Description

Die Erfindung betrifft ein Verfahren zum Unterstopfen eines Gleises, wobei dieses vorerst unabhängig von einer Stopfmaschine durch Erfassen einer Anzahl von Gleisparameter vermessen wird, die ermittelten Istlagedaten in einem Softwareprogramm ausgewertet und schließlich als Solllagedaten zur Steuerung der Stopfmaschine für eine Optimierung der Gleislage verwendet werden.The invention relates to a method for submerging a track, wherein this is initially measured independently of a tamping machine by detecting a number of track parameters, evaluated the determined actual data in a software program and finally used as a target position data for controlling the tamping machine for optimizing the track position.

In einem durch US 6 311 624 bekannten Verfahren zum Unterstopfen eines Gleises werden in einer ersten Maschinenvorfahrt Relativverschiebungen zwischen zwei Mess-Bezugspunkten unter Bildung einer Ist-Lagekurve des Gleises registriert. Anschließend wird aus der Ist-Lagekurve unter Bildung von Korrekturwerten eine Soll-Lagekurve des Gleises errechnet. In einer zweiten Maschinenvorfahrt erfolgt unter Registrierung der Relativverschiebungen zwischen den beiden Mess-Bezugspunkten entsprechend den ermittelten Korrekturwerten eine Anhebung und Unterstopfung des Gleises in die Soll-Lage.In a through US 6,311,624 known methods for undercutting a track relative displacements between two measuring reference points are registered in a first machine approach to form an actual position curve of the track. Subsequently, a desired position curve of the track is calculated from the actual position curve with the formation of correction values. In a second machine approach, registration of the relative displacements between the two measurement reference points in accordance with the determined correction values results in an increase and a clogging of the track into the desired position.

EP 0 520 342 A1 offenbart ein Messfahrzeug zur Ermittlung der Gleis-Ist-Lage in Bezug auf die Gleis-Soll-Lage. Diesem ist ein unabhängig verfahrbarer Satellitenwagen zugeordnet. Korrekturwerte werden per Funk an eine Stopfmaschine übertragen und dort zur Steuerung eines Gleishebe- und Richtaggregates verarbeitet. EP 0 520 342 A1 discloses a measuring vehicle for determining the actual track position with respect to the track setpoint position. This is associated with an independently movable satellite car. Correction values are transmitted by radio to a tamping machine where they are processed to control a track lifting and leveling unit.

Aus WO 2005/098352 A1 ist ein Verfahren sowie eine Vorrichtung zur Erfassung des Zustandes von Gleisanlagen besonders von Weichen bekannt. Dabei werden Ist-Profildaten mit Söll-Profildaten verglichen.Out WO 2005/098352 A1 is a method and apparatus for detecting the condition of track systems especially known turnouts. This compares actual profile data with Söll profile data.

Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung eines Verfahrens der eingangs genannten Art, mit dem eine vereinfachte Unterstopfung eines Gleises möglich ist.The object of the present invention is now to provide a method of the type mentioned, with a simplified Unterstopfung a track is possible.

Diese Aufgabe wird erfindungsgemäß mit einem Verfahren der gattungsgemäßen Art dadurch gelöst, dass für eine übereinstimmende Zuordnung der Solllagedaten zu von der Stopfmaschine während der Gleisunterstopfung ermittelten Istlagedaten eine Ortssynchronisation hinsichtlich mindestens eines Gleisparameters durchgeführt wird.This object is achieved with a method of the generic type in that for a matching assignment of the target position data to determined by the tamping machine during track submission actual position data, a location synchronization is performed with respect to at least one track parameter.

Mit dieser Datenübertragung erübrigt sich in vorteilhafter Weise eine eigene Messfahrt der Stopfmaschine, so dass die Stopfarbeiten rascher beendet werden können. Unter Zuhilfenahme beispielsweise der Daten für die Spurweitenmessung ist eine problemlose und genaue Ortssynchronisation der von einem Messfahrzeug ermittelten Daten mit den durch die Stopfmaschine erfassten Istlagedaten des Gleises möglich.With this data transfer, a separate measuring run of the tamping machine is advantageously unnecessary, so that the tamping work can be completed more quickly. With the aid of, for example, the data for measuring the gauges, a problem-free and accurate spatial synchronization of the data determined by a measuring vehicle with the actual position data of the track detected by the tamping machine is possible.

Weitere Vorteile der Erfindung ergeben sich aus dem Unteranspruch und der Zeichnungsbeschreibung.Further advantages of the invention will become apparent from the dependent claim and the drawing description.

Im Folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher beschrieben. Es zeigen: Fig. 1 eine Seitenansicht einer Stopfmaschine, Fig. 2 und 3 Messdaten einer Spurweite des Gleises vor bzw. nach einer Ortssynchronisation.In the following the invention will be described with reference to an embodiment shown in the drawing. Show it: Fig. 1 a side view of a stuffing machine, FIGS. 2 and 3 Measurement data of a track gauge of the track before or after a local synchronization.

