Locomotive status messages checking and diagnosis recording method and device

Abstract

The invention provides a locomotive state information detection and diagnosis recording device, comprising a data collecting unit and a data processing unit; the data collecting unit is used for carry out real-time data communication with the on-board equipment of the locomotive and collecting the running data of the locomotive; the data processing unit is used for reading the data collected by the data collecting unit, obtains various events happened to the locomotive by carrying out classified logic judgment to the data according to different locomotive event types, writes all the events happened to the locomotive and corresponding parameters into a recording file and memorizes the file; meanwhile, the bidirectional transmission of the data between the locomotive and the ground can be realized by the wireless communication network. The invention also provides a locomotive state information detection and diagnosis recording method. The adoption of the device and the method of the invention realize the online diagnosis of the locomotive malfunction, record the running data of the locomotive objectively and practically, monitor the running state information of the locomotive in real time, and realize the bidirectional transmission of the data between the locomotive and the ground.

Description

technical field [0001] The invention relates to network control technology, in particular to a method and device for detecting and diagnosing record of locomotive state information. Background technique [0002] As a key component of railway transportation, the quality of locomotives' running status is related to the quality of the entire railway transportation system. During train operation, especially when locomotive failures or accidents occur, ground traffic dispatching and locomotive operation management departments are required to remotely provide drivers with technical support for troubleshooting based on the obtained locomotive operation detection information. At present, although some locomotive products have realized the online dynamic detection, recording and diagnosis processing functions of locomotive operation information and status information, they either have a single function, or the processed data is not comprehensive, so it can be said that they can fully...

AI Technical Summary

Problems solved by technology

[0007] (1) The running data of the locomotive cannot be recorded

[0008] Although the on-board data acquisition unit can send information to the ground in real time, limited by the amount of data transmission, it can only extract the necessary small-capacity information transmission from a large amount of information, and it is likely that some useful locomotive operating data will be ignored without record storage down, which greatly reduces the basis for ground system fault diagnosis

[0009] (2) No online fault diagnosis

[0010] The on-board data acquisition unit itself does not have an online diagnosis function, and all fault diagnosis can only be processed through the ground system, which reduces the response speed of fault diagnosis and increases the workload of the ground system

[0011] (3) It is impossible to monitor the running status information of all types of locomotives in real time

It can be seen from this that the information it collects is not comprehensive enough, it is not open to the on-board equipment of locomotives, and cannot meet the needs of various types of information transformation

[0013] (4) No redundant design is adopted

[0014] The basic characteristic of the locomotive on-board data acquisition unit is the high-speed processing of a large amount of data. Since no redundant design is adopted, once a failure occurs, the reliability and continuity of the data cannot be guaranteed.
