AI Technical Summary
Existing fiber breakage detection technologies have low positioning accuracy, cannot achieve rapid online positioning, cannot automatically identify the cause of fiber breakage, and are not compatible with standard single-mode communication optical fibers, resulting in low efficiency in the allocation of operation and maintenance resources.
Vibration signals from the fiber optic channel are collected using a distributed acoustic sensing system. The signal-to-noise ratio is calculated and the duration is determined. The first-order difference method is used to locate the moment of fiber breakage. Envelope features are extracted and a classifier is used to identify the type of fiber breakage, and a maintenance work order is generated.
It achieves high-precision fiber breakage location and type identification, improves the efficiency of operation and maintenance resource allocation, and generates accurate maintenance guidance.
