【摘要】：为构建稳健的远程数据传输系统,设计并实现一种基于北斗短报文协议的可靠远程通信系统。针对北斗短报文通信不可靠和通信容量有限的局限性,采用丢包反馈重传机制完善数据传输的可靠性,运用粘包机制提高小数据传输效率,根据分包机制实现大数据的正确传输。将北斗短报文通信协议的电文内容进行扩充,自定义系统通信协议,设计开发一款嵌入式通信接口机,并给出相应的管理机制。通过将北斗通信接口机作为数据传输中介进行实验,结果表明,丢包反馈重传机制比无反馈机制的丢包率平均降低46.877%,能保证北斗远程数据传输的可靠性。
[Abstract]:In order to construct a robust remote data transmission system, a reliable remote communication system based on Beidou short message protocol is designed and implemented. In view of the unreliability of Beidou short message communication and the limitation of limited communication capacity, the reliability of data transmission is improved by using packet loss feedback retransmission mechanism, and the efficiency of small data transmission is improved by using sticky packet mechanism. According to the subcontract mechanism to achieve big data's correct transmission. This paper extends the message content of Beidou short message communication protocol, defines the system communication protocol, designs and develops an embedded communication interface machine, and gives the corresponding management mechanism. By using Beidou communication interface as a data transmission intermediary, the results show that the packet loss feedback retransmission rate is 46.877% lower than that without feedback mechanism, and the reliability of Beidou remote data transmission can be guaranteed.
