Abstract

A method for generating switching signals on a railway rail as a function of its bending under the weight of the wheels, or of the railway goods wagon, rolling over it is described. These signals are independent of the travel speed and symmetrical with respect to the wheel set. For this purpose, the bending of the rail as a function of its loading is continuously measured, a change in the loading of the rail being deduced from the deformation of the rail. The electrical signal which is generated by the deformation represents the time of a rail vehicle approaching, travelling over and travelling away, the maximum of the variation in the signal permitting the wheel position to be determined exactly. It is also proposed to use the method at at least two points of a rail so that the exact wheel speed can be determined continuously from axle to axle. As a device for carrying out the method, it is proposed to attach strain gauges (DMS), preferably to the stem of the rail, and thus to tap off an electrical signal which is proportional to the bending of the rail. The strain gauge or gauges can be permanently attached to the rail, for example welded on or even connected to the said rail by means of a bolt connection, by means of a carrier plate. An evaluation unit from which a freely selectable number of individual signals can be obtained is connected downstream of the strain gauge, it being possible for the selection of the said individual signals to be respecified even from axle to axle. <IMAGE>

Description

Die Erfindung betrifft ein Verfahren zur Erzeugung von elektrischen Signalen an Eisenbahnschienen, die durch die Räder von Schienenfahrzeugen ausgelöst werden, und die zur Steuerung von technischen Einrichtungen am Gleis und/oder an schienengleichen Bahnübergängen und/oder in Stellwerken benötigt werden, oder die in technischen Einrichtungen zu Zwecken der Zählung und/oder Schaltung und/oder Meßtorbildung und/oder zur Bestimmung der physikalischen Eigenschaften des Rades und/oder des Radsatzes und/oder des Drehgestelles und oder des Fahrzeuges, von dem das Gleis gerade befahren wird, Verwendung finden; sowie eine Einrichtung zur Durchführung des Verfahrens.The invention relates to a method for generating electrical signals on railroad tracks, which are triggered by the wheels of rail vehicles, and which are required for the control of technical equipment on the track and / or at level railroad crossings and / or in signal boxes, or in technical equipment are used for the purposes of counting and / or switching and / or measuring gates and / or for determining the physical properties of the wheel and / or the wheelset and / or the bogie and / or the vehicle from which the track is currently being driven; and a device for performing the method.

Zu diesen Zwecken ist es bekannt, daß bei der Mehrzahl aller Bahnverwaltungen Systeme und Verfahren, basierend auf mechanischen, magnetischen oder elektromagnetischen Prizipien, als radbedientes Schaltmittel, in großen Stückzahlen eingesetzt werden.For these purposes it is known that systems and methods based on mechanical, magnetic or electromagnetic principles, as wheel-operated switching means, are used in large numbers in the majority of all railway administrations.

Alle bekannten Verfahren haben gravierende Nachteile bezüglich ihres geschwindigkeitsabhängigen Schaltverhaltens, der mechanischen und/oder elektrischen Beeinflußbarkeit und der zum Teil aufwendigen Montage und elektrischen und mechanischen Justage an der Schiene.
So arbeiten z.B. mechanische Systeme nur bei relativ niedrigen Zuggeschwindigkeiten zuverlässig.
Schienenkontakte mit Permanentmagneten können an elektrifizierten Strecken durch die starken elektromagnetischen Felder der Lokomotivantriebe entmagnetisiert und damit zerstört werden.
Nach elektromagnetischen Prinzipien arbeitende Systeme können durch elektrische Felder, Triebrückströme und Wirbelströme stark beeinflußt und ggf. funktionsunfähig gemacht werden.All known methods have serious disadvantages with regard to their speed-dependent switching behavior, the mechanical and / or electrical influenceability and the sometimes complex assembly and electrical and mechanical adjustment on the rail.
For example, mechanical systems only work reliably at relatively low train speeds.
Rail contacts with permanent magnets can be demagnetized on electrified lines by the strong electromagnetic fields of the locomotive drives and thus destroyed.
Systems operating according to electromagnetic principles can be strongly influenced by electrical fields, drive reverse currents and eddy currents and possibly rendered inoperable.

