Description

Die Erfindung betrifft ein Verfahren zum Betrieb einer Lichtzeichenanlage zur Steuerung des Straßenverkehrs an Kreuzungen zwischen mindestens einer Straße und mindestens einem Schienenstrang im Bereich einer Straßeneinmündung oder Straßenkreuzung.The invention relates to a method for operating a traffic light system Control traffic at intersections between at least one Road and at least one rail track in the area of one Street junction or intersection.

Zur Sicherung von Bahnübergängen in der Nähe von Straßenkreuzungen oder Straßeneinmündungen gibt es Richtlinien über Abhängigkeiten zwischen der technischen Sicherung von Bahnübergängen und der Verkehrsregelung an benachbarten Straßenkreuzungen oder Straßeneinmündungen (BÜSTRA-Richtlinien), die den Einsatz einer Lichtsignalanlage für den Straßenbereich und einer Lichtsignalanlage für die Sicherung des Bahnüberganges vorschreiben. Die Lichtsignalanlage für den Straßenbereich umfaßt dreibegriffige (Rot-Gelb-Grün) Lichtsignale; für die Lichtsignalanlage zur Sicherung des Bahnüberganges ist ein Rotsignal vorgeschrieben, das gegebenenfalls durch ein gelbes Zusatzsignal ergänzt werden kann. Die Lichtsignale der Anlage für den reinen Straßenbereich, das heißt ohne Sicherung des Bahnüberganges, werden von einer eigenständigen Steuerung gesteuert, in die bei Annähern eines Schienenfahrzeuges eingegriffen wird, um eine Räumung des Bereiches des Bahnüberganges von Straßenfahrzeugen zu ermöglichen und rechtzeitig mittels der separaten Lichtsignalanlage für die Sicherung des Bahnüberganges das Rotsignal der separaten Bahnübergangs-Lichtsignalanlage einzuschalten. Die Sicherung des Bahnüberganges kann zusätzlich zum Rotsignal der hierfür vorgesehenen Lichtsignalanlage durch Schranken, gegebenenfalls Halbschranken ergänzt werden. To secure level crossings near road crossings or Junctions there are guidelines on dependencies between the technical security of level crossings and traffic regulations neighboring intersections or junctions (BÜSTRA guidelines), the use of a traffic light system for the street area and prescribe a traffic light system for securing the level crossing. The Traffic light system for the road area includes three terms (red-yellow-green) Light signals; is for the traffic light system to secure the level crossing Red signal prescribed, if necessary by a yellow additional signal can be added. The light signals of the system for the pure street area, that is, without securing the level crossing, are by an independent Control controlled, intervened in the approach of a rail vehicle is to clear the area of the level crossing from To enable road vehicles and timely using the separate Light signal system for securing the level crossing the red signal of the separate level crossing light signal system. Securing the Level crossing can be in addition to the red signal provided for this purpose Traffic light system supplemented by barriers, if necessary half barriers become.

Der Erfindung liegt die Aufgabe zugrunde, bei Lichtzeichenanlagen zur Steuerung des Straßenverkehrs an Kreuzungen zwischen mindestens einer Straße und mindestens einem Schienenstrang im Bereich einer Straßenkreuzung oder Straßeneinmündung den zusätzlichen Aufwand für die zusätzliche Lichtsignalanlage zur Sicherung des Bahnüberganges zu vermeiden, ohne die Sicherheit zu beeinträchtigen.The invention has for its object to avoid the additional effort for the additional light signal system to secure the level crossing in traffic light systems for controlling road traffic at intersections between at least one road and at least one rail track in the area of a road intersection or junction, without compromising safety.

