Description
Die Erfindung bezieht sich auf eine Datenübertragungseinrichtung für Verkehrsleit- und Verkehrsinformationssysteme nach dem Oberbegriff des Patentanspruches 1.The invention relates to a data transmission device for traffic control and traffic information systems the preamble of claim 1.
Aus EP-A-0 25 64 83 ist ein Verkehrsleitsystem bekannt,in dem Leitinformationen zu Fahrzeugen übermittelt werden. Dabei soll die Infrastruktur für ein solches Verkehrsinformationssystem mit möglichst geringem Aufwand geschaffen werden, indem beispielsweise vorhandene Verkehrssignalrechner für Lichtsignalgebersteuerungen mit herangezogen werden. Dafür wird vorgeschlagen, zusätzlich zu einem Lichtsignalgeber, eine Sende- und Empfangseinrichtung, eine sog. Bake, am Lichtsignalmast anzubringen, was mit Aufwand und Anschlußarbeiten und -kosten verbunden ist. Außerdem sind unterschiedliche Techniken zum Betrieb der Lichtsignalgeber und der Sende- und Empfangseinrichtungen notwendig.From EP-A-0 25 64 83 a traffic control system is known in which Guiding information about vehicles are transmitted. there the infrastructure for such a traffic information system can be created with as little effort as possible by for example existing traffic signal calculator for Light signaling controls can also be used. Therefore is proposed, in addition to a light signal transmitter, a Transmitting and receiving device, a so-called beacon, on the light signal mast attach what with effort and connection work and costs are connected. They are also different Techniques for operating the light signal transmitter and the transmitter and Receiving facilities necessary.
Konventionell wird in Lichtsignalgebern farbiges Licht mit einer Glühlampe erzeugt, vor der eine farbige Filterplatte angeordnet ist. Bekannt ist der Effekt, daß aufgrund der Lichtverhältnisse in der Umgebung die farbige Filterplatte auch bei ausgeschalteter Glühlampe scheinbar leuchtet, das heißt nicht deutlich ist, ob das entsprechende Signal an- oder ausgeschaltet ist. Ein weiterer Nachteil bei der Verwendung von Glühlampen besteht darin, daß diese Licht in einem breitbandigem Strahlungspektrum abgeben und nur ein kleiner Prozentsatz in der gewünschten Farbe herausgefiltert und dadurch nur ein Bruchteil der eingesetzten Energie genutzt wird.Colored light is conventionally used in light signal transmitters generated a light bulb in front of a colored filter plate is arranged. The effect is known that due to the Light conditions in the area the colored filter plate Even when the light bulb is switched off, it seems to light up it is not clear whether the corresponding signal is or is switched off. Another disadvantage of using it of incandescent lamps is that these light in one emit broadband radiation spectrum and only a small one Filtered out percentage in the desired color and thereby only a fraction of the energy used becomes.
Aus US-PS-5 457 450 ist bekannt, daß diese Nachteile durch Verwendung von LEDs (Light Emitting Diode) als Strahlungsquelle behoben werden können, da die LEDs nahezu monochromatisches Licht in der gewünschten Farbe produzieren und daher keine Filter benötigen, die die oben beschriebene täuschende Reflexion verursachen können. Außerdem wird bei Verwendung von LEDs fast 100% der erzeugten Energie in Licht der gewünschten Farbe umgesetzt.From US-PS-5 457 450 it is known that these disadvantages are caused by Use of LEDs (Light Emitting Diode) as a radiation source can be resolved because the LEDs are almost monochromatic Produce light in the desired color and therefore don't need filters that are deceptive to the ones described above Can cause reflection. Also, when in use of LEDs almost 100% of the energy generated in the light of the desired Color implemented.
