基于PLC控制五车位的立体停车库设计.doc

I 提要我们知道随着人民生活水平的日益提高,城市汽车的数量也在不断增加,而土地资源却十分有限,自然停车难问题己经渐渐成为大中型城市的一个普遍现象。机械式立体车库可充分利用上地资源,发挥空间优势,最大限度地停放车辆,成为解决城市静态交通问题的重要途径。本课题以较为典型的升降横移式立体车库为研究对象,综合考虑立体车库制造成本和运行效率的双重因素。本文在对国内外车库现状及发展趋势做了充分调研的基础上,选择两层五车位车库结构为研究模型。升降横移式立体车库就其组成部分而言,可分为三大部分:车库结构部分、传动机构部分和控制系统部分。本文简单介绍了车库的主体结构和特点, 对车库的控制系统也作了详细的说明,依据升降横移式立体车库的运行原理,运用力学理论对升降横移式立体车库的结构进行了全面的力学分析,包括升降横移式立体车库的框架结构的强度、横移传动系统中轴的强度和升降传动系统中轴的强度等。在对升降横移式立体车库控制系统的设计中,采用了先进的 PLC 控制, 运用西门子公司的编程软件编制了升降横移式立体车库控制系统的程序, 并经调试、运行, 证明采用可编程序控制器(PLC) 作为控制系统简单易行。其稳定、可靠、快速、性价比高的特点使得控制系统非常完美。为了使停车设备满足使用要求,根据国家关于机械式停车设备通用安全要求的标准、升降横移式立体车库的实 II 际,在升降横移式立体车库中使用了一些必要的安全技术,这样保证了车辆的绝对安全,使得整个车库可以安全平稳的运行。关键词: 立体车库,控制系统,可编程序控制器,钢结构。 3 Abstract : We know as the quantity of urban automobile has inc reased continuously in nowadays, but the land resource is very limited and the hard-to-Park Problem has e mon phenomenon. Mec hani c al stereo garage can use land resource sufficiently and bring space advantage into play, and maximize the number of parking cars. It has e an important way for static traffic problem of cities. The issue studies the typ e mechanical parking system which named up-down and translation stereo garage, and regards of the two factors of cost of manufacture and operational efficiency synthetically. On the basis of investigation on current situation and developing trend of garage in domestic and abroad, we choose t wo -layer and three-formulistic garage structure as the research model. According to the form of the dragging-forms of multi player up-down and translation ear-base, it is made of three parts: part of ear - base stru c ture 、 part of driving-framework and part of control system. The paper simply introduces main structure and characteristics of garage and also gives a short introduction to its control system. The finite element reliability checking of steel structure of garage is utilized according to the operation principle of up-down and translation stereo garage, the mechanics was used prehensively analyze the up-down 4