Die Lösung dieser Aufgabenstellung durch die Erfindung ist dadurch gekennzeichnet, daß zur Sicherung des Bahnüberganges die relevanten Rotsignale der Lichtsignalanlage für den Straßenbereich dienen und daß diese Rotsignale jeweils durch einen Mikrocomputer gesteuert werden, der bei Annäherung eines Schienenfahrzeuges die Spannungsversorgung der Rotsignale durch die Steuerung der Lichtsignalanlage für den Straßenbereich überwacht und bei fehlender Spannung die Verbindung der Rotsignale mit der Steuerung der Lichtsignalanlage für den Straßenbereich trennt und die Rotsignale mit Spannung einer von der Lichtsignalanlage für den Straßenbereich unabhängigen Spannungsquelle versorgt.The solution to this problem by the invention is characterized in that the relevant red signals of the light signal system for the road area are used to secure the level crossing and that these red signals are each controlled by a microcomputer which, when a rail vehicle approaches, the voltage supply of the red signals by controlling the light signal system monitors for the road area and disconnects the connection of the red signals with the control of the traffic light system for the road area in the absence of voltage and supplies the red signals with voltage from a voltage source independent of the traffic light system for the road area.

Durch diesen erfindungsgemäßen Vorschlag entfällt die komplette, bisher zusätzlich zur Lichtsignalanlage für den Straßenbereich vorhandene Lichtsignalanlage für die Sicherung des Bahnübergangs, und zwar einschließlich der Fundamente, Masten und Verkabelung; sie wird ersetzt durch die erfindungsgemäßen Mikrocomputer und Schalter für die zur Überwachung des Bahnüberganges relevanten Rotsignale, die in der Steuerung der Lichtsignalanlage für den Straßenbereich untergebracht werden.Through this proposal according to the invention, the complete, hitherto omitted in addition to the traffic light system for the road area Traffic light system for securing the level crossing, including the foundations, masts and wiring; it is replaced by the Microcomputer and switch according to the invention for monitoring the Level crossing relevant red signals that are in the control of the Traffic lights for the street area can be accommodated.

In der Spannungsversorgung der relevanten Rotsignale sowohl durch die gesteuerte Spannung der Lichtsignalanlage für den Straßenbereich als auch durch die unabhängige Spannungsquelle, vorzugsweise die netzausfallgeschützte Spannungsversorgung der Lichtsignalanlage für die Sicherung des Bahnüberganges wird erfindungsgemäß jeweils ein vom Mikrocomputer gesteuertes Schaltbauteil, beispielsweise ein Feldeffekttransistor angeordnet.In the voltage supply of the relevant red signals both through the controlled voltage of the traffic light system for the road area as well the independent voltage source, preferably the protected against power failure Power supply for the traffic light system for securing the Level crossing according to the invention is in each case a microcomputer controlled switching component, for example a field effect transistor.

Gemäß einem weiteren Merkmal der Erfindung ist die Spannung der unabhängigen Spannungsquelle für die Versorgung der relevanten Rotsignalanlage niedriger als die der Lichtsignalanlage für den Straßenbereich, wobei beide Spannungen durch ein elektrisches Bauteil voneinander entkoppelt sind, beispielsweise durch eine Diode. Hierdurch kann auf einfache Weise und mit geringem baulichen Aufwand eine Versorgung der für die Überwachung des Bahnüberganges relevanten Rotsignale der Lichtsignalanlage für den Straßenbereich durch die unabhängige Spannungsquelle erreicht werden.According to a further feature of the invention, the voltage is the independent voltage source for the supply of the relevant Red signal system lower than that of the traffic light system for the street area, whereby both voltages are decoupled from each other by an electrical component are, for example by a diode. This can be done easily and with low construction effort to supply the for monitoring the Level crossing relevant red signals of the traffic light system for the Street area can be reached by the independent voltage source.

Erfindungsgemäß ist die unabhängige Spannungsquelle in Form der Spannungsversorgung der Lichtsignalanlage für die Sicherung des Bahnüberganges immer vorhanden und dient gleichzeitig als Spannungsversorgung für den Mikrocomputer. Hierdurch wird erreicht, daß der Mikrocomputer bei Ausfall der für die Überwachung des Bahnüberganges vorgesehenen Spannung ebenfalls spannungslos wird. Weil hierdurch die Informationen für die Steuerung der Lichtsignalanlage zur Sicherung des Bahnüberganges entfallen, wird dadurch die Störung der Steuerung des Bahnüberganges mitgeteilt. Gleichzeitig wird durch das entsprechende Schaltbauteil auch die Steuerung der Lichtsignalanlage für den Straßenbereich auf Störung geschaltet.According to the independent voltage source in the form of Power supply for the traffic light system for securing the Level crossing always available and also serves as Power supply for the microcomputer. This ensures that the Microcomputer in the event of failure to monitor the level crossing provided voltage is also de-energized. Because this means that Information for the control of the traffic light system to secure the Level crossing is eliminated, this will disrupt the control of the Level crossing communicated. At the same time, the corresponding Switching component also controls the traffic light system for the road area Fault switched.

