Die optimale Ausrichtung von solartechnischen Einrichtungen, wie z.B. von Solarmodulen oder Solarkollektoren, zur Sonne wird bisher beispielsweise mittels komplexer Rechenmodelle bewerkstelligt, die orts- und tageszeitabhängig über Datentabellen die optimale Ausrichtung ermitteln.The optimal alignment of solar technology equipment, such as of solar modules or solar panels, the sun so far, for example accomplished by means of complex computational models that depend on location and time of day over data tables determine the optimal alignment.

Die Nachteile der oben genannten Lösungen sind, dass sie eine große Rechenleistung voraussetzen oder einen relativ großen Aufbau benötigen, um eine optimale Signalstärke bzw. einen ausreichenden Antriebsstrom zu erreichen.The Disadvantages of the above-mentioned solutions are, that she is a big one Require computing power or a relatively large structure need, for optimal signal strength or to achieve a sufficient drive current.
Die zu Grunde liegende Aufgabe der Erfindung ist es deshalb ein kompakt aufgebautes Messgerät zur Messung eines Lichteinfallswinkels sowie eine geregelte Nachführeinrichtung bereitzustellen, die zuverlässig solartechnische Einrichtungen optimal zur Sonne hin ausrichtet.The underlying object of the invention is therefore a compact built-up measuring device for measuring a light incidence angle and a controlled tracking device to provide that reliable Solar equipment optimally aligned to the sun.
Diese Aufgabe wird durch die unabhängigen Ansprüche der vorliegenden Erfindung gelöst. Die abhängigen Ansprüche sind vorteilhafte Ausgestaltungen der Erfindung.These The object is achieved by the independent claims of solved present invention. The dependent ones claims are advantageous embodiments of the invention.
Gemäß einem ersten Aspekt der Erfindung wird ein Messgerät zum Messen eines Lichteinfallswinkels bereitgestellt. Das Messgerät weist mindestens zwei winkelig zueinander angeordnete lichtempfindliche Sensoren auf. Als Sensoren sind insbesondere Fotowiderstände geeignet. Allerdings ist auch die Verwendung von Fotodioden oder allgemein gesprochen die Verwendung jeglicher Sensoren geeignet, die ein zur Lichteinstrahlung zumindest abschnittsweise proportionales Ausgangssignal liefern. Mittels einer Messeinrichtung werden die Ausgangssignale der lichtempfindlichen Sensoren verglichen. Das Verhältnis der Ausgangssignale zueinander spiegelt den Lichteinfall wieder, denn durch die winklige Anordnung der lichtempfindlichen Sensoren zueinander ist nur dann die Differenz der Ausgangssignale annähernd null, wenn die lichtempfindlichen Sensoren mit der Lichteinfallsrichtung im Wesentlichen den gleichen Winkel einschließen. Abhängig davon welcher lichtempfindliche Sensor das höhere Ausgangssignal ausgibt, kann somit der Lichteinfallswinkel bestimmt werden. Darüber hinaus sind die lichtempfindlichen Sensoren über Abschirmungseinrichtungen, d.h. beispielsweise mittels Hülsen um die Fotowiderstände, abgeschirmt. Dadurch wird der Lichteinfall auf die lichtempfindlichen Sensor begrenzt. D.h. auch bereits bei einer geringfügigen winkeligen Anordnung der lichtempfindlichen Sensoren zueinander ist durch die Abschirmeinrichtung das Ansprechverhalten der Sensoren derart verbessert, dass eine Anordnung der Sensoren unter kleinem Winkel mit wenig Abstand zueinander verwirklicht werden kann.According to one The first aspect of the invention is a measuring device for measuring a light incidence angle provided. The measuring device has at least two angularly arranged photosensitive Sensors on. As sensors in particular photoresistors are suitable. However, the use of photodiodes or general is also said the use of any suitable sensors, the one to Light irradiation at least partially proportional output signal deliver. By means of a measuring device, the output signals compared to the photosensitive sensors. The ratio of Output signals to each other reflects the light incidence, because by the angular arrangement of the photosensitive sensors to each other if only the difference of the output signals is approximately zero, when the photosensitive sensors with the light incident direction include substantially the same angle. Depending on which photosensitive Sensor the higher output signal Thus, the light incidence angle can be determined. Furthermore are the photosensitive sensors via shielding devices, i.e. for example by means of sleeves around the photoresistors, shielded. As a result, the light is incident on the photosensitive Sensor limited. That even at a slight angle Arrangement of the photosensitive sensors to each other is through the Shielding device improves the response of the sensors such that an arrangement of the sensors at a small angle with little distance to each other can be realized.
