Description
RELATED APPLICATIONS
[0001] This application claims priority to U.S. Provisional
Application Ser. No. 61/304,712, filed on, Feb. 15, 2010, which is
incorporated herein by reference in its entirety.
BACKGROUND OF THE DISCLOSURE
[0002] The following disclosure relates to energy management, and
more particularly to energy management of household consumer
appliances, as well as other energy consuming devices and/or
systems found in the home. The present disclosure finds particular
application to a device which controls operation of consumer
appliances, as well as other energy consuming devices and/or
systems, and acts as a gateway between a Utility company network
and the consumer appliances, as well as other energy consuming
devices and/or systems. The controller/gateway device to be
discussed below is at times called herein a Home Energy Gateway
(HEG).
[0003] Currently Utility companies commonly charge a flat rate for
energy, but with the increasing cost of fuel prices and high energy
usage during certain parts of the day, Utility companies have to
buy more energy to supply customers during peak demand.
Consequently, Utility companies are beginning to charge higher
rates during peak demand. If peak demand can be lowered, then a
potential cost savings can be achieved and the peak load that the
Utility company has to accommodate is lessened.
[0004] One proposed third party solution is to provide a system
where a controller "switches" the actual energy supply to the
appliance or control unit on and off. However, there is no active
control beyond the mere on/off switching. It is believed that
others in the industry cease some operations of certain appliances
during on-peak time.
[0005] Additionally, some electrical Utility companies are moving
to an Advanced Metering Infrastructure (AMI) system which needs to
communicate with appliances, HVAC, water heaters, etc., in a home
or office building. All electrical Utility companies (more than
3,000 in the US) will not be using the same communication method to
signal in the AMI system. Similarly, known systems do not
communicate directly with the appliance using a variety of
communication methods and protocols, nor is a modular and standard
method created for communication devices to interface and to
communicate operational modes to the main controller of the
appliance.
[0006] Home energy management (HEM) systems are becoming a key to
reducing energy consumption in homes and buildings, in a consumer
friendly manner. Existing HEMs are commonly placed in one of two
general categories: [0007] In the first category, the HEM is in the
form of a special custom configured computer with an integrated
display, which communicates to devices in the home and stores data,
and also has simple algorithms to enable energy reduction. This
type of device may also include a keypad for data entry or the
display may be a touch screen. In either arrangement, the display,
computer and key pad (if used) are formed as a single unit. This
single unit is either integrated in a unitary housing, or if the
display is not in the same housing, the display and computer are
otherwise connected/associated upon delivery from the factory
and/or synchronized or tuned to work as a single unit. [0008] In
the second category, the HEM is in the form of a low cost
router/gateway device in a home that collects information from
devices within the home and sends it to a remote server and in
return receives control commands from the remote server and
transmits it to energy consuming devices in the home. In this
category, again, as in the first, the HEM may be a custom
configured device including a computer and integrated/associated
display (and keypad, if used) designed as a single unit.
Alternately, the HEM maybe implemented as home computer such as lap
top or desk top operating software to customize the home computer
this use.
[0009] Both of the current existing types have significant
disadvantages due to higher consumer cost, low flexibility and
increased system complexity.
[0010] The first category requires a large upfront cost to the
consumer, because the cost of providing an integrated display on
the HEM very expensive. In addition, the electronics required to
drive the display is complex and expensive. Further, from a
consumer point of view, they are forced to add one more display
screen to their home in addition to the home computer, smart
phones, televisions and the displays on pre-existing home devices
such as thermostats, appliance displays etc.
[0011] The second category of HEM involves a substantial cost to
provide the server infrastructure and data transfer. In addition,
this type of HEM must be connected continuously with a remote
server otherwise energy data logging and energy saving commands for
the devices in the home will be lost during service disruptions. In
addition, this configuration requires connection to the Internet to
access and view data. Therefore this second configuration is very
limiting in areas where Internet penetration is very low
[0012] To be commercially practical a HEM should result in a
payback of less than a year for the consumer through energy
savings. Current HEM systems result in payback of about 3-5 years
at best. Therefore, since the standard life of an electronic device
is about 5 years, the consumer is never paid back for their
investment; as they will need to procure a new device before the
investment payback period is reached.
[0013] Key functions of a HEM include: [0014] Creates a network of
energy consuming devices within the home, [0015] Measures the
consumption of the whole home/building or individual devices,
[0016] Records and stores energy consumption information in a
database, and [0017] Enables consumer interface with all energy
consuming devices in a home to: [0018] view consumption data of
individual devices [0019] set preferences for operation of energy
consuming devices at different times during the day or at different
energy pricing levels [0020] control/program energy consuming
devices.
[0021] For a HEM to achieve its intended function, all energy
consuming, energy generating and energy measuring devices must
communicate with the HEM through a network. The network of energy
consuming devices usually employs a communication design which has
very low power and low energy with a high degree of reliability.
The data bandwidth required to support a network of energy
consuming devices is much smaller than the data bandwidth required
for the networking of consumer electronics products, which is
usually high bandwidth and high speed. The networking standards,
including the physical layer, networking layer and application
layers are optimized for the end use.
[0022] Consumers want to view and control energy consumption
information available thru the HEM, through a variety of consumer
electronic devices available in the home. To enable this it is
required that energy consumption and control information must be
easily transferrable from the networks of energy consuming devices
to networks of consumer electronics devices. In addition, consumers
are more used to interacting with consumer electronics devices. So
the consumer interaction data on a consumer electronics device
should be able to flow into the network for energy consuming
devices and to enable command and control of the energy consuming
devices.
SUMMARY OF THE DISCLOSURE
[0023] The device disclosed herein is a home energy gateway (HEG)
that enables all the key functions of the HEM described above, and
enables the flow of data between networks having different
physical, link, network, transport and/or application layers,
provides a lowest cost product to the consumer with the flexibility
to interface with the HEM from any consumer electronics product
already available in the home and/or replace any HEM in a home
energy management network.
[0024] The HEG is a single board computer with a variety of
communication interfaces combined with sufficient memory and
computing resources to enable energy management of a home or
building. This device does not have a dedicated display either on
the device or in the system. It transmits the data stored within
its memory to other display devices, to enable a consumer interface
to the HEG.
