1、摘要可编程控制器简称PC（英文全称：ProgrammableController），它经历了可编程序矩阵控制器PMC、可编程序顺序控制器PSC、可编程序逻辑控制器PLC（英文全称：ProgrammableLogicController）和可编程序控制器PC几个不同时期。为与个人计算机（PC）相区别，现在仍然沿用可编程逻辑控制器这个老名字。PLC是一种专门为在工业环境下应用而设计的数字运算操作的电子装置。它采用可以编制程序的存储器，用来在其内部存储执行逻辑运算、顺序运算、计时、计数和算术运算等操作的指令，并能通过数字式或模拟式的输入和输出，控制各种类型的机械

2、或生产过程。PLC及其有关的外围设备都应该按易于与工业控制系统形成一个整体，易于扩展其功能的原则而设计。随着经济的发展，现代城市中的高层建筑日益增多，电梯成为人们日常生活必不可少的代步工具。而电梯性能的好坏，除了电机等硬件以外，电梯控制系统是其核心因素。PLC因其简单易用、可靠性高、维修养护方便和抗干扰能力强等优点，在电梯控制领域应用极为广泛。本文以三菱FX2N系列PLC为例，以五层电梯为设计对象，分别从电梯控制系统的构成及工作原理，系统PLC配置方案，PLC软件设计，PLC软件的调试仿真和电梯硬件选取等方面，详细的阐述了PLC在电梯控制系统中的应用，形成

3、了以PLC为控制系统的完整的电梯模型，使电梯在更精确、更可靠、更快速的控制平台上运行。关键词：编程；电子装置；电梯控制；PLC；发展目录摘要··································································Ⅰ第1章电梯的简介···················································11.1电梯的起源与发展················································11.2电梯的分类················