Aufgabe der Erfindung ist es, eine Datenübertragungseinrichtung in Lichtsignalgebern zu entwickeln, die sowohl als Signalgeber als auch für die Übermittlung von Daten geeignet ist und dabei für beide Funktionen eine Ansteuertechnik mit Strompulsen im Hochfrequenzbereich verwendet.The object of the invention is a data transmission device to develop in traffic lights, both as traffic lights as well as for the transmission of data control technology for both functions Current pulses used in the high frequency range.
Die Aufgabe wird bei einer Datenübertragungseinrichtung der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß eine Leuchtdiodenmatrix als Signaleinheit eingesetzt wird, mit den kennzeichnenden Merkmalen des Anspruchs 1.The task is carried out in a data transmission device initially mentioned type solved according to the invention in that an LED matrix is used as the signal unit, with the characterizing features of claim 1.
Die Gruppe der im sichtbaren Bereich emittierenden Leuchtdioden und die Gruppe der im Infrarotbereich emittierenden Leuchtdioden lassen sich dabei separat ansteuern. Ein Vorteil dieser Anordnung gegenüber der herkömmlichen Realisierung von Signalgebern mit ungepulster oder niederfrequenter Stromversorgung und Sendeeinrichtungen mit hochfrequenter Ansteuerung ist die nun mögliche gemeinsame Betriebstechnik, da beide Typen von Dioden mit Strompulsen im Hochfrequenzbereich betrieben werden. Die im sichtbaren Bereich emittierte Lichtleistung läßt sich dadurch leichter regeln, während die Pulse der im Infrarotbereich emittierenden Dioden zur Informationsübertragung codiert werden können. Je nach Ausgestaltung der Erfindung kann die Übertragung der Daten vom Verkehrszentralrechner zur Sendeeinheit dabei über Kabel, durch Infrarotübertragung oder durch Funkübertragung geschehen.The group of light emitting diodes emitting in the visible range and the group of those emitting in the infrared range LEDs can be controlled separately. An advantage this arrangement compared to the conventional realization of Signal generators with unpulsed or low-frequency power supply and transmitters with high-frequency control is the now possible common operating technology, since both types operated by diodes with current pulses in the high frequency range become. The light output emitted in the visible range is easier to control while the pulses the diodes emitting in the infrared range for information transmission can be encoded. Depending on the design the invention can transfer the data from the central traffic computer to the transmitter unit via cable, by infrared transmission or done by radio transmission.
Damit die unter Sicherungsaspekten wichtige Überwachung für das Sperrsignal Rot weiterhin mit der bewährten Technik der Messung des Stroms durch die Glühlampe des Rotlichtes erfolgen kann, wird in einer bevorzugten Weiterbildung der Erfindung das Gelblicht eines Rot-Gelb-Grün-Lichtsignalgebers durch eine Leuchtdiodenmatrix aus gelb emittierenden Leuchtdioden und Infrarotdioden gebildet. Eine solche Anordnung läßt sich dann einfach in bereits vorhandene Lichtsignalgeber integrieren.So that the important security monitoring for the blocking signal red continues with the proven technology of Measurement of the current through the incandescent lamp of the red light can, is in a preferred development of the invention the yellow light of a red-yellow-green light signal transmitter through a light-emitting diode matrix made of yellow-emitting light-emitting diodes and infrared diodes are formed. Such an arrangement can then be easily installed in existing light signal transmitters integrate.
In einer weiteren Ausgestaltung der Erfindung sind neben den im sichtbaren Bereich emittierenden Leuchtdioden und den im Infrarotbereich emittierenden Leuchtdioden auch Photodioden in die Leuchtdiodenmatrix integriert, um Signale von Verkehrsteilnehmern empfangen und an die Verkehrsleitzentrale weiterleiten zu können.In a further embodiment of the invention, in addition to the in the visible range emitting LEDs and in Infrared light emitting diodes also photodiodes integrated into the LED matrix to receive signals from road users received and sent to the traffic control center to be able to forward.
