Title:
NON-INTRUSIVE LOAD IDENTIFICATION-BASED SUBMETERING SMART ELECTRICITY METER
Document Type and Number:
WIPO Patent Application WO/2019/154050
Kind Code:
A1
Abstract:
A submetering smart electricity meter based on non-intrusive load identification, comprising a non-intrusive load identification module integrated at an inner part of a smart electricity meter, wherein the non-intrusive load identification module may be printed on a circuit main board of the smart electricity meter, or the non-intrusive load identification module is connected to the circuit main board of the smart electricity meter by means of a connector, and the non-intrusive load identification module is installed in a smart electricity meter box or in a module placement bin (1) of the smart electricity meter; and the non-intrusive load identification module is used to identify various types of loads installed indoors, separately calculate a submetering result for each load type, and output corresponding submetering results. Non-intrusive load identification is integrated with existing smart electricity meters, thus improving metering levels of the existing smart electricity meters, and providing more abundant power consumption information to a user. The present invention has good application prospects.
