Title: INDICATOR DETECTION SYSTEM AND INDICATOR DETECTION METHOD
Abstract:
An indicator detection system equipped with: a data acquisition unit for acquiring operation data for a machine and operation history data indicating the operation history of the machine; an estimation unit for calculating an estimated value for a parameter of the machine that is being monitored, on the basis of the operation data, the operation history data, and an estimation model for estimating the value of the parameter at a point in time corresponding to the operation history data; and a state evaluation unit for evaluating the state of the machine on the basis of the deviation between the estimated value of the parameter from the estimation unit and a measured value or an estimated value for the parameter included in the operation data acquired by the data acquisition unit.
