BACKGROUND OF THE iNVENTION TECHNICAL FIELD The invention refates to the monitoring and control of household appliance. More particularly, the invention relates to a smart-grid having PLC networked sensors.

DESCRIPTION OF THE BACKGROUND ART

Communication using power fine has been limited, until recently, to a few local area networks (LANs) within homes or offices or, at best, within apartment complexes. Power line communication has also been used in a limited number of applications where other type of communication methods do not provide sufficient security and remote connectivity, such as for power line control applications.

Basic devices for connecting to the power line for communication and power supply have been designed and are used to provide service within LANs. But, due to the availability of more efficient competing technologies, the infrastructure for power line communication (PLC) has never been developed enough to make it a mainstream technology. This can be attributed to various reasons, including the higher cost of available devices, the lack of suitable devices for communication using the PLC technology, etc. The result has been that PLC has not found a path for growth in the standard voic and data communication field catered t by technologies such as xDSL, cell phones, and satellite communications. SUMMARY OF THE INVENTION

A smart-grid residential service (SRS) uses connected sensors for integrated service monitoring and control of home appliances via the Internet and an tn- home PLC network. Such sensors collect power usage information and include an intelligent master device and any of a communication enabled switch, a ZigBee® enabled switch, and a power control switch, each of which operate over a power line communication (PLC) network. The maste collects, compiles, and communicates collected data to the network. The SRS provides infrastructure, i.e. communication, IP-TV, climatic control, etc. monitoring and control, power monitoring and control of connection enabled home appliances, other utility usage monitoring, and security monitoring and control. Th SRS also provide billing and collection information for the monitored utilities to utility companies. Figure 5 is a block schematic diagram showing the SRS system 500 according to the invention. The home 510 is enabled with a power line communication (PLC) network having sensor units that provides a connection to enabl power monitoring and control capability with various appliances. The sensors used typically are a master (MST) 400 devic shown in Figure 4 and one or more selected from the group of: power control switch (SW) 100 devices shown in Figure 1 , ZigBee® enabled switch (Z-SW) 300 devices shown in Figure 3, and communication {Ethernet) enabled switch (ETH) 200 devices shown in Figure 2, all connecting to the ϊη-home PLC network 800 shown in Figure 8. A brief details of the sensor units used and their operation is provided below. The power control switch device (SW)

The SW 100 allows an appliance in the home or ofice to be connected to the power supply through a power plug on the device. The device provides for the monitoring of power consumption with capability for remote control of the power supply to th connected appliance via the Internet and the PLC network. Figure 1 is a block schematic diagram showing the SW 100. The SW 100 has power plug that is connected to the AC power distribution fines 101 through a power meter and relay 104. The relay in the power meter and relay module 104 provides the capability to switch on or switch off the supply to the power plug 103 remotely. It also allows for controlling the power supplied to the plug, where a power contra! module is included in the power meter and relay module 104, The power meter in the power meter and relay module 104 monitors the power usage by the appliances connected to the power plug. The power meter and relay module 104 is connected via bi-directional communication links 106 to a microcontroller (MCU) 107 similar to an Intel® 8051 The microcontroller accepts the information o the power usage and compiles ft prior to transfer to the broadband communication module 109. The power meter in the power meter and relay module 104 continuously monitor the flow of power to the power plug 103 and feed the information to the MCU 107 through the communication links .106. The power usage information is compiled by the MCU 107 and sent to a broadband communication module 109 via communication links 1 8 connected to a UART enabled port on the communication module 109 for onward transmission over the PLC network.

