BACKGROUND OF THE INVENTION TECHNICAL FIELD
The invention relates to interfacing ZigBee® technology with power line networking that is enabled for communication and media streaming for remote monitoring and control of utilities such as power, gas, and water. More particularly, the invention relates to a sensor having an integrated Zigbee® device for communication with Zigbee® enabled appliances to control and monitor Zigbee® enabled appliances.
DESCRIPTION OF THE BACKGROUND ART
Communications via power lines has been known from early in the 20th century. Due to its higher costs and other limitations for extending connectivity, the use of power line communication (PLC) systems has been limited to local area networks (LANs) within homes or offices or, at best, within apartment complexes. PLC has also found a limited number of applications where other types of communication methods do not provide the 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 used to provide service within LANs. Due to more efficient competing technologies, the infrastructure for PLC never developed to make it a mainstream technology. As a result, more advanced devices for communication using the PLC technology also were never developed. It is advantageous to identify applications where PLC technology can be optimally used and to develop devices and systems to cater to such applications. One such application that is emerging is in connection with the collection of information and the provision of remote control capability for appliances to reduce the carbon footprint of the home. If this emerging application can simultaneously provide a local area network capability that caters to the needs of communication and streaming media delivery within a home or office, it would be an optimum application for PLC technology. While this is a promising application for the future growth and development of PLC technology, it is still necessary to develop and implement suitable sensor units and systems to meet the needs of this technology and to bring forth its full potential.

DETAILED DESCRIPTION OF THE INVENTION
ZigBee® smart energy (www.zigbee.org/) is the world's leading standard for interoperable products that monitor, control, inform, and automate the delivery, control, and use of energy and water. It helps create greener homes by giving consumers the information and automation capability needed to reduce their consumption easily and save money. These products also make it easy for utilities and governments to deploy smart grid solutions that are secure, easy to install, and consumer-friendly. A presently preferred embodiment of the invention combines the residential power monitoring and control capability established using a PLC network with an integrated ZigBee® device to provide a powerful tool for integrated power and operational control of connected appliances in the home or office.
An embodiment of the invention provides a method and apparatus for monitoring and control of power usage, as well as operational control of connected devices. A sensor device integrates ZigBee® technology into the power switch device. The sensor device allows collection and control of the power usage, monitors utilities usage, and controls operation of connected in-home appliances enabled with ZigBee® technology.
In an embodiment, the sensor device uses the PLC network in the home to transfer collected data and to provide remote control capability to connected appliances. The sensor device, in conjunction with a master switch device, a communication enabled switching device, and the power switch device, provides an integrated home environment for communication, streaming media, monitoring, and remote control of power usage, as well as remote operational monitoring and control of connected appliances in the home.
A new sensor device, which integrates ZigBee® technology into the power switch (SW) device is disclosed. The herein disclosed integrated ZigBee® technology enabled power switch (Z-SW) device allows collection and control of the power usage by, and operational control of, connected in-home appliances that have been enabled with ZigBee® technology. The Z-SW device uses the PLC network in the home or office to transfer collected data and to provide remote control capability for power switching, as well as for operation of an appliance connected to the Z-SW device. A Z-SW device, working in conjunction with a master switch (MST) device, a communication enabled switching (ETH) device, and the power switch (SW) device, enables an integrated home environment for communication, streaming media, monitoring, and remote control of power usage, as well as remote operational monitoring with control of the connected appliance in the home or office. Those skilled in the art will appreciate that, while the home and office are discussed herein with regard to application of the herein disclosed invention, other environments may be serviced by the invention as well , and the invention is not limited to only home and office applications.
The development of green technologies and the need for monitoring and control of the carbon footprint of homes and offices has created a need to assess power usage patterns and the magnitude of usage remotely, and to supervise and control the power used by individual appliances remotely. It is advantageous for the consumer to monitor and control power use on a micro level. Providing the proper tools, such as the SW and Z-SW, allows the consumer to exercise the necessary constraints and controls on power use. It is also necessary to monitor the usage pattern and collect data on a macro level to develop policies that are beneficial to the overall reduction of the carbon foot print at the home and office level, as well as on a national level. Empowering the individual and the society to exercise the necessary controls by monitoring and controlling the power usage is an area where the PLC and control can be effectively and optimally used.
