example 1
[0071] This example performs data processing on the line direction data monitored by a CSM.
[0072] To collect the data of the line direction information of the train control center, the input data is:
[0073] 1) Line direction information sent by the train control center of the station;
[0074] 2) The line direction information sent by the train control center of the adjacent station.
[0075] For the collected data, first establish the relationship between the data, which is:
[0076] ① One shot after another -> Normal
[0077] ② One send one receive -> Normal
[0078] ③Both stations are sending->abnormal
[0079] ④ Both stations are closed -> Abnormal
[0080] ⑤ Invalid direction -> exception
[0081] Then the comparative analysis model of normal state and abnormal state is established as follows:
[0082] Normal state: one send and one send, one send and one receive
[0083] Abnormal state: Both stations are sending, both stations are receiving, and the directio...
example 2
[0090] This example compares the consistency between a CTC (Centralized Command and Control System for Train Dispatching) and the temporary speed limit state of the train control center.
[0091] First collect the temporary speed limit status data of CTC and train control center, the input data is:
[0092] 1) CTC temporary speed limit state;
[0093] 2) Temporary speed limit status of the train control center.
[0094] For the collected data, first establish the relationship between the data, which is:
[0095] ①Temporary speed limit state of train control center is more than CTC->abnormal
[0096] ②Temporary speed limit status of train control center is equal to CTC->normal
[0097] ③Temporary speed limit state of train control center is less than CTC->abnormal
[0098] Then the comparative analysis model of normal state and abnormal state is established as follows:
[0099] Normal state: the temporary speed limit state of the train control center is equal to CTC

Abstract
The present invention relates to a rail traffic real-time fault diagnosis method based on data comparative analysis and a rail traffic real-time fault diagnosis system based on data comparative analysis. The method comprises the steps of (1) collecting the historical monitoring data and real-time monitoring data of rail traffic signal equipment, (2) according to the correlation relationship between the parameters of the historical monitoring data, obtaining a comparative analysis model of a normal state and a fault state, (3) according to the comparative analysis model of the fault state, generating the classification model of fault through classifier training, (4) for the real-time monitoring data, judging the normal state or abnormal state of equipment operation through the comparative analysis model, and carrying out fault alarming if the state if the abnormal state, (5) for the data of the abnormal state, carrying out fault diagnosis and classification through a fault analysis model, and outputting a fault diagnosis result. According to the method and the system, the fault of the equipment is diagnosed through classification and comparative analysis methods, and the problems of heavy workload, low efficiency and high risk in the artificial diagnosis of a railway signaling system failure are effectively solved.
Description
technical field [0001] The invention belongs to the technical field of rail transit information, and in particular relates to a method and system for real-time fault diagnosis of rail transit based on data comparison and analysis. Background technique [0002] In order to improve the modern maintenance level of my country's railway signaling system equipment, since the 1990s, my country has independently developed TJWX-I and TJWX-2000 signal centralized monitoring CSM systems that are constantly being upgraded. At present, most of the stations have adopted computer monitoring system to realize the real-time monitoring of the signal equipment status of the station, and by monitoring and recording the main operating status of the signal equipment, it provides a basis for the electric department to grasp the current status of the equipment and conduct accident analysis. basis played an important role. Moreover, for urban rail transit signal equipment, the centralized monitorin...
