Description

Die Erfindung betrifft ein Verfahren zur Steuerung einer Beleuchtungsanlage mit einem Lichtstellpult nach dem Oberbegriff des Anspruches 1.The invention relates to a method for controlling a lighting system with a lighting control panel according to the preamble of claim 1.

Lichtstellpulte dienen zur Steuerung von Beleuchtungsanlagen, wie sie beispielsweise in Theatern und Konzertsälen zum Einsatz kommen. Diese Beleuchtungsanlagen umfassen regelmäßig eine Vielzahl von Beleuchtungseinrichtungen, beispielsweise Bühnenscheinwerfer, wobei die Beleuchtungseinrichtungen vielfach auch noch für sich genommen zwischen einer Vielzahl von Beleuchtungszuständen, beispielsweise unterschiedlichen Farben, unterscheiden können. Diese unterschiedlichen Beleuchtungszustände werden durch programmierte Parameter im Beleuchtungsprogramm des Lichtstellpultes gesteuert. Übliche Beleuchtungsanlagen können dabei bis zu mehrere tausend Beleuchtungseinrichtungen umfassen.Lighting consoles are used to control lighting systems such as those used in theaters and concert halls. These lighting systems regularly include a large number of lighting devices, for example stage spotlights, the lighting devices often also being able to distinguish between a large number of lighting states, for example different colors, on their own. These different lighting states are controlled by programmed parameters in the lighting program of the lighting console. Conventional lighting systems can include up to several thousand lighting devices.

Aus der US 2015/0181676 A1 ist ein Verfahren und ein System zum kontrollierten Beleuchten einer Bühne mit einer Vielzahl an Beleuchtungseinrichtungen bekannt, wobei die Erstellung einer Reihenfolge oder Hierarchie zur Vereinfachung der Steuerung mehrerer Beleuchtungseinrichtungen vorgeschlagen ist.From the US 2015/0181676 A1 a method and a system for the controlled lighting of a stage with a plurality of lighting devices is known, with the creation of a sequence or hierarchy to simplify the control of several lighting devices is proposed.

Mit jeder Beleuchtungseinrichtung kann zumindest ein Lichteffekt, beispielsweise ein Lichtstrahl erzeugt werden, um die Bühne mit diesen Lichteffekten, die sich vielfach überlagern, zu beleuchten. Das gattungsgemäße Verfahren betrifft dabei die Steuerung von Beleuchtungseinrichtungen, die mit zu mindestens einem Stellmotor verstellt werden, um verschiedene Positionierungen der Beleuchtungseinrichtung anfahren zu können. Handelt es sich beispielsweise bei der Beleuchtungseinrichtung um einen Bühnenscheinwerfer, so kann der Lichtstrahl des Scheinwerfers durch Verfahren der entsprechenden Stellmotoren in zwei Achsen frei über die Bühne verschwenkt werden, um beispielsweise dem Hauptdarsteller zu folgen.With each lighting device, at least one light effect, for example a light beam, can be generated in order to illuminate the stage with these light effects, which are often superimposed. The generic method relates to the control of lighting devices that are adjusted with at least one servomotor in order to be able to move to different positions of the lighting device. If, for example, the lighting device is a stage spotlight, the light beam of the spotlight can be freely pivoted over the stage in two axes by moving the corresponding servomotors, in order to follow the main actor, for example.

