文章介绍了电脑遥控系统的组成及其原理。电脑遥控发射器产生脉位编码脉冲，发射红外遥控信号；遥控接收器将红外遥控信号放大、解调还原成遥控编码信号，经遥控接口电路将串行遥控编码信号转换成并行信号，通过中断响应和程序运行，执行遥控操作功能。
The paper introduces the composition of computer remote control system and its principle. The remote control receiver amplifies and demodulates the infrared remote control signal into a remote control coded signal, converts the serial remote control coded signal into a parallel signal through a remote control interface circuit, and sends an infrared remote control signal through an interrupt response And program running, perform remote control functions.