Nachfolgend wird die Erfindung anhand der in den Zeichnungen
dargestellten Ausführungsbeispiele weiter erläutert. Dabei
zeigen
Figur 1 zeigt die Vorderansicht eines Rot-Gelb-Grün-Lichtsignalgebers LS. Rotlicht RL und Grünlicht GL sind dabei wie bekannt durch eine Glühlampe mit Filterscheibe realisiert und nur schematisch dargestellt. Das Gelblicht besteht aus einer Leuchtdiodenmatrix, die sich aus einer großen Anzahl Leuchtdioden SIL (typischerweise 300 - 500) und einer Anzahl Infrarotleuchtdioden IRL (typischerweise 60 - 100) zusammensetzt.Figure 1 shows the front view of a red-yellow-green light signal transmitter LS. Red light RL and green light GL are included realized as known by an incandescent lamp with a filter disc and shown only schematically. The yellow light consists of a light emitting diode matrix made up of a large number Light emitting diodes SIL (typically 300 - 500) and a number Infrared light emitting diodes IRL (typically 60-100).
Die Figur 2 zeigt schematisch im Querschnitt, daß die gelb emittierenden Leuchtdioden SIL gemeinsam an eine elektronische Steuerung ES angeschlossen sind, die über eine Steuereinheit SE mit einer Verkehrsleitzentrale VLZ verbunden ist. Rotlicht RL und Grünlicht GL sind ebenfalls über die Steuereinheit SE mit der Verkehrsleitzentrale VLZ verbunden. Die im Infrarotbereich emittierenden Dioden IRL sind mit einer weiteren Steuerung IS verbunden, die ihrerseits über Datenleitungen DL mit der Steuereinheit SE verbunden ist und die auszusendenden Signale von der Verkehrsleitzentrale VLZ übermittelt bekommt. Durch die Verwendung von hochfrequenten Strompulsen sowohl zum Regeln der ausgesendeten Lichtleistung der im sichtbaren Bereich emittierenden Leuchtdioden, als auch zur Informationsübertragung mit den im Infrarotbereich emittierenden Leuchtdioden lassen sich die elektronische Steuerung ES und die weitere Steuerung IS in vorteilhafter Weise in einer gemeinsamen Technik (beispielsweise einem gemeinsamen ASIC) realisieren.Figure 2 shows schematically in cross section that the yellow emitting light emitting diodes SIL together to an electronic Control ES are connected via a control unit SE is connected to a traffic control center VLZ. Red light RL and green light GL are also via the control unit SE connected to the traffic control center VLZ. The in Infrared emitting diodes IRL are with another Control IS connected, which in turn via data lines DL is connected to the control unit SE and to be sent Signals from the traffic control center VLZ transmitted gets. By using high-frequency current pulses both for regulating the emitted light output of the LEDs emitting in the visible range, as well for information transmission with those emitting in the infrared range LEDs can be used for electronic control ES and the further control IS in an advantageous manner in a common technique (for example, a common ASIC).
Figur 3 zeigt schematisch im Querschnitt wie in der Ausführung nach Fig. 2 die Übertragung der Daten von der Steuereinheit SE zu der weiteren Steuerung IS der im Infrarotbereich emittierenden Dioden durch drahtlose Übertragung ausgeführt wird. Dazu sind sowohl die weitere Steuerung IS mit einer Sende- und Empfangseinheit SIS wie auch die Steuereinheit SE mit einer weiteren Sende- und Empfangseinheit SSE verbunden. Beide Sende- und Empfangseinheiten können nun entweder durch Funk- oder Infrarotübertragung miteinander kommunizieren.Figure 3 shows schematically in cross section as in the embodiment 2 the transmission of data from the control unit SE to the further control IS in the infrared range emitting diodes executed by wireless transmission becomes. For this purpose, both the further control IS with a Transmitting and receiving unit SIS as well as the control unit SE connected to a further transmitting and receiving unit SSE. Both sending and receiving units can now either Communicate with each other via radio or infrared transmission.