Optische Einrichtungen werden durch ständige Verschmutzung durch den Zugbetrieb und die Beeinflussung durch witterungsbedingte Einflüsse, z.B. Nebel und Schneefall, immer wieder unbrauchbar gemacht.
Ferner ist es bei diesen Verfahren auch nachteilig, daß die elektrischen und/oder mechanischen Funktionseinheiten immer wieder nachjustiert oder nachgeeicht werden müssen, was bei einigen Systemen nur bei bestimmten Außentemperaturen erfolgreich durchgeführt werden kann.Optical devices are made unusable again and again due to constant contamination by train operation and the influence of weather-related influences, such as fog and snowfall.
Furthermore, it is also disadvantageous in these methods that the electrical and / or mechanical functional units have to be readjusted or re-calibrated again and again, which in some systems can only be successfully carried out at certain outside temperatures.

Der Erfindung liegt die Aufgabe zugrunde, diese Nachteile zu überwinden und ein Meßverfahren und eine Einrichtung zu dessen Durchführung anzugeben, das ausschließlich auf die physikalischen Einwirkungen der Räder von Eisenbahnfahrzeugen auf die Fahrschienen anspricht und hierbei Signale erzeugt, die im wesentlichen nur von der durch das Rad erzeugten Schienenverformung abhängen.
Dieses Verfahren schafft die Möglichkeit der Realisierung von geschwindigkeitsunabhängigen und achssymmetrischen Meßsignalen, wie sie in den oben genannten Einsatzfällen im allgemeinen und bei stationären Radsatz-Meßanlagen am Gleis, wie z.B. zur Messung von Radsatzlager- und Radreifentemperaturen, Radflachstellen, Radgewicht, Radprofil, Profil- und Geschwindigkeitüberwachungsanlagen im speziellen unbedingt erforderlich sind.The invention has for its object to overcome these disadvantages and to provide a measuring method and a device for its implementation, which responds exclusively to the physical effects of the wheels of rail vehicles on the rails and generates signals that are essentially only those of the wheel depend on the generated rail deformation.
This method creates the possibility of realizing speed-independent and axially symmetrical measurement signals, such as those in general in the above-mentioned applications and in stationary wheel set measuring systems on the track, such as for measuring wheel set bearing and wheel tire temperatures, wheel flat points, wheel weight, wheel profile, profile and Speed monitoring systems in particular are absolutely necessary.

Diese Aufgabe wird durch ein Verfahren gelöst, das die in Anspruch 1 genannten Merkmale aufweist. Diese sehen vor: die durch die Radsatzlast erzeugte Durchbiegung der Schiene mittels eines an mindestens einer Schiene befestigten DMS-Systems zu messen, das in Höhe der Schienenschwerlinie am Schienensteg angebracht ist.
Die Anbringung dieses Systems in Höhe der Schienenschwerlinie ermöglicht eine von den Schub- und Zugspannungen in der Schiene, wie sie als Folge von deren Durchbiegung auftreten, unabhängige Erfassung der elastischen Schienenverformung.This object is achieved by a method which has the features mentioned in claim 1. These provide: To measure the deflection of the rail caused by the axle load by means of a strain gauge system attached to at least one rail, which is attached to the rail web at the level of the rail's center of gravity.
The installation of this system at the level of the rail's center of gravity enables the elastic rail deformation to be recorded independently of the shear and tensile stresses in the rail as a result of its deflection.

Durch diesen Aufbau wird somit eine Abhängigkeit des Schaltsignals von der Auflage der Schiene auf der Schwelle erreicht. Das auf diese Weise gewonnene Signal steigt bei Annäherung des Rades an die beschriebene Einrichtung kontinuierlich an und erreicht sein Maximum direkt über dem erfindungsgemäßen Systemaufbau. Aus dem Signalverlauf kann direkt auf die Radposition geschlossen werden.With this structure, a dependence of the switching signal on the support of the rail on the threshold is achieved. The signal obtained in this way rises continuously as the wheel approaches the device described and reaches its maximum directly above the system structure according to the invention. The wheel position can be deduced directly from the signal curve.

a possible way of interconnecting different measuring points and feeding the signals into an electronic computer system.

