摘要

A user situation confirmation system for confirming the situation of a user using an electric apparatus, the user situation confirmation system being provided with a detection device for detecting the amount of electric power consumed by the electric apparatus and an electric power information collection device capable of communicating with the detection device. The electric power information collection device is configured so that the electric power information collection device calculates a moving average value, in a period longer than a fixed period, of the amounts of electric power consumed by the electric apparatus per fixed period that are collected by the electric power information collection device, and, when, with regard to the amounts of electric power consumed by the electric apparatus in the fixed period that are collected by the electric power information collection device, there is no change in the consumed amount of electric power in the latest fixed period from the consumed amount of electric power in the fixed period immediately preceding the latest fixed period exceeding or falling below the moving average value consecutively for a specific period, the electric power information collection device executes a notification operation.
