A power digital inspection monitoring method and system based on remote diagnosis

Abstract

The application discloses a power digital inspection monitoring method and system based on remote diagnosis, relates to the technical field of power inspection monitoring, and comprises the following steps: acquiring a discrete sampling sequence output by a front-end collection channel; determining a full-scale flat-top section and a non-saturation transition section in the discrete sampling sequence; performing morphology reconstruction on the full-scale flat-top section according to the non-saturation transition section to obtain a reconstructed sampling sequence; performing difference comparison on the reconstructed sampling sequence and the discrete sampling sequence to determine a transient interference saturation determination result; and replacing the full-scale flat-top section in the discrete sampling sequence with the reconstructed sampling sequence based on the transient interference saturation determination result to obtain a real physical quantity diagnosis sequence. The application eliminates false square wave data caused by saturation truncation, restores a real physical quantity attenuation process, and avoids false fault diagnosis.
