矿用低压配电柜温度监测系统设计
Design of Temperature Monitoring System for Low-voltage Distribution Cabinet for Mine
摘要
Abstract
Based on the analysis of radio frequency wireless communication technology, this paper introduces the temperature measuring principle of Pt100 temperature sensor, the formula of temperature and resistance conversion and the 433 MHz wireless module. PLC and 433 MHz wireless communication technology is used to design the temperature monitoring system of low-voltage distribution cabinet for mine to realize the temperature monitoring and fault alarm of low-voltage distribution cabinet for mine.关键词
