Title:
TRAIN-MOUNTED PHM DEVICE, AND HIGH-SPEED TRAIN
Document Type and Number:
WIPO Patent Application WO/2020/029450
Kind Code:
A1
Abstract:
A train-mounted PHM device, which uses an information acquisition apparatus (20) to acquire device operating data of a train traction motor (10), and performs comparative analysis on the device operating data and PHM standard data (comprising operating data under a full life cycle of the device) stored in a train PHM diagnostic apparatus (30) to determine an operating state of the train traction motor (10), thereby predicting, according to the operating state, whether a fault may occur in a next period of time. By using the train-mounted PHM device, in combination with the comparative analysis between actual operating data of a device and PHM standard data, an impending fault is found and processed before the fault happens, so that the security of a high-speed train is further improved. Also provided is a high-speed train having the train-mounted PHM device.
