Description

Die vorliegende Erfindung bezieht sich auf ein Lichtsignal zur Anzeige von Signalbegriffen für einen Verkehrsweg.The present invention relates to a light signal for displaying signal aspects for a traffic route.

Lichtsignale werden zur Steuerung von Verkehrsflüssen in vielfältigster Weise im Strassen-, Eisenbahn-, Flug- und Schiffsverkehr eingesetzt. Grundsätzlich ist bei allen Lichtsignalen wichtig, dass sie von dem jeweiligen Führer des Fahrzeugs (wie z.B. Auto, Zug, Flugzeug, Schiff) gut und verwechslungsfrei erkannt werden können. Dabei spielen sowohl die Topologie des Verkehrsweges als auch die möglichen Fahrgeschwindigkeiten eine entscheidende Rolle. Aus diesem Grunde weisen beispielsweise Eisenbahnlichtsignale vordefinierte Abstrahlkeulen zur Darstellung der Signalbegriffe auf, die jedoch nicht immer eine gleichgute Sichtbarkeit des Signalbegriffs herbeiführen können. So ist beispielsweise der Signalbegriff für einen dicht vor dem Lichtsignal stehenden Zug nicht optimal wahrnehmbar. Besonders in Kurven kann es auch dazu kommen, dass bei einem Doppelgleis beide Gleise die Abstrahlkeule eines Lichtsignals schneiden können, obwohl das Lichtsignal nur für eines der beiden Gleise gilt. Verwechslungen können die Folge sein, so dass im schlimmsten Fall sogar ein HALT zeigendes Lichtsignal überfahren wird.Light signals are used to control traffic flows in a wide variety of ways in road, rail, air and ship traffic. With all light signals, it is fundamentally important that the driver of the vehicle (such as a car, train, plane, ship) can recognize them easily and without confusion. Both the topology of the traffic route and the possible driving speeds play a decisive role. For this reason, for example, railway light signals have predefined radiation lobes for displaying the signal aspects, which, however, cannot always bring about an equally good visibility of the signal aspect. For example, the signal aspect for a train standing close to the light signal is not optimally perceptible. Especially in curves, it can happen that both tracks on a double track can intersect the beam of a light signal, although the light signal only applies to one of the two tracks. Mix-ups can result, so that in the worst case even a light signal showing STOP is run over.

Aus diesem Grund ist es erforderlich, die Abstrahlkeule eines Lichtsignalpunktes optimal auf die vorhandene Topologie des Verkehrsweges auszurichten. Trotz der fortschreitenden Verbreitung von Strecken mit ETCS Level 2, das den Zugverkehr ohne Aussensignale mittels Führerstandsignalisierung steuert, werden Aussensignale für die nächsten Jahrzehnte in Europa für den Zugverkehr weiterhin eine bedeutende Rolle spielen.For this reason, it is necessary to optimally align the radiation lobe of a light signal point to the existing topology of the traffic route. Despite the increasing spread of lines with ETCS Level 2, which controls train traffic without outside signals by means of driver's cab signaling, outside signals will continue to play an important role for train traffic in Europe for the next few decades.

Deswegen wird auch zur Erzielung der gewünschten Abstrahlkeule ein grosser Aufwand getrieben. Für die Leuchtpunkte eines Lichtsignals stehen eine Anzahl unterschiedlicher Linsen zur Verfügung, mit denen sich unterschiedlich breite Abstrahlkeulen realisieren lassen und die nach Rechts- und Linksaufstellung der Lichtsignale unterteilt sind. Diese Vielfalt an verfügbaren Linsen erschwert die Reparatur defekter Leuchtpunkte, weil der Ersatz immer auch wieder dieselbe Abstrahlkeule aufweisen muss. Zudem sind auch die Ersatzteilhaltung und die Weiterentwicklung der Lichtsignale schwierig. Ebenso werden beim Austausch der Linse hohe Umweltanforderungen an die Dichtigkeit des Lichtpunktes gestellt, sodass ein leichter Austausch einer Linse im Feld nicht möglich ist.Therefore, a great deal of effort is made to achieve the desired radiation lobe. For the A number of different lenses are available for luminous points of a light signal, with which radiation lobes of different widths can be realized and which are divided according to the right and left position of the light signals. This variety of available lenses makes it difficult to repair defective luminous points because the replacement must always have the same beam. In addition, the spare parts inventory and the further development of the light signals are difficult. Likewise, when the lens is exchanged, high environmental requirements are placed on the tightness of the light point, so that an easy exchange of a lens in the field is not possible.

