Abnormality importance calculation system, abnormality importance calculation device, and abnormality importance calculation program

摘要

If the predicted value calculation unit (40) operates normally based on a plurality of pieces of detection value information acquired by the sensor group (12) when each device in the building (18) is operating normally. For example, a detection prediction value predicted to be detected by each sensor is calculated. The abnormality degree calculation unit (42) calculates the abnormality degree of each sensor based on the difference between the predicted detection value of each sensor and the actual detection value of each sensor. The abnormality importance degree calculation unit (46) determines not only the abnormality level of the sensor when an abnormality is detected by a certain sensor but also the abnormality level of another sensor which is a sensor other than the sensor of interest at the time of abnormality detection. Is also used to calculate the degree of abnormality importance of the sensor of interest.