The data communication {Ethernet) enabled switch device (ETH)

The ETH 200 allows an appliance in the home or office to be connected to the power supply through the ETH 200 and provides for the monitoring of power consumption with capability for remote control of the connected appliance. The ETH 200 also provides the capability for broadband PLC-based data communication, where the data and communication devices are connected to the power distribution line through a communication port, typically an Ethernet port on the ETH 200, Multiple ETH 200 units can be used to establish a PLC based local area network (LAN) for communication. Figure 2 is a block schematic diagram showing the ETH 200. The ETH 200 is a combination of two sub-units: a broadband PLC sub-unit, and a SW sub-unit similar to SW 100. The SW sub-unit in this instantiation (ETH 200} uses broadband communication for information transfer on power usage and remote control of connected appliances over an Internet connection. The broadband PLC Ethernet bridg adaptor modul includes a 200Mbps communication sub- unit for broadband sharing including, for example, on line gaming, voice over Internet protocol (VOIP), Internet protocol television (IPTV), and for audio and video streaming.

In Figure 2, the communication subunif comprises an RJ45 connector 215 for establishing a connection to the subunit through a built-in PHY on an MCU 207. The power monitoring and control information of the associated power plug 103 is collected by the powe meter and relay unit 104 and sent to the MCU 207. The information is cached and processed by the MCU 207 and then passed to the broadband communication module 209 through a media independent Interface (Mil) port on the communication module 209. Th communication module 209, in this case, is common for communication and for power usage and status information transfer and control. Here, the communication module 209 is used to convert the incoming data stream into the broadband format used for PLC. The switch sub-unit of the ETH 200 operates similar t the SW 100. The power usage and power plug status information collected by the powe meter and rela module 104 ar also passed through the MCU 207 to the broadband communication module 209 for conversion to an output information stream using the broadband PLC format. Both the data stream and th power usage and status informatio stream are then transferred from the communication module 209 to the power distributio lines 101 in the home or office through the coupler filter module 111. Similarly, the communication module 209 receives the incoming communication data streams and the command and control instructions that are sent to the ETH 200 and passes them to th respectiv modules of the ETH 200 for processing. The broadband communication module 209 is also enabled with a uniqu address so that communication to it and from it can be identified. Because the broadband communication elements are bidirectional, the broadband communication module can send and receive full duplex broadband communication between Itself and any communication device connected to the RJ45 connector 21 S via the MCU 207. Similarly, the communication module 209 can send out information streams comprising the power usage and status of the plug to th AC power distribution lines 101, and receive command and control information streams from the AC power distribution lines 101. The received data and command and control informatio streams are decoded, the address is checked to see if it correct, and the streams are decrypted, if needed, based on the address. The communication module 209 then converts the received data stream into an analog format and sends it through the Mil interface of the MCU for transfer through the PHY to the J45 module 215, and thence to th connected customer device. Similarly, th communication module sends the command and control information to the WGU 207 for interpretation. The MCU 207 then generates instructions to the powe meter and relay module 104 that are used by the power meter and rela module 104 to control the power flow to the power plug 103, and thence to the appliance connected to the power plug 103,

The use of multiple ETH 200 devices within a home or office enables PLC local area network connectivity within the home or office, Here, the disclosed use of broadband communication within the PLC LAN, using the ETH devices, enables streaming media delivery capability and IPTV delivery capability for connected display devices, connected to appropriate communication units within the PLC LAN.

The ZigBee® enabled switch device (Z-SW)

Figure 3 is a block schematic diagram showing the Z-SW 300 device having an integrated ZigBee® unit 310. This allows a appliance In the home or office to be connected to the power supply and power line communication link through the Z- SW 30 which incorporates the ZigBee® device 310. The Z-SW 300 provides for the monitoring of power consumption with capability for remote control of the power flow to the connected appliance via the internet. The ZigBee® unit 310 provides for additional operational control and monitoring through the wireless connection to ZigBee® technology enabled appliances. The Z-SW 300 has a power plug 103 that is connected to the AC power distribution lines 101 through a power meter and relay 104. The relay in the power meter and relay module 04 provides the capability to switch on or switch off the supply to the power plug 103 remotely, it also allows for controlling the power supplied to the plug when a power control module is included in the power meter and relay module 104. The power meter in the power meter and relay module 104 monitors the power usage by the appliances connected to the power plug. The power meter and relay module 04 is connected via bi-directional communication links 106 to a microcontroller (MCU) 107. The MCU 107 accepts the information on the power usage from the power meter and re!ay module 104 and compiles this Information prior to transfer to the broadband communication module 109. The power mete in the power meter and relay module 1 continuously monitors the fiow of power to the power plug 1 3 and feeds the Information t the MCU 107 through the communication links 106. The power usage information is compiled by the MCU 107 and sent to a broadband communication module 109 via communication links 108 connected to a UART enabled port on the communication modul 109, thus enabling the compiled data to be transmitted out.

