Example Embodiment

[0056] Example 1

[0057] In this embodiment, a method for predicting turnout failure is provided, figure 1 Is a flowchart of a fault prediction method according to an embodiment of the present invention, such as figure 1 As shown, the flowchart includes the following steps:

[0058] Step S11, collecting N consecutive normal action curves of the same turnout;

[0059] Step S12, extract representative features for each action curve;

[0060] Step S13: Establish prediction models for the similar characteristics of the N curves;

[0061] Step S14: Calculate the Y-th turnout based on the prediction model (Y> N) The value of each type of feature during the action;

[0062] Step S15: Obtain the predicted curve of the Y-th turnout movement based on the characteristic value obtained by the prediction model;

[0063] Step S16: Perform fault diagnosis on the Y-th action prediction curve of the turnout to determine whether it is faulty.

[0064] Through the above steps, scientific methods are used ...

Abstract

The invention provides a turnout failure prediction method. The turnout failure prediction method comprises the steps that continuous N normal action curves of the same turnout are acquired; representative characteristics of the normal action curves are extracted; prediction models are established respectively for like categories of characteristics of the N normal action curves; based on the prediction models, values of each category of characteristics during Y action (Y > N) of the turnout are respectively calculated; failure diagnosis is conducted on a Y action prediction curve of the turnout, and whether failure is produced or not is judged. By adopting the method, the working state and the residual service life of the turnout at a next stage can be predicted, a reference is provided for maintenance decision making optimization, early turnout failure prevention is achieved, the turnout accident rate is reduced, the system reliability is improved, and traffic safety is ensured.

Description

technical field [0001] The invention relates to the field of rail transit, in particular to a method for predicting a turnout failure. Background technique [0002] Turnout is an essential line equipment when a train transfers from one track to or crosses another track. It is an important part of the railway track and is also the equipment with the highest failure rate. Once the turnout breaks down and cannot complete the prescribed action, the time delay will be caused by temporary parking, or the derailment of the carriage will cause casualties. [0003] my country's frequent railway transportation operations and changing operating environments can easily lead to turnout failures, but the existing monitoring conditions and maintenance methods for turnouts are backward, which can easily cause traffic accidents or affect traffic efficiency. At present, in order to prevent accidents, the railway department arranges professionals to regularly check and repair the turnouts, wh...