Eine in Fig. 1 dargestellte Stopfmaschine 1 weist einen auf Schienenfahrwerken 2 abgestützten Maschinenrahmen 3 auf und ist durch einen Fahrantrieb 4 auf einem aus Schwellen und Schienen 5 gebildeten Gleis 6 verfahrbar. Zur Durchführung von Gleisstopfarbeiten sind durch Antriebe 7 höhenverstellbare Stopfaggregate 8 sowie ein Hebe- und Richtaggregat 9 vorgesehen. In einer Fahr- bzw. Arbeitskabine 10 befindet sich eine zentrale Rechen- und Speichereinheit 11 zur Verarbeitung von Gleisdaten.An in Fig. 1 Tamping machine 1 shown has a supported on rail chassis 2 machine frame 3 and is moved by a traction drive 4 on a track 6 formed of sleepers and rails 5. To perform Tamping works 7 height adjustable tamping units 8 and a lifting and straightening unit 9 are provided by drives. In a driving or working cabin 10 is a central computing and storage unit 11 for processing track data.

Zur Erfassung von Gleislagefehlern ist ein Gleislage-Messsystem 12 vorgesehen, das im Wesentlichen aus einem Lasersender 13, einer durch einen Lichtstrahl gebildeten Messlinie 14, einem Empfänger 15 und einer Steuereinheit 16 gebildet ist. Die Messlinie 14 wird durch einen mit dem Austritt des Lichtstrahls gebildeten ersten Mess-Bezugspunkt und einem zweiten, durch den Kontakt mit dem Empfänger 15 bestimmten zweiten Mess-Bezugspunkt festgelegt.To detect track position errors, a track position measuring system 12 is provided, which is essentially formed by a laser transmitter 13, a measuring line 14 formed by a light beam, a receiver 15 and a control unit 16. The measuring line 14 is defined by a first measuring reference point formed with the exit of the light beam and a second second measuring reference point determined by the contact with the receiver 15.

Im Folgenden wird der bisher aus dem Stand der Technik bekannte und übliche Verfahrensablauf zur Erfassung der Gleislagedaten näher beschrieben. Nach Überfahren des zu korrigierenden Gleisabschnittes wird ein Vorwagen 17 von der Maschine 1 gelöst und auf das Gleis 6 abgesetzt. Anschließend erfolgt eine Rückfahrt der Maschine 1 entgegen der durch einen Pfeil 18 dargestellten Arbeitsrichtung, bis die Maschine 1 auf einem nicht mehr zu korrigierenden Gleisabschnitt zu stehen kommt. Ein dem Stopfaggregat 8 unmittelbar vorgeordnetes Tastorgan wird auf das Gleis 6 abgesetzt und gegen eine als Bezugsstrang dienende Schiene 5 gedrückt. Anschließend wird der Lasersender 13 vorzugsweise auf das Zentrum des Empfängers 15 angepeilt und in seiner Lage gegenüber dem Vorwagen 17 fixiert.In the following, the procedure known from the prior art and usual procedure for detecting the track position data is described in more detail. After passing over the track section to be corrected, a preamble 17 is released from the machine 1 and placed on the track 6. Subsequently, a Return of the machine 1 opposite to the working direction shown by an arrow 18 until the machine 1 comes to rest on a track section no longer to be corrected. A tamping device 8 directly upstream of the tamping unit is deposited on the track 6 and pressed against a rail 5 serving as a reference strand. Subsequently, the laser transmitter 13 is preferably aimed at the center of the receiver 15 and fixed in its position relative to the pre-carriage 17.

Bei der nun beginnenden Messfahrt der Maschine 1 in Richtung zum Vorwagen 17 kommt es entsprechend den Gleislagefehlern zu Relativverschiebungen zwischen der stationären Messlinie 14 und dem Empfänger 15. Diese Relativverschiebungen werden in der Rechen- und Speichereinheit 13 in Verbindung mit einer Wegmessung durch eine Wegmesseinrichtung gespeichert. Während die Stopfmaschine 1 wiederum zum Anfang des zu korrigierenden Gleisabschnittes zurückgefahren wird, erfolgt durch die Recheneinheit 11 unter Zugrundelegung der gemessenen Ist-Lagekurve die Bildung einer Soll-Lagekurve sowie die Ermittlung der entsprechenden Korrekturwerte. Anschließend startet die Arbeitsvorfahrt zur Gleislagekorrektur.In the case of the now commencing measuring travel of the machine 1 in the direction of the preamble 17, relative displacements between the stationary measuring line 14 and the receiver 15 occur in accordance with the track position errors. These relative displacements are stored in the arithmetic and storage unit 13 in conjunction with a distance measurement by a displacement measuring device. While the stuffing machine 1 in turn is moved back to the beginning of the track section to be corrected, the calculation unit 11 uses the measured actual position curve to form a desired position curve and to determine the corresponding correction values. Subsequently, the working approach to the track position correction starts.

