Abstract
Example electric appliance identification methods and apparatuses are provided. One example method includes obtaining, by a power line communication (PLC) device, a first noise signal in a circuit. The PLC device can then obtain first data based on the first noise signal, where the first data is used to describe a time-frequency feature of the first noise signal. The PLC device can then obtain, based on an electric appliance identification model and the first data, an electric appliance identification result corresponding to the first noise signal, where the electric appliance identification model is obtained based on a signal including a second noise signal of at least one known electric appliance.
Claims20
An electric appliance identification method, comprising:
- obtaining, by a power line communication (PLC) device, a first noise signal in a circuit;
- obtaining, by the PLC device, first data associated with a time-frequency feature of the first noise signal;
- and
- obtaining, by the PLC device based on an electric appliance identification model and the first data, an electric appliance identification result corresponding to the first noise signal, wherein the electric appliance identification model is obtained based on a signal comprising a second noise signal of at least one known electric appliance.
An electric appliance identification apparatus, comprising:
- at least one processor;
- and
- one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to:
- obtain a first noise signal in a circuit, wherein
- obtain first data associated with a time-frequency feature of the first noise signal;
- and
- obtain, based on an electric appliance identification model and the first data, an electric appliance identification result corresponding to the first noise signal, wherein the electric appliance identification model is obtained based on a second signal comprising a noise signal of at least one known electric appliance.
A computer storage medium, wherein the computer storage medium stores computer-executable instructions, and when being invoked by a computer, the computer-executable instructions cause the computer to perform operations comprising:
- obtaining a first noise signal in a circuit;
- obtaining first data associated with a time-frequency feature of the first noise signal;
- and
- obtaining based on an electric appliance identification model and the first data, an electric appliance identification result corresponding to the first noise signal, wherein the electric appliance identification model is obtained based on a signal comprising a second noise signal of at least one known electric appliance.