Zur Weiterbildung der erfindungsgemäßen Lichtzeichenanlage wird mit der Erfindung vorgeschlagen, das jeweilige Rotsignal durch eine Mehrzahl von Leuchtdioden zu bilden, die auf mehrere Reihenschaltungen aufgeteilt sind, die ihrerseits einzeln auf Funktionstüchtigkeit überwacht werden. Bei einer vorteilhaften Ausgestaltung sind sämtliche Leuchtdioden eines Rotsignals in mindestens zwei separat ansteuerbare Gruppen aufgeteilt, so daß bei Ausfall der einen Gruppe die verbleibende zweite Gruppe ausreicht, um die Signalwirkung des Rotsignals zu erfüllen.To further develop the light signaling system according to the invention Invention proposed the respective red signal by a plurality of To form light-emitting diodes, which are divided into several series connections in turn, are individually monitored for functionality. At a In an advantageous embodiment, all the light-emitting diodes of a red signal are in divided at least two separately controllable groups, so that if the one group the remaining second group is sufficient for the signal effect of the Red signal to meet.

Da die Funktion der den Bahnübergang sichernden Rotsignale der Lichtsignalanlage für den Straßenbereich durch die Eisenbahnsignalanlage überwacht wird, wird mit der Erfindung schließlich vorgeschlagen, die zwischen jedem Mikrocomputer und der Steuerung für die Sicherung des Bahnüberganges ausgetauschten Informationen über einen seriellen BUS, beispielsweise CAN zu übertragen.Since the function of the red signals securing the level crossing of the Traffic light system for the road area through the railway signal system is monitored, the invention finally proposes that between every microcomputer and the control system for securing the level crossing exchanged information via a serial bus, for example CAN transfer.

Mit der Erfindung wird schließlich vorgeschlagen, daß die Ansteuerung des Rotsignals durch die Steuerung der Lichtsignalanlage für den Straßenbereich vom Mikrocomputer erfaßt und bei Funktionsuntüchtigkeit des Rotsignals das Schaltbauteil angesteuert wird, welches die Lichtsignalanlage für den Straßenbereich von dem relevanten Rotsignal trennt.With the invention it is finally proposed that the control of the Red signal by controlling the traffic light system for the street area from Microcomputer detects and if the red signal does not work Switching component is controlled, which the light signal system for Separates the road area from the relevant red signal.

In addition to an example of an intersection between a road and a rail track in the area of an intersection, the drawing schematically shows an exemplary embodiment of the traffic light system according to the invention, namely:

a road crossing with a rail track running parallel to the one road,
Fig. 2

the division of the light emitting diodes forming the red signal into two groups.

Die in Fig. 1 gezeichnete Ansicht einer Straßenkreuzung zwischen einer Hauptstraße HS und einer Nebenstraße NS zeigt einen parallel zur Hauptstraße HS verlaufenden Schienenstrang SS, der die Nebenstraße NS im Bereich der Straßenkreuzung kreuzt.The view drawn in Fig. 1 of an intersection between a Main street HS and a side street NS shows one parallel to the main street HS trending track SS, which is the side road NS in the area of Crossroads.

