基于PLC的立体停车库控制系统设计与仿真(含梯形图)(论文15000字)
摘要
随着我国经济的快速发展和人们生活水平的日益提高，特别是改革开放以来，城市汽车数量的不多增加，以往那种单层平面的停车场已经满足不了市场的需求。汽车作为一种重要的交通工具与人们的日常生活密不可分，成为城市发展的一种标志。
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，进而实现立体停车的功能。升降横移式立体停车库利用传送装置使载车板移位产生垂直通道和横向通道，实现多层车位的升降进行存取车辆。在对立体停车库的控制上，主要有手动控制，微机计算机控制和PLC控制三种控制方式。相对于其它两种而言，PLC控制具有明显的优越性，它使用时间长，自动化水平高，安全性能好，操作简单，它是最可靠的方式。
本文主要是基于PLC的车库控制系统，简述了2层3列式5车位的升降横移式立体停车库的设计和工作原理。立体停车库主要由机械系统、传动系统、控制系统、载车板部分和安全保护等组成。传动系统主要是通过三相异步电机的正反转来控制载车板的上下左右移动，以此实现存取车的自动化。
关键词：立体停车库 控制系统 PLC
Abstract
With the rapid development of economy of our country, and people's living standard is increasing day by day, especially since the reform and opening up to the outside world, the number of automobiles in the city have increased, formerly that kind of single layer plane parking lot has to meet the needs of the market. As an important vehicle, the vehicle is closely related with people's daily life, and it becomes a sign of city development..
Stereo garage is a multi planar space parking garage by programmable logic controller (PLC) control parking space position changes, so as to realize the function of parking. The up-down and translation stereo garage the conveyor that carries the template shift to produce a vertical channel and a horizontal channel, realize the multilayer parking lifting vehicle access. In the control of the parking lot, there are three control modes: manual control, computer control and PLC control.. Compared with the other two, the PLC control has obvious advantages, it is used for a long time, high level of automation, good safety performance, simple operation, it is the most reliable, use and spirit with the.
In this paper, the design and working principle of the control system based on PLC in the garage, and expounds the 2 layer 3 - 5 parking spaces in the up-down and translation stereo garage. Parking is mainly composed of a mechanical system, transmission system, control system, car carrying part and safety protection etc.. Transmission system is mainly through the positive and the negative rotation of the three-phase asynchronous motor to control load floors down and move around, so as to realize the automation of vehicle access.
Key words: parking equipment,control system, PLC