The operational commands for the ZigBee® unit 310 of the Z-SW 300 are received over the power line at the broadband communication module 109 as a data stream. These commands are demodulated, decrypted, and provided to the MCU 107 over the communication links 109 via the UART enabled port. The MCU 107 converts the data int instructions and passes them on to the ZigBee® unit 310 via the bidirectional port 311 over the Sink 312. The ZigBee® unit 310 sends out commands to the ZigBee® technology enabled appliance connected to the Z-SW 300, based o received instructions, to execute operational commands of reading meters, changing temperature settings, etc. The response after the command has been executed is sent back to the built-in ZigBee® unit 310 by the ZigSee® technology enabled appliance, which then transfers it to information and passes it on to the CU 107 via the bidirectional link 312 through the port 311. The MCU collects the information and forwards it with the address to be responded to by the broadband communication module 109 via communication Sinks 108 connected to the UART enabled port on the communication module 109.

In the example of Figure 3, the communication module 109 modulates the received information to a communication data stream for transmission over a broadband communication frequency band that is typically used for power line communication (PLC) over the AC power distribution lines within a local area network (LAN). The typical broadband used fo PLC communication band in the 2 to 30 MHz range, providing up to a 200 Mbps data rate. The communication modul 100 sends out the modulated the d&i stream over the broadband connection 110 to a coupler filter 111 which is connected to the AC power distribution lines 101 by power line connections 112. The coupler filter acts as a bi-directional high pass filter to filter out power line frequenc interference from the communication module. The broadband communication module 109 also demodulates the communication stream received over th AC power distribution lines 1 1 to provide the command and control instructions for power control and operational control to the MCU 107. The MCU 107 interprets any received command and control instructions to the power meter and instructs the power meter and relay module 104 for controlling the power flow to the power plug 103, The fvtCU 1 7 also interprets any operational command and instructions for the ZigBee unit 310 and passes on these to the ZigBee® unit 310 to be directed torn th ZigBee® technology enabled connected appliances.

The Master device (ftftST)

Th IVSST 400 provides the computing power and storage capability necessary to collect and compil power consumption information provided to it. The MST enables the collected data to be transmitted to a wid area network for group compilation. Th connected SW 100, ETH 200, and Z-SW 300 devices within the home or office monitor the power usage of devices and appliances connected to their respective power plugs. This information is sent over the local power distribution lines in the home or offic to the MST 400 for compilation of data on usage. With the capability and computing power available and with appropriate software, the MIST 400 can exert local and emergenc control of the appliances connected to the SW 100, ETH 200, and 2-SW 300 devices. The MST 400 also acts as a gateway connecting to the broadband communication modem to enable a communication pathway to the internet cloud wide area network (WAN) cloud.

Figure 4 is a block schematic diagram showing an MST 400. In this implementation, a 32 bit MCU is implemented as a system on chip (SGC) 407. The SOC 407 implementation provides for higher processing power and integration of modules with the MCU. The SOC 407 integrates a PHY into the MCU, allowing the R 45 connector 415 to connect the customer's modem device directly to a port on the SOC 407. This connection is a 1 /100 base TX, auto- negotiation Ethernet port and provides the gateway to the Internet through any connected modem for the PLC communication from all the connected ETH units within th PLC network. Th typical communication module of the MST 400 uses, for example, any one chosen modulation scheme from the list of modulation protocols comprising OFDM, QAM 1 24/256/64/16, DQPSK, DBPSK, and ROBO, for sending and receiving communication data streams to the connected ETH units within the PLC network. The frequency band used for broadband PLC is 2 to 30 MHz, with a data transfer rate of up to 200Mbps.