Zur Anwendung des erfindungsgemäßen Messgeräts auf dem Gebiet der Nachführeinrichtungen für Sonnenkollektoren oder ähnlichem, ist es erforderlich, mindestens vier lichtempfindliche Sensoren vorzusehen, um Azimut und Elevation der Sonne ermitteln zu können. Die vier lichtempfindlichen Sensoren können beispielsweise an den seitlichen Enden eines flächigen Solarmoduls befestigt sein. Dies ist aber nicht zwingend, so dass auch eine Anordnung gewählt werden kann in der die vier Sensoren direkt nebeneinander angeordnet werden. Diese Anordnungsweise wird insbesondere durch die Abschirmeinrichtungen um die lichtempfindlichen Sensoren unterstützt. Soll eine einfache Kopplung zwischen beispielsweise einem Solarmodul und dem erfindungsgemäßen Messgerät verwirklicht werden, so ist es vorteilhaft das Messgerät, d.h. insbesondere die lichtempfindlichen Sensoren in der Ebene des Solarmoduls anzuordnen. Es kann jedoch auch eine anderweitige mechanische oder elektrische Kopplung zwischen Messgerät und dem Solarmodul vorgesehen sein.to Application of the measuring device according to the invention on the Area of trackers for solar panels or similar, it is necessary to have at least four photosensitive sensors be provided to determine the azimuth and elevation of the sun can. The four photosensitive sensors, for example, to the lateral ends of a flat Be attached solar module. But this is not mandatory, so that also an arrangement chosen can be arranged in the four sensors directly next to each other become. This arrangement is in particular by the shielding supported by the photosensitive sensors. Should a simple coupling realized between, for example, a solar module and the measuring device according to the invention so it is advantageous the meter, i. especially the photosensitive To arrange sensors in the plane of the solar module. It can, however also another mechanical or electrical coupling between gauge and be provided to the solar module.
Ein weiterer Aspekt der Erfindung ist die Anwendung des Messgeräts in einer Nachführeinrichtung zum Ausrichten einer Solareinrichtung auf die Sonne. Unter Solareinrichtung wird hier allgemein jegliches Objekt verstanden, das auf die Sonne ausgerichtet werden soll. Neben Sonnenkollektoren und Solarmodulen können dies z.B. auch Spiegel sein, die das Sonnenlicht auf einen bestimmten Punkt umlenken sollen, wie dies etwa bei Sonnenkraftwerken der Fall ist. Die Nachführeinrichtung verfügt über eine Verstellmechanik zum Drehen der Solareinrichtung um mindestens zwei Raumachsen, wobei das Verstellen um die Raumachsen vorzugsweise von zwei Elektromotoren vorgenommen wird. Die Motoren werden über eine elektrische Regelungseinheit geregelt. Die Regelungseinheit der Nachführeinrichtung erhält Eingangssignale von dem weiter oben erläuterten Messgerät. Die Regeleinrichtung der Nachführeinrichtung und die Messeinrichtung des Messgeräts können durch die gleichen Bauteile integral verwirklicht sein. Beispielsweise kann Regeleinrichtung und Messeinrichtung durch einen Mikrocontroller verwirklicht werden. D.h. es ist möglich, dass Regeleinrichtung und/oder Messeinrichtung analog und/oder digital verwirklicht sind.Another aspect of the invention is the application of the measuring device in a tracking device for aligning a solar device to the sun. Under solar device is generally understood here any object that is to be aligned with the sun. In addition to solar panels and solar modules, these can also be mirrors, for example, which are intended to redirect sunlight to a specific point, as is the case with solar power plants. The tracking device has an adjustment mechanism for rotating the solar device by at least two spatial axes, the adjustment about the spatial axes preferably of two Electric motors is made. The motors are controlled by an electrical control unit. The control unit of the tracking device receives input signals from the measuring device explained above. The control device of the tracking device and the measuring device of the measuring device can be realized integrally by the same components. For example, control device and measuring device can be realized by a microcontroller. That is, it is possible that control device and / or measuring device are implemented analogously and / or digitally.
Das Zusammenspiel von Nachführeinrichtung und Messgerät ergibt sich aus folgendem Wirkprinzip. Die Regelungseinrichtung nimmt ausgehend von einer Ausgangssignaldifferenz eines Paares von lichtempfindlichen Sensoren des Messgeräts die Drehung um eine dem Paar lichtempfindlicher Sensoren zugeordnete Drehachse vor. Dies erfolgt solange, bis die Ausgangssignaldifferenz einen Toleranzwertebereich um null erreicht hat. Der Toleranzwertbereich ist erfindungsgemäß einstellbar und kann somit auf anwendungsbedingte Anforderungen angepasst werden.The Interaction of tracking device and measuring device results from the following principle of action. The control device takes on the basis of an output signal difference of a pair of photosensitive Sensors of the measuring device the rotation about one of the pair of photosensitive sensors associated Rotary axis before. This takes place until the output signal difference has reached a tolerance value range around zero. The tolerance value range is adjustable according to the invention and can therefore be adapted to application-related requirements.
