METHOD FOR THE AUTOMATED IN-LINE DETECTION OF DEVIATIONS OF AN ACTUAL STATE OF A FLUID FROM A REFERENCE STATE OF THE FLUID ON THE BASIS OF STATISTICAL METHODS, IN PARTICULAR FOR MONITORING A DRINKING WATER SUPPLY
METHOD FOR THE AUTOMATED IN-LINE DETECTION OF DEVIATIONS OF AN ACTUAL STATE OF A FLUID FROM A REFERENCE STATE OF THE FLUID ON THE BASIS OF STATISTICAL METHODS, IN PARTICULAR FOR MONITORING A DRINKING WATER SUPPLY
A method for automated in-line detection of deviations of an actual state of a fluid from a reference state is disclosed wherein measured values captured at the same time are evaluated in a combined manner with respect to at least three measurement variables that are different measurement quantities of the fluid and/or a measurement quantity of the fluid measured at different measuring points. The method includes creating a reference data set, wherein reference measured values are mapped to a reference vector of a vector space using a neural network; in-line measurement, wherein measured values at all times are mapped to a measurement vector using the neural network; comparing the measurement vector with the reference vectors using a kernel density estimator of a predefinable window width; and creating an assessment with respect to a deviation of the actual state from the reference state on the basis of the kernel density estimator.
