1、本科毕业设计基于PLC的立体车库设计30摘要立体车库是实现车辆自动存放的仓储设施。现代城市汽车保有量的不断增加,出现了乱停车和停车难的问题。机械式立体车库以其具有占用空间小、操作方便、使用安全等优点,成为解决城市停车难问题的有效途径。本文在对立体车库进行充分调研的基础上,选择典型的升降横移式立体车库为研究对象,简单地介绍了立体车库的特点和主体结构,同时阐述了升降横移式立体车库的工作原理,即通过载车板的移位产生垂直通道来完成上层车位存取车操作。本文从车库结构、传动系统、控制系统三方面对立体车库进行了设计。对包括框架结构、载车板在内的主体结构进行了研究和设计;在传
2、动系统的设计中,选用了合适的传动电机和传动链;立体车库控制系统中,采用了可编程控制器(PLC)控制。为了满足立体车库安全性的要求,选用了光电检测装置和防坠机构等安全装置。在理解立体车库控制功能及存取车流程的基础上,选用三菱FX2N型PLC编程软件,并对PLCI/O口进行了分配,设计PLC硬件接线图,最后利用梯形图编程语言编写了立体车库的控制程序。关键词:立体车库;可编程控制器;传动系统;梯形图30AbstractStereogarageisastoragewhichisusedforautomaticparking.Thereemergesdisorderly
