Abstract

The invention discloses an early warning method and device for an axle temperature fault of a vehicle bearing. The method comprises steps of working data of a vehicle in the current running process being obtained, and the working data being data related to the bearing temperature of the vehicle; analyzing the working data by adopting a regression prediction model, and predicting to obtain the bearing temperature of the vehicle in different time periods in the subsequent operation process; and based on the predicted bearing temperatures of the vehicle in different time periods in the subsequentoperation process, determining whether the bearing of the vehicle has a fault in the subsequent corresponding time period. According to the method, a problem that the early warning effect on the axletemperature fault of the vehicle bearing is poor in the related technology is solved.

Description

technical field [0001] The present application relates to the technical field of train safety, in particular, to an early warning method and device for axle temperature faults of vehicle bearings. Background technique [0002] With the official application and gradual improvement of the PHM system of EMUs, the safety requirements for train operation are getting higher and higher, and bearings are key components to ensure the safe operation of high-speed trains. The service environment is harsh, and it is easy to cause wear, peeling, cracks and other failures , which poses a huge threat to the safety of high-speed train operation, so it is necessary to monitor the operating status of the bearings. At present, high-speed trains mainly monitor the bearing temperature and issue alarms based on the set threshold. This method can effectively avoid serious safety accidents caused by hot shafts and burning shafts. However, once the alarm occurs, it will lead to vehicle operation acc...
