Description

In rangiertechnischen Ablaufanlagen, die auch als Zugbildungsanlagen bezeichnet werden, werden Zerlegeeinheiten in Form von zu zerlegenden Güterzügen von einer Abdrücklokomotive über einen Ablaufberg abgedrückt. Hierbei werden Abläufe in Form von Wagen oder Wagengruppen unter Nutzung der auf die Abläufe wirkenden Schwerkraft aus einem Berggleis in unterschiedliche Richtungsgleise sortiert. Ein eine weitgehende Automatisierung des Betriebs von Ablaufanlagen ermöglichendes automatisches Steuerungssystem ist beispielsweise aus der Firmenveröffentlichung " Automatisierungssystem für Zugbildungsanlagen Trackguard Cargo MSR32 - Mehr Effizienz und Sicherheit im Güterverkehr", Bestell-Nr.: A19100-V100-B898-V2, Siemens AG 2012 , bekannt.In shunting systems, which are also referred to as train formation systems, dismantling units in the form of freight trains to be dismantled are pushed over a drainage hill by a push-off locomotive. Here, processes in the form of wagons or groups of wagons are sorted from a mountain track into different directional tracks using the force of gravity acting on the processes. An automatic control system that enables extensive automation of the operation of process plants is, for example, from the company publication " Automation system for train formation systems Trackguard Cargo MSR32 - More efficiency and safety in freight traffic ", order no .: A19100-V100-B898-V2, Siemens AG 2012 , known.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Betreiben einer rangiertechnischen Ablaufanlage anzugeben, durch das die Leistungsfähigkeit der Ablaufanlage erhöht wird.The present invention is based on the object of specifying a method for operating a shunting drainage system by means of which the performance of the drainage system is increased.

Diese Aufgabe wird erfindungsgemäß gelöst durch ein Verfahren zum Betreiben einer rangiertechnischen Ablaufanlage, wobei durch eine Steuereinrichtung der Ablaufanlage für eine erste Zerlegeeinheit, die im Rahmen eines ersten Abdrückvorgangs über einen Ablaufberg der Ablaufanlage abzudrücken ist, ein Beendigungszeitpunkt des ersten Abdrückvorgangs prognostiziert wird, für eine zweite Zerlegeeinheit, die von einer Abdrücklokomotive im Rahmen eines Anrückvorgangs in Richtung des Ablaufberges zu schieben und im Rahmen eines auf den ersten Abdrückvorgang folgenden zweiten Abdrückvorgangs über den Ablaufberg abzudrücken ist, unter Berücksichtigung zumindest des prognostizierten Beendigungszeitpunkts des ersten Abdrückvorgangs sowie einer aktuellen Position der zweiten Zerlegeeinheit ein Geschwindigkeitsverlauf bestimmt wird, gemäß dem ein unterbrechungsfreier Übergang des Anrückvorgangs in den zweiten Abdrückvorgang erfolgt, und die Abdrücklokomotive gemäß dem bestimmten Geschwindigkeitsverlauf gesteuert wird.According to the invention, this object is achieved by a method for operating a shunting drainage system, wherein a control device of the drainage system for a first dismantling unit, which is to be pressed over a drainage mountain of the drainage system as part of a first pressure test, predicts a termination time of the first pressure release process, for a second A dismantling unit that is to be pushed by a push-off locomotive in the direction of the discharge mountain as part of a push-off operation and to be pushed over the discharge mountain as part of a second push-off operation following the first push-off operation, taking into account at least the predicted end time of the first push-off operation and a current position of the second dismantling unit Speed curve is determined according to where there is an uninterrupted transition from the approach process to the second push-off process, and the push-pull locomotive is controlled according to the specific speed profile.

Gemäß dem ersten Schritt des erfindungsgemäßen Verfahrens zum Betreiben einer rangiertechnischen Ablaufanlage wird somit durch eine Steuereinrichtung der Ablaufanlage für eine erste Zerlegeeinheit, die im Rahmen eines ersten Abdrückvorgangs über einen Ablaufberg der Ablaufanlage abzudrücken ist, ein Beendigungszeitpunkt des ersten Abdrückvorgangs prognostiziert. Dies bedeutet, dass bereits vor Abschluss des ersten Abdrückvorgangs eine Prognose dahingehend erfolgt, wann der erste Abdrückvorgang beendet sein und damit der Ablaufberg zur anderweitigen Nutzung frei sein wird. Hierbei kann die Prognose des Beendigungszeitpunkts beziehungsweise dessen Angabe sowohl absolut (d.h. beispielsweise in der Art "um 15:27:30 Uhr") als auch relativ (d.h. beispielsweise in der Art "verbleibende Restdauer 4:30 Minuten") erfolgen.According to the first step of the method according to the invention for operating a shunting drainage system, a control device of the drainage system for a first dismantling unit, which is to be pressed over a drainage mountain of the drainage system as part of a first push-off process, predicts a termination time of the first pressure-dropping process. This means that a prognosis is made as to when the first pressing process will be finished and thus the drainage mountain will be free for other use before the first pressing process is completed. The prognosis of the termination time or its specification can be made both absolutely (i.e., for example, of the type "at 3:27:30 p.m.") as well as relatively (i.e., for example, of the type "remaining time 4:30 minutes").

Gemäß dem zweiten Schritt des erfindungsgemäßen Verfahrens wird für eine zweite Zerlegeeinheit, die von einer Abdrücklokomotive im Rahmen eines Anrückvorgangs in Richtung des Ablaufberges zu schieben und im Rahmen eines auf den ersten Abdrückvorgang folgenden zweiten Abdrückvorgangs über den Ablaufberg abzudrücken ist, unter Berücksichtigung zumindest des prognostizierten Beendigungszeitpunkts des ersten Abdrückvorgangs sowie einer aktuellen Position der zweiten Zerlegeeinheit ein Geschwindigkeitsverlauf bestimmt, gemäß dem ein unterbrechungsfreier Übergang des Anrückvorgangs in den zweiten Abdrückvorgang erfolgt. Dies bedeutet, dass für die zweite Zerlegeeinheit beziehungsweise die diese in Richtung des Ablaufberges schiebende Abdrücklokomotive ein derartiger Geschwindigkeitsverlauf bestimmt wird, dass die zweite Zerlegeeinheit den Ablaufberg zu dem prognostizierten Beendigungszeitpunkt oder kurz nach diesem erreicht, so dass der Anrückvorgang planmäßig ohne Unterbrechung oder Pause in den zweiten Abdrückvorgang übergehen kann. Als Geschwindigkeitsverlauf wird hierbei im Rahmen der vorliegenden Erfindung jede Funktion bezeichnet, die bezogen auf einen gegebenen Zeitpunkt und/oder einen gegebenen Wegpunkt des Anrückvorgangs der zweiten Zerlegeeinheit unmittelbar oder mittelbar die jeweilige Geschwindigkeit der die zweite Zerlegeeinheit in Richtung des Ablaufberges schiebenden Abdrücklokomotive vorgibt.According to the second step of the method according to the invention, for a second dismantling unit, which is to be pushed by a push-off locomotive as part of an approaching process in the direction of the discharge mountain and to be pushed over the discharge mountain as part of a second push-off operation following the first push-off operation, taking into account at least the predicted termination time of the first push-off process and a current position of the second dismantling unit, a speed profile is determined according to which an uninterrupted transition from the push-off process to the second push-off process takes place. This means that for the second dismantling unit or the push-off locomotive pushing it in the direction of the discharge mountain, such a speed profile is determined that the second dismantling unit reaches the discharge mountain at the predicted termination time or shortly after this, so that the approaching process takes place as planned without interruption or pause second pressing process can skip. As a speed curve In the context of the present invention, any function is referred to which, based on a given point in time and / or a given waypoint of the approaching process of the second dismantling unit, directly or indirectly specifies the respective speed of the push-off locomotive pushing the second dismantling unit in the direction of the discharge mountain.

