Description

Technical Field

[0001] The utility model belongs to the technical field of Ethernet monitoring, in particular to an online monitoring device for a train Ethernet physical layer. Background Art

[0002] Ethernet is a computer local area network technology that is also widely used on trains. Sometimes, there are many sudden network failures during train operation. However, most of them return to normal and cannot be located during static maintenance after returning to the depot.

[0003] When problems occur in train network communication on the market, the indirect evidence obtained by the currently commonly used indirect testing methods at the software level, such as the SNMP protocol, often points to multiple problem objects, which cannot meet the needs of users and OEMs to quickly and effectively clarify responsibilities. After the train network was upgraded to the Ethernet standard, the frequency of Ethernet signals increased significantly, and the confidence of the test results of the previously commonly used bus test equipment (for example, oscilloscopes) decreased. It is easy to cause network communication abnormalities due to measurement, and it is no longer suitable for on-site train testing. Utility Model Content

[0009] Furthermore, the button A, button B and button C are located below the indicator light area, button A and button B are reserved keys, and button C is a warning reset key.

[0010] Furthermore, the power interface A, power interface B, Ethernet interface A, Ethernet interface B and Ethernet interface C are arranged at equal distances in the horizontal direction, the power interface A is the default input 110V power supply, the power interface B is the default output 110V power supply, and the Ethernet interface C is used for configuration or management and data transmission and maintenance of the 100M Ethernet port.
