摘要
北斗通信传输数据拆包过程中易出现数据丢失情况,导致传输结果不精准,提出基于超远距离用电采集场景的北斗通信传输研究。按照超远程北斗通信传输框架,设计了超远距离信道端,并在其上设置了协议规约。按照北斗通信报文格式,按时序拆分长包,实现包的封装和解包。为北斗通信设计了窗口传输流程,并进行伪距修正,设计了请求重传处理,避免了数据丢失,完成了北斗通信的远程传输。由试验结果可知,该方法拆包情况与理想情况一致,且最大数据丢失量为5 byte,具有精准的传输效果。
Data loss occurred in the process of unpacking of Beidou communication transmission data,which led to inaccurate transmission results.A study on Beidou communication transmission based on ultra long distance power consumption acquisition scene was proposed.According to the transmission framework of ultra remote Beidou communication,the channel end of ultra long distance is designed and protocol protocol is set on it.According to Beidou communication message format,the long packets are split in time order to realize package and unpacking.The window transmission flow is designed for Beidou communication,and the pseudo distance correction is carried out.The request retransmission processing is designed to avoid data loss and the remote transmission of Beidou communication is completed.The results show that the unpacking condition of this method is consistent with the ideal situation,and the maximum data loss is 5 byte,which has the accurate transmission effect.
