PLC在实验室中央空调系统控制中的应用

PLC Application in Laboratory Central Air-Condition System Control

本文通过对PLC为现场控制工作站的中央空调系统与传统的继电器系统的比较,介绍了PLC为现场控制工作站的实验室中央空调系统的优点、组成及工作过程,对系统的硬件设计及PLC软件设计方法进行了分析与说明,并给出了部分程序。

By comparison of the central air-condition system that PLC stands for the control work on-the-spot and the relay system of tradition, this paper introduces the advantage, form and work course of the laboratory central air-condition system that PLC stands for the control work on-the-spot. It analyzes and explains the method of PLC software and hardware design of system, and give partial program.