In dem Dokument EP2488401 B1 wird ein Lichtsignal mit mehreren Leuchtpunkten gezeigt, bei dem die Abstrahlrichtung variiert werden kann.In the document EP2488401 B1 a light signal with several light points is shown, in which the direction of emission can be varied.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Lichtsignal und ein Verfahren zur Anzeige von Signalbegriffen für einen Verkehrsweg anzugeben, bei denen die Einstellung unterschiedlicher Abstrahlkeulen in einfacher Weise ohne eine grosse Bevorratung von Linsen und weiteren Bauteilen erzielt werden kann. Zudem soll ein Leuchtpunkt auch im Fall eines Defekts einfach ersetzbar sein.The present invention is therefore based on the object of specifying a light signal and a method for displaying signal terms for a traffic route, in which the setting of different radiation lobes can be achieved in a simple manner without a large stock of lenses and other components. In addition, a light point should also be easily replaceable in the event of a defect.

Bezüglich des Lichtsignals wird diese Aufgabe erfindungsgemäss durch ein Lichtsignal gemäß Anspruch 1 gelöst.With regard to the light signal, this object is achieved according to the invention by a light signal according to claim 1.

Bezüglich des Verfahrens wird diese Aufgabe erfindungsgemäss durch ein Verfahren gemäß Anspruch 4 gelöst.With regard to the method, this object is achieved according to the invention by a method according to claim 4.

Auf diese Weise werden ein Lichtsignal und Verfahren zum Anzeigen von Signalbegriffen geschaffen, die durch eine entsprechende, vorzugsweise auch programmierbare Ansteuerung der Leuchtelemente die Signalbegriffe mit der gewünschten Abstrahlkeule abstrahlen. Es bedarf daher keiner oder nur noch einer kleinen Anzahl von Linsen, um die Signalbegriffe mit entsprechend adaptierter Abstrahlkeule darstellen zu können. Ersatzteile können so relativ freizügig eingesetzt werden, wobei ihnen dann lediglich durch die entsprechende Programmierung die korrekte Abstrahlkeule bekannt gemacht werden muss.In this way, a light signal and a method for displaying signal terms are created, which emit the signal terms with the desired radiation lobe by means of a corresponding, preferably also programmable, control of the light elements. No or only a small number of lenses are therefore required in order to be able to represent the signal aspects with a correspondingly adapted radiation lobe. Spare parts can thus be used relatively freely, in which case the correct radiation lobe only needs to be made known to them through the appropriate programming.

Erfindungsgemäß ist eine Sensorik zur Erfassung der Annäherung eines Fahrzeugs entlang des Verkehrsweges auf das Lichtsignal vorgesehen, wobei die Steuerungseinheit in Antwort auf eine detektierte Annäherung des Fahrzeugs die Leuchtelemente zur Erzielung einer dynamischen Abfolge von vorbestimmten Abstrahlkeulen ansteuert. Somit kann die programmierte Abfolge von Abstrahlkeule die Signalbegriffe stets optimal auf die projektierte Vorbeifahrtgeschwindigkeit abgestimmt abstrahlen. Je nach Krümmung des Verkehrsweges kann eine derartige Abfolge beliebig viele verschiedene Abstrahlkeulen umfassen.According to the invention, a sensor system is provided for detecting the approach of a vehicle along the traffic route to the light signal, the control unit activating the light elements in response to a detected approach of the vehicle to achieve a dynamic sequence of predetermined radiation lobes. In this way, the programmed sequence of radiation lobes can always emit the signal aspects in an optimally matched manner to the projected pass-by speed. Depending on the curvature of the traffic route, such a sequence can include any number of different radiation lobes.