Gemäß dem dritten Schritt des erfindungsgemäßen Verfahrens wird die Abdrücklokomotive gemäß dem bestimmten Geschwindigkeitsverlauf gesteuert, so dass die zweite Zerlegeeinheit den Anrückvorgang in Richtung des Ablaufberges entsprechend dem bestimmten Geschwindigkeitsverlauf vornimmt. Hierdurch wird somit ein Übergang des Anrückvorgangs in den zweiten Abdrückvorgang realisiert, ohne dass es zwischen diesen beiden Vorgängen zu einer Unterbrechung oder Pause kommt. Vorzugsweise handelt es sich dabei bei dem Geschwindigkeitsverlauf dahingehend um einen "optimalen" Geschwindigkeitsverlauf, dass einerseits ein unterbrechungsfreier Übergang des Anrückvorgangs in den zweiten Abdrückvorgang erfolgt, andererseits jedoch auch ein zu spätes Eintreffen der zweiten Zerlegeeinheit am Ablaufberg vermieden wird. In diesem Fall schließt sich somit der zweite Abdrückvorgang - gegebenenfalls unter Berücksichtigung eines Sicherheitsabstands beziehungsweise von Toleranzen - unmittelbar an den ersten Abdrückvorgang an. Dies bedeutet, dass die zweite Zerlegeeinheit den Ablaufberg im Wesentlichen zum Zeitpunkt der Bergfreigabe erreicht.According to the third step of the method according to the invention, the push-off locomotive is controlled according to the specific speed profile, so that the second dismantling unit carries out the approaching process in the direction of the drainage mountain in accordance with the specific speed profile. In this way, a transition from the approaching process to the second pressing process is realized without there being an interruption or pause between these two processes. The speed profile is preferably an "optimal" speed profile in that, on the one hand, there is an uninterrupted transition from the approaching operation to the second pushing-off operation, but on the other hand, the second dismantling unit does not arrive too late at the discharge mountain. In this case, the second pressing-off process follows the first pressing-off process - possibly taking into account a safety distance or tolerances. This means that the second dismantling unit essentially reaches the discharge mountain at the time of the mountain clearance.

Das erfindungsgemäße Verfahren ist dahingehend vorteilhaft, dass es eine Erhöhung der Leistungsfähigkeit der Ablaufanlage durch eine Reduzierung von Pausen im Abdrückbetrieb ermöglicht. So werden vorbereitend zum eigentlichen Abdrückvorgang abzudrückende Zerlegeeinheiten von einer Rangier- beziehungsweise Abdrücklokomotive im Rahmen eines Anrückvorgangs in Richtung des Ablaufberges beziehungsweise des Berggleises desselben geschoben. Hierbei kann in der Praxis bislang die Situation auftreten, dass zu einem Zeitpunkt, zu dem eine jeweilige Zerlegeeinheit den Ablaufberg beziehungsweise einen Anhaltepunkt desselben erreicht, der Ablaufberg noch durch eine vorherige Zerlegeeinheit belegt beziehungsweise blockiert ist. In diesem Fall ist somit der Abdrückvorgang der vorherigen Zerlegeeinheit noch nicht abgeschlossen. Dies hat zur Folge, dass für die nachfolgende Zerlegeeinheit noch keine Bergfreigabe möglich ist und somit nach dem Anrückvorgang ein Halt der nachfolgenden Zerlegeeinheit erforderlich ist. Hierdurch entsteht eine Unterbrechung beziehungsweise Pause, die in Folge des Abbremsens und Neubeschleunigens der Zerlegeeinheit zu einer unnötigen Zeitverzögerung führt. Darüber hinaus kann für den Fall, dass die Zerlegeeinheit zu schwer für ein erneutes Anfahren der Abdrücklokomotive in der Gegensteigung ist, die Situation auftreten, dass der Anrückvorgang neu begonnen werden muss. Entsprechende Pausen und Verzögerungen können durch das erfindungsgemäße Verfahren vorteilhafterweise deutlich reduziert oder sogar nahezu vollständig vermieden werden. Dadurch, dass weiterhin ein unnötig schnelles Anrücken an den Ablaufberg mit anschließendem Bremsen, Anhalten und Wiederbeschleunigen nach Erhalt einer Berg- beziehungsweise Abdrückfreigabe vermieden wird, können sich darüber hinaus auch ein verringerter Materialverschleiß sowie reduzierte Energiekosten ergeben. Hierzu kann im Rahmen der Bestimmung des Geschwindigkeitsverlaufs insbesondere auch der Startzeitpunkt des Anrückvorgangs der zweiten Zerlegeeinheit in geeigneter Weise festgelegt beziehungsweise gewählt werden.The method according to the invention is advantageous in that it enables the performance of the drainage system to be increased by reducing the number of pauses in the press-off operation. Thus, in preparation for the actual push-off process, dismantling units to be pushed off are pushed by a shunting or push-off locomotive as part of an approaching process in the direction of the discharge mountain or the mountain track of the latter. In practice, the situation has hitherto occurred that at a point in time at which a respective dismantling unit has reached the drainage mountain or a Stopping point of the same reached, the drainage mountain is still occupied or blocked by a previous dismantling unit. In this case, the pressing process of the previous dismantling unit has not yet been completed. The consequence of this is that no mountain clearance is possible for the following dismantling unit, and it is therefore necessary for the following dismantling unit to stop after the approaching process. This creates an interruption or pause, which leads to an unnecessary time delay as a result of the braking and re-acceleration of the dismantling unit. In addition, in the event that the dismantling unit is too heavy for the push-off locomotive to start up again on the opposite slope, the situation can arise that the approaching process has to be restarted. Corresponding pauses and delays can advantageously be significantly reduced or even almost completely avoided by the method according to the invention. The fact that an unnecessarily fast approach to the drainage mountain with subsequent braking, stopping and re-acceleration after receiving a mountain or push-off release is also avoided, can also result in reduced material wear and reduced energy costs. For this purpose, in the context of determining the speed profile, in particular the start time of the approaching process of the second dismantling unit can also be specified or selected in a suitable manner.

Die vorstehend genannten Vorteile werden durch das erfindungsgemäße Verfahren vorteilhafterweise im Wesentlichen unabhängig davon realisiert, wann der Anrückvorgang der zweiten Zerlegeeinheit gestartet wird. So ergibt sich bei einem vergleichsweise frühen Start des Anrückvorgangs ein Geschwindigkeitsverlauf mit einer vergleichsweise geringen Anrückgeschwindigkeit. Sofern hingegen der Anrückvorgang - beispielsweise aus betrieblichen Gründen - vergleichsweise spät gestartet wird, ergibt sich ein Geschwindigkeitsverlauf mit einer vergleichsweise hohen Anrückgeschwindigkeit. Somit wird erfindungsgemäß - unter Berücksichtigung technischer und sicherheitstechnischer Grenzen - weitgehend unabhängig vom Startzeitpunkt des Anrückvorgangs ein unterbrechungsfreier Übergang des Anrückvorgangs in den zweiten Abdrückvorgang ermöglicht beziehungsweise gewährleistet.The above-mentioned advantages are advantageously realized by the method according to the invention essentially independently of when the approaching process of the second dismantling unit is started. With a comparatively early start of the approach process, this results in a speed profile with a comparatively low approach speed. If, on the other hand, the approaching process is started comparatively late, for example for operational reasons, the result is a speed profile with a comparatively high approaching speed. Thus, according to the invention - taking into account technical and safety-related limits - largely independent of the starting time of the approaching process, an uninterrupted transition from the approaching process to the second pushing-off process is enabled or guaranteed.

