基于PLC的电梯电气控制系统设计

Design of Elevator Electrical Control System Based on PLC

电梯作为重要的垂直运输工具之一,广泛应用于高层建筑及一些特殊场合,对于提高人们生活质量有着十分重要的意义。可编程逻辑控制器(Programmable Logic Controller,PLC)作为一种高度融合了自动控制技术、计算机技术和通信技术的先进科技产品,已经广泛应用于工业领域,其采用模块化设计方法进行控制,通过对现场信息进行采集并处理,实现自动控制功能。基于此,采用德国西门子S7-200系列的CPU226作为核心控制器,实现对电梯的控制。

As one of the important means of transport,widely used in high-rise buildings and some special occasions,to improve people's quality of life has a very important significance.Programmable Logic controller(PLC)as a highly integrated automatic control technology,computer technology and communication technology of advanced scientific and technological products,has been widely used in various industrial fields,using modular design method for control,through the field information collection and processing,to achieve automatic control function.This design uses the German Siemens S7-200 series CPU226 as the core controller,achieve the control of the five-floor elevator.
