20180270076
This Patent Application claims priority to India Provisional Patent Application No. 201741009241 filed Mar. 17, 2017 entitled “SMART NETWORKING OF TRADITIONAL APPLIANCES,” and assigned to the assignee hereof. The disclosure of the prior Application is considered part of and is incorporated by reference in this Patent Application.
This disclosure generally relates to the field of communication, and more particularly to connecting appliances in a communication network.
Developers have promoted the concepts of “smart” appliances which allow users to control or automate some operations of commonly-used appliances via a network. For example, consumers who desire home automation may purchase products such as smart light bulbs or other types of smart appliances (also marketed as network-connected appliances). However, an appliance may be in a location that prevents it from easily being added to the network. For example, the appliance may be placed in a location that causes it to have a weak wireless signal to a wireless network or the appliance may be in a location that does not have wireless coverage at all. It may be inconvenient for a consumer to move the appliance or enhance the wireless coverage for a wireless network. While some new smart appliances may have multiple network interfaces, such appliances may still be relatively expensive or unavailable in some markets. Furthermore, there are inherent disadvantages associated with replacement of existing appliances with newer appliances. Such disadvantages include the waste disposal of discarded appliances, byproducts of manufacturing replacement appliances, and costs to consumers for replacement of multiple appliances in a physical location. Additionally, deployment of smart technology within an environment may be cost prohibitive, difficult for consumers, or unavailable in some markets.
The systems, methods, and devices of this disclosure each have several innovative aspects, no single one of which is solely responsible for the desirable attributes disclosed herein.
One innovative aspect of the subject matter described in this disclosure can be implemented in an appliance interface apparatus for networking a traditional appliance. The appliance interface apparatus may connect the traditional appliance to a power source via an appliance socket of the appliance interface apparatus. The appliance interface apparatus may establish, via a first network interface of the appliance interface apparatus, a first communication link with a smart appliance controller in a network. The appliance interface apparatus may establish a second communication link with a control circuit for controlling the traditional appliance. The appliance interface apparatus may receive, via the first communication link, a command from the smart appliance controller. The appliance interface apparatus may send a signal via the second communication link to the control circuit. The signal may control an operation of a traditional appliance in accordance with the command.
In some implementations, the appliance interface apparatus may include a processor for receiving the command. The processor may be powered by the power source.
In some implementations, sending the signal for controlling the operation of the traditional appliance may include translating the command from a first command protocol of the network to the signal for use on the second communication link.

The instructions, when executed by the processor may cause the appliance interface apparatus to establish, via the first network interface, a first communication link with a smart appliance controller in a network. The instructions, when executed by the processor may cause the appliance interface apparatus to establish a second communication link with a control circuit for controlling the traditional appliance. The instructions, when executed by the processor may cause the appliance interface apparatus to receive, via the first communication link, a command from the smart appliance controller, and send a signal via the second communication link to the control circuit. The signal may control an operation of the traditional appliance in accordance with the command.
In some implementations, the processor may be powered by the power source.
In some implementations, the instructions to send the signal for controlling the operation of the traditional appliance may include instructions which, when executed by the processor, cause the appliance interface apparatus to translate the command from a first command protocol of the network to the signal for use on the second communication link.
In some implementations, the instructions to receive the command may include instructions which, when executed by the processor, cause the appliance interface apparatus to receive the command from the smart appliance controller via one of multiple network interfaces capable of receiving the command.
In some implementations, the appliance interface apparatus may include a second network interface for establishing the second communication link to the traditional appliance.
In some implementations, the first network interface is a PLC interface and the second network interface is a WLAN interface.
Another innovative aspect of the subject matter described in this disclosure can be implemented in a computer-readable medium having instructions stored therein. The instructions, when executed by the processor may cause the appliance interface apparatus to establish, via the first network interface, a first communication link with a smart appliance controller in a network. The instructions, when executed by the processor may cause the appliance interface apparatus to establish a second communication link with a control circuit for controlling the traditional appliance.

Details of one or more implementations of the subject matter described in this disclosure are set forth in the accompanying drawings and the description below. Other features, aspects, and advantages will become apparent from the description, the drawings, and the claims. Note that the relative dimensions of the following figures may not be drawn to scale.
Like reference numbers and designations in the various drawings indicate like elements.