[0025] In one embodiment, the HEG hardware comprises of a single
board computer with the following specification: [0026] Samsung
S3C2450 32 bit RISC. Microprocessor ARM926EJS, 400 [0027] DDR2
SDRAM (32 MB) [0028] NAND Flash Memory for Embedded Linux & HEG
Software (16M13) [0029] NAND Flash Memory for Database Storage (16
MB)
[0030] The single board computer has three communication interfaces
with different physical, networking and application layers.
[0031] The HEG it has an Ethernet and Wifi interface with the
following specification: [0032] IEEE 802.11 big Wi-Fi [0033] WPA,
WPA2, WEP-40, WEP-104, 802.1x, PEAP, LEAP, TLS, TTLS, FAST [0034]
MAC Address Filtering [0035] 1011 00 Base-T Ethernet
Connectivity
[0036] This interface is referred to as the first interface or
first network throughout this document.
[0037] The HEG of one embodiment also has two Zigbee Interfaces of
the following specification: [0038] IEEE 802.15.4 Compliant 2.4 GHz
Wireless Interface [0039] Smart Energy Profile, Home Automation
Profile [0040] Transmit Power: 20 dBm, Receive Sensitivity.
0.about.-100 dBm [0041] AES128-bit Encryption [0042] Install Code
using 128-bit Oseas Hash Function [0043] ECC Key Exchange using
Certicom Certificates [0044] SEP 1.0 Security Requirements [0045]
CBKE ZigBee Link Key Security [0046] ZigBee Pro Feature Set
[0047] Other physical implementations are possible given the intent
of minimizing the cost and the number of devices in a consumer's
home. For example there are a number of devices in a consumer's
home that already have power supplies. At a simple level, the HEG
database and radios could be connected internally to a PC, Set Top
Box, Cable Modem, Tivo, Video Player, or other consumer electronics
device.
[0048] The base advantage of this to the consumer would be to
utilize an existing power supply and enclosure, thus reducing (or
not adding to) the number of devices in the home. Such
implementation would also reduce the cost of the device.
[0049] Additional economies could be taken advantage of by
utilizing resources provided by the device. By providing
communication over a standard interface, for example PCMIA, USB,
etc., the resources of the host could be shared with the
device.
[0050] For example when attached to WiFi router, neither a WiFi
radio nor an Ethernet port need be provided in the HEG, as the HEG
could share those services from the host. By hosting in a WiFi
router, the HEG can also take advantage of the external antennas,
power supply, etc.
[0051] When attached to a cable television, TiVo, or video player,
the HEG could take advantage of the devices wired connection to a
high resolution display screen, for example.
[0052] These additional embodiments of the HEG do not change its
function as described below or its inherent advantages to the
consumer of being low cost, taking advantage of existing displays
in the home, and storing data to avoid requiring an external server
to access their data.
[0053] Two Zigbee communication interfaces are provided so that BEG
can talk to two separate energy networks.
[0054] Using one Zigbee interface, (referred to as the second
interface or second network) the HEG communicates with the smart
meter network. This interface reads the smart meter, an
energy-metering device, and records the data in the database of the
HEG.
[0055] The HEG communicates to the devices within the home using
the other Zigbee communication interface (referred to as the third
interface or third network). Using this interface, the HEG reads
the consumption of the individual energy consuming devices and
records it in the database.
[0056] Utility communications such as price signals, demand
response signals and text messages are received through the second
interface, recorded in the database, and communicated to the
devices in the home through the third interface. The command and
control information of the energy consuming devices and their
response to Utility signals is received through the third
communication interface, recorded in a database, and communicated
to the Utility company via the second interface, the communication
being routed through the Utility smart meter.
[0057] The HEG can also be programmed to vary the response of
energy consuming devices to utility communication based on consumer
preferences. The consumer may, if desired, program the schedule,
mode of operation and create unique device response to utility
messages. This programming is communicated through the first
interface.
[0058] The stored events, energy data, utility messages and
consumer setting preferences are accessed also accessed through the
first communication interface, which operates at a higher bandwidth
and uses a consumer electronics friendly communication protocol.
For example, in some embodiments this communication could be over
Wifi or Ethernet.
[0059] The user interface is an application that resides in one of
the consumer electronics products in a home or the home computer.
These home devices communicate to the HEG through a predefined
communication protocol. The user interface may request specific
data from the HEG like historical electricity consumption
information and the HEG can push information to devices in the
Local Area Network (LAN), like price changes or utility messages,
with all communication exchanges occurring thru commands based on
this communication protocol. In addition, the energy consuming
devices can be controlled or interfaced through the HEG, the user
interface communicating with the HEG using this communication
protocol over the first interface and the HEG communicating with
the energy consuming devices with a low bandwidth protocol using a
different physical communication layer.
[0060] The term communication protocol refers to three aspects
language, transport, and session. The term language is defined as
what is used to communicate data or commands such as XML, JSON-RPC,
XML-RPC, SOAP, bit stream, or line terminated string. The term
transport is defined as the protocol used to deliver the data or
commands such as UDP, TCP, HTTP. Session is defined as terms such
as, the Device pushing data via a socket based connection, or the
Device sending data in response to being polled. Examples of data
being pushed are TCP socket streams, and examples of polling are
the restful create, read, update, and delete methods.
[0061] The HEG plays a key role for the Utility company in
registering and communicating with devices within the home. Typical
devices that have to work with the smart grid thru the smart meter
need to be registered with the smart meter. This means that for
every energy consuming device that is installed in a consumer's
home, the consumer has to contact the Utility and provide them an
install code to register the device, which requires time and
resources for both the Utility Company and the consumer. Once the
HEG is registered to the smart meter, the HEG then acts as a single
point gateway for the Utility Company. In this way all other
devices in the home are registered with the HEG and communicate
with the HEG. The HEG then summarizes device actions, responses and
status and communicates a single message to the Utility Company.
This saves resources and infrastructure for the Utility Company's
meter system as there is only one device communicating from the
home, rather than 10 to 15 devices receiving messages, which would
otherwise require a large amount of bandwidth.
[0062] With communication protocols in a home converging to common
standards, the HEG can also be used to network other devices within
the home and store data. For example it could monitor the health of
consumers living in a home. A bathroom weighing scale can be
enabled with a communication interface, and the weight of a person
can be automatically read off the HEG and stored in the data base
with a time stamp, every time a person steps on the scale. The
device could similarly read other health parameters like blood
pressure, glucose, temperature etc.
