Multi-channel transponder message transmission device and multi-channel transponder message transmission method

Abstract

The invention discloses a multi-channel transponder message transmission device and a multi-channel transponder message transmission method, which realize ground transponder energy emission, ground transponder message information wireless receiving, safe decoding and reliable transmission. When a certain part of the equipment breaks down, the equipment is automatically guided to the safety side, the equipment transmits the information to the vehicle-mounted control equipment at the rear end in real time through other normal channels, and meanwhile real-time detection, fault protection and recording can be conducted on equipment state information. The equipment comprises a vehicle-mounted host and a vehicle-mounted antenna, wherein the vehicle-mounted host comprises a dual-channel power amplifier module, a multi-channel receiving module, a multi-channel processing module, a recording board, a power board and a bus board. The device and method have the advantages that the equipment adopts a multi-channel, modular and multi-layer protection design, and avehicle-mounted host processing module adopts a two-out-of-two and double-path backup design, so that the safety, reliability, availability and maintainability of the equipment and the real-time performance, accuracy and stability of information transmission are improved.

Description

technical field [0001] The invention belongs to the application field of rail traffic safety control, and in particular relates to a multi-channel transponder message transmission device and method. Background technique [0002] During the development of railway transportation, transportation safety has always been the most concerned topic. With the continuous improvement of the national economy's requirements for railway transportation, the requirements for railway train operation management and safety control are also continuously improved. According to the requirements of ERTMS / ETCS (European Railway Transportation Management System / European Train Control System), the railway department has formulated the standard of China Train Control System (CTCS standard). In this standard, BTM (Balise Transmission Module) plays a vital role in activating, receiving, and analyzing the message information sent by the ground transponder and transmitting it to the vehicle control equipm...

AI Technical Summary

Problems solved by technology

Due to the lack of transmission channels in the existing BTM equipment, the failure of a single component of the equipment may cause the overall failure of the BTM, and due to the large number of BTM equipment components and external interference, BTM has poor reception and transmission of transponder messages during operation. probability, which may result in loss of transponder information

The loss of transponder information will affect the control of the train by the train operation control system, and in severe cases will trigger the train brake, thus affecting the safety of railway traffic and transportation efficiency
