Definitions
- the invention relates to a method according to the preamble of patent claim 1
- level crossings of this type will remain in operation for a long time, particularly on routes with low or medium traffic.
- Level railroad crossings in the station area are usually operated from a signal box, with barriers and light signals being controlled and secured via wire connections. Main signals that enable train travel via the level crossing can only be put into motion after the barrier lock signal has been reliably transmitted in terms of signal technology and the existing light signals have been switched on.
- Level crossings on the open track are often implemented as train crossings monitored by train drivers, whereby a switch contact triggers the barrier closing at a distance which is dependent on the maximum line speed, the worst train braking properties and the barrier closing time.
- a train driver signal at the braking distance before the signal gives the driver permission to pass when the level crossing is closed.
- the switch contacts and signals are connected to the logic unit of the level crossing by cable.
- the invention is therefore based on the object of carrying out the control of level crossings in a manner which eliminates the need for a cable connection along the route and which uses the possibilities of linear or punctiform train control.
- the closing request is triggered depending on a braking curve calculated from the braking properties of the vehicle and the route location of the level crossing in the path-speed diagram (driving profile), and therefore takes place at a route point depending on the current vehicle speed If the level crossing does not respond to the closing request, the vehicle can just be brought to a standstill by a service brake before the level crossing.
- the dimensioning specified in claim 2 ensures that the vehicle is not yet braked when the level crossing reacts correctly to the closing request.
- Claim 3 relates to further attempts to still close an initially unresponsive level crossing after braking has already been initiated, and the termination of braking if such attempts are successful.
- An embodiment reproduced in claim 4 relates to the processing of closing requests with regard to level crossings on multi-track routes, which can receive closing requests from several vehicles at the same time.
- Claim 7 and claim 8 relate to measures to continue driving in the event of a fault.
- a two-track railway route STR is shown schematically with a level crossing level BÜ, which is equipped with barriers SCH and light signals LS and can be closed and opened by radio from trains Z1, Z2 running on the route.
- the radio connection is either direct or via a signal box STW as a relay point to a level crossing logic BÜL, an intelligent control device near the level crossing, which is equipped with a transceiver for radio data transmission and controls and monitors the local actuators and sensors of the level crossing.
- the level crossing logic receives closing requests and reopening permits from the vehicles or the signal box STW via the transceiver and, after the level crossing closes, issues execution reports to the respective vehicles or the signal box.
- the route information necessary to calculate your driving curves - for which e.g. the location of a level crossing also belongs - the vehicles are given continuous transmission devices e.g. Line conductor LL or radio or via point-acting transmission devices PD communicated by the signal box.
- continuous transmission devices e.g. Line conductor LL or radio or via point-acting transmission devices PD communicated by the signal box.
- the path-speed diagram contains braking curves BR1, BR2 for all stopping points and slow-moving points, which each vehicle calculates based on the location of the stopping point and its own braking characteristics.
- the trains Z1, Z2 contained in FIG. 2 may have the same braking properties here, so that the same braking curves may apply to them at the level crossing BÜ and University BF stops.
- Train Z1 moves at high speed V1 towards the level crossing BÜ. From the route information, which the train has recorded via line conductors, radio or a point-like transmission device, the vehicle device of the train knows the period of time that the level crossing requires from the receipt of a closing request to the submission of a message about the closure being carried out. Depending on its speed, the train calculates the distance covered within this time and, at a time t1, at which it is a little further than this distance from the location at which it reaches the braking curve BR1, sends a closing request to the via radio Level crossing from.
- the level crossing reacts in accordance with regulations, after the closure has taken place, ie depending on the type of level crossing, the light signals show red and / or the barriers are closed and locked, it returns a completion report to the train at a time t2.
- the vehicle device then removes the stop assigned to your level crossing in its route list.
- the braking curve BR1 thus disappears and the train travels at a constant speed V1 to the next braking curve BR2, which e.g. is assigned to the station BF. If the level crossing does not react as required, no execution report is received at time t2. The train reaches braking curve BR1 and initiates service braking. The train brakes along the braking curve BR1 to a low passage speed Vd, with which it then passes the level crossing while driving with sight. However, the closing request can be repeated during the braking process. If the level crossing then still responds to the closing request, the braking process can be canceled and the train can be accelerated again after receipt of the execution report.
