本科毕业论文 （2011届） 题 目 机械式立体停车库下位机系统设计 学 院 机械工程学院 专 业 机械设计制造及其自动化 班 级 学 号 学生姓名 李纯彬 指导教师 颜志刚 完成日期 2011年6月 摘要 随着我国经济的飞速发展，汽车保有量的不断增加，停车难已成为一些大城市的问题。国外的许多城市，也存在停车难的问题。世界各国在解决这一难题中采取的措施有所不同，但机械式立体停车库的应用是各个国家都积极采取的解决办法。 垂直升级式停车设备是一种机械式立体停车设备，本文针对自行设计的一种新型垂直升降式停车设备的结构特点及其对控制系统的要求，提出了停车设备单片机控制系统方案和电力拖动系统方案；进行了控制系统软硬件方案设计和调速方案设计；最后对研究工作做了总结和展望。 本文提出了一 种单片机控制系统方案，完成了系统硬件电路原理图的绘制；软件的设计。 根据停车设备运行特点和电气控制要求提出了系统电力拖动方案。该方案确定了电力拖动系统的组成:选择了电机和各低压电器；确定了停车设备运行速度曲线。 关键词：停车设备；单片机；控制系统 Abstract Along with speedily developing of our country economy and the automobile in the city-retained amount having sharp increase，the difficult problems of city parking has appeared．In addition，many foreign cities lack of parking place also．Though that country of the world adopts different solution，application of the space-parking system is unified method． The vertical lifting parking equipment is one type of the mechanical parking equipment.According to the structural traits of a new type of vertical lifting mechanical parking equipment designed by us and the requirements to the control system, a kind of single-chip microcomputer control system scheme and a electric power draw system scheme are developed in this paper; The control systems hardware and software scheme are designed; In the end,the summary and the prospect to this papers study work is given. A single-chip microcomputer control system scheme is presented in this paper; the design and the drawing of hardware circuits is made; the software program is compiled. Based on the parking equipments working traits and the requirements of the electrification control, the electric power draw system scheme is developed. The scheme determines the component of electric power system, the selection of electrical machinery and all kinds of low pressure electrical equipments, the determination of working velocity.
