Design Of An Embedded Remote Monitoring System For Smart Home Based On Zigbee

With the rapid development of social economy and the increasing improvement of science and technology,people begin to have higher demands for living quality,and be in pursuit of intelligent,secure and efficient lifestyles,while people's home life styles start to get safer,more comfortable and intelligent.Due to the flaw of traditional smart home system and catering for the demands of modern home life,this paper studies the adoption of high-performance processor S5PV210,and on the basis of the Zigbee wireless network,to design a smart home system with better tailor ability and great convenience of installation.The main contents of this paper are as follows:(1)The design of the system scheme.Searching for and reading literatures and documents,are direct at the current situation of smart home development and people's requirements of smart home's comfort,security and efficency.The high-performance CPU S5PV210 of ARM Cortex-A8 structure works as the main control processor,making use of the Zigbee wireless network to reach data transmission between nodes,to make monitoring home and residential environment come true,by users' visiting gateway server.(2)The design of system's hardware circuit.The smart home system,which is composed of home gateway,coordinating nodes and terminal nodes,adopts the design of high-performance processor S5PV210,to reach data's exchanges between domestic internal communication network and external Internet.Both the coordinating node and the terminal node are designed by the CC2530 chips.The function of the coordinating node is to set up and manage the Zigbee communication network.The terminal node is mainly to collect internal environment information and control the running of household appliances.(3)The software design of the system.The smart home system is designed by the S5PV210 processor and the CC2530 chips.The main modules include the construction of embedded Web server,the design of CGI dynamic web page and HTML static web page,the transplantation of Linux system,as well as the programming of monitoring temperature,humidity,fire and gas leak.(4)The accomplishment of the system.Using the S5PV210 chip as the core processor of the home gateway,the CC2530 module is used as the coordination node and the terminal node to realize the function of the whole system.Therefore,the users can monitor residential environment by visiting the Web server,and the system will send alarm messages to users through GSM module and promptly deal with them when there are fire and gas leak.The results of the experiments show that the smart home system accomplishes the remote check on the internal residential environment,controls the household appliances,and sends message promptly when the house is in danger,which will meet the demand of modern home life.
