The invention relates to the technical field of cable asset management and fault prediction, and discloses a cable fault positioning method based on
deep learning clustering analysis test waveform characteristics, and the method comprises the steps: collecting waveform and environment data in a cable operation period, and constructing a historical feature
library comprising waveform, environment and position features; a self-adaptive detection model is adopted, and parameters are dynamically adjusted to adapt to different working conditions; multi-dimensional
feature fusion and matching analysis are combined; a fault point distance is calculated through a
signal propagation model and a
time difference positioning
algorithm, precise positioning is realized by fusing environment compensation and multi-point
cross validation, and a three-dimensional geographic coordinate is generated by combining a laying path; and after multiple verifications, a structured report containing a fault type, a
risk level, a prediction position, confidence and operation and maintenance suggestions is generated. According to the
system, intelligent monitoring, fault risk prediction, asset optimization management and operation and maintenance decision support of a cable operation state are realized, and scientificity and economy of
cable management in a complex environment are improved.