In Fig.1 sind mit 1 vier Schienen im Querschnitt gezeigt, an welche die DMS-Systeme 4b, 5b auf unterschiedliche Arten angebracht sind. Und zwar in der Zeichnung von links nach rechts mit einer Schweißverbindung, mit einer Schraubverbindung durch eine Schienenstegschraube 3, mit aufgeschweißter DMS-Trägerplatte 2, und mit einer aufgeschraubten DMS-Trägerplatte 2, die zwischen Schienenfuß und Schienenkopf eingespannt ist.In FIG. 1, four rails are shown with 1 in cross-section, to which the strain gauge systems 4b, 5b are attached in different ways. Namely in the drawing from left to right with a welded connection, with a screw connection by means of a rail bar screw 3, with a welded-on strain gauge support plate 2, and with a screwed-on strain gauge support plate 2, which is clamped between the rail foot and the rail head.

Wie aus der Seitenansicht der Fig.2 mit den drei Querschnittsdarstellungan A, B, C erkennbar, können auf einer Trägerplatte 2 mehrere DMS-Systeme angebracht sein, die dann mit 4b bzw. 5b bezeichnet sind.As can be seen from the side view of FIG. 2 with the three cross-sectional views at A, B, C, a plurality of strain gauge systems can be mounted on a carrier plate 2, which are then designated 4b and 5b, respectively.

Die Signale werden von den DMS-Systemen 4b, 5b zu einem Kabelverteiler 6 geleitet, an den ein Anschlußkabel 7 angeklemmt ist, das die Verbindung zu einem Elektronik-Kabelverteiler 30 (Fig.3) herstellt.The signals are passed from the strain gauge systems 4b, 5b to a cable distributor 6, to which a connecting cable 7 is connected, which establishes the connection to an electronic cable distributor 30 (FIG. 3).

Aus Fig.4 ist ersichtlich, daß mehrere Verteiler 30 hintereinander geschaltet in einer Zuleitung zu einer elektronischen Auswerteeinheit liegen können.It can be seen from FIG. 4 that a plurality of distributors 30 can be connected in series in a feed line to an electronic evaluation unit.

Wie Fig.3 zeigt, können mehrere Doppel-DMS-Systeme an den Schienen 1 angebracht sein, und zwar entweder innerhalb eines Schwellenfaches 1a einander gegenüberliegend an beiden Schienen je ein System 25, 26, oder an der gleichen Schiene als hintereinander in verschiedenen Schwellenfächern liegende Systeme 27,28.As shown in FIG. 3, a plurality of double strain gauge systems can be attached to the rails 1, either within a sleeper compartment 1a opposite each other on both rails, one system 25, 26, or on the same rail as one behind the other in different sleeper compartments Systems 27.28.

Durch letztere Anordnung von zwei in Fahrtrichtung des Zuges hintereiander an der Schiene 1 liegende Systeme 27, 28 wird die genaue von Bremsungen und Beschleunigungen unabhängige Erfassung der Zuggeschwindigkeit und die Steuerung eines den Systemen nachgeordneten, nicht dargestellten Taktgenerators in der elektronischen Auswerteeinheit 40 ermöglicht, wodurch eine geschwindigkeitsunabhängige Schaltlänge erreicht wird.The latter arrangement of two systems 27, 28 lying one behind the other in the direction of travel of the train on the rail 1 enables precise detection of the train speed independent of braking and accelerations and the control of a clock generator (not shown) downstream of the systems in the electronic evaluation unit 40, thereby enabling a speed-independent switching length is reached.

Durch die Verschaltung jeweils zweier DMS 4b, 5b zu einer Meßbrücke wird eine höhere Schaltsicherheit und Genauigkeit gewährleistet.The interconnection of two strain gauges 4b, 5b to form a measuring bridge ensures higher switching reliability and accuracy.

Das erfindungsgemäße Verfahren und die zu seiner Durchführung vorgeschlagene Einrichtung kann wegen seiner unbedeutenden elektrischen Beeinflußbarkeit an Eisenbahntrassen mit allen bekannten Oberbauformen und vorzugsweise an Strecken mit elektrischer Zugförderung eingesetzt werden.The inventive method and the proposed device for its implementation can be used because of its insignificant electrical influence on railway lines with all known superstructures and preferably on routes with electrical train.

  • Geschwindigkeitsbereichen von 1 km/h - 500 km/h,
  • Radlastbereichen von 1 t - max. zulässige Radlast,
