OTDR-based optical cable fault positioning and pushing method for big data analysis

Abstract

The invention discloses an OTDR-based optical cable fault positioning and pushing method for big data analysis, and relates to the technical field of optical cable fault detection. Aiming at the defect that the fault position is difficult to accurately analyze by manually detecting OTDR data, the invention employs the scheme that the method comprises the following steps: acquiring alarm information of a plurality of telecommunication network units in real time through an EMS system; processing the alarm information acquired by the EMS system by using the big data cluster real-time stream, andgenerating an optical fiber fault event; enabling the big data cluster to actively initiate OTDR detection to a telecommunication network unit corresponding to the EMS system through an OTDR detectionmodule, determining a fault point according to a detection result and GIS basic resources, and then adding determined fault point position information into an optical fiber fault event to form a fiber breaking event; enabling the front-end application to extract a fiber breaking fault event and pushing the event to an AI monitoring management module, and enabling the AI monitoring management module to generate fault alarm information and intelligently send the fault alarm information to operation and maintenance personnel for processing. According to the invention, accurate positioning and efficient and timely operation and maintenance management of optical cable faults are realized.

Description

technical field [0001] The invention relates to an optical fiber communication fault detection technology, in particular to an optical cable fault location and push method based on OTDR for big data analysis. Background technique [0002] With the wide application of optical fibers in the field of communication, optical fiber fault detection devices are essential in the construction and detection of optical fibers. [0003] In the prior art, a red light fault detection technology or an Optical Time Domain Reflectometer (OTDR, Optical Time Domain Reflectometer) is generally used. Among them, the red light fault detection technology utilizes the visibility of red light to realize the precise location of the fault point through the transmission of red light through the fault of the optical fiber. Probing requires enormous manpower. OTDR is an instrument that understands the uniformity, defects, fractures, and connector coupling of optical fibers through the analysis of measur...

AI Technical Summary

Problems solved by technology

Most telecom operation and maintenance personnel need to manually detect the broken fiber with OTDR instrument equipment after receiving the fault work order for the fault of the optical cable, and locate the fault point by manual analysis. Because the optical fiber has a length of disk at the joint point, it is difficult to accurately locate the fault The location, the fault problem is not real-time accurate enough
