摘 要
本文介绍了基于可编程控制器(PLC)和Profibus总线的车库控制系统，简述了三层三列式七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。整个系统由钢结构部分、载车板部分、传动系统、控制系统、安全防护措施等组成。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，电机的转速和正反转则由变频器来控制，存车则由条码打印机来打出凭条，取车则把该凭条用条码扫描器扫进PC机，在通过Profibus总线传到PLC中去，实现存取车的自动化。该系统分为三个工作过程：自动运行、手动运行和停止运行，可用转换开关来控制。又具有以下保护功能：急停、断电保持、超长提示和离车保护。

Abstract
This article introduced based on programmable controller (PLC) and the Profibus main line''s garage control system, summarized three three row type seven berth to rise and fall moves to the type three-dimensional to stop the garage horizontally the principle of work, the unique feature, and through the PLC software design and the optimization, has realized the three-dimensional garage automatic control. The overall system by the steel structure part, carries the template part, the transmission system, the control system, the safety protection measure and so on to be composed. Controls overall system''s movement with the PLC in pre-placed procedure, transfers with electrical machinery''s pro and con controls berth''s about to move, electrical machinery''s rotational speed and is reversing controls by the frequency changer, parking splits out the certificate by the bar code printer, takes Che Ze to sweep into this certificate with the bar code scanner PC machine, in passes to PLC through the Profibus main line, realizes deposits and withdraws vehicle''s automation. This system divides into three work processes: The automatic movement, the manual movement and the stop movement, the available change-over switch controls. Also has the following protection function: Stops, the power failure maintains anxiously, the ultra long prompt and leaves the vehicle protection.

前 言
自动化停车库是机电合一的大型复杂产品,机械部分相当于人的躯体,电器部分相当于人的神经。机与电的高度合一,使自动化停车库成了现代科学技术的综和产品。
随着汽车的急增致使城市停车难问题不断恶化，而作为解决城市静态交通的有效措施——向空间、向高层发展的自动化立体停车设备，以其占地面积少、停车率高、布置灵活、高效低耗、性价比高、安全可靠等优点，越来越受到人们的青睐。目前市面上常见的机械式立体停车库有：升降横移类、垂直循环类、多层循环类、水平循环类、平面移动类、巷道堆垛类、垂直升降类和简易升降类等8种，其中升降横移类以其结构简单、操作方便、安全可靠、造价低等优点，在国内车库市场占有绝对优势的市场份额。
