Problems solved by technology

However, at present, there is no system in the world that truly monitors the running status of rail vehicles in real time. Due to this reason, unnecessary delays and closures of rail transit have been caused, affecting the normal operation of rail transit, and causing unnecessary waste of financial resources, material resources and manpower. loss, so it is urgent to monitor the status of the train in real time throughout the rail transit

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0026] A method for real-time processing of mixed heterogeneous data information of embedded vehicle operating conditions, the main steps of the method are as follows:

[0027] 1) Identification of dynamic working condition data faults

[0028] Most of the track condition data failures are caused by detector failures or transmission line failures, so they can be divided into two categories: missing data and erroneous data.

[0029] (1) Identification of missing data

[0030] The fixed working condition monitors collect data according to a certain time interval, but in actual situations, the scanning frequency of the working condition monitor is not fixed, the failure of the transmission line and other reasons will make the collected data unable to strictly follow the When uploading at a specified time interval, data loss often occurs in a cer...

Abstract

The invention discloses a method for processing embedded vehicle working condition hybrid heterogeneous data information in real time. Since running data of a electromechanical device for a rail transit vehicle belongs to hybrid heterogeneous data, rail transit vehicle monitoring data acquired by a vehicle-mounted embedded data acquisition device can be detected in real time, and through data isomorphism, data filtering and information extraction, the failure level is evaluated by performing a certain calculation so as to classify accidents into four classes. Data is transmitted to different users according to priority levels of different classified accidents and can be used as a decision basis for driving and train monitoring of a driver.

Description

technical field [0001] The invention belongs to the field of rail transit vehicle working condition monitoring, and in particular relates to a novel heterogeneous data processing method supporting multi-equipment monitoring of trains. Background technique [0002] With the continuous development of cities and the rapid progress of society, rail transit has entered a stage of comprehensive development. In the entire rail transit system, the vehicle is an important and key component, which undertakes the important task of transporting a large number of passengers. Its operation and safety conditions directly affect the operation and safety of the entire rail line. The speed of the train is getting faster, the structure is more and more complex, the function is getting more and more perfect, and the degree of automation is getting higher and higher, which puts forward higher requirements for the reliability and safety of the train. However, at present, there is no system in th...
