Die Erfindung betrifft ein Verfahren zur Steuerung einer 65 man die gegen das Tunneleinfahrtsportal gerichtete Leucht-Tunnelbeleuchtungsanlage, bei welchem man die Leuchtdich- dichtemessung in zeitlichen Abständen mehrmals wiederholt, te misst und anhand des resultierenden Messergebnisses min- anhand der einzelnen Messergebnisse einen Leuchtdichte-destens die in der zugewandten Tunneleinfahrtszone angeord- Mittelwert berechnet und aus diesem einen Leuchtdichtesoll- The invention relates to a method for controlling a luminous tunnel lighting system directed towards the tunnel entrance portal, in which the luminous density measurement is repeated several times, at intervals, and measured, and based on the resultant measurement result, at least one luminance, based on the individual measurement results arranged in the facing tunnel entrance zone - calculated mean value and from this a luminance target
Mittelwert für die Tunneleinfahrtszone festlegt, und anhand des letzteren mindestens die in der zugewandten Tunneleinfahrtszone angeordnete Tunnelbeleuchtung steuert. Dabei ist es zweckmässig, wenn man in der Tunneleinfahrszone in zeitlichen Abständen mehrmals die Leuchtdichte bestimmt, anhand dieser einzelnen Messergebnisse einen Einfahrszonen-leuchtdichte-Mittelwert für die Tunneleinfahrtszone berechnet und bei einer Überschreitung einer vorbestimmten Differenz zwischen einem entsprechend festgelegten Leuchtdichtesoll-Mittelwert und dem Leuchtdichte-Mittelwert für die Tunneleinfahrtszone die Tunnelbeleuchtung in letzterer in korrigierendem Sinne reguliert. Specifies the mean value for the tunnel entrance zone and controls at least the tunnel lighting arranged in the facing tunnel entrance zone on the basis of the latter. It is expedient if the luminance in the tunnel entry zone is determined several times at intervals, calculates an entry zone luminance mean value for the tunnel entry zone on the basis of these individual measurement results and if a predetermined difference between a correspondingly determined nominal luminance target value and the luminance value is exceeded. Average value for the tunnel entrance zone regulates the tunnel lighting in the latter in a corrective sense.
Es ist ausserdem vorteilhaft, wenn man die Leuchtdichte in der Tunnelmittelzone in zeitlichen Abständen mehrmals misst, daraus einen Ist-Mittelwert berechnet, diesen letzteren mit einem auf Grund der Verkehrsdichte und/oder Sichtweite vergleicht, und bei einer Überschreitung einer vorbestimmten Differenz die Beleuchtungsstärke der Tunnelmittelzone entsprechend reguliert. It is also advantageous if the luminance in the central tunnel zone is measured several times at intervals, from which an actual mean value is calculated, the latter is compared with one based on the traffic density and / or visibility, and if a predetermined difference is exceeded, the illuminance of the central tunnel zone regulated accordingly.
Gegenstand der vorliegenden Erfindung ist ferner eine Einrichtung zur Durchführung des erfindungsgemässen Verfahrens, welche dadurch gekennzeichnet ist, dass die Leuchtdichtemesseinrichtung eine das auszumessende Blickfeld auf die Kugelinnenwand einer Ulbricht'schen Kugel abbildende Optik sowie mindestens eine in das Kugelinnere gerichtete Leuchtdichtemessanordnung aufweist und dass der Kegel des Raumwinkels der Optik im Bereich von 15 bis 30° liegt. The present invention furthermore relates to a device for carrying out the method according to the invention, which is characterized in that the luminance measuring device has an optical system which represents the field of view to be measured on the inside wall of an Ulbricht ball and at least one luminance measuring arrangement directed into the inside of the ball and that the cone of the Solid angle of the optics is in the range of 15 to 30 °.
Dabei ist es zweckmässig, wenn die Optik vorzugsweise aus einem Zoom-Objektiv besteht, und zwischen der Optik und dem Inneren der Ulbricht'schen Kugel eine unerwünschte Teile des Optik-Blickfeldes ausblendende Maske angeordnet ist. It is expedient here if the optics preferably consist of a zoom lens, and a mask that obscures unwanted parts of the optics field of view is arranged between the optics and the interior of the Ulbricht sphere.
