The Low-power Distributed Temperature Detection System Based On Zigbee Research

With electronic technology, the sensor technology and communication technology are development in recent years. The modern sense is rising greatly. And in the military and civil aspects; wireless sensor network has been widely used. As ZigBee wireless sensor network with low power consumption, low rate and low cost, wireless sensor network widely used in industrial control, modern agriculture control, digital home, the intelligent building monitoring, the village water and electricity meter reading, etc.This paper introduced the ZigBee, characteristic of wireless sensor network, and analyzed the key points of the ZigBee low power consumption and low rate in the wireless application in the field of wireless sensor advantage.ZigBee wireless sensor network is mainly used in short-range wireless system. According to the actual network applications, the system use adaptive weighted fusion algorithm and neural netword fusion algorithm to make the correcting data more accurate and credible.The system based on the CC2430+C51to develop network coordination, routers, and end nodes. And the system collected temperature data by using digital temperature sensor18B20,Through researching the IEEE802.15.4standard agreement and ZigBee standards, the software is completed in IAR730B environment. The programming has realized networking of ZigBee network coordinator, data processing program, router joining the network and terminal equipment joining the network and the program of collecting temperature. In the PC, we use VB software to design detection software by monitoring nodes.
