Embodiment 1

[0082] See figure 1 , Which shows a flow chart of the vehicle-ground communication data processing method provided by this application, which may include the following steps:

[0083] Step S11: Obtain the original data of vehicle-ground communication.

[0084] In this embodiment, the original vehicle-ground communication data is the monitoring and detection data in the CTCS-3 level train control system, which can be specifically but not limited to: GSM-R interface monitoring data or dynamic detection data or network management system monitoring data or ATP Log data or RBC log data or DMS data.

[0085] Among them, the GSM-R interface monitoring data is the monitoring of the communication interface (such as the Abis interface, where the Abis interface is the communication interface between the BTS equipment and the BSC equipment) in the GSM-R network system (such as BTS, BSC, MSC, etc.) data.

[0086] The dynamic detection data is the dynamic detection data for multiple devices in the...

Embodiment 2

[0149] In this embodiment, in figure 1 On the basis of the vehicle-ground communication data processing method shown, another vehicle-ground communication data processing method is extended, please refer to Figure 5 , Can include the following steps:

[0150] Step S51: Obtain the original vehicle-ground communication data.

[0151] Step S52: According to the value of the vehicle-ground communication raw data obtained by the vehicle-ground communication, classify the vehicle-ground communication raw data to obtain a classification result, and the classification result is that the vehicle-ground communication raw data is normal or normal. The vehicle-to-ground communication raw data has potential failure risks or the vehicle-to-ground communication raw data is abnormal.

[0152] Step S53: Mark the original vehicle-ground communication data according to the classification result to obtain marked data.

[0153] The process shown in step S51 to step S53 is the same as figure 1 Step S11 an...

Abstract

The invention provides a train-ground communication data processing method and apparatus. The train-ground communication data processing method comprises the steps of obtaining train-ground communication original data; obtaining numerical values of the train-ground communication original data according to the train-ground communication originally, and classifying the train-ground communication original data to obtain a classified result; marking the train-ground communication original data according to the classified result to obtain a marked data; finding whether a fault data corresponding to the marked data exists in a knowledge base or not, wherein the fault data is a fault reason or a possibly-caused fault; if the fault data corresponding to the marked data exists in the knowledge base, outputting a first calculation result which at least comprises the marked data and the fault data corresponding to the marked data; and if the fault data corresponding to the marked data does not exist in the knowledge base, performing non-real-time analysis on the marked data to obtain a second calculation result, and outputting the second calculation result. According to the train-ground communication data processing method and apparatus, detection efficiency is improved by virtue of the mode, thereby eliminating faults in time and improving the reliability and safety of the train operation.

Description

Technical field [0001] This application relates to the field of communication, and in particular to a method and device for processing vehicle-ground communication data. Background technique [0002] At present, domestic high-speed railways with speeds of 300km / h and above use CTCS-3 train control system. In the CTCS-3 level train control system, the on-board equipment on the train performs two-way wireless communication with the ground trackside equipment and RBC through the GSM-R network. [0003] Among them, during the two-way wireless communication between the on-board equipment on the train and the ground trackside equipment and RBC through the GSM-R network, communication failures may occur. At present, after a communication failure occurs, maintenance personnel perform troubleshooting on each communication device one by one to find the source of the failure. The efficiency is low, and the failure source cannot be eliminated in time, which affects the reliability and safety ...
