Document Type and Number:
WIPO Patent Application WO/2022/137916
Kind Code:
A1
Abstract:
A threshold value calculation device according to the present invention calculates a threshold value used in an abnormality detection device for detecting abnormal communication in a first device in a facility in which a home network (11) is installed. A second device different from the first device is provided in the facility. The threshold value calculation device is provided with: a device state acquisition unit (110) for acquiring a device state of the first device in a first time period; a room occupancy situation determination unit (120) for determining a room occupancy situation of a person who is present in the facility in the first time period on the basis of information acquired from the second device; a communication log collection unit (130) for collecting a communication log generated by communication transmitted and received by the first device in the first time period; and a learning unit (140) for calculating a threshold value for communication in the first device in a second time period subsequent to the first time period on the basis of the device state, the room occupancy situation, and the communication log. The device state includes at least one state of the first device, the room occupancy situation includes at least one situation of the person, and the learning unit (140) calculates a threshold value for each combination of the at least one state and the at least one situation.