Alternativ kann es auch vorgesehen sein, dass ein Näherungssensor zur Erfassung der Annäherung eines Fahrzeugs entlang des Verkehrsweges auf das Lichtsignal zu vorgesehen ist, wobei die Steuerungseinheit in Antwort auf einen detektierten Annäherungsverlauf des Fahrzeugs die Leuchtelemente zur Erzielung einer dynamischen Abfolge von vorbestimmten Abstrahlkeulen in Abhängigkeit vom detektierten Annäherungsverlauf ansteuert. Somit kann jeweils in Antwort auf den detektierten Abstand des Fahrzeugs vom Lichtsignal die für diesen Abstand bzw. Abstandsbereich projektierte Abstrahlkeule zur Anwendung kommen.Alternatively, it can also be provided that a proximity sensor is provided for detecting the approach of a vehicle along the traffic route to the light signal, wherein the control unit, in response to a detected approach of the vehicle, the light elements to achieve a dynamic sequence of predetermined radiation lobes depending on the controls detected approach course. Thus, in response to the detected distance of the vehicle from the light signal, the emission lobe projected for this distance or distance range can be used.

In wartungsarmer Weise können die einzelnen Leuchtelemente der Leuchtpunkte LED-Lichtpunkte sein.In a low-maintenance manner, the individual light elements of the light points can be LED light points.

In vorteilhafter Weise werden zur Bestimmung der massgeblichen Abstrahlkeule ein Aufstellungsort des Lichtsignals sowie eine Topologie des Verkehrsweges berücksichtigt.In an advantageous manner, a location of the light signal and a topology of the traffic route are taken into account in order to determine the relevant emission lobe.

In einer weiteren vorteilhaften Ausgestaltung der vorliegenden Erfindung können der Aufstellungsort des Lichtsignals und die Topologie des Verkehrsweges in einem Tool graphisch dargestellt werden, wobei eine massgebliche Abstrahlkeule und/oder ein dynamischer Verlauf von Abstrahlkeulen ebenfalls graphisch im Tool bestimmt werden. Hierzu kann beispielsweise ein berührungssensitiver Bildschirm eines GUI eingesetzt werden, an dem die gewünschte Abstrahlkeule direkt in die dargestellte Gleistopologie eingetragen werden kann.In a further advantageous embodiment of the present invention, the location of the light signal and the topology of the traffic route can be graphically represented in a tool, a relevant radiation lobe and / or a dynamic course of radiation lobes also being determined graphically in the tool. For this purpose, for example, a touch-sensitive screen of a GUI can be used, on which the desired radiation lobe can be entered directly into the track topology shown.

In einer weiteren vorteilhaften Ausgestaltung der Erfindung können die Daten der bestimmten Abstrahlkeule und/oder des bestimmten dynamischen Verlaufs der Abstrahlkeulen zur Programmierung der Ansteuerung der Leuchtelemente verwendet werden, wobei die Daten vorzugsweise aufgrund der graphischen Bestimmung aus dem Tool ausgelesen und in ein Programm zur Ansteuerung der Leuchtelemente übertragen werden. Auf diese Weise kann im Vorfeld eines Bahnanlagenbaus bestimmt werden, welche Abstrahlkeule an einem Lichtsignal optimal ist. Dazu kann mit dem Tool allgemein die Topologie des Verkehrsweges auf dem Bildschirm dargestellt werden. Anhand dieser Darstellung kann die optimale Abstrahlkeule aus einer Reihe von vordefinierten Abstrahlkeulen ausgewählt und bestimmt werden. Die ausgewählte vordefinierte Abstrahlkeule kann dann für einen Leuchtpunkt in der Steuereinheit programmiert werden, worauf die Steuereinheit die einzelnen Leuchtelemente des Leuchtpunktes entsprechend ansteuert.In a further advantageous embodiment of the invention, the data of the specific radiation lobe and / or the specific dynamic course of the radiation lobes can be used to program the control of the light elements, the data preferably being read out of the tool based on the graphic determination and in a program for controlling the Luminous elements are transmitted. This way you can upfront one Railway systems engineering determines which beam is optimal for a light signal. For this purpose, the tool can generally be used to display the topology of the traffic route on the screen. Using this representation, the optimal radiation lobe can be selected and determined from a number of predefined radiation lobes. The selected predefined emission lobe can then be programmed for a luminous point in the control unit, whereupon the control unit controls the individual luminous elements of the luminous point accordingly.

