Description

Technical Field

[0001] The invention relates to the technical field of EMU train network debugging, and in particular to a 160km urban EMU MVB vehicle bus debugging tool. Background Art

[0002] At present, when networking and debugging the MVB vehicle bus, the resistance of the MVB bus is often measured to determine whether the terminal resistance of the MVB connector plug of the line is cut incorrectly and whether the wiring of A and B is connected incorrectly. When measuring, the terminal resistance of the MVB backbone network should be 120 ohms and the resistance of the entire ring network should be 60 ohms; for the male DB9 plug, when using a multimeter to measure the terminal resistance of pins 1 and 2 or pins 4 and 5, the test lead is easy to slip when contacting the pin, and the test lead is also easy to touch non-measurement pins or edge metal shells, which is easy to cause inaccurate measurement and is more challenging for the measurement personnel; for the female DB9 plug, when using a multimeter to measure the terminal resistance of pins 1 and 2 or pins 4 and 5, the test lead cannot directly contact the plug pin, and it is necessary to temporarily find a bare wire and insert it into the hole, and then measure the resistance between the two bare wires. During measurement, the bare wire is easy to rotate, the test lead is easy to make false contact, and the resistance reading is unstable.

[0003] Network debugging restricts many important subsequent debugging items in the entire train debugging process and is the immediate predecessor of many important debugging tasks. The success of its debugging directly affects the debugging progress of the entire train, and MVB bus debugging is the top priority of network debugging.
