Abstract:In order to deal with the demand of a large number of multi-function and high precision automatic control functions in a new generation of smart home system,an intelligent switch controller based on ARM & WIFI wireless communication technology is designed. Based on the WIFI wireless technology,users can use mobile smart devices such as Android smart phones or tablet computers to control of the household electrical equipment such as the lighting system in real-time, with the help of the client software on the devices. Using various sensor modules to monitor the operating environment of the controller and the controlled equipment, users can also view the relevant information through the mobile client software. The TFT LCD screen is used to build the user interaction display module, and the screen can dynamic display the relevant information in real-time, so as to convenient the user's daily use and enhance the user's intuitive experience.The experimental results show that the proposed intelligent switch controller based on the ARM & WIFI communication, can realized the intelligent dynamic control for the controlled equipment. The controller has the advantages of simple structure, flexible operation, quick response and diversified control functions, and its application prospect is extensive.