- the train Z2 traveling at a lower speed V2 sends its closing request to the level crossing BÜ at time t3. At this time, however, he had already approached the level crossing much closer. Due to the low speed, it can still be braked safely along the braking curve BR1 to the passage speed Vd if the message about the completion of the closure is not received from the level crossing at time t4. If such a message arrives in time, as in the case of train Z1, the stop associated with the level crossing BÜ is canceled and train Z2 continues at speed V2. After passing the level crossing, all trains give a reopening permit to the relevant level crossing. This occurs at a point in time t5 at a point at which the end of the train has left the level crossing.
- a section of track created at the level crossing which is implemented, for example, by a track circuit or by means of axle counting points, can also be used to check whether the level crossing is clear, i.e. the reopening permit is only implemented by the level crossing logic when the track section containing the level crossing is released.
- level crossings on multi-track lines it must also be checked before reopening whether there is a closing request from a train approaching on another track. In this case, the level crossing remains closed until a reopening permit has also been received by this train and / or a section of track formed in the other track has been occupied and has been cleared again.
Abstract
Description
Die Erfindung betrifft ein Verfahren gemäß dem Oberbegriff des Patentanspruches 1The invention relates to a method according to the preamble of patent claim 1
Obwohl grundsätzlich die Beseitigung aller schienengleichen Bahnübergänge angestrebt wird, werden, insbesondere an Strecken mit schwachem oder mittlerem Verkehrsaufkommen, noch lange Zeit derartige Bahnübergänge in Betrieb sein.Although the aim is to eliminate all level crossings that are the same as rails, level crossings of this type will remain in operation for a long time, particularly on routes with low or medium traffic.
Schienengleiche Bahnübergänge im Bahnhofsbereich werden heute in der Regel von einem Stellwerk aus bedient, wobei Schranken und Lichtsignale über Drahtverbindungen angesteuert und gesichert werden. Erst nach signaltechnisch sicher übertragener Rückmeldung des Schrankenverschlusses und der Anschaltung der vorhandenen Lichtsignale können Hauptsignale, die Zugfahrten über den Bahnübergang freigeben, auf Fahrt gestellt werden.Level railroad crossings in the station area are usually operated from a signal box, with barriers and light signals being controlled and secured via wire connections. Main signals that enable train travel via the level crossing can only be put into motion after the barrier lock signal has been reliably transmitted in terms of signal technology and the existing light signals have been switched on.
Bahnübergänge auf der freien Strecke werden häufig als Lokführer-überwachte Bahnübergänge ausgeführt, wobei ein Schaltkontakt in einem Abstand, der abhängig von der Streckenhöchstgeschwindigkeit, den schlechtesten Zugbremseigenschaften und der Schrankenschließzeit ist, das Schrankenschließen auslöst. Ein Lokführersignal im Bremswegabstand vor dem Signal gibt dem Triebfahrzeugführer dann die Erlaubnis zum Passieren, wenn der Bahnübergang verschlossen ist. Die Schaltkontakte und Signale sind mit der Logikeinheit des Bahnüberganges über Kabel verbunden.Level crossings on the open track are often implemented as train crossings monitored by train drivers, whereby a switch contact triggers the barrier closing at a distance which is dependent on the maximum line speed, the worst train braking properties and the barrier closing time. A train driver signal at the braking distance before the signal gives the driver permission to pass when the level crossing is closed. The switch contacts and signals are connected to the logic unit of the level crossing by cable.
Zusätzliche Sicherungsmaßnahmen für Bahnübergänge an Schnellfahrstrecken sind z.B. in einem Aufsatz von W.Köth und O. Wolf mit dem Titel "Der Beitrag der Signaltechnik zum Schnellverkehr" in "Eisenbahntechnische Rundschau", 1968, Heft 12, Seite 533, insbesondere in Kapitel IV, auf Seite 538 beschrieben.Additional security measures for level crossings on high-speed lines are e.g. described in an essay by W.Köth and O. Wolf with the title "The contribution of signal technology to high-speed traffic" in "Eisenbahntechnische Rundschau", 1968, Issue 12, page 533, in particular in Chapter IV, on page 538.
