Title:
電力計測システム、電力計測方法および情報処理装置
Document Type and Number:
Japanese Patent JP5644774
Kind Code:
B2
Abstract:
An electric device is provided with an electric power measurement unit that has electric power detection means that measures the amount of consumed electric power and information communication means that transmits a measurement value of the electric power detection means. An electric power meter has information communication means that measures the total amount of electric power consumed indoors and transmits the measurement value. An information processing unit stores the measurement value measured by the electric power detection means and transmitted from the electric power measurement unit and the measurement value of the total amount of consumed electric power transmitted from the electric power meter in every predetermined sampling period. If a difference ± of two measurement values of the electric power detection means is a finite value, the information processing unit calculates and stores both a difference ² of two measurement values of the electric power meter corresponding to the two measurement values and ²/±, and calibrates the amount of electric power that is consumed by the electric device and that is measured by the electric power detection means using a median of a plurality of values of ²/± obtained in a predetermined measurement period or a median of a predetermined number of values of ²/±.
