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， 同时指出在设计过程中应该注意的一些问题。通过实际搭建电路，音乐芯片 9300A产生的乐曲，通过调制 LED后发出，在一定的距离围之， 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。关键词：红外通信，调制
Design and Implementation of infrared communication transceiver system
Abstract:
In this
paper,
described
the
basic
working principle
of
infrared
communication,
completed
the
design
of
infrared
transceiver
’s
idiographic hardware circuit, and detailed description of the working
principle
of transmitting
and receiving,
also
pointed
out
that
during
the
design process
should
pay attention to some problems.
Through the actual
circuit structures, music 9300A chip generated music, through modulated
LEDand emitted
the music signal,
in a certain
distance
range, the receiver
can receive music signal, and the music signal can be broadcast without
distortion
with the
use of
loudspeaker.
Thereby
completing
the
transmitting and receiving of entire infrared communication system.
