摘要
本文阐述了红外通信的基本工作原理，完成了红外收发器具体的硬件电路设计，并且详细说明了发射和接收的工作原理。通过实际搭建电路，以音乐芯片为例，通过调制LED后发出，在一定的距离范围之内，接收端可以接收到乐曲信号，利用喇叭可以将乐曲信号无失真的播放出来。从而完成了整个红外通信系统的收发。
This paper describes the basic working principle of infrared communication,complete an infrared transceiver specific hardware circuit design,and detailing the transmitter and receiver works.Set up by the actual circuit,music chip,for example,by modulating the LED after the issue,at a certain distance range,the receiver can receive the music signal,the use of horn music can be played back sim^al without distortion.Thus comDleting the entire infrared communication system transceiver.
