闭路电教系统双向控制通信链路的简单实现

A simple realization of bi directional control communication link for Audiovisual Education System

提出了一种简易实用的闭路电教系统双向控制通信链路.详细分析探讨了红外遥控系统指令的编解码特征,讲述了软件指令解码与恢复方法,同时给出软硬件的具体实现.为电教设备的反向控制提供了一种新的手段.

This paper introduces a simple and practical bi directional control link for AVE(Audiovisual Education) System.The instruction codec character of Infrared Remote Controlling System is deeply analyzed and searched.The software instruction decoding and resumption method,and the realization of soft hardware is given. It offers a new method to reversal control for AVE equipment.