Ferner ist es vorteilhaft, wenn die Leuchtdichtemesseinrichtung mit einem vorgeschalteten, ihre Empfindlichkeit an die spektrale Empfindlichkeit des menschlichen Auges anpassenden Filter versehen ist. It is also advantageous if the luminance measuring device is provided with an upstream filter which adjusts its sensitivity to the spectral sensitivity of the human eye.
Eine weitere vorteilhafte Ausgestaltung der Erfindung ist Gegenstand von Anspruch 9. A further advantageous embodiment of the invention is the subject of claim 9.
Nachstehend wird die Erfindung anhand der Zeichnung beispielsweise erläutert. Es zeigt The invention is explained below with reference to the drawing, for example. It shows
Fig. 1 schematisch die Tunneleinfahrtsverhältnisse, 1 schematically shows the tunnel entrance conditions,
Fig. 2 einen Querschnitt durch eine beispielsweise Ausführungsform einer erfindungsgemässen Leuchtdichtemesseinrichtung 2 shows a cross section through an example embodiment of a luminance measuring device according to the invention
Fig. 3 ein Flussdiagramm einer ersten beispielsweise Schaltung zur Steuerung einer Tunnelbeleuchtungsanlage, und 3 shows a flow diagram of a first circuit for controlling a tunnel lighting system, for example, and
Fig. 4 ein Flussdiagramm einer zweiten beispielsweisen Schaltung zur Regelung einer Tunnelbeleuchtungsanlage. Fig. 4 is a flowchart of a second exemplary circuit for controlling a tunnel lighting system.
Wie aus Fig. 1 ersichtlich, werden die Tunneleinfahrtsverhältnisse in eine Tunnel-Annäherungszone A, eine Tunnel-Einfahr- oder Übergangszone E und eine Tunnel-Mittelzone M unterteilt. As can be seen from FIG. 1, the tunnel entrance conditions are divided into a tunnel approach zone A, a tunnel entry or transition zone E and a tunnel middle zone M.
Wenn ein Automobilist sich einem unbeleuchteten Tunnel nähert und durch das Portal in den Tunnel einfahrt, durchfahrt er Zonen mit grossen Helligkeitsunterschieden, und dies meistens schneller, als sich sein Auge daran anpassen kann. Deshalb ist im allgemeinen im Tunnelinnern eine Beleuch- When an automobile driver approaches an unlit tunnel and enters the tunnel through the portal, he drives through zones with large differences in brightness, usually faster than his eye can adapt to it. This is why there is generally a

tung vorgesehen, die eine entsprechend der erlaubten Fahrzeuggeschwindigkeit genügende Sicht ermöglicht. device provided, which enables a sufficient view according to the permitted vehicle speed.
Auch wenn das Fahrzeug sich noch vor dem Tunnel befindet, muss sein Fahrer in den Tunnel hinein sehen können, zu-5 mindest auf die Länge seiner Anhaltestrecke. Diese Strecke wird die Einfahrtzone genannt und benötigt die hellste Beleuchtung. Mit zunehmender Anpassung des Auges an die im Tunnel vorhandene Helligkeit kann die Beleuchtung gegen das Innere abnehmen, was in den Übergangszonen erfolgt, io Die Helligkeit der Beleuchtung im inneren Teil des Tunnels der Mittelzone wird bestimmt durch die zulässige Fahrgeschwindigkeit, ob Gegenverkehr vorhanden ist und den veränderlichen Grössen, Sichtweite und Verkehrsdichte, aber nicht mehr durch die Helligkeit im Freien. Even if the vehicle is still in front of the tunnel, its driver must be able to see into the tunnel, at least for the length of its stopping distance. This route is called the entry zone and requires the brightest lighting. With increasing adaptation of the eye to the brightness in the tunnel, the lighting towards the interior can decrease, which takes place in the transition zones, io The brightness of the lighting in the inner part of the tunnel in the middle zone is determined by the permissible driving speed, whether there is oncoming traffic and the variable sizes, visibility and traffic density, but no longer due to the brightness outdoors.
i5 Die Beleuchtung eines Tunnels soll also für die Einfahr-und Übergangszonen nach der Aussenhelligkeit und für die Mittelzone nach von der Aussenhelligkeit unabhängigen Kriterien geführt werden. i5 The lighting of a tunnel should therefore be controlled for the entry and transition zones according to the outside brightness and for the central zone according to criteria independent of the outside brightness.