Sowohl die von Stellwerken aus gesteuerten Bahnübergänge als auch die Lokführer-überwachten Bahnübergänge auf der freien Strecke sind aufwendig in ihrer Unterhaltung. Die Kabelverbindungen entlang der Strecke und die erforderlichen, das Freifahren des Bahnüberganges meldenden Gleisschaltmittel sind außerdem störungsanfällig.Both the level crossings controlled by signal boxes and the level crossings monitored by the train driver on the open route are complex to maintain. The cable connections along the route and the required track switching means that signal the clearing of the level crossing are also prone to failure.
Der Erfindung liegt deshalb die Aufgabe zugrunde, die Steuerung von Bahnübergängen auf eine Weise vorzunehmen, die eine Kabelverbindung entlang der Strecke erübrigt und die die Möglichkeiten der linienförmigen oder punktförmigen Zugbeeinflussung nutzt.The invention is therefore based on the object of carrying out the control of level crossings in a manner which eliminates the need for a cable connection along the route and which uses the possibilities of linear or punctiform train control.
Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst.This object is achieved by the features of patent claim 1.
Dabei ist die Verwendung von Funk zur Fernsteuerung von Bahnübergangseinrichtungen vom Fahrzeug aus für sich bekannt (siehe z.B. DE 43 31 431 C1, Fig. 2 und Beschreibung Spalte 4, letzter Absatz bis Spalte 5, Zeile 21). Dort bestimmen jedoch ortsfeste Streckeneinrichtungen den Zeitpunkt der Ausgabe einer Sicherungsanforderung für den vorausliegenden Bahnübergang. Eine Berücksichtigung der individuellen Fahrzeuggeschwindigkeit bei der Bahnübergangssicherung ist damit dort nicht möglich, es muß vielmehr immer von der maximal möglichen Geschwindigkeit des schnellsten Fahrzeuges ausgegangen werden, was bei langsam sich nähernden Fahrzeugen unnötig lange Bahnübergangssperrzeiten bedingt. Bei dem Verfahren nach der Erfindung wird die Schließanforderung dagegen abhängig von einer aus den Bremseigenschaften des Fahrzeuges und dem Streckenort des Bahnüberganges berechneten Bremskurve im Weg- Geschwindigkeits-Diagramm (Fahrprofil) ausgelöst, erfolgt somit, abhängig von der aktuellen Fahrzeuggeschwindigkeit, an einem Streckenpunkt, von dem aus, sollte der Bahnübergang auf die Schließaufforderung nicht reagieren, das Fahrzeug gerade noch durch eine Betriebsbremsung vor dem Bahnübergang zum Stillstand gebracht werden kann.The use of radio for remote control of level crossing devices from the vehicle is known per se (see e.g. DE 43 31 431 C1, Fig. 2 and description column 4, last paragraph to column 5, line 21). There, however, fixed route facilities determine the point in time at which a security request is issued for the level crossing ahead. It is therefore not possible to take the individual vehicle speed into account when securing level crossings there; rather, the maximum possible speed of the fastest vehicle must always be assumed, which causes unnecessarily long level crossing blocking times for slowly approaching vehicles. In the method according to the invention, on the other hand, the closing request is triggered depending on a braking curve calculated from the braking properties of the vehicle and the route location of the level crossing in the path-speed diagram (driving profile), and therefore takes place at a route point depending on the current vehicle speed If the level crossing does not respond to the closing request, the vehicle can just be brought to a standstill by a service brake before the level crossing.
Ausgestaltungen des Verfahrens nach der Erfindung sind in den Unteransprüchen beschrieben.Embodiments of the method according to the invention are described in the subclaims.
So stellt die in Patentanspruch 2 angegebene Bemessung sicher, daß noch keine Bremsung des Fahrzeuges erfolgt, wenn der Bahnübergang auf die Schließanforderung vorschriftsmäßig reagiert.Thus, the dimensioning specified in claim 2 ensures that the vehicle is not yet braked when the level crossing reacts correctly to the closing request.
