Title:
SINGLE-PHASE ELECTRIC ENERGY METERING CHIP AND INTELLIGENT INTERNET-OF-THINGS METER BASED ON IR46 STANDARD
Document Type and Number:
WIPO Patent Application WO/2023/124206
Kind Code:
A1
Abstract:
A single-phase electric energy metering chip and intelligent Internet-of-Things meter based on an IR46 standard. The single-phase electric energy metering chip comprises a current/voltage signal collection and correction unit, a full-wave measurement and metering unit, a harmonic measurement and metering unit, an original waveform data processing unit, a terminal temperature measurement unit, a communication interface, an energy output interface and an original waveform data output port, wherein the current/voltage signal collection and correction unit is used for performing analog-to-digital conversion on a voltage/current signal and performing phase and gain correction; the full-wave measurement and metering unit is used for obtaining full-wave data; the harmonic measurement and metering unit is used for obtaining harmonic data; the original waveform data processing unit is used for obtaining original waveform data; and the terminal temperature measurement unit is used for obtaining terminal temperature measurement data. The single-phase electric energy metering chip solves the problem of electrical isolation and the problem of a reliable connection between modules, thereby reducing the development and production costs of a next-generation intelligent Internet-of-Things meter.