[0063] In the same way, energy and water consumption in a home is
an indicator of daily life in a home. It can indicate activity in a
home, the number of people in a home, the health of people in a
home, safety and intrusion in a home.
[0064] The HEG could also operate with home automation and home
security systems over open standards. This would coordinate the
devices trying to control lighting, pool pumps, and other devices.
They could also share information in new ways. The appliances could
act as additional occupancy or intruder detection systems. For
example, if the home security is in the away mode, and the
refrigerator door opens, this could be passed to the security
system, just like a motion sensor.
[0065] The HEG can also be provided as part of a HEG adaptor module
configured to utilize services/components of existing household
electronics. Accordingly, a home energy management device for
controlling a plurality of energy consuming devices in a home
energy management network comprises a host device having hardware
for performing at least one service, and a home energy gateway
adaptor module connectable to the host device, the home energy
gateway adaptor module including at least a home energy usage
database for storing data related to usage of energy consuming
devices in the home energy management network. The home energy
gateway adaptor module is configured to utilize at least one
service of the host to carry out at least one function related to
controlling the plurality of energy consuming devices.
[0066] The home energy gateway adaptor module can further comprise
a controller for controlling the plurality of energy consuming
devices. The home energy gateway adaptor module can also include a
communication interface for communicating with the plurality of
energy consuming devices. The communication interface can include a
wireless communication interface. The home energy gateway adaptor
module can be configured via the host device. The host device can
be a wireless network device, wherein the home energy gateway
adaptor module is accessible through the host device via a personal
computing device. The home energy management device can further
comprise a display associated with the host device for displaying
information from the home energy gateway adaptor module. The host
device can be at least one of a personal computer, a wireless
router, a cable television box, a satellite television box, and a
television. The home energy gateway adaptor module includes a
standard connector for connecting to the host device, which can be
at least one connector of the type NIC, PCMIA, PC-Card, USB,
Ethernet, RS-232 serial port, 12C, RS-485, and Firewire. The
services of the host include at least one of a power supply, a
processor, a radio, a display, a user interface and a wired network
connection, Zigbee radio, 802.15.4 radio, Wi-Fi radio, program
storage memory and combined or separate data storage memory, user
interface LEDs, reset button.
[0067] A home energy management device for use in a home energy
management system including a plurality of energy consuming devices
comprises a home energy gateway adaptor module connectable to a
host device, the home energy gateway adaptor module including at
least a home energy usage database for storing data related to
usage of the energy consuming devices, and being configured to
utilize at least one service of the host device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0085] FIG. 1 is an exemplary implementation of the energy
management system 100 according to the present application.
[0086] The main source of information flow for the home is shown as
smart electric meter 102 acting as trust center, coordinator,
and/or and energy service portal (ESP), and which is configured to
communicate with a home energy gateway MEG) 104.
[0087] It is well known that these functions of smart meter 102 may
be separated into different devices. For example, if the home does
not have a smart meter 102--so the electric meter functions only as
a meter to provide consumption information--other components can be
used to provide the additional capabilities. For example, homes
without smart meter 102, can have the metering functionality of
smart meter 102 replaced with a simple radio and CT configuration.
Also, there are devices that can be placed on the outside of the
meter to communicate its consumption by reading pulse counts or the
rotating disk of the meter. In this embodiment, smart meter 102 is
shown with an IEEE 802.15.4 (ZigBee) radio, but the meter could
also communicate by a number of other standards such as IEEE (Home
Plug Green Phy or Home Plug A V), among others.
[0088] FIG. 1 is a compute 106 (such as a desk top, lap top of
other computing device) attached to a modem/router 108, a common
manner of attaching computers to the internet 110. In FIG. 1, a
computer connected to the router by a wired IEEE 802.3 (Ethernet)
connection 111. However, it is to be appreciated the connection
could be made by other known connections such as an IEEE 802.11
(Wifi) connection, power line communication or power line carrier
(PLC) connection, among others. In one embodiment, the PLC
connection is made using an adaptor such as sold by Netgear or
other manufacturer for that purpose. Although a modem/router
arrangement is shown in system 100, it is not essential, and the
system would function for its primary purpose of monitoring and
displaying energy consumption information without them. In that
case computer 106 would connect directly to HEG 104 via a wired or
wireless connection.
[0089] A web enabled smart phone 112 is configured to connect to
HEG 104 for displaying data and configuring accessories (such as
home appliances 114a-114k), except that only a wireless connection
is available.
[0090] Accessories 114a-114k fall into two categories sensors and
devices (where, depending on how they are used, some accessories
fall into both categories). Examples of sensors include solar
meters 114a, gas meters 114b, temperature sensors 114c, motion
sensors 114d, and appliances reporting their power consumption
(such as dishwashers 114e, refrigerators 114f, stoves 114g,
washers/dryers 114h, etc.). Devices include thermostats 114i,
alarms 114j and simple switches 114k, along with the appliances
(e.g., dishwashers 114e, etc.), when performing their normal
functions. The foregoing are just some examples of accessories to
which the concepts of the present application will apply.
[0091] The HEG 102 is constructed with computational capabilities
and multiple communication technologies. In contrast to existing
controllers (such as an HEM) used in home energy systems, the
special purpose HEG 102 is significantly smaller, cheaper, and
consumes less power. The HEG 102 also has the capability of
operating over multiple communication networks, which allows HEG
102 to acquire and manipulate data of one communication network
(e.g., that which monitors/controls the home appliances) and to
supply that manipulated data to another communication network
(e.g., to the consumer electronics network, such as to a home
computer, smart phone, web-enabled TV, etc.), even though these
networks are not generally compatible. As another example, the MEG
102 is connected to system loads (e.g., the home appliances, etc.)
over one type of communication network, to the Utility company over
a different communication network, and to a display over a third
different communication network.
[0092] In one particular embodiment connection to the display is
via a WiFi communication network, connection to the Utility Company
(over the meter) is via a ZigBee communication network, and
connection to the home device/appliance network is over the third.