Anspruch 3 betrifft weitere Versuche, einen zunächst nicht reagierenden Bahnübergang nach bereits eingeleiteter Bremsung noch zu schließen, und den Abbruch der Bremsung, wenn derartige Versuche erfolgreich sind.Claim 3 relates to further attempts to still close an initially unresponsive level crossing after braking has already been initiated, and the termination of braking if such attempts are successful.
Eine in Anspruch 4 wiedergegebene Ausgestaltung betrifft die Verarbeitung von Schließanforderungen im Hinblick auf Bahnübergänge an mehrgleisigen Strecken, die gleichzeitig Schließanforderungen von mehreren Fahrzeugen bekommen können.An embodiment reproduced in claim 4 relates to the processing of closing requests with regard to level crossings on multi-track routes, which can receive closing requests from several vehicles at the same time.
Gegenstand der Ansprüche 5 und 6 ist die Wiederöffnung eines Bahnüberganges nach Durchfahrt eines Fahrzeuges.The subject of claims 5 and 6 is the reopening of a level crossing after passage of a vehicle.
Anspruch 7 und Anspruch 8 betreffen Maßnahmen zur Weiterführung des Fahrbetriebes im Störungsfall.Claim 7 and claim 8 relate to measures to continue driving in the event of a fault.
Anhand von zwei Figuren soll nun ein Ausführungsbeispiel für das Verfahren nach der Erfindung eingehend beschrieben werden.

- shows schematically a railway line with a level crossing and various facilities necessary for train control
- Fig. 2.
- shows driving profiles (distance-speed diagrams) for two trains in the area of a level crossing.
In Fig. 1 ist schematisch eine zweigleisige Eisenbahnstrecke STR wiedergegeben mit einem schienengleichen Bahnübergang BÜ, der mit Schranken SCH und Lichtsignalen LS ausgestattet ist und über Funk von auf der Strecke verkehrenden Zügen Z1, Z2 aus geschlossen und geöffnet werden kann. Die Funkverbindung besteht dabei entweder direkt oder über ein Stellwerk STW als Relaisstelle zu einer Bahnübergangslogik BÜL, einer intelligenten Steuereinrichtung in der Nähe des Bahnüberganges, die mit einer Sende- Empfangseinrichtung für Datenfunk ausgestattet ist und die lokalen Aktoren und Sensoren des Bahnüberganges ansteuert und überwacht. Über die Sende- Empfangseinrichtung empfängt die Bahnübergangslogik Schließanforderungen und Wiederöffnungs-Erlaubnisse von den Fahrzeugen oder dem Stellwerk STW und gibt nach Schließen des Bahnüberganges Vollzugsmeldungen an die jeweiligen Fahrzeuge bzw. das Stellwerk aus.In Fig. 1, a two-track railway route STR is shown schematically with a level crossing level BÜ, which is equipped with barriers SCH and light signals LS and can be closed and opened by radio from trains Z1, Z2 running on the route. The radio connection is either direct or via a signal box STW as a relay point to a level crossing logic BÜL, an intelligent control device near the level crossing, which is equipped with a transceiver for radio data transmission and controls and monitors the local actuators and sensors of the level crossing. The level crossing logic receives closing requests and reopening permits from the vehicles or the signal box STW via the transceiver and, after the level crossing closes, issues execution reports to the respective vehicles or the signal box.
Die zur Berechnung ihrer Fahrkurven notwendigen Streckeninformationen - zu denen z.B. auch der Ort eines Bahnüberganges gehört - bekommen die Fahrzeuge über kontinuierlich wirkende Übertragungseinrichtungen z.B. Linienleiter LL oder Funk oder über punktförmig wirkende Übertragungseinrichtungen PD vom Stellwerk mitgeteilt.The route information necessary to calculate your driving curves - for which e.g. the location of a level crossing also belongs - the vehicles are given continuous transmission devices e.g. Line conductor LL or radio or via point-acting transmission devices PD communicated by the signal box.
