A power control system/method implementing Internet based access to hybrid home automation networks is disclosed. The system utilizes a smart gateway power controller (SGPC) to selectively switch an AC power source to a load device under control of local or remote network commands that may be routed through a variety of network interfaces and protocols present within a home or other structure-local communications network. SGPC configurations may be nested within a home automation network to permit separation of control for load devices within a common home automation environment. Present invention methods may include routing protocols between disparate home automation networks as well as remote access protocols that permit control of disparate home automation networks via the Internet using a wide variety of remote access interfaces including mobile devices, tablet computers, laptops, desktop computers, and the like.
Internet based home automation devices. These devices can be accessed with Internet capable equipment, such as a smartphone or a laptop. Existing Internet based home automation devices, however, suffer the following drawbacks:. Consumers cannot easily access the devices both at home and away from home.
Consumers have to log on to a service provider's website while away from home, and from there read the data and control the automation device. Consumers cannot communicate with the device directly.
This presents some security issues as well as performance issues. This type of device is usually intrusive to existing home network as consumers either need to get a new home gateway to work with the automation device or add a new router or hub to the home network to “relay” the signals. Home Automation Networking. Most homes today have the last mile communication connection (e.g., a cable link, a fiber optic or a telephone line).
Inside a home there is a gateway device that terminates the last mile network and routes the signal between the consumer devices at home and the network outside home. The communication of the gateway with the home devices can be wireline or wireless. Wireline communication includes power line, cable, and Ethernet. But predominantly, the communication trend is wireless based on WiFi. The communication of the home gateway with home devices forms home network.
In this document, it will be assumed that the home gateway is a WiFi AP and that the home network is a WiFi home network. Service Provider Centric vs. Consumer Centric—The service providers have the control, with consumers permission, over when and what data to collect and when and what device to control. This is a service provider centric approach. There are privacy issues and the issues of consumer's ability to access the data. For example, when a consumer is at home, must he/she login to a service provider's site to look at data and exercise control or can he/she easily access the information and exercise control directly from/to the automation devices at the home, from a laptop or a smartphone. Deployed automation and energy management systems of today require the consumer to remotely login to a service provider site for information and provides no method for easy and direct access to or control over the device.
Network Issues—When an automation device is deployed at home, it either has to work with existing home residential gateway (the AP) or replace the existing home gateway with a new home gateway that knows how to communicate with the automation device. With ZIGBEE® as part of the many automation/energy management system, it is frequently the case that a new home gateway must be used in place of the existing one. This “intrusive” setup that often requires professional setup forces consumers to make changes in their home network setup. In addition, once the energy management network is deployed at a home, it is not easy to deploy additional energy management devices from other vendors.
Performance—As mentioned above, many existing home energy systems do not allow consumers to access or control them DIRECTLY via a smartphone or a tablet, even if the user is proximal to the energy system. Instead the consumer must either have to use a dedicated device like a remote control or have to go to a service provider's website to exercise control. It involves sending signals to the home gateway, to an Internet server, and back to the home gateway and back to the consumer's automation device. As a result, it introduces delays, sometimes significant delays, depending on the overall network traffic. The present invention in various embodiments addresses one or more of the above objectives in the following manner.
The present invention as generally depicted in FIG. 1 ( 0100) implements a Smart Gateway Power Controller (SGPC) ( 0110) that acts as a bridge between a power source ( 0101) and associated power source cabling ( 0102) and power load cabling ( 0103) to supply power to one or more electrical loads ( 0104). The SGPC ( 0110) incorporates a power switch ( 0111) and power/energy meter ( 0112) that are interfaced to a microcontroller unit (MCU) ( 0113) or other computing device operating under control of software read from a computer readable medium ( 0114). The MCU ( 0113) interfaces with one or more WiFi wireless network interface modules ( 0115, 0116) which communicate to one or more computer networks that may include the Internet, local computer networks, and/or other networks such as ZIGBEE®, etc. System Application Context ( 0200). A typical application context for the present invention is generally illustrated in FIG.
2 ( 0200), wherein a user ( 0201) interfaces with a graphical user interface (GUI) ( 0210) that may be embodied on any number of devices including but not limited to a mobile phone ( 0211), laptop/desktop computer ( 0212), and/or tablet computer ( 0213). This GUI typically operates under control of software read from a computer readable medium ( 0202) that incorporates network protocols that communicate over a computer network ( 0203) (such as the Internet) to a local wireless router ( 0204). This wireless router ( 0204) then communicates with one or more SGPC devices ( 0221, 0222, 0223) to control power switching to any number of load devices ( 0231, 0232, 0233, 0234) using any number of SGPC associated power receptacles.
