1、 1 PLC 在电梯控制系统中的应用 摘 要 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 (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靠性等优点,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。 PLC 在电梯升降控制上的应用主要体现在它的逻辑开关控制功能。
2、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,很好的实现了对升降的控 制。 本文主要讨论研究利用日本 OMRON 公司的 C 系列 P 型机对电梯的升降 进行控制,形成电梯控制系统。 关键词:PLC,工业控制,电梯升降控制,OMRON 2 THE APPLICATION OF PLC IN THE CONTROL SYSTEM OF ELEVATOR ABSTRACT As the city continues to develop, more and more high buildings are built, s