The gateway provided by the MST 400 is also used to send out the collected and processed information on the power usage and utility usage, as well as the status of the power monitoring and relay units within the PLC, for enabling control of the power plug 1 3. Any remote control commands are received from the Web via the gateway provided by th MST 400 for transfer to connected SW 100, ETH 200, and Z-SW 300 units for control of the power flow to connected appliances. In the MST 400, the modulation, frequency band, and data rates are the same as those used for the information and command transfer within the PLC network. The SOC 407 is enabled to enforce all communication related security protocols associated within the PLC network.

Ail data and powe monitoring and control information is sent to the SOC 407 by the connected SW 100, Z-SW 300, and ETH 200 within the home or office via the power distribution lines 101 through the coupler filter module 111 and the communication module 409. The communication module 409 of the MST 400 is used to demodulate the incoming streams and decrypt them prior to transferring them to the MCU that forms part of the SOC 407. Th SOC 407 receives the information and processes it, by compiling and consolidating it, for outward transmission to the Web,

The SOC 407 also ha a memory 417 associated with it, typically connected to a memory port on the SOC 407, The memory 417 enables the SOC 407 to store the received power monitoring and control information prior to processing and compiling the information. The memory 417 is also used to store the compiled information to transmit it out through th gateway optimally when th bandwidth usage for data communication is low. The memory 417 also stores the transaction history with a timestamp for the data communication and power usag information transmitted out, and for incoming remote commands sent to the connected SW 10 and ETH 400 within the home or office. The memory 417 provides for tracking of performanc and remote debugging capability with pinging and path tracking capability for the MST 400, as well as the connected SW 100 and ETH 200.

The MST 400 provides a power plug 103 of its own that is connected to the power distribution lines 101 throug a power meter and relay 104 for connecting any needed appliance with the necessary power monitoring and control capability. This monitored information is sent to the MCU, which is implemented as an SOC 407, to be combined with the information received over the PLC LAN over the power distribution lines 101 through the coupler filter module 111 and the communication module 409. This collected Information forms part of the power monitoring informatio input to the MST 400. The power monitoring information is stored i the memory and complied and processed for transmission to the monitoring sources in the WAN through the modem connected to the SOC 407 port with the RJ45 connector 415. The transfer of the compiled information is typically done as in store and forward manner with storage in the memory 417 to enable best use of the available bandwidth of the gateway, as discussed earlier.

Remote control commands received via the gateway are received through duplex port with the RJ45 connector 415 from the connected modem. These control commands are interpreted by the SOC 407 of th MST 400 and sent to the respective SW 100, ETH 200, or Z-SW 300 to which it is addressed over the broadband PLC network through communication modul 409 and coupler filter module 111 for necessary action at the addressed receiving units.

Usage of the sensors over tie PLC network

As described above, the individual sensor devices S 100, ETH 200, Z-SW 300, and MST 400 are used in th appropriate locations to connect and control appliances on the PLC network. The SW devices 100 are used to monitor and control the powe that is supplied to connected appliances. The Z-SW 300 devices enable the power monitoring and control of the connected appliances, as with the SW 100 and, in addition, provide remote operational control of a connected ZtgBee® technology enabled intelligent appliances. Also, the Z-SW 300 on the PLC network 600 uses ZtgBee® technology to connect to intelligent utility meters for gas, water, etc, for monitoring of the utility usage. The ETH 200 is used to provide power monitoring and control capability, as well as communication and streaming media capability for connected communication and TV units within the home. The MST 400 is used to collect the power usage information from he various sensor units connected over the PLC circuit and to store and consolidate the usage information. Th ST 400 acts as a gateway to the internet wide area network (WAN) to send and receive data and control information. The received data and communication packets are forwarded to the ETH 200 devices to enable communication and streaming media capabilities of the PLC network.

