Abstract
(DE)
Verfahren zur Ermittlung des Auftretens einer Störstelle (11) einer Leitung (10) mittels Schätzung, wobei zumindest ein erster Indikator (40) durch ein, an einem ersten Erfassungsort (30) zugeordnetes erstes Erfassungsmittel (20) ermittelt wird, aus welchem mittels einer ersten Schätzfunktion ein erster Schätzwert hinsichtlich des Auftretens der Störstelle (11) der Leitung (10) bestimmt wird, und zumindest ein zweiter Indikator (41-43) durch zumindest ein, an einem zweiten Erfassungsort (31-33) zugeordnetes, zweites Erfassungsmittel (21-23) ermittelt wird, aus welchem mittels zumindest einer zweiten Schätzfunktion hinsichtlich des Auftretens der Störstelle (11) der Leitung (10) zumindest ein zweiter Schätzwert bestimmt wird, und aus dem ersten Schätzwert und dem zumindest einen zweiten Schätzwert mittels einer Gesamt-Schätzfunktion ein Gesamt-Schätzwert unter Berücksichtigung der jeweiligen Lage des ersten Erfassungsortes (30) und des zweiten Erfassungsortes (31-33) bestimmt wird, aus welchem das Auftreten der Störstelle (11) abgeschätzt wird.
(EN)
The invention relates to identifying the occurrence of a defect (11) in a pipeline (10) by means of estimation, wherein at least one first indicator (40) is identified by a first detection means (20) assigned to a first detection location (30), from which indicator a first estimation value regarding the occurrence of the defect (11) in the pipeline (10) is determined by means of a first estimation function, and at least one second indicator (41-43) is identified by at least one second detection means (21-23) assigned to a second detection location (31-33), from which indicator at least one second estimation value regarding the occurrence of the defect (11) in the pipeline (10) is determined by means of at least one second estimation function, and an overall estimation value is determined from the first estimation value and the at least one second estimation value by means of an overall estimation function by taking into account the respective positions of the first detection location (30) and of the second detection location (31-33), from which overall estimation value the occurrence of the defect (11) is estimated.

L'invention concerne un procédé pour déterminer l'apparition d'un point de défaut (11) d'une ligne (10) au moyen d'une estimation. Selon l'invention, au moins un premier indicateur (40) est identifié par un premier moyen de détection (20) associé à un premier endroit de détection (30), à partir duquel une première valeur estimée concernant l'apparition du point de défaut (11) de la ligne (10) est déterminée au moyen d'une première fonction d'estimation, et au moins un deuxième indicateur (41-43) est identifié par au moins un deuxième moyens de détection (21-23) associé à un deuxième endroit de détection (31-33), à partir duquel au moins une deuxième valeur estimée concernant l'apparition du point de défaut (11) de la ligne (10) est déterminée au moyen d'au moins une deuxième fonction d'estimation puis, à partir de la première valeur estimée et de ladite deuxième valeur estimée, une valeur estimée globale est déterminée au moyen d'une fonction d'estimation globale en tenant compte de la position respective du premier endroit de détection (30) et du deuxième endroit de détection (31-33), l'apparition du point de défaut (11) étant alors estimée à partir de celle-ci.
