clashing with
the air conditioner? [0194] What device is attached to the wall
unit, profile the data? e.g. LG TV, provide data to others for the
actual real-time user costs and advertising of device relative to
other profiled TV i.e. this Samsung TV costs on average $300 a yr
less to run. Provide data to retailer for promotional rebates etc.
[0195] No movement near wall plug turn power off, apply logic . . .
track my phone. Track a localised RF transmitter fob, etc [0196]
The wall unit is price sensitive so high volume production may
enable each unit to have full transmission to the ISU system over
internet i.e. a micro ISU. Current versions focus on enabling the
data to be transmitted to the ISU as cost effectively and as
valuably as possible. [0197] Power usage can be controlled at
multiple levels of hierarchic [0198] Current plug-in, pass-through
power sensor measures accurately down to at least 100 mA
(theoretical accuracy is well down into the noise in single
digits), measures voltage and current several hundred times a
second, can account for and report voltage and current phase
relationships (and therefore power factor), can support a PIR,
light sensor and temperature sensor on board and supports modular,
pluggable radio modules, humidity. [0199] Interacts directly with
the ISU or other device e.g. smart phone, smart meter which enables
data feed to our centralised CCF platform for distribution. [0200]
It enables full versatility for all environmental effects relative
to power consumption monitoring and control, [0201] Components are
removable and module is expandable dependent on specific
environment requirements. [0202] The same concept is planned to
enable other switches in future also and not limited to: [0203]
DC-safe guarding green power feeds for example the recent floods in
Brisbane had live solar feeds going straight into the Brisbane
river with no way of disabling the solar circuits [0204] The
control of three phase e.g. Hot water units. If there's nobody home