Gemäß einer besonders bevorzugten Weiterbildung des erfindungsgemäßen Verfahrens wird der Geschwindigkeitsverlauf der zweiten Zerlegeeinheit derart bestimmt, dass die zweite Zerlegeeinheit einen Anhaltepunkt des Ablaufberges zu dem prognostizierten Beendigungszeitpunkt erreicht. Üblicherweise weisen rangiertechnische Ablaufanlagen im Bereich des Ablaufberges einen Anhaltepunkt auf. Dieser gilt für die Spitze der jeweiligen Zerlegeeinheit, wobei das Erreichen des Anhaltepunktes durch die betreffende Zerlegeeinheit durch einen entsprechenden Gleiskontakt detektiert wird. Sofern der Ablaufberg zum betreffenden Zeitpunkt noch durch eine vorherige Zerlegeeinheit belegt ist und damit bezogen auf die nachfolgende Zerlegeeinheit noch keine Bergfreigabe möglich ist, ist diese somit bei Erreichen des Anhaltepunktes zum Stillstand zu bringen. Sofern nun die zweite Zerlegeeinheit den Anhaltepunkt des Ablaufberges zu dem prognostizierten Beendigungszeitpunkt erreicht, kann davon ausgegangen werden, dass der Ablaufberg zu dem gegebenen Zeitpunkt für die zweite Zerlegeeinheit gerade freigegeben wurde und damit ein unterbrechungsfreier Übergang des Anrückvorgangs in den zweiten Abdrückvorgang und gleichzeitig auch ein im Wesentlichen nahtloser Übergang von dem ersten Abdrückvorgang zu dem zweiten Abdrückvorgang erfolgt. Vorzugsweise werden jedoch auch bei dieser bevorzugten Weiterbildung des erfindungsgemäßen Verfahrens bei der Prognose des Beendigungszeitpunktes Toleranzen berücksichtigt, etwa aufgrund von Laufzeiten und Bremswegen, so dass die Bergfreigabe für die zweite Zerlegeeinheit gegebenenfalls bereits erfolgt kurz bevor diese den Anhaltepunkt erreicht.According to a particularly preferred development of the method according to the invention, the speed profile of the second dismantling unit is determined in such a way that the second dismantling unit reaches a stopping point of the discharge mountain at the predicted termination time. Shunting drainage systems usually have a stopping point in the area of the drainage hill. This applies to the tip of the respective dismantling unit, the reaching of the stopping point by the respective dismantling unit being detected by a corresponding track contact. If the discharge mountain is still occupied by a previous dismantling unit at the relevant point in time and therefore no mountain clearance is possible with respect to the subsequent dismantling unit, this must be brought to a standstill when the stopping point is reached. If the second dismantling unit now reaches the stopping point of the discharge mountain at the predicted termination time, it can be assumed that the discharge mountain has just been released for the second dismantling unit at the given point in time and thus an uninterrupted transition from the approaching process to the second push-off process and, at the same time, an im There is a substantially seamless transition from the first pressing-off process to the second pressing-off process. In this preferred development of the method according to the invention, however, tolerances are also taken into account in the forecast of the termination time, for example due to running times and braking distances, so that the mountain clearance for the second dismantling unit occurs shortly before it reaches the stopping point.

Vorzugsweise kann das erfindungsgemäße Verfahren auch derart ausgebildet sein, dass der Beendigungszeitpunkt während des ersten Abdrückvorgangs prognostiziert wird. Dies ist dahingehend vorteilhaft, dass in der Regel während des ersten Abdrückvorgangs eine genauere Prognose des Beendigungszeitpunkts als vor dem Beginn des ersten Abdrückvorgangs möglich sein wird. Gleichzeitig erlaubt eine Prognose des Beendigungszeitpunkts während des ersten Abdrückvorgangs einen zeitgerechten Anrückvorgang des zweiten Zerlegeeinheit dahingehend, dass diese zum Beendigungszeitpunkt oder kurz nach diesem den Anrückvorgang abgeschlossen und den Ablaufberg erreicht hat.The method according to the invention can preferably also be designed in such a way that the termination time is predicted during the first pressing-off process. This is in that regard It is advantageous that, as a rule, a more precise prognosis of the time of termination will be possible during the first pressing process than before the start of the first pressing process. At the same time, a prognosis of the termination time during the first push-off process allows a timely approaching process of the second dismantling unit in such a way that it has completed the approaching process at the termination time or shortly after this and has reached the drainage mountain.

Gemäß einer weiteren besonders bevorzugten Ausführungsform des erfindungsgemäßen Verfahrens wird der Beendigungszeitpunkt unter Berücksichtigung einer eingestellten Leistungsstufe der Ablaufanlage prognostiziert. Üblicherweise weisen rangiertechnische Ablaufanlagen beziehungsweise deren automatischen Steuerungssysteme unterschiedliche Leistungsstufen auf, die häufig als Prozentzahl der Maximalleistung angegeben werden (z.B. 100% oder 80%). Dabei hängt die jeweils aktive beziehungsweise eingestellte Leistungsstufe von jeweiligen betrieblichen Randbedingungen ab. Durch eine zusätzliche Berücksichtigung der eingestellten Leistungsstufe der Ablaufanlage bei der Prognose des Beendigungszeitpunkts wird vorteilhafterweise die Genauigkeit der Prognose erhöht.According to a further particularly preferred embodiment of the method according to the invention, the termination time is predicted taking into account a set power level of the drainage system. Shunting systems or their automatic control systems usually have different performance levels, which are often specified as a percentage of the maximum performance (e.g. 100% or 80%). The respective active or set power level depends on the respective operational boundary conditions. The accuracy of the prognosis is advantageously increased by additionally taking into account the set power level of the drainage system in the prognosis of the termination time.

