Abstract
A train positioning method includes acquiring first device identification information at an antenna; acquiring train positioning information; after determining the first device identification information is trustworthy, storing the first device identification information and the positioning information in a non-volatile memory; after awakening the train from dormancy mode, receiving second device identification information using the antenna; according to the received second device identification information and the first device identification information from the memory, determining whether, after being awakened, the train is at the same position as before entering dormancy mode; upon determining that, after awakening, the train is at the same position as before entering dormancy mode, determining the current position and direction of the train match positioning information in the memory, and completing positioning of the train. This ensures the usage experience of users of a train. An apparatus, a system, and a computer-readable medium are also provided.
