Problems solved by technology

However, after the ground equipment sends out the message information, it is impossible to confirm whether the vehicle can normally execute according to the message information, and the vehicle cannot confirm whether the message information is normally sent by the ground equipment (there may be equipment failure in the middle)
In the existing system, the equipment information on both sides can only be monitored separately through the ground or vehicles, and closed-loop monitoring cannot be realized

Embodiment 1

[0041] Embodiment 1, during the operation of the vehicle, the communication quality between the vehicle and the ground equipment is not good, and the log of the Radio Blocking Center (RBC) is checked in the ground equipment, and the log records are as follows:

[0042] serial number time log type event ID 8259 2018-01-23 20:05:17 stp data to train 0 8261 2018-01-23 20:05:18 stp disconnect ind 0 8283 2018-01-23 20:05:30 stpconnectind 0

[0043] It can be seen from the above table that RBC sent a disconnection frame to the link layer at 20:05:18.

[0044] For the specific reason for finding the disconnected frame, the information data in the RBC log and the record data at the train equipment end are extracted according to the response time between the train and the RBC. The obtained RBC record information and train protection system record information are organized in the following table:

[0045]

[0046]The train sent a message t...

Abstract

The invention relates to an analysis method of an intelligent fault analysis platform for a railway signal system. The analysis method comprises the following steps: recording historical fault features, forming a diagnosis feature sequence of a fault according to the historical fault features, diagnosing one or more faults meeting specific conditions in the diagnosis feature sequence according tothe feature sequence, obtaining vehicle information data and ground data according to the specific conditions, automatically analyzing the vehicle information data and the ground information data, anddiscovering the source of the abnormal information data. According to the analysis method, the vehicle data and the ground data can be automatically extracted according to the fault features, and a user is helped to quickly determine a fault reason and a fault location.

Description

technical field [0001] The invention relates to the field of railway signal failure analysis, in particular to an analysis method for a railway signal system failure intelligent analysis platform. Background technique [0002] The high-speed and safe operation of railway trains requires not only good railway infrastructure and train status, but also information transmission of railway signaling systems and information transmission of train operations. my country's existing track signal system adopts the railway integrated dispatching mobile communication system (GSM-R), including vehicle-mounted subsystems, ground subsystems, and other management subsystems such as GSM-R networks. Each subsystem will be divided into multiple modules to collect various data of track and train operation, which can realize real-time monitoring of track conditions and driving status, ensure the safety of train operation, and improve the efficiency of track use. [0003] However, the monitoring ...
