Reliable design of communication link for power emergency vehicle mobile station based on Beidou satellite

In order to establish a reliable power emergency communication network and speed up the efficiency of power rescue, a vehicle-mounted reliable communication link based on Beidou short message protocol is designed. Aiming at the unreliability of Beidou short message communication and the limitation of communication capacity, the enhanced data handshake mechanism is adopted to enhance the reliability of data transmission, and the multi-card cooperative transmission mechanism is adopted to improve the efficiency of data transmission. The example results show that the transmission success rate of the proposed reliable communication link is significantly higher than that of the traditional method, which can improve the reliability of mobile station data transmission and provide communication guarantee for power recovery.