An embodiment of the invention, by combining ZigBee® technology into the power switch (SW) device enables the operation of ZigBee® technology enabled intelligent appliances connected to the Z-SW to be controlled via a wireless connection established by the built in ZigBee® device. Further, ZigBee® technology integration into a Z-SW enables monitoring of water, gas, air- conditioning, and security systems within the home or office through the in-built communication channel of the Z-SW. The operational control and monitoring information collected by the built-in ZigBee® functionality is combined with the power usage, monitoring, and control enabled by the SW for connected appliances. This information is transmitted over the in-home PLC network efficiently for any compilation or action required. This above capability is established in addition to the PLC LAN capability made available by use of the communication enabled power monitoring and control device (ETH) and the master unit (MST) described previously in the patent application serial no. 13/032,454, which application is incorporated herein in its entirety by this reference thereto. Figure 1 is a block schematic diagram of the SW unit 100 without the integrated ZigBee® device. This arrangement allows an appliance in the home or office to be connected to a power supply through the SW device. The SW device provides for the monitoring of power consumption, with the capability for remote control of the power flow to the connected appliance via the Internet. The SW unit 100 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 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 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 104 is connected via bi-directional communication links 106 to a microcontroller (MCU) 107, for example a microcontroller similar to an Intel® 8051. The microcontroller accepts the information on power usage and compiles it prior to transfer to the broadband communication module 109. The power meter in the power meter and relay module 104 continuously monitors the flow of power to the power plug 103 and feeds 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 108 connected to a UART enabled port on the communication module 109. In Figure 1 , 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 PLC over the AC power distribution lines within a local area network (LAN). The typical broadband used for PLC communication band in the 2 to 30 MHz range provides an up to 200 Mbps data rate. The communication module 109 sends out the modulated data stream over 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 frequency from the communication module. The broadband communication module 109 also demodulates the communication stream received over the AC power distribution lines 101 to provide command and control instructions for power control to the MCU 107. The MCU 107 interprets any received command and control instructions and instructs the power meter and relay module 104, thus controlling the power flow to the power plug 103.
Figure 2 is a flowchart 2000 showing the operation of the SW 100 as it collects and transmits power usage and power plug 103 status information when an appliance is connected to the power plug 103.
An appliance, such as but not limited to, a refrigerator, a washer, or an oven, is connected to the power plug 103 (S2001).
The power plug 103 is enabled when the relay in the power meter and relay module 104 is closed (relay enabled). Power flows from the AC power distribution lines 101 supplying the home or office to the appliance through the power meter and relay module 104 and the noise filter 103a (S2002).
The power meter and relay module 104 monitors the power usage of the appliance by checking the power flow through the power meter and relay module 104 and the plug 103 (S2003). The power usage information and the on state or off state of the relay and, hence, power connection are collected by the power meter in the power meter and relay unit 104 (S2004).
This collected information on the status of the power connection is passed on to an MCU 107 for compilation and consolidation (S2005). The MCU 107 caches the received information. The MCU 107 compiles and consolidates the cached information making it ready for transfer to an MST (S2006). The prepared information, ready for transfer to a master unit (MST) connected on the power distribution lines 101 , is forwarded with the address of the MST to a communication module 109 (S2007).
The communication module 109 receives the information and address of an addressee from the MCU 107. The MCU 107 encrypts the information and combines the encrypted information with the address provided (S2008).
This encrypted information and address are then modulated by the communication module 109. The broadband modulation frequency band used and the type of modulation are as defined in the description of the SW (S2009).
The communication module 109 then sends this modulated information stream onto the AC power distribution lines 101 for transmission to the MST through a coupler filter 111. The filter blocks unwanted frequencies from entering and impacting the operation of the communication module 109 (S2010).
Figure 3 is a flowchart 3000 showing the operation of a SW 100 unit while providing for remote control of the power flow to an appliance that is connected to the power plug 103. Any information or status changes due to a remote command and control stream are sent back over AC power distribution lines 101 as described in Figure 3.
The command and control input stream modulated by the correct transmission frequency to control the status and power flow through the SW 100 remotely is delivered over the AC power distribution lines 101 (S3001). The command and control input stream is passed to the communication module 109 of connected SW 100 through the coupler filter module 111. The communication module 109 demodulates the received command control input stream (S3002).
The addressee of the received demodulated input stream is checked and, if found to be of the specific SW 100, the demodulated input stream is accepted by the SW100 for further processing by the communication module 109 (S3003). The demodulated command and control stream is decrypted in the communication module 109 to extract the associated command and control inputs for the SW 100 (S3004).
The extracted command and control inputs are passed to the MCU 107 for caching and interpretation (S3005).
The MCU 107 caches the inputs received and interprets them to generate a set of instructions for execution by the power meter and relay module 104. The interpreted instructions include instructions to enable the power flow to the power plug by engaging the relay and to disable the power flow to the power plug by disengaging the relay. If the power meter and relay 104 include power control circuitry, then specific control instructions are provided to the connected appliance on power input (S3006). The generated instructions are sent to the power meter and relay module 104 of the SW (S3007).
