Method for degradation control of GSM-R (Global System for Mobile Communications-Railway) application service function of CIR (Cab Integrated Radio communication equipment)

Abstract

The invention discloses a method for degradation control of a GSM-R (Global System for Mobile Communications-Railway) application service function of CIR (Cab Integrated Radio communication equipment). The method is a redundancy project for GSM-R units; the existing module resources can be fully utilized without adding a new unit, so that the reliability of a CIR communication system is enhanced, and furthermore, when the single module has a fault, the fault can be detected intelligently and a spare unit is adopted to replace the fault single module to work, so that the CIR works normally. According to the method, the unnecessary shutdown phenomenon caused by the GSM-R units can be avoided and all kinds of maintenance work brought by module replacement can be reduced.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a method for controlling the degradation of GSM-R application service functions applicable to CIR equipment. Background technique [0002] At present, each functional unit of the train CIR (Cab Integrated Radio communication equipment) locomotive integrated wireless communication equipment host adopts a modular design. [0003] The current defects of the GSM-R module on the CIR: [0004] 1. Reliability issues [0005] At present, the GSM-R voice communication unit and GSM-R data communication unit on the CIR mainframe are inspected before driving out of the warehouse. If there is no problem in the inspection, they can be used. It is unavoidable that the module is good during the warehouse inspection, and it is damaged during use. question. [0006] Although the host is designed in a modular manner, if the GSM-R voice communication unit and GSM-R data communication unit fa...

AI Technical Summary

Problems solved by technology

[0005] At present, the GSM-R voice communication unit and GSM-R data communication unit on the CIR mainframe are inspected before driving out of the warehouse. If there is no problem in the inspection, they can be used. It is unavoidable that the module is good during the warehouse inspection, and it is damaged during use. question

[0006] Although the host is designed in a modular manner, if the GSM-R voice communication unit and GSM-R data communication unit fail, they can be easily disassembled and replaced with new modules. human physical loss

[0007] 2. Flexibility issues

[0008] The current GSM-R voice communication unit and GSM-R data communication unit only have a single function, that is, the GSM-R voice communication unit is only used for voice, and the GSM-R data communication unit is only used for data. Once one of the modules fails, G The network function cannot be used

And there is only one way to deal with the fault, which is to stop and replace the current faulty module, which lacks flexibility
