摘 要
    随着我国经济的飞速发展，城市人口日益增多，特别是改革开放以来，城市汽车量的不断增加。以往那种单层平面的停车场也越来越不能满足市场的需求。对多停车位、少占空间、使用造作简单、安全可靠的立体停车库的建设是解决目前寸土寸金的大城市内停车难的有效办法。
立体车库是一种多平面的空间停车库，通过可编程控制器PLC控制车位的空间位置变动，使车位能够实现空间停车的功能。升降横移立体车停车库利用托盘移位产生垂直通道，实现多层车位的升降来取车辆。
本文介绍了基于可编程控制器(PLC)的车库控制系统，简述了3层3列式7车位升降横移式立体停车库的工作原理、结构特点、并通过PLC软件设计及其优化，实现了立体车库的自动控制。整个系统由载车部分、传动系统、控制系统等组成。用PLC内的预置程序来控制整个系统的运行，用电机的正反转来控制车位的上下左右移动实现存取车的自动化。该系统又具有以下保护功能：急停、断电保护。

Abstract

With the rapid development of China's economy, city population increasing, especially since the reform and opening up, increasing the amount of car city. The parking lot that single plane is also more and more can not meet the market demands. Of parking, occupies less space, using the construction of artificial simple, safe and reliable stereo garage is to solve the big city Cuntucunjin parking difficult effective way to.Stereo garage is a multi plane parking space, controlled by a programmable controller PLC parking space position changes, which can realize the function of parking space and parking. Up-down and translation stereo car garage by shifting the tray to produce the vertical channel, realize lifting multilayer berth to take the vehicle.
Based on programmable controller (PLC) garage control system, this paper describes the the working principle and structural characteristics of 3 layer 3 - 7 parking spaces for up-down and translation stereo garage, and through the PLC software design and optimization, the realization of the automatic control of the stereo garage is introduced in this paper. The whole system consists of vehicle parts, transmission system, control system etc.. With the PLC within the preset program to control the operation of the entire system, with the motor to control the positive and negative parking spaces around the car to achieve the automatic access. The system has the following protection function: emergency stop, power off protection.
Key words: Stereo parking garage  PLC   Auto-Control
