四层电梯的PL控制设2.doc

四层电梯的PLC控制设计 摘要 主要分为机械系统与控制系统两大部份。目前电梯控制系统主要有三种控制方式：继电器控制系统、PLC控制系统、微机控制系统。而PLC控制系统由于运行可靠性高，使用维修方便，抗干扰性强,设计和调试周期较短等优点，倍受人们重视等优点，已成为目前在电梯控制系统中使用最多的控制方式，目前也广泛用于传统继电器控制系统的技术改造.本次设计过程中得到了韩浩老师和许多同学的大力支持和帮助，在此一并表示感谢。由于本人水平有限，本设计中难免有不当和错误之处，恳请各位老师或是各界人士批评指正。 关键词: 电梯 控制系统 电梯系统运行和调试随着科学技术的发展、近年来，我国的电梯生产技术得到了迅速发展．电梯 Abstract Along with sciences and technologys development, the recent years, our countrys elevator production technology obtained the rapidly expand. The elevator mainly divides into the mechanical system and the control system two major parts automatic control theory and microelectronic technologys development。At present the lift control system mainly has three control modes: Following electric circus control system 。 PLC control system, microcomputer control system. But PLC control system, because moves the reliability to be high, the use service is convenient, anti-jamming, the design and the debugging cycle is short and so on merits, time is taken seriously the people and so on merits, have become present use most control modes in the lift control system, at present also widely use in the tradition black-white control systems technological transformations. In this design process obtained this institutes motherland to construct (associate professor) and many colleagues’ supports vigorously and helps, one and expressed thanks in this. Because myself level is limited, in this design has improper and place of unavoidably the mistake, requests earnestly fellow teachers perhaps the people from all walks of life criticizes points out mistakes. Key word: lifts control system elevator systems operation and debugs。 目录 第一章 前言 2 第二章 绪论 3 一、设计任务 3 二、设计目的要求 3 三、设计说明 3 四、电梯运动的控制要求 4 第三章 电梯的主要机械部件.......................6 一、电梯的分类..................................................................................6 第四章 可编程控制器硬件、软件的概述及PLC编程设计 7 一、可编程控制器的概述 7 二、SIMATIC STEP 7编程软件的介绍 8 三、PLC型号的选择 8 四、地址分配表 10 五、PLC程序设计思路及程序 11 1.设计思路 11 2.程序图 12 3.对电梯控制系统的描述 17 第五章 结束语 18
