Design of Temperature Measuring System Based Wireless Sensor Network

基于无线传感器网络的温度采集系统主要包括上位机、以CC1110为核心的汇聚节点和传感器节点。设计了汇聚节点和传感器节点的硬件电路和软件,采用DSDV(Destination-SequencedDistance-Vector)路由协议建立网络拓扑结构,实现了温度数据的获取、无线传输和处理。测试结果表明,系统工作稳定,具有低功耗、低成本等优点。

This paper presents a temperature measuring system based wireless sensor network, which consist of upper monitor control PC, sink node and sensor node with CC1110 as the core. The hardware circuit and software of sink node and sensor node were designed. The maintenance of network topology was imple-mented by destination-sequenced distance-vector routing protocol. The system can measure, transmit by wire-less, and process real-time temperature data. The result shows that the system works reliably and has low pow-er consumption and cost.
