摘　　要：介绍了一种红外遥控自学习模块,采用波形复制方法来实现红外遥控信号的载波识别与波形学习。该模块以STC12C5410AD单片机为核心设计,通过单片机的外部中断与定时器的配合使用,实现红外遥控信号的载波识别与波形学习。经过实际测试,该模块能准确学习红外遥控信号的波形,并能准确控制红外设备,具有良好的通用性和宽载波学习范围,可适用于万能遥控和智能家居系统。This paper describes a kind of the waveform replication method of infrared remote control self-learning module, which realizes infrared remote control signal carrier recognition and waveform learning. Regarding STC12C5410AD SCM as heart of designing, this module not only brings about infrared remote control signal carrier recognition and waveform learning by combining external interrupt and timer. Having been tested, this module can precisely study waveform of infrared remote control signal and control infrared equipment. It has good versatility and wide range of learning carrier. What＇s more, it can be applied to universal remote control and smart home system.