Alternatively, in a home where the devices and Utility Company's
rules are different, the data could be structured differently. For
example, the whole home consumption could be available over the
Internet (as it is in Allentown, Pa. pilot project), or via a
ZigBee meter on the second network. Further, in addition to the
display, several home automation devices including pool
controllers, emergency generators, and storage batteries are
designed to be accessed over Ethernet using Internet Protocol
(IP).
[0093] Turning to FIG. 2 depicted is a block diagram 200
illustrating one embodiment of the HEG 102. On the left hand side
of the figure outside of block diagram 200 is remote configuration
and data acquisition block 202 (which is not part of HEG block
diagram 200). The external data and remote configuration requests
are received into block 200 via WiFi radio block 204, which in turn
accesses energy and event database 206. The external data and
remote configuration requests of block 202 could also enter block
diagram 200 via Ethernet port 208 in order to access the energy and
event database 206. In still a further embodiment a power line
communication (PLC) adapter 210 (dotted lines) may be used with or
as an alternative to the Ethernet port 208, in order to input the
external data and remote configuration requests 202 into the energy
and event database 206.
[0094] On the right hand side of FIG. 2 is a first data interface
block 212 (such as a 802.15.4 Zigbee radio) and a second data
interface block 214 (such as a 802.15.4 Zigbee radio). The first
data interface block 214 is configured to send and receive data and
configuration messages to/from utility meter Zigbee network 216,
and second data interface block 214 is configured to send and
receive data and configuration messages to/from the internal HAN
(e.g., data from appliances in the system) 218. The data and
messages from these sources also connect to the energy and event
database 206, via internal HAN smart energy block 220. The database
functions will be covered in more detail later. In still a further
embodiment power line interfaces 222, 224 (dotted lines) may be
included with or as an alternative to the interfaces 212, 218.
[0095] FIG. 3 shows a more detailed hardware block diagram 300 of
HEG 102. Of specific interest is input/output (I/O) block 302 at
the bottom of the figure. The 110 block 302 consists of chip LEDs
304,306, and 308 which are used to convey network status for the
three individual networks of the HEG 102. The LEDs convey status
from off (no network), flashing (network available), to solid lit
(joined network) for each network. Optionally an additional LED
(not shown) may be provided to identify power availability. Also if
additional networks are incorporated into the HEG 102 an additional
LED may be add for the additional communication network. These
simple status lights allow a user to confirm the HEG is working. By
this design if there is an issue, a user may connect with an
display device for more detailed investigation of the problem and
to correct the Issue. Also depicted is a reset push button 312
which (as will be shown below) may be assessed by a user externally
on the HEG unit itself.
[0096] FIGS. 4A-4P illustrates various views of HEG 102. Not
requiring a display or input keys on HEG 102 allows the HEG 102 to
be configured in a very compact design. In one embodiment, this
results in the HEG having dimensions of
53(W).times.72(H).times.55(D) mm (2.09 (W).times.2.83
(H).times.2.16 (D) inches). With a depth (D) of 37 mm (1.45 inches)
minus the prongs of the plug. The volume of the HEG being 160 cm 3
and the weight of the HEG being 100 g. It is therefore small enough
to be plugged into a standard wall outlet, and does not need space
on a counter, tabletop and does not need to be attached to a wall
or other surface with screws or adhesive. Because it does not have
a separate display or keyboard, there are no wires to add to
clutter or get caught on items. Having the power supply embedded
and/or integrated in the HEG helps keep it small. It also allows
access to the power lines for PLC communication. A small power
supply can also be tuned to exactly the needs of the HEG, instead
of selecting from a standard plug transformer, and avoid the risk
of a consumer plugging in the wrong wall adaptor. The design also
includes additional flame retardant materials in the housing, and
securely attaches the outlet prongs to the housing.
[0097] FIG. 4C shows reset button 400 (corresponding to block 312
of FIG. 3) and Ethernet input 402 (e.g., 208 of FIG. 3).
[0098] Turning now to the setup of the HEG, the consumer will need
to configure HEG 102 to monitor energy consumption. Prior to
starting to commission the HEG, the consumer will need to load
specific Client Application Software (CAS) onto his computer or
smartphone. Typically this software would be downloaded over the
Internet or purchased from the phone provider. The software may be
a general purpose Java application that will run on any PC, or it
may be tailored specifically to the physical limitations and
operating system of the device, which is common in the cellular
phone business. Alternatively a Web CAS could also be used.
[0099] FIG. 5 is a flow diagram 500 which illustrates, for one
embodiment, the steps undertaken to achieve such configuration. An
expanded discussion of FIG. 5 is set forth in later sections of
this disclosure. After starting 502, a user connects to the HEG 504
by providing the HEG with power (e.g., plugging it into a home
outlet) and accessing the HEG via the CAS. The CAS allows the user
to provide the HEG with a name so it may be identified in the
network (see FIG. 6). Once connected, if there is a home wireless
network (such as WiFi) 506, the user may optionally connect the HEG
to that network 508 (see FIG. 7). Next, if the user has a home
Internet connection 510, the HEG can be connected to this network
512 (see FIG. 8). Once these steps are accomplished, the user
connects the HEG to the energy supplier (e.g., Utility company)
network 514 (see FIG. 9). Finally, the user connects the appliances
(and other systems) to the HEG 516 (see FIG. 10).
1. Connecting to the Device. (FIG. 6)
[0100] Turning now to FIG. 6, as mentioned above, a particular
beneficial aspect of the HEG 102 is the value and flexibility
obtained by not having a dedicated, integrated user interface
display. Not having such a display does require initial steps in
the configuration of the HEG into the home energy network (or HAN)
in order to connect the HEG to the network. These steps include:
[0101] a. Connect the HEG to its power source e.g., a common home
power outlet). This will power the LEDs (304-308) causing them to
light. [0102] b. Connect an Ethernet cable from computer to device
to Ethernet input (208), or attempt peer-to-peer wireless
connection (e.g., wireless input 204). [0103] c. Install software
on a smart phone, computer or other device capable of operating
software. [0104] d. Use the software which employs
zero-configuration networking (such as the Apple Corps Bonjour from
Apple Corp) to detect the HEG. Once the HEG is detected, the user
provides the HEG with a name and password to prevent others from
modifying their personal settings.
