氢气冷却干燥机多点温度采集系统设计与实现

Design and realization of computer multipoint temperature collection system of hydrogen cooling drier

本文设计了一种实用新型计算机多点温度采集系统,采用Cu50传感器作温度传感器,ICL7109作模数转换器,单片机采用AT89C51或AT89C52和AT89C2051。测量误差符合系统所规定的要求。

This paper proposes a new practical computer based multipoint temperature collecting system. The system uses A Cu50 as temperature sensor, ICL 7109 as Mod-Digit switcher, microchip AT89C51 or AT89C52 and AT89C2051 as down termination. The measure error is within the prescribed toleration.
