Research On Wireless Temperature Sensor Network System Based On Zigbee Technique

The WSN(wireless sensor network, WSN) is wireless network of the oriented actual taskthat is composed of nodes and deployed in the monitoring area. The node is compose of sixmajor functional modules by power, sensors, microprocessors, communication module andembedded software system. It is wireless network between each nodes that is formed amulti-hop and self-organizing WLAN(Wireless Local Area Network，WLAN)through thecorresponding transport protocol, and then Data-information is sent to data processing controlcenter by the optimizing process along a certain path. This kind of sensor network is a blendof knowledge of multiple subjects by microelectronics technology, modern network, wirelesscommunication network and BScComputing technology etc.This article which is combined with WSN put forward the design scheme of “WirelessTemperature Sensor Network System based on ZigBee Technique”. This scheme is built onthe basic of fundamental theory of WSN, and designed from hardware and software throughresearching on the establishment of ZigBee network and the method of information collection.In the aspect of software, it is mainly designed by the microprocessor module, dataacquisition module, wireless module and some peripheral circuit; In the aspect of hardware, itis designed by the nodes of wireless temperature sensor network based on Z-Stack, includingjoining node, allocating network address assignment, data collection etc. In the indoorenvironment of Institute of Micro-nano Electronic, Chang’an, the project achieved the resultof building a star network in10meter，and designed computer software.It is fully proved that the system can realize wireless transfer of temperature data, andvalidated the characteristics of “Wireless Temperature Sensor Network System based onZigBee Technique”, such as the reliability of temperature data wireless transmission, thenetwork construction is simple and efficient and low power consumption.
