摘　　要：提出了一种利用示温腊片测温原理和图像处理技术进行变电站高压触点温度在线监测的新方法,并基于该方法设计实现了一个能够实现无人值守的低成本触点温度在线监测告警系统。介绍了该系统的工作原理、组成、功能及其软、硬件设计中的几个关键问题。室内外实验表明,该系统运行可靠、效果良好,可以准确实现变电站高压触点温度的在线监测。By exploiting the operating principle of the temperature-indicating wax label and image processing technology, a novel method for remote on-line temperature detection of substation high-voltage contacts is put forward. A low cost and unmanned warning system based on the method is designed. The principle, configuration, function and some key questions about the hardware and software design of the system are discussed. In- and out-door experiments have proved that the warning system is practical and reliable.
