自学习红外遥控器的设计与实现

通过对红外遥控器发射编码的分析,提出了一种以单片机AT89s52为核心的自学习型红外遥控器的设计和实现方案。在方案中采用测量脉冲宽度的方法来学习红外遥控编码,采用索引存储的方法来保存学习到的红外编码,采用单片机定时器来产生红外编码发射所需要的38khz红外载波。大量的实验数据表明,文章提出的设计方案解决了红外学习效率不高,存储空间利用率低的问题。特别是索引存储的设计方法对编码的成功学习和存储起到了关键作用,值得推广。

Design and Realization of a Learning Infrared Remote Controller

Through the analysis of the infrared emission coding, This paper presents a kind of design scheme of infrared remote controller based on the MCU AT89s52.In this paper, the remote controller learns infrared code by pulse width measuring, saves code by index, outputs carrier wave by timer.A large number of experiments show that the design proposed in this paper has solved the issues infrared learning efficiency not high, a low utilization rate of storage space.In particular the method of index storage played a key role during coding learned and saved successfully, it should be promoted.