The detailed operation of the sensor units and the in-home PLC network ar described in the patent application serial no. 13/197,623, filed August 3, 2011 which, in turn, claims priority to U.S patent application serial no. 13/153,194, filed June 3, 2011 which, in turn, claims priority to U.S. patent application serial no, 13/032,454, filed February 22, 20 1, each of which claim inventions made by the same inventors and assigned to the same assignee, and each of which are all incorporated herein in its entirety by this reference thereto,

As shown in Figure 6, the in-home PLC network 600 comprises the various home appliances and meters connected through the sensor devices. The oven 601 and Itghts 602 are connected to the power line of the in-home PLC network through the SW 100-1 and SW 100-2 that provide monitoring and control of power supply to these appliances. The ETH 200 are used to connect to any communication and streaming media appliances to the PLC network, such that the communication appliances use the PLC network's communication capability to send and receive voice, data, and streaming video. As shown in the exemplary PLC network 600, the ETH 200-1 connects the communication unit 603 to th PLC network 600, The ETH 200-2 is used for connecting the computer 604. Similarly, the IP-TV 606 and th security monitoring units In th home 606 ar connected to the PLC network 600 using ETH device 200-3 and 200-4, respectively. The Z-S units 300 are used to connect the ZigBee® enabled intelligent appliances to monitor and control the power usage and also us the ZigBee® connection to control the operation of the intelligent appliances. The Z-SW 300-1 Is used to connect th ZigBee® enabled refrigerator 607 and the Z-SW 300-2 is used to control the operation of the ZigBee® enabled home climate control 608» Th Z-SW 300-3 and 300-4 are both connected to ZigBee® enabled water-meter 609 and ZigSee® enabled gas-meter ©10 to facilitate monitoring and reading of the water usage and gas usage of the home, The SRS system in Figure 5, the MSJ 400-1 collects all the usage information from the home 510 and consolidates this information into a usable format for storage on the MBJ 400-1. The MST 400-1 then sends the consolidated information to an SRS server 520, shown as the SRS system of Figure 5, over the WAN 530. The SRS server 520 provides administrative communication and control to the home appliances over the WAN 530 through the MST 400-1 and th PLC network 800 using the built-in administrative communication and control capability 521 Figure 7 is a block schematic diagram that shows the administrative capabilities 521 established on the SRS server 520, In this embodiment, all of the administrative capabilit is provided through a personalized graphical user interface (GUI) 710 that provides the customer access to the data for checking and providing needed operational instructions. The various administrative items 720 that can be addressed or reviewed by the customer using the GUI 710 include, for example, current metered utilit usage with individual appliance usage, prior billing and payment Information, utility usage trend over time periods, security assurance status, monitoring and control engagement details, monitoring and management of appliances through the system connections, and additional customer suppor activities and management support activities.

Th SRS system 500 also provides the consumer with the capability to monitor and compare current utility usage with past usage data for utilities to optimize and reduc the usage at individual connected appliances. It also provides the consumer with the capability to monitor and control, via remote as well as local control, the individual connected appliances through the WAN and PLC network to reduce usage and eliminate waste. Thus, - a significant aspect of the invention is its contribution to 'green' technology.

Figure 8 is a block schematic diagram that s orn a group of service software 522 running on the SRS server 520. The software groups 810 allow the system to provide the necessary services to the consumer. The software covers the management functions described previously and also provides security for financial transactions and personal information stored by providing for firewalls, password protection, etc, for the information received and stored in the SRS server 520. In addition, the software provides for encryption, validation, and other communication authentication for any inputs to or outputs from the SRS server 520.

Figure 9 is a block schematic diagram that shows a sample of the information stored in the databas 523 of the SRS server 520. This information includes, but is not limited to, subscriber information 910, including validation and security information; configuration data fo the home 920, which includes information on the home , home alarm setting, and other configuration information, ate,; financial, billing, and payment related information 930, that includes information regarding the billing and payment process information of the customer and th payee; power and utility usage of the home 940 that is provided as a consolidated statement by the ST 400-1, where the information is retained in a format that allows tracing the usage back to individual connected appliances in the home, thus allowing the consumer full capability to monitor and control the usage; and miscellaneous information that supports the custome 950.

