1、 PLCPLC 三层楼电梯系统设计与调试三层楼电梯系统设计与调试 摘要：摘要： PLC（可编程控制器）作为一种工业控制微型计算机，它以其编程方便、操作简单尤其是它的高可 控性等优点，在工业生产过程中得到了广泛的应用。它应用大规模集成电路，微型机技术和通讯技 术的发展成果，逐步形成了具有多种优点和微型，中型，大型，超大型等各种规格的系列产品，应 用于从继电器控制系统到监控计算机之间的许多控制领域。随着社会的不断发展，楼房越来越高， 而电梯成为了高层楼房的必须设备。电梯从手柄开关操纵电梯、按钮控制电梯发展到了现在的群控 电梯，为高层运输做出了不可磨灭的贡献。PLC 在电梯升降控制上的应用主要体现在
2、它的逻辑开关 控制功能。由于 PLC 具有逻辑运算，计数和定时以及数据输入输出的功能。在电梯升降过程中，各 种逻辑开关控制与 PLC 很好的结合，很好的实现了对的控制。 本文主要讨论研究利用欧姆龙 CPM1A PLC 对电梯的升降进行控制，形成电梯控制系统。 关键词：关键词：PLC 电梯控制电梯控制 欧姆龙欧姆龙 升降升降 ABSTRACT： PLC (programmable controller) takes one industrial control microcomputer, it is convenient by its programming, simplicity of op