Zusätzlich oder alternativ zu der zuvor beschriebenen bevorzugten Ausführungsform des erfindungsgemäßen Verfahrens kann dieses vorteilhafterweise auch derart weitergebildet sein, dass der Beendigungszeitpunkt unter Berücksichtigung einer im Rahmen des ersten Abdrückvorgangs aufgetretenen oder erwarteten Verzögerung prognostiziert wird. In der Praxis können im Rahmen von Abdrückvorgängen sowohl unerwartete als auch erwartete Verzögerungen auftreten. Dabei können erwartete beziehungsweise vorhersehbare Verzögerungen beispielsweise im Rahmen von Verfahren zur Behandlung von Gefahrgutwagen entstehen. So kann es hierbei in Abhängigkeit von der jeweiligen Betriebsweise erforderlich sein, dass ein vorausgehender Ablauf im Richtungsgleis angekommen ist, bevor der Gefahrgutwagen abgedrückt werden kann. Unerwartete Verzögerungen, die erst nach ihrem tatsächlichen Auftreten bei der Prognose des Beendigungszeitpunkts des ersten Abdrückvorgangs berücksichtigt werden können, können beispielsweise durch betriebsbedingte Unterbrechungen oder technische Störungen im Ablaufbetrieb verursacht sein. Unabhängig davon, ob es sich um eine im Rahmen des ersten Abdrückvorgangs bereits aufgetretene oder um eine im Rahmen des weiteren Abdrückvorgangs erwartete Verzögerung handelt, erlaubt die Berücksichtigung einer entsprechenden Verzögerung bei der Prognose des Beendigungszeitpunkts ebenfalls eine Steigerung der Genauigkeit der Prognose.In addition or as an alternative to the preferred embodiment of the method according to the invention described above, this can advantageously also be developed in such a way that the termination time is forecast taking into account a delay that has occurred or is expected in the course of the first pressing process. In practice, both unexpected and expected delays can occur in the course of the pressure relief operation. Expected or foreseeable delays can arise, for example in the context of procedures for handling dangerous goods wagons. Depending on the mode of operation, it may be necessary that a previous sequence has arrived in the direction track before the dangerous goods wagon can be pulled. Unexpected delays that can only be taken into account after their actual occurrence in the prognosis of the end time of the first pressure release process, can be caused, for example, by operational interruptions or technical malfunctions in the operational sequence. Regardless of whether it is a delay that has already occurred in the course of the first pressing process or a delay expected in the course of the further pressing process, taking into account a corresponding delay in the forecast of the termination time also allows an increase in the accuracy of the forecast.

Vorzugsweise kann das erfindungsgemäße Verfahren auch derart ausgestaltet sein, dass eine Simulation des ersten Abdrückvorgangs durchgeführt wird und der Beendigungszeitpunkt basierend auf der durchgeführten Simulation prognostiziert wird. Eine Simulation des ersten Abdrückvorgangs, bei der vorzugsweise Eigenschaften der Abläufe, wie beispielsweise Achsanzahl und Gewicht, sowie erwartete oder gemessene Laufeigenschaften der Abläufe berücksichtigt werden, ermöglicht vorteilhafterweise eine präzise Prognose der Dauer des ersten Abdrückvorgangs und damit auch des Beendigungszeitpunkts desselben.The method according to the invention can preferably also be designed in such a way that a simulation of the first pressing-off process is carried out and the termination time is predicted based on the simulation carried out. A simulation of the first pressing process, in which properties of the processes, such as the number of axles and weight, as well as expected or measured running characteristics of the processes, are advantageously taken into account, advantageously enables a precise prognosis of the duration of the first pressing process and thus also of the time it ends.

Vorzugsweise kann das erfindungsgemäße Verfahren hierbei weiterhin dahingehend ausgebildet sein, dass die Simulation des ersten Abdrückvorgangs zeitlich vor dem ersten Abdrückvorgang durchgeführt wird. Dies ist vorteilhaft, da eine entsprechende Simulation unter Verwendung detaillierter mathematischer Modelle auch für eine Planung, Optimierung und Steuerung des ersten Abdrückvorgangs als solchen genutzt werden kann. Die zu diesem Zwecke durchgeführte Simulation kann somit im Rahmen des erfindungsgemäßen Verfahrens vorteilhafterweise für die Prognose des Beendigungszeitpunkts des ersten Abdrückvorgangs verwendet werden.Preferably, the method according to the invention can furthermore be designed in such a way that the simulation of the first pressing-off process is carried out before the first pressing-off process. This is advantageous because a corresponding simulation using detailed mathematical models can also be used as such for planning, optimizing and controlling the first impression process. The simulation carried out for this purpose can thus advantageously be used in the context of the method according to the invention for the prognosis of the time at which the first pressure-release process will end.

Vorteilhafterweise kann das erfindungsgemäße Verfahren auch derart weitergebildet sein, dass während des ersten Abdrückvorgangs unter Berücksichtigung von aktuellen Positionsdaten zumindest eines Ablaufs der ersten Zerlegeeinheit und/oder unter Berücksichtigung von aktuellen Betriebsdaten der Ablaufanlage, insbesondere einer geänderten Leistungsstufe der Ablaufanlage und/oder einer im Ablaufbetrieb aufgetretenen Verzögerung, ein aktualisierter Geschwindigkeitsverlauf bestimmt wird und die Abdrücklokomotive gemäß dem aktualisierten Geschwindigkeitsverlauf gesteuert wird. Das erfindungsgemäße Verfahren beziehungsweise einzelne Schritte desselben können vorteilhafterweise während des ersten Abdrückvorgangs beziehungsweise während des Anrückvorgangs der zweiten Zerlegeeinheit wiederholt beziehungsweise erneut durchgeführt werden. Dies kann grundsätzlich beliebig oft geschehen und ermöglicht es, dass der Geschwindigkeitsverlauf der zweiten Zerlegeeinheit jeweils aktualisiert wird und damit auch bei Variationen im Abdrückbetrieb, z.B. in Folge von Verzögerungen des ersten Abdrückvorgangs oder Änderungen der Leistungsstufe der Ablaufanlage, jeweils der aktuellen Prognose des Beendigungszeitpunkts des ersten Abdrückvorgangs beziehungsweise der erwarteten Bergfreigabe für die zweite Zerlegeeinheit entspricht. Hierbei können vorteilhafterweise auch aktuelle Positionsdaten zumindest eines Ablaufs der ersten Zerlegeeinheit berücksichtigt werden, da sich aus diesen aktuellen Positionsdaten beispielsweise eine zeitliche Verschiebung im Vergleich zu einer ursprünglichen Simulation des ersten Abdrückvorgangs erkennen und durch eine entsprechende Anpassung beziehungsweise Aktualisierung des Geschwindigkeitsverlaufs der zweiten Zerlegeeinheit berücksichtigen lässt.The method according to the invention can advantageously also be developed in such a way that during the first pressing-off process taking into account current position data of at least one sequence of the first dismantling unit and / or taking into account current operating data of the sequence system, in particular a changed performance level of the sequence system and / or a delay that occurred in sequence operation, an updated speed profile is determined and the breaker locomotive is controlled according to the updated speed profile becomes. The method according to the invention or individual steps thereof can advantageously be repeated or carried out again during the first pressing-off process or during the approaching process of the second dismantling unit. In principle, this can be done any number of times and enables the speed profile of the second dismantling unit to be updated in each case and thus also in the event of variations in the pressure-releasing operation, e.g. as a result of delays in the first extraction process or changes in the performance level of the drainage system, the current prognosis of the termination time of the first Pressing-off process or the expected mountain clearance for the second dismantling unit corresponds. Here, current position data of at least one sequence of the first dismantling unit can advantageously also be taken into account, since this current position data can be used, for example, to identify a time shift compared to an original simulation of the first dismantling process and to take it into account by a corresponding adaptation or update of the speed profile of the second dismantling unit.

Der vorliegenden Erfindung liegt weiterhin die Aufgabe zugrunde, eine Steuereinrichtung für eine rangiertechnische Ablaufanlage anzugeben, durch welche die Leistungsfähigkeit der Ablaufanlage erhöht wird.The present invention is also based on the object of specifying a control device for a shunting drainage system, by means of which the performance of the drainage system is increased.

