Mutual-induction type automatic online reliability diagnosing and repairing system for long-distance multi-node train line and use method thereof

Abstract

The invention discloses a mutual-induction type automatic online reliability diagnosing and repairing system for a long-distance multi-node train line and a use method thereof. The system comprises a master machine and a slave machine, wherein the master machine comprises an electric grinding part which is connected with a detected line pair in parallel; the slave machine comprises a slave end voltage detecting part and a slave end auxiliary control part; and the slave end voltage detecting part is connected with the detected line pair in parallel and is connected with the electric grinding part and the slave end auxiliary control part by trigger control lines. Compared with the prior art, the system disclosed by the invention has the following benefits: 1, real-time online detection and automatic grinding of the circuit reliability of a long-distance multi-node train line are realized, influence of high-frequency detection and circuit interruption operation on the usability of the circuit is avoided, and the overhauling and disassembled maintenance of equipment parts are avoided, therefore, the repairing efficiency and the reliability are greatly improved and the loss rate and cost are reduced; and 2, the whole structure is simple and compact and the operation is convenient and easy.

Description

technical field [0001] The invention relates to an on-line diagnosis and repair system for train line reliability and its use method, belonging to the technical field of electrical automation, in particular to long-distance multi-node train line reliability involving electrical switches, relays and other contacts and conductive contact surfaces of electrical connectors. A sexual mutual inductance automatic online diagnosis and repair system and its application method. Background technique [0002] In the field of electrical automation, various switching components are widely used, which has an important impact on the reliability of many key circuits that operate continuously online. As we all know, a train is generally composed of multiple carriages, and some logic control signal lines and signal control ring lines need to run through the entire train. Therefore, multiple segmented connectors need to be installed on the train line to facilitate train disassembly and line mai...

AI Technical Summary

Problems solved by technology

In the existing technology, the traditional repair method is to disassemble the switch element and disassemble it, take out the pin of the contact or connector, and manually grind the conductive contact surface, but for some fully sealed switchgear, it can only be scrapped replace

This traditional grinding method needs to disassemble and reassemble the switch elements, which is complicated and labor-intensive, and it is difficult to ensure that the fit clearance after reassembly can be restored to the original best state; on the other hand, grinding will also damage the contact copper surface There is additional wear and tear, and usually the contacts need to be scrapped after only one or two grinding repairs; at the same time, contact grinding has higher technical requirements for operators