Figur 1 zeigt eine schematische Ansicht von zwei parallel verlaufenden Gleisen 2, 4 und einem Lichtsignal 6 mit drei verschiedenen Abstrahlkeulen 8 (strichpunktierte Linien, 10 (gestrichelte Linien) und 12 (punktierte Linien). Je nach Anwendungsfall kann eine dieser beispielsweise drei Abstrahlkeulen für die Leuchtpunkte des Lichtsignals 6 eingestellt werden. Ein in diesem Sinne adaptierbarer Leuchtpunkt 14 ist in der Figur 2 dargestellt. Der Leuchtpunkt 14 verfügt in der schematisch gezeigten Schnittdarstellung über beispielsweise 15 LED-Leuchtelemente 16.1 bis 16.15, die beispielhaft in drei Gruppen von je fünf LED-Leuchtelementen zusammengefasst sind, wobei jede Gruppe von LED-Leuchtelemente in eine andere Richtung abstrahlt. Jedes der LED-Leuchtelemente 16.1 bis 16.15 verfügt über eine eigene Versorgungsleitung 18.1 bis 18.15, so dass jedes LED-Leuchtelement 16.1 bis 16.15 von einer Steuereinheit 20 individuell angesteuert werden kann. Durch diese individuelle Ansteuerung sind die verschiedenen Abstrahlkeulen 8 bis 12 darstellbar. Die Steuereinheit 20 wird hierzu entsprechend programmiert, was durch einen Pfeil 22 angedeutet ist. Dabei muss die Ansteuerung des Leuchtpunktes 14 der eisenbahntechnisch geforderten Sicherheit genügen, damit sichergestellt ist, dass es nicht zu unbeabsichtigten Veränderungen der Abstrahlkeule kommen kann. Figure 1 shows a schematic view of two parallel tracks 2, 4 and a light signal 6 with three different radiation lobes 8 (dash-dotted lines, 10 (dashed lines) and 12 (dotted lines). Depending on the application, one of these can, for example, three radiation lobes for the light points of the Light signal 6. A luminous point 14 adaptable in this sense is shown in FIG Figure 2 shown. In the sectional illustration shown schematically, the luminous point 14 has, for example, 15 LED luminous elements 16.1 to 16.15, which are exemplified in three groups of five each LED lighting elements are combined, each group of LED lighting elements emitting in a different direction. Each of the LED lighting elements 16.1 to 16.15 has its own supply line 18.1 to 18.15, so that each LED lighting element 16.1 to 16.15 can be controlled individually by a control unit 20. The various radiation lobes 8 to 12 can be displayed through this individual control. The control unit 20 is programmed accordingly for this purpose, which is indicated by an arrow 22. In this case, the control of the luminous point 14 must meet the safety required by the railway, so that it is ensured that there cannot be unintentional changes to the radiation lobe.

Bei dem in Figur 1 gezeigten Ausführungsbeispiel wäre es auch möglich die drei Abstrahlkeulen 8 bis 12 nacheinander in Reaktion auf die Annäherung eines Schienenfahrzeugs darzustellen. Hierfür sind am Gleis 2 beispielhaft drei Sensoren 24 bis 28 angeordnet, die die Annäherung des Schienenfahrzeug detektieren und so die Abstrahlkeulen 8, 10 und 12 der Reihe nach schalten. Hierzu steuert die Steuereinheit 20 nach empfangenen Annäherungssignal die entsprechenden Abstrahlkeulen 8 bis 12. Grundeingestellt ist die Abstrahlkeule 8. Spricht der Annäherungssensor 26 an, wird die Abstrahlkeule 10 durch entsprechende Ansteuerung der LED-Leuchtelemente 16.1 bis 16.15 abgestrahlt. Entsprechend wird bei Ansprechen des Annäherungssensors 28 auf die Abstrahlkeule 12 umgeschaltet. So ist für den Zugführer immer die seiner aktuellen Position entsprechend als optimal projektierte Sicht auf das Lichtsignal 14 gewährleistet, weil für ihn das Lichtsignal 14 immer mit der als optimal projektierten Abstrahlkeule 8 bis 12 erkenntlich ist.The in Figure 1 The embodiment shown, it would also be possible to display the three radiation lobes 8 to 12 one after the other in response to the approach of a rail vehicle. For this purpose, three sensors 24 to 28 are arranged on track 2, for example, which detect the approach of the rail vehicle and thus switch the radiation lobes 8, 10 and 12 one after the other. For this purpose, the control unit 20 controls the corresponding radiation lobes 8 to 12 after the proximity signal has been received. The basic setting is the radiation lobe 8. If the proximity sensor 26 activates, the radiation lobe 10 is emitted by corresponding control of the LED light elements 16.1 to 16.15. Accordingly, when the proximity sensor 28 responds, a switch is made to the radiation lobe 12. Thus, the driver always has the optimally projected view of the light signal 14 in accordance with his current position, because he can always see the light signal 14 with the optimally projected beam 8 to 12.

