Title:
ポンプシステムの現在の動作状態を１つ以上の故障シナリオと関連付けるポンプ監視システム及び方法
Document Type and Number:
Japanese Patent JP7453484
Kind Code:
B2
Abstract:
A pump monitoring system for associating a current operating state of a pump system (1) comprising n ≥ 1 pumps (3) with one or more of k ≥ 1 fault scenarios, wherein the pump monitoring system comprises- an interface module for receiving at least one set of m ≥ 2 operational values from the pump system, wherein the m operational values define a current operational point in an m-dimensional operating space, and- a processing module (11) for processing the operational values received by the interface module,wherein the processing module (11) is configured to consult given or determined model parameters describing a non-faulty model pump characteristic in the m-dimensional operating space, wherein the processing module (11) is further configured to determine a k-dimensional decision vector with k decision vector components being indicative of a deviation between- an actual differential volume in the m-dimensional operating space based on distances between the m operational values and the non-faulty model pump characteristic, and- a modelled differential volume in the m-dimensional operating space for the respective fault scenario.
