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。

ABSTRACT
PLC (programmable controller) takes one industrial control microcomputer, it is convenient by its programming, simplicity of operator its merits and so on high controllability, obtained the widespread application particularly in the industrial production process. It applies the large scale integrated circuit, the miniature machine technology and the mechanics of communication development achievement, formed gradually had many kinds of merits and miniature, medium, large-scale, the ultra-large type and so on each kind of specification's serial products, applied to monitors between computer's many control domain from the black-white control system. Along with society's unceasing development, the building is getting higher and higher, but the elevator became the high-level building to the equipment. The elevator from the handle switch operation elevator, the push-button control elevator develops to present's group control elevator, has made the indelible contribution for the high-level transportation. PLC mainly manifests in the elevator cuing control's application in its logical switch control function. Because PLC has the logic operation, counting and fixed time as well as data feeds output function. In the elevator rises and falls in the process, each logical switch control and the PLC very good union, very good have realized to the fluctuation the control.
