Title:
TRACTION MOTOR BEARING TEMPERATURE MONITORING ALERT CONTROL METHOD, SYSTEM AND RELATED DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/119498
Kind Code:
A1
Abstract:
A traction motor bearing temperature monitoring alert control method. Said method not only uses the temperature as the basis for determining a bearing fault of the traction motor, but also takes into account other determination criterions that may generally exist when the bearing of the traction motor fails, effectively determining the actual state of the bearing in a multi-angle and multi-event combination manner, and formulates, according to more comprehensive monitoring parameters, more stringent fault levels and speed limit standards for corresponding levels, guaranteeing the safe and reliable operation of the train. Also disclosed are a traction motor bearing temperature monitoring alert control system, a device, and a computer readable storage medium, which have the beneficial effects above.
