基于三菱PLC大厅自动门系统的控制设计 毕业论文+任务书+CAD图纸+程序+参数说明
摘 要
本论文主要是对门的自动开、关控制而论。自动门控制装置系统由检测元件光电传感器、继电器、可编程序控制器（PLC）、电动机组成。
当有人进入红外线传感器椭圆阴影区域时，开启电机启动，门自动打开，直到碰到开门极限停止。到达开门极限处7秒后，若无人在红外线传感器椭圆区域，关门电机启动，门自动关上，直到碰到关门限位开关。若在关门过程中，有人进入红外红外线传感器椭圆区域，门应立即停止关闭，执行开门的动作。

ABSTRACT
This paper is mainly about the automatic opening and closing control of the door. The automatic door control device system is composed of the detector element photoelectric sensor, the relay, the programmable controller (PLC), and the electric motor.
When someone enters the elliptical shadow area of the infrared sensor, the opening motor starts and the door opens automatically until the opening limit stops. After 7 seconds of reaching the opening limit, if no one is in the oval area of the infrared sensor, the closing motor starts and the door closes automatically until the closing limit switch is encountered. If someone enters the oval area of the infrared sensor during the closing process, the door should stop closing immediately and perform the action of opening the door.
