MANHOLE PUMP DIAGNOSING METHOD AND MANHOLE PUMP DIAGNOSING DEVICE
To provide a manhole pump diagnosing method that can perform, even with a small physical quantity, an accurate diagnosis of an abnormality due to various causes.SOLUTION: A manhole pump diagnosing method includes: a sampling step of calculating, on the basis of an operating time per actuation of each manhole pump within a predetermined diagnosis time period, average operating times as a pair of characteristic values; a normalizing step of normalizing the pair of calculated characteristic values; a diagnosing step of plotting the pair of normalized characteristic values on a two-dimensional coordinate system, and performing a primary diagnosis on the normality or abnormality of each manhole pump on the basis of which side the plotted characteristic value point is present across a preset boundary threshold; and a diagnosis map which has the external side of the boundary threshold that is set in the two-dimensional coordinate system divided into a plurality of regions, and has each region associated with any one of the abnormality causes. The diagnosing step is for diagnosing the abnormality cause on the basis of the region where each characteristic value point is plotted on the diagnosis map.SELECTED DRAWING: Figure 3
【課題】少ない物理量であっても様々な原因による異常診断が的確に行なえるマンホールポンプの診断方法を提供する。【解決手段】所定の診断対象期間内の各マンホールポンプの１起動当りの運転時間に基づき、各均運転時間を一対の特性値として算出するサンプリングステップと、算出された一対の特性値を正規化する正規化ステップと、正規化された一対の特性値を２次元座標系にプロットし、プロットした特性値点が予め設定された境界閾値の何れの側に存在するかに基づいて各マンホールポンプの正常または異常を一次診断する診断ステップと、２次元座標系に設定された境界閾値の外側が複数の領域に区分され、各区分が異常原因の何れかと関連付けられた診断マップを備え、診断ステップは、各特性値点が前記診断マップにプロットされた領域に基づいて異常原因を診断するマンホールポンプの診断方法。【選択図】図３
