Optical module fault diagnosis and early warning method, device and system

Abstract

The invention discloses an optical module fault diagnosis and early warning method, a device and a system which are used for solving the technical problems that in the prior art, the fault probabilityof an optical module cannot be given, and the adaptability of a model for judging whether the optical module breaks down through a static threshold value method is limited. The method comprises the following steps: acquiring digital diagnosis detection DDM data of a first period of the optical module in real time, processing the DDM data of the first period by adopting an anomaly detection model,and determining a first anomaly vector; according to the first exception vector, calling a sample frequent item set of an exception detection model and a corresponding sample confidence set, and judging whether the first exception vector is matched with an exception vector in the sample frequent item set; if yes, determining that the fault probability of the optical module in the first period isthe sample confidence corresponding to the abnormal vector in the sample frequent item set; and if not, determining that the optical module has no fault in the first period.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a method, device and system for fault diagnosis and early warning of an optical module. Background technique [0002] As an important part of the optical communication network, the optical module is mainly responsible for the conversion of optical signals and electrical signals in the communication process. For a long time, the operation and maintenance of optical modules has been carried out by the operation and maintenance personnel to check the faults of the optical modules and replace or repair them after sensing that the communication services are affected. high. Therefore, it is very necessary to realize the automation and intelligence of optical module operation and maintenance. [0003] At present, the existing optical module fault diagnosis and early warning methods mainly include the following: (1) Based on temperature, usage time and current: estimate t...