The power meter and relay module 104 receives the instructions sent by the MCU 107 for power flow control to the connected appliance (S3008).
The power meter and relay module 104 acknowledges the instructions from the MCU 107 and executes the instructions received to enable, disable, or otherwise control the power flow to the appliance connected to the power plug 103 (S3009).
The status of the relay and the power usage of the connected power plug 103 are updated on the power meter and relay module 104, and updated power usage and relay status is sent to the MCU 107 for communication back to the initiating remote site (S3010).
Figure 4 is a block schematic diagram of the Z-SW 400 unit with an integrated ZigBee® device 410. This arrangement allows an appliance in the home or office to be connected to the power supply and PLC link through the Z-SW 400 unit which incorporate a ZigBee® device 410. The Z-SW 400 device monitors power consumption and provides a capability for remote control via the Internet of the power flow to the connected appliance. The ZigBee® device 410 also provides operational control and monitoring through the wireless connection to ZigBee® technology enabled appliances.
The Z-SW unit 400 has a power plug 103 that is connected to the AC power distribution lines 101 through a power meter and relay module 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 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 used by the appliances connected to the power plug. The power meter and relay module 104 is connected via bidirectional communication links 106 to a microcontroller (MCU) 107, which can be a microcontroller that is similar to an Intel® 8051. The MCU 107 accepts the information on the power usage from the power meter and relay module 104 and compiles it prior to transfer to the broadband communication module 109. The power meter in the power meter and relay module 104 continuously monitors the flow of power to the power plug 103 and feeds 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 108 that are connected to a UART enabled port on the communication module 109, thus enabling the compiled data to be transmitted out.
The operational commands for the ZigBee® device 410 of the Z-SW 400 are received over the power line and received by the broadband communication module 109 as a data stream. The data stream is demodulated, decrypted, and the resulting data are provided to the MCU 107 over the communication links 109 via the UART enabled port. The MCU 107 converts the data into instructions and passes them on to the ZigBee® device 410 via the bidirectional port 411 over the link 412. Based on received instructions, the ZigBee® device 410 sends out commands to a ZigBee® technology enabled appliance that is connected to the Z-SW 400. The Zigbee® device executes operational commands, for example reading meters, changing temperature settings, etc. The response after the command has been executed is sent back to the ZigBee® device 410 by the ZigBee® technology enabled appliance. The Zigbee® device then converts the response to an information format and passes it on to the MCU 107 via the bidirectional link 412 through the port 411. The MCU collects the information and forwards it, with the address to be responded to, to the broadband communication module 109 via communication links 108 connected to the UART enabled port on the communication module 109.
In Figure 4, 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 PLC over the AC power distribution lines within a LAN. The typical broadband used for PLC communication band in the 2 to 30 MHz range provides an up to 200 Mbps data rate. The communication module 109 sends out the modulated the data stream over 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 is a bi-directional high pass filter that filters out power line frequency from the communication module. The broadband communication module 109 also demodulates the communication stream received over the AC power distribution lines 101 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 to control the power flow to the power plug 103 accordingly. The MCU 107 also interprets any operational command and instructions for the ZigBee® device 410 and passes these to the ZigBee® device 410 to be directed to the ZigBee® technology enabled connected appliances.
Figure 5 is a block schematic diagram that shows typical applications where a ZigBee® technology can provide operational status and control capability within a home or office environment. These applications can include, for example, the monitoring of gas, water, and power usage by providing remote read capability for the utilities, monitoring of security apparatus within the premises, temperature monitoring and control capability, monitoring and control of light fixtures, and monitoring of ZigBee® technology enabled smart appliances within the home.
Figure 6 is a flow diagram 6000 showing the incoming operational status handling for the ZigBee® device 410 of the Z-SW 400. This operation of the Z- SW 400 is in addition to the power monitoring and control operation of the standard SW unit 100 shown in Figure 1.
The ZigBee® technology enabled appliance is connected to the power by plugging it into the power plug 103 of the Z-SW 400 unit (S6001).
The built in ZigBee® device 410 on the Z-SW 400 turns on, monitors, and controls the power flow into the ZigBee® technology enabled appliance (S6002). The ZigBee® device 410 on the Z-SW 400 is linked to the ZigBee® technology enabled connected appliance to establish communication and connection between the Z-SW and the ZigBee® technology enabled appliance (S6003). Operational information and status of the ZigBee® technology enabled appliance is collected and communicated to the Z-SW 400 through a communication link established between the ZigBee® device 410 on the Z-SW 400 and the ZigBee® technology enabled appliance ( S6004).
The received information is passed to the MCU 107 for processing by the ZigBee® device 410 via the communication link connected to the bi-directional port (S6005).
