摘 要随着数字技术的快速进展，数字技术被广泛应用于智能控制的领域中。单片机以体积小、功能全、价格低廉、开发方便的优势得到了许多电子系统设计者的青睐。它适合于实时控制，可构成工业控制器、智能仪表、智能接口、智能武器装置以与通用测控单元等。本文首先阐明了近年来移动门的进展与意义，随后着重介绍了单片机控制的移动门系统所用到的集成芯片 AT89C52、红外线收发器等硬件的结构原理。文中采纳分块的模式，对整个系统的硬件电路进行分析，分别给出了系统总体框图、电源电路、红外线对射检测电路、电机控制电路，并对相应电路设计进行了相关的阐述。随后讲述了软件的编写思路，每一个模块都画了软件流程图，看起来一目了然。关键词：无线收发 红外对射检测 AT89C52AbstractWith its rapid development, digital technology is widely used in the field of control system. Single chip microcontroller is favored by many electronic system designers for its smallness, full function, low price and easy application. Its pretty fit for real-time control as a core in industrial controller, intelligent apparatus, intelligent interface, intelligent weapon device, universal measure control unit, etc.This paper first illustrates the development and significance of the platform screen door industry in recent years.And then foucuses on the structural principle of the integrated chip AT89C52 used in the development of microprocessor controlled controlled infrared automatic platform screen doors,infrared transmitting and receiving and other hardware.Used in block mode,the entire system hardware circuit analysis, given the overall system block diagram,the power circuit,IR remote control circuits,motor control circuits,and circuit design related expounded .Then tells the software to write ideas,each module are drawn from the relaxation of the diagram,look at a glance.Keywords:The wireless transceiver Infrared detectionAT89C52毕业设计（论文）原创性声明和使用授权说明原创性声明本人重...