2. Connecting to Home Network (FIG. 7)
[0105] As mentioned above, step 508 of FIG. 5 is optional. However,
for homes with WiFi network and where the HEG is attached via an
Ethernet connection, step 508 is available. In this case, the
Ethernet cable would be disconnected and the HEG moved to an out of
the way home electrical outlet. By this action the consumer will
still have access to the HEG over their home network but the HEG
would not need a prime electrical outlet. If the HEG is replacing
an HEM or other type of controller which has a built in or
otherwise connected display and is therefore mounted on a wall for
viewing of the display, the HEG in the wireless environment would
of course not be mounted on a wall and could, again be, located in
an out of the way electrical outlet. If the consumer does not have
a home wireless network, they may continue to have the HEG
connected to a router to share their Internet connection or remain
directly connected to their computer if they do not have an
Internet connection. If connected over WiFi the WiFi LED on the HEG
will illuminate.
3. Connecting to Home Internet (FIG. 8)
[0106] This step is also optional, and is not required for the
device to work. No special configuration is required on the HEG.
Depending on the security implemented on the consumer's Internet
connection, some modification to their router and/or firewall may
be required. In some instances the use of the HEG may be
advantageous over a "Cloud Computing" model for home energy
control, as that the data storage for the HEG is local.
4. Connecting Energy Supplier Network (FIG. 9)
[0107] Connection steps for connecting in a typical smart meter
environment and for connecting in an Internet environment are now
described.
[0108] a. The following describes the steps to take for a typical
smart meter application. [0109] i. For a smart meter, either wired
or wireless, the HEG will connect to the smart meter over a second
network. The customer locates their install code that is displayed
in their CAS. Alternatively the install code can be written on the
HEG or supplied with its documentation. The customer then takes
that install code and depending on their Utility either enters the
install code into a browser window or they call their Utility's
Customer Service Center. [0110] ii. Also they will add identifying
information on the home that the HEG is in. Depending on the
sophistication of the utility network, they may need to enter their
address, account number off their bill, or they may need to call
and get a special code to identify them. [0111] iii. Once this is
complete, a command is sent from the CAS (e.g., of the software
added to the homeowner's computing device) to the HEG over the IP
Network to have the HEG start the joining process on the Utility
network. [0112] iv. Once the appropriate security has been
negotiated, the HEG will send a confirmation back to the CAS over
the first IP network to indicate that the connection has been made.
[0113] v. The HEG will also turn the Utility Network LED ON to
notify the customer that it is connected. This allows for the
customer to determine the state of the network just by glancing at
the HEG, without connecting an I/O device. [0114] vi. The HEM will
determine which of the devices on the Utility network is the homes
billing meter. Multiple devices could say that they are a meter.
[0115] 1. This is simplest if there is only one meter on the
Utility network, but there may be more (i.e., there may be
sub-meters). [0116] 2. Typically if there is a single device that
is a meter and a Utility Services Interface (USI), the source of
energy information (price load control commands etc.). That is the
billing meter, although in some areas there is a separate device
that acts as the Utility Services Interface (USI). [0117] 3. If
there are two devices that both are meters and neither is the USI,
the HEG has to dig deeper. For example a plug-in hybrid electric
vehicle (PHEV) charger could be on the Utility network as a meter
and as a load control device, so it could be turned off during a
grid emergency. Then the HEG would assign the one that is not a
load control device as the Utility meter. It is noted some meters
have disconnect switches installed inside of them, even in this
case, the utility typically does not provide control of that switch
to the HAN, but only on its backhaul network. [0118] vii. Any
devices that are found by the HEG that are not the Utilities
(revenue) meter are saved for configuring as part of the home
network.
[0119] b. For Internet based energy supplier information. [0120] i.
In this case the install code will typically not be required, since
the Utility network is not being used. The customer will start by
entering identifying information on the home that the HEG is in
into a CAS window. Depending on the sophistication of the utility
network, they may need to enter their address, account number off
their bill, or they may need to call and get a special code to
identify them. The may also have to enter a specific URI that
indicates where to get the pricing information. [0121] ii. Once
this is complete, an XML message command will be sent from the CAS
to the HEG over the IP Network to have the HEG contact the utility
information page over the internet. [0122] iii. Once the
appropriate security has been negotiated, the HEG will send a
confirmation hack to the CAS over the first IP network to indicate
that the connection has been made.
5. Connecting Appliances to Network. (FIG. 10)
[0123] Typically appliances will be installed on a second network
that is entirely maintained by the homeowner. The ZigBee network is
used for this purpose in the exemplar, but that is not critical to
the invention. Some devices, such as a Thermostat, or PHEV charger
may be tied directly to the Utility network in the same manner as
the HEG, if for instance, the PHEV qualifies for a different rate
or the customer is getting a credit for allowing the Utility to
control their HVAC. In this case the consumer can skip directly to
step vi. [0124] i. The customer will enter the install code of the
device into a CAS window; the CAS will then transfer this message
to the HEG over the first IP network. [0125] ii. The HEG will
create the third network and look for a device that is attempting
to join. The third (3.sup.rd) network LED will flash. [0126] iii.
The customer will then be asked to press a button or take similar
action on the device to tell it to join the network. The precise
action to take is dependent on the devices instructions. [0127] iv.
The HEG will exchange security information over the third network
with the device and compare it with the information received over
the first network. If the information indicated the device is to be
trusted, it is let onto the network. In this case the third
(3.sup.rd) network LED will be lit. [0128] v. The HEM will detect
that there is a device on the network and will gain basic
information about the device. The device will provide some
configuration data, for example that it is a washer, a water
heater, or that it is a load control device or a meter. [0129] vi.
The HEM will bring up a list of devices that it has found. For ease
of identifying the devices, it is easiest if the consumer adds all
the devices individually and fills in the identifying information
on each as it is found. The consumer can also add a user-friendly
name to his device at this time to make it easier to identify in
the future. [0130] 1. For a device with a device type of appliance,
the consumer may need to add a name like refrigerator, or dryer.
[0131] 2. If there are multiple thermostats, the consumer may label
one as upstairs and one as downstairs so that they can control them
independently. [0132] 3. Some devices will be added just as a
meter. For example one such device may be a meter on a solar or
wind generation panel. The customer will have the opportunity to
select the identity of the device from a list. Based on this
selection the HEG will identify the device as a load or source.
