智能型红外遥控器中信号接收与压缩方法

Method of signal receiving and compressing in intelligent infrared remote controller

为设计基于网络的智能型红外遥控器,研究一种对原配遥控器遥控信号接收与压缩的方法。在分析研究红外遥控编码的基础上,针对编码格式多样无统一标准的特点,采用脉宽计数法接收遥控指令,这种方法通用性强,但其占用存储空间较大。针对单片机存储空间有限,提出结构识别均值压缩算法,能够高效压缩并复现数据。在BTF340开发板上搭建红外收发电路为实验平台,完成多种家电遥控器遥控指令的学习与复现。实验结果表明,该方法对红外遥控信号的接收、压缩、存储、发射均行之有效,具有很强的通用性。

To design intelligent infrared remote control based on the network,a method of the original remote control signal receiving and signal compressing was proposed.Based on the analysis of infrared remote control encoding,according to encoding format diversity and the characteristics of no unified standard,the pulse width counting method was used to receive remote control signals,which was universal,but occupied larger storage space.For the SCM limited storage space,the structure recognition mean compression algorithm was proposed so that data were compressed and replicated efficiently.On the BTF340 development board,the infrared transceiver circuit was built as the experimental platform to complete the study effectively and realize a variety of home appliances remote control.Experimental results show that the proposed algorithm is effective for the infrared remote control signal receiving,compressing,storing and transmitting and it has strong universality.
