With the development of the society, the progress of science and technology and the improving of peoples living standard, all kinds of convenience in life start into the automatic control system of peoples lives, with the single chip processor as the core of the automatic door system is one of them. Also marks the automatic controlled field became a member of the digital age. Its practicability is strong, the function is all ready, technology advanced, make people believe its the result of scientific and technological progress. It is more to understand people, the development of the digital era will change human life, will speed up the development of science and technology. This paper focuses on the design with 89C52 as the main body, pyroelectric infrared sensor, dc stepper motor as the core of automatic door control system, etc. It give full play to the performance of the microcontroller, the advantages of hardware circuit is simple, software function is perfect, reliable control system, the characteristics of high cost performance, has certain use and reference value. Keywords automatic door; single chip microcomputer; stepping motor; pyroelectric infrared sensor 目 录 摘 要 I Abstract II 第1章 绪论 1 1.1 课题背景 1 1.2 自动门在国内外的发展状况 1 1.3 课题研究的意义和目的 2 1.4 主要研究内容 2 1.5 本章小结 3 第2章 系统总体设计方案 4 2.1 系统总体规划 4 2.2 器件介绍 4 2.2.1 89C52单片机 4 2.2.2 热释电型红外线传感器 8 2.2.3 步进电机 9 第3章 硬件设计 11 3.1 基本单片机系统 11 3.2 热释电红外检测电路 12 3.4 控制电路 13 第4章 软件设计 14 4.1 整体顺序流程图 14 4.2 功能模块程序 15 4.2.1 定义变量及主程序 1
