【摘要】 设计了一种红外学习系统,采用波形完全复制的方式实现红外遥控信号的载波识别。该系统以低功耗STM32F0为核心,通过串口通信,定时器输入捕获中断,Flash存储实现红外脉冲信号的自学习,并以软件形式实现38 k Hz载波。经试验测试,所设计的红外学习系统能学习不同类型的红外编码,并准确还原、发送红外信号。随着智能家居的普及与发展,设计具有广阔的市场应用前景。更多还原

【Abstract】 An infrared learning system was designed to realize the carrier identification of infrared remote control signal by means of complete waveform duplication. The system took low-power STM32F0 as the core to achieve self-learning infrared pulse signal via serial port communication,interrupt captured by timer input and flash memory while 38 kHz carrier wave was realized in the form of software.The experimental test showed that the designed infrared learning system can learn different types of infrared coding and the infrared signals can be restored accurately for transmission. Along with the popularization and development of smart home,this design has a broad market prospects.更多还原
