 摘   要
 隨著汽車的急增致使城市停車難問題不斷惡化,而作為解決城市靜態交通的有效措施——向空間、向高層發展的自動化立體停車設備,以其占地面積少、停車率高、布置靈活、高效低耗、性價比高、安全可靠等優點,越來越受到人們的青睞。
 升降橫移式立體停車庫就其組成部分而言，可分為三大部分:車庫結構部分、傳動機構部分和控制系統部分。升降橫移式立體停車庫的控制系統則是整個車庫系統的另一個主要組成部分，這也是本文論述的重點，詳細地介紹了在實際的工程應用中，車庫控制系統的硬件配置以及軟件的設計。升降橫移立體停車庫以停放轎車為主,其代價較昂貴,而且立體停車庫使用時涉及到人身和車輛的安全,所以對設備的安全性和可靠性要求非常高。PLC采用了以計算機為核心的通用自動控制裝置,集微機技術、自動化技術、通訊技術為一體,可靠性強、性價比高、設計緊湊、擴展性好、操作方便,適用于頻繁啟動和惡劣的環境,因此在立體停車庫控制系統中通常采用PLC作為電控系統的核心，并根據車庫工作時輸入輸出的工作參量，完成可編程控制器的選型。PLC控制程序采用模塊化編程形式,車位運行過程中只需調用子程序模塊,這樣大大降低了程序的復雜程度,方便了程序的修改,而且為車位的拓展提供了便利的條件。停車庫控制系統的硬件和軟件相互依托，相互補充，才能有效地以最低的成本完成對車庫系統的控制。
 升降橫移式立體停車庫具有非常廣闊的發展空間和發展前景，其未來的發展方向就是要使停車庫實現真正的智能化，以互聯網為依托，實現網絡化。操作人可通過靈活多樣，比較友好的人機界面，監控停車庫的運行狀況以及對停車庫發送控制指令。

 Abstract
 Along with the unceasingly automobile quantity increases, the automobile parking location growth actually cannot with its synchronization. The automobile berth and automobile quantity serious imbalance, from this brings severe stops difficulty. Right at the moment, the automated three-dimensional garage, with its advantages of taking less space, large parking capacity, flexible layout, most reasonable price and its reliability, has then arisen at the historic moment and are welcomed by more and more people.
 According to the form of the up-and-down translational spatial car parking lot，it is made of three parts: parking lot structure part, driving-frame work part and control system part. The control system of up-and-down translational spatial car parking lot is another main part in the car parking lot system, which is the emphasis in this paper. This part focus on the hardware configuring and software design applied in the control system of the parking lot.
 As an automated computer-centered control device, PLC is equipped with the micro-technology, automated technology and telecom technology and can be applied in harsh environment. Therefore, in the practice of parking lot control system, PLC is commonly used as the heart of the system. PLC control system employs modularization programming, which makes the procedures much simpler, easier to be improved. The hardware and software of the parking lot control system complement each other, effectively controlling the parking lot system with the least cost.
 The up-and-down translational spatial car parking lot sees a wonderful prospect. Its application will fulfill the true intelligentization of the parking lot. The operator can keep it working properly and sending command by various, flexible and friendly communication interface.