Zur Steuerung des Straßenverkehrs, der außer Kraftfahrzeugen und anderen Fahrzeugen auch Fußgänger und Radfahrer umfaßt, ist für den Straßenbereich eine Lichtsignalanlage vorgesehen, die beim dargestellten Ausführungsbeispiel sechs, jeweils mit einem Rot-, Gelb- und Grünsignal ausgestattete Ampeln A1 bis A6 umfaßt, die von der Steuerung SVA der Straßenverkehrsanlage gesteuert werden. Die Ampeln A1 und A2 dienen hierbei der Steuerung des auf der Hauptstraße HS verbleibenden Verkehrs. Die Ampeln A3 und A4 steuern den von der Hauptstraße HS über den Schienenstrang SS in die Nebenstraße NS abbiegenden Verkehr. Die Ampeln A5 und A6 steuern den in die Kreuzung von der Nebenstraße NS einfahrenden Verkehr.To control road traffic, except motor vehicles and others Vehicles including pedestrians and cyclists is for the road area a light signal system is provided in the illustrated embodiment six traffic lights A1 to, each equipped with a red, yellow and green signal A6 includes that controlled by the controller SVA of the road traffic system become. The traffic lights A1 and A2 are used to control the on the Main road HS remaining traffic. Traffic lights A3 and A4 control the from the main street HS via the rail track SS into the side street NS turning traffic. The traffic lights A5 and A6 drive into the intersection of the Side road NS incoming traffic.

Um den die Nebenstraße NS überquerenden Schienenstrang SS zu sichern, ist eine Steuerung für den Bahnübergang SBÜ vorgesehen, der bisher eine separate Lichtsignalanlage mit Lichtsignalen L1 bis L4 zugeordnet war. Diese beim Ausführungsbeispiel jeweils mit einem Rotlicht und einem Gelblicht ausgestatteten Lichtsignale L1 bis L4 waren den Ampeln A3, A4, A5 und A6 der Lichtsignalanlage für den Straßenbereich zugeordnet, wie dies gestrichelt in Fig. 1 dargestellt ist.To secure the rail track SS crossing the secondary road NS, is a control is provided for the level crossing SBÜ, which was previously a separate one Light signal system with light signals L1 to L4 was assigned. This at Embodiment each equipped with a red light and a yellow light Light signals L1 to L4 were the traffic lights A3, A4, A5 and A6 of the light signal system assigned to the road area, as shown in dashed lines in Fig. 1.

Anstelle dieser in Wegfall kommenden Lichtsignale L1 bis L4 werden bei der in Fig. 1 dargestellten Lichtzeichenanlage die relevanten Rotsignale Rr der Lichtsignalanlage für den Straßenbereich, das heißt die Rotsignale Rr der Ampeln A3, A4, A5 und A6 verwendet. Zusätzlich können auch die entsprechenden Gelbsignale für die Sicherung des Bahnüberganges herangezogen werden.Instead of these light signals L1 to L4, which are no longer available, the in Fig. 1 illustrated light signaling system the relevant red signals Rr Traffic light system for the street area, i.e. the red signals Rr of the traffic lights A3, A4, A5 and A6 used. In addition, the corresponding Yellow signals can be used to secure the level crossing.

In Fig. 2 ist ein derartiges Rotsignal Rr dargestellt, das so lange von der Steuerung SVA der Straßenverkehrsanlage mit Spannung versorgt wird, solange der Verkehr über den Bahnübergang BÜ freigegeben ist. Während dieser Zeit wird der Verkehr im Bereich der Straßenkreuzung ausschließlich über die Steuerung SVA der Straßenverkehrsanlage gesteuert.Such a red signal Rr is shown in FIG SVA of the road traffic system is supplied with voltage as long as the traffic is released via the level crossing. During this time, the traffic in the area of the crossroads only via the SVA control system Road traffic system controlled.

