摘　　要：本文从微控制器STC89C51出发,设计了一种基于SC9012编码芯片和BC7210解码芯片的红外遥控系统,并结合该系统介绍了一种未知编码脉宽信号的测量方法,提出了红外通信硬件接口电路的设计和软件实现。该方案已被成功地应用于MIDI音乐学习机的遥控系统。Beginning with a STC89C51 microcontroller, an infrared remote control system based on a SC9012 encoded chip and a BC7210 decoded chip is designed. A method for measuring the unknown encoded pulse width signal based on the system is presented. The design of an interface circuit for infrared communication hardware and its software realization are proposed. This scheme is used successfully in the remote control system of a MIDI music learning machine.