Diese Aufgabe wird erfindungsgemäß gelöst durch eine Steuereinrichtung für eine rangiertechnische Ablaufanlage, wobei die Steuereinrichtung ausgebildet ist, für eine erste Zerlegeeinheit, die im Rahmen eines ersten Abdrückvorgangs über einen Ablaufberg der Ablaufanlage abzudrücken ist, einen Beendigungszeitpunkt des ersten Abdrückvorgangs zu prognostizieren, für eine zweite Zerlegeeinheit, die von einer Abdrücklokomotive im Rahmen eines Anrückvorgangs in Richtung des Ablaufberges zu schieben und im Rahmen eines auf den ersten Abdrückvorgang folgenden zweiten Abdrückvorgangs über den Ablaufberg abzudrücken ist, unter Berücksichtigung zumindest des prognostizierten Beendigungszeitpunkts des ersten Abdrückvorgangs sowie einer aktuellen Position der zweiten Zerlegeeinheit einen Geschwindigkeitsverlauf zu bestimmen, gemäß dem ein unterbrechungsfreier Übergang des Anrückvorgangs in den zweiten Abdrückvorgang erfolgt, und die Abdrücklokomotive gemäß dem bestimmten Geschwindigkeitsverlauf zu steuern.According to the invention, this object is achieved by a control device for a shunting system, the control device being designed for a first dismantling unit, which is carried out as part of a first pressing-off process is to be pushed over a drainage mountain of the drainage system, to predict a termination time of the first pressure release process, for a second dismantling unit to be pushed by a pressure locomotive as part of a pushing process in the direction of the drainage mountain and to be pushed over the drainage mountain as part of a second pressure release process following the first pressure release process is to determine, taking into account at least the predicted termination time of the first push-off process and a current position of the second dismantling unit, a speed profile according to which an uninterrupted transition from the push-on process to the second push-off process takes place, and to control the push-pull locomotive according to the determined speed profile.

Die Vorteile der erfindungsgemäßen Steuereinrichtung entsprechen denjenigen des erfindungsgemäßen Verfahrens, so dass diesbezüglich auf die entsprechenden vorstehenden Ausführungen verwiesen wird.The advantages of the control device according to the invention correspond to those of the method according to the invention, so that reference is made in this regard to the corresponding statements above.

Es sei darauf hingewiesen, dass die erfindungsgemäße Steuereinrichtung in der Regel sowohl Hardwarebestandteile, etwa in Form zumindest eines entsprechenden Mikroprozessors, Controllers, Rechners oder Computers, als auch Softwarebestandteile, etwa in Form entsprechender Programmroutinen, aufweisen wird. Dabei ist die Steuereinrichtung im Betrieb der rangiertechnischen Ablaufanlage in der Regel in ein entsprechendes Steuerungssystem eingebunden, das neben der Steuereinrichtung üblicherweise weitere Komponenten aufweist, etwa in Form entsprechender Sensoren zur Erfassung von Messwerten sowie Aktoren zur Steuerung von Abdrücklokomotiven oder Gleisbremsen.It should be noted that the control device according to the invention will generally have both hardware components, for example in the form of at least one corresponding microprocessor, controller, calculator or computer, and software components, for example in the form of corresponding program routines. The control device is usually integrated into a corresponding control system during operation of the shunting system, which usually has other components in addition to the control device, for example in the form of corresponding sensors for recording measured values and actuators for controlling push-pull locomotives or track brakes.

Gemäß einer besonders bevorzugten Weiterbildung der erfindungsgemäßen Steuereinrichtung ist diese zum Durchführen einer der zuvor genannten bevorzugten Weiterbildungen des erfindungsgemäßen Verfahrens ausgebildet. Auch die Vorteile dieser bevorzugten Weiterbildung der erfindungsgemäßen Steuereinrichtung entsprechen denjenigen der entsprechenden bevorzugten Weiterbildungen des erfindungsgemäßen Verfahrens, so dass auch diesbezüglich auf die entsprechenden vorstehenden Erläuterungen verwiesen wird.According to a particularly preferred development of the control device according to the invention, it is designed to carry out one of the aforementioned preferred developments of the method according to the invention.

In den Figuren sind aus Gründen der Übersichtlichkeit gleiche Bestandteile mit denselben Bezugszeichen gekennzeichnet.For the sake of clarity, the same components are identified by the same reference symbols in the figures.

Für die im Folgenden beschriebenen Ausführungsbeispiele des erfindungsgemäßen Verfahrens sei angenommen, dass im Betrieb einer rangiertechnischen Ablaufanlage eine erste Zerlegeeinheit in Form eines zu zerlegenden Güterzuges im Rahmen eines ersten Abdrückvorgangs über einen Ablaufberg der Ablaufanlage abzudrücken ist beziehungsweise gerade von dem Ablaufberg der Ablaufanlage abgedrückt wird. Darüber hinaus befindet sich in der Zugbildungsanlage beziehungsweise rangiertechnischen Ablaufanlage eine zweite Zerlegeeinheit, die von einer (weiteren) Abdrücklokomotive im Rahmen eines Anrückvorgangs in Richtung des Ablaufberges zu schieben und im Rahmen eines auf den ersten Abdrückvorgang folgenden zweiten Abdrückvorgangs über den Ablaufberg abzudrücken ist beziehungsweise sein wird. Dabei setzt eine Befahrung des Ablaufberges durch die zweite Zerlegeeinheit, das heißt ein Starten des zweiten Abdrückvorgangs, voraus, dass das Abdrücken der ersten Zerlegeeinheit beendet (oder unterbrochen) ist. Sofern die Ablaufanlage lediglich ein Berggleis aufweist, hat der erste Abdrückvorgang beendet zu sein und darüber hinaus die Abdrücklokomotive der ersten Zerlegeeinheit den Ablaufberg beziehungsweise das Berggleis desselben geräumt zu haben, womit dieser für die zweite Zerlegeeinheit zur Verfügung steht. Falls die Ablaufanlage hingegen zwei (oder mehr) Berggleise aufweist, können die Abdrücklokomotive und gegebenenfalls auch weitere später noch abzudrückende Abläufe der ersten Zerlegeeinheit gegebenenfalls auch in ihrem Berggleis verbleiben.For the exemplary embodiments of the method according to the invention described below, it is assumed that in the operation of a shunting drainage system, a first dismantling unit in the form of a freight train to be dismantled is to be pushed over a drainage mountain of the drainage system as part of a first pressing process or is just being pressed off the drainage mountain of the drainage system. In addition, there is a second dismantling unit in the train formation system or the shunting system, which is to be pushed by a (further) push-off locomotive in the direction of the discharge mountain as part of an approach process and is or will be pushed over the discharge mountain as part of a second push-off process following the first push-off process . In this case, the second dismantling unit traversing the discharge mountain, that is to say starting the second dismantling process, requires that the dismantling unit has finished (or interrupted) the dismantling process. Provided If the drainage system has only one mountain track, the first pressure release process has to be completed and the pressure release locomotive of the first dismantling unit must also have cleared the drainage mountain or the mountain track of the same, so that it is available for the second dismantling unit. If, on the other hand, the drainage system has two (or more) mountain tracks, the push-pull locomotive and, if necessary, other processes of the first dismantling unit that are to be removed later can also remain in their mountain track.