The following description is directed to certain implementations for the purposes of describing the innovative aspects of this disclosure. However, a person having ordinary skill in the art will readily recognize that the teachings herein can be applied in a multitude of different ways. The described implementations may be implemented in any device, system or network that is capable of transmitting and receiving RF signals according to any of the IEEE 16.11 standards, or any of the IEEE 802.11 standards, the Bluetooth® standard, code division multiple access (CDMA), frequency division multiple access (FDMA), time division multiple access (TDMA), Global System for Mobile communications (GSM), GSM/General Packet Radio Service (GPRS), Enhanced Data GSM Environment (EDGE), Terrestrial Trunked Radio (TETRA), Wideband-CDMA (W-CDMA), Evolution Data Optimized (EV-DO), 1xEV-DO, EV-DO Rev A, EV-DO Rev B, High Speed Packet Access (HSPA), High Speed Downlink Packet Access (HSDPA), High Speed Uplink Packet Access (HSUPA), Evolved High Speed Packet Access (HSPA+), Long Term Evolution (LTE), AMPS, or other known signals that are used to communicate within a wireless, cellular or internet of things (IOT) network, such as a system utilizing 3G, 4G or 5G, or further implementations thereof, technology.
A “smart” appliance is any appliance which can be controlled, automated, or managed using a network-based command protocol. Some manufacturers may market smart appliances as network-connected appliances, Internet-of-Things (or “IOT”) devices, smart home devices, and the like. A traditional appliance (such as a coffee machine, refrigerator, lamp, washing machine, dishwasher, toaster, or the like) is any appliance that was not traditionally intended to operate on a network. Unless the traditional appliance can be added to the network, the traditional appliance cannot by controlled, automated, or managed by a network-based command protocol. In some implementations, a traditional appliance may be equipped with a control circuit which could be controlled by a signal. However, the traditional appliance may not have network interface for communicating via a network or may be in a location where wireless network communication is unstable, unavailable, or unreliable. For example, the wireless network communication may be degraded as a result of very poor signal strength. Network-enablement of traditional appliances may enable smart control over the traditional appliance. In this disclosure, implementations will be described in the smart home automation environment. However, some other implementations may be used in commercial locations, manufacturing locations, or any environment in which smart appliances might be useful. It may be costly for a consumer to replace traditional appliances with newer or upgraded smart appliances. Providing a network interface with common command protocol may enable a user to enjoy smart control features on a traditional appliance while reducing cost and complexity.
In this disclosure, an appliance interface apparatus enables network-based control over a traditional appliance. The appliance interface apparatus can establish a first communication link with a smart appliance controller in a network. The appliance interface apparatus can establish a second communication link with a control circuit of the traditional appliance. The appliance interface apparatus can receive a command (such as a home automation command) from the smart appliance controller and send a signal to the control circuit tocontrol an operation of the traditional appliance in accordance with the command. Using the techniques in this disclosure, a traditional appliance (such as a traditional light bulb) can be controlled by a smart appliance controller.
In some implementations, an appliance interface apparatus may establish the the first communication link using a wireless wide area network connection. For example, some telecommunications companies are deploying wireless broadband technology (such as fifth-generation, or 5G, wireless communication technology) to provide wireless broadband connectivity to the Internet. An appliance interface apparatus that connects to the Internet using a wireless broadband connection may serve as a gateway for other appliance interface apparatuses in a location. For example, a group of appliance interface apparatuses may communicate with each other using a powerline communication mesh topology, while one or more of the appliance interface apparatuses also may have a wireless broadband connection. Such a configuration can enable control of appliances in a location via a remote Internet connection even if the user is not near the local network where those appliances are located. Furthermore, a group of appliance interface apparatus may form a mesh network with multiple network connections for increased resiliency and coverage within an environment.
In some implementations, an appliance interface apparatus may enable control of disparate appliances. For example, an appliance interface apparatus may implement a command translation utility to translate a command (such as a home automation command) from the smart appliance controller into a signal that is specific to the type of appliance that it supports. In some implementations, the command translation utility may be referred to as a hardware abstraction layer and may downloaded as a “hosted application” on the appliance interface apparatus. Using a hosted application may be useful when replacing an appliance because a different command translation utility can be used for the new device while maintaining the same smart appliance controller.
Particular implementations of the subject matter described in this disclosure can be implemented to realize one or more of the following potential advantages. For example, consumers could use traditional applianceswith features associated with smart appliances. In some implementations, consumers may continue to utilize a less expensive or existing traditional appliance while controlling the traditional appliance as if it was a smart appliance. For example, a consumer could install an appliance interface apparatus to enable a common network-based command protocol via a control circuit associated with a traditional appliance. Connectivity may be improved through the use of mesh networking and wireless broadband connectivity. Control of traditional appliances also may be enhanced due to the command translation capabilities of an appliance interface apparatus.
