摘要
基于电力系统中对高压触点温度测量的实际需求,研发了一套高压触点温度无线监测系统。该系统由无线温度传感器节点网络、无线遥测网络和监测主机三个部分组成。无线温度传感器节点采用DS18B20测量温度,CC2430单片机读取温度数据并实现ZigBee无线通信技术的灵活组网。无线遥测网络是由无线温度监测仪经CAN工业总线互联而成。无线温度监测仪作为ZigBee子网内的主节点,负责接收各节点温度数据,并向监测主机转发。监测主机完成对所有节点温度的显示、判断、存储等工作。系统已在现场投入试运行,性能良好,为电力系统的安全运行提供了有力支持。
According to requirements of measuring high voltage contacts＇ temperature in power system, a set of high voltage contacts＇ temperature wireless monitoring system is developed. The system consists of wireless temperature sensor nodes network, wireless telemetering network, and monitoring host computer. The wireless temperature sensor nodes are measured by DS18B20. CC2430 single-chip reads temperature data and the flexible network is realized by ZigBee wireless communication technology. Wireless telemetering network is interconnected by wireless temperature monitor through CAN bus. And the wireless temperature monitor, as the main node of ZigBee suhnet, is responsible for receiving nodes＇ temperature data and transferring data to host monitor computer. Host monitor computer completes the display, estimation, and store of all nodes＇ temperature. The system is put into operation on site. The performance of the system is good and provides a strong support for the safe operation of the power system.
