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 GSM-R network switching device and method for a locomotive station. On the basis of a standard CIR, a locomotive station device unit is added to realize the function of dual-G network access. The locomotive station device has two sets of GSM‑R voice units and GSM‑R data units, which can be connected to domestic GSM‑R networks and foreign GSM‑R networks respectively, so that one locomotive station can be connected to two GSM‑R networks Ability. This invention is applied to cross-border railway locomotives for the first time both at home and abroad, and develops a new mode for the application of cross-border railway locomotives in the future, which reduces the demand for locomotive installation space and can facilitate drivers and operators to adapt. It not only meets the needs of users, but also helps users control the investment cost of 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...
