Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Erfassung der Beleuchtungssituation an Verkehrswegen.The The invention relates to a method and a device for detecting the Lighting situation on traffic routes.
Die Erfindung ist insbesondere für selektive Beleuchtungsmessungen an Verkehrswegen einsetzbar und ermöglicht die Überprüfung der Beleuchtungssituation sowie der Funktionstüchtigkeit und der Wirksamkeit von Straßenbeleuchtungen.The Invention is especially for selective illumination measurements can be used on traffic routes and allows verification the lighting situation as well as the functionality and the effectiveness of street lighting.
Zur Beurteilung der Beleuchtung von Fahrbahnen ist es bekannt, die auf der Fahrbahn vorhandene Bestrahlungsstärke zu messen, um eine Information zu den Sichtbedingungen für Verkehrsteilnehmer zu gewinnen.to Assessing the lighting of carriageways it is known on the the roadway existing irradiance to measure an information on the visibility conditions for road users to win.
Aus dem Stand der Technik sind zur Bestimmung der Beleuchtungssituation auf Fahrbahnen verschiedene Verfahren und Anordnungen bekannt.Out The prior art is used to determine the lighting situation Various methods and arrangements are known on lanes.

Um Aussagen über den Beleuchtungszustand zu gewinnen, können die bekannten Methoden zwar auch angewendet werden. Nachteilig ist dabei jedoch, dass der von der Beschaffenheit des Straßenbelags abhängige Reflexionsfaktor ε das Ergebnis beeinflusst, und somit keine eindeutige Aussage über die Parameter und den Zustande der Straßenbeleuchtungseinrichtungen ermöglicht.Around Statements about the lighting condition can win Although the known methods are also used. The disadvantage is However, that of the nature of the road surface dependent reflection factor ε influences the result, and therefore no clear statement about the parameters and allows the state of the street lighting devices.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Anordnung der eingangs genannten Art zu schaffen, der eine Aussage über den Zustand von Fahrbahnbeleuchtungseinrichtungen ermöglicht, die weitgehend unabhängig von störenden Einflüssen ist.Of the Invention is based on the object, a method and an arrangement of the type mentioned above, which makes a statement about enables the condition of roadway lighting devices, largely independent of disturbing influences is.
Erfindungsgemäß wird die Aufgabe mit einem Verfahren, welches die in Anspruch 1 angegebenen Merkmale aufweist, und mit einer Vorrichtung, welche die in Anspruch 6 angegebenen Merkmale enthält, gelöst.According to the invention the object with a method which specified in claim 1 Having features, and with a device, the in claim 6 specified features, solved.
Vorteilhafte Ausgestaltungen sind in den Unteransprüchen angegeben. Gegenstand der Erfindung sind auch Merkmalskombinationen bei denen die in der Beschreibung und/oder in den Ansprüchen angegebenen Einzelmerkmale beliebig miteinander kombiniert werden.advantageous Embodiments are specified in the subclaims. The invention also relates feature combinations in which the specified in the description and / or in the claims Individual features can be combined with each other as desired.
Die Erfindung ermöglicht es, die Art der Beleuchtungskörper sowie Ihre Anzahl und deren Funktion zu ermittelt.The Invention allows the type of lighting fixture as well as their number and their function.
Die erfindungsgemäße Vorrichtung ist vorzugsweise auf einem geeigneten beweglichen System angeordnet, welches die geographische Lage mit einem GPS-System bestimmen kann. Die Vorrichtung enthält ein Kamerasystem, das vorzugsweise aus zwei Kameras besteht, die in Richtung der Beleuchtungskörper ausgerichtet sind. Die Kameras werden vorteilhaft im Sättigungsbereich ihrer lichtempfindlichen Sensoren betrieben, um die Form der Beleuchtungskörper aus deren Umrisskanten ermitteln zu können.The device according to the invention is preferably arranged on a suitable mobile system which can determine the geographical position with a GPS system. The device includes a camera system, which preferably consists of two cameras, which are aligned in the direction of the lighting fixture. The cameras are advantageously operated in the saturation region of their photosensitive sensors to the shape of the To be able to determine lighting fixtures from their outline edges.
Hinter einer definiert lichtdurchlässige Fläche ist ein Leuchtdichtesensor angeordnet, die in Ihrer spektralen und absoluten Durchlässigkeit an die jeweilige Applikation angepasst ist.Behind a defined translucent surface is a Luminance sensor arranged in your spectral and absolute Permeability adapted to the respective application is.
Die erfindungsgemäße Anordnung ermöglicht es, die vorhandene Anzahl von Beleuchtungskörpern, ihre Funktionstüchtigkeit, ihre Leuchtdichte sowie die Beleuchtungssituation auf der Fahrbahn zu erfassen und eine Auswertung unter Berücksichtigung von geographischen Daten zu erstellen.The inventive arrangement allows it, the existing number of lighting fixtures, theirs Functionality, their luminance and the lighting situation to capture on the roadway and considering an evaluation to create geographic data.

Damit ist es möglich, dass die Messanordnung erkennt, ob die Beleuchtung von Na-Dampflampen oder von Hg-Dampflampen oder von Mischsituationen erfolgt. Durch Vergleich mit in einem Speicher hinterlegten Sollwerten können auch Fehler, beispielsweise defekte Lampen, erkannt werden.In order to is it possible that the measuring arrangement detects if the Illumination of Na-vapor lamps or of Hg-vapor lamps or of Mixed situations occurs. By comparison with stored in a memory Setpoints can also be errors, such as defective lamps, be recognized.
