Data processing method and device based on unascertained filtering method and storage medium

The invention belongs to the technical field of data monitoring, and particularly relates to a data processing method and device based on an unascertained filtering method and a storage medium. The invention discloses a data processing method based on an unascertained filtering method, and the method comprises the steps: monitoring sequence input, and determining an optimal segmentation value m through a preset particle swarm algorithm; performing segmentation processing on the detection sequence according to the optimal segmentation numerical value m to obtain a plurality of data segments; performing unascertained filtering processing on the plurality of data segments; according to a preset algorithm, performing gross error identification on each data segment and removing gross error data, and outputting a processing result of removing the gross error data; and performing data filling on the processing result through a preset Lagrange interpolation method to obtain accurate monitoring data. And gross error d
