Periodic monitoring method and device for submarine cable disturbance sensing data

The invention relates to a periodic monitoring method and device for submarine cable disturbance sensing data. Target data are obtained by acquiring disturbance sensing data, collected by a plurality of sensors, of a submarine cable and performing data preprocessing. Judging the target data by using N algorithms in a preset algorithm pool to obtain a periodic data set with the length of N; m periodic data subsets are selected from a periodic data set with the length being N, the M periodic data subsets correspond to M base classifiers respectively, and a target classifier is obtained according to the base classifiers with the results meeting a preset threshold value and the weights of the base classifiers with the results meeting the preset threshold value, and determining a periodic result of the submarine cable disturbance sensing data according to an output result of the target classifier. The state of the submarine equipment and periodic monitoring of the submarine cable disturbance sensing data can be au