Aus dem Stand der Technik ist ein Beleuchtungsverfahren bekannt, das als "Move-in Black" bezeichnet wird. Ein derartiges Verfahren ist beispielsweise in einer Anleitung des Unternehmens Horizon Control Inc. offenbart, welche unter folgender URL (Uniform Resource Locator) https://web.archive.org/web/20160402121540/http://www.horizoncontrol. com/mqheIp/general heIp/move in black.htm im Internet abrufbar ist (zuletzt abgerufen am 03. Juli 2018). Bei bekannten "Move-in Black"-Verfahren ist es das Ziel, dass vor dem Anfang einer neuen Positionierung der Beleuchtungseinrichtung der entsprechende Lichteffekt der Beleuchtungseinrichtung vollständig abgeschaltet wird, um zu verhindern, dass die Bewegung des Scheinwerfers während des Anfahrens der nächsten vordefinierten Positionierung vom Zuschauer wahrgenommen werden kann. Das "Move-in Black"-Steuerungskonzept ruht dabei im Wesentlichen auf drei Schritten, Im ersten Schritt wird zunächst die Beleuchtungseinrichtung programmgesteuert abgeschaltet, so dass von der Beleuchtungseinrichtung kein Lichteffekt mehr ausgeht. Anschließend, nach vollständigem Erlöschen der Beleuchtungseinrichtung, wird der Stellmotor vom Lichtstellpult programmgesteuert aktiviert, um mit den Stellmotoren die nächste vordefinierte Positionierung der Beleuchtungseinrichtung anzufahren. Im dritten Schritt wird dann die Beleuchtungseinrichtung nach Erreichen der vordefinierten Positionierung wieder eingeschaltet, um den Lichteffekt zum vorgegebenen Zeitpunkt zu erzeugen. Das Ein- bzw. Abschalten der Beleuchtungseinrichtung kann selbstverständlich auch in der Art eines Abdimmvorganges erfolgen, bei dem die Leuchtstärke der Beleuchtungseinrichtung entlang einer Dimmkurve herunter geregelt beziehungsweise heraufgeregelt wird.A lighting method which is referred to as "move-in black" is known from the prior art. Such a method is disclosed, for example, in instructions from the company Horizon Control Inc., which can be found under the following URL (Uniform Resource Locator) https://web.archive.org/web/20160402121540/http://www.horizoncontrol. com / mqheIp / general heIp / move in black.htm is available on the Internet (last accessed on July 3, 2018). In known "move-in black" methods, the goal is that the corresponding light effect of the lighting device is completely switched off before the start of a new positioning of the lighting device in order to prevent the headlight from moving during the approach to the next predefined positioning Spectators can be perceived. The "move-in-black" control concept is based essentially on three steps. In the first step, the lighting device is initially switched off under program control so that the lighting device no longer emits a light effect. Then, after the lighting device has gone out completely, the servomotor is activated by the lighting control panel under program control in order to be able to use the Servomotors to approach the next predefined positioning of the lighting device. In the third step, the lighting device is switched on again after the predefined positioning has been reached, in order to generate the light effect at the specified time. The lighting device can of course also be switched on and off in the manner of a dimming process, in which the luminosity of the lighting device is regulated down or up along a dimming curve.

Durch das "Move-in Black"-Verfahren werden unerwünschte optische Effekte durch das Verfahren einer Beleuchtungseinrichtung mit eingeschalteter Lichtquelle vermieden. Allerdings kann es auch beim "Move-in Black"-Verfahren zu unerwünschten Beeinträchtigungen der Bühnendarstellung kommen, nämlich durch unerwünschte akustische Störungen. Abhängig von der Bauart der jeweiligen Beleuchtungseinrichtung können nämlich durch den Antrieb der Stellmotoren erhebliche Motorengeräusche entstehen, die bei entsprechend geringerer Umgebungslautstärke die Bühnenshow akustisch beeinträchtigen. Wird zum Beispiel auf einer Theaterbühne in einer Szene ein Monolog eines Schauspielers dargestellt, so ist es im Theatersaal zu dieser Zeit weitgehend still. Wird in einer solchen Monologszene dann ein Bühnenscheinwerfer zur Vorpositionierung in der nächsten vordefinierten Beleuchtungsposition verfahren, so würde dies von den Zuschauern als erhebliche akustische Störung wahrgenommen.The "move-in black" method avoids undesired optical effects caused by the movement of a lighting device with the light source switched on. However, the "move-in-black" method can also lead to undesirable impairments of the stage representation, namely through undesired acoustic disturbances. Depending on the design of the respective lighting device, the drive of the servomotors can cause considerable motor noises which acoustically impair the stage show when the ambient noise is correspondingly lower. If, for example, a monologue by an actor is presented in a scene on a theater stage, it is largely quiet in the theater at this time. If, in such a monologue scene, a stage spotlight is moved to pre-position it in the next predefined lighting position, this would be perceived by the audience as a significant acoustic disturbance.

Aufgabe der vorliegenden Erfindung ist deshalb, ein vorab entwickeltes "Move-in Black"-Verfahren vorzuschlagen, mit dem akustische Störungen durch das Verfahren der Beleuchtungseinrichtungen weitgehend vermieden werden können.The object of the present invention is therefore to propose a previously developed "move-in-black" method with which acoustic interference caused by moving the lighting devices can be largely avoided.