Method Overview. The numerous innovative teachings of the present application will be described with particular reference to the presently preferred embodiment, wherein these innovative teachings are advantageously applied to the particular problems of a POWER CONTROL SYSTEM AND METHOD. However, it should be understood that this embodiment is only one example of the many advantageous uses of the innovative teachings herein. In general, statements made in the specification of the present application do not necessarily limit any of the various claimed inventions.
Moreover, some statements may apply to some inventive features but not to others. Automation Not Limitive. The present invention anticipates a wide variety of applications for the power control system/method taught herein. Within the application context, the term “portable computing device” and its variants should be given its broadest possible interpretation, to include but not bet limited to laptop computers, cellphones, tablet computers, and other like and typical applications where computing devices are configured in a portable or semi-portable manner. While the present invention anticipates that the computational capability of the “computing device” described herein may vary widely, it is anticipated that some aspects of the present invention may be implemented using software embodied in computer readable program code means embodied on a tangible medium that is computer readable. Invention Nomenclature.
The Smart Gateway Power Controller (SGPC) forms the basis of much of the functionality in the present invention and addresses the deficiencies associated with the prior art home automation systems. 1 ( 0100) generally illustrates the functional blocks of a typical SGPC, with one or more functional blocks being physically implemented as one component. It generally comprises a small form-factor device directly plugged into a power outlet. It contains one or more power sockets, into which consumers plug in power suppliers to their home appliances. One or more independent relay switches controlled by the MCU are connected to the socket(s).
The switch(s) can be turned on and off by the MCU. A typical SGPC can measure the energy consumption of the plugged in appliances in terms of instant power consumption (watt), energy consumption (watt-hour), voltage and current. A typical SGPC is a cost-effective 3-in-1 home automation device: network gateway+load control switch+energy measurement.
The small form factor of this device has the size of a regular power adaptor. On the networking side, it comprises two-way communication with the Internet and 2-way DIRECT communication with a WiFi devices (PC, laptop, smartphone) at home. A SGPC works with home residential gateway as a client (station), and use the residential gateway to communicate with the Internet cloud.
On the other side, it serves as a secondary or sub-gateway to a subnet that consists of a set of WiFi based client devices it has control over, as well as any consumer devices that can communicate with it. If the SGPC has the wireless interface to communicate with ZIGBEE® devices, it can also control and read data from the latter. 3 ( 0300) illustrates the two roles a SGPC plays. An exemplary system embodiment depicting the proxy server mode is generally illustrated in FIG.
Here the user ( 1701) interacts with a GUI ( 1710) running software read from a computer readable medium ( 1702) and communicates over a computer network ( 1703) to a proxy server ( 1731). The proxy server ( 1731) maintains an ID/IP translation database ( 1732) that translates a SGPC ID to an IP address/port value/subnet vector ( 1733). This database ( 1732) is populated by the SGPC ( 1721) operating a background IP/Port updating process ( 1722) that continuously checks for changes in the SGPC IP address and reports these changes via the computer network ( 1703) to the server ( 1731) for placement in the ID/IP database ( 1732). In this fashion any changes in the IP address or subnet routing that occur in the SGPC ( 1721) are reflected in the ID/IP database ( 1732) for use by the user GUI ( 1710) in communicating with the SGPC ( 1721). Exemplary Proxy Server (Pull) Mode Method Embodiment ( 1800). An exemplary system embodiment depicting the proxy server mode is generally illustrated in FIG.
Here the user ( 1901) interacts with a GUI ( 1910) running software read from a computer readable medium ( 1902) and communicates over a computer network ( 1903) to a SGPC ( 1921) to register the communications device ( 1911, 1912, 1913). This registration function typically involves providing a unique communications device ( 1911, 1912, 1913) identifier such as an e-mail address or telephone number (for text messaging). The SGPC ( 1921) notifies the communications device ( 1911, 1912, 1913) in the event of any change of its gateway IP address, port number, subnet vector, or other access information using the messaging techniques described above.
