Device state detection device, device state detection method, device state detection server and device state detection system, and consumer abnormality detection device, consumer abnormality detection system and consumer abnormality detection method, and device state database maintenance server
A device state detection device or the like is obtained that has less time and effort to learn a combination of operating states of all devices existing in the home, and has few estimation errors even when an unknown device operates. A measuring unit 110 that measures a physical quantity of an environment in which the device is installed; a feature amount calculating unit 120 that calculates a feature amount of a measurement value measured by the measuring unit 110; A storage unit 140 that stores a corresponding device state as a reference device entry dictionary 200, and a feature amount stored in the reference device entry dictionary 200 using the feature amount calculated by the feature amount calculation unit 120 as a search key; And a device state detecting unit for detecting a device state based on the device state corresponding to the searched feature amount.
