| In recent years, with the development of science and technology, demand for family living circumstance with safety, comfort and convenience is increasing. The concept of smart home originated on American is increasingly recognized. Many units and individuals join the research of smart home and product development, and put forward many kinds of solutions. Although the services of the smart home become ever more diverse, many systems with complicated structure, high cost and mostly use communication cables to set up home network and lack of uniform standards, so that many of them fail to widespread use.Against the shortcomings of the smart home system, according the tendency, by analyzing all kinds of home networking technology, put forward a kind of household monitoring system based on ZigBee. The system combines various technologies including ZigBee wireless networking, GPRS and internet remote access technology, which adopt ZigBee to set up home network, family PC as the server, realize long-distance monitor by internet, utilize GPRS to realize SMS alarm. In this paper, the GSM/GPRS module, ZigBee communication module, sensor detect circuit and equipment control circuit are designed, and developed the software driver program, adopt LabVIEW to develop human interface of smart home monitoring system. In order to improve the real-time and reliability in data transmission on home network, though analyze the Cluster-Tree routing algorithm, combine with AODVjr routing algorithm idea, a kind of improved ZigBee routing algorithm is given. At last, construct a system test platform, test the performance of ZigBee module and system’s function.The smart home monitoring system realize the basic security and control part of the electrical equipment, which can perform remote monitoring and SMS alarm. System has characters of low cost, stable data transmission, network node without wiring easy layout, human interface is concise and easy to operate etc., which has referential and practical value. |
