機(jī)械式立體停車庫下位機(jī)系統(tǒng)設(shè)計

摘要
隨著我國經(jīng)濟(jì)的飛速發(fā)展，汽車保有量的不斷增加，停車難已成為一些大城市的問題。國外的許多城市，也存在停車難的問題。世界各國在解決這一難題中采取的措施有所不同，但機(jī)械式立體停車庫的應(yīng)用是各個國家都積極采取的解決辦法。   
垂直升級式停車設(shè)備是一種機(jī)械式立體停車設(shè)備，本文針對自行設(shè)計的一種新型垂直升降式停車設(shè)備的結(jié)構(gòu)特點及其對控制系統(tǒng)的要求，提出了停車設(shè)備單片機(jī)控制系統(tǒng)方案和電力拖動系統(tǒng)方案；進(jìn)行了控制系統(tǒng)軟硬件方案設(shè)計和調(diào)速方案設(shè)計；最后對研究工作做了總結(jié)和展望。
    本文提出了一 種單片機(jī)控制系統(tǒng)方案，完成了系統(tǒng)硬件電路原理圖的繪制；軟件的設(shè)計。
    根據(jù)停車設(shè)備運(yùn)行特點和電氣控制要求提出了系統(tǒng)電力拖動方案。該方案確定了電力拖動系統(tǒng)的組成:選擇了電機(jī)和各低壓電器；確定了停車設(shè)備運(yùn)行速度曲線。 

關(guān)鍵詞：停車設(shè)備；單片機(jī)；控制系統(tǒng)
 
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 system's hardware and software scheme are designed; In the end,the summary and the prospect to this paper's 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 equipment's 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.

Key words:parking equipment；single-chip microcomputer；control system
