Problems solved by technology

[0006] In order to urgently solve the problem of cross-border railway train communication and meet the cross-border needs of EMUs, freight trains, etc., in order to solve the problem that cross-border railway trains need to connect to the domestic GSM-R network during domestic operation, and need to connect to the GSM-R network during foreign operation GSM-R network in foreign countries, and the locomotive has no extra space to install two sets of locomotive stations. On the basis of the existing CIR, adding a locomotive station G network switching device can conveniently realize two GSM-R networks access to meet the requirements of railway transportation, so that it has dual G network functions and can meet the operation requirements of cross-border railways

Abstract

The invention relates to a locomotive station GSM-R network switching device and a locomotive station GSM-R network switching method, which are used for realizing a double-G network access function by adding a locomotive station device unit on the basis of a standard CIR. The locomotive station device is provided with two groups of GSM-R voice units and GSM-R data units, and the two groups of GSM-R voice units and GSM-R data units can be respectively accessed to a domestic GSM-R network and a foreign GSM-R network, so that one locomotive station has the capability of accessing two GSM-R networks. The cross-border locomotive platform is applied to the cross-border locomotive for the first time in China and international, a new mode is developed for application of the cross-border locomotive platform in the future, the requirement for locomotive installation space is reduced, and a driver and an operator can conveniently adapt to the cross-border locomotive platform. The requirements of the user are met, and the user is helped to control the input cost of the equipment.

Description

technical field [0001] The invention relates to a railway communication locomotive station device, in particular to a GSM-R network switching device and method for a locomotive station used by cross-border trains. Background technique [0002] Traditional locomotive integrated wireless communication equipment CIR, (China Railway Corporation Enterprise Standard: Q / CR 651.1-2018 Locomotive Integrated Wireless Communication Equipment Part 1: Technical Conditions) see Figure 11 , the host includes A subrack and B subrack, and the A subrack includes a GSM-R voice unit and a GSM-R data unit, and only has the function of accessing a group of GSM-R networks. [0003] (Invention patent number: CN 106059875) (hereinafter referred to as: CIR), the host only has a group of GSM-R network communication modules, which are GSM-R voice unit and GSM-R data unit, and only has access to a group of GSM - Function of the R network. [0004] According to the current operating requirements of hig...