Das Anrücken der zweiten Zerlegeeinheit in Richtung des Ablaufberges hängt somit hinsichtlich der Anrückgeschwindigkeit der Abdrücklokomotive, das heißt des Geschwindigkeitsverlaufs der zweiten Zerlegeeinheit, von dem ersten Abdrückvorgang beziehungsweise dessen Beendigung ab. Wie in dieser Situation eine vorteilhafte beziehungsweise bestenfalls optimale Steuerung des Geschwindigkeitsverlaufs der Abdrücklokomotive der zweiten Zerlegeeinheit erfolgen kann, soll nun anhand der Figuren im Detail beschrieben werden.The approach of the second dismantling unit in the direction of the discharge mountain thus depends on the first dismantling process or its termination with regard to the approach speed of the push-off locomotive, that is, the speed profile of the second dismantling unit. How in this situation an advantageous or, at best, optimal control of the speed profile of the breaker locomotive of the second dismantling unit can take place will now be described in detail with reference to the figures.

Figur 1 zeigt zur Erläuterung eines ersten Ausführungsbeispiels des erfindungsgemäßen Verfahrens in einer ersten schematischen Skizze ein erstes Zeit-Weg-Diagramm. Konkret ist hierbei die Zeit t als Funktion der von der Spitze der zweiten Zerlegeeinheit zurückgelegten Wegstrecke s aufgetragen. Dabei ist in Figur 1 eine erste Kurve erkennbar, die mit dem Bezugszeichen VAN01 gekennzeichnet ist. Veranlasst ist die entsprechende Kennzeichnung hierbei dadurch, dass die Steigung der Kurve ein Maß für die Geschwindigkeit der zweiten Zerlegeeinheit am jeweiligen Wegpunkt s beziehungsweise zum jeweiligen Zeitpunkt t ist. Aus diesem Grund werden die dargestellten Kurven in der Folge auch als "Geschwindigkeitsverlauf" oder "Geschwindigkeitskurve" bezeichnet, obwohl diese Bezeichnung mathematisch-physikalisch gesehen nicht völlig korrekt ist. Jedoch ist durch die jeweilige Zeit-Weg-Linie auch die Geschwindigkeit der zweiten Zerlegeeinheit (beziehungsweise der Abdrücklokomotive) zu jedem Zeitpunkt (aus der Steigung beziehungsweise Ableitung der Kurve) bestimmt beziehungsweise bestimmbar. Figure 1 shows in a first schematic sketch a first time-path diagram to explain a first exemplary embodiment of the method according to the invention. Specifically, the time t is plotted here as a function of the distance s covered by the tip of the second dismantling unit. In Figure 1 a first curve can be seen, which is identified by the reference symbol V AN01. The corresponding identification is caused by the fact that the slope of the curve is a measure of the speed of the second dismantling unit at the respective waypoint s or at the respective point in time t. For this reason, the curves shown are also referred to as “speed curve” or “speed curve” in the following, although this designation is not completely correct from a mathematical and physical point of view. However, the speed of the second dismantling unit (or the extraction locomotive) at each point in time (from the Slope or derivation of the curve) determined or determinable.

Gemäß der Kurve VAN01 beginnt der Anrückvorgang der zweiten Zerlegeeinheit ausgehend von einem Wegpunkt beziehungsweise Ort s0 bereits zu einem vergleichsweisen frühen Zeitpunkt t01. Dementsprechend erfolgt die Annäherung der zweiten Zerlegeeinheit an den Ablaufberg in diesem Fall mit einer vergleichsweise geringen Geschwindigkeit, die sich in der Darstellung der Figur 1 in einer entsprechenden vergleichsweise großen Steigung der Zeit-Weg-Kurve VAN01 niederschlägt. Im Vergleich hierzu ist ein zweiter, mit dem Bezugszeichen VAN02 gekennzeichneter Geschwindigkeitsverlauf (das heißt eine entsprechende zweite Zeit-Weg-Kurve) dargestellt, bei dem der Anrückvorgang erst zu einem späteren Zeitpunkt t02 beginnt. In beiden Fällen wird jedoch ein Punkt s1, der den Beginn des Ablaufberges kennzeichnet, zu einem Zeitpunkt t1 erreicht. Zu diesem Zwecke erfolgt der Anrückvorgang bei dem zweiten Geschwindigkeitsverlauf beziehungsweise der zweiten Geschwindigkeitskurve VAN02 mit einer im Vergleich zum ersten Fall größeren Geschwindigkeit, was sich in der Zeit-Weg-Darstellung der Figur 1 in einer entsprechend geringeren Steigung der Kurve zeigt.According to curve V AN01 , the approaching process of the second dismantling unit begins at a comparatively early point in time t 01, starting from a waypoint or location s 0 . Accordingly, the approach of the second dismantling unit to the discharge mountain takes place in this case with a comparatively low speed, which is shown in the illustration of the Figure 1 is reflected in a corresponding, comparatively large slope of the time-distance curve V AN01. In comparison to this, a second speed profile identified with the reference symbol V AN02 (that is to say a corresponding second time-distance curve) is shown, in which the approach process does not begin until a later point in time t 02 . In both cases, however, a point s 1 , which characterizes the beginning of the runoff mountain, is reached at a point in time t 1 . For this purpose, the approaching process takes place in the second speed curve or the second speed curve V AN02 at a higher speed than in the first case, which is shown in the time-distance illustration in FIG Figure 1 shows in a correspondingly lower slope of the curve.

Der in Figur 1 gezeigte Kurvenverlauf wird dadurch erreicht, dass im Rahmen des Betriebs der rangiertechnischen Ablaufanlage für die erste Zerlegeeinheit, die im Rahmen des ersten Abdrückvorgangs über den Ablaufberg der Ablaufanlage abzudrücken ist, ein Beendigungszeitpunkt des ersten Abdrückvorgangs prognostiziert wird. Dabei kann vorteilhafterweise zeitlich bereits vor dem ersten Abdrückvorgang eine Simulation desselben durchgeführt und der Beendigungszeitpunkt basierend auf dieser Simulation prognostiziert werden. In Abhängigkeit von der jeweiligen Realisierung kann es sich bei dem prognostizierten Beendigungszeitpunkt im Rahmen des beschriebenen Ausführungsbeispiels um den Zeitpunkt t1 oder um einen kurz vor diesem Zeitpunkt t1 liegenden Zeitpunkt handeln.The in Figure 1 The curve shown is achieved in that, during the operation of the shunting drainage system for the first dismantling unit, which is to be pressed over the drainage mountain of the drainage system as part of the first pressure release process, an end time of the first pressure release process is predicted. In this case, a simulation of the same can advantageously be carried out before the first pressing-off process and the termination time can be predicted on the basis of this simulation. Depending on the respective implementation, the predicted termination time in the context of the exemplary embodiment described can be time t 1 or a time shortly before this time t 1 .

