PROBLEM TO BE SOLVED: To enable a user to simply estimate power consumption without mounting a power consumption measuring device to individual equipment while the user lives.SOLUTION: An electric equipment monitoring device includes a power consumption calculator, a feature amount calculator, a detector, and an individual equipment power consumption calculator. The feature amount calculator calculates a feature amount based on at least one of a current signal and a voltage signal of a power supply unit for supplying power to plural equipment. The power consumption calculator calculates power consumption of the plural equipment. The detector detects the time of operation of the equipment. The individual device power consumption calculator acquires a power consumption difference as the difference between the power consumption calculated by the power consumption calculator and the power consumption at the time of the operation during a first period from the time of the operation, acquires a feature amount difference as the difference between the feature amount calculated by the feature amount calculator and the feature amount at the time of the operation, and calculates the power consumption of the equipment from the feature amount difference, the power consumption difference and the feature amount calculated by the feature amount calculator.SELECTED DRAWING: Figure 1 |
