苏州市职业大学机电工程学院毕业设计(论文) I 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。本文主要讨论研究利用三菱 PLC 对电梯的升降进行控制,形成电梯控制系统。关键词: PLC ;电梯控制;升降苏州市职业大学机电工程学院毕业设计(论文) II PLC Control Elevator Design Department ABSTRACT PLC (programmable controller) took one industry control puter, itby its programming convenient, operation simple in particular its merits and soon high controllability, obtained the widespread application in the industrial production applies the large scale integrated circuit, the miniature machine technology and munication technology development achievement, formed gradually had many kinds of merits and miniature, medium, large-scale, the ultra-large type and soon each kind of specification series product, applied in to monitors between puter from the black-white control system many control with society's unceasing development, the building is more and more high, but the elevator became the high-level building to have the elevator from the handle switch operation elevator, the push-button control elevator develops to the present group control elevator, has made the indelible contribution for the high-level rises and falls in the control in the elevator the application mainly to manifest in its logical switch control PLC has the logic operation, counting and fixed time as well as data feeds output and falls in the process in the elevator, each logical switch control and PLC very good union, very good realization to control. The this article main discussion studies using Mitsubishi PLC carries on the control to the elevator fluctuation, forms the elevator control system. KEY WORDS : PLC , Eleva
