摘要 PAGE 44 PAGE 45 基于PLC的电梯控制系统设计 摘要 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。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，已成为目前在电梯控制系统中使用最多的控制方式。 本文在阐述电梯的结构和可编程控制器的结构和工作原理的基础上，针对4层电梯，使用西门子S7-200可编程控制器，设计了电梯的控制系统，包括轿内指令和厅外召唤信号的登记与消除、电梯的选层和定向、电梯的开关门运行、电梯上下行控制、电梯的指层控制等部分，实现了轿内与各层呼梯指令的记录、电梯运行方向和选层的控制，电梯上下行和自动开关门、电梯的指层控制等功能。同时也使用了组态王6.53完成上位机对PLC控制电梯的仿真。 关键词：四层电梯 控制系统 可编程控制器 组态王 Abstract Abstract PLC-based elevator control system design Abstract At present the elevator control system mainly has three control modes: Following electric circuit control system, PLC (Programmable Logic Controller) control system, microcomputer control system. 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 elevator control system. This article elaborated the elevator structure，the structure and the working principle of the programmable logic controller．Aim at the elevator of four floors，the writer design this elevator control system by the use of Siemens S7-200 programmable logic controller．The writer design the elevator control parts, such as, the part of register and cancel the instructions from the cabin, the part of register and cancel the instructions from the station hall, the part of choose station and direction, the part of door movement，the part of elevator operation，the part of shown layer ，and so on．These parts achieve the functions：registering the instructions from the cabin and the station hall, choosing the direction and the station of elevator，elevator go up or down and door automatically，fingering out the location of the cabin, and other functions.Also use kingview 6.53 complete pc to plc control elevator simulation.
