介绍了一款以AT89S52微处理器为核心的自学习型红外遥控器的设计与实现。该遥控器采用测量脉冲宽度的方法,可学习并存储其它遥控器的编码信息,利用存储的遥控编码信号控制相应的器件,达到用一个遥控器代替多个遥控器来控制不同家电的目的。文章对红外编码解码原理做了简要阐述,重点给出了遥控系统的硬件结构和软件流程,测试结果表明该智能遥控器具有操作方便、运行稳定和接收数据准确的优点。

A kind of design and implementation of intelligent infrared remote controller based on 51 series MCU was presented.The remote controller with self-study function which is implemented by pulse width measuring,has the ability to receive and learn the code of infrared instructions from others and repeat it again.So we can use only one remote controller instead of several to control many different electro-appliances.In this paper,infrared coding principle was briefly described,the focus is given to a remote control system hardware and software flow structure,test results show that intelligent remote control is easy to operate,works stably,and can receive data accurately.