Software resident on the communications device ( 1911, 1912, 1913) uses this message information to determine the current IP address/port/subnet vector path for the next communication with the SGPC ( 1921). Within this context an ID/IP translation database ( 1932) that translates a SGPC ID to an IP address/port value/subnet vector ( 1933) may be maintained. This database ( 1932) is populated by the SGPC ( 1921) operating a background IP/Port updating process ( 1922) that continuously checks for changes in the SGPC IP address and reports these changes via the computer network ( 1903) to the server ( 1931) for placement in the ID/IP database ( 1932). In this fashion any changes in the IP address or subnet path routing that occur in the SGPC ( 1921) are reflected in the ID/IP database ( 1932) for use by the user GUI ( 1910) in communicating with the SGPC ( 1921). Exemplary Peer-to-Peer (Push) Mode Method Embodiment ( 2000). Stability—A SGPC buffers/isolates its subnet from the change of the home gateway by monitoring and adapting to the latter. Home gateway tends to change its IP address or its communication channel from time to time.
For example, the IP address assigned by the ISP (Internet service provider) may change, and the communication channel may change to a new one due to the existing channel having too much interference. The SGPC constantly monitors the change and switches to the new communication channel if necessary to keep the communication with the network always enabled. Flexibility and Speed—Because the subnet is isolated from the change of the main home network, a static IP address can be used for a SGPC to simplify the implementation of the communication of the subnet. For example, a consumer with a laptop or smartphone can easily access a SGPC or any device in the subnet. By contrast, it is difficult to access a device in the main home network due to its dynamic nature. Additionally, it is faster to directly access a subnet from a PC without “competing” with other traffic over the gateway or Internet.
With these advantages, a SGPC provides a home automation system or energy management system that is cost effective and configurable to be both service provider and consumer friendly. Consumers can access or control it at home or away with a smartphone over Internet DIRECTLY.
They do this without the “sniffing” of a utility company and they have a full control of what they do. This direct path also increases the speed of the communication.
If they choose, they can also have the utility company or a service provider manage the SGPC for them. Many consumer devices, when turned off, still consume the standby energy, usually 5%-8% of the normal power consumption. This energy is called vampire energy, and can add up to significant amount. Consumers can specify that when vampire energy is detected, turn off the switch. Vampire energy can be detected by the current dropping below certain threshold, which is configurable by consumers. For example, when the current drops 80% for an extended period as detected by the energy measurement unit, vampire energy is detected.
Analysis of Energy Consumption. Utility companies have the energy cost profiles for enterprises and residential homes based on their smart meter feedbacks.
These profiles are available to consumers in some format, for example, in a form of “time of day vs. Energy cost” or “the amount of energy consumed vs. Energy cost”. This information can be found in utility bills for example.
Consumers can input the energy cost profile into a SGPC, and set the switch to automatic mode. The SGPC will make decision to turn on and off the switch(s) based on. 1 A server on the Internet keeps track of the IP addresses and port number by which to communicate with a SGPC. 2 The SGPC periodically sends a message to the above mentioned server, whereby the IP address and the port number of the message is retrieved and stored by the server in its database.
3 Additionally, SGPC sends the same message for the same purpose as in Feature 2 based on events. These events include IP address change, or port number change, among other things. 4 Alternatively, the server periodically sends a “keep alive” message to a SGPC, and updates its data base with the information (i.e., IP address and port number) retrieved from the return acknowledgement messages. 5 When a device away from home intends to communicate with the SGPC via Internet, it requests the IP address and port number from the server, and communicates with the SGPC directly. For information purposes, the messages will be sent over the Internet to the home gateway, which will forward them to the SGPC over WiFi communication inside the home.
In the reverse path, messages will start at SGPC, travels over the WiFi home network to the home gateway, which will send it to Internet back to the user. Access From Anywhere At Home Or Away—Peer-to-Peer Mode. 6 Alternatively, an Internet device can be registered with a SGPC in terms of an address (e.g., an email address for a tablet, a phone number for a smartphone).
7 The SGPC is then configured to send email or text messages to the devices mentioned in Feature 6. The messages contains necessary information, including IP address and port number, but is not limited to this information. 8 Based on the message in Feature 7 (the IP address and port number), a user can directly communicate with the SGPC. In this case, the device needs not go to a server to fetch the IP address and port number for communicating with the SGPC. Access From Home—Direct Mode.
