Abstract

The invention discloses a failure recognition method and system based on neural network self-learning. The method comprises the steps that (1), various set monitoring quantities of track traffic equipment are monitored and collected, and the collected monitoring data are converted into sample data applicable to training the neural network; (2), the sample data are classified according to the types of failures, and a sample data set corresponding to each type of failure is obtained; (3), one neural network is designed for each type of failure, then the sample data sets of the failures are used for training, and a recognition model of each type of failure is obtained; (4), the recognition models of all the types of failures are fused to be one neutral network, and failure recognition is carried out on the monitoring data collected in real time. The method can calmly cope with complex equipment failures and train operation accidents.

Description

technical field [0001] The invention provides a fault identification method and system based on neural network self-learning, which relates to technical fields such as railway signal data, railway communication data, railway knowledge data, system alarm data, machine learning, neural network, self-learning, expert system, etc. In order to solve the problems faced by the data analysis of rail transit monitoring data. Background technique [0002] In order to improve the modern maintenance level of my country's railway signal system equipment, since the 1990s, TJWX-I and TJWX-2000 have been independently developed and continuously upgraded signal centralized monitoring CSM systems. 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 ...
