多层建筑小型电梯控制系统设计
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。

Small Elevator Control System Design For Multi-story Building
Abstract
Elevator control system has three control modes: relay control system, PLC control systems, computer control system. PLC control system, high reliability, easy maintenance, strong anti-jamming design and debug cycle is shorter, etc., much of people's attention, has become in the elevator control system most frequently used control methods.
   This paper described the structure and working principle of the structure and the programmable controller of the elevator on the basis of, for the four-story elevator, use the Siemens S7-200 programmable controller, the design of the elevator control system, including the car in order and hall call registration and cancellation, of the signal layer selection and orientation of the elevator, the elevator door switch to run the elevator up and down the line control part of one layer of the elevator control, the instruction records the car with layers of call ladder, elevator running direction and choose layer control, lift up and down the line, and automatic door switch elevator refers to the layer control and other functions.
Keywords: four-story elevator control system programmable controller
