Design And Implementation Of Smart Home System Based On ARM

With the development of society informatization and the improvement of people's living standard, people's demands for the living environment, security, energy conservation are increasing. Technologies on the smart home have attracted a lot of attention from the experts and researchers.In order to realize the functions of the unified management and wireless transmission of the smart home system, it that adopts the embedded system as the hardware platform of the control centre introduces ZigBee technology in the domestic interior network and gradually realizes the network change from wired transmission to wireless transmission. On the basis of the intensive study and analysis of development situation and corresponding technology of the smart home, it proposes overall structure of the smart home which includes user management system, control centre and wireless home network.According to the system design, it that studies on the main modules is closely around the functional requirement in the detailed design scheme. First, it carefully analyses the control centre, coordinator node, terminal node, infrared detector and so on. It puts forward the detailed the hardware design in accordance with each module function. Second, according to the hardware design of each module, it that deeply analyses the information exchange procedure among the control centre, coordinator and terminal node carries out the detailed software design of each module. On the basis of the control centre, it that establishes the control platform of the smart home realizes the wireless transmission in the domestic interior network, playing a big role in the function of system management, information transmission of the control centre to a large extent. Third, it monitors the temperature in different living environment through Web server based on system function, and it achieves the fixed position function of the security alarm by hardware circuit.