This is important later when creating reports, because loads are a
subset of the revenue meter, but the sources are additions to the
revenue meter. [0133] 4. Storage batteries will need to be
identified as such so that the HEM can read a field to indicate
direction of power flow. While current standards have this field as
optional, it is assumed that a storage device would support it.
[0134] vii. The above steps can be completed as many times as the
consumer desires, to add all of the devices they desire to the
network. In addition to devices mentioned above, a whole host of
home automation devices can be added, including but not being
limited to motion sensors, door sensors, lighting controls,
switches, smart plugs, bathroom scales. Anything which can function
by turning on/off, adjusting up or down, or provides information on
the amount of something can be easily integrated into the data
structures of the HEG.
6. Connecting to an External Server.
[0135] Just because the consumer does not have to use a
cloud-computing device, does not mean that it cannot be done. For
example, Google Inc. has a Google Power Meter (GPM) service. On the
consumers CAS, they could select connect to GPM, and the data could
be ported to the cloud server. Either the consumer or the cloud
server may select only to accept a portion of the data. For
example, the consumer may select to pass the utility power meter to
the cloud server, so he can access it from work, or the cloud
server may limit the consumer to two devices with 15 minute
increments between points.
7. Connecting Zighee Device
[0136] Numerous commercial devices are available for measuring and
controlling plug loads and larger loads, as well as ZigBee home
automation for controlling lights, security and comfort. One such
example is the ZBLC30--Dual (30/15A) Relay with energy meter. This
ZigBee 110/220V Dual-relay (30/15A) describes itself as a
controller with energy meter which remotely controls high current
heavy loads such as water heaters, pool pumps, pool heaters,
electric vehicle charges, air conditioners, etc. Using the wireless
ZigBee protocol allows the switch to constantly measure the power
delivered to the load and report various parameters such as real
and apparent power based on high accuracy industry standards. This
makes possible the intelligent management of large appliances.
Provided with both normally open (NO) and normally closed (NC)
contacts for maximum flexibility including fail-safe
configurations.
8. Connecting an External Device.
[0137] There are numerous devices available to consumers which have
Ethernet or WiFi capabilities. For example a Pentair pool
controller from Pentair Water Pool and Spa, or an alarm system
controller from Smart Home, are just two examples.
[0138] By use of a special purpose application program "APP" these
and other such devices can communicate with the consumer's energy
management system so that they can make adjustments to all of the
systems in one place and set their own priorities. These apps are
loaded by the same update program which manages the HEG
software.
[0139] Turning now to the operation of the HEG, set out below are
examples of various data flows which can be obtained by use of the
HEG.
1. Power Consumption Data from Meter to Database. [0140] a. HEG
sets up a timer. [0141] b. Periodically pings meter for consumption
on 2nd network. [0142] c. Stores consumption data in data base.
2. Price Signal to an Appliance Using.
[0142] [0143] a. HEG receives a price schedule or price change from
Utility over 2nd network. [0144] b. HEG stores price data in table
in memory for future use in calculating cost reports. [0145] b. HEG
reviews scheduling priorities received from consumer over 1st
interface. [0146] c. HEG sends load shed command to appliance or
system (e.g, pool pump disconnect box) over 3rd network.
3. Utility Direct Load Control Command to Load Control Box on a
Pool Pump.
[0146] [0147] a. HEG receives a price schedule or price change from
Utility over 2nd network. [0148] b. HEG reviews scheduling
priorities received from consumer over 1st interface. [0149] c. HEG
sends load shed command to pool pump disconnect box over 3.sup.rd
network. 4. Power Consumption from a Smart Appliance to Database
[0150] a. HEG sets up a timer. [0151] b. Periodically pings meter
for consumption on 2nd network. [0152] c. Stores consumption data
in data base.
5. Daily Power Consumption Cost Chart to Hand Held Device. (FIG.
11)
[0152] [0153] a. Handheld contacts HEG over 1st Interface (WiFi),
sending scripted request for data. [0154] b. HEG reviews database
and assembles data requested. Either the HEG could retain cost data
in a single table, or it could pull consumption and price data from
separate tables and combine into cost data. [0155] c. HEG formats
data for report using open scripting commands such as [0156] d. HEG
sends requested information to Handheld over 1st interface. 6.
Power Consumption Data from HEG to External Server. [0157] a.
Consumer sets up conditions for transmitting data to external
server over 1st interface. [0158] i. Consumer selects server from
list or types in URL [0159] ii. Consumer selects how frequently
data is to be ported [0160] iii. Consumer selects which data is to
be ported [0161] b. HEG sets up timer to meet consumers request.
[0162] c. HEG assembles the subset of data requested by the
consumer and formats for transmission on Internet. [0163] d. HEG
posts data to webserver that consumer has selected. 7. Message from
Utility to Computer Display. [0164] a. HEG receives text message
from Utility over 2nd interface. [0165] b. HEG reviews instructions
from consumer on where Utility messages should go (Computer screen,
Thermostat Screen, TV Set, Hand Held, Dedicated energy display)
received over 1st interface. [0166] c. HEG formats message
appropriately for Interface and pushes message to appropriate
display device.
[0167] Once the consumer has the HEG connected to meters and
devices and collecting data they can start to take advantage of its
capabilities. A particular benefit of this system, which uses the
HEG without a dedicated or integrated display, is the ability to
use a high quality display to view data and interact with
appliances without having to pay for it separately. Many consumers
already have large displays of 17'', 35'', even 52'' diagonals that
they use for entertainment systems. Many of these devices already
are provided with Web CASs. Accessing the electricity consumption
of a home on a TV screen will provide a more readable display of
their consumption habits to the consumer than the small monochrome
in-home displays that Utilities have been using in pilots. In
addition being able to look at the change in energy consumption
when you turn on a range or dryer, the present design provides
consumers with an increased awareness of where there energy dollar
is going. Because the consumer displays (e.g. TVs, computers, smart
phones) are adapted to graphical display, they are well suited to
display this type of information.
[0168] This improved interface also allows the consumer to fine
tune their response for different appliances with more detail than
was possible over a typical appliance control screen. This
customization can be done either in conjunction with energy prices,
weather information, time of day, occupancy or other external
parameter, or just as a user defined rule without any outside
parameters.
[0169] A first example: A dishwasher cycle is delayed because of
high energy costs. However the water heater is not heating either.
