摘　　要：采用AT89S52单片机作为系统的核心控制部分,根据PS/2协议采用红外遥控器作为键盘接口向PC机发送扫描码从而实现与PC机通信。该接口方式既可以节省单片机的硬件资源又能够在距PC机一定距离内通过无线控制方式对PC机进行操作,因此可以在工控以及多媒体教学领域等被广泛运用。Using AT89S52 Single Chip Micyoco （SCM） as the central control of the system and infrared ray remote as keyboard interface and based on PS/2 protocol, scan codes are sent to the computer and consequently communication is established. This interface mode can not only reduce hardware requirements for the Single Chip Micyoco （SCM）, but also can manipulate computer wirelessly within some distance. As a result, this design will find wide applications in industrial controls as well as in muhimedia teaching.
