摘　　要：提出了一种用于智能家居的低成本学习型遥控器解决方案。利用被控设备自备的红外接收器,无需内置任何被控设备的红外控制指令集,采用脉宽测量与模仿可完全实现自动学习的功能。同时还对测量数据进行了编码压缩,用软件模拟38 kHz载波信号的发送,节省了数据存储空间和设计成本。结果表明,该设计价格低廉,使用方便,完全具备自学习功能,可以代替各种遥控器实现智能家居遥控器一体化的要求。A solution of self-learning infrared controller for intelligent household with low cost was put forward. It made use of infrared receivers that was put inside controlled device without any built-in infrared instruction set of controlled device, and use pulse width measurement and imitation to realize self-learning function completely. At the same time, the measured data was encoded and compressed, and software was used to simulate the send of 38 kHz carrier signal which save the data storage and the design cost. Results showed that the infrared controller had low cost, easily use and self-learning function, so it could replace any kind of remote control to realize the integration of intelligent household and remote control.
