Abstract
Official abstract text for this publication.
A monitoring device (10) includes a feature amount storage unit (11) that stores a device feature amount which is a feature amount of each of a plurality of electrical devices installed in a predetermined unit in operation; a measured data acquisition unit (12) that acquires measured data of the predetermined unit which is at least one of a total current consumption, a total power consumption, and a voltage measured in the predetermined unit; a feature amount extraction unit (13) that acquires a measurement feature amount which is the feature amount included in the measured data of the predetermined unit; a correction unit (15) that corrects a first feature amount which is the device feature amount or the measurement feature amount based on unit feature information indicating a feature of the predetermined unit; and a presumption unit (16) that presumes the electrical device being in operation using the corrected first feature amount, and a second feature amount which is the device feature amount or the measurement feature amount, and a different feature amount from the first feature amount.
First claim
Opening claim text (preview).
The invention claimed is: 1. A correction information generation device comprising: a measured data acquisition unit that acquires measured data of a predetermined unit which is at least one of a total current consumption, a total power consumption, and a voltage of an electrical device measured in a first environment; a reference data storage unit that acquires reference data which is at least one of a total current consumption, a total power consumption, and a voltage of the electrical device measured in a second environment different from the first environment; and a correction unit that generates correction information for cancelling a difference between the measured data of the predetermined unit and the reference data based on the measured data of the predetermined unit and the reference data. 2. A correction information generation device comprising: a measured data acquisition unit that acquires measured data of a predetermined unit which is at least one of a total current consumption, a total power consumption, and a voltage of an electrical device measured in a first environment; a measurement feature amount extraction unit that acquires a measurement feature amount which is a feature amount included in the measured data of the predetermined unit; a reference data storage unit that acquires reference data which is at least one of a total current consumption, a total power consumption, and a voltage of the electrical device measured in a second environment different from the first environment; a device feature amount extraction unit that acquires a device feature amount which is a feature amount included in the reference data; and a correction unit that generates correction information for cancelling a difference between the device feature amount and the measurement feature amount based on the device feature amount and the measurement feature amount. 3. A non-transitory storage medium storing a program causing a computer to function as: a measured data acquisition unit that acquires measured data of a predetermined unit which is at least one of a total current consumption, a total power consumption, and a voltage of an electrical device measured in a first environment; a reference data storage unit that acquires reference data which is at least one of a total current consumption, a total power consumption, and a voltage of the electrical device measured in a second environment different from the first environment; and a correction unit that generates correction information for cancelling a difference between the measured data of the predetermined unit and the reference data based on the measured data of the predetermined unit and the reference data. 4. A non-transitory storage medium storing a program causing a computer to function as: a measured data acquisition unit that acquires measured data of a predetermined unit which is at least one of a total current consumption, a total power consumption, and a voltage of an electrical device measured in a first environment; a measurement feature amount extraction unit that acquires a measurement feature amount which is a feature amount included in the measured data of the predetermined unit; a reference data storage unit that acquires reference data which is at least one of a total current consumption, a total power consumption, and a voltage of the electrical device measured in a second environment different from the first environment; a device feature amount extraction unit that acquires a device feature amount which is a feature amount included in the reference data; and a correction unit that generates correction information for cancelling a difference between the device feature amount and the measurement feature amount based on the device feature amount and the measurement feature amount. 5. A correction information generation method performed by a computer, the method comprising the steps of: acquiring measured data of a predetermined unit which is at least one of a total current consumption, a total power consumption, and a voltage of an electrical device measured in a first environment; acquiring reference data which is at least one of a total current consumption, a total power consumption, and a voltage of the electrical device measured in a second environment different from the first environment; and generating correction information for cancelling a difference between the measured data of the predetermined unit and the reference data based on the measured data of the predetermined unit and the reference data. 6. A correction information generation method performed by a computer, the method comprising the steps of: acquiring measured data of a predetermined unit which is at least one of a total current consumption, a total power consumption, and a voltage of an electrical device measured in a first environment; acquiring a measurement feature amount which is a feature amount included in the measured data of the predetermined unit; acquiring reference data which is at least one of a total current consumption, a total power consumption, and a voltage of the electrical device measured in a second environment different from the first environment; acquiring a device feature amount which is a feature amount included in the reference data; and generating correction information for cancelling a difference between the device feature amount and the measurement feature amount based on the device feature amount and the measurement feature amount.
