摘要
针对传统串口通信数据流校验方法存在识别数据能力差,校验平台智能分类效果不佳问题,提出一种Zigbee的串口通信数据流循环冗余校验方法。此次研究重新设计循环冗余校验码,基于Zigbee规划数据识别流程,通过设置循环冗余校验管理逻辑;在并行控制模式下,实现对串口通信数据流的循环冗余校验。为了验证串口通信数据流校验效果,设计对比实验。实验结果表明,此次基于Zigbee的校验方法,其识别信号波形的相似系数更接近1,该方法应用下,教学平台的智能分类效果更好。由此可见,Zigbee技术能够优化循环冗余校验法。
Generally,the traditional serial communication data stream verification method has some defects,such as poor ability to identify data and poor intelligent classification effect of verification platform.This paper proposes a Zigbee cyclic redundancy check method for serial communication data stream.Firstly,the CRC code was redesigned to identify the process according to Zigbee planning data,and the management logic was checked based on the setting of cyclic redundancy.Secondly,in parallel control mode,the cyclic redundancy check of serial communication data stream was completed.Finally,a comparative experiment was designed for verifying the effectiveness of the method.The results show that the similarity coefficient of the recognition signal waveform based on Zigbee is closer to 1,which indicates that the proposed method has good intelligent classification effect.Thus,it can be seen that Zigbee technology can optimize the cyclic redundancy check method.
