Verfahren zum Betreiben einer Ablaufanlage des schienengebundenen Verkehrs sowie Steuer-Einrichtung für eine solche Ab¬ laufanlage Method for operating a drainage system of rail-bound traffic and control device for such Ab ¬ running system
In Ablaufanlagen der Rangiertechnik werden Schienenfahrzeuge unter Nutzung der auf die Schienenfahrzeuge wirkenden Schwerkraft aus einem Berggleis in unterschiedliche Richtungsgleise sortiert. Dabei handelt es sich bei den Schienenfahrzeugen um Wagen beziehungsweise Wagengruppen, die üblicherweise als Ab¬ läufe bezeichnet werden. In drainage systems of shunting technology rail vehicles are sorted using the force acting on the rail vehicles gravity from a mountain track in different direction tracks. These are among the rail cars to car or wagon groups which are commonly referred to as Ab ¬ runs.
Generell ist beim Betrieb einer Ablaufanlage eine möglichst genaue Prognose des Lauf erhaltens der Abläufe wünschenswert. Dies gilt einerseits im Hinblick darauf, Einholvorgänge der Abläufe während ihres Laufs in Richtung der Richtungsgleise zu vermeiden, da diese zu Unfällen oder Beschädigungen der Abläufe beziehungsweise der transportierten Güter führen könnten. Darüber hinaus erlaubt eine möglichst genaue Progno¬ se des LaufVerhaltens der einzelnen Abläufe auch eine Maxi- mierung der Kapazität der Ablaufanläge, d.h. eine Maximierung der Anzahl der mittels der Ablaufanlage in einem bestimmten Zeitraum sortierbaren Wagen. In general, the operation of a drainage system as accurate as possible prognosis of the running get the course is desirable. This applies, on the one hand, with regard to avoiding in-flight operations during their course in the direction of the directional tracks, since these could lead to accidents or damage to the processes or the transported goods. In addition, allows the most accurate Progno ¬ se of the running behavior of the individual processes also maximize the capacity of the Ablaufanläge, that a maximization of the number of sortable in a certain period by means of the draining assembly carriage.
Eine wichtige Einflussgröße bei der Steuerung einer Ablaufan¬ lage stellt der Rollwiderstand des jeweiligen Ablaufs dar, da dieser beispielsweise für die Steuerung von zur Beeinflussung der Geschwindigkeit der Abläufe vorgesehenen Gleisbremsen benötigt wird. Hierbei zeigt sich in der Praxis das Problem, dass anhand von Messgrößen, wie beispielsweise der Geschwin¬ digkeitsänderung sowie der Masse eines Ablaufs, ermittelte Rollwiderstände und daraus abgeleitete Prognosen für den Rollwiderstand des Ablaufs in einem nachfolgenden Gleisab- schnitt häufig nicht mit in dem nachfolgenden Gleisabschnitt letztlich tatsächlich basierend auf Messdaten ermittelten Rollwiderständen übereinstimmen. Dies hat zur Folge, dass die Rangierqualität, beispielsweise im Hinblick auf die Einhal¬ tung einer vorgegebenen Zielgeschwindigkeit beziehungsweise die Genauigkeit einer Laufzielbremsung, in vielen Fällen nicht in dem Maße gewährleistet werden kann, wie dies wün¬ schenswert wäre. An important factor in the control of a Ablaufan ¬ position represents the rolling resistance of the respective process, since this is needed, for example, for controlling intended for influencing the speed of the processes track brakes. This shows in practice the problem that on the basis of measured variables, such as Geschwin ¬ digkeitsänderung and the mass of a process, determined rolling resistances and derived forecasts for the rolling resistance of the process in a subsequent track departure often does not coincide with rolling resistance ultimately determined based on measured data in the subsequent track section. As a result, the shunting, for instance with respect to TO OBSERVE ¬ processing a predetermined target speed or the accuracy of a target braking system, in many cases can not be guaranteed to the same extent as would Wanting ¬ rule worth.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Betreiben einer Ablaufanlage des schienengebundenen Verkehrs anzugeben, das durch eine verbesserte Prognose des Rollwiderstands der Abläufe eine Erhöhung der Leistungs¬ fähigkeit der Ablaufanläge ermöglicht. The present invention has for its object to provide a method for operating a drain system of the rail-bound traffic, which allows an improved performance of the run ¬ ability of Ablaufanläge by an improved forecast of the rolling resistance of the processes.
Diese Aufgabe wird erfindungsgemäß gelöst durch ein Verfahren zum Betreiben einer Ablaufanlage des schienengebundenen Verkehrs, wobei für Abläufe in Form von ablaufenden Wagen beziehungsweise Wagengruppen in zumindest einem Gleisabschnitt der Ablaufanlage zumindest eine Rollwiderstands-Information ermittelt wird und unter Berücksichtigung der ermittelten Rollwiderstands-Information sowie zumindest einer für den jeweiligen Gleisabschnitt spezifischen Referenz-Rollwiderstands- Information der Rollwiderstand des jeweiligen Ablaufs in zu¬ mindest einem nachfolgenden Gleisabschnitt der Ablaufanlage prognostiziert wird. This object is achieved by a method for operating a drainage system of the rail-bound traffic, at least one rolling resistance information is determined for operations in the form of expiring cars or groups of cars in at least one track section of the drainage system and taking into account the determined rolling resistance information and at least one reference to rolling resistance ¬ least a subsequent track section, the flow system is predicted specific for the respective track section information of the rolling resistance of the respective flow in.