Fig. 2 zeigt im Weg (s)-Geschwindigkeits (v)-Diagramm zwei Fahrkurven mit den Anfangsgeschwindigkeiten V1 und V2, die zwei Zügen Z1 und Z2 zugeordnet sein mögen. Im Weg-Geschwindigkeits-Diagramm sind für alle Haltepunkte und Langsamfahrstellen Bremskurven BR1, BR2 enthalten, die jedes Fahrzeug nach dem Ort des Haltepunktes und den eigenen Bremseigenschaften berechnet. Die in der Figur 2 enthaltenen Züge Z1, Z2 mögen hier gleiche Bremseigenschaften haben, so daß für sie dieselben Bremskurven vor den Haltepunkten Bahnübergang BÜ und Bahnhof BF gelten mögen.2 shows in the path (s) -speed (v) diagram two driving curves with the initial speeds V1 and V2, which may be assigned to two trains Z1 and Z2. The path-speed diagram contains braking curves BR1, BR2 for all stopping points and slow-moving points, which each vehicle calculates based on the location of the stopping point and its own braking characteristics. The trains Z1, Z2 contained in FIG. 2 may have the same braking properties here, so that the same braking curves may apply to them at the level crossing BÜ and Bahnhof BF stops.
Zug Z1 fährt mit hoher Geschwindigkeit V1 auf den Bahnübergang BÜ zu. Aus der Streckeninformation, die der Zug über Linienleiter, über Funk oder über eine punktförmige Übertragungseinrichtung aufgenommen hat, kennt das Fahrzeuggerät des Zuges die Zeitspanne, die der Bahnübergang vom Empfang einer Schließanforderung an bis zur Abgabe einer Meldung über den erfolgten Verschluß benötigt. Je nach seiner gefahrenen Geschwindigkeit berechnet der Zug die innerhalb dieser Zeit zurückgelegte Strecke und gibt zu einer Zeit t1, zu der er sich noch etwas weiter als diese Strecke vor dem Ort befindet, an dem er die Bremskurve BR1 erreicht, über Datenfunk eine Schließanforderung an den Bahnübergang ab. Reagiert der Bahnübergang vorschriftsmäßig, so gibt er, nachdem der Verschluß erfolgt ist, d. h., je nach Art des Bahnüberganges, die Lichtsignale Rot zeigen und/oder die Schranken geschlossen und verriegelt sind, zu einer Zeit t2 eine Vollzugsmeldung an den Zug zurück. Das Fahrzeuggerät hebt daraufhin den dein Bahnübergang zugeordneten Haltepunkt in seiner Streckenliste auf.Train Z1 moves at high speed V1 towards the level crossing BÜ. From the route information, which the train has recorded via line conductors, radio or a point-like transmission device, the vehicle device of the train knows the period of time that the level crossing requires from the receipt of a closing request to the submission of a message about the closure being carried out. Depending on its speed, the train calculates the distance covered within this time and, at a time t1, at which it is a little further than this distance from the location at which it reaches the braking curve BR1, sends a closing request to the via radio Level crossing from. If the level crossing reacts in accordance with regulations, after the closure has taken place, ie depending on the type of level crossing, the light signals show red and / or the barriers are closed and locked, it returns a completion report to the train at a time t2. The vehicle device then removes the stop assigned to your level crossing in its route list.
Damit verschwindet die Bremskurve BR1 und der Zug fährt mit gleichbleibender Geschwindigkeit V1 bis zur nächsten Bremskurve BR2, die z.B. dem Bahnhof BF zugeordnet ist, weiter. Reagiert der Bahnübergang nicht wie vorgeschrieben, wird zum Zeitpunkt t2 keine Vollzugsmeldung empfangen. Der Zug erreicht die Bremskurve BR1 und leitet eine Betriebsbremsung ein. Dabei bremst der Zug entlang der Bremskurve BR1 bis auf eine niedrige Durchfahrtgeschwindigkeit Vd ab, mit der er dann den Bahnübergang unter Fahrt auf Sicht passiert. Während des Bremsvorganges kann jedoch die Schließanforderung wiederholt werden. Reagiert der Bahnübergang dann doch noch auf die Schließanforderung, so kann nach Empfang der Vollzugsmeldung der Bremsvorgang abgebrochen und der Zug wieder beschleunigt werden.The braking curve BR1 thus disappears and the train travels at a constant speed V1 to the next braking curve BR2, which e.g. is assigned to the station BF. If the level crossing does not react as required, no execution report is received at time t2. The train reaches braking curve BR1 and initiates service braking. The train brakes along the braking curve BR1 to a low passage speed Vd, with which it then passes the level crossing while driving with sight. However, the closing request can be repeated during the braking process. If the level crossing then still responds to the closing request, the braking process can be canceled and the train can be accelerated again after receipt of the execution report.
