The present application relates to a train bearing fault early warning method, device, system and storage medium. Among them, the train bearing fault early warning method calculates the axle temperature data of the train collected by the ground system, and inputs the calculated characteristic data into the early warning model to obtain the early warning result. The early warning model is a classification model based on historical shaft temperature data based on the data of a period of time before the bearing failure time. Comparing the feature data with the thresholds in the early warning model, the corresponding early warning results can be obtained. Based on the grading warning method of bearing faults, the historical axle temperature data of trains can be effectively used to give early warnings in the early stage of bearing abnormalities, so as to realize early detection and early treatment of abnormalities and prevent the occurrence of bearing faults; Abnormal occurrences in the process ensure normal driving and reduce line congestion caused by accidents caused by vehicle bearings.
Description
technical field [0001] The present application relates to the technical field of rail transit, in particular to a train bearing fault early warning method, device, system and storage medium. Background technique [0002] There are more than 6,000 freight or passenger locomotives in domestic circulation for many years, and the front-line maintenance of the corresponding vehicles is extremely difficult. The safe operation of the locomotive requires the normal operation of all parts of the locomotive, the daily maintenance of the locomotive, and the periodic abnormal monitoring of the corresponding vehicle components. Bearing is one of the most important components of a locomotive, and the safety status of the bearing plays an important role in the safe operation of the locomotive. The mechanical abnormality or electrical abnormality of the bearing will usually lead to drastic changes in the bearing temperature. Once a thermal shaft accident occurs, if no timely measures are t...
