| The wireless network (WSN) is made up for a great deal of sensor nodes through wireless communication technology . WSN can realize data collection, precessing, amalgamation, transmission and application. These application have commonly no use of great bandwidth, but need low power consume. Wireless sensor network is very different from traditional network, The former focus on data, and the later focus on Transmission Of Data. Sensor network technology was firstly used in military systems. But now, it has been used in almost all of the fields with the development of sensor network technology. At the same time, it more and more requires lower cost, larger battery life, more reliable and robust communications, so, ZigBee protocol emerge as the times require.ZigBee technology is a developed short distance wireless two-way communication technology. This technology has the merits of agreement simply, the power loss low, the network ability strong, the network capacity big, when extended short, safe, reliable and the cost is low and so on. It also had the functions of way choice, automatically links the network and self-Recovery. ZigBee wireless sensor network combines sensor technology, communication technology and computer technology together. It has the ability of collecting, transferring and processing data.This article maily designed the WSN nodes, adopt ZigBee setup network protocol, descibed the location process, designed a router protocl, which combine manage software, can accomplish the data disposaland carry. This system have the coordinator, router nodes and reduce function device, this nodes can found self-organise network. It debased the complexity of network collection , and adjust the network topology network frame dynamicly. This system applied to the shandong science&technolgy museum in 2007. If this system be improved on a bit it can applianced groundes such as: carport, supermarket, colliery, hospital or fire protection. |
