Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Ermittlung des Abstandes zwischen einem ein Messsystem tragenden und einem benachbarten und im gleichen Gleis befindlichen Eisenbahnfahrzeug.The invention relates to a method and a device for determining the distance between a measuring system carrying a system and an adjacent railroad vehicle located in the same track.

Zwei Schienen eines Gleises eines als isolierfähig angenommenen Oberbaus werden sowohl von einer ersten Achse einer Lokomotive als auch von einer letzen Achse eines Zielwagens kurzgeschlossen. Diese Elemente bilden eine rechteckförmige elektrische Leiterschleife, deren Breite der Spurweite des Gleises und deren Länge dem Abstand der beiden Achsen voneinander entspricht.Two rails of a track of a superstructure assumed to be capable of being insulated are short-circuited both by a first axle of a locomotive and by a last axle of a target car. These elements form a rectangular electrical conductor loop whose width corresponds to the gauge of the track and whose length corresponds to the distance between the two axes.

Zur Erfassung elektrischer Eigenschaften der rechteckförmigen Leiterschleife wird an der Lokomotive eine Koppelspule angeordnet. Die Koppelspule und die rechteckförmige elektrische Leiterschleife, die aus den beiden Gleisen und den beiden Achsen gebildet wird, wirken als stark streuender Transformator. Die Primärseite dieses Transformators wird aus der Koppelspule, die Sekundärseite aus der rechteckförmigen elektrischen Leiterschleife gebildet. Einem Strom in der Koppelspule ist somit einem magnetischen Fluss zuzuordnen, der aufgrund der Flussverkettung auch durch die aus Oberbau und Achsen gebildete Leiterschleife tritt. Damit beeinflusst der zu ermittelnde Abstand der Fahrzeuge auch die elektrischen Eigenschaften der Koppelspule, die einer auf der Lokomotive angeordnete Auswerteeinrichtung als Eingangsgröße zugeführt und ausgewertet werden.

Figure imgaf001
For detecting electrical properties of the rectangular conductor loop, a coupling coil is arranged on the locomotive. The coupling coil and the rectangular electrical conductor loop, which is formed from the two tracks and the two axes, act as a strong scattering transformer. The primary side of this transformer is formed from the coupling coil, the secondary side of the rectangular electrical conductor loop. A current in the coupling coil is thus assigned to a magnetic flux, which also occurs due to the flux linkage through the conductor loop formed from the superstructure and axes. Thus, the distance to be determined of the vehicles also influences the electrical properties of the coupling coil, which are fed to and evaluated by an evaluation device arranged on the locomotive as an input variable.