In einer vorteilhaften Ausgestaltung der Erfindung sind die Drehwege um die Raumachsen durch Endanschläge begrenzt. Damit wird der Nachführeinrichtung ein Drehwinkelbereich vorgegeben. Der Drehwinkelbereich kann einstellbar ausgebildet sein. Im Allgemeinen sollte eine Drehung der Solareinrichtung von 180° um eine vertikale Achse und 80° um eine horizontale Achse für Anwendungen in der Solartechnik ausreichend sein. Ein größerer Winkelbereich ist aber verwirklichbar, wenn entsprechende Vorkehrungen in Kabelführung und Verstellmechanik getroffen werden.In an advantageous embodiment of the invention are the rotational paths limited to the spatial axes by end stops. This will be the tracking device a rotation angle range specified. The rotation angle range can be adjusted be educated. In general, should be a rotation of the solar device of 180 ° around a vertical axis and 80 ° around a horizontal axis for Applications in solar technology should be sufficient. A larger angle range but is feasible, if appropriate precautions in cable management and Adjustment mechanism to be taken.
Entsprechend einer weiteren Ausgestaltung der Erfindung weist die Nachführeinrichtung Nachschaltwiderstände für die lichtempfindlichen Sensoren auf, die austauschbar ausgebildet sind. Dadurch kann die Nachführeinrichtung auf die Sonnenintensität bzw. Lichtquellenintensität angepasst werden.Corresponding a further embodiment of the invention, the tracking device Nachschaltwiderstände for the light-sensitive sensors, which are formed exchangeable. This allows the tracking device on the sun intensity or light source intensity be adjusted.
Die Regelung der Nachführeinrichtung erfolgt vorteilhafterweise über einen Mikrocontroller. Es kann ein PIC-Mikrocontroller verwendet werden, wobei ein Analogmultiplexschalter die Ausgangssignale der lichtempfindlichen Sensoren nacheinander an den Mikrocontroller weiterschaltet. Ferner ist eine Schaltung zum Ansteuern der Motoren vorgesehen. Diese weist antiparallel geschalteten Relais zum Ableiten der Abrissinduktionsspannung der Relaiswicklungen auf sowie vier Widerstände an den Endanschlägen.The Regulation of the tracking device takes place advantageously over a microcontroller. It can use a PIC microcontroller be an analog multiplex switch, the output signals of the photosensitive sensors in succession to the microcontroller continue on. Further, a circuit for driving the motors intended. This has anti-parallel connected relay for deriving the demolition induction voltage of the relay windings and four resistors at the end stops.
Die Regelung der Nachführung wird für den Fall der digitalen Regelung über eine Software bewerkstelligt, welche die Differenzen der Ausgangssignale eines Paares lichtempfindlicher Sensoren vergleicht und daraufhin entsprechende Stellsignale für die Motoren errechnet.The Regulation of tracking is for the case of digital regulation over a software accomplishes which the differences of the output signals a pair of photosensitive sensors and then compares corresponding control signals for the Motors calculated.
Die vorliegende Erfindung wird anhand der beiliegenden Zeichnungen detaillierter erläutert.The The present invention will become more apparent from the accompanying drawings explained.
Es zeigt:It shows:
Gut zu erkennen ist anhand dieser Darstellung auch das verbesserte Ansprechverhalten des Messgeräts. Die eingezeichneten Lichtstrahlen auf die Fotowiderstände befinden sich jeweils an Grenzpositionen. Ändert sich der Lichteinfallswinkel nur minimal, so ist durch die winkelige Anordnung der Fotowiderstände im Zusammenspiel mit den Hülsen bereits ein deutlicher Unterschied des jeweils auf die Fotowiderstände einfallenden Lichts gegeben. Dieser Führt zu einem erhöhten Differenzwert, der in einem vorbestimmten Verhältnis zum Lichteinfallswinkel steht.It is also easy to see from this illustration the improved response of the meter. The marked light rays on the photoresistors are located at limit positions. If the angle of incidence of the light changes only minimally, the angular arrangement of the photoresistors in interaction with the sleeves already makes a clear difference in each case to the Photoresistors of incident light given. This leads to an increased difference value, which is in a predetermined relationship to the angle of incidence of light.