In einem ersten Schritt des erfindungsgemäßen Verfahrens wird somit in zumindest einem Gleisabschnitt der Ablaufanlage zu¬ mindest eine Rollwiderstands-Information ermittelt. Dabei hängt es von der konkreten Ausprägung der jeweiligen Ablaufanlage sowie gegebenenfalls darüber hinaus von Eigenschaften des jeweiligen Ablaufs, d.h. beispielsweise seiner Länge, ab, ob die Ermittlung der zumindest einen Rollwiderstands-Infor- mation lediglich in einem oder in mehreren Gleisabschnitten der Ablaufanläge erfolgt. Bei der Rollwiderstands-Information handelt es sich um eine auf den Rollwiderstand des jeweiligen Ablaufs bezogene Größe, welche einerseits durch den Rollwi¬ derstand selbst sowie andererseits auch durch eine andere Größe gegeben sein kann, welche mittelbar oder unmittelbar eine Aussage über den Rollwiderstand des jeweiligen Ablaufs erlaubt . In a first step of the method according to the invention in at least one track section of the flow system thus becomes minimum ¬ determines a rolling resistance information. In this case, it depends on the specific characteristics of the respective drainage system and optionally also on characteristics of the respective sequence, ie, for example, its length, whether the determination of the at least one rolling resistance information mation takes place only in one or more track sections of Ablaufanläge. In the rolling resistance of information is a related to the rolling resistance of the respective flow quantity which resistor can also be provided by a different size on the one hand by the Rollwi ¬ itself and on the other hand, which directly or indirectly a statement on the rolling resistance of the respective flow allowed.
Gemäß dem zweiten Schritt des erfindungsgemäßen Verfahrens wird unter Berücksichtigung der ermittelten Rollwiderstands- Information sowie zumindest einer für den jeweiligen Gleisabschnitt spezifischen Referenz-Rollwiderstands-Information der Rollwiderstand des jeweiligen Ablaufs in zumindest einem nachfolgenden Gleisabschnitt prognostiziert. Dies bedeutet, dass eine Prognose für den Rollwiderstand des jeweiligen Ab¬ laufs in dem zumindest einen nachfolgenden Gleisabschnitt ba¬ sierend auf der in dem zumindest einen, vorhergehenden Gleisabschnitt ermittelten Rollwiderstands-Information sowie der zumindest einen für den jeweiligen vorhergehenden Gleisabschnitt spezifischen Referenz-Rollwiderstands-Information erfolgt. In accordance with the second step of the method according to the invention, the rolling resistance of the respective sequence in at least one subsequent track section is predicted taking into account the determined rolling resistance information and at least one reference rolling resistance information specific to the respective track section. This means that a forecast for the rolling resistance of the respective Ab ¬ run in the at least one subsequent track section ba ¬ sierend on the in the at least one, the preceding track section determined rolling resistance information, and the at least one specific for the respective previous track section reference rolling resistance Information is provided.
Das erfindungsgemäße Verfahren ist vorteilhaft, da durch Ein¬ beziehung der Referenz-Rollwiderstands-Information eine verbesserte Vorhersage beziehungsweise Prognose des Rollwider¬ stands des jeweiligen Ablaufs in dem zumindest einen nachfol¬ genden Gleisabschnitt der Ablaufanlage ermöglicht wird. Vor¬ teilhafterweise können hierbei in die Referenz-Rollwiderstands-Information insbesondere anhand von vorhergehenden Abläufen gewonnene Erkenntnisse und Messwerte eingehen. Im Er¬ gebnis wird durch die erzielte Verbesserung der Prognose des Rollwiderstands der Abläufe die Leistungsfähigkeit, d.h. ins- besondere die Kapazität und/oder die Zuverlässigkeit, der Ab laufanläge erhöht. The inventive method is advantageous in that an improved prognosis or prediction of the rolling resistance ¬ stands of the respective flow in the at least one track section nachfol ¬ constricting the flow system is made possible by a ¬ relationship of the reference rolling resistance information. Before ¬ geous enough, can this be included in the reference rolling resistance information with particular reference gained from previous processes insights and readings. He in ¬ result is the achieved improvement of the prognosis of the rolling resistance of the processes the efficiency, ie INS particular the capacity and / or the reliability, the runnability increases.
Gemäß einer besonders bevorzugten Weiterbildung des erfin- dungsgemäßen Verfahrens wird der prognostizierte Rollwider¬ stand für die Steuerung zumindest einer Gleisbremse der Ab¬ laufanlage verwendet. Dies ist vorteilhaft, da somit die ver besserte Prognose des Rollwiderstands des jeweiligen Ablaufs in dem zumindest einen nachfolgenden Gleisabschnitt der Ab¬ laufanlage für eine Verbesserung der mittels der zumindest einen Gleisbremse erfolgenden Geschwindigkeitsbeeinflussung der Abläufe verwendet werden kann. Dies führt letztlich dazu dass vorgegebene Zielwerte für die Geschwindigkeit der Abläu fe an bestimmten Stellen der Ablaufanläge, d.h. beispielswei se im Bereich einer Förderanlage, oder im Falle einer Lauf¬ zielbremsung auch angestrebte Laufziele der Abläufe mit grö¬ ßerer Genauigkeit und Zuverlässigkeit eingehalten werden kön nen . According to a particularly preferred development of the inventive method, the rolling resistance ¬ was predicted is used for controlling at least one retarder of the Ab ¬ continuous system. This is advantageous because thereby in said at least one subsequent track section of Ab ¬ flow system can be used for an improvement of the at least one rail brake taking place by means of the speed influencing of the processes, the ver improved prediction of the rolling resistance of the respective flow. This ultimately leads to specified target values for the speed of the Abläu fe at certain points of Ablaufanläge, ie beispielswei se in the range of a conveyor system, or in the case of running ¬ target braking and desired objectives of the processes Kings are met with greater ¬ ßerer accuracy and reliability NEN ,
