毕业设计 基于单片机的红外遥控电风扇控制系统设计 摘要 本文给出了红外遥控器信号发射原理、红外接收器接收原理及它们的连接方式和单片机软件解码应用程序，给出用 89C51发射遥控信号和89C2051作为遥控接收信号和系统解码器和的一种巧妙实现方法，以及完整的51汇编程序代码。包括发射、接收的原理图及其编程的主程序、发送程序、接收程序、定时中断程序的流程过程，从而完成此设计的要点，参考流程方框图的构思过程，可以编写应用软件。现代智能化仪器仪表系统、工业设备中的控制输入也较多地使用红外遥控器。红外遥控器基于其体积小、功耗低、功能强、成本低的特点，己经在家电产品设备中广泛应用。 关键字：红外遥控 软件编码 AT89C2051 AT89C51 ABSTRACT This article has given the infrared remote control signal launch principle, the infrared receiver connection way and the monolithic integrated circuit software decoding application procedure, Gives 89C2051 takes the remote control receiving system decoder one ingenious realization method, as well as integrity 51 assembly program code. Including launch, receive schematic diagram and programming master routine, calling order, receive procedure, fixed time interrupt routine flow process, thus completes this design the main point, the reference flow block diagram idea process, may compile the application software. Infrared remote control based on its volume small, power loss low, function strong, cost low characteristic, oneself after in electrical appliances product equipment widespread application. In the modern intellectualization instrument measuring appliance system, the industrial equipment control input also many uses the infrared remote control. In addition, in has the high pressure! Radiation! Has environment and so on in under poison gas and dust industrial equipment, the infrared remote control also by its reliable and characteristics and so on isolation electrical interference obtains the widespread application.
