基于PLC的立体停车库系统设计 摘要 ：The Design of a Stereo Garage System Based on PLC Abstract This paper analyzed the structure of a variety of parking garages. It includes the parking systems theory, an overview of the type and characteristics. By comparing the characteristics of a variety of solid garage, we draw a conclusion that parking garage can lift and transfer is the best choice for Ordinary household plot. In addition, it described how the new Stereo Garage System works in detail. Then, it illustrates the movement characteristics and functional requirements of this new solid garage. Again, the general scheme of the control system has determined. It introduced the components of the Stereo Garage and described the hardware and software components in detail. It explored the methods and procedures to achieve this new parking garage that controlled by the programmable logic controller PLC. Throughout this article, including selection, work steps, working principle and work characteristics of the PLC. According to the working process of solid garage, I draw a whole flowchart of the parking garage based on PLC and wrote the block diagram. This new solid garage has an important reference for the research of parking garage in the future. Key words: PLC, Automatic control, Parking, Lifting and Transferring 目 录 第一章 绪论 1 1.1 课题研究背景 1 1.2 课题的提出及意义 1 1.3国内外车库发展现状 2 第二章 立体车库总述 3 2.1立体停车库的分类及特点 3 2.2 车库的选型 6 2.3 升降横移式立体车库的结构组成 7 2.3.1 主框架部分 7 2.3.2 载车板部分 7 2.3.3 传动部分 7 2.3.4 控制部分 8 2.4 车库整体结构设计与运行说明 8 2.5 小结 8 第三章 升降横移式立体车库系统设计 9 3.1 动力系统设计 9 3.2 检测系统设计 10 3.2.1利用光电传感器的检测 10 3.2.2 载车板到位的检测 12 3.3 本章小结 12 第四章 基于PLC的控制系统设计 13 4.1 PLC的控制过程 13 4.2 控制板设计 14 4.3 I/O口的分配 15 4.3 PLC的选型 16 4.4 PLC外围接线图 16 4.4 PLC程序编写 18 4.5 本章小结 19 第五章 结论 20 参考文献 21 谢辞 22 第一章 绪论 1.1 课题研究背景 近年来，随着经济的迅速发展，城镇化、机动化进程不断加快，我国逐步进入小康社会，拥有家庭轿车已成为大多数中国人追求的人生目标。但是，随着汽车保有量的快速增长，在中国的各大城市中普遍存在着交通拥挤的现象，尤其是发达地区，停车越来越难。跟具调查，除厦门以外，在我国没有一个城市的车位满足率能够达到85%。不仅像北京、上海、广州、深圳这样的一线城市无法满足“一车一位”的要求，就连成都、杭州等二线城市的车均拥有停车满足
