Abstract

The display panel in the form of a road traffic sign has a pattern of light emitting diodes, LED's, that are selectively activated to represent different symbols 1a,1b,1c. The LED devices are arranged with different colours appropriate to the different signs. The sign is activated by a built in control unit that monitors the selected symbols and shuts down if an error occurs.

Description

Die Erfindung betrifft eine Anzeigetafel zur Darstellung verschiedener Zeichen und Signale, die für die Verkehrsregelung an Bau- und anderen Gefahrenstellen aufstellbar oder an Fahrzeugen, beispielsweise an Begleitfahrzeugen für Schwer­ lastransporte, angeordnet ist. Dabei erfolgt der erforderliche Zeichenwechsel durch eine unterschiedliche gebündelte Ansteuerung von Leuchtdiodengruppen in einem gemeinsamen Anzeigefeld.The invention relates to a display board for illustration various signs and signals necessary for traffic regulation can be set up at construction sites and other hazardous locations or at Vehicles, for example on escort vehicles for heavy vehicles load transport, is arranged. The necessary is done Character change bundled by a different Control of LED groups in a common Display field.

Aus der Patentliteratur sind eine Vielzahl von Lösungen bekannt, die über eine gesteuerte Anwählung einer Vielzahl einzelner Leuchtdioden (nachfolgend als LED bezeichnet) verschiedene Signale und Zeichen wiedergeben können, so z. B. Dachbalken für Einsatzfahrzeuge der Polizei und Feuerwehr zur Ansteuerung unterschiedlicher Schriftzüge in DE-OS 38 44 572, 38 44 575 und 38 07 684 sowie DE 440 11 819 für die Straßenüberwachung. Dabei ist die Rasterfläche in eine Vielzahl von Rasterpunkten eingeteilt, denen zur Darstellung unterschiedlicher Schriftzüge jeweils einzelne LED zugeordnet sind, die über eine aufwendige Steuer- und Schaltungsanordnung nach dem jeweiligen Erfordernis einzeln aktiviert werden müssen.A variety of solutions are from the patent literature known that a controlled selection of a variety individual light emitting diodes (hereinafter referred to as LED) can reproduce various signals and characters, such. B. Roof beams for police and fire service vehicles Control of different lettering in DE-OS 38 44 572, 38 44 575 and 38 07 684 and DE 440 11 819 for the Road surveillance. The grid area is in a variety divided by halftone dots, for illustration individual LED assigned to different lettering are over a complex control and circuit arrangement be activated individually according to the respective requirement have to.

Weiterhin sind aus DE-OS 26 27 340, EP 704 342 und EP 214594 Lösungen bekannt, die unterschiedliche Zeichen enthalten, die im Wechsel ansteuerbar sind. Dabei sind die Zeichen vorwiegend neben- oder übereinander angeordnet, so daß eine relativ große Anzeigefläche erforderlich ist.Furthermore, from DE-OS 26 27 340, EP 704 342 and EP 214594 Known solutions that contain different characters that can be controlled alternately. The signs are predominant arranged side by side or one above the other, so that a relatively large Display space is required.

Der Erfindung liegt die Aufgabe zugrunde, mittels einer Steuer- und Schalteinrichtung und unter Einsatz ein- oder mehrfarbiger LED verschiedene Zeichen und Signale auf einer Anzeigetafel durch Integrierung verschiedener Zeichen in eine Leuchtfläche zu ermöglichen. Durch Anordnung eines Überwachungs- und Anzeigeteiles ist zu gewährleisten, daß durch Fehlbedienung oder technische Defekte keine Fehlanzeigen auftreten können.The invention has for its object by means of a Control and switching device and using on or multicolored LED different signs and signals on one Scoreboard by integrating different characters into one To enable luminous area. By ordering a Monitoring and display part is to ensure that by Incorrect operation or technical defects do not result in incorrect displays may occur.

Diese Aufgabe wird mit den kennzeichnenden Merkmalen des Hauptanspruches gelöst. Eine weitere vorteilhafte Ausgestaltung der Erfindung ist im Unteranspruch gekennzeichnet.This task is carried out with the characteristic features of the Main claim solved. Another advantageous embodiment the invention is characterized in the subclaim.

