Abstract
(DE)
Es wird ein Verfahren zum Bereitstellen von Messwerten einer technischen Anlage (2) vorgeschlagen, bei dem Messwerte (7) mindestens einer Messreihe erfasst werden, wobei ein jeweiliger Messwert von einem Messsensor (MS1-MSm) für eine jeweilige physikalische Messgröße in der technischen Anlage (2) für einen jeweiligen Messzeitpunkt bereitgestellt ist, und die Messwerte mit Hilfe eines Schwellwertvergleichs und mindestens einer weiteren Verfahrensstufe als normale Messwerte (10) oder anomale Messwerte (11) kategorisiert werden, wobei die weitere Verfahrensstufe ein Berechnen eines oder mehrerer statistischer Lageparameter für ausgewählte Messwerte aus einer selben und/oder unterschiedlichen Messreihen umfasst. Durch das Verfahren kann die Zuverlässigkeit der bereitgestellten Messwerte gesteigert werden. Außerdem werden ein technisches System (1) mit der technischen Anlage (2), mindestens einem Messsensor (MS1-MSm) und einer programmgesteuerten Einrichtung (4) sowie ein Verfahren zum Betreiben des technischen Systems (1) vorgeschlagen.
(EN)
A method for providing measured values for a technical installation (2) is proposed in which measured values (7) of at least one measurement series are captured, wherein a respective measured value is provided by a measurement sensor (MS1-MSm) for a respective physical measured variable in the technical installation (2) for a respective measurement time, and the measured values are categorised as normal measured values (10) or anomalous measured values (11) by means of a threshold value comparison and at least one further method step, the further method step comprising computation of one or more statistical position parameters for selected measured values from one and the same and/or different measurement series. The method can increase the reliability of the measured values provided. Moreover, a technical system (1) having the technical installation (2), having at least one measurement sensor (MS1-MSm) and having a program-controlled device (4) and a method for operating the technical system (1) are proposed.
(FR)
L’invention concerne un procédé pour fournir des valeurs de mesure d’une installation technique (2), consistant à acquérir des valeurs de mesure (7) d’au moins une série de mesures, une valeur de mesure respective étant fournie par un capteur de mesure (MS1-MSm) pour une grandeur de mesure physique respective dans l’installation technique (2) à un moment de mesure respectif, et à catégoriser les valeurs de mesure comme valeurs de mesure normales (10) ou valeurs de mesure anormales (11), au moyen d’une comparaison de valeurs seuil et d’au moins une étape de procédé supplémentaire, cette étape de procédé supplémentaire comprenant un calcul d’un ou plusieurs paramètres de position statistique pour des valeurs de mesure sélectionnées d’une série de mesure identique et/ou différente. Le procédé selon l’invention permet d’accroître la fiabilité des valeurs de mesure fournies. Cette invention concerne en outre un système technique (1) comprenant une installation technique (2), au moins un capteur de mesure (MS1-MSm) et un dispositif commandé par programme (4), ainsi qu’un procédé pour faire fonctionner ledit système technique (1).