Wie aus Fig. 1 ersichtlich, ist am Beginn der Annähe-2orungszone A eine erste Leuchtdichtemesseinrichtung 1 angeordnet, welche innerhalb eines gegen das Tunneleinfahrtsportal P gerichteten Blickfeldes von 20° die Aussenleuchtdichte LA misst. As can be seen from FIG. 1, a first luminance measuring device 1 is arranged at the beginning of the proximity zone A, which measures the outside luminance LA within a field of view of 20 ° directed against the tunnel entrance portal P.
Ferner ist im Anfangsbereich der Einfahrzone eine zweite 25 ins Tunnelinnere gerichtete Leuchtdichtemesseinrichtung 2 zur Bestimmung der Ist-Einfahrzonenleuchtdichte LE und in der Tunnel-Mittelzone M eine dritte Leuchtdichtemesseinrichtung 3 zur Bestimmung der Ist-Mittelzonenleuchtdichte LM angeordnet. Furthermore, a second 25 luminance measuring device 2 directed into the tunnel interior for determining the actual entry zone luminance LE and in the center tunnel zone M a third luminance measuring device 3 for determining the actual middle zone luminance LM are arranged in the beginning area of the entry zone.
30 Die Leuchtdichtemesseinrichtungen 1,2 und 3 sind zum Beispiel wie aus Fig. 2 ersichtlich, ausgebildet, indem sie ein das auszumessende Blickfeld auf die Kugelinnenwand einer Ulbricht'schen Kugel 4 abbildendes Zoomobjektiv 5 aufweisen, welch letzteres es erlaubt, den Blickwinkel den örtlichen 35 Bedürfnissen anzupassen, die durch Unterschiede in der Topographie gegeben sein können. The luminance measuring devices 1, 2 and 3 are designed, for example, as can be seen in FIG. 2, by having a zoom lens 5 which depicts the field of view to be measured on the inner wall of an Ulbricht sphere 4, the latter allowing the viewing angle to be local 35 Adapt to needs that may arise from differences in topography.
Mit Hilfe einer zwischen dem Zoom-Objektiv 5 und dem Innern der Ulbricht'schen Kugel 4 angeordneten Maske 6 können Teile des Blickfeldes, zum Beispiel der Gegenverkehr, 40 welche einen unerwünschten Einfluss auf das Messergebnis hätten, ausgeblendet werden. With the aid of a mask 6 arranged between the zoom lens 5 and the inside of the Ulbricht sphere 4, parts of the field of view, for example oncoming traffic, which would have an undesirable influence on the measurement result, can be masked out.
Im Innern der Ulbricht'schen Kugel 4 wird ein homogenes Leuchtdichtefeld erzeugt, das mit Hilfe einer Fotodiode 7 gemessen wird. Ein der letzteren vorgeschaltetes Filter 8 be-45 wirkt eine spektrale Anpassung der Fotodiode 7 an die spektrale Empfindlichkeit des menschlichen Auges. A homogeneous luminance field is generated in the interior of the Ulbricht sphere 4 and is measured with the aid of a photodiode 7. A filter 8 be-45 connected upstream of the latter effects spectral adaptation of the photodiode 7 to the spectral sensitivity of the human eye.
In einer in Fig. 3 dargestellten einfachen Ausführung einer Tunnelbeleuchtungsanlage ist nur eine Steuerung derselben vorgesehen. In a simple embodiment of a tunnel lighting system shown in FIG. 3, only one control thereof is provided.
50 Bei der in Fig. 4 dargestellten Ausführung mit Regelkreis wird der aus der Aussenleuchtdichte LA berechnete Sollwert der Einfahrzonenbeleuchtung mit dem Istwert der letzteren verglichen und die Beleuchtung bei einer Differenz je nachdem entsprechend höher oder niedriger geschaltet, sofern die-55 se Differenz grösser als eine Schaltstufe im Beleuchtungsniveau ist. In the embodiment shown in FIG. 4 with a control circuit, the setpoint value of the entrance zone lighting calculated from the outside luminance LA is compared with the actual value of the latter and the lighting is switched accordingly higher or lower if there is a difference, provided that this difference is greater than one Switching level in the lighting level is.
Das gleiche Verfahren wird für die Tunnelmittelzonenbe-leuchtung angewendet, wobei hier als Führungsgrössen die Verkehrsdichte und die Sichtweite verwendet werden. The same procedure is used for tunnel central zone lighting, with traffic density and visibility being used as reference variables.
