毕业论文（设计）基于单片机的红外线自动门控制.docVIP

摘 要 随着科技的不断发展，自动门在人们日常生活中断得到了广泛的应用，同时对其安全性及各方面的性能的要求越来越高。自动门的控制系统是随着人们对生活条件的不断追求，科技的不断发展应运而生的高科技产品。由于单片机系统的适应能力强，稳定性高，所以本设计采用STC89C52 单片机作为主控制器。 本次设计是红外线自动门控制系统，使用红外线传感器作为感应器，检测到人体辐射的红外线能量变化，将其转化为电信号，传给单片机，步进电机作为门驱动装置。通过单片机控制电机，使门自动打开，当人进门后又可以使门自动关闭。在开门时可以调节开门的速度，在关门时有防夹功能。另外本设计也可监测门内的温湿度并显示。本课题主要实现红外线检测和基于STC89C52的单片机控制系统。 关键词：单片机；热释红外线传感器；主控制器 Abstract With the continuous development of science and technology, automatic doors in the interrupt has been widely used, peoples daily life and every aspect of its safety and performance requirements more and more high. Automatic door control system is along with the people of the pursuit of better living conditions, the continuous development of science and technology arises at the historic moment of high-tech products. Because of the single chip microcomputer system adaptable, high stability, so this design uses the STC89C52 single-chip microcomputer as the main controller. Is this design infrared automatic door control system, the use of infrared sensors as sensor that detects human radiation of infrared energy changes, and convert it into electrical signals, to the step motor as drive door through the single-chip microcomputer control of the motor, the door opens automatically, when people after taking the door, can make the door shut down automatically. Can adjust the speed of the door when open the door, close the door when in the clamp function. In addition, our design can also be used in the monitoring of the gate of temperature and humidity and display.This topic is mainly to realize that infrared detection, and other based on STC89C52 single-chip microcomputer control system. Key words: singlechip; pyroelectric infrared sensors; main controller 目 录 第1章 概述 1 1.1 课题研究的可行性 1 1.2 自动门的发展 1 1.3 电机自动控制系统的应用和发展 2 1.4 课题研究的目的和意义 3 1.5 课题研究的要求和思路 4 1.6 毕业设计所要实现的功能 4 第2章 系统硬件设计 5 2.1 设计电路的框图和原理 5 2.2 单片机介绍 6 2.3 热释电红外传感器介绍 10 2.4 BISS0001芯片介绍和典型电路 11 2.5 步进电机 15