12 A SGPC has its own subnet with static IP address. This is in contrast to the main home network, where a device's IP address is assigned dynamically by the gateway, and consumers usually have no control over the IP address (which can be changed without any notice) and have difficulty to directly communicate with it. 13 The subnet mentioned in Feature 12 communicates with main home network through SGPC. This is one reason this automation device is termed a gateway power controller. 14 A SGPC can join a subnet “gatewayed” by an earlier deployed SGPC, and has its own subnet, as generally illustrated in FIG. Adaptability to the Dynamic Nature of Home Networks. 20 A SGPC can be configured to communicate with other SGPCs to coordinate activities.
21 A SGPC can be configured to communicate with other sensors capable of WiFi communication, and use the sensor data as a base for scheduling a switch (see Feature 17). For information purpose, because a SGPC is an AP, most WiFi sensors configured as WiFi STA can communicate with it. When SGPC contains a ZIGBEE® module, ZIGBEE® based sensors can communicate with it. Push Information/Notification To Consumers. 25 A SGPC keeps track of the energy usage profile of the connected devices in terms of the duration and time of switch-on, and the energy consumed over a preset interval of time (e.g., a month), and provides the historical data in some format (table or histogram) 26 A SGPC can provide suggestions/guidelines/warnings based the historical data mentioned in Feature 25 and some rules. For example, a rule can be “avoid use this device between 6:00PM and 8:00PM for n days when the energy consumed so far is above m”.
A warning can be “You are charged at $xxx/KW-h due to xxx”. 27 These suggestions/guidelines/warnings can be subscribed by consumers as described in Feature 22.
User Interface. Line Power Interface ( 0901)-As detailed in FIG. 10 ( 1000), the input outlet brings 110V AC in through the fuse and split into two paths.
The first path converts the AC voltage to a DC voltage by 4-diode bridge rectifier. A transformer steps down the voltage to the level for further regulation. DC regulator (U3) provides +5VDC supply for the remaining circuits of the unit. The second path brings 110V AC voltage forward to the output socket via a power relay in the power switch ( 0904) by the output voltage is controlled as detailed in FIG.
Wireless Communications Interface ( 0903). As detailed in FIG. 12 ( 1200), a wireless transceiver receives the commands from the computer or/and other WiFi or wireless device.
The received command via the wireless receiver interface (not shown) will provide a logic signal (SWITCH) to turn on/off the transistor switch (Q 1). Q 1 controls the on/off position of the power relay in the power switch circuitry ( 0904) based on commands from the PMCU and may optimally be implemented using bipolar or MOS fabrication technologies. ZIGBEE® Wireless Interface ( 0905). As generalized in FIG. 8 ( 0800) and detailed in FIG.
13 ( 1300) and FIG. ( 1400), the SGPC ( 0810) may incorporate a ZIGBEE® interface ( 0814) the overall SGPC design to permit heterogeneous wireless networks using SGPCs to communicate with a wide variety of existing home automation wireless networks. While a wide variety of embodiments of this wireless interface are anticipated, a preferred embodiment incorporates the use of a Texas Instruments model CC2531 ZIGBEE® communications controller as generally illustrated by the block diagram of FIG. 13 ( 1300) and exemplary implementation schematic of FIG. As generally illustrated by the exemplary flowcharts depicted in FIG. 25 ( 2500)- FIG.
28 ( 2800), the present invention anticipates that the SGPC will in many preferred embodiments permit power control switching to be configured by a user using a graphical user interface. These switch configuration interfaces may include manual switch scheduling ( FIG. 26 ( 2600)), vampire energy switching ( FIG. 27 ( 2700)), and/or event-based switching ( FIG. Actual switch control implementation after this configuration process is complete is generally illustrated in FIG. 29 ( 2900)- FIG.
Switch Control Execution Method ( 2900)-( 3200). As generally illustrated by the exemplary flowcharts depicted in FIG. 29 ( 2900)- FIG. 32 ( 3200), the present invention anticipates that the SGPC will in many preferred embodiments execute power control switching to support manual switch scheduling ( FIG. 30 ( 3000)), vampire energy control ( FIG. 31 ( 3100)), and/or event-based switching control ( FIG. Associated configuration methodologies associated with these switch control execution flows are generally illustrated by the flowcharts in FIG.
25 ( 2500)- FIG. Energy Analysis Configuration Method ( 3300). As generally illustrated by the exemplary flowcharts depicted in FIG.
