Method and device for locating fault cause and storage medium

Abstract

The embodiment of the invention discloses a method and a device for locating a fault cause and a storage medium. The method comprises the following steps: obtaining parameter values of a plurality ofoperation parameters and a parameter value of a fault parameter within preset duration before a wavelength division single-board device breaks down, wherein the fault parameter is a parameter that anexception occurs when the wavelength division single-board device breaks down; determining the correlation between each operation parameter in the plurality of operation parameters and the fault parameter according to the parameter values of the plurality of operation parameters and the parameter value of the fault parameter, wherein the correlation shows the degree of correlation of the change ofthe parameter values between the operation parameters an the fault parameter; and determining at least one target parameter from the plurality of operation parameters according to the size of the correlations, wherein the correlation between each target parameter of the at least one target parameter and the fault parameter is greater than the correlation between other operation parameters in theplurality of operation parameters except the at least one target parameter and the fault parameter. The embodiment of the invention can improve the accuracy of locating the fault cause.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and storage medium for realizing fault cause location. Background technique [0002] As a transmission technology in optical fiber communication, wavelength division multiplexing (abbreviated as wavelength division) refers to converting the input client signal into a colored light signal that conforms to the Wavelength Division Multiplexing (WDM) standard, so that the same transmission in an optical fiber. WDM veneer, also known as WDM veneer device, is a device that completes wavelength division conversion. Its input end is a variety of signals from customers, and its output end is the converted color light signal that meets the optical transport network standard. WDM boards can be divided into many types according to their functions, corresponding to different optical path combining and splitting functions. Specifically, they can be optical ampl...

Problems solved by technology

[0005] However, there are many components and pins in WDM single-board devices, and the structure is complex, and the influence relationship between the preset parameters of each component is limited by manual experience. Therefore, using this existing technology to locate the cause of the fault is often accurate. lower
