基于西门子PLC电梯群控系统设计

西门子PLC在电梯群控系统中的应用

摘要

本文介绍了PLC控制的四层电梯模型的构成、主要功能、PLC的I/O接口分配、PLC 的编程方法及对电梯系统的程序设计等。通过对电梯控制系统的程序设计，实现了电梯的开关门控制以及在电梯运行方式下电梯的呼叫显示、上下行、起动、延时关门、平层、停靠开门、信号排队、顺向截梯和报警等控制功能。通过对软件程序的编译、硬件的连接以及电梯模型与PLC控制系统的联调，使得控制系统在电梯模型运行过程中直观的体现出来，实现了对电梯功能的控制。

本次设计主要将可编程序控制器（PLC）和计算机应用到电梯的控制系统中去，以两台四层电梯为例来完成电梯PLC群控制系统的总体设计方案、组成及模块化程序设计。

本课题的主要实现的功能：全集选控制、保持开门时间的自动控制、本层厅外开门、全自动状态下门开到位后会立即关门、开门按钮开门、换站停靠、错误指令取消、接停靠、待梯时轿内照明和风扇自动断电、层楼显示字符设置、显示器、火灾紧急返回运行、超载保护、门缝防夹保护、双刹车保护。

Application of Siemens PLC in the Elevator Group Control system

abstract

This paper introduces the PLC-controlled model of a five-story elevator，include it’s composition, main function, the I/O interface distribution of the PLC, the PLC’s programming methods and procedures design of the elevator system. With procedures design of the elevator control system can achieve the elevator door’s opening and closing control, and the elevater’s indication under the call, moving from top to bottom, starting-up, delay closed, Ping layer, opening the door, making signals in the queue, close to the escalator and alarming control under the mode of the elevator’s operation mode. Through the process of compiling software, hardware connection and the conjunction of elevator model and the PLC control system, which makes the elevator control system model intuitive reflected in the course of operation and realized the elevater’s functional control.

The design mainly PLC (PLC) and computer application to the elevator control system, and to four-story elevator as an example to complete a single lift PLC program control system design, composition and modular program design .

The main task of the transformation of the subject design : The Complete Works of select control, automatic control to maintain the opening hours of the hall floor to open the door, the automatic state under the door opened place immediately closed the door open button to open the door, the other stops here, the faulting instruction to cancel, then stop, when the car in question staircase lightingand fan automatic power-off, the floors character sets, monitors, fire

emergency return to operation, overload protection,door anti-pinch protection,Dual brake protection.
