DS1820数字温度传感器rn在机械设备温度监控中的应用

摘要

DS1820是DALLAS公司近年推出的新型数字温度传感器，在某空压机监控系统中，我们用AT89C2051单片机和18片DS1820构成一温度采集板，经RS－232－C串口连至监控系统的工控计算机。将DS1820数字温度传感器贴装于机械设备和管道表面进行温度测量，并由软件对所测点的温度进行补偿。%This paper introduces a temperature－Collecting board ,composed of AT89C2051 MCU and 18 DS1820 digital temperature sensors. It is linked to an industrial control computer of monitoring and controlling system of air compressor by RS－232－C series port. DS1820 is fixed on the surface of machinery and pipes to measure temperature, temperature is compensated by software.