The HEG provides the consumer with the option of waiting until the
water heater has caught up before starting the dishwasher.
[0170] Another dishwasher option: The consumer can determine to not
allow (or always require) heated dry, extra pre-washes, or extra
heat on a dishwasher at any time, despite what is selected at the
controls of the dishwasher. This feature may be valuable for people
whose children are assisting with meal clean up.
[0171] A second example: The consumer starts their dryer in a delay
start mode, but before the delay time is completed energy price
goes up. The consumer will be asked if they still want the dryer to
start when scheduled.
[0172] An additional dryer example is to limit the maximum heat
regardless of the energy level selected. This balance of saving
energy at the expense of drying time could be made at any time, or
could be done to prevent children or spouse from damaging garments
by drying at too high a temperature.
[0173] An example of using weather is to prohibit dryer operation
when the external temperature was above 80 degrees to avoid
competing with the air conditioning, or to prohibit dryer use if
the sun was shining and line-dry clothes instead.
[0174] A third example: The consumer can automate the decision for
which of various modes he would like his water heater to operate
in. Depending on the water heater, the modes that can be selected
from include: Electric Resistive Heaters Cal Rod, Electric Heat
Pump, Gas, Solar, and Off. He can use electric price, weather, gas
price and home occupancy to select from.
[0175] A washing machine example. The consumer could use this
feature to control which temperatures can be selected, or prohibit
using the washer at certain electric costs.
[0176] The improved user interface is also an advantage when
programming devices. Programmable thermostats are often hard to
program via their limited user interfaces. For example, you have to
push the menu button twice, then the left button, then the down
button to set the hour, then the left button, until a full schedule
of 7 days with 4-6 events per day have been loaded. The user
interface on the HEG with a computer or smartphone can display it
graphically. Because the consumer is familiar with the interface,
the commands are more intuitive. They can drag and drop changes of
times, and copy and paste of one days schedule to a different day.
Once they are happy with the schedule, they can save the whole
schedule and then send it to the HEG over a high data rate
Ethernet/WiFi connection. The HEG will save the schedule
internally. A customer can build a number of schedules. Winter
(Heating), Summer (Cooling), Summer Vacation (Home empty, cool just
slightly, circulate outside air at night); Summer Kids Home (Cool
During the day) etc. After the customer selects one to load, the
HEG loads the schedule to the thermostat. Thereafter the customer
can change schedules and return to the original schedule without
needing to reenter information.
[0177] Turning now to FIG. 12 shown is an example of the data
portion of a message payload that could be used to send a schedule
to a thermostat. Appropriate headers and checksum fields can be
added based on the exact communication protocol established.
[0178] The row Bytes is the size of the field. The Data Type and
Field Name describe the type of data in each field. The schedule
consists of a series of Transition times, high set points, and low
set points. Each set point is scheduled to be in effect until the
next transition. The variable field can contain multiple
transitions until a final (nth) transition for a given day. At
midnight the schedule will continue the prior days last transition
until the first transition of the new day. The Day of Week field
identifies the day that is being scheduled. Where Day 0 is Sunday,
Day 1 is Monday, Day 2 is Tuesday etc. Alternatively a bitmap field
could be used to set the same schedule into multiple days
simultaneously. The variable field can contain repeated
Transitions.
[0179] The example of a thermostat programming is not limited to a
thermostat, but could be included with anything that normally runs
on a schedule. A different example could be a pool pump and spa
controller, where high set point is spa temp and low set point is
the pool temp.
[0180] Another application is setting pool pump run times, where
the high and low set points can be set at 0 and 100 to control off
and on. A variable speed controller could use 1-99 to indicate a
percentage of full run.
[0181] This on off scheduling could also be used with a water
heater controller so it would not maintain water temperature when
the homeowner is scheduled to be at work.
[0182] The HEG relies on a number of different software sets. There
is software on the HEG itself. There is a second piece of software
on the desktop or laptop computer used to configure the HEG and
gather data from it. There is a third piece of software on the
smart phone. The phone and computer may be further defined by the
operating system, or may take advantage of a platform like Java
that allows the programs to operate on multiple operating systems.
Each of these can be upgraded independently of each other. The
desktop (or laptop) and smart phone Apps also have a service for
the HEG. They can ping a server (e.g., if from General Electric, a
GE server) every day checking for the latest software release. As
new software becomes available, either to correct issues or add
features, they can down load the newest HEG software and the push
it down to the HEG. This way the software sets can be upgraded
independently of each other.
[0183] Once the HEG knows which appliances are on the network, it
can also check the server for updates for those devices, and
download that software if needed.
[0184] In addition, the present system allows for provisioning
(i.e., preparing the system to accept new services) whereby special
purpose software can be downloaded. When the customer buys a new
washer, and enters its model. The software can contact the GE
server, and be given an app to download. This app allows the
consumer to set more detailed control of the appliance. It would
know for instance this particular washer has five wash
temperatures. It would then provide the customer with the
opportunity to customize their wash experience. For example the
customer could set the washer to not ever allow sanitation cycles
and only allow hot wash when electric prices are at or below a
threshold price (e.g., <$0.15 a kWhr). Alternatively the
customer may decide that since they are on a gas water heater, the
HEG should not control water temp when electric price changes.
Another function that the washer could have is a delayed start
feature. If the washer is in the delayed start, the customer could
(through the HEG) either tell the washer to start now, or to delay
its start even longer.
[0185] An example of passive operation of the HEG is the monitoring
of a dryer. The HEG can notice that the dryer says it is in high
heat, but never goes over 3 kW. If this occurs on a single occasion
this may be a loading or airflow condition, but if it happens
repeatedly, it may be a failed open heater. In a more active role,
the HEG could ping a dishwasher, and ask it for all of its error
codes. The HEG can then send that information to the dishwasher
manufacturer, either automatically or upon the customer's request,
or make it available to the customer on a display when they call
for service, thereby assisting the manufacturer in troubleshooting
the unit. Alternatively, the customer could download more detailed
analytical software if they were having issues with a specific
appliance that could run diagnostics on the appliance and sends the
results back to the manufacturer so the technician could arrive
with the correct part.