Die Funktionstüchtigkeit aller relevanten Rotsignale Rr durch die Steuerung SVA der Lichtsignalanlage für den Straßenverkehr wird durch jeweils einen dem jeweiligen Rotsignal Rr zugeordneten Mikrocomputer M überwacht. Stellt sich bei dieser Überwachung heraus, daß ein relevantes Rotsignal Rr nicht brennt, das heißt nicht funktionstüchtig ist, wird die Verbindung dieses Rotsignals Rr mit der Steuerung SVA der Lichtsignalanlage für den Straßenbereich unterbrochen. In Fig. 2 ist außer einer zum Mikrocomputer M führenden Überwachungsleitung Ü ein vom Mikrocomputer M gesteuertes Schaltbauteil B1 gezeichnet, welches die Trennung des Rotsignals Rr von der Steuerung SVA der Lichtsignalanlage für den Straßenbereich bewirkt.The functionality of all relevant red signals Rr by the control SVA the traffic light system is replaced by one microcomputer M assigned to the respective red signal Rr. It turns out this monitoring out that a relevant red signal Rr is not burning is not functional, the connection of this red signal Rr with the Control SVA of the traffic light system for the road area interrupted. In Fig. 2 is in addition to a monitoring line Ü leading to the microcomputer M. Switching component B1 controlled by the microcomputer M, which the Separation of the red signal Rr from the control SVA of the light signal system for the Street area causes.

Über eine Diode D ist die Stromversorgungsleitung des Rotsignals Rr an eine von der Straßenverkehrsanlage unabhängige Spannungsquelle angeschlossen, die in Fig. 2 nicht dargestellt ist. Bei dieser Spannungsquelle handelt es sich vorzugsweise um die netzausfallgeschützte Spannungsversorgung für die Sicherung des Bahnüberganges BÜ. Die Spannung dieser unabhängigen Spannungsquelle ist niedriger als die Spannungsquelle der Lichtsignalanlage für den Straßenbereich, so daß ein einfaches elektronisches Bauteil, wie beispielsweise die dargestellte Diode D ausreicht, um die beiden Spannungen voneinander zu entkoppeln und die Spannungsversorgung des relevanten Rotsignals Rr durch die unabhängige Spannungsquelle bei einer Zugfahrt sicherzustellen, wenn die Steuerung SVA der Straßenverkehrsanlage z.B. infolge eines Defektes die Ansteuerung des relevanten Rotsignals Rr nicht übernehmen kann.Via a diode D, the power supply line of the red signal Rr is connected to one of independent power source connected to the road traffic system Fig. 2 is not shown. This is the voltage source preferably around the power failure protected power supply for the Securing the level crossing BÜ. The tension of this independent Voltage source is lower than the voltage source of the traffic light system for the street area, so that a simple electronic component, such as for example, the diode D shown is sufficient to cover the two voltages decouple from each other and the power supply of the relevant Red signal Rr by the independent voltage source during a train journey ensure if the control SVA of the road traffic system e.g. as a result of a defect do not take control of the relevant red signal Rr can.

Die Fig. 2 zeigt weiterhin die Anordnung eines weiteren Schaltbauteils B2 in der Versorgungsleitung des relevanten Rotsignals Rr. Schließlich ist dargestellt, daß der Mikrocomputer M ebenfalls an diese Spannungsversorgung angeschlossen ist. Das Schaltbauteil B1 ist im Regelfall geschlossen. Es wird nur geöffnet, wenn die Steuerung SVA für die Lichtsignalanlage für den Straßenbereich abgekoppelt werden soll, insbesondere wenn durch den Mikrocomputer M die Funktionsuntüchtigkeit des relevanten Rotsignals Rr festgestellt worden ist. Die normale Steuerung des relevanten Rotsignals Rr erfolgt durch das Schaltbauteil B2.2 further shows the arrangement of a further switching component B2 in the Supply line of the relevant red signal Rr. Finally, it is shown that the microcomputer M is also connected to this voltage supply. The switching component B1 is usually closed. It only opens when the SVA control unit for the traffic light system disconnected from the road should be, especially if by the microcomputer M the Inoperability of the relevant red signal Rr has been determined. The The relevant red signal Rr is normally controlled by the switching component B2.

In Fig. 2 ist gezeigt, daß der Mikrocomputer M mit einem seriellen BUS, beispielsweise CAN, verbunden ist, über den sämtliche Informationen zwischen dem Mikrocomputer M und der Steuerung SBÜ für die Sicherung des Bahnüberganges BÜ ausgetauscht werden. Trotz Wegfalls einer separaten Lichtsignalanlage für die Sicherung des Bahnüberganges BÜ erfolgt somit eine vollständige Überwachung der anstelle dieser Lichtsignalanlage verwendeten relevanten Rotsignale Rr zwecks Sicherung des Bahnüberganges BÜ.In Fig. 2 it is shown that the microcomputer M with a serial BUS, for example CAN, via which all information between the microcomputer M and the control SBÜ for securing the Level crossing are exchanged. Despite the omission of a separate one A traffic light system for securing the level crossing is therefore carried out full monitoring of those used instead of this traffic light system relevant red signals Rr for the purpose of securing the level crossing BÜ.

