Title:
ANOMALY SERIOUSNESS COMPUTATION SYSTEM, ANOMALY SERIOUSNESS COMPUTATION DEVICE, AND ANOMALY SERIOUSNESS COMPUTATION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2018/216197
Kind Code:
A1
Abstract:
On the basis of a plurality of detection value information acquired by a sensor group (12) when each device in a building (18) operates normally, a forecasted value computation unit (40) computes a forecasted detection value forecast to be detected by each of the sensors if the devices are operating normally. On the basis of the difference between the forecasted detection value for each of the sensors and the actual detection value for each of the sensors, a degree-of-anomaly computation unit (42) computes a degree of anomaly of each of the sensors. On the basis of the degree of anomaly for not only a given sensor at anomaly detection time when an anomalous value is detected by said sensor, but also the degrees of anomaly for other sensors which are sensors other than the sensor of interest at anomaly detection time, an anomaly seriousness computation unit (46) computes an anomaly seriousness for the sensor of interest.
