内容简介：

摘 要 随着微电子技术和计算机技术的迅速发展， PLC（即可编程控制器）在工业控制领域内得到十分广泛地应用。 本文主要讲述了 PLC 在货运电梯中的应用。利用 PLC 的编程方法，在分析、处理随机信号逻辑关系的基础上 ， 写 出了具体的主要硬件电路、电梯的控制梯形图及指令表，并给出了系统组成框图和程序流程图。本论文主要设计了电梯的上行，下行以及检修，和楼层显示等，在论文中有详细的介绍。 关键字 ： 可编程控制器 电梯 梯形图 ntsAbstract According to quick development of microelectronics and computer technology PLC (adjusting device that piece together program soon) industry area control that is very wide inside gets and applies .Body did PLC goods transport elevator inside application in just liquor mainly. Use method that piece together PLC program, and analysis, handle footing of random signal logic relation on upside, appear because begin to use specific important hardware electric circuit, elevators control trapezoid helm and command, and offers system and makes up quadrilateral picture and program schematic diagram. Two papers mainly elevators going up, and convey checking repair mainly and, demonstrate with each floor, and there is detailed dispersal within paper. Design thought mainly introducing of this design within paper, designing a tool and elevators basic function etc. Keyword : Adjusting device