Unter Berücksichtigung zumindest des prognostizierten Beendigungszeitpunktes des ersten Abdrückvorgangs sowie der jeweiligen aktuellen Position der zweiten Zerlegeeinheit wird sodann für die zweite Zerlegeeinheit ein Geschwindigkeitsverlauf bestimmt, gemäß dem ein unterbrechungsfreier Übergang des Anrückvorgangs in den zweiten Abdrückvorgang erfolgt. Der entsprechende unterbrechungsfreie Übergang des Anrückvorgangs in den zweiten Abdrückvorgang erfolgt im Rahmen des Ausführungsbeispiels der Figur 1 zum Zeitpunkt t1, das heißt dann, wenn die Spitze der zweiten Zerlegeeinheit den Ort s1 erreicht hat. Dabei kann es sich bei dem Ort beziehungsweise Punkt s1 um einen Anhaltepunkt des Ablaufbergs handeln, das heißt einen Punkt, für dessen Passieren durch die zweite Zerlegeeinheit ein Bergfreigabesignal beziehungsweise eine Bergfreigabe benötigt wird. Entsprechend der Darstellung der Figur 1 wird dieser Punkt sowohl im Falle der Geschwindigkeitskurve VAN01 als auch im Falle der Geschwindigkeitskurve VAN02 ohne Halt passiert, das heißt es erfolgt ein unterbrechungsfreier Übergang des Anrückvorgangs in den zweiten Abdrückvorgang. Entsprechend der Darstellung der Figur 1 gilt dies für beide Geschwindigkeitsverläufe VAN01 und VAN02 und somit unabhängig vom jeweiligen Startzeitpunkt t01 beziehungsweise t02 des Anrückvorgangs der zweiten Zerlegeeinheit in Richtung des Ablaufberges. Dies bedeutet, dass in beiden Fälle eine jeweils passende beziehungsweise bestenfalls optimale Geschwindigkeitskurve berechnet wird, mit der die anrückende zweite Zerlegeeinheit, das heißt der anrückende Zug, zum Zeitpunkt der Bergfreigabe beziehungsweise kurz danach am Ablaufberg ankommt, so dass ein Übergang beziehungsweise ein Wechsel von dem Anrückvorgang in den zweiten Abdrückvorgang ohne Unterbrechung möglich ist.Taking into account at least the predicted termination time of the first push-off process and the respective current position of the second dismantling unit, a speed profile is then determined for the second dismantling unit, according to which an uninterrupted transition from the approaching process to the second push-off process takes place. The corresponding uninterrupted transition from the approaching process to the second pressing process takes place within the scope of the exemplary embodiment in FIG Figure 1 at time t 1 , that is, when the tip of the second dismantling unit has reached location s 1 . The location or point s 1 can be a stopping point of the discharge mountain, that is to say a point for the passage of which through the second dismantling unit a mountain release signal or a mountain release is required. According to the representation of the Figure 1 this point is passed without stopping both in the case of the speed curve V AN01 and in the case of the speed curve V AN02, that is, there is an uninterrupted transition from the approaching process to the second push-off process. According to the representation of the Figure 1 this applies to both speed curves V AN01 and V AN02 and thus independent of the respective starting time t 01 or t 02 of the approaching process of the second dismantling unit in the direction of the discharge mountain. This means that in both cases a suitable or, at best, optimal speed curve is calculated with which the approaching second dismantling unit, i.e. the approaching train, arrives at the discharge mountain at the time the mountain is released or shortly thereafter, so that a transition or a change from the The approaching process in the second push-off process is possible without interruption.

Aus der zuvor beschriebenen Vorgehensweise ergeben sich bezogen auf den Gesamtbetrieb der rangiertechnischen Anlage eine Reduzierung von Abdrückpausen, eine Verringerung des Materialverschleißes und eine Reduzierung der Energiekosten durch Vermeidung eines unnötig schnellen Anrückens an den Ablaufberg mit anschließendem Bremsen, Anhalten und Wiederbeschleunigen nach Erhalt der Berg- beziehungsweise Abdrückfreigabe. Im Ergebnis resultiert somit vorteilhafterweise eine Erhöhung der Leistungsfähigkeit der Ablaufanlage sowie eine Schonung von Ressourcen. Insbesondere wird hierbei jeweils ein Geschwindigkeitsverlauf VAN01 beziehungsweise VAN02 bestimmt, der von einer als Alternative denkbaren Maxime einer schnellstmöglichen Ankunft am Ablaufberg abweicht. Hierdurch wird somit sowohl eine unnötige Abdrückpause durch ein zu spätes Anrücken der zweiten Zerlegeeinheit vermieden als auch ein Anhalten des Anrückvorgangs aufgrund einer fehlenden Bergfreigabe. Entsprechend der Darstellung in Figur 1 bestimmt beziehungsweise berechnet das Verfahren hierbei sowohl im Falle einem vergleichsweise frühen Startens des Anrückvorgangs als auch im Falle eines vergleichsweise späten Startens des Anrückvorgangs der zweiten Zerlegeeinheit an den Ablaufberg einen jeweiligen Geschwindigkeitsverlauf VAN01 beziehungsweise VAN02, der einen unterbrechungsfreien Übergang des Anrückvorgangs in den zweiten Abdrückvorgang erlaubt. Bezogen auf den zweiten Abdrückvorgang ergibt sich dabei entsprechend der Darstellung der Figur 1 nach Erreichen des Punktes s1 zum Zeitpunkt t1 in beiden Fällen derselbe Geschwindigkeitsverlauf vAB, gemäß dem die einzelnen Abläufe der zweiten Zerlegeeinheit von der Abdrücklokomotive über den Ablaufberg abgedrückt werden.The procedure described above results in a reduction in pressure breaks, a reduction in material wear and a reduction in energy costs in relation to the overall operation of the shunting system by avoiding an unnecessarily fast approach to the drainage mountain with subsequent braking, stopping and re-acceleration after receiving the clearance for the mountain or for the footprint. The result thus advantageously results in an increase in the performance of the drainage system as well as a conservation of resources. In particular, a speed profile V AN01 or V AN02 is determined in each case, which deviates from a conceivable alternative maxim of the fastest possible arrival at the discharge mountain. In this way, both an unnecessary pause for pressing due to the second dismantling unit being moved too late is avoided and the moving-in process is also prevented from being stopped due to a lack of mountain clearance. According to the representation in Figure 1 the method determines or calculates a respective speed profile V AN01 or V AN02 , which ensures an uninterrupted transition from the approach process to the second push-off process, both in the case of a comparatively early start of the approaching process and in the case of a comparatively late start of the approaching process of the second dismantling unit to the discharge hill allowed. In relation to the second push-off process, this results in accordance with the illustration in Figure 1 after reaching point s 1 at time t 1, in both cases the same speed curve v AB , according to which the individual processes of the second dismantling unit are pushed off by the push-off locomotive over the drainage mountain.

Die Prognose des Beendigungszeitpunkts erfolgt vorteilhafterweise während des ersten Abdrückvorgangs. Dabei kann der Beendigungszeitpunkt unter weiterer Berücksichtigung einer eingestellten Leistungsstufe der Ablaufanlage und/oder einer im Rahmen des ersten Abdrückvorgangs aufgetretenen oder erwarteten Verzögerung prognostiziert werden.The prognosis of the time of termination is advantageously carried out during the first push-off process. In this case, the termination time can be predicted taking into account a set power level of the drainage system and / or a delay that has occurred or is expected in the course of the first pressure release process.

