The Design Of System For Smart Home Based On Zigbee

China has made great achievements in economic and social reforms, while the requirement of a comfortable, convenient and safe household life of intelligent for people was put forward. However, there has not been a normative technical standard as the smart home always improved with new technology. At present, a number of emerging wireless sensor network(WSN) technologies have brought a new dawn to the enterprises which are exploring in the field of smart home. With the country making more plans and support for smart home at the strategic level, a large number of new companies emerged. Especially, the traditional home appliance enterprises and Internet technology giant alliance mode, frequently reported by the media. The popular concept of smart home has been pushed to the attention of the industry.After making the analysis about the history profile of development and the present situation of domestic and foreign smart home, this paper put forward a kind of smart home system design based on wireless sensor network of Zigbee. As nowadays popular technology of internet of things, Zigbee is ideal for smart home application with its incomparable low-power and large-scale networking capability. The paper presented the characteristic and the communication protocol of Zigbee in detail, and then designed the hardware circuit and the network program. In order to connect the WSN and the Interenet to realize the remote control, this paper made detailed design on the hardware of home gateway and the transplant of the network communication protocol. After that, the paper selected the current market share of the first android smart phone as the monitoring terminal. And designed the android software of related functions according to the three kinds of monitoring mode-control equipment, access to information and information interaction. At the same time, the paper also designed the sever software which aims at realizing the communication between home sensor network and the monitoring terminal. Finally, the related hardware and software development and debugging was completed relying on the advanced condition of key laboratory of robot in Shenzhen Institute of advanced technology, Chinese academy of sciences. Test results shown the realization of basic design criterion and proved the rationality of the system design.
