Abstract

The invention provides a method for evaluation and early warning for train axle properties based on mathematical models and belongs to the field of methods for evaluation and early warning of high speed train axle properties. The method comprises the steps of establishing an axle temperature variation mathematical model for axle operation in each of the latest 30 days, and obtaining a group of parameters for evaluating the axle properties with respect to each model; performing smoothing processing on each group of parameters, and performing abrupt change detection and trend detection for the axle properties based on the smoothed property parameters. The qualitative method can assist train maintainers in accurately and reliably judging whether axle temperature alarm signals belong to short-period false alarms capable of self-recovery, and further provide important reference bases for maintenance decisions thereof.

Description

technical field

[0001] The invention belongs to the field of evaluation and early warning methods for the axle performance of high-speed train sets, and in particular relates to a method for evaluating and early warning the performance of train axles based on a mathematical model. Background technique

[0002] The TCMS (Train Control and Management System) train control and management system of high-speed EMUs has functions such as intelligent distributed information collection, storage, logic judgment, alarm indication and human-computer interaction. In addition to the axle temperature sensor data, other sensors are also used to collect and store the train running speed data and the vehicle external environment temperature data respectively. The axle temperature characteristics of the axle can reflect the performance of the axle to a certain extent, which is very important for judging the nature of the axle fault, but the existing TCMS system does not have the intelligent a...