Gemäß einer weiteren besonders bevorzugten Aus führungs form ist das erfindungsgemäße Verfahren derart ausgestaltet, dass der Rollwiderstand unter Berücksichtigung der ermittelten Rollwiderstands-Information sowie zumindest einer für den je weiligen Gleisabschnitt und für den Laufweg des jeweiligen Ablaufs spezifischen Referenz-Rollwiderstands-Information prognostiziert wird. Vorteilhafterweise kann die Genauigkeit der Prognose weiterhin dadurch verbessert werden, dass die Referenz-Rollwiderstands-Information nicht nur für den jewei ligen Gleisabschnitt, sondern darüber hinaus auch für den je weiligen Laufweg des Ablaufs spezifisch ist. Hierbei ist zu berücksichtigen, dass die Rollwiderstände von Abläufen regel mäßig derart ermittelt werden, dass ausgehend von mehreren Geschwindigkeitsmessungen beziehungsweise Messungen von Über rollzeitpunkten von Achsen der Abläufe alle bekannten Effekt und Randbedingungen, wie beispielsweise Gleisneigungen, Gleiswiderstände, Windrichtung, Windstärke sowie Temperatur, berücksichtigt werden und der verbleibende Widerstand als Rollwiderstand des jeweiligen Ablaufs ermittelt beziehungs¬ weise festgelegt wird. Dabei kann in der Praxis beobachtet werden, dass der so ermittelte Rollwiderstand in Abhängigkeit von den jeweiligen Gegebenheiten nach wie vor eine Abhängigkeit von dem jeweiligen Laufweg des Ablaufs aufweisen kann. Diesem Effekt wird im Rahmen der zuvor genannten bevorzugten Weiterbildung des erfindungsgemäßen Verfahrens dadurch Rechnung getragen, dass für die Prognose des Rollwiderstands des jeweiligen Ablaufs in dem zumindest einen nachfolgenden According to a further particularly preferred embodiment, the method according to the invention is configured in such a way that the rolling resistance is predicted taking into account the determined rolling resistance information and at least one reference rolling resistance information specific to the respective track section and to the route of the respective sequence. Advantageously, the accuracy of the forecast can be further improved by the fact that the reference rolling resistance information is specific not only for the jewei time track section, but also for each respective path of the process. It should be noted that the rolling resistance of processes are regularly determined in such a way that starting from several speed measurements or measurements of roll over times of axes of the processes all known effect and boundary conditions, such as track gradients, track resistance, wind direction, wind speed and temperature, are taken into account and determines the remaining resistance as a rolling resistance of the respective process relationship ¬ is set. It can be observed in practice that the rolling resistance thus determined, depending on the particular circumstances, can still have a dependence on the respective path of the process. This effect is taken into account in the context of the aforementioned preferred development of the method according to the invention in that for the forecast of the rolling resistance of the respective sequence in the at least one subsequent
Gleisabschnitt eine für den jeweiligen Laufweg des Ablaufs spezifische Referenz-Rollwiderstands-Information verwendet wird . Track section is used for the respective route of the process specific reference rolling resistance information.
Vorzugsweise kann das erfindungsgemäße Verfahren auch derart ausgeprägt sein, dass der Rollwiderstand des jeweiligen Ab¬ laufs in dem zumindest einem nachfolgenden Gleisabschnitt un¬ ter Durchführung eines Vergleichs der ermittelten Rollwider- stands-Information sowie der zumindest einen Referenz-Roll- widerstands-Information prognostiziert wird. Dies ist vorteilhaft, da ein Vergleich der ermittelten Rollwiderstands- Information mit der zumindest einen Referenz-Rollwiderstands- Information eine Aussage zur Abweichung der ermittelten Roll- widerstands-Information von der zumindest einen Referenz- Rollwiderstands-Information ermöglicht . Preferably, the inventive method can also be so pronounced that the rolling resistance of the respective Ab ¬ run is in the at least one subsequent track section un ¬ ter performing a comparison of the determined rolling resistance subject information, and the at least one reference rolling resistance information predicts , This is advantageous since a comparison of the determined rolling resistance information with the at least one reference rolling resistance information makes it possible to make a statement about the deviation of the determined rolling resistance information from the at least one reference rolling resistance information.
Generell ist es im Rahmen der Prognose ausgehend von dem vor¬ genommenen Vergleich möglich, eine Korrektur der ermittelten Rollwiderstands-Information anhand der zumindest einen Referenz-RollwiderStands-Information vorzunehmen . Gemäß einer weiteren besonders bevorzugten Ausgestaltung des erfindungsgemäßen Verfahrens wird der Rollwiderstand im Rah¬ men der Prognose auf einen Ersatzwert festgelegt, sofern bei dem Vergleich eine betragsmäßig einen ersten Schwellenwert überschreitende Abweichung der ermittelten zumindest einenIn general, it is possible within the scope of the prognosis on the basis of the comparison that has been made to carry out a correction of the determined rolling resistance information on the basis of the at least one reference rolling resistance information. According to another particularly preferred embodiment of the method according to the invention, the rolling resistance in men Rah ¬ the forecast is set to a default value, except in the comparative magnitude, a first threshold value deviation exceeding the determined at least one
Rollwiderstands-Information von der zumindest einen Referenz- Rollwiderstands-Information festgestellt wird. Dies ist vorteilhaft, da somit für solche Fälle, in denen sich die ermit¬ telte Rollwiderstands-Information anhand des Vergleichs mit der Referenz-Rollwiderstands-Information als „Ausreißer" dahingehend darstellt, dass die Abweichung zwischen den beiden Größen einen ersten Schwellenwert betragsmäßig überschreitet, die ermittelte Rollwiderstands-Information verworfen und der Rollwiderstand im Rahmen der Prognose auf einen Ersatzwert festgelegt werden kann. Dabei handelt es sich bei dem jewei¬ ligen Ersatzwert vorzugsweise um den Wert, der sich aus der Referenz-Rollwiderstands-Information abzüglich beziehungsweise zuzüglich des ersten Schwellenwertes ergibt. Vorzugsweise kann das erfindungsgemäße Verfahren auch derart ablaufen, dass die zumindest eine für den jeweiligen Gleisab¬ schnitt spezifische Referenz-Rollwiderstands-Information unter Berücksichtigung der zumindest einen in dem jeweiligen Gleisabschnitt ermittelten Rollwiderstands-Information, des für den jeweiligen Ablauf in dem zumindest einen nachfolgenden Gleisabschnitt prognostizierten Rollwiderstands sowie ei¬ nes in dem zumindest einen nachfolgenden Gleisabschnitt bei Durchlaufen desselben ermittelten Rollwiderstandes angepasst wird. Dies ist dahingehend vorteilhaft, dass somit im Rahmen des Ablaufs des Verfahrens auf Basis eines Vergleichs zwi¬ schen dem für einen nachfolgenden Gleisabschnitt prognostizierten Rollwiderstand sowie dem in der Folge ermittelten be¬ ziehungsweise