Abstract. A smart home system is designed in this paper. The hardware platform and software architecture are presented, and the key software solutions are stated. A smart home prototype system is developed to prove the adopted technologies,which can satisfy the smart home market and will lay the foundation for the future extension. Keywords: Smart Home, Visual Intercom, Multimedia.
1 Introduction With the research and development of sensor network in China, the smart home system has been endowed with the new meaning. What is the smart home life like? In the home equipped with the smart home system, the appliances, lighting and home theatre can be controled; the public information from the community can be received at real time; the community online mart service,remote health ware and express mail service can be provided more conveniently. If you are out of home, you can connect with the smart terminals by telephone,cell phone or internet to be aware of the using of appliances and monitor the situation of home; the visitor can leave message with voice and video; if the gas leak happens and a thief enters your home, the safety device can alarm automatically and shoot a picture of the thief,which can be sent to you instantly. When you are on the way home, you can open the air conditioner and hot water system in advance through your telephone. In a word, you can enjoy a more intelligent, convenient, and comfortable life with the smart home system[1,2,3,4,5,6]. According to the topological structure of the system, the smart home system can be divided into three types: american series, european series and korea series. The characteristics of american series products are as following: a controller is the center of the whole system, which has the strong function of assigning and controling multimedia signals and has the impressive touch screen user interface. This system can provide users with resplendent audio-visual enjoyment, which fits in with deluxe villas. But it also has shortcomings. This system relies on central controller so much that once the central controller fails, the whole system is prone to be paralyze, i.e. low liability. H.

The european series products adopt the non-controller dispersed control mode. Every module has its control program, which means that the malfunction of an individual device will not induce the failure of the whole system, i.e. high liability. But the european series products don’t have the ability of asigning and controling the video signals, the touch screen user interface of which is simple and the multimedia controling ability is weak. This type of products are fit for the middle and high class villa whose main function is control. The korea series products add some control functions to the visual intercom system such as lighting and curtain controling. The advantage is that such system has the ability of video transfering. But it also rel