Figur 3 zeigt schematisch ein Tool, hier ein Tablett 30, auf dessen berührungssensitivem Display ein Aufstellungsort von Lichtsignalen 32, 34 und eine Topologie der hier gebogenen verlaufenden Gleise 2, 4 graphisch dargestellt werden. Wie dargestellt, greift das Tool 30 hier auf in einer Datenbank hinterlegte Abstrahlkeulen 36 (durchgezogene Linie) und 38 (gestrichelte Linie) zurück. Die gewünschte Abstrahlkeule und/oder ein dynamischer Verlauf von Abstrahlkeulen können dann ebenfalls graphisch mit dem Tool 30 bestimmt werden. Weiter kann auch möglich sein, dass die Begrenzungslinien der Abstrahlkeulen 36, 38 von Hand auf dem Display manipuliert werden können. Diese Veränderungen erkennt das dahinter laufende Programm und setzt sie direkt in entsprechende Daten zur Programmierung der Steuereinheit 20 um. Figure 3 shows schematically a tool, here a tablet 30, on its touch-sensitive display a location of light signals 32, 34 and a topology of the curved tracks 2, 4 graphically being represented. As shown, the tool 30 accesses radiation lobes 36 (solid line) and 38 (dashed line) stored in a database. The desired radiation lobe and / or a dynamic course of radiation lobes can then also be determined graphically with the tool 30. Furthermore, it is also possible that the boundary lines of the radiation lobes 36, 38 can be manipulated by hand on the display. The program running behind recognizes these changes and converts them directly into corresponding data for programming the control unit 20.

Die Daten der bestimmten Abstrahlkeule und/oder des bestimmten dynamischen Verlaufs der Abstrahlkeulen werden so zur Programmierung der Ansteuerung der Leuchtelemente 16.1 bis 16.15 verwendet, wobei die Daten hier aufgrund der graphischen Bestimmung aus dem Tool 30 ausgelesen und in ein Programm zur Ansteuerung der Leuchtelemente an die Steuereinheit 20 übertragen werden. Die Übertragung ist in Figur 3 hierzu mit einem Pfeil 40 angedeutet.The data of the specific radiation lobe and / or the specific dynamic course of the radiation lobes are used to program the control of the light elements 16.1 to 16.15, the data here being read out of the tool 30 based on the graphic determination and transferred to a program for controlling the light elements Control unit 20 are transmitted. The transfer is in Figure 3 this is indicated by an arrow 40.

    c) controlling the diodes (16.1 to 16.15) in order to achieve the predetermined radiation pattern (8, 10, 12, 36, 38), wherein the diodes (16.1 to 16.15) are controlled individually or combined to form groups, wherein a sensor system (24, 26, 28) for detecting a vehicle approaching along the traffic route (2, 4) is provided on the light signal (6), and wherein in response to a detected approaching vehicle, the control unit (20) controls the diodes (16.1 to 16.15) in order to achieve a dynamic sequence of predetermined radiation patterns (8, 10, 12, 36, 38).
  5. Method according to claim 4,
    characterised in that
    a place of installation of the light signal (6, 32, 34) and a topology of the traffic route (2, 4) are taken into account in order to determine the relevant radiation pattern (8, 10, 12, 36, 38).
  6. Method according to claim 5,
    characterised in that
    the place of installation of the light signal (6, 32, 34) and the topology of the traffic route (2, 4) are shown graphically in a tool (30), wherein a relevant radiation pattern (8, 10, 12, 36, 38) and/or a dynamic course of radiation patterns (8, 10, 12, 36, 38) are likewise determined graphically in the tool (30).
  7. Method according to claim 5 or 6,
    characterised in that
    the data of the determined radiation pattern (8, 10, 12, 36, 38) and/or the determined dynamic course of the radiation patterns (8, 10, 12, 36, 38) are used to programme the control of the diodes (16.1 to 16.15), wherein on account of the graphical determination the data is preferably read out from the tool (30) and transmitted into a program to control the diodes (16.1 to 16.15).
