Abstract

The invention provides a method for device fault intelligent diagnosis and number-cancelling processing of LKJ. The method includes the steps of reading and parsing a fault condition configuration file, and parsing and writing the judgment criterion of various fault types into a fault condition object array; reading and parsing a dump LKJ running file based on a protocol, and parsing and writing each record information item in the LKJ running file into a memory data table; according to the fault judgment condition in the fault condition object array, traversing and statistically analyzing the record information in the memory data table to determine whether or not the fault condition is satisfied; if yes, carrying out a fault processing procedure; if the analysis does not find a fault, extracting the locomotive information in the LKJ running file, and querying whether or not the non-number-cancelling fault information about the locomotive extracted in the LKJ running file exists in a locomotive fault information table; if the non-number-cancelling record information is found, setting the state of fault processing to be a number-cancelling state, and finishing the procedure; if the record information of satisfying the condition is not found, finishing the procedure.

Description

technical field [0001] The invention relates to the field of information management of a train operation monitoring system (hereinafter referred to as LKJ), in particular to a method for analyzing and processing failures of locomotive LKJ equipment. Background technique [0002] The train operation monitoring system (LKJ) provides an important guarantee for the safety of locomotives. The operation quality of LKJ equipment is the basis of operation safety. Pay attention to. [0003] At present, the Railway Bureau mainly uses the ground processing software to analyze the LKJ operation record file, analyze the locomotive operation record file according to the protocol, and then open and view it through the software, manually query the locomotive operation record information to analyze the locomotive equipment failure, and notify the maintenance personnel after the analysis finds the fault information Carry out equipment replacement and maintenance, and the repaired equipment w...
