基于ZigBee技术的高压开关柜智能无线测温系统

摘要

A kind of real-time on-line wireless temperature measuring system was designed based on ZigBee technology. The system was used to monitor the temperature of high-voltage switchgear bus bars and connector lugs. Introduction was made to the software and hardware design of the measuring system and commonly used high-voltage switchgear temperature-measuring methods. The system used temperature sensor DS18B20 to collect temperature data and the temperature collector used ZigBee wireless networking technology to transmit the pro-cessed temperature data to data centralizer. The latter used field bus technology to make internet with the monitoring center computer, to have realized real-time, on-line monitoring. The system has had run two years in power supply company actually, the result proves that the system is safe and reliable.%　　基于ZigBee技术设计了一种实时在线无线测温系统，用于高压开关柜母线排、接线头的温度监测。介绍了测温系统的软硬件设计及常用的高压开关柜测温方式。系统由温度传感器DS18B20采集温度，温度采集器利用ZigBee无线组网技术将处理后的温度数据传输至数据集中器，后者利用现场总线技术与监控中心计算机互联，实现了实时在线监测。该系统已在供电公司实际运行两年，结果证明运行安全可靠。
