Cab integrated radio communication equipment

Abstract

The invention discloses a piece of cab integrated radio communication equipment comprising a CAN interface conversion unit 1, a GSM-R voice unit connected with the CAN interface conversion unit 1, a main control unit, a satellite positioning unit, a spare control unit, a CAN interface conversion unit 2, a GSM-R data unit connected with the CAN interface conversion unit 2, a 400MHz / 450MHz communication unit, an LBJ communication unit, a record unit, a wireless broadband unit, a power supply unit, a power bus, a CAN bus 1, and a CAN bus 2. The main control unit is connected with the CAN interface conversion unit 1, the satellite positioning unit, the spare control unit, an exchange interface unit, the CAN interface conversion unit 2, the 400MHz / 450MHz communication unit, the LBJ communication unit and the record unit through the CAN bus 1 and the CAN bus 2, and is connected with the spare control unit, the exchange interface unit, the record unit and the wireless broadband unit through an LAN cable. The exchange interface unit is connected with a plurality of MMI terminals. The equipment has the advantages of high reliability, high security and high flexibility, can achieve a function of remote software and database upgrading, and can meet the requirement of a 400MHz band.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a locomotive integrated wireless communication device. Background technique [0002] At present, CIR (Cab Integrated Radio communication equipment, locomotive integrated wireless communication equipment) has been applied on the national railways for more than 8 years, and it is playing an increasingly important role in the daily transportation command of the railway. [0003] Each functional unit of the CIR equipment mainframe adopts a modular design, and the equipment is composed of a mainframe equipment, an operation display terminal (MMI), a handset, a loudspeaker, and a printing terminal. The functional units of the device host include power supply unit (including power supply and battery subunit), control unit, GSM-R voice communication unit, GSM-R data communication unit, 450MHz communication unit, LBJ unit, interface unit, wireless broadband data communication unit, ...

AI Technical Summary

Problems solved by technology

[0008] At present, when key functional units such as the GSM-R voice communication unit and GSM-R data communication unit on the CIR host are damaged during use, due to the absence of redundant design, the equipment cannot be used normally, affecting train operation

[0009] 2. Compatibility issues

[0010] The physical dimensions, electrical characteristics, communication protocols, and cables of the functional units of CIR equipment from different manufacturers are inconsistent, resulting in the inability to interconnect and interoperate between equipment from different manufacturers.

[0011] 3. Flexibility issues

[0012] 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

[0013] 4. The equipment has no identification, which is not convenient for maintenance and management

[0014] At present, the CIR complete machine and functional units do not have a uniquely identified serial number, resulting in the inability to trace the configuration status of the complete machine and functional units, increasing the difficulty of maintenance

[0015] 5. The problem of not being able to meet the 400MHz frequency band

However, the current CIR equipment cannot meet the requirements of the 400MHz frequency band

[0017] 6. There is no remote upgrade software and database function

[0018] At present, CIR equipment does not have the function of remotely upgrading software and database, and can only upgrade software and database manually on site, which is a waste of labor and is not convenient for timely upgrading

[0019] 7. The handset is inconvenient to use

The buttons on the current handset are too small, which often leads to mispressing