Im Vergleich zu diesem bekannten Verfahren ist durch das im Folgenden beschriebene erfindungsgemäße Verfahren eine Vereinfachung der Gleisunterstopfung erzielbar.Compared to this known method, a simplification of the track clogging can be achieved by the method according to the invention described below.

Gleise werden generell in regelmäßigen Abständen mithilfe eines speziellen Messfahrzeuges befahren, um dabei verschiedenste Gleisparameter zu erfassen. Die abgespeicherten Daten werden automatisch hinsichtlich ihrer Abweichung von Solldaten analysiert und dienen schließlich als Grundlage für eventuell durchzuführende Gleislagekorrekturarbeiten.Tracks are generally used at regular intervals with the aid of a special measuring vehicle in order to record a wide variety of track parameters. The stored data are automatically analyzed with respect to their deviation from target data and serve eventually as a basis for any track position correction work to be performed.

Mit dem erfindungsgemäßen Verfahren ist es nunmehr möglich, die nach einem Analyseverfahren ermittelten, ursprünglich vom Messfahrzeug kommenden Daten als Solllagedaten des Gleises auf die Recheneinheit 11 der Stopfmaschine 1 zu übertragen. Für eine sinnvolle Datenzuordnung muss allerdings durch eine geeignete Software eine Ortssynchronisation durchgeführt werden, so dass schließlich die übernommenen Daten örtlich mit den durch die Stopfmaschine erfassten Istlagedaten des Gleises übereinstimmen.With the method according to the invention, it is now possible to transfer the data, originally determined by the measuring vehicle, determined by an analysis method to the arithmetic unit 11 of the tamping machine 1 as setpoint position data of the track. For a meaningful data allocation, however, a location synchronization must be carried out by suitable software, so that finally the acquired data coincide locally with the actual position data of the track detected by the tamping machine.

Die Ortssynchronisation erfolgt unter Zuhilfenahme eines geeigneten, quasi als Fingerabdruck des Gleises wirksamen Gleisparameters. Im dargestellten Beispiel gemäß Fig. 2 und 3 ist dies einerseits die als punktierte Linie dargestellte, durch das Messfahrzeug erfasste Spurweite des Gleises 6 und andererseits die durch die Stopfmaschine 1 ermittelte, als volle Linie dargestellte Spurweite. Es sind jedoch auch andere Gleisparameter, wie z.B. Längshöhe des Gleises, aber auch Messdaten der Fahrleitung, für eine Ortssynchronisation verwendbar.The location synchronization takes place with the aid of a suitable track parameter, which effectively acts as a fingerprint of the track. In the example shown according to FIGS. 2 and 3 On the one hand, this is the gauge of the track 6, shown as a dotted line, detected by the measuring vehicle and, on the other hand, the track width determined by the tamping machine 1 and shown as a full line. However, other track parameters, such as longitudinal height of the track, but also measurement data of the catenary, can be used for a location synchronization.

Zur Ortssynchronisation der Daten stehen grundsätzlich verschiedene mathematische Methoden zur Verfügung. Mittels Kovarianzen bzw. dem Minimumverfahren (berechnet wird hier die Summe der Quadrat-Differenzabweichungen von zwei Signalen oder auch die Summe der Absolut-Differenzabweichungen von zwei Signalen) ist es möglich unterschiedliche Messsignale (verschiedene Messzeitpunkte, verschiedene Datenquellen) zu synchronisieren.For the spatial synchronization of the data, various mathematical methods are available. Using covariances or the minimum method (Calculated here is the sum of the square difference deviations of two signals or the sum of the absolute difference deviations of two signals), it is possible to synchronize different measurement signals (different measurement times, different data sources).

Nach erfolgter Ortssynchronisation werden die in die Rechen- und Speichereinheit 11 eingespeisten Solllagedaten mit den von der Stopfmaschine gemessenen Istlagedaten verglichen und aus der Differenz resultierende Korrekturwerte zur Steuerung der Stopfmaschine bzw. deren Gleishebe- und Richtaggregate für die Gleisunterstopfung verwendet. Damit erübrigt sich eine zum Stand der Technik beschriebene gesonderte Meßfahrt der Stopfmaschine unmittelbar vor der Gleisstopfung.After the location synchronization, the setpoint position data fed into the arithmetic and storage unit 11 are compared with the actual position data measured by the stuffing machine, and correction values resulting from the difference are used to control the stuffing machine or its track lifting and leveling units for the track sub-stuffing. Thus, a separate measuring travel of the tamping machine described prior to the prior art is unnecessary immediately before the Gleisstippung.
