ELECTRICAL APPARATUS ESTIMATION DEVICE, METHOD OF THE SAME, AND PROGRAM

Title:

ELECTRICAL APPARATUS ESTIMATION DEVICE, METHOD OF THE SAME, AND PROGRAM

Document Type and Number:

Japanese Patent JP2013218715

Kind Code:

A

Abstract:

To establish a method for easily calculating and adjusting parameters without requiring a database in advance, when estimating an electrical apparatus from current information to be acquired.

A sensor part 21 acquires time series data on total value of current consumption composed of combination of usage states of a plurality of electrical apparatuses installed in each space in a house. A parameter estimation part 22 calculates a model parameter when operation states of the plurality of electrical apparatuses are modeled by using a probability model on the basis of the acquired time series data. This invention is applicable, for example, for an electrical apparatus estimation device for estimating the electrical apparatus connected to a distribution board, on the basis of information on current measured at the distribution board.
