Traction motor bearing temperature monitoring alarm control method and system and related device

Abstract

The invention discloses a traction motor bearing temperature monitoring alarm control method. The traction motor bearing temperature monitoring alarm control method not only utilizes the temperature as a criterion for a traction motor bearing failure, but also combines other criterions which normally and probably exist when a traction motor bearing fails. An actual state of the bearing is effectively judged by a method of multiple-perspective and multi-event combination, and more rigorous failure levels and speed limit standards under the corresponding levels are established based on more comprehensive monitoring parameters to ensure the safe and reliable operation of a train. The invention further discloses a traction motor bearing temperature monitoring alarm control system and device and a computer readable storage medium. The traction motor bearing temperature monitoring alarm control system and device and the computer readable storage medium have the above beneficial effects.

Description

technical field [0001] The present application relates to the technical field of traction motor fault monitoring, in particular to a traction motor shaft temperature monitoring and alarm control method, system, device and computer-readable storage medium. Background technique [0002] As the speed of EMU trains increases, the impact, dynamic effect and vibration of the train on the rails increase, and the safety requirements for the rotating parts of the train are higher. The traction motor is the key rotating part of the EMU. It is generally installed on the train bogie and is crucial to the safety of the train at high speed. When the bearings are worn or defective, it will affect the safety of the train. [0003] The traditional traction motor bearing monitoring system only monitors the bearing temperature, and monitors and alarms the EMU according to the bearing temperature limit, which is divided into two levels of alarms. Level one alarm: bearing temperature T>120°C...

AI Technical Summary

Problems solved by technology

The monitoring and alarm method is relatively simple, which cannot effectively ensure the safe operation of the EMU. It is not accurate enough to judge the bearing damage state simply by temperature. In the case of a high degree of bearing damage, the maximum speed limit level is 140km / h, which still poses a safety hazard to the train operation. , if necessary, further increase the alarm level and further reduce the speed
