Demand target display device

摘要

The conventional demand target display device based on time information differing from the information used by electric power companies and electric power consumers causes a divergence regarding their demand values. Therefore, a demand target display device with a dual-purpose scale, which acquires AC signals based on the AC waveform of AC power from a power supply line, generates time information based on the acquired AC signals, transmits the generated time information via radio waves within a housing, receives the transmitted time information via radio waves within the housing, indicates the time on the dual-purpose scale based on the received information, acquires electrical energy consumption within a segment for a given target demand value including the current time, and indicates the relationship between the acquired electrical energy consumption within a segment recorded and a target demand value set for such segment, is proposed.

主权项

1. A demand target display device; comprising:
a dual-purpose scale for indicating time and electrical energy consumption; a time indication unit for indicating time via the dual-purpose scale; an electrical energy consumption acquisition unit for acquiring electrical energy consumed up to the current time within a given segment for a given target demand value including the current time; a goal achievement indication unit for indicating the relationship between electrical energy consumption within a given segment recorded via the electrical energy consumption acquisition unit and a target demand value set for such segment; an AC signal acquisition unit for acquiring AC signals based on the AC waveform of AC power from a power supply line; a time information generation unit for generating time information based on the acquired AC signals; a transmission unit for transmitting the generated time information via radio waves within a housing; a reception unit for receiving the transmitted time information via radio waves within the housing; and a time indication unit control unit for controlling the time indication unit via the received time information.