In Fig. 2 ist angedeutet, daß jedes relevante Rotsignal Rr durch eine Mehrzahl von Leuchtdioden LED gebildet wird, die in zwei voneinander unabhängige Gruppen von jeweils 48 Stück aufgeteilt sind. Eine dieser beiden Gruppen von 48 Leuchtdioden LED ist in Fig. 3 dargestellt. Diese Darstellung zeigt, daß die Leuchtdioden LED in mehreren Reihenschaltungen aufgeteilt sind, die ihrerseits einzeln durch eine Stromsensorik S auf Funktionstüchtigkeit überwacht werden. Auf diese Weise ist es möglich, den Ausfall einzelner Leuchtdioden LED in den einzelnen Reihen festzustellen.In Fig. 2 it is indicated that each relevant red signal Rr by a plurality of Light-emitting diodes LED is formed in two independent groups of 48 pieces each. One of these two groups of 48 Light-emitting diodes LED is shown in Fig. 3. This illustration shows that the Light-emitting diodes LED are divided into several series circuits, which in turn are individually monitored for functionality by a current sensor system S. In this way it is possible to prevent the failure of individual light emitting diodes in the LED individual rows.

Durch die Aufteilung des Rotsignals Rr auf zwei separat ansteuerbare Gruppen von beim Ausführungsbeispiel jeweils 48 Leuchtdioden LED gemäß Fig. 2 verbleibt selbst bei Ausfall einer Gruppe eine Restfunktion des Rotsignals Rr, die als Signal ausreicht, um insbesondere die Sicherung des Bahnüberganges BÜ zu gewährleisten. By dividing the red signal Rr into two separately controllable groups of in each case 48 light-emitting diodes LED in the exemplary embodiment according to FIG. 2 Even if one group fails, a residual function of the red signal Rr remains sufficient as a signal, in particular to secure the level crossing level crossing guarantee.

A method as claimed in Claim 1, characterised in that arranged in the voltage supply of the relevant red signals (Rr) both by the controlled voltage of the illuminated signal unit for the road region and also by the independent voltage source, preferably the voltage supply, which is protected against failure of the main supply, of the illuminated signal unit for protecting the railway crossing (BÜ) there is a respective switching component (B1, B2), controlled by the microcomputer (M), for instance a field effect transistor.
  3. A method as claimed in Claim 1 or 2, characterised in that the voltage of the independent voltage source for supplying the relevant red signals (Rr) is lower than that of the illuminated signal unit for the road region and that the two voltages are decoupled from one another by an electrical component (D), for instance a diode.
  4. A method as claimed in one of Claims 1 to 3, characterised in that the independent voltage source in the form of the voltage supply of the illuminated signal unit for protecting the railway crossing (BÜ) is always present and serves simultaneously as the voltage supply for the microcomputer (M).
  5. A method as claimed in at least Claims 1 to 4, characterised in that each red signal (Rr) is constituted by a respective plurality of light emitting diodes (LEDs), which are divided into a plurality of series circuits, which are monitored for their part for their ability to function.
  6. A method as claimed in Claim 5, characterised in that all the light emitting diodes (LEDs) of a red signal (Rr) are divided into at least two separately controllable groups.
  7. A method as claimed in at least one of Claims 1 to 5, characterised in that the information exchanged between each microcomputer (M) and the controller (SBÜ) for protecting the railway crossing (BÜ) is transmitted via a serial BUS, for instance CAN.
  8. A method as claimed in at least one of Claims 1 to 6, characterised in that the control of the red signal (Rr) by the controller of the illuminated signal unit for the road region is detected by the microcomputer (M) and the switching component (B1) is controlled in the event of the inability of the red signal (Rr) to function.
