摘 要随着科学技术的发展，自动门在人们日常生活的中断中得到了广泛的应用，同时对其安全性和各方面性能的要求也越来越高。随着人们对生活条件的不断追求，科技的不断发展，自动门控制系统也成为了一种与时俱进的高新技术产品。本文主要研究设计红外线自动门控制系统，通过红外线检测和AT89C51 实现整体控制系统，检测人体放射出的红外线能量的变化，转换成电信号，传送到单芯片微型计算机。 ULN2003 电机作为门驱动装置，用微型计算机控制交流电机，自动打开门，使人进入后可以自动关闭，对自动感应门的设计领域具有积极意义。关键词： 单片机；红外线传感器；AT89C51- I -AbstractWith the continuous development of science and technology, automatic doors have been widely used in the interruption of people's daily life. At the same time, the requirements for their safety and various performance are getting higher and higher. The control system of automatic doors is a high-tech product with the continuous pursuit of living conditions and the continuous development of science and technology. Due to the strong adaptability and high stability of single chip microcomputer system, AT89C51 single chip microcomputer is adopted as the main controller in this design.This design is an infrared automatic door control system, which uses an infrared sensor as a sensor to detect changes in infrared energy radiated by the human body, convert the changes into electrical signals, and transmit the electrical signals to a singlechip. The AC motor is used as the door driving device. The AC motor is controlled by a singlechip to automatically open the door, and the door can be automatically closed when a person enters the door. This subject mainly realizes infrared detection and MCU control system based on AT89C51.Key Words：MCU; Infrared sensors; AT89C51- II -（论文）目 录摘 要....................................................................
