TECHNICAL FIELD
[0001] The present application relates to the technical field of rail vehicle line detection, and in particular to an automatic line fault detection system and method for a train carriage. BACKGROUND
[0002] With the rapid development of modern industry and transportation, the line systems in various equipment and vehicles are increasingly complex and precise. Taking vehicles as an example, in the long-term operation process, the internal cables will not only gradually reduce the performance due to natural wear and tear, but also any slight error in production and manufacturing, line laying, construction and installation, and daily operation may cause hidden faults. Common line fault types include open circuit, short circuit, and abnormal grounding of the core, etc. Once these faults occur, they will seriously affect the normal operation of the equipment and even cause safety accidents.
[0003] Open circuit fault is manifested as the internal conductor of a single or multiple cables being broken, causing the transmission of electric energy to be blocked. Even if the insulation performance of the line is within the qualified range, the terminal voltage and load capacity will be greatly reduced, and the circuit will be in an open circuit state. Short circuit fault is caused by damage to the insulation layer between the lines or the line and the ground. When the fault impedance is lower than a certain threshold of the cable wave impedance, an abnormal current loop is formed, which damages the line and equipment. The abnormal grounding of the core fault is often caused by insulation layer aging and damage, mechanical force damage, etc., which easily interferes with the normal operation of the system and threatens the safety of personnel and equipment, so the line needs to be detected at regular intervals.
