Title:
METHOD AND DEVICE FOR IDENTIFYING ELECTRICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/248946
Kind Code:
A1
Abstract:
A method and device for identifying an electrical device. The method comprises: a PLC apparatus acquiring a noise signal in a circuit; the PLC apparatus acquiring first data on the basis of the noise signal, the first data describing a time-frequency feature of the noise signal; and the PLC apparatus acquiring, on the basis of an electrical device identification model and the first data, an electrical device identification result corresponding to the noise signal, wherein the electrical device identification model is obtained on the basis of signals including a noise signal of at least one known electrical device, The invention directly employs a PLC apparatus to collect a noise signal and to extract a time-frequency feature therefrom as first data without relying on an additional apparatus, such as a smart electricity meter, and identifies an electrical device severely interfering with lines on the basis of an electrical device identification model.
