Embodiment Construction

[0053] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0054] As a preferred embodiment of the present invention, with reference to the attached Figure 1-2 , this example discloses:

[0055] A method for predicting the remaining life of a contact wire, comprising the following steps:

[0056] S1, obtain the historical data of contact wire wear rate and contact wire wear causative factors, and fit the wear rate-cause factor relationship;

[0057] S2, obtaining the wear amount sequence of a certain position of the contact line at different times under the state where the causative factors are all design values, and fitting the standard state wear-time curve according to the wear amount sequence;

[0058] S3, according to the wear rate-causal factor relationship, calculate the standard state wear rate when the causative factors are all in the design value state, and the actual wear rate ...

Abstract

The invention relates to the technical field of contact network fault prediction and health management, in particular to a contact line residual life prediction method and device, computer equipment and a storage medium. According to the method, a deep residual network is improved, a deep learning technology is adopted to establish a relationship between a contact line abrasion rate and a cause factor thereof, and an actual abrasion curve reflecting an actual state condition is accurately drawn according to a ratio of an actual condition to a standard state abrasion rate in combination with a standard state abrasion curve; therefore, the contact line abrasion is indirectly predicted by detecting related cause factors, and finally the residual life of the contact line is predicted.

Description

technical field [0001] The invention relates to the technical field of catenary fault prediction and health management, in particular to a method, device, computer equipment and storage medium for predicting the remaining life of a catenary. Background technique [0002] The performance optimization of contact wires is closely related to the safe operation of electrified railways. In the working mode of long-term operation without backup, the wear of the contact wire is unavoidable. If the contact wire is replaced before the contact wire wear reaches the extreme value, the failure can be effectively avoided. However, no effective method for predicting the remaining life of the contact wire has been found in the prior art. Contents of the invention [0003] In order to solve the problem that the prior art lacks an effective method for predicting the remaining life of contact wires, the present invention provides the following technical solutions: [0004] A method for pre...
