1、电梯运行控制系统的PLC设计崔莉摘要随着社会经济的快速发展，全国各地高层建筑不断涌现，作为高楼的垂直交通工具——电梯，其需求量日益增长。各种类型规格繁多的电梯已在高楼内投入运行。为了确保电梯正常运行、安全使用，必须要了解电梯、管理电梯、维护好电梯。本文介绍了利用三菱FX2N系列可编程控制器（PLC）在五层电梯控制系统中的应用，介绍了电梯的发展概况，PLC的应用领域，电梯的分类及主要构件，该设计所要实现的控制功能和要求，主要讲了电梯的控制系统。该设计以PLC为主控制器，采用交流异步电动机调速系统和集选控制方式，利用三菱FX2N系列软件编程，编辑了开关门环节梯形图
2、、厅外召唤梯形图、厢内按钮梯形图、定向环节梯形图、停层信号梯形图、启动稳速成减速制动环节梯形图，实现了五层电梯自动响应层楼请求服务的召唤信号，自动响应轿厢请求服务的指令信号，自动完成轿厢层楼位置的显示，自动显示电梯的运行方向等基本功能和控制要求。关键词电梯,运行控制,系统设计,PLCIABSTRACTAlongwiththesocialeconomyfastdevelopment,eachplacehigh-riseconstructionemergesunceasingly,tookthetallbuildingtheverticaltransportati