Figur 2 zeigt zur Erläuterung eines zweiten Ausführungsbeispiels des erfindungsgemäßen Verfahrens in einer zweiten schematischen Skizze ein zweites Zeit-Weg-Diagramm. Die Darstellung der Figur 2 entspricht im Wesentlichen derjenigen der Figur 1, wobei im Unterschied zu Figur 1 zunächst lediglich ein Geschwindigkeitsverlauf vAN0 dargestellt ist, der sich basierend auf einem Startzeitpunkt des Anrückvorgangs der zweiten Zerlegeeinheit zu einem Zeitpunkt t0 ergibt. Im Unterschied zur Darstellung der Figur 1 erfolgt hierbei jedoch zu einem Zeitpunkt tn, zu dem die Spitze der zweiten Zerlegeeinheit einen Ort sn erreicht hat, eine Bestimmung eines aktualisierten Geschwindigkeitsverlaufs. Dies ist in Figur 2 dahingehend dargestellt, dass ausgehend von dem Punkt (sn, tn) der ursprünglich bestimmte Geschwindigkeitsverlauf vAN0 durch eine gestrichelte Linie angedeutet ist. Gemäß diesem weiteren Geschwindigkeitsverlauf vAN0 hätte die zweite Zerlegeeinheit somit den Ort s1, d.h. den Ablaufberg, zu einem Zeitpunkt t1 erreicht. Figure 2 shows in a second schematic sketch a second time-distance diagram to explain a second exemplary embodiment of the method according to the invention. The representation of the Figure 2 essentially corresponds to that of Figure 1 , being in contrast to Figure 1 initially only a speed profile v AN0 is shown, the is obtained based on a starting point in time of the approaching process of the second dismantling unit at a point in time t 0 . In contrast to the representation of the Figure 1 In this case, however, an updated speed profile is determined at a point in time t n at which the tip of the second dismantling unit has reached a location s n. This is shown in FIG. 2 to the effect that, starting from the point (s n , t n ), the originally determined speed profile v AN0 is indicated by a dashed line. According to this further speed profile v AN0 , the second dismantling unit would have reached the location s 1 , that is to say the discharge mountain, at a point in time t 1 .

Aufgrund der vorgenommenen Bestimmung des aktualisierten Geschwindigkeitsverlaufs, der in Figur 2 als strichpunktierte Linie dargestellt und mit dem Bezugszeichen vANn gekennzeichnet ist, ergibt sich nun jedoch ein abweichender Verlauf. Dies führt insbesondere dazu, dass die Spitze der zweiten Zerlegeeinheit den Ort s1 erst zu einem späteren Zeitpunkt t1' erreicht. Ursache hierfür ist, dass sich im Rahmen der Aktualisierung der Ermittlung des Geschwindigkeitsverlaufs gezeigt hat, dass sich der Abschluss des ersten Abdrückvorgangs verzögern wird und damit vor dem Zeitpunkt t1' ein unterbrechungsfreier Übergang des Anrückvorgangs in den zweiten Abdrückvorgang nicht möglich ist. Dabei kann die Bestimmung des aktualisierten Geschwindigkeitsverlaufs VANn insbesondere während des ersten Abdrückvorgangs unter Berücksichtigung des aktuellen Abdrückfortschritts der ersten Zerlegeeinheit, etwa anhand von aktuellen Positionsdaten zumindest eines Ablaufs der ersten Zerlegeeinheit, und/oder unter Berücksichtigung von aktuellen Betriebsdaten der Ablaufanlage, insbesondere einer geänderten Leistungsstufe der Ablaufanlage und/oder einer im Ablaufbetrieb aufgetretenen Verzögerung, erfolgen. Ab dem Zeitpunkt tn beziehungsweise dem Ort sn wird die zweite Zerlegeeinheit beziehungsweise die Abdrücklokomotive derselben damit gemäß dem neuen beziehungsweise aktualisierten Geschwindigkeitsverlauf vANn gesteuert. Die Aktualisierung des Geschwindigkeitsverlaufs kann hierbei unter Verwendung einer aktualisierten Prognose des Beendigungszeitpunkts des ersten Abdrückvorgangs erfolgen oder aber lediglich eine aufgetretene Verzögerung oder Verzögerungszeit berücksichtigen, ohne dass eine vollständig neue Prognose des Beendigungszeitpunkts vorgenommen wird.Based on the determination made of the updated speed profile, which is shown in Figure 2 is shown as a dash-dotted line and identified with the reference symbol v ANn, however, there is now a different course. This leads in particular to the fact that the tip of the second dismantling unit does not reach the location s 1 until a later point in time t 1 ' . The reason for this is that the updating of the determination of the speed profile has shown that the completion of the first push-off process will be delayed and thus an uninterrupted transition from the push-on process to the second push-off process is not possible before time t 1 '. In this case, the updated speed profile V ANn can be determined in particular during the first pressing process, taking into account the current pressing progress of the first dismantling unit, for example using current position data of at least one process of the first dismantling unit, and / or taking into account current operating data of the process system, in particular a changed performance level the sequence system and / or a delay that occurred in sequence operation. From the point in time t n or the location s n , the second dismantling unit or the extraction locomotive of the same is thus controlled according to the new or updated speed profile v ANn. The update of the speed profile can be done using a updated prognosis of the time of termination of the first triggering process or only take into account a delay or delay time that has occurred, without a completely new prognosis of the time of termination being made.

Die Berechnung beziehungsweise Bestimmung des Geschwindigkeitsverlaufs, gemäß dem die Abdrücklokomotive der zweiten Zerlegeeinheit gesteuert wird, kann während des Anrückvorgangs grundsätzlich beliebig oft durchgeführt werden. Hierbei ist sowohl eine regelmäßige Durchführung als auch insbesondere eine situationsbedingte erneute Durchführung der Bestimmung möglich. In beiden Fällen entspricht das Ergebnis auch bei auftretenden Variationen im Abdrückbetrieb jeweils der aktuellen Prognose der Bergfreigabe, so dass jeweils ein unterbrechungsfreier Übergang des Anrückvorgangs in den zweiten Abdrückvorgang erfolgt.The calculation or determination of the speed profile according to which the push-pull locomotive of the second dismantling unit is controlled can in principle be carried out as often as desired during the approach process. Both a regular implementation and, in particular, a situation-dependent repeated implementation of the determination is possible here. In both cases, the result corresponds to the current forecast of the mountain clearance, even if there are variations in the push-off operation, so that there is an uninterrupted transition from the approaching process to the second pushing-off process.

Entsprechend den vorstehenden Ausführungen im Zusammenhang mit den beschriebenen Ausführungsbeispielen des erfindungsgemäßen Verfahrens ermöglichen dieses sowie eine entsprechende Steuereinrichtung für eine rangiertechnische Ablaufanlage eine Erhöhung der Leistungsfähigkeit rangiertechnischer Ablaufanlagen. Dabei werden insbesondere durch das zeitgenaue Anrücken an den Ablaufberg zum Zeitpunkt der jeweiligen Bergfreigabe Pausen im Abdrückbetrieb verringert beziehungsweise vermieden. Darüber hinaus stellt das beschriebene Verfahren eine Grundlage beziehungsweise Voraussetzung für einen Anrückvorgang in einer vollautomatischen Ablaufanlage dar und ermöglicht somit eine weitere Erhöhung des Automatisierungsgrades rangiertechnischer Ablaufanlagen.Corresponding to the above statements in connection with the described exemplary embodiments of the method according to the invention, this and a corresponding control device for a marshalling process system enable an increase in the performance of the marshalling system. In this case, breaks in the push-off operation are reduced or avoided, in particular, by the precise time approaching the drainage mountain at the time of the respective mountain clearance. In addition, the described method represents a basis or prerequisite for an approaching process in a fully automatic drainage system and thus enables a further increase in the degree of automation of shunting technology drainage systems.
