Optical cable fault rapid positioning method based on thermal infrared detection technology

Abstract

The invention provides an optical cable fault rapid positioning method based on a thermal infrared detection technology, which is used to rapidly search the position of a breakpoint of an optical fiber core of a faulty optical cable. The positioning method comprises the following steps of: S1, judging a faulty fiber core with a breakpoint in a faulty optical cable, and preliminarily judging an area where the breakpoint of the fiber core is located so as to carry out troubleshooting; S2, inputting high-power laser into the faulty fiber core at the optical signal access point closest to the breakpoint of the faulty fiber core, so as to increase the temperature of the breakpoint of the faulty fiber core in the optical cable fault area; and S3, searching a high-temperature point in the fault area by adopting a thermal infrared detector so as to accurately position the breakpoint of the faulty fiber core; According to the invention, the efficiency of optical fiber breakpoint troubleshooting can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of optical cable maintenance, in particular to a method for quickly locating optical cable faults based on thermal infrared detection technology. Background technique [0002] The most common faults of the optical cable are the interruption of the optical cable caused by construction breakage, disaster weather, small animal bites, etc. At present, the fault finding of the optical cable is only done by testing the optical cable through OTDR and other instruments to obtain the distance of the fault point, and then relying on manual Large-scale search on the spot with the naked eye. [0003] From the analysis of the existing emergency repair of optical cable faults, the average time for troubleshooting and locating fault points in the traditional manual naked eye search mode accounts for half or more of the entire fault repair time, especially at night, in bad weather and other special moments, or when the opti...

[0003] From the analysis of the existing emergency repair of optical cable faults, the average time for troubleshooting and locating fault points in the traditional manual naked eye search mode accounts for half or more of the entire fault repair time, especially at night, in bad weather and other special moments, or when the optical cable line is detoured on the mountain. When the traffic is inconvenient and the environment is more complicated, such as walking between trees, etc., the time will be longer, resulting in long time-consuming, low efficiency and high labor costs for the entire emergency repair process.