Diese Aufgabe wird durch ein Verfahren nach der Lehre des Anspruches 1 gelöst.This object is achieved by a method according to the teaching of claim 1.

Vorteilhafte Ausführungsformen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the subclaims.

Das erfindungsgemäße Verfahren beruht auf dem Grundgedanken, dass jedem Programmschritt des Beleuchtungsprogramms, die nacheinander abgearbeitet werden, ein Akustikparameter zugeordnet wird. Durch diesen Akustikparameter wird die Geräuschempfindlichkeit des jeweils zugeordneten Programmschrittes charakterisiert. Wird während eines Programmschrittes des Beleuchtungsprogramms beispielsweise eine Monologszene im Theater gespielt, bei der es keinerlei Nebengeräusche gibt, so kann diesem Programmschritt ein Akustikparameter mit hoher Geräuschempfindlichkeit zugeordnet werden. Beispielsweise ist es denkbar, jedem Programmschritt einen Akustikparameter innerhalb einer Wertskala zwischen 1 und 10 zuzuordnen, wobei ein Akustikparameter mit dem Wert 1 einen Programmschritt mit hoher Geräuschempfindlichkeit und ein Akustikparameter mit dem Wert 10 einen Programmschritt mit geringer Geräuschempfindlichkeit definiert. Auf diese Weise können also allen Programmschritten des Beleuchtungsprogramms Akustikparameter zugeordnet werden, die die Geräuschempfindlichkeit der entsprechenden Szene auf der Bühne charakterisieren.The method according to the invention is based on the basic idea that an acoustic parameter is assigned to each program step of the lighting program that are processed one after the other. This acoustic parameter characterizes the noise sensitivity of the respectively assigned program step. If, for example, a monologue scene is played in the theater during a program step of the lighting program, in which there are no background noises, an acoustic parameter with high noise sensitivity can be assigned to this program step. For example, it is conceivable to assign an acoustic parameter to each program step within a range of values between 1 and 10, with an acoustic parameter with the value 1 defining a program step with high noise sensitivity and an acoustic parameter with the value 10 defining a program step with low noise sensitivity. In this way, acoustic parameters can be assigned to all program steps of the lighting program, which characterize the sensitivity to noise of the corresponding scene on the stage.

Während des Programmablaufes zur Durchführung des Beleuchtungsprogrammes ist es dann möglich, alle zwischen den Verfahrensschritten a) und dem Verfahrensschritt c) liegenden Programmschritte im Hinblick auf ihre Akustikparameter zu vergleichen. Die Verstellung der Beleuchtungseinrichtung durch Antrieb mit dem zugeordneten Stellmotor erfolgt dann in Abhängigkeit vom Vergleichsergebnis der verschiedenen miteinander verglichenen Akustikparameter. Dies bedeutet mit anderen Worten, dass nach Abschalten der Beleuchtungseinrichtung die bis zum Wiedereinschalten der Beleuchtungseinrichtung abzuarbeitenden Programmschritte im Hinblick auf ihre Geräuschempfindlichkeit miteinander verglichen werden, wobei durch diesen Vergleich feststellbar ist, in welchem der Programmschritte bevorzugt eine Verstellung der Beleuchtungseinrichtung erfolgen kann, da der entsprechende bevorzugte Programmschritt eine geringe Geräuschempfindlichkeit aufweist. Zuletzt wird die Beleuchtungseinrichtung nach Erreichen der vordefinierten Positionierung wieder eingeschaltet.Erfindungsgemäß ist es vorgesehen, dass die Verstellung der Beleuchtungseinrichtung durch Antrieb mit dem zugeordneten Stellmotor in dem Programmschritt des Beleuchtungsprogramms zwischen Verfahrensschritt a) und Verfahrensschritt c) durchgeführt wird, der den Akustikparameter mit der geringsten Geräuschempfindlichkeit aufweist und somit den bevorzugten Programmschritt darstellt.During the program sequence for carrying out the lighting program, it is then possible to compare all the program steps between process steps a) and process step c) with regard to their acoustic parameters. The adjustment of the lighting device by drive with the associated servomotor then takes place as a function of the comparison result of the various compared acoustic parameters. In other words, this means that after the lighting device has been switched off, the program steps to be processed until the lighting device is switched on again are compared with one another with regard to their sensitivity to noise, whereby this comparison can be used to determine in which of the program steps an adjustment of the lighting device is preferred can take place, since the corresponding preferred program step has a low sensitivity to noise. Finally, the lighting device is switched on again after the predefined positioning has been reached. According to the invention, the adjustment of the lighting device is carried out by drive with the associated servomotor in the program step of the lighting program between method step a) and method step c), which has the lowest acoustic parameter Has sensitivity to noise and thus represents the preferred program step.

