PROBLEM TO BE SOLVED: To provide an abnormality detection system and program capable of easily detecting an abnormality of equipment using measured values which are collected during ordinary operation of the equipment.SOLUTION: The abnormality detection system includes: a related measured value selection section 12 that calculates a correlation coefficient between a determination object measured value (power consumption) measured on an air conditioner 4a as an abnormality determination object and respective measured values (comparison measured value) measured by various measurement equipment 5 to select a comparison measured value which reaches a predetermined value or more exceeding an average value of correlation coefficients from within comparison measured values, as a related measured value; and an abnormality detection section 13 that divides an abnormality detection object period into plural pieces, calculates a correlation coefficient between the determination object measured value and the related measured value for respective divided periods, and when the calculated correlation coefficient is smaller than a threshold value, determines that an abnormality has occurred on the air conditioner 4a in the period. |
