STATE DETECTION DEVICE, STATE DETECTION METHOD AND COMPUTER PROGRAM

To provide a state detection device that is able to accurately detect a state by accurately specifying an estimated value for determining a state such as anomaly.SOLUTION: A state detection device 100 according to one embodiment includes: a numerical value acquiring unit 101 that acquires an actual opening degree and a target opening degree of a flow rate adjustment valve 16 as specific numerical values that are continuously detected and/or specified; an estimated value specifying unit 102 that, based on the plurality of specific numerical values (the actual opening degree and the target opening degree) acquired by the numerical value acquiring unit 101, specifies an estimated value of an actual opening degree that is a specific numerical value following the plurality of specific numerical values. When a difference between the estimated value corresponding to the actual opening degree and the actual opening degree corresponding to the estimated value is equal to or greater than a predetermined value, the estimated value specifying unit 102 replaces the estimated value with the actual opening degree corresponding to the estimated value and specifies a following estimated value and an estimated value after that.SELECTED DRAWING: Figure 2 【課題】異常などの状態を判定するための予測値を的確に特定することで、状態を的確に検知できる状態検知装置の提供。【解決手段】一実施の形態に係る状態検知装置１００は、連続的に検出される及び／又は特定される具体的数値としての流量調節弁１６の実際の開度及び目標の開度を取得する数値取得部１０１と、数値取得部１０１で取得される複数の具体的数値（実際の開度及び目標の開度）に基づき、複数の具体的数値の次の具体的数値である実際の開度の予測値を特定する予測値特定部１０２と、を備える。そして、予測値特定部１０２は、実際の開度に対応する予測値と当該予測値に対応する実際の開度との差分が所定値以上である場合に、当該予測値を、これに対応する実際の開度と置き換えて、次の予測値及びその後の予測値の特定を行う。【選択図】図２
