毕业论文 采用单片机控制的红外自动门 摘要自动化、信息化程度越来越高，单片机的应用领域也就越来越广，成为人们生活不可或缺的一部分。随着社会的发展、科技的进步以及人们生活水平的逐步提高，各种方便于生活的自动控制系统开始进入了人们的生活，以单片机为核心的自动门系统就是其中之一。同时也标志了自动控制领域成为了数字化时代的一员。它实用性强，功能齐全，技术先进，使人们相信这是科技进步的成果。它更让懂得，数字时代的发展将改变人类的生活，将加快科学技术的发展。通过对“自动门单片机控制系统”的研究和设计，本论文着重阐述了以单片机为主体，电机为心的系统。本设计主要应用作为控制核心，电机、红外传感器、磁开关结合的系统。充分发挥了单片机的性能。其优点硬件电路简单，软件功能完善，控制系统可靠，性价比较高等特点。关键词片机自动门电机红外传感器Abstract In todays increasingly high degree of automation, informationization, application field of SCM is more and more widely, become an integral part of peoples life. Along with the development of society and science and technology, the progress of science and technology, and improve the peoples living standard, convenient to gradually, the automatic control system of life into peoples life, based on singlechip automatic system is one of them. Also marks the automatic control field became a member of the digital age. It is practical, complete functions, advanced technology, make people believe that it is the results of scientific and technological progress. Let us know more, and digital age will change the development of human life, will speed up the development of science and technology. Based on the automatic control system of research and design, this paper mainly discusses the microcontroller as main body, dc motors, speed measurement as the core of the automatic operation system. This design is mainly used as control core and AT89C52 dc motor, infrared sensor, the combination of magnetic switch system. Give full play to the chip. The advantages of simple circuit hardware, software function perfect, reliable, cost-effective control system is higher characteristic.