Even though the use of the SRS server is shown herein as being connected to one home 510, those skilled in the art will appreciate that the invention is not so limited. The SRS server 520 typically has enough computing power and storage capability to handle a number of connected homes in a local area that form a home group. Once the information is collected and stored, the SRS server 520 provides the utility usag information to appropriate connected utility center offices §40 of utility companies to check and generate billing for individual homes, such as home 510 in the home group, Typical connected utility companies can include a powe and gas utility 541, water supply utility 542, security company 543, TV company 544, and phone and Internet company 545. The bii!s are sent back to the SRS server 520 by the individual utilities .540, where it can be checked by the consumer against the utilit usage using the PLC network 600 and WAN 530 connectivit to th SRS server 520, Onc agreement has bee reached, the consumer initiates payment to the utility company through the capabilities of the SRS server 520 of the SRS system 500.

Figure 10 is a flowchart 1000 of th SRS system 500 showing the operation of billing and payment process for utilities.

Each connected sensor devic in the home collects the power usag information and the utility usage information from the connected appliances and meters. For example, the Z-SW 300-3 monitors th water usage using the ZigBee® connection to the ZigBee® enabled water meter 609 (S1O01).

The connected sensor devices comprising at least any on of an SW 100, ETH 200, Z~SW 300 send the collected informatio to the in-home MST 400-1 over the power line of the in-home PLC network 600 for consolidation. In this example, the water usage information from the meter 803 sent by the Z-SW 300- 3 is also included with the information sent over the PLC network 60 {S1O02}.

The ST 400-1 receives the information sent over the PLC network 600 by the individual sensors and stores and consolidate the information wher needed, for example the power usage for the home is consolidated {$1003}. The MST 400-1 transmits the individual and consolidated information to the connected SRS server 520 over the internet when requested by the SRS server 520 (81004). The SRS server 520 receive the information from all the homes associated with the SRS server 520. The received information from each home is finked with the home identity and consumer identity and stored in pre-defined format in the database 523 of the SRS server 520 with full traceability to the originating in- home sensor devices. It also consolidates the utility usage information for individual utiiity center, such as PG&E 541 , water utility 542, home securit service 543, TV utility 544, communication utilit 545, etc, separately and stores the information in the database 523 (S1005).

The consolidated usage information of each utility, for each home, for specified hilling periods, as generated by the SRS server 520 is sent to the specific utilit center. For example, the consolidated information from home 510 on water usage over a specified billing period is sent to the water utility center 542 for generating a bill for the period, In the same way, the consolidated usage information for power usage and gas usage from home 510 is sent to PG&E for generating a bill for power and gas for the specified period (SI 006).

The utility centers 541 to 545 accept the billing information from the home 510 sent to them by the SRS server 520 over the WAN. The bill for the home 510 for a specific utilit usage for the period is generated by th individual utiiity center and sent back to the SRS server 520 for forwarding to the consumer over the communication pathway over the WAN to the MST 400-1 of the home 510 (S1007).

The SRS server receives the bills for the hom 510 from the utility center 541 to 545, stores a copy of each for reference in the data base 523, and sends th bis to the MST 400-1 of home 510 fo checking and payment (S1008 , The MBT 400-1 receives the bill for the individual utilities and provides it to the consumer over the communication channels of the PLC network 600 for viewing and action (S1-00 ). The consumer using the communication capability of the ETH 200, e.g. the ETH 200-2 using the Internet connection, checks the bills received against consolidated utility usage information stored in the memory of the ST 400-1 and also checks the prior usage for similar periods of usag stored in the data base 523 of the SRS server 520 (S1 10).

Once th checking and verification is done, the consumer pays the individual bills to each of the utilities using the secure bill payment facility, using any approved means of payment available through the SRS system 500. The SRS system is then able to store all the payments made for future verification in the database 523 of the SRS server 520 for future tracking. The approved mode of payment can include any of credit card payment, bank transfer, etc. ( 1011).