zurückgemeldeten tatsächlichen Rollwiderstand des Ablaufs in dem nachfolgenden Gleisabschnitt eine automa- tische Anpassung beziehungsweise Optimierung des Verfahrens erreicht wird. Dies führt einerseits beispielsweise im Falle der Inbetriebnahme einer Ablaufanlage dazu, dass die Refe- renz-Rollwiderstands-Information mit zunehmender Anzahl der erfolgten Abläufe immer genauer wird, wodurch somit insgesamt im Rahmen des Verfahrens auch die Prognose des Rollwider¬ stands der Abläufe verbessert wird. Rolling resistance information from the at least one reference rolling resistance information is determined. This is advantageous since thus for those cases in which the ermit ¬ Telte rolling resistance information based on the comparison with the reference rolling resistance information to the effect is represented as "outliers" means that the deviation between the two values exceeds a first threshold magnitude, the determined rolling resistance information discarded and the rolling resistance in the context of the prognosis can be set to a default value. This is at the jewei ¬ then substitute value, preferably the value which results from the reference rolling resistance information minus or plus the first threshold value is obtained. Preferably, the inventive method can also proceed so that the at least one for each Gleisab ¬ cut specific reference rolling resistance information taking into account the at least one determined in the respective track section rolling resistance information of the jew rapid sequence in the at least one subsequent track section predicted rolling resistance and ei ¬ nes in the at least one subsequent track section when passing through the same determined rolling resistance is adjusted. This is advantageous in that thus automatically as part of the sequence of the method based on a comparison Zvi ¬ rule the predicted for a subsequent track section rolling resistance and the determined subsequently be ¬ relationship reject reported actual rolling resistance of the flow in the subsequent track section Tische adjustment or optimization of the method is achieved. This leads on the one hand, for example, the placing in a drain system to the refer- ence-rolling resistance information with increasing number of performed processes is more and more accurate, thus the prognosis of the rolling resistance ¬ stands of processes is improved overall in the process.
Die Anpassung beziehungsweise Adaption der zumindest einen für den jeweiligen Gleisabschnitt spezifischen Referenz- Rollwiderstands-Information kann beispielsweise derart geschehen, dass durch eine Mittelwertbildung der ermittelten Rollwiderstands-Informationen eine Vielzahl von Abläufen berücksichtigt wird. Durch eine entsprechende höhere Gewichtung von solchen Abläufen, welche die Ablaufanlage zuletzt befah¬ ren haben, ist es hierbei vorteilhafterweise möglich, eine vergleichsweise schnelle Anpassung der jeweiligen Referenz- Rollwiderstands-Information an geänderte Bedingungen oder Gegebenheiten zu ermöglichen. Hierbei kann es sich einerseits um langfristige Effekte, wie beispielsweise verschleißbeding¬ te Änderungen, handeln. Durch eine ausgeprägte Übergewichtung zuletzt abgelaufener Abläufe, etwa mittels der so genannten Methode des exponentiellen Vergessens, ist es vorteilhafterweise darüber hinaus auch möglich, vergleichsweise kurzfris¬ tig auftretende Änderungen beziehungsweise Einflüsse zu be¬ rücksichtigen. Hierbei kann es sich beispielsweise um wetterbedingte Änderungen oder Umwelteinflüsse handeln, da bei¬ spielsweise Regen, Schnee oder Eis erhebliche Auswirkungen auf den Rollwiderstand der Abläufe haben. The adaptation or adaptation of the at least one reference rolling resistance information specific to the respective track section can, for example, take place in such a way that a multiplicity of sequences is taken into account by averaging the determined rolling resistance information. By an appropriate higher weighting of such processes, which have the hump yard last befah ¬ reindeer, it is hereby advantageously possible to allow a relatively rapid adjustment of the respective reference rolling resistance information to changing conditions or circumstances. On the one hand, these may be long-term effects, such as wear- related changes. By a pronounced overweight recently expired processes, for example by means of the so-called method of exponential forgetting, it is advantageously furthermore possible relatively short-¬ tig occurring changes or impacts to be taken into account ¬. This can be, for weather-related changes or environmental factors, for example, there are at ¬ play as rain, snow or ice a significant effect on the rolling resistance of the processes.
Gemäß einer weiteren besonders bevorzugten Aus führungs form ist das erfindungsgemäße Verfahren derart ausgeprägt, dass das Anpassen der zumindest einen Referenz-Rollwiderstands- Information unterbleibt, sofern die Abweichung zwischen der für den jeweiligen Gleisabschnitt ermittelten zumindest einen Rollwiderstands-Information und der zumindest einen Referenz- Rollwiderstands-Information betragsmäßig einen zweiten According to a further particularly preferred embodiment, the method according to the invention is so pronounced that the adaptation of the at least one reference rolling resistance information is omitted, provided that the deviation between the for the respective track section determined at least one rolling resistance information and the at least one reference rolling resistance information in terms of magnitude a second
Schwellenwert überschreitet. Diese Aus führungs form bietet den Vorteil, dass eine Anpassung beziehungsweise Adaption der zu¬ mindest einen Referenz-Rollwiderstands-Information nur bezogen auf solche Abläufe erfolgt, für welche die ermittelte zu¬ mindest eine Rollwiderstands-Information innerhalb eines vorgegebenen Streubereichs um die Referenz-Rollwiderstands- Information liegt. Hierdurch wird gewährleistet, dass eine Verfälschung der Referenz-Rollwiderstands-Information, etwa aufgrund eines einzelnen Messfehlers oder aufgrund eines Ab¬ laufs mit einem technischen Defekt, unterbleibt. Threshold exceeds. This disclosed embodiment provides the advantage that an adjustment or adaptation of the measured at ¬ least a reference rolling resistance information only with respect to such processes, for which the determined at ¬ least a rolling resistance information within a predetermined scattering area around the reference rolling resistance - Information is lying. This ensures that a distortion of the reference rolling resistance information, such as due to a single measurement error or due to a From ¬ run with a technical defect does not occur.
