摘要
随着我国国民经济的不断发展及城市现代化要求，汽车在我国越来越普及，而这将导致大中等城市“停车难”问题日益凸显。在现有的土地资源条件下，多层的机械式立体停车库可以很好的提高现有土地资源的利用率，充分发挥土地资源的空间优势，使得汽车的存放数量得以优化，从而快速有效地解决大中等城市“停车难”问题。本论文以一个三层三行三列二十一车位的升降横移式自动化立体停车库为主要研究对象，在深入分析了立体停车库运行原理的基础上，采用可编程控制器（PLC）为主要控制单元对该立体停车库控制系统进行设计。论文研究的主要内容为：
1、 针对机械式立体停车库类型、国内外发展现状以及我国行业发展中存在的问题等进行研究。
2、 选定以三层三行三列6+6+9结构二十一车位升降横移式立体停车库为研究模型，研究该立体停车库的总体结构设计及车库运行原理等。
3、 对升降横移式立体停车库的硬件系统进行设计。内容包括：主回路设计，手动控制系统设计，PLC外围硬件设计，绘制了车库主电路图，手动控制电路图和PLC外围电路接线图等。
4、 对升降横移式立体停车库的软件系统进行设计。内容包括：PLC总体介绍，PLC编程语言的选择，设计了程序主框架流程图，各基本功能程序流程图，按要求编写了梯形图程序等。
5、 采用S7-200仿真软件对升降横移式立体停车库进行在线仿真与调试。
本论文重点对升降横移式立体停车库总体结构和控制系统的硬件、软件系统进行设计。设计过程采用模块化设计思路，结构灵活，通过对PLC软件系统设计及优化，使得本立体停车库具备智能化控制的功能，实现了立体停车库停车位能够安全、稳定、准确、快速的移动至人车交接处进行存取车操作。该立体停车库充分发挥土地资源的空间优势，大大提升了土地资源的空间利用率，是应对大中等城市停车难问题的有效解决方案。

Abstract
With the continuous development of China's national economy and the requirements for urban modernization, automobiles are becoming more and more popular in China,
and this will lead to the growing problem of “difficult parking” in large and medium-sized cities. Under the current conditions of land resources, multi-layered mechanical parking garages can greatly improve the utilization of existing land resources, give full play to the spatial advantages of land resources, and optimize the storage of automobiles, thus quickly and effectively. Solve the problem of "difficult parking" in large and medium-sized cities. In this paper, a three-tiered, three-row, three-column, twenty-one parking spaces are used as the main object of study. After deeply analyzing the operation principle of the three-dimensional parking garage, a programmable controller (PLC) is used. The main control unit is designed for the parking garage control system. The main contents of the thesis research are:
1.Conduct research on the types of mechanical parking garages, the development
status at home and abroad, and the problems in the development of China's industries.
2.A three-row, three-row, 6+6+9, twenty-one parking space is designed to study the
overall structure of the three-dimensional parking garage and its operating principles.
3.Design the hardware system of the lift-and-throw parking garage. The contents include: the main circuit design, manual control system design, PLC peripheral hardware design, drawing the garage main circuit diagram, manual control circuit diagram and PLC peripheral circuit wiring diagram.
4.Design the software system for lifting and moving the three-dimensional parking
garage. The contents include: the overall introduction of PLC, the choice of PLC programming language, the design of the main flow chart of the program, the flow chart of each basic function program, and the preparation of the ladder diagram program according to requirements.
5. Use S7-200 simulation software to carry out on-line simulation and debugging
of lift-and-push parking garage.
This paper focuses on the design of the hardware and software system for the overall structure and control system of the lift-and-throw stereo garage. The design process adopts a modular design concept and has a flexible structure. Through the design and optimization of the PLC software system, the three-dimensional parking garage has an intelligent control function, and the three-dimensional parking garage parking space can be safely, stably, accurately, and quickly moved to. At the intersection of people and vehicles, access to vehicle operations. The three-dimensional parking garage gives full play to the spatial advantages of land resources and greatly improves the space utilization of land resources. It is an effective solution to the problem of parking difficulties in large and medium-sized cities.
