传统解码方法存在只能针对特定振荡频率的波形进行解码的问题。为了改进传统解码方法的局限性.设计了一种基于单片机的具有自学习功能的集成编码芯PT2262解码器。该解码器实现了在未知发射电路的振荡电阻参数情况下,通过自学习获取参数并完成解码;同时,突破了传统解码方法中数据位只有4-6位的限制.12位编码数据帧格式可根据实际使用场合灵活定义。实验结果表明,在无线传输距离为200m的情况下,解码正确率为99.8%。

Traditional decoder method exists the problem that it only can be used for a particular oscillation frequency waveforms decoding. In order to improve its limitation, a kind of decoder with auto-study function for the encoding IC PT2262 was designed based on MCU. This decoder can accomplish decoding based on the parameters of Rosc which is obtained from transmitter circuit through self-learning, even though the oscillation resistance parameters of transmitter circuit were unknown. Moreover, it broke through the limit of only 4 to 6 data bit and the coded data frame format can be defined according to the application fields. Experiments show that decoding accuracy rate achieves 99.8 percent which under the circumstances of 200 meters tran...