Wie bereits erläutert, kann es sich bei der Rollwiderstands- Information im Rahmen des erfindungsgemäßen Verfahrens vorteilhafterweise um eine beliebige Größe handeln, die mittel¬ bar oder unmittelbar eine Aussage über den Rollwiderstand des jeweiligen Ablaufs erlaubt. As already explained, it may be in the rolling resistance information as part of the process of the invention advantageously be any size which allows medium ¬ bar or just a statement about the rolling resistance of the respective process.
Vorzugsweise kann das erfindungsgemäße Verfahren auch derart weitergebildet sein, dass die zumindest eine Rollwiderstands- Information in Form einer auf das mittlere Achsgewicht des jeweiligen Ablaufs bezogenen Widerstandskraft ermittelt wird. Dies ist vorteilhaft, da sich in der Praxis zeigt, dass der Rollwiderstand eines Ablaufs insbesondere von der Masse be¬ ziehungsweise dem Gewicht des jeweiligen Ablaufs abhängt. So¬ fern als Rollwiderstands-Information eine auf das mittlere Achsgewicht des jeweiligen Ablaufs bezogene Widerstandskraft ermittelt wird, kann dieser Effekt vorteilhafterweise zumin¬ dest weitgehend berücksichtigt beziehungsweise korrigiert werden . Gemäß einer weiteren besonders bevorzugten Aus führungs form des erfindungsgemäßen Verfahrens wird der Rollwiderstand des jeweiligen Ablaufs in dem zumindest einen nachfolgenden Gleisabschnitt unter Berücksichtigung zumindest einer vom Ty des jeweiligen Ablaufs unabhängigen Referenz-Rollwiderstands Information prognostiziert. Zwar wäre es grundsätzlich denkbar, dass die Referenz-Rollwiderstands-Information spezifisc für den Typ beziehungsweise die Klasse des jeweiligen Ablauf ist. Eine Prognose unter Berücksichtigung beziehungsweise Verwendung einer vom Typ des jeweiligen Ablaufs unabhängigen Referenz-Rollwiderstands-Information bietet jedoch den Vorteil, dass sich der Verfahrensablauf als solcher vereinfacht Des Weiteren ist hierdurch sichergestellt, dass auch für Typen von Abläufen, die vergleichsweise selten auftreten, ausreichend genaue Referenz-Rollwiderstands-Informationen verfügbar sind, die vorteilhafterweise darüber hinaus auch ver¬ gleichsweise kurzfristig auftretende Änderungen der Betriebs bedingungen berücksichtigen. Preferably, the method according to the invention can also be developed such that the at least one rolling resistance information is determined in the form of a resistance force related to the average axle weight of the respective sequence. This is advantageous because in practice shows that the rolling resistance of a particular process be ¬ relationship, from the ground depending the weight of the respective process. So far a ¬ related to the axle weight average of the respective flow resistance is determined as the rolling resistance of information, this effect can be advantageously ¬ at least largely considered or corrected. According to a further particularly preferred embodiment of the method according to the invention, the rolling resistance of the respective sequence is predicted in the at least one subsequent track section, taking into account at least one reference rolling resistance information independent of the type of the respective course. Although it would be conceivable, in principle, that the reference rolling resistance information is specific to the type or class of the respective sequence. However, a prognosis taking into account or using a reference rolling resistance information which is independent of the type of the respective sequence offers the advantage that the method sequence as such is simplified. Furthermore, this ensures that also for types of sequences which occur comparatively rarely, sufficiently precise Reference rolling resistance information is available, which advantageously also consider ver ¬ comparatively short-term changes in operating conditions.
Vorzugsweise ist das erfindungsgemäße Verfahren weiterhin derart ausgeprägt, dass die zumindest eine Rollwiderstands- Information ausschließlich für Abläufe im freien, ungebremsten Lauf ermittelt wird. Dies ist vorteilhaft, da eine zuver lässige und damit ausreichend genaue Ermittlung einer Rollwi derstands-Information üblicherweise nur für solche Abläufe möglich ist, die während der Ermittlung der Rollwiderstands- Information, d.h. insbesondere während der Durchführung der hierfür erforderlichen Messungen, sich im freien, ungebremsten Lauf befinden. Preferably, the inventive method is further pronounced such that the at least one rolling resistance information is determined exclusively for operations in the free, unrestrained run. This is advantageous since a reliable and thus sufficiently accurate determination of rolling resistance information is usually only possible for those processes which occur during the determination of the rolling resistance information, i. especially while performing the measurements required for this, are in free, unrestrained running.

Diese Aufgabe wird erfindungsgemäß gelöst durch eine Steuer- Einrichtung für eine Ablaufanlage des schienengebundenen Ver- kehrs, wobei die Steuer-Einrichtung Mittel zum Durchführen des erfindungsgemäßen Verfahrens beziehungsweise zum Durch¬ führen einer der zuvor beschriebenen bevorzugten Weiterbildungen des erfindungsgemäßen Verfahrens aufweist. Hinsichtlich der Vorteile der erfindungsgemäßen Steuer- Einrichtung sei auf die entsprechenden vorstehenden Ausführungen im Zusammenhang mit dem erfindungsgemäßen Verfahren sowie seinen bevorzugten Weiterbildungen verwiesen. Im Folgenden wird die Erfindung anhand eines Ausführungsbei¬ spiels näher erläutert. Hierzu zeigt die This object is inventively achieved by a control device for a flow system of the rail-bound traffic, are wherein said control means comprises means for performing the method according to the invention or for guiding through ¬ one of the preferred developments of the method according to the invention described above. With regard to the advantages of the control device according to the invention, reference is made to the corresponding preceding statements in connection with the method according to the invention and its preferred developments. In the following the invention on the basis of an exemplary embodiment is explained in detail. This shows the
Figur in einer schematischen Darstellung ein Ausführungsbeispiel einer Ablaufanläge . Figure in a schematic representation of an embodiment of a Ablaufanläge.
In der Figur ist eine Ablaufanlage 10 erkennbar. Dabei stellt der obere Teil der Figur das Gleisbild der Ablaufanlage 10 und der untere Teil der Figur das Profil beziehungsweise ei¬ nen Längsschnitt der Ablaufanlage 10 dar. In the figure, a drainage system 10 can be seen. In this case, the upper part of the figure, the track diagram of the drainage system 10 and the lower part of the figure, the profile or egg ¬ nen longitudinal section of the drainage system 10 is.
