摘　　要：9012型红外遥控器被广泛用在家用电器和仪器仪表中,在了解了其发射的编码脉冲信号波形后,设计了基于单片机AT89C51的红外遥控器解码器,对解码器硬件和相应软件进行分析并给出程序流程图。将红外遥控器用在生产即时显示系统中,作为参数设置和系统控制用红外遥控器,既操作灵活方便,又能提高系统抗干扰能力,在实际中收到了良好效果。The 9012 model infrared remote controller is widely used in family electric applianacs and instrument. After the code pulse signal waveshape that infrared remote controller emits is known, the decoder of infrared remote controller based on single chip microcomputer AT89C51 is designed,the decoder hardware and appropriate software are analysed and the program process diagrams are given. Putting the infrared remote controller to production--in time display system, it is put to parameter setting and system control, it is easy to handle and can improve capability of anti--disturbance, the good effect is acquired in practice.
