Balise message detection method and third-party balise message reading device

Abstract

The invention relates to a balise message detection method. The method comprises the following steps that: firstly, an existing balise transmission module (BTM) vehicle-mounted antenna emits a power signal to a ground balise in real time; and when being activated by the power signal, the ground balise sends out message data stored in the ground balise; and secondly, at least one small receiving antenna is arranged at a place at a distance no less than 50 millimeters in front of or in rear of the existing BTM vehicle-mounted antenna; to be specific, the BTM vehicle-mounted antenna receives the message data and sends the data to a BTM host for parsing, and the message data that have been parsed by the BTM host are sent to a train controlling computer; and the small receiving antenna receives the message data and sends the data into a vehicle-mounted receiving decoding device for parsing, and the message data that have been processed by parsing by the vehicle-mounted receiving decoding device are sent to a third-party balise message reading terminal for application. The provided method has the advantage that: the method is independent to the existing balise message device of the train, so that independent reading and application of the balise message by the third party can be realized.

Description

Technical field [0001] The invention belongs to the application field of railway transponders, and specifically relates to a method and device for reading transponder messages. Background technique [0002] The transponder transmission unit (BTM) is one of the key equipment of the vehicle-mounted equipment of the EMU. The vehicle-mounted BTM host, the transponder antenna and the ground transponder form a point communication system. In recent years, the railway department has formulated the Chinese train control system standard (CTCS standard) in accordance with the requirements of ERTMS / ETCS (European Railway Transportation Management System / European Train Control System). In this standard, the transponder will be used as a necessary equipment to further improve the degree of automation of the train control system. It will also make the application level of my country's train automatic control system move to a higher level, and the safety of railway transportation will be improve...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing transponder detection devices of EMUs are installed and configured with the EMUs at the factory, and their communication interfaces and application customers are fixed. If there is a third party that needs to apply the message data of the transponder, the current on-board transponder Transponder equipment cannot meet the requirements. At the same time, as a third-party transponder application, it must be independent of the existing on-board transponder equipment