The MCU 107 caches the information received from the ZigBee® device 410 and converts it into the necessary format, including an address for onward transmission to the master unit over the power line (S6006). The MCU 107 then sends the prepared information with the forwarding addresses to the broadband communication module 109 of the Z-SW 400 over the link 108 connected to the UART on the communication module 109 (S6007).
The communication module 109 encrypts the received information for security where needed (S6008).
The encrypted data is modulated and sent via the coupler filter 111 to the power line network 101 for delivery to the MST for necessary action, including onward transmission to the addressee over the Internet where necessary (S6009).
Figure 7 is a flowchart showing the handling of the remote operational control instructions sent to a connected ZigBee® technology enabled appliance connected to a Z-SW 400 unit for power monitoring and control, as well as for operational control. Remote commands and a control stream is received from the MST unit over the AC power distribution lines 101 by the communication module 109 of the Z-SW 400 through the coupler filter module 111 (S7001). The communication module 109 checks the address to verify that the Z-SW 400 is the intended recipient of the data steam and accepts the command and control instruction stream (S7002).
The communication module 109 of the Z-SW 400 demodulates the received data stream to extract the command and control instructions (S7003).
The communication module 109 further decrypts the command and control instructions to extract the information (S7004). The extracted information is sent by the communication module 109 to the MCU 109 on the Z-SW 400 via the link connected between a bidirectional communication port on the MCU 109 and the UART on the communication module 111 (S7005). The MCU 109 receives the information stream and interprets the command and control instructions contained therein. It prepares the operational instructions for transmission to the integrated ZigBee® device 410. (S7006).
The operational instructions are sent to the integrated ZigBee® device 410 of the Z-SW 400 through the bi-directional port 411 and the communication link 412 (S7007).
The operational instructions are sent by the integrated ZigBee® device 410 addressed to the ZigBee® technology enabled connected appliance using pre- established wireless connection (S7008). The operational instructions sent are received by the addressee ZigBee® enabled device on the connected appliance and provide the necessary inputs to the appliance to change or modify the operational status of the connected appliance (S7009).
The resultant operation status is updated and transmitted back to the integrated ZigBee® device 410 on the Z-SW 400 for transmission back to the originator of the command and control instruction stream through the power line and Internet as necessary (S7010).
Typical connection for the units within the home or office
Figure 8 is a block schematic diagram 800 showing powered management and communication connectivity using the four types of units of an exemplary embodiment of the invention. The SW units are used where the requirement is for power connection capability with monitoring and control of power, but without the need to connect a communication device into the PLC LAN.
The Z-SW units allow for power monitoring and control, as well as operational control of the ZigBee®® technology enabled appliances. The Z-SW can also be used to connect directly to ZigBee® technology enabled metering devices for monitoring usage, such as gas use and water use.
The ETH devices provide the ability to have a communication device connections to the PLC LAN, while providing a power plug or power source which can be monitored and controlled.
Multiple SW, Z-SW, and ETH units can be used to establish the power monitoring and control for the home appliances and provide connectivity for data communication on the PLC LAN level. The use of a single MST provides the capability to establish a WAN gateway, thus enabling the PLC LAN to communicate with the outside world in view of various security and connection rules. The MST is also used as a collection and compilation point for power monitoring, where the power usage within the home with connected SW, Z-SW, and ETH units is received and compiled. Because there is connectivity with control capability on each SW, Z-SW, and ETH unit, the power delivery through each of these SW, Z-SW, and ETH units can be monitored and controlled from any of the communication devices connected to the PLC LAN. Further, this collected information on any of the power plugs can be accessed from the WAN using connected communication devices to monitor the status and provide remote control commands through the WAN gateway. This capability is controlled by the permissions, authorizations, and security rules established for connection into the PLC LAN through the MST. The MST also acts as a collection and compilation point for the operational status of the ZigBee® enabled appliances. This enables the user to have complete information concerning the impact of various operational decisions on the operation and working of the ZigBee® enabled appliances over specific periods for budgeting and control purposes.
Because communication connections to the outside world and within the PLC LAN are all broadband enabled, the system can provide steaming media capability within the PLC LAN. It can also access and enable streaming media delivery to display devices connected using ETH units through the WAN gateway.
To facilitate macro level collection and compilation of power usage information, the collected power monitoring and usage information is transmitted over the WAN gateway to one or more central power usage collection units. These units collect the data for analysis and to provide input to the public bodies for use in making policy decisions on greenhouse gas reduction requirements, etc. Although the invention is described herein with reference to the preferred embodiment, one skilled in the art will readily appreciate that other applications may be substituted for those set forth herein without departing from the spirit and scope of the present invention. Accordingly, the invention should only be limited by the Claims included below.
