摘　　要：本文研究的内容是对工作环境恶劣条件下的高压开关柜的温度进行检测与预警。对高温高压,强电磁干扰环境下的高压开关柜进行温度检测和预警是一件不宜之事,为实现温度的检测本文主要通过利用高压柜工作时母线排所辐射出的红外波段强度进行对能量的判断,使用红外传感器对能量信号进行采集,通过带屏蔽罩的放大滤波电路将信号传输给增强型STM32F103进行信号处理,经逻辑分析后预判此时的温度安全性,并做出相应的指示。The content of this paper is the detection and early warning of high voltage switch cabinet for poor working environment under the conditions of the temperature.On the high temperature and high pressure,high voltage switch cabinet under intense electromagnetic interference environment temperature detection and warning is an unfavorable things,in order to realize the detection of the temperature mainly by infrared band intensity using high voltage cabinet work of energy radiated by the judgment of the use of infrared sensor,thermopile to collect energy signal,through with shield cover amplifying and filtering circuit transmits signal to the enhanced STM32F103 signal processing, the logic analysis of pre judgment security after the temperature at this time,and make the corresponding indicator.