Entsprechend der Darstellung der Figur weist die Ablaufanlage 10, die Bestandteil einer rangiertechnischen Anlage des schienengebundenen Verkehrs ist, eine Ablauframpe 20 auf, an die sich eine Zwischenneigung 30, eine Weichen aufweisende Verteilzone 40 sowie Richtungsgleise 50 anschließen. Darüber hinaus sind in der Figur Gleisbremsen in Form einer Talbremse 60 sowie in Form von Richtungsgleisbremsen 70 erkennbar. In dem Richtungsgleis 50 beziehungsweise in den Richtungsgleisen 50 ist darüber hinaus eine Förderanlage 80 vorgesehen. Alternativ hierzu wäre es beispielsweise auch denkbar, dass die Ablaufanlage im Hinblick auf eine Laufzielbremsung gesteuert wird und die in den jeweiligen Richtungsgleisen 50 zum Stillstand kommenden Abläufe von einer Rangierlok zwecks Ermögli- chung des Kuppeins der Wagen beziehungsweise Wagengruppen zu¬ sammengeschoben werden. According to the representation of the figure, the drainage system 10, which is part of a technical ranking system of the rail-bound traffic, a drain ramp 20, to which an intermediate slope 30, a points having Connect distribution zone 40 and directional tracks 50. In addition, in the figure track brakes in the form of a valley brake 60 and in the form of directional track brakes 70 can be seen. In addition, a conveyor 80 is provided in the directional track 50 or in the directional tracks 50. Alternatively, it would, for example, also conceivable that the drainage system is controlled with respect to a target braking and coming in the direction of tracks 50 to a halt operations of a shunting locomotive in order enable monitoring of Kuppeins the car or wagon groups are sammengeschoben to ¬.
Neben den genannten Komponenten der Ablaufanlage 10 sind in der Figur exemplarisch Abläufe 90 und 100 erkennbar, die von einer Abdrücklokomotive 110 über den Ablaufberg geschoben beziehungsweise abgedrückt worden sind und in der Folge ange¬ trieben durch die einwirkende Schwerkraft sich entlang der Ablaufanlage 10 bewegen. Im Sinne einer Maximierung der Kapazität des Ablaufanlage 10 sowie des Einhaltens einer vorgege- benen Zielgeschwindigkeit im Bereich der Förderanlage 80 be¬ ziehungsweise eines vorgesehenen Laufziels im Falle der Lauf¬ zielbremsung ist es hierbei erforderlich, basierend auf einer Prognose des LaufVerhaltens des jeweiligen Ablaufs 90, 100 eine Beeinflussung der Geschwindigkeit der Abläufe 90, 100 in der Talbremse 60 sowie in den Richtungsgleisbremsen 70 vorzunehmen . Besides the components mentioned, the process plant 10 processes 90 and 100 are exemplarily seen in the figure, which have been pushed by a Abdrücklokomotive 110 over the hump or pressed off, and subsequently be ¬ driven to move by the acting force of gravity along the flow conditioning 10th In the sense of maximizing the capacity of the drainage system 10 and of maintaining an above objectives set speed in the range of the conveyor 80 be ¬ relationship as an intended running target in the case of running ¬ Target braking, it is necessary in this case, based on a forecast of the running behavior of the respective flow 90, 100 an influence on the speed of the processes 90, 100 in the valley brake 60 and in the directional track brakes 70 make.
An dieser Stelle sei angemerkt, dass das in der Folge be¬ schriebene Verfahren selbstverständlich auch für solche Ab- laufanlagen einsetzbar ist, die zusätzlich eine dritte Bremsstaffel aufweisen oder bei denen die Geschwindigkeitsbeeinflussung in den Richtungsgleisen 50 mittels Kleinstbremsen, etwa in Form so genannter „Dowty-Retarder" , erfolgt. Im Rahmen des Betriebs der Ablaufanlage 10 kommt der Bestim¬ mung des Rollwiderstands der Abläufe 90, 100 eine große Be¬ deutung zu. So weisen Abläufe 90, 100 üblicherweise Rollwiderstände auf, die sich sowohl bezogen auf den jeweiligen Ablauf 90, 100 als auch in Abhängigkeit von den jeweiligen Bedingungen erheblich voneinander unterscheiden können. Eine Bestimmung des Rollwiderstands der Abläufe 90, 100 erfolgt üblicherweise basierend auf Geschwindigkeits- beziehungsweise Zeitmessungen, die im Rahmen der Steuerung der Ablaufanlage 10 vorgenommen werden. Ein entsprechendes Verfahren zum It should be noted that continuous systems the be ¬ specified in the following method, of course, for such waste is used, which additionally comprise a third brake relay or in which the speed-influencing so-called in the direction of tracks 50 by means of small brakes, such as in the form of "Dowty Retarder ". As part of the operation of the timing system 10 of Bestim ¬ tion of the rolling resistance of the processes 90, 100 a large Be ¬ importance occurs. Thus, processes 90, 100 usually have rolling resistance, which can differ considerably both with respect to the respective sequence 90, 100 and also depending on the respective conditions. A determination of the rolling resistance of the processes 90, 100 is usually carried out based on speed or time measurements that are made in the context of the control of the drainage system 10. A corresponding method for
Bestimmen des Rollwiderstands von Abläufen ist beispielsweise aus der veröffentlichten deutschen Patentanmeldung DE 42 14 541 AI bekannt. Darüber hinaus sind im Rahmen des erfindungs¬ gemäßen Verfahrens auch andere Verfahren zum Bestimmen des Rollwiderstands der Abläufe 90, 100 einsetzbar, wobei auch mehrere unterschiedliche Verfahren gleichzeitig angewandt werden können. Determining the rolling resistance of processes is known for example from the published German patent application DE 42 14 541 AI. In addition, other methods for determining the rolling resistance of the processes 90, 100 are usable in the context of the process according ¬ invention, wherein a plurality of different methods may be used simultaneously.
