The invention relates to the technical field of communication
engineering, in particular to a communication optical
cable line intelligent inspection fault point rapid positioning method and device, and the method comprises the steps: obtaining optical
cable line state data, constructing an intelligent fault detection model, recognizing an abnormal
signal through
wavelet transform and a threshold determination method, training an LSTM neural network in combination with historical fault data, and pre-judging a fault type. When a fault is detected, an unmanned aerial
vehicle inspection unit is triggered, an inspection path is planned based on an improved Dijkstra
algorithm according to the fault type and suspected fault area geographic information, an optical
cable line is scanned and detected through a
laser radar, physical fault features are recognized through a YOLOv5
algorithm, and geographic coordinates of a fault point are calibrated in combination with an
inertial navigation system; and fusing sensor data and a detection result, evaluating a fault confidence level by adopting a DS evidence theory, and generating an alarm work order. Therefore, the problems of long positioning time consumption, high omission ratio, difficulty in distinguishing fault types and the like in the prior art are solved.
