毕业设计-基于单片机的红外线解码系统设计，共14页，6867字
摘 要：
本文在通用红外遥控系统的基础上，利用单片机外部中断的原理设计了一款遥控开关。在设计中，将红外遥控接收部分通过单片机MCS51来控制，即当一体化红外接收器接收到红外遥控信号后,将光信号转变成电信号，经放大、解调、滤波后,将原编码信号送入单片机MCSC51中进行信号识别、解码，然后进行相应的处理，以达到控制电路的目的。

SCM-based Infrared Remote Control Switch
Abstract:
This paper employs the principle of external interruption in SCM to design a remote control switch based on general infrared remote control system. In this design the infrared remote control receiver is controlled by SCM MCSC51.that is, when the integrated infrared receiver receives infrared remote control signal, the light signal will be turned into electronic one which is consequently amplified, demodulated, filtered and transferred into SCM MCSC51 to be identified, decoded and proceeded correspondingly, so as to control the circuit.