In Bezug auf ihre Steuerung kann die Ablaufanlage 10 in un¬ terschiedliche Gleisabschnitte unterteilt werden. Dies be¬ trifft beispielsweise den Bereich vor der Talbremse 60, den Bereich zwischen der Talbremse 60 und der Richtungsgleisbremse 70 sowie den Bereich in den Richtungsgleisen 50. Die Ermittlung des Rollwiderstands des jeweiligen Ablaufs 90, 100 ist insbesondere im Hinblick auf eine Prognose des Rollwider¬ stands für die Steuerung der Gleisbremsen der Ablaufanlage in Form der Talbremse 60 sowie der Richtungsgleisbremse 70 von Bedeutung. Hierbei ist es erforderlich, dass ausgehend von bereits vor dem Befahren der jeweiligen Gleisbremse vorliegenden Daten beziehungsweise Informationen sowie unter Berücksichtigung anlagenspezifischer Daten, wie beispielsweise von Gleisneigungen und Gleiswiderständen, eine möglichst genaue Prognose des Rollwiderstands in dem nachfolgenden, d.h. in Abiaufrichtung hinter der jeweiligen Gleisbremse gelegenen Gleisabschnitt, erfolgt. In terms of their control, the drain system can be divided into un ¬ terschiedliche track sections 10th This be ¬ case, for example the area in front of the Talbremse 60, the area between the Talbremse 60 and the direction of rail brake 70 and the area in the direction of tracks 50. The determination of the rolling resistance of the respective flow 90, 100 is particularly in view of the prediction of the rolling resistance ¬ stands for the control of the track brakes of the drainage system in the form of the valley brake 60 and the directional track brake 70 is important. In this case, it is necessary, starting from data or information already present before driving on the respective track brake, and taking into account plant-specific data, such as, for example, track gradients and track resistances, to obtain the most accurate forecast of the rolling resistance in the following, ie in Abiaufrichtung located behind the respective track brake track section takes place.
Gemäß dem erfindungsgemäßen Verfahren wird hierzu in zumin- dest einem Gleisabschnitt der Ablaufanlage 10 zumindest eine Rollwiderstands-Information ermittelt und der Rollwiderstand des jeweiligen Ablaufs 90, 100 in zumindest einem nachfolgenden Gleisabschnitt, d.h. beispielsweise in dem sich an die Talbremse 60 beziehungsweise die Richtungsgleisbremse 70 an- schließenden Gleisabschnitt, unter Berücksichtigung der ermittelten Rollwiderstands-Information sowie zumindest einer für den jeweiligen Gleisabschnitt, d.h. für den vor der jeweiligen Gleisbremse gelegenen Gleisabschnitt, spezifischen Referenz-Rollwiderstands-Information prognostiziert. In der Folge wird der auf diese Weise prognostizierte Rollwiderstand für die Steuerung der jeweiligen Gleisbremse in Form der Talbremse 60 beziehungsweise der Richtungsgleisbremsen 70 derart verwendet, dass der prognostizierte Rollwiderstand in die Berechnung der Sollauslaufgeschwindigkeit des Ablaufs 90 beziehungsweise 100 aus der jeweiligen Gleisbremse eingeht.According to the method according to the invention, at least one rolling resistance information is determined for this purpose in at least one track section of the drainage system 10, and the rolling resistance of the respective run 90, 100 in at least one subsequent track section, i. for example, in the track section adjoining the valley brake 60 or the directional track brake 70, taking into account the determined rolling resistance information and at least one for the respective track section, i. for the track section located in front of the respective track brake, specific reference rolling resistance information. As a result, the rolling resistance predicted in this way for the control of the respective track brake in the form of the valley brake 60 or the directional track brakes 70 is used such that the predicted rolling resistance is included in the calculation of the target discharge speed of the sequence 90 or 100 from the respective track brake.
Vorzugsweise erfolgt die Prognose des Rollwiderstands hierbei unter Berücksichtigung einer nicht nur für den jeweiligen Gleisabschnitt, sondern darüber hinaus auch für den jeweili¬ gen Laufweg des Ablaufs 90 beziehungsweise 100 spezifischen Referenz-RollwiderStands-Information . Preferably, the prediction of the rolling resistance in this case is carried out taking into account a specific not only for the respective track section, but also for the jeweili ¬ gen path of the flow 90 and 100 reference rolling resistance information.
Im Rahmen der Prognose des Rollwiderstands des jeweiligen Ab¬ laufs 90, 100 in dem zumindest einen nachfolgenden Gleisabschnitt wird vorteilhafterweise ein Vergleich der ermittelten Rollwiderstands-Information mit der zumindest einen Referenz- Rollwiderstands-Information vorgenommen. Hierdurch ist es für jeden bei der Prognose berücksichtigten Gleisabschnitt mög¬ lich, die Abweichung der jeweiligen ermittelten Rollwiderstands-Information von der jeweiligen zumindest einen Refe- renz-Rollwiderstands-Information zu bestimmen und diese Information, beispielsweise durch eine unterschiedliche Gewich¬ tung der jeweiligen Werte der Rollwiderstands-Information beziehungsweise der jeweiligen Differenzen, bei der Prognose des Rollwiderstands des jeweiligen Ablaufs 90, 100 zu berück¬ sichtigen . In the context of the prognosis of the rolling resistance of the respective Ab ¬ run 90, 100 in the at least one subsequent track section is advantageously a comparison of the determined rolling resistance information with the at least made a reference rolling resistance information. This makes it mög ¬ Lich for each considered when forecasting track section, the deviation of the respective rolling resistance determined information from the respective at least one refer- Renz rolling resistance information to be determined and this information, for example by a different weighting- ¬ processing of the respective values of the rolling resistance of information or of the respective differences in the prediction of the rolling resistance of the respective flow 90, 100 to be taken into ¬ into account.
