MONITORING AND ALARMING CONTROL METHOD, SYSTEM AND DEVICE FOR TRACTION MOTOR BEARING TEMPERATURE

A monitoring and alarming control method for a traction motor bearing temperature is provided. In the method, whether a bearing of a traction motor is in a failure state is determined based on a temperature of the bearing, and an actual state of the bearing of the traction motor can be effectively determined in conjunction with multiple angles and multiple events, based on other determining basis possibly existing when the bearing of the motor is in the failure state (S101-S104). Strict fault levels and speed limit standards corresponding to the fault levels are defined based on comprehensive monitoring parameters (S105-S107), thereby ensuring a safe and reliable operation of a train. In addition, a monitoring and alarming control system and device for a traction motor bearing temperature and a computer readable storage medium are further provided, which has the above benefits.
