Abstract

Um ein Verfahren zum Detektieren von Schmierfilm auf Schienen zu schaffen, das witterungsunabhängig das Vorhandensein der den Schmierfilm bildenden unterschiedlichen Substanzen auf der Schiene erkennt, so daß eine gezielte Reinigung der Fahrfläche der Schienen, d.h. Entfernen des Schmierfilms, vorgenommen werden kann, bevor es zu den beschriebenen Störungen kommt, wird ein von einem Laser (6) entsandter über die Schienenoberfläche reflektierter Laserstrahl (5) von einem Detektor (12) in spiegelnder Reflexion und von einem zweiten Detektor (13) in diffuser Reflexion empfangen, wobei die Signale von einer Auswerteeinheit (16) ausgewertet und zur Auswertung die Einzelsignale beider Detektoren (12, 13) sowie das Summensignal und die Signalverhältnisse herangezogen werden.

Figure 00000001
In order to create a method for detecting lubricating film on rails, which detects the presence of the different substances forming the lubricating film on the rail, regardless of the weather, so that a targeted cleaning of the running surface of the rails, ie removal of the lubricating film, can be carried out before it reaches the described interference occurs, a laser beam (5) emitted by a laser (6) reflected over the rail surface is received by a detector (12) in specular reflection and by a second detector (13) in diffuse reflection, the signals being transmitted by an evaluation unit ( 16) are evaluated and the individual signals of both detectors (12, 13) as well as the sum signal and the signal ratios are used for the evaluation.
