Integrated BTM antenna device and communication method thereof

Abstract

The invention belongs to the technical field of train operation control, and particularly relates to an integrated BTM antenna device and a communication method thereof. Wherein the device is provided with a first cavity and a second cavity which are integrally arranged in the same shell, and the first cavity and the second cavity are respectively used for installing a BTM host and a BTM antenna; wherein the BTM antenna arranged in the second cavity comprises an antenna plate and a WiFi module; the BTM host arranged in the first cavity is of a double-layer structure and comprises a communication board, a recording board and a decoding board which are arranged on the first layer, and a power board, a sending board and a receiving board which are arranged on the second layer. According to the integrated BTM antenna device, the BTM host and the BTM antenna are integrated in the same shell, the installation space in a vehicle-mounted cabinet can be saved, the integrated BTM antenna device communicates with a vehicle-mounted signal system through a CAN communication cable, and the problem that train electricity interferes with a BTM radio frequency antenna is thoroughly solved.

Description

technical field [0001] The invention belongs to the technical field of train operation control, in particular to an integrated BTM antenna device and a communication method thereof. Background technique [0002] BTM (Balise Transmission Module, balise information receiving unit) equipment is an important part of the balise system, mainly used to receive the balise information sent by the ground balise, process the balise information to obtain the balise user message, And report to the train operation control system, which is convenient for the train operation control system to control the train operation. refer to figure 1 As shown, the BTM device is mainly composed of a host and an antenna unit. At present, the BTM host is installed in the vehicle cabinet in the form of a 19’ box, the BTM antenna is installed on the bottom of the vehicle through a metal bracket, the BTM host and the antenna communicate through a coaxial communication cable, and the BTM host communicates w...

AI Technical Summary

Problems solved by technology

[0003] The BTM host is installed in the vehicle-mounted cabinet in the form of a 19' plug-in box. On the one hand, it occupies the limited installation space of the vehicle-mounted cabinet and affects the flexibility of the vehicle-mounted cabinet; Shaft communication cables transmit analog signals susceptible to electrical interference from trains
