摘　　要：针对智能家居系统中红外设备控制的难题，文章主要介绍了一款基于STM32芯片所设计的红外收发模块。鉴于市场上红外编码的多样性，该模块采用数字计时的方式直接复制红外码，简化了红外学习算法；考虑到红外编码的长度及硬件的存储能力，文章介绍了一种简单有效的红外压缩算法。考虑到智能家居系统中红外设备与红外收发模块的距离，文章利用STM32的丰富内部资源设计了CAN2．0接口，实现了数字信号的远距离传输。文章简要介绍了一下该模块在智能家居系统中的应用。模块设计合理、原理简单，稍微改造一下即可作为万能遥控器。Specific to the problems of controlling infrared devices in smart home system,this article describes an infrared transceiver module based on the STM32 chip. According to the diversity of the infrared coding in market, digital timing to replicate the infrared codes to simplify the infrared learning algorithm; Taking into account the length of IR codes and hardware storage capacity, the article describes a simple and effective infrared compression algorithm. Taking into account the infrared devices in the smart home system and the distance of the infrared transceiver module ,using the rich STM32 internal resources, this article designs CAN2.0 interface, realize the digital signal transmitted over a long-distance. The article briefly describes the application of the module in the Smart Home system.The module design is reasonable, t simpleand low cost, slightly modified can be used as a universal remote.
