Electric energy measurement method, device and electric energy meter

Abstract

The invention provides an electric energy metering method, device and electric energy meter, which relate to the technical field of electric energy metering. value; determine whether the power accumulation parameter satisfies the preset power measurement condition; if so, calculate the incremental value of the electric energy corresponding to the power accumulation parameter in the time interval based on the power accumulation parameter and the preset measurement parameter. The electric energy measurement method, device, and electric energy meter provided by the present invention can obtain the accumulated value in time after the value of the pulse register changes, and calculate the incremental value of electric energy, so as to obtain the small increment of electric energy and realize the electric energy meter. The effective display improves the resolution of the energy meter, which can not only avoid the illusion of jumping in the metering display, but also improve the user experience.

Description

technical field [0001] The invention relates to the technical field of electric energy metering, in particular to an electric energy metering method, device and electric energy meter. Background technique [0002] With the rapid development of electronic technology, large-scale integrated circuits have been widely used in electric energy meters. Among them, electronic single-phase AC electric energy meters have good linearity and stability, high measurement accuracy, and strong overload resistance. , low power consumption, strong multi-functionality and other advantages, it has occupied a dominant position in the current electric energy measurement and management. [0003] Usually, according to the current technical specifications in the industry, the electronic single-phase AC energy meter mostly relies on the pulse constant when accumulating electric energy, and the minimum resolution of the electronic single-phase AC energy meter is usually determined by the pulse constan...

[0003] Usually, according to the current technical specifications in the industry, the electronic single-phase AC energy meter mostly relies on the pulse constant when accumulating electric energy, and the minimum resolution of the electronic single-phase AC energy meter is usually determined by the pulse constant , and this kind of resolution can be well displayed when there are fewer digits of decimals for electric energy, but for higher resolution display requirements, it is easy to have the illusion of metering display jumping, which reduces user experience
