Scalable smart home network control system

Abstract

An expandable smart home network control system, in order to overcome the lack of zigbee and bluetooth communication distance, to achieve a larger coverage, and in order to adapt to the communication mode of smart phones, tablet computers, and home wireless gateways with very high penetration rates, control terminals, The controller and the home wireless gateway use WiFi to communicate and control the operation of multiple household appliances, which is characterized in that it includes: a control terminal that issues control instructions for controlling household appliances; Household appliances; wherein, the controller includes: a WiFi communication module, a routing module, and an extended function module; the control terminal includes a device management module, a control command module, a movement detection module, a routing module, and a WiFi communication module; the control terminal Running a common routing protocol with the routing module of the controller.

Description

technical field [0001] The invention relates to a control system for household appliances, in particular to an expandable intelligent home network control system for intelligently controlling various household appliances. Background technique [0002] With the development of Internet of Things technology, smart home has broad development prospects. However, how to connect the infrared remote control, radio frequency control, and Bluetooth control of existing traditional home appliances with the current networked control mode is a problem that affects the realization of smart home. The general solution is to integrate multiple control modules on one controller: for example, the infrared remote control unit is used to control infrared remote control appliances such as TVs, air conditioners, and electric fans, the radio frequency remote control unit realizes the control of radio frequency control appliances, and the sound wave control unit controls Voice-activated lamps and ot...

AI Technical Summary

Problems solved by technology

However, the existing smart home controllers have the following deficiencies: 1. Cool-Remote and broadlink WiFi learning type air-conditioning TV universal remote control integrate infrared control and radio frequency control modules, but cannot support zigbee, Bluetooth and other devices. Single; a WiFi network-based Web smart home control system (public number CN103792925A, 2014.05.14) built-in WiFi core unit, infrared remote control unit, lighting control unit and security alarm unit, with many built-in functions, consumers can not according to their own needs Choice, some functions are not necessary, resulting in an unnecessary increase in cost

2. None of the above-mentioned controllers has a routing module and cannot be controlled by networking. Smart terminals can only communicate with smart home control nodes through home WiFi gateways or smart home control centers. In rooms with weak WiFi signals, they cannot automatically adapt to changes based on physical location. Match the strength of the control signal, resulting in extended control signal transmission time, or even failure to transmit

3. A Bluetooth-based smart home control system (public number CN102799152A, 2012.11.28) has a limited communication distance; the main controller of Shangji Smart Z-Home smart home is based on zigbee, and the smart phone cannot communicate directly with the controller

4. The existing design cannot provide feedback on the control results of the controlled household appliances, making it impossible for people to understand the control effect in real time in the remote terminal