Erfolgt die Ansteuerung der Stellmotoren in Abhängigkeit vom Vergleichsergebnis der Akustikparameter der verschiedenen Programmschritte, so kann das zu dem Problem führen, dass dieser Vergleich zu keinem eindeutigen Ergebnis führt, weil beispielsweise alle Akustikparameter gleich sind. In diesem Falle würde das Beleuchtungsprogramm seinen Zweck nicht mehr erfüllen können, da der gewünschte Beleuchtungseffekt dann aufgrund der fehlenden Positionierung nicht mehr erzielbar ist. Um dies in jedem Falle ausschließen zu können, ist gemäß einer bevorzugten Ausführungsform vorgesehen, dass die Verstellung der Beleuchtungseinrichtung durch Antrieb mit den zugeordneten Stellmotor zu einem Zeitpunkt, der um die Verfahrzeit, die zum Anfahren der nächsten Position erforderlich ist, vor dem Zeitpunkt des nächsten programmgesteuerten Einschaltens der Beleuchtungseinrichtung liegt, unabhängig von dem Vergleichsergebnis eingeschaltet wird, Dies bedeutet mit anderen Worten, dass spätestens zu dem Zeitpunkt, der noch genügend Zeit für das Anfahren der nächsten vordefinierten Positionierung lässt, die Stellmotoren eingeschaltet werden, auch wenn das Vergleichsergebnis des zu vergleichenden Akustikparameters nicht zu einem eindeutigen Ergebnis geführt hat. Dadurch wird in jedem Fall die Einhaltung der programmgesteuerten Lichteffekte gewährleistet und gegebenenfalls eine kleine akustische Beeinträchtigung toleriert.If the actuation of the servomotors takes place as a function of the comparison result of the acoustic parameters of the various program steps, this can lead to the problem that this comparison does not lead to a clear result because, for example, all acoustic parameters are the same. In this case, the lighting program would no longer be able to fulfill its purpose, since the desired lighting effect can then no longer be achieved due to the lack of positioning. In order to be able to exclude this in any case, it is provided according to a preferred embodiment that the adjustment of the lighting device by drive with the associated servomotor at a point in time that is the travel time required to move to the next position before the point in time of the next program-controlled switching on of the lighting device is switched on, regardless of the comparison result. In other words, the servomotors are switched on at the latest at the point in time that leaves enough time to move to the next predefined positioning, even if the comparison result of the Acoustic parameter has not led to a clear result. This ensures compliance with the program-controlled lighting effects in any case and, if necessary, tolerates a small acoustic impairment.

Bei einem programmgesteuerten Ablauf entsprechender Beleuchtungsprogramme werden die Beleuchtungseinrichtungen programmgesteuert abgeschaltet beziehungsweise eingeschaltet. Die Lichtszenen sind dabei in einzelnen Beleuchtungsschritten vordefiniert, die programmgesteuert nacheinander ablaufen. Um den Benutzer des Lichtstellpults die Möglichkeit zu geben, für einzelne Programmschritte eine Verstellung der Beleuchtungseinrichtung zwingend auszuschließen, können die entsprechenden Programmschritte im Programmablauf derart gekennzeichnet werden, dass die Verstellung der Beleuchtungseinrichtung durch Ansteuerung des zugeordneten Stellmotors in diesem Programmschritt unabhängig vom Vergleichsergebnis der miteinander zu vergleichenden Akustikparameter ausgeschlossen ist,In the case of a program-controlled sequence of corresponding lighting programs, the lighting devices are switched off or switched on in a program-controlled manner. The light scenes are predefined in individual lighting steps that run one after the other under program control. In order to give the user of the lighting control desk the possibility of absolutely excluding an adjustment of the lighting device for individual program steps, the corresponding program steps in the program sequence can be marked in such a way that the adjustment of the lighting device by controlling the assigned servomotor in this program step is independent of the comparison result of the Acoustic parameter is excluded,
