Optical cable circuit fault positioning and detection method and terminal equipment

Abstract

The invention is applicable to the technical field of optical cable detection, and provides an optical cable circuit fault positioning and detection method and terminal equipment. The method includesthe following steps: establishing an optical cable circuit fault reflected light information sample library according to the reflected light information; establishing an optical cable circuit fault positioning and detection model according to a neural network; determining the theoretical result of the fault position of the optical cable circuit corresponding to the reflected light information in the sample library; judging whether a first difference value of the fault position theoretical result and the optical cable circuit fault position true result corresponding to the reflected light information exceeds a preset first threshold value or not; determining the fault theoretical result if the judgment does not exceed the preset first threshold value; judging whether the second difference value of the fault theoretical result and the fault true result of the optical cable circuit exceeds a preset second threshold value or not; detecting the fault condition of the optical cable circuit to be tested if the judgment does not exceed the preset second threshold value. By adopting the scheme, the accuracy of the fault identification of the optical cable circuit is improved, and the intelligent identification of the fault of the optical cable circuit is realized.

Description

technical field [0001] The invention belongs to the technical field of optical cable detection, and in particular relates to an optical cable line fault location and detection method and terminal equipment. Background technique [0002] With the expansion of the construction scale of my country's communication optical cable lines, and the aging phenomenon of established optical cable lines over time, the possibility of failure of optical cable lines is increasing, and the direct economic losses caused by the interruption of optical cable lines are increasing every year. More and more, the losses caused to the national economy and national defense communications are also staggering. [0003] Then, in the existing optical cable line maintenance method, the judgment of the damage of the optical cable fault is generally judged by the inspection personnel, which is very subjective, and the judgment of the damage standard may be inconsistent, the work efficiency is low, and a large...