Der mit niedrigerer Geschwindigkeit V2 fahrende Zug Z2 sendet seine Schließanforderung zum Zeitpunkt t3, an den Bahnübergang BÜ ab. Er ist zu dieser Zeit aber bereits viel dichter an den Bahnübergang herangefahren. Aufgrund der niedrigen Geschwindigkeit kann er dennoch sicher entlang der Bremskurve BR1 auf die Durchfahrtgeschwindigkeit Vd abgebremst werden, wenn vom Bahnübergang nicht zum Zeitpunkt t4 die Meldung über den Vollzug des Verschlusses eingeht. Geht eine solche Meldung rechtzeitig ein wird, wie im Falle des Zuges Z1, der dem Bahnübergang BÜ zugeordnete Haltepunkt aufgehoben und der Zug Z2 fährt mit der Geschwindigkeit V2 weiter. Nach Passieren des Bahnüberganges geben alle Züge eine Wiederöffnungs-Erlaubnis an den betreffenden Bahnübergang ab. Dies geschieht zu einem Zeitpunkt t5 an einer Stelle, an der der Zugschluß den Bahnübergang verlassen hat. Ein am Ort des Bahnüberganges geschaffener Gleisabschnitt, der z.B. durch einen Gleisstromkreis oder mittels Achszählpunkten realisiert ist, kann zur Prüfung des Freiseins des Bahnüberganges zusätzlich herangezogen werden, das heißt, die Wiederöffnungs-Erlaubnis wird von der Bahnübergangslogik erst umgesetzt, wenn der den Bahnübergang enthaltende Gleisabschnitt freigemeldet ist.The train Z2 traveling at a lower speed V2 sends its closing request to the level crossing BÜ at time t3. At this time, however, he had already approached the level crossing much closer. Due to the low speed, it can still be braked safely along the braking curve BR1 to the passage speed Vd if the message about the completion of the closure is not received from the level crossing at time t4. If such a message arrives in time, as in the case of train Z1, the stop associated with the level crossing BÜ is canceled and train Z2 continues at speed V2. After passing the level crossing, all trains give a reopening permit to the relevant level crossing. This occurs at a point in time t5 at a point at which the end of the train has left the level crossing. A section of track created at the level crossing, which is implemented, for example, by a track circuit or by means of axle counting points, can also be used to check whether the level crossing is clear, i.e. the reopening permit is only implemented by the level crossing logic when the track section containing the level crossing is released.
Wird z. B. im Störungsfalle keine Wiederöffnungs-Erlaubnis empfangen, so kann nach Ablauf einer Wartezeit eine Wiederöffnung vorgenommen werden, wenn der am Ort des Bahnüberganges geschaffene Gleisabschnitt während der Zeit, in der der Bahnübergang geschlosen war, besetzt und wieder freigefahren wurde.Is z. B. in the event of a fault, no re-opening permit can be reopened after a waiting period if the section of track created at the level crossing was occupied and cleared again during the time in which the level crossing was closed.
Bei Bahnübergängen an mehrgleisigen Strecken ist vor Wiederöffnung außerdem zu prüfen, ob nicht von einem sich auf einem anderen Gleis nähernden Zug eine Schließanforderung vorliegt. In diesem Falle bleibt der Bahnübergang geschlossen bis auch von diesem Zug eine Wiederöffnungs-Erlaubnis empfangen wurde und/oder ein in dem anderen Gleis gebildeter Gleisabschnitt besetzt und wieder frei gefahren wurde.In the case of level crossings on multi-track lines, it must also be checked before reopening whether there is a closing request from a train approaching on another track. In this case, the level crossing remains closed until a reopening permit has also been received by this train and / or a section of track formed in the other track has been occupied and has been cleared again.
