The emergence and popularity of mobile computing has made portable electronic devices—due to their compact design and light weight—a staple in today's marketplace. Mobile devices such as smartphones involve advance computing functionality and are utilized for common tasks including email, internet surfing, gaming, and media capture/playback. Meanwhile, home automation systems provide centralized control for lighting, HVAC (heating, ventilation and air conditioning), appliances (such as refrigerators and dishwashers), and similar systems. However, these systems are difficult to upgrade as they typically have product lifecycles of approximately ten years. As a result, home automation technology is usually many years behind the technology of the latest mobile device.

Traditional home automation systems involve the use of a number of complex controllers and sensors. Prior solutions include implementation of a power line control protocol that allows communication between transmitters and receivers of various appliances by sending signals over existing house wiring. Still further, other systems utilize motion-activated sensors such that a light turns on or a surveillance camera activates upon someone entering a room or area. Such systems require the user to plug the appliance device or system into a proprietary module and undertake a timely and sometimes complex pairing process for interfacing the devices with a separate remote controller. Moreover, each system simply involves one-way communication between the remote controller and module and does allow for status updates or similar information to be transmitted from the appliance device/system back to the remote controller. Therefore, there is a need in the art for a simplified and robust home automation that offers two-way communication between devices.
Examples of the present invention disclose a system and method for home automation using a mobile device. According to one example embodiment, near filed communication (NFC) or any other short-ranged wireless communication protocol is utilized for allowing a mobile device to interact with various systems and appliances within the home environment. For instance, the mobile device may send process requests to an intermediary device controller installed within a target home appliance device. The process request may be executed locally on the device with status update information transmitted back to the mobile device.
Referring now in more detail to the drawings in which like numerals identify corresponding parts throughout the views,
Still further, each home appliance device 120a-120c includes a wireless transceiver 125a-125c and device controller 125a-125c for facilitating communication with the mobile device. As will be used herein, home appliance devices represent any electrical or mechanical appliance, system, or machine used to perform a household function (e.g., oven for cooking, dishwasher for cleaning, light fixtures for illumination, refrigerator for storage, and HVAC for cooling/heating the home environment, etc.). Device controller 125a-125c may be a device or module electronically coupled to the home appliance device 120a-120c or an integrated unit of the home appliance device 120a-120, and is configured to execute programming instructions and control operations on the home appliance device such as controlling the temperature of a HVAC or toggling the light system on and off. According to one example embodiment, the mobile device 110 may establish communication with the device controller 125a-125c of an associated home appliance device 120a-120c respectively, via data transmission from the wireless transceiver 104 of the mobile device 110 to the wireless transceiver 123a-123c of an associated home appliance device 123a-123c.
According to one example, the wireless transceivers 123a-123c may be implemented within the device controller 125a-125c of the associated home appliance device 120a-120c. Additionally, a master controller 130 may be implemented between the mobile device 110 and device controller 125a-125c of each home appliance device 120a-120c. In such a configuration, the mobile device 110 would communicate directly with the master controller 130. Based on the information received from the mobile device 110, the master controller 130 would then manage the transmission of data to/from each home appliance device 120a-120c and device controller 125a-125c respectively. Furthermore, communication between the individual device controllers 125a-125c and the master controller 130 could be accomplished via radio frequency (RF), power lines, wireless fidelity, or any other communication interface scheme.
As an example of home automation with respect to a lighting system, a device controller may be included with or connected to each lighting fixture 220c. The device controller could be integrated with the lighting system or placed in electrical contact (e.g., power cord interface) with each lighting fixture 220c. According to one example, the operating user could program the lighting through the mobile device 210 enabled with wireless communication (e.g., near field communication). Specifically, the associated device controllers are configured to turn the lights 220c on and off based on process requests or instructions received from the mobile device 210 or master controller. When the mobile device 210 is present within a communicable field of the controller (master controller or device sub-controller) or physically tapped against a controller, the mobile device would gain access to the home appliance device thus allowing the user to set the brightness of the lighting fixture using the mobile device 210. Moreover, settings of the lighting system 220b could be automated such that lights automatically come on or turn off whenever the mobile device 210 and operating user enter or exit a room.
Similarly, the HVAC or thermostat 220c of the house 205 may also be controlled via the mobile device 210. In one example, thermostat control could be given to the operating user whenever the mobile device is physically tapped against the thermostat, or whenever the mobile device is placed within a communicable distance with the HVAC system such that credentials may be exchanged between the two devices (mobile device 210 and HVAC 220c). According to one example, the temperature of each room could be set intelligently according to preset preferences and the location of the mobile device 210 and operating user. For example, the device controller may automatically cause the thermostat to set to a temperature of 72° upon detecting the presence of the mobile device within a communication field (e.g., less than 20 cm) of the device controller or master controller.
If a service or process request is made by the user operating the mobile device in step 406, then the process request is sent to a destination appliance device via the wireless communication means in step 408. As used herein, a process request represents an action or operation to be executed by the home appliance device such as updating the inventory data of a refrigerator, changing the environment temperature of a HVAC, changing the cooking time of an oven, or simply turning a particular light fixture on or off. Thereafter, in step 410 the destination home appliance device executes an operation associated with the received process request and then updates the status information, which may be sent to the mobile device in step 412. For example, upon establishing communication between the mobile device and a smart oven, the user may send a process request to adjust the baking temperature from 375° to 425°. The device controller of the smart oven will execute an operation (i.e., temperature adjustment) associated with the received request and may then send the user an update of the estimated cook time (status information) based on the new temperature.
Embodiments of the present invention provide method and system for providing home automation using a mobile device. Moreover, many advantages are afforded by the home automation system and method in accordance with examples of the present invention. In particular, the home automation system can help integrate several home appliance devices with one centralized control interface (i.e., mobile device) while contemporaneously providing two-way communication between the device and central interface. Due to the accessibility of the walls, power outlets, storage rooms and the ability to make design changes specifically to accommodate the desired automation functionality, home automation was generally only implemented within a new home during construction. However, the configuration of the present examples allows for home automation integration in existing homes with minimal effort and little to no technical expertise. Furthermore, a simplified and efficient home automation system will provide increased quality of life for the elderly, disabled, and other persons who might otherwise require caregivers or institutional care.
Furthermore, while the invention has been described with respect to exemplary embodiments, one skilled in the art will recognize that numerous modifications are possible. For example, although exemplary embodiments depict a smartphone as the mobile device, the invention is not limited thereto. For example, the mobile device may be a netbook, a tablet personal computer, or any other portable electronic device enabled with short range wireless communication.
Furthermore, the home appliance devices available for control via the mobile device may include numerous additional devices than those discussed above and depicted in the accompanying figures. Thus, although the invention has been described with respect to exemplary embodiments, it will be appreciated that the invention is intended to cover all modifications and equivalents within the scope of the following claims.
