摘要

PROBLEM TO BE SOLVED: To provide an electric energy measuring system which copes with various needs.;SOLUTION: This system is provided with: an electric power computing circuit 30 for generating a measuring pulses corresponding to the number of calculated electric power based on an input current and voltage; a full-day electric energy memory 81 for integrating the minimum measuring unit value in every time when the number of the measuring pulses received from the electric power computing circuit 30 exceeds a value corresponding to the minimum unit; a plurality of time zone memories 85₁-85₆ for storing the electric energy classified by time zones; a demand supply calendar 83 for storing a measuring pattern; a clocking mechanism 82 for clocking a time; and a classifying part 84 for selecting anyone of the plurality of time zone memories 85₁-85₆ to integrate the measuring unit values, every time when a content of the full-day electric energy memory 81 reaches a prescribed measuring unit value by the integration of the minimum measuring unit values, based on the measuring pattern stored in the demand supply calendar 83 and a time clocked by the clocking mechanism 82.;COPYRIGHT: (C)2005,JPO&NCIPI
