Wire fault identification method and device based on vibration signal, terminal equipment and storage medium

Abstract

The invention discloses a wire fault identification method and device based on a vibration signal, terminal equipment and a storage medium, and the method comprises the steps: firstly decomposing an obtained target vibration signal of a target wire and a plurality of IMF components used for representing different modes of the target vibration signal, and then calculating a correlation coefficient between each IMF component and the target vibration signal; the method comprises the following steps: acquiring a correlation coefficient of a target vibration signal, screening out an IMF component of which the correlation coefficient is higher than a preset threshold value as a target IMF component, calculating target characteristic parameters corresponding to the target IMF component, and inputting the target characteristic parameters into a signal type identification model, so that the signal type identification model determines a target signal type of the target vibration signal after receiving the target characteristic parameters, and finally, determining the fault condition of the target wire according to the determined target signal type. By implementing the invention, the wire fault can be timely and accurately detected and processed, the stability and safety of a power system can be ensured, and the power supply quality is improved.
