A method for early warning analysis of high-power locomotive faults

Abstract

The invention relates to a high-power locomotive fault early-warning analysis method, which is characterized in that an on-board microcomputer control system of a high-power locomotive is provided with a USB interface for external dump, dumped files comprise locomotive event recording files and locomotive diagnosis recording files, the files are dumped to a ground detector by adopting hexadecimal byte codes and ZIP format compression packets, and the files are parsed by the detector and stored to a relational database so as to form data-oriented diagnosis recording data; and then analysis and processing are performed by a locomotive early-warning analysis system according to determined principles. According to the invention, on-board data files are parsed and stored to the database through a ground data analysis system, thereby realizing persistent storage of locomotive data. The ground data analysis system performs grade division on locomotive faults according to a corresponding relation between fault codes and fault grades, and carries out different maintenance processing according to different fault grades, thereby realizing an effect of maintenance guidance.

Description

technical field [0001] The invention relates to a method for early warning analysis of railway locomotive operation, in particular to analysis of on-board fault data of high-power locomotives and a method for early warning of the locomotive; it is mainly used for fault analysis and early warning of high-power locomotives. It belongs to the technical field of locomotive monitoring. Background technique [0002] At present, the existing domestic high-power locomotives all have on-board microcomputer control systems. The on-board microcomputer control system records the events and failures during the operation of the locomotive in detail, especially the detailed parameter information of each sensor of the locomotive when a failure occurs. However, the records of these information are mainly used for the analysis after the locomotive breaks down, and the data dump requires analysts to get on the train and use the U disk to dump, and copy the data files from the U disk to the co...

AI Technical Summary

Problems solved by technology

[0009] The purpose of the present invention is to address the existing problems of the lack of early warning analysis of existing high-power locomotives in fault analysis, and to propose a high-power locomotive fault early warning analysis method. This kind of high-power locomotive fault early warning analysis method can , to predict the type and degree of locomotive failure in advance, so that it can be predicted in advance whether there is a hidden trouble in the operation of a high-power locomotive, what kind of hidden trouble, and a further system life analysis can be done
