摘要:本论文基于最近人们对于门的创新自动门的设计所展开的,对于自动门而言,它是通过物体的辐射的原理,达到无人操作实现门在人靠近的时候自动打开,在人离开门的时候自动关闭,全程不需要认得参与,方便快捷。在这里我使用到了STC90C516RD+单片机,热释红外点传感器硬件电路等一系列的设计来达到自动门控制系统的完成。本论文设计结果为,在单片机输入程序后,红外探测头感应到人的存在导致电机正传开门LED灯亮,在人离开门的时候,LED灯灭,电机反转关门的过程。62255

Intelligent infrared control door system
Abstract:In this paper, based on recent people for innovation design of automatic door the door, the door's history can be traced back to primitive society, people for safety experience more and more deep, from the very beginning the safety concept of automatic door convenient people's life up to now. For the automatic door, it is through the principle of radiation of the object, to achieve unattended operation to realize automatic door when people close to the open, when people leave the door shut down automatically, don't need to know to participate in all the way, convenient and quick. Here I use the STC90C516RD + MCU, the point of pyroelectric infrared sensor hardware circuit and a series of design to achieve the completion of the automatic door control system. As a result, this thesis design after the input program MCU, infrared detection head induction to man's existence, buzzer rang rang after 2 seconds, stop, this represents the door is fully open, when people from leaving the confines of inductive probe, buzzer rang, on behalf of the closing of the door slowly.

1引言
本篇论文所要论述的的是门的一种特殊形式,它是人类在现今社会下方便生活所创造而出的门即自动门,自动门所实现的功能与一般门大相径庭,但是它更加的自动化智能化而且节省人力。自动门的概念可以归纳为:在人们靠近门或者远离门的时候(或者说是对门实现开关动作的授权)门可以将这种信号自动甄别为开关门的控制信号亦或称之为控制单元。通过驱动装置以实现门的打开,在人远离门之后可以让门自动的关闭,那么这一个门的开关过程得以实现的系统就是本论文所设计的目的。
