Now the elevator control system mainly has three ways: the relay control system, PLC control system, microcomputer control system. PLC control system with high luck reliability, maintenance convenience, strong anti-interference, design and debugging cycle short advantages, people pay more and more attention, has become the elevator control system in the use of most of the control method.In this paper, the structure of the elevator and on the basis of structure and working principle of the programmable controller, for the six store elevator, using Siemens S7-200 programmable controller, the design of elevator control system, including car instruction and the hall call information for the registration and eliminate, elevator layer and set to, the elevator door switch operation, elevator control, elevator to control layer, the car and each layer of call instruction records, the elevator running direction and layer selection control, elevator up and down and automatic opening and closing the door, elevator refers to the layer control, and other functions.Key words: six layer elevator; control system; programmable controller;- 1 -目目 录录摘 要.1Abstract.1绪论.11.1 电梯的概述.11.1.1 电梯的分类.11.1.2 电梯的组成.21.1.3 电梯的工作原理.21.1.4 电梯的国内外发展状况.31.2 PLC 控制电梯的优势.51.3 电梯的发展趋势.61.4 一般控制要求.61.5 课题研究内容.62 硬件系统的组成.82.1 可编程控制器简介.82.1.1 PLC 的结构及各部分的作用.82.1.2 PLC 的工作原理.102.1.3 PLC 的程序编制.102.1.4 PLC 的输出方式.142.2 PLC 型号选择.152.3 行程开关的概述.172.3.1 行程开关的分类.172.3.2 行程开关的选择.192.4 系统安全设计.202.5 硬件外部接线图.223 软件设计.23- 2 -3
