Abstract
Slaves are respectively provided corresponding to electric devices, measure, in real time, power usage states and disposed positions of the electric devices to transmit to a master. The master detects operational states of electric devices on operation based on power usage states received from the slaves, and detects a positional relation between electric devices on operation based on disposed positions of the electric devices. Then, the master estimates the number of residents in the house by determining achievability of operational states of electric devices based on the detected operational states and positional relation of electric devices.
