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 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. This method improves the deep residual network, uses deep learning technology to establish the relationship between the wear rate of the contact line and its causative factors, and accurately draws the actual state according to the ratio of the wear rate between the actual situation and the standard state combined with the standard state wear curve. The actual wear curve below, and then indirectly predict the wear of the contact wire by detecting the relevant causative factors, and finally realize the prediction of the remaining life of the contact wire.

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...