[0186] In addition to monitoring for service, the monitoring
software can also keep the consumer up to date on the status of
their home. For example the time remaining on an oven self-clean,
the end of cycle on a dishwasher, or the current hot water tank
temperatures could be communicated to the HEG by appliances over a
the low bandwidth third network. This info can then be sent to the
consumer via the first interface to a WiFi enabled smart phone or
Web enabled television, or possibly a Bluetooth device. It could
also be sent to him outside of the hoe by email, SMS text message
or similar method.
[0187] Another option during provisioning is to download a software
set that customizes the display so that it essentially duplicates
the features of the appliance, but uses large font and improved
colors for people with poor visual acuity. People with vision
impairment could use a 17'' screen with black numbers on a yellow
background to set the temperatures on the refrigerator or schedule
the self clean on an oven.
[0188] Other special purpose software may be offered in conjunction
with a Utility company. The customer may have a special code from
their Utility company which downloads a software set that tracks
air conditioner thermostat setpoints and passes that information
back to a Utility company server. The customer then gets a bonus
for maintaining certain target temps, and by not overriding
setpoint changes during grid emergencies.
[0189] Another set of specialty software is for commercially
available devices. If the customer buys a device from a third
party, they can log on and download the software that blends that
device into their network. It may be lighting controls, the pool
controller mentioned earlier, or a third party thermostat.
[0190] Turning now to FIG. 13, a home energy management device 700
is illustrated wherein an HEG module 704 shares one or more
services with a host device 708. The host device 708 includes
hardware for performing at least one service, such as a display
712, an input device 714, a power supply 716, a Wifi or other
wireless communication radio 718, an Ethernet connection 720,
and/or one or more communication ports 722, such as a USB port,
serial port, etc. As will be appreciated, the host device 708 can
provide virtually any service depending on the type of device.
Examples of residential host devices include a wireless router, a
personal computer, a cable television box, a satellite television
box, a television set, a smart phone, purpose-built devices, an
internet tablet, a book reader, or a combination thereof. Virtually
any device that is capable of communicating with the HEG module 704
via a wired or wireless connection can be a host device for the
purposes of this application.
[0191] The HEG module 704 in the illustrated example is connected
to the port 722 of the host device 708. This port could be, for
example, a USB port of a home computer or cable box, or an Ethernet
port of a wireless router. In this regard, the HEG adaptor module
708 can be essentially a USB storage device such as a "jump drive,"
or the like. Such HEG adaptor module 704 includes a home energy
usage database 730 for storing information related to the home
energy network and/or algorithms for controlling one or more device
within the network. A communication interface 734 can also be
provided for communicating with one or more energy consuming
devices in the network. As will be appreciated, a wide variety of
hardware and/or services can be provided on the HEG adaptor module
as well.
[0192] With reference to FIG. 14, an exemplary physical embodiment
includes a wireless router 802 as a host device, and a HEG adaptor
module 806 connected to an Ethernet port 812 of the wireless router
802. The wireless router can be any typical wireless router and
generally will include an 802.11x wireless radio (or the like) and
circuitry for creating/maintaining a wireless network of devices.
The wireless router 802 typically will include its own power
supply, and will often be used in conjunction with a modem or other
device that provides internet connectivity to the wireless
router.
[0193] The HEG adaptor module 806 generally includes memory for
storing a home energy usage database, and a communication interface
for communicating with one or more energy consuming devices. The
HEG adaptor module 806 is configured to utilize one or more
services of the wireless router 802 including, for example, a power
supply, an interne connection, the wireless network, etc.
[0194] As will be appreciated, once the HEG adaptor module 806 is
connected to the wireless router 802, various features of the HEG
can be accessed from another device on the wireless network. such
as a personal computer 816 as shown, or a mobile phone having Wifi,
a cable box, etc. The personal computer 816 in the illustrated
embodiment includes a CPU 818 connected to the wireless router, a
display 820 and a keyboard 824. The personal computer 816 can be
configured to access the HEG adaptor module 806 through the
wireless router 802 and display a user interface on its display
820. In this manner, a user can view information stored on the HEG
adaptor module 806 and/or configure various aspects of the HEG
adaptor module relating to the control of energy consuming devices
in the HEM network, in accordance with the manner described above.
In this regard, the router 802 and personal computer 816 together
can be considered the host device, since services of each are
utilized by the HEG adaptor module 806.
[0195] Turning now to FIG. 15, another HEG adaptor module is
illustrated in the form of a universal serial bus (USB) adaptor
module 902. The USB HEG adaptor module 904 includes a male USB
connector 908 for connection with a USB port of a host device, and
a housing portion 912 including at least a memory device for
storing a home energy usage database. The USB HEG module can
further include a communication interface, such as a wireless
networking device, for communicating with one or more energy
consuming devices in the HEM network as described previously. The
USB HEG adaptor module can be configured to be plugged into a USB
port of a home computer, cable box, wireless router, etc., in order
to provide the functionality set forth above.
[0196] Turning to FIG. 16, another HEG module is illustrated
installed under glass in a smart meter 1000. In this embodiment,
the HEG module is in the form of a PCMIA card 1004 configured to be
installed in a corresponding PCMIA slot 1008 provided in the smart
meter 1000. AS will be appreciated, the smart meter 1000 acts as
the host device and the PCMIA card 1004 (HEG module) utilizes at
least one service of the smart meter 1000 to carry out one or more
functions as previously described.
[0197] In FIG. 17, another exemplary embodiment is illustrated
wherein a PCMIA card 2004 is installed in a set-top box 2008, such
as a cable box, satellite receiver, entertainment PC. etc., on top
of a display 2012. As will be appreciated, the PCMIA card 2004 is
installed in a corresponding PCMIA slot (not shown) in the set-top
box 2008. The PCMIA card 2004 (HEG module) utilizes one or more
service of the set-top box (2008 (host) to carry out one or more
functions as previously described. This can include using the
set-top box's power supply, internet connection, WIFI, connection
to the display 2012, etc.
[0198] As will be appreciated, the HEG adaptor modules as described
above utilize services/components of existing home electronics and,
thus, such components/services need not be provided with the HEG
adaptor module. For example, the HEG adaptor module obviates the
need for a dedicated a display, input device, power supply, etc.
This results in a device that is much less expensive to produce and
therefore reduces the cost to a consumer of adding a HEM network to
the home.
