MVB protocol analyzer and working method thereof

Abstract

The invention discloses an MVB protocol analyzer and a working method thereof, and belongs to the field of train network communication. The MVB protocol analyzer provided by the invention comprises an ARM core, an FPGA core, an MVB interface and an LED touch screen, wherein the ARM core is in communication connection with the FPGA core, the FPGA core acquires data after receiving a data acquisition instruction sent by the ARM core,, and transmits the acquired data to the ARM core after decoding the acquired data, and stops data acquisition when receiving a data acquisition stopping instruction sent by the ARM core; the ARM core carries out data analysis on train MVB network data according to a TCN (Train Communication Network) protocol; the LED touch screen is connected with the ARM core, responsible for a function of man-machine interaction, and used for protocol analyzing software operation and relevant data display. The MVB protocol analyzer provided by the invention is convenient to carry, does not require to build a software running environment, not only can be used by debugging personnel before train delivery, but also can be used in running at delivery, and does not have high specialty requirements to operating personnel.

Description

Technical field [0001] The invention belongs to the train network communication field, and relates to an MVB protocol analyzer and a working method thereof, which is applied to a train communication network multifunctional vehicle bus. Background technique [0002] TCN-Train Communication Network (TCN-Train Communication Network) is a data communication network for the interconnection and transmission of control, monitoring and diagnosis information between railway train vehicles and the programmable equipment inside the vehicle. With the intelligentization of modern trains, the train communication network contains more information, such as status, control, fault diagnosis, passenger information, etc. How to analyze train operation data to find out the risks of train operation at an early stage and locate train defects , In order to ensure the safe operation of the train has become a key issue. [0003] As the current equipment used by the main engine factory for debugging trains ...

AI Technical Summary

Problems solved by technology

[0003] Since the equipment used by the main engine factory to debug trains currently adopts the combination of upper computer protocol analysis software and lower computer equipment, the variety of equipment and the installation of software for the debugging environment have brought a lot of inconvenience to the train debugging work.
