Application Of Wireless Sensor Network To Intelligent Home System

With the development of information technology including computer, communications, network, micro-electronics, integrated circuit, enormous changes happen in IT hardware environment and software environment. This changes cause the information space which the communications and the computer constitutes and people life of the work physical space to merge into an integral whole gradually. The Ubiquitous Computing thought is produced under this kind of background. The wireless sensor network node take the Ubiquitous Computing as one kind of information equipment, and has been already allowed to build the intellectualized computation environment which might nimbly order—Ubiquitous Computing environment quickly.Taking the Intelligent Home System as the research background,the origin and development of the wireless sensor network and the Intelligent Home System are introduced firstly. Then, one kind of wireless network technology, ZigBee, is analysed. Then the present Intelligent Home System insufficiency and the indoor environment challenge to the wireless sensor network technology are analyzed specifically. The new intelligent home network concept based on the wireless sensor network is proposed. The electrical appliance interconnection problem in the indoor environment is solved practically. The wireless sensor network node is designed stressly, and its four partial detailed designs are elaborated, including each chip interface. Aming at the problem the energy conservation of the node, the new resolving way from node to system is brought forward. The network layer core protocol is introduced, and simulation is made too. Finally, the new network is built, and Intelligent Home System each part is presented. The magnificent prospect of Intelligent Home System based on the wireless sensor network is forecast.