Die Erfindung wird im folgenden anhand eines Ausführungsbeispieles näher erläutert. In den zugehörigen Zeichnungen zeigenThe invention is based on a Embodiment explained in more detail. In the associated Show drawings

Fig. 1 eine Übersicht über das Schaltschema, FIG. 1 is an overview of the circuit diagram,

Fig. 2 die Segmentaufteilung für eine Anzeigetafel. Fig. 2 shows the segmentation for a display board.

Die Anzeigetafel 1, die individuell mit verschiedenen ineinander übergehenden Zeichen 1a, 1b, 1c ausgestaltet und mittels ein- oder mehrfarbigen LED ausleuchtbar gestaltet ist, vereinigt in sich in definierten Segmenten die erforderlichen Leuchtflächen. Die einzelnen Zeichen 1a, 1b, 1c sind über ein Steuerteil mit Auswahlschalter 2 und ein Schaltteil 3 durch eine gebündelte Zuschaltung der diesen Leuchtflächen entsprechenden LED, die unmittelbar auf der Anzeigefläche platziert sind, aufrufbar. Durch die jeweilige Kombination der Segmente, die durch eine farblich vorbereitete Leuchtfläche für einfarbige LED oder Verwendung mehrfarbiger LED realisierbar sind, werden die Zeichen und Signale ein- oder mehrfarbig sichtbar. Dabei sind die LED so gebündelt, daß bei sich überschneidenden Teilen verschiedener Zeichen die gleichen LED zum Einsatz kommen. Die Funktionalität der exakten Anzeige auf der Anzeigetafel 1 ist über ein Überwachungsteil 4 auf ein Kontroll- und Anzeigeteil 5 übertragbar, so daß bei Auftreten eines Fehlers die gesamte Anzeigetafel 1 abschaltet und ein gesondertes Lichtsignal auf dem Kontroll- und Anzeigeteil 5 erscheint.The display panel 1 , which is individually designed with different characters 1 a, 1 b, 1 c and which can be illuminated by means of single-color or multi-color LEDs, combines the required luminous areas in defined segments. The individual characters 1 a, 1 b, 1 c can be called up via a control part with selection switch 2 and a switching part 3 by a bundled connection of the LEDs corresponding to these luminous areas, which are placed directly on the display area. The respective combination of the segments, which can be realized with a color-prepared illuminated area for single-color LEDs or the use of multi-color LEDs, makes the signs and signals visible in one or more colors. The LEDs are bundled in such a way that the same LEDs are used for overlapping parts of different characters. The functionality of the exact display on the display panel 1 can be transferred via a monitoring part 4 to a control and display part 5 , so that when an error occurs the entire display panel 1 switches off and a separate light signal appears on the control and display part 5 .

Ein weiteres Ausgestaltungsmerkmal der Erfindung ist die Anordnung von Signalblinkgebern 6, die ebenfalls durch LED beleuchtbar sind und eine zusätzliche Sicherheit für stationär oder transportabel angeordnete Anzeigetafeln bieten. Diese sind ebenfalls über den Steuerteil mit Auswahlschalter 2 wechsel- oder gleichseitig schaltbar.Another design feature of the invention is the arrangement of signal flasher units 6 , which can also be illuminated by LEDs and provide additional security for stationary or transportable display boards. These can also be switched on the control section with selector switch 2, alternating or equilateral.

Der Vorteil der Erfindung liegt darin, daß für die Darstellung unterschiedlicher Zeichen und Signale gegenüber den bisher bekannten Lösungen ein wesentlich geringerer Platzbedarf für die Anzeige eintritt, indem diese Zeichen innerhalb eines begrenzten Anzeigeblockes darstellbar sind. Desweiteren ist ein wesentlich geringerer Aufwand für die Anzeige und die Ansteuerung erforderlich, da die Segmente genau auf die Darstellung der erforderlichen Zeichen und Signale abgestimmt sind.The advantage of the invention is that for the illustration different signs and signals compared to the previous ones known solutions require a much smaller space the ad occurs by placing these characters within a limited display blocks can be displayed. Furthermore is a much less effort for the display and the Control required because the segments are exactly on the Representation of the required signs and signals matched are.

Gegenüber der Anwendung von Lichtleitern ergibt sich der Vorteil, daß die LED unmittelbar auf der Anzeigefläche platziert sind und die Anzeige mit einer spezifisch geringeren elektrischen Leistung möglich ist.Compared to the use of light guides, this results in Advantage that the LED is directly on the display surface are placed and the ad with a specifically lower electrical power is possible.
