Data transmission method of port railway transport train and locomotive communication terminal

The invention relates to the technical field of wireless communication, in particular to a data transmission method of a port railway transportation train and a locomotive communication terminal. Which comprises a ground master control system and a locomotive communication terminal, and is characterized in that a dual-communication transmission link is arranged between the ground master control system and the locomotive communication terminal, the dual-communication transmission link comprises a 5G communication link and a radio station communication link, and the locomotive communication terminal selects a corresponding communication transmission link by analyzing characteristics of locomotive data to be transmitted; the locomotive communication terminal controls establishment and disconnection of the 5G communication link and the radio station communication link and data transmission. According to the invention, a 5G/radio station double-link data transmission mode is adopted, while important information tr
