Method, system and device for transmitting data at two ends of train and medium

Abstract

The invention discloses a method, a system and a device for transmitting data at two ends of a train based on a millimeter wave antenna, and a medium. The method comprises the following steps: receiving a first original signal sent by a first vehicle-mounted radio control unit; converting the first original signal into a first radio frequency signal; transmitting the first radio frequency signal to a receiving end through a millimeter wave antenna, so that the receiving end converts the first radio frequency signal into a first original signal and transmits the first original signal to a second vehicle-mounted radio control unit; wherein the frequency of the first radio frequency signal is different from that of the second radio frequency signal transmitted by the millimeter wave antenna of the receiving end. The millimeter wave antenna transmits the radio frequency signals to realize transmission of data at two ends of the train, and the first radio frequency signal and the second radio frequency signal are different in frequency, so that the situation that data transmission is affected due to mutual interference of the signals when the radio frequency signals are transmitted at two ends simultaneously is avoided; meanwhile, the wireless transmission mode solves the problems that engineering wiring is difficult and later maintenance is difficult when data at the two ends of the train are transmitted through optical fibers.

Description

technical field [0001] The present application relates to the field of rail transit communication, in particular to a method, system, device and medium for data transmission at both ends of a train. Background technique [0002] In order to ensure the safety and reliability of the maglev train operation, the wireless communication system of the maglev train adopts a dual-network redundant system architecture and is divided into several partitions. The single partition system includes: partition radio control unit (Decentralized Control Unit, DRCU), ground Fixed base station (Railway Base Station, RBS), ground optical fiber network (Optical Fiber Network, OFN), vehicle radio control unit (Mobile Radio Control Unit, MRCU) and vehicle mobile base station (Mobile Base Station, MBS). Among them, the MRCU is installed at both ends of the train, that is, the head car and the tail car. [0003] In order to realize the synchronization of data at both ends of the train, the data betw...
