摘　　要：针对供电系统某些高压场合的温度不宜采用有线检测的问题,应用QRF-0400无线收发模块和PIC16F648A单片机,开发了一种基于ZigBee技术的无线温度传感器网络系统,具有节点功耗低、可靠性强、传输速率快的特点。阐述了无线传感器网络节点的硬件电路和工作原理,详细分析了节点的传输控制和睡眠唤醒节电模式的原理,给出采用多个节点组成星型网络监控温度的实施方案。还介绍了采用DELPHI语言开发的网络管理软件。研制的测温系统已用于电厂变电站的高压开关柜中。In order to solve the problem of thermometric detection can not be made by cable on some high-voltage power supply occasion, a wireless temperature sensor network system was developed based on the ZigBee technology through the application of wireless module QRF-0400 and control model PIC16F648A ,which has the properties of low power dissipation, high reliability and fast transmission rate. The hardware circuit and operating principle of the wireless sensor network node was illustrated, the principle of transmission control nodes and power-saving sleep mode was discussed in detail, and the implementation strategy which monitors and controls temperature by star network composed by multiple nodes was put forward. The network management software developed by DELPHI language was also introduced. The thermometric system has been applied in the high voltage switchboard in power plant substation.
