Embodiment

[0027] The vehicle failure recording method of the present embodiment includes the following steps:

[0028] The first step is to read the configuration file, and clean up the data record file list according to the data record file; the configuration file, data record file, and data record file list are all stored in the mobile memory; the configuration file contains fault variables and environment variables that need to be recorded, Correspondence between each fault variable and environment variable, as well as various configuration parameters; the data record file stores the recorded fault variable data and environment variable data; the list of data record files is the list of data record files existing in the current mobile memory; go to second step;

[0029] Among them, the specific process of clearing the list of data record files is as follows: search the data record files recorded in the list of data record files in the mobile memory one by one, if there is a correspon...

Abstract

The invention relates to a vehicle failure recording method. The vehicle failure recording method includes steps of initialization, environment variable monitoring, and failure variable and environment variable recording synchronous with failure occurrence, wherein the failure variable and environment variable recording lasts until failure disappears. The vehicle failure recording method can record key environmental data while recording the failure, can assist maintenance personnel in easily completing judgment of failure reasons, and reduces working strength of the maintenance personnel.

Description

technical field [0001] The invention relates to a vehicle failure recording method, which is suitable for rail vehicles. Background technique [0002] For a long time, in the field of rail transit vehicles, fault records usually only record information about the fault itself, such as fault occurrence time, disappearance time, fault description, fault level, vehicle speed when the fault occurs or disappears, etc. However, such information cannot well assist the maintenance personnel in judging the cause of the failure. Train maintenance personnel still rely on experience to judge the cause of failure to a large extent, which has caused a lot of trouble to the maintenance personnel's work. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing problems in the prior art and provide a vehicle failure recording method, which can assist maintenance personnel to easily complete the judgment of the cause of the f...
