Method and device for detecting serpentine instability of train bogie, system and storage medium

Abstract

The application relates to a method and device for detecting the serpentine instability of a train bogie, a system and a storage medium. The method for detecting the serpentine instability of the train bogie comprises the steps of conducting characteristic analysis on real-time collected lateral vibration data of the bogie, and inputting obtained characteristic data into an instability classification model to obtain an instability detection result. Statistical mining and modeling analysis are conducted on the lateral vibration data of the train bogie on the basis of two dimensions of the timedomain and the frequency domain, the data characteristics for characterizing the serpentine instability of the bogie and the distribution condition of the data characteristics can be extracted from different angles, and therefore diagnosis and judgment can be conducted through the instability classification model. The classification model obtained based on historical data training is adopted for instability judgment, the detection standards of the method are more objective, the influence of human subjective factors can be reduced, and the accuracy of instability judgment is increased. On thisbasis, whether or not the serpentine instability phenomenon happens to the train bogie can be monitored and analyzed in real time, and a driver is timely reminded to take measures such as speed reduction to ensure safe running of a train.

Description

technical field [0001] The present application relates to the technical field of rail transit, in particular to a method, device, system and storage medium for detecting serpentine instability of a train bogie. Background technique [0002] Railway is the main artery of transportation. In recent years, my country's railway industry has developed rapidly. With the continuous improvement of train speed, train operation safety is facing huge challenges. Due to the vast territory of our country and the large differences in the working conditions of different lines, the vibration acceleration of the train bogie presents the characteristics of diversity, randomness, and rich frequency bands that vary with the speed, and its serpentine motion is one of the important factors that affect the safety of trains. . [0003] In the process of implementation, the inventors found at least the following problems in the traditional technology: the detection accuracy of the serpentine instabi...