35 ( 3500)- FIG. 40 ( 4000), the present invention anticipates that the SGPC will in many preferred embodiments incorporate a variety of communication methodologies and protocols to enable the SGPC to “bridge” Internet and local home automation networks. 35 ( 3500) illustrates an exemplary flowchart depicting a local WiFi communication method to permit message routing in a SGPC network. 36 ( 3600) illustrates an exemplary flowchart depicting an Internet proxy server method to permit message integration and routing external to a SGPC network.
37 ( 3700) illustrates an exemplary flowchart depicting an addressing update method to address updating of devices external to a SGPC network. 38 ( 3800) illustrates an exemplary flowchart depicting SGPC message routing method.
39 ( 3900) illustrates an exemplary flowchart depicting a communication decision tree method to select the appropriate message transport methodology within the SGPC network. Exemplary Random Web Request Proxy Server Method ( 4000). The present invention anticipates the use of a methodology to permit a proxy server to remain connected with a SGPC within a home automation network that is located within a home gateway.
This configuration permits random web requests to pierce the home gateway firewall using information provided by the SGPC and maintained on the web proxy server. As generally illustrated by the flowchart in FIG. 40 ( 4000), this preferred exemplary proxy server method embodiment can be generalized comprising the following steps:. 41 ( 4100) illustrates a typical SGPC web page user interface that permits users to monitor status and configure the SGPC. As can be seen in this GUI dialog, the devices controlled by the SGPC may be represented by graphical icons, given identifying names, be provided a real-time status indicator, be available for on/off switch activation or scheduling, and be associated with real-time power consumption curves. On the right hand side of the dialog box a house wide information and setup configuration controls.
The “download software” icon allows consumers to download software to their devices. The “Guidelines and Tips” icon opens a window that makes suggestions on energy usage. The “Edit Account Setting” icon allows password changes, etc. The “Add A New Device” icon allows adding devices from a list of all the available SGPC controlled devices to the list on the left of the GUI. A user may or may not want to put all SGPC controlled devices on the GUI.
When adding a new device, the user may assign a name and an icon to the device, as shown in the FIG. The “Share” and “Energy Manager” icons are discussed below. On the left hand side of the dialog screen associated with each device are buttons which allow control, setup, and monitoring of the device. Some of the buttons are self-explanatory. “Action” brings the device down or up depending on the direction of the arrow.
“Help” pops up a window providing information on the device. The “Data” and “Schedule It!” icons are discussed below. 43 ( 4300) generally illustrates an exemplary device configuration dialog used to configure switched devices and monitor switch triggering events/sensors. Selecting the event icon button (the notebook symbol) associated with a SGPC controlled device (for example, a printer) activates this dialog screen.
In this window the user may associate the dependencies between the devices (i.e., a printer) (and their measurements/status) and the SGPC controller. For example, the user may choose “Thermostat”, and its “temperature” measurement, define a condition from a list of predefined conditions, for example, “greater or equal”, define a threshold, for example, “98 degrees”, and finally, define an action, say, “down off”.
Therefore, in this example, the printer will turn off, if the thermostat's measured temperature is greater or equal to 98 degrees. Note that this popup also allows an action to be associated with a status change. The dependent devices (the thermostat for example) may also be part of the devices listed on the main GUI page. As generally illustrated herein, the system embodiments of the present invention can incorporate a variety of computer readable media that comprise computer usable medium having computer readable code means embodied therein. One skilled in the art will recognize that the software associated with the various processes described herein can be embodied in a wide variety of computer accessible media from which the software is loaded and activated.
Pursuant to In re Beauregard, 35 USPQ2d 1383 (U.S. 5,710,578), the present invention anticipates and includes this type of computer readable media within the scope of the invention. Pursuant to In re Nuijten, 500 F.3d 1346 (Fed.
Patent application Ser. 09/211,928), the present invention scope is limited to computer readable media wherein the media is both tangible and non-transitory. A power control system/method implementing Internet based access to hybrid home automation networks has been disclosed.
The system utilizes a smart gateway power controller (SGPC) to selectively switch an AC power source to a load device under control of local or remote network commands that may be routed through a variety of network interfaces and protocols present within a home or other structure-local communications network. SGPC configurations may be nested within a home automation network to permit separation of control for load devices within a common home automation environment.
