Abstract

The application relates to a train bearing fault early warning method, device and system and a storage medium. According to the train bearing fault early warning method, axle temperature data, collected by a ground system, of a train are calculated; calculated characteristic data are inputted into an early warning model to obtain an early warning result, wherein the early warning model is a grading model that is established by selecting data of a period of time before the bearing fault occurrence moment and based on historical shaft temperature data; and the feature data are compared with eachthreshold in the early warning model to obtain a corresponding early warning result. On the basis of the bearing fault grading early warning mode, the historical axle temperature data of a train canbe effectively utilized; and early warning is carried out at the early stage of bearing abnormity to discover the abnormity and process the abnormity early, so that the occurrence of the bearing faultis prevented. Meanwhile, the normal state of the bearing is ensured; the abnormal occurrence in the driving process can be reduced; the normal driving is ensured; and the line congestion caused by accidents caused by vehicle bearings is reduced.

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...
