Abstract: In allusion to problems such as maintenance difficulty and data monitoring incompleteness of distributed high voltage towers, a rotary infrared scanning status inspection system for high voltage towers is developed. The system consists of the temperature measurement node, data server, and Internet of Things (IoT) platform on the PC terminal. The STM32 is taken as the microprocessor to control the cloud platform of the double steering engine for angle rotation, so as to realize temperature measurement of electrical contacts by the infrared thermometer. The SIM900 module is used to transmit temperature data to the data server. The numerical feedback angle positioning algorithm is used to perform secondary measurement of abnormal electrical contacts. The working conditions of all high voltage towers in a certain area can be viewed from of IoT platform on the PC terminal, which largely solves the monitoring problem of high voltage towers.

Keywords: STM32; high voltage tower; infrared temperature measurement; numerical feedback angle positioning; IoT platform; secondary measurement

隨着全国范围内用电的需求日益增大,电力设备越来越多,这给电力设备的维护监测造成很大的困难。高压电塔是国家电网的重要组成部分,且分布极为广泛,这就产生了高压电塔维护的问题。现有的人工巡检是电网巡检的主要方式,采用原始的测量、记录的模式对高压电塔进行逐一排查,耗费巨大的人力物力,并且也存在遗漏、检错、排查周期长、偏远地区巡检难等问题。

针对上述问题,本文利用物联网技术中的感知技术、网络技术、应用技术与红外测温技术结合,设计出一套自旋转式红外扫描的高压电塔状态巡检系统。这套系统与传统人工巡检相比,突破了传统的测量局限性,测温耗时更少、巡检周期更短、管理效率更高、数据更新更及时,为大范围内高压电塔的长期维护提供了一种很好的解决方案。……
