摘要

虽着科学技术的不断发展，人们对车库的需求量日益增长。现在拥有汽车的人越来越多，对好的车库门的需求也在不断增大。智能车库的应用也越来越广泛，停车场管理控制系统在建筑中是不可缺少的，同时也是建筑物智能化的重要指标。随着计算机控制技术的发展，停车场管理控制系统的功能及软硬件设施也伴随其发展而不断改进。本次课程设计主要阐述车库自动门的设计思想与程序编制，应用PLC自动控制技术实现自动控制车库门的打开或关闭。当车接近门时，通过驱动程序将门打开，离开后再将门自动关闭，并对开启和关闭的过程实现控制系统。此系统对车库的管理有很大的帮助、对疏导交通流量、提高道路通行能力有明显的效果，有很大的实用价值人们对车库的需求量日益增长。智能车库将是信息社会最重要的基础设施之一，停车场管理控制系统则是现代建筑中不可或缺的一部分。随着计算机控制技术的发展，停车场管理控制系统的功能及软硬件设施也伴随其发展而不断改进。自动门系统已开始于大型公司、科研所、政府机关等单位。为增强自动门运行的可靠性，本设计提出一种FX232MRplc与变频器控制的自动门控制系统，设计中采用两个感应探测器、一些开关及传感器作为此系统的输入设备，变频器作为调节门体速度，并分析了该控制系统的工作原理及系统的硬件组成，分析人体感应探测，自动门运行位置检测，门运行故障检测等控制电路的工作过程，正确PLC的选型、变频器的选型及自动门控制等方面进行详尽阐述。I/O结合PLC运行特点，对控制系统工作流程进行合理的优化。在此基础上给出控制系统软件的流程图。顺序功能图外部端子接线图以及PLC控制梯形图。

ABSTRACT

Title：Design of Automatic Door Control System Based plc ABS TRACT Abstract：

With the continuous development of science and technology, and now more and more people own cars, the garage door good demand is also growing. Application of intelligent garage is more and more widely, parking management system is indispensable in the building, also the important intelligent building. With the development of computer control technology, the parking lot management control system software and hardware facilities are also associated with its development and continuous improvement. Design and program design of this course focuses on the application of PLC automatic garage door, automatic control technology to realize the automatic garage door open or closed. When the car close to the door, opened the door to leave by the driver, and then the door automatically closed, and the control system to the process of opening and closing the implementation. Management of the garage in this system is of great help, has obvious effect on the traffic flow, to improve traffic capacity, is of great practical value. automatic door system has been applied to large companies research institutes government, agencies and other units are highly confidential. To enhance the reliability of automatic door operation, this design presents a FX2-32MR programmable logic controller and the inverter control automatic door control system, the design uses two sensor prods, some switches and sensors as the system input device, the dive door is used to adjust the speed, and analyzes the working principle of the control system hardware components and system, analysis of the human body decoction sensors automatic door operation position detection the door