The system 100 also shows a second appliance 135 which receives power from the powerline medium 112. The second appliance 135 (such as a “smart light bulb”) may be capable of receiving a command from a client device 180 because it may have a wireless network interface. For example, the client device 180 may send a command via a wireless link 162 (such as Wi-Fi or Bluetooth®) to the second appliance 135. The second appliance 135 may have communication capability built into the second appliance 135. To take advantage of the smart home automation, a consumer might replace an existing traditional appliance (such as the first appliance 125) with a new appliance (such as the second appliance 135). However, a cost-conscientious homeowner may not want to replace traditional appliances with new appliances. Furthermore, there may be many different types of traditional appliances (such as various brands or types of equipment) within a home or commercial environment. The ability to quickly network traditional appliances and use a standard command protocol within the home or commercial environment may increase the rate of adoption for smart controller technology and improve compatibility or consistency for controlling the different types of traditional appliances.
As found in many homes and businesses, a local network may be present in the system 200. For example, a router 210 (also known as a gateway) may provide network connectivity between client devices and a network 220. In the system 200, client devices 180, 230 are communicatively coupled to the router 210. A first client device 180 (shown as a mobile device) may have a WLAN communication link 242 to an access point 240. The access point 240 may be separate from the router 210 or may be integrated (or collocated) with the router 210. A second client device 230 (shown as a stationary computer) may have a physical communication link 232 (such as Ethernet) to the router 210. The appliance interface apparatus 250 also may have a WLAN communication link 252 via the access point 240 to the router 210.
In
A PLC network communication link 340 may be used by the appliance interface apparatus 250 to communicate via the powerline medium 112 (and PLC interface 330) to the router 210. The router 210 may include a home automation platform for forwarding commands to the appliance interface apparatus 250. Upon receiving a command from the network 220 or either of the client devices 180, 230, the router 210 may forward the command via the PLC interface 330 and PLC network communication link 340 to the appliance interface apparatus 250.
In some implementations, the appliance interface apparatus 250 may have more than one network interface. For example, the appliance interface apparatus 250 may be capable of using either or both the PLC network communication link 340 and the WLAN communication link 252, depending on network conditions. If the WLAN communication link 252 is not stable or has a weak signal, the appliance interface apparatus 250 may select the PLC network communication link 340 to communicate with the smart appliance controller. In some implementations, the appliance interface apparatus 250 may establish a different communication link (not shown) with the control circuit that is different from both the PLC network communication link 340 and the WLAN communication link 252.
In some implementations, a group of appliance interface apparatuses (not shown) may coordinate with each other to form a mesh network using one or more communication links. For example, some appliance interface apparatuses may support PLC and WLAN communication links, other appliance interface apparatuses may support PLC and wireless broadband connectivity, and so on. The group of appliance interface apparatus may coordinate with each other to form a mesh network with several types of communication links being supported. In some implementations, the appliance interface apparatuses may communicate using mobility management entity (MME) messaging to coordinate with each other to control different types of appliances through the mesh network.
In
The processor 410 also may utilize power from the power source 110. In
The processor 410 is configured to receive commands from a smart appliance controller via a network. The network interface 470 provides connectivity between the appliance interface apparatus 250 and the network. In some implementations, the network interface 470 may be a WLAN interface which communicates via an antenna 480. For example, the WLAN interface may be configured to implement Wi-Fi-based technologies described in the IEEE 802.11 standards. In some other implementations, the network interface 470 may be a PLC interface which communicates via a PLC connection 490 to the powerline medium 112. For example, the PLC interface may be configured to implement PLC standard-approved technologies (such as IEEE P1905.1 or various HomePlug standards). In addition, or alteratively, the network interface 470 may implement other types of networking (such as Ethernet, token ring, optical networking, light-based communication, short-range radio frequency communication, and the like). For example, the network interface 470 may conform to specialized standards or protocols for a particular environment (such as a manufacturing-specific network, or a in-vehicle network). In some implementations, the appliance interface apparatus 250 may include more than one network interface and may be capable of sending or receiving commands via more than one network communication medium. For example, the appliance interface apparatus 250 may include a second network interface 475 that uses a different communication technology to communicate with the control circuit (shown at arrow 477). The second network interface 475 also may communicate (shown at arrow 479) with a control circuit of another component (not shown) in the traditional appliance 255.
