Description

technical field [0001] The invention belongs to the technical field of rail transit, and relates to a debugging technology of rail vehicle electronic equipment, in particular to a debugging system and a debugging method for rail vehicle electronic equipment. Background technique [0002] With the rapid development of rail transit technology, people choose more subways, EMUs and high-speed rail for travel. While rail transit brings convenience to people, it also puts forward higher requirements for various electronic equipment of rail vehicles. Before the vehicle is operated with passengers, it is necessary to fully perform performance debugging on each electronic device to ensure its reliability and safety during the actual operation of the rail vehicle. [0003] Rail vehicles have a lot of electronic equipment, and usually electronic equipment has complex internal data. During the debugging process, it is often necessary to obtain internal data to determine whether the elec...
