Locomotive fault data filtering method and device

Abstract

The embodiment of the invention provides a locomotive fault data filtering method and device. The method comprises the steps of acquiring all fault data with state information labels and fault position labels are acquired; marking the fault data except the candidate state information, and storing the fault data after filtering the marked data into a fault database; if a secondary filtering optioninput through the human-computer interface is received, correspondingly filtering all the fault data in the database, and displaying the fault data, wherein the state in the state information comprises running states of a driving device, a shunting device, a warehouse-out device, a warehouse-in device and a vehicle-mounted device, and the secondary filtering option comprises a position option. Bymarking the fault data except the candidate state information, only the key fault data is pushed, so that post-event fault analysis is facilitated, invalid fault cleaning is realized, emergency command is facilitated, and the emergency disposal efficiency is improved. And moreover, the user can configure the filtering condition by himself / herself through the secondary filtering option, so that different users can conveniently use as required.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a locomotive fault data filtering method and device. Background technique [0002] Locomotive faults mainly refer to the fault data generated or monitored by the on-board TCMS microcomputer and 6A systems of locomotives in transit. During operation, various systems of the locomotive will generate a large amount of fault data due to various reasons. Among the many fault data, only a small part of the faults affect safe driving, and most of the faults are faults or secondary fault data that do not affect safe driving. This kind of information not only cannot be used for driving guidance, but will cause interference and cause safety hazards. [0003] The China Locomotive Remote Monitoring and Diagnosis System (CMD) uses on-board equipment to collect various status and fault data of the locomotive, and uses 4G / 5G wireless communication technology to send back to the ground sys...

AI Technical Summary

Problems solved by technology

[0004] The current system’s method of handling faults issued by locomotives is mainly to screen users on the ground by inputting corresponding conditions in the system, and then analyze and deal with them according to the corresponding fault handling process. The user’s operation process is more complicated, and at the same time, it is necessary to judge whether the fault is real and effective. affect efficiency

At the same time, there are too many invalid faults and secondary faults issued by the locomotives in the system, which have a certain impact on the user's analysis of faults, and cannot realize the expected vision of the system