Eine Anpassung beziehungsweise Adaption der Referenz-Roll- widerstands-Informationen, beispielsweise im Hinblick auf ge- änderte Umwelt- beziehungsweise Wetterbedingungen oder einen Verschleiß der Ablaufanlage 10, kann vorteilhafterweise der¬ art erfolgen, dass auf Basis eines Vergleichs zwischen dem für einen Ablauf 90, 100 prognostizierten sowie dem in der Folge ermittelten beziehungsweise zurückgemeldeten Rollwider- stand eine Anpassung der jeweiligen Referenz-Rollwiderstands- Information erfolgt. Dies bedeutet, dass die zumindest eine für den jeweiligen Gleisabschnitt spezifische Referenz-Roll- widerstands-Information unter Berücksichtigung der zumindest einen in dem jeweiligen Gleisabschnitt ermittelten Rollwider- stands-Information, des für den jeweiligen Ablauf 90, 100 in dem zumindest einen nachfolgenden Gleisabschnitt prognosti¬ zierten Rollwiderstands sowie eines in dem zumindest einen nachfolgenden Gleisabschnitt bei Durchlaufen desselben ermittelten Rollwiderstands angepasst beziehungsweise adaptiert wird. Vorteilhafterweise unterbleibt eine Adaption der Refe- renz-Rollwiderstands-Information hierbei für den Fall, dass die Abweichung zwischen der für den jeweiligen Gleisabschnitt ermittelten zumindest einen Rollwiderstands-Information und der zumindest einen Referenz-Rollwiderstands-Information be- tragsmäßig einen zweiten Schwellenwert überschreitet, d.h. außerhalb eines zugelassenen Streubereichs liegt. An adjustment or adaptation of the reference rolling resistance information, for example in terms of overall changed environmental or weather conditions or wearing of the flow conditioner 10 may advantageously be of the ¬ art take place in that, based on a comparison between a flow 90 100 predicted as well as subsequently determined or reported rolling resistance an adjustment of the respective reference rolling resistance information is carried out. This means that the at least one reference rolling resistance information specific to the respective track section is predicted taking into account the at least one rolling resistance information determined in the respective track section, for the respective run 90, 100 in the at least one subsequent track section ¬ ed rolling resistance and one in the at least one subsequent track section when passing through the same determined rolling resistance is adapted or adapted. Advantageously, an adaptation of the reference rolling resistance information in this case is omitted for the case in which the deviation between the at least one rolling resistance information determined for the respective track section and the at least one reference rolling resistance information exceeds a second threshold value, ie outside a permitted range.
Die Rollwiderstands-Information kann vorteilhafterweise in Form einer auf das mittlere Achsgewicht des jeweiligen Ab- laufs 90, 100 bezogenen Widerstandskraft ermittelt werden. In diesem Fall kann die Referenz-Rollwiderstands-Information vorteilhafterweise durch eine Referenzwiderstandskraftgerade gegeben sein, welche die auf das mittlere Achsgewicht des je- weiligen Ablaufs bezogene Widerstandskraft als Funktion des mittleren Achsgewichts darstellt. Dabei unterscheiden sich die Referenzwiderstandskraftgeraden vorteilhafterweise im Hinblick auf den jeweiligen Laufweg des jeweiligen Ablaufs 90, 100 dahingehend, dass beispielsweise für jeden Gleisab- schnitt nach der Talbremse 60 Referenzwiderstandskraftgeraden unterschiedlicher Steigung vorgesehen, d.h. in einer Speicher-Einrichtung der Ablaufanlage 10 abgespeichert, sind. The rolling resistance information may advantageously be in the form of an average axle weight of the respective axle weight. Run 90, 100 related resistance can be determined. In this case, the reference rolling resistance information may advantageously be given by a reference resistance force straight line which represents the resistance force related to the average axle weight of the respective sequence as a function of the average axle weight. In this case, the reference resistance straight lines advantageously differ with regard to the respective travel path of the respective sequence 90, 100 in that, for example, reference resistance force lines of different pitch are provided for each track section after the valley brake 60, ie stored in a storage device of the drainage system 10.
Die Ermittlung der Rollwiderstands-Information erfolgt vor- zugsweise ausschließlich für Abläufe 90, 100 im freien, ungebremsten Lauf. Für solche Abläufe 90, 100, für die der freie, ungebremste Lauf beispielsweise aufgrund der Länge des be¬ treffenden Ablaufs nicht erreicht wird, kann der Rollwiderstand vorteilhafterweise durch einen weiteren Ersatzwert er- setzt beziehungsweise bestimmt werden, der beispielsweise aus der jeweiligen Referenz-Rollwiderstands-Information ermittelt werden kann. The determination of the rolling resistance information is preferably carried out exclusively for processes 90, 100 in the free, unbraked run. For such processes 90, 100, for which the free, unbraked run is not achieved, for example due to the length of the relevant sequence, the rolling resistance can advantageously be replaced or determined by a further substitute value, for example from the respective reference rolling resistance Information can be determined.
Das zuvor beschriebene Verfahren bietet den Vorteil, dass es mittels der Referenz-Rollwiderstands-Information möglich wird, dass „Erfahrungen", die im Rahmen der Behandlung früherer Abläufe gemacht worden sind, in Form der Referenz-Roll¬ widerstands-Information für die Steuerung späterer beziehungsweise nachfolgender Abläufe Verwendung finden. Darüber hinaus ermöglicht es die beschriebene Anpassung beziehungs¬ weise Adaption der Referenz-Rollwiderstands-Information vorteilhafterweise, dass Änderungen in den Betriebsbedingungen der Ablaufanlage 10 automatisch und zeitnah bei der Steuerung der Anlage berücksichtigt werden. Im Ergebnis resultiert hierdurch somit aufgrund der sich ergebenden Verbesserung der Prognose des Rollwiderstands eine Erhöhung der Leistungsfä¬ higkeit, d.h. insbesondere der Kapazität und/oder der Zuver¬ lässigkeit, der Ablaufanlage 10. The method described above has the advantage that it is possible by means of the reference rolling resistance information that "experiences" that have been made in the context of the treatment of previous processes, in the form of reference Roll ¬ resistance information for the controller later find or subsequent processes use. Additionally, it enables the adaptation relationship ¬ as adaptation of the reference rolling resistance information described advantageously that changes in the operating conditions of the end system 10 automatically and promptly taken into account in the control of the system. as a result, results thereby thus due to the resulting improvement of the prognosis of the rolling resistance increase the Leistungsfä ¬ ability, that is, in particular, the capacity and / or the Zuver ¬ permeability, the flow conditioning 10th
