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.