In implementations that utilize the dimmer circuitry 440, the appliance interface apparatus also may include a dimmer voltage regulator or a pulse width modular (PWM) for managing the amount of voltage or timing used by the dimmer circuitry 440. For example, the PWM (not shown) may be used between the processor 410 and the dimmer circuitry 440 or may be included as part of the dimmer circuitry 440. Using the dimmer circuitry 440, the processor 410 can control operation of the traditional appliance 255. For example, the processor 410 can manage the dimming level (also called brightness) of light produced by a traditional light bulb. Furthermore, various types of dimmer circuitry 440 may be utilized for specialized light bulbs, such as for a light emitting diode (LED) light bulb or a compact fluorescent light (CFL) light bulb. In some implementations, the power supply relay 430 may be omitted or replaced by the dimmer circuitry 440.
In some implementations, the traditional appliance 255 is coupled to the appliance interface apparatus via an appliance socket that is specific to a type of traditional appliance. For example, if the traditional appliance is a light bulb, the appliance socket may be a lightbulb socket. The control circuit also may be specific to the type of traditional appliance. For example, if the traditional appliance is a light bulb, the control circuit (such as the power supply relay) may be physically integrated into the light bulb holder. Other types of appliance sockets and control circuits may be used with different types of traditional appliances. In some other implementations, the traditional appliance may be an appliance with a power cable and power plug (such as a coffee machine, lamp, television, toaster, or the like) designed to plug into a traditional power socket). For example, the appliance socket may be a power socket into which the power plug is inserted. The appliance interface apparatus may be installed as a new wall power socket or may be inserted into an existing wall power socket. The control circuit may be integrated with the traditional appliance. For example, the control circuit may be included on a control board in a washing machine, dishwasher, oven, refrigerator, or the like. The appliance interface apparatus may be used to retrofit an existing traditional appliance by interfacing with a communication port of the control board. The appliance interface apparatus may add network-based communication to the existing control board. Furthermore, the appliance interface apparatus may provide translation of a command in a command protocol used by a smart appliance controller to a signal that is appropriate for the control circuit in the traditional appliance. In some other implementations, the traditional appliance may be a wearable accessory and the appliance socket may correspond to a power supply line for providing power to the wearable accessory. A person having ordinary skill in the art may readily conceive of other examples of traditional appliances and related power sources which may be controlled by an appliance interface apparatus.
There may be other components in the appliance interface apparatus 250, not shown in
At 525, the client device 180 sends a command associated with turning on the traditional appliance 255. The command is sent to the smart appliance controller 510. The smart appliance controller 510 forwards the command at 535 to the processor 410. In some implementations, the smart appliance controller 510 may be associated with multiple network interfaces and may receive or send commands over various network interfaces. The processor 410 receives the command and determines that the command includes an instruction to turn on the traditional appliance 255. In accordance with the command, the processor 410 may send a signal (at 545) to the control circuit 455 to cause the control circuit 455 to enable power. In the example of
In some implementations, the signal (at 545) may use a different communication protocol than the command. For example, the appliance interface apparatus 250 may establish a first communication link to the smart appliance controller 510 using a first communication protocol. The command may be associated with a command protocol and may be formatted for communication using the first communication protocol. The appliance interface apparatus 250 may establish a second communication link to the traditional appliance 255 that uses a second communication protocol. For example, the second communication protocol may be associated with a serial or parallel cable interface to the control circuit. The processor 410 may translate the command into a signal (at 545) that is specific to the second communication link and the control circuit. In some implementations, the appliance interface apparatus 250 may download a hardware abstraction layer (or command translation instructions) that are specific to the type of appliance to which the appliance interface apparatus 250 is coupled. For example, the appliance interface apparatus 250 may download the hardware abstraction layer (or command translation instructions) on-demand during onboarding a new type of appliance. In some implementations, the appliance interface apparatus 250 may detect the type of appliance based on communication via the second communication link to the traditional appliance 255.
In some implementations, the processor 410 may send an acknowledgment message (shown at 555) to the smart appliance controller 510. The smart appliance controller 510 may forward the acknowledgment message (shown at 565) to the client device 180.
In some implementations, the appliance interface apparatuses 750A, 750B, 750C may be in an area that has poor wireless coverage. The smart appliance controller (not shown) may communicate via the router 210 and the powerline medium 112 to the appliance interface apparatuses 750A, 750B, 750C. The appliance interface apparatuses 750A, 750B, 750C may bridge the communications via the powerline medium 112 to WLAN messages and relay the commands to a WLAN interface in a smart appliance (not shown) near the appliance interface apparatuses 750A, 750B, 750C.
