创新训练家用电风扇的无线遥控电路课程设计报告姓名：学号：指 导 教 师 ：学院：机电工程学院专业：机械设计制造及其自动化完 成 日 期 ：2014 年 7 月 5 日摘要系统采用了 PT2262 和 PT2272 作为无线发射和接收，和单片机AT89S52 作为控制系统，现简单地介绍了红外线遥控发射、接收系统的原理，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。 遥控电风扇控制系统分为两大部分：遥控器和电风扇控制板，下面分别加以描述。关键字： PT2262、PT2272、AT89S52 Summary The system USES PT2262 and PT2272 as wireless transmission and reception, and monolithic integrated circuit AT89S52 as control system, is simply introduces the infrared remote transmitting and receiving system, and the principle of 51 assembler code intact. Including transmitting and receiving the principle diagram and the programming of the main program, sending and receiving procedures, timing program interrupt program flow process, thus completing the design process, the main points of reference block design process, can write applications. Remote electric control system is divided into two parts: the remote control, and the fanner described below respectively.
