Description

Technical Field

[0001] This utility model relates to the field of EMU network debugging technology, specifically to a rapid fault location and testing device for EMU networks. Background Technology

[0002] The trainset consists of two units, with each unit comprising four cars. The unit level and the vehicle level both utilize the MVB-EMD bus. All devices within the network, as well as third-party devices, are connected to the MVB-EMD bus. Each unit is an independent MVB network, with bus management, redundancy, and switching mechanisms within each network. The trainset's MVB lines possess a certain degree of self-diagnostic capability, reporting fault information on the trainset's HMI screen.

[0003] However, when a fault occurs in the A or B path of the existing EMU MVB, it will only report the fault in the A or B path of a certain unit's MVB. The fault point can only be located in the EMU unit, but not in the specific carriage or equipment. When the fault is reported continuously, it can take several hours to search carriage by carriage. However, when the fault is reported in a flash, it can only be monitored by trying to capture packets with an MVB network detector, which results in low fault diagnosis efficiency.

[0004] In view of the above-mentioned defects, the creator of this utility model has finally obtained this utility model after a long period of research and practice. Utility Model Content
