Abstract

Die Erfindung betrifft ein Verfahren zur Optimierung der Gleisoberbauinstandhaltung mit den Schritten Identifizieren (501) von im Gleis vorkommenden und bei Gleisvermessungen hervortretenden Einzelfehlertypen, Ermitteln (501) von Referenzmessungen für jeden dieser Einzelfehlertypen, Anlegen (501) von Datensätzen bestehend aus jeweils einer Referenzmessung in Form eines Messdatenvektors sowie deren zugeordneter Einzelfehlertyp in einer Datenbank (502) für bekannte Einzelfehlertypen, Trainieren eines Klassifikators (505) mit den angelegten Datensätzen, Klassifizieren von neuen Messdaten (503, 504) eines Einzelfehlers anhand der angelegten Datensätze durch den Klassifikator (505) und Entscheiden (506) über Instandhaltungsmaßnahmen bezogen auf den Einzelfehler zumindest teilweise basierend auf der Klassifizierung der Messdaten (503, 504) des Einzelfehlers. Die Erfindung bezieht sich ferner auf eine entsprechende Datenbank (502) zur Optimierung der Gleisoberbauinstandhaltung.

The invention relates to a method for optimizing the track superstructure maintenance with the steps of identifying (501) single fault types occurring in the track and emerging in track surveys, determining (501) reference measurements for each of these single fault types, applying (501) data sets each consisting of a reference measurement in the form a measurement data vector and its associated single error type in a database (502) for known single error types, training a classifier (505) with the applied data sets, classifying new measurement data (503, 504) of a single error based on the created data sets by the classifier (505) and deciding (506) via maintenance measures related to the single error based at least in part on the classification of the measurement data (503, 504) of the individual error. The invention further relates to a corresponding database (502) for optimizing track superstructure maintenance.
