摘  要:本论文将用德国西门子PLC对M小区车库里本区车辆进出及停放指示、外部车辆进出停放收费、车辆全方位进行监控的方案，此方案不仅提高了设计效率，维护周期短而且调试方便，成本也比较低。同时更重要的是有利于管理者对的车库门车辆进出进行全方位的自动化控制，大大降低了人为工作强度以及出错概率。

　　　由于小区车库门控系统的必要性以及PLC独特的运算处理能力，因此本文设计自动控制车库门装置，它靠车辆检测器自动检测有无车辆通过，同时检测是否为本区内部车辆，进行判断分别管理车辆，车库内有全场监控视频，具有安装维护简单、方便可靠、安全等多种特性。

ABSTRACT:This paper will use to M community garage, Germany's Siemens PLC in vehicle access and parking instructions, external vehicles in and out of the parking charges, all-round monitoring scheme, this scheme not only improves the design efficiency, short maintenance cycle and debug is convenient, cost is low. At the same time is more important for managers to garage door vehicle in and out of a full range of automation control, greatly reduce the manual work intensity and probability of error. 

　　　Due to the necessity of community garage door control system and the PLC unique processing ability, this article designed automatic garage door control unit, it depends on the presence of vehicles by vehicle detector automatic detection, check for internal vehicle in this area at the same time, the judge management of vehicles, respectively, garage with full monitoring video, with a simple, convenient and reliable installation and maintenance, security, and so on many kinds of characteristics. 

Key words: PLC; depot; The garage door; control
