基于PLC的升降横移式立体车库
摘要：当前我国经济社会发展迅猛，人们的生活水平日新月异，汽车保有量不停增长，立体车库等特车设施的建设已远落后于汽车数量的上升，造成城市中违法违规停车的现象频发。升降横移式立体车库具有高性能、高空间利用率等特点，可以有效解决这些问题。所以本文以典型升降横移式立体车库为研究对象，通过实现车辆的自动存取，展现PLC控制技术在立体车库方面的应用。
本文通过分析国内外现有立体车库的特点，以典型的双层三列五车位升降横移式立体车库为研究方案，主要介绍了升降横移式立体车库的主体结构及工作原理，确定了以PLC为主控单位的控制方案，并对控制系统的工作过程进行了介绍，选用S7-200系列PLC，完成了控制系统的输入、输出分配和PLC选型，设计了控制系统的程序流程图，完成了立体车库控制系统的程序梯形图，完成了立体车库控制系统设计。

1.绪论
1.1本课题设计的意义
伴随着改革开放的深入，中国经济水平取得了巨大发展，国民生活条件日益提高。伴随着汽车工业的发展，汽车走进了千家万户，私家车保有量日益增加，然而与之矛盾的是城市停车位的缺乏。据了解，2010年中国私家车饱有量到达5900万辆，而2016年中国私家车饱有量高达1.46亿辆。据统计，100万辆汽车会占用1920万平方米的土地，这无疑是对土地资源的巨大浪费。并且，汽车占道停放加剧了路线的拥挤，汽车被盗被撞的情况也时有发生，同时汽车的乱停乱放对城市的市容市貌也产生了不好的影响。
