Embodiment Construction

[0040] It should be clear that the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0041] Such as figure 1 As shown, a subway operation and maintenance vehicle log analysis and early warning method, including:

[0042] Step S101: analyzing the downloaded diary file;

[0043] Step S102: Extract valid status data from the diary data obtained through analysis;

[0044] Step S103: Input the effective state data into the set behavior pattern for identification and matching calculation, so as to identify and predict the subway failure.

[0045] The behavior pattern can be selected according to actual needs, for example, it can be some existing behavior patterns such as behavior models obtained based on neural network training....

Abstract

The invention discloses a subway operation and maintenance vehicle-mounted log analysis and early warning method. The method comprises the steps that a downloaded log file is analyzed; Extracting effective state data in the log data obtained through analysis; And inputting the effective state data into a set behavior mode to carry out recognition and matching calculation, thereby carrying out recognition and prediction on the subway fault. According to the log analysis method and device, the effective state data in the log data obtained through analysis is extracted, the state data is automatically and accurately extracted, manual analysis and log data reading are not needed, automatic matching processing is carried out on the log information with non-uniform and irregular data formats, and the log analysis accuracy and integrity are improved.

Description

technical field [0001] The invention relates to the field of subway maintenance, in particular to a method for analysis and early warning of on-board logs for subway operation and maintenance. Background technique [0002] At present, the data analysis and maintenance of existing railway and subway vehicles mainly have the following problems: [0003] One is that the existing subway vehicle traffic information analysis mainly integrates the maintenance function into the vehicle operation control system, which causes difficulties for the independent operation and maintenance department. [0004] Second, for the log analysis of subway operation and maintenance, there are many types of data in the log text, and the data format is not standard. It is difficult for users and automatic analysis software to accurately and comprehensively extract status data. Contents of the invention [0005] The purpose of the present invention is to address the above problems and propose a met...
