Abstract
Description
Satellitenempfangsanlagen bestehend aus einer Satellitenantenne und entsprechenden Empfangseinrichtungen, sind zunehmend auch für den mobilen Einsatz im Gebrauch, z.B. auf Fahrzeugen wie beispielsweise Wohnmobilen. Infolge des mehr oder weniger häufigen Standortwechsels ist es einerseits erforderlich, die in der Regel kleine Satellitenantenne optimal auf den zu empfangenden Satelliten auszurichten, andererseits steht oft keine Netzversorgung für den Betrieb der Satellitenempfangsanlage zur Verfügung.Satellite receivers consisting of a satellite antenna and corresponding Reception facilities are increasingly also for the mobile Use in use, e.g. on vehicles such as motorhomes. As a result of the more or less frequent relocation it is on the one hand required, which is usually small on the satellite antenna On the other hand, there is often no power supply available for the operation of the satellite reception system.
Die DE 198 34 577 A1 zeigt eine spezielle Satellitenantenne bestehend aus vielen kleinen Einzelantennen, die für Wohnmobile dimensioniert ist. Mit Hilfe von GPS kann das gesamte System durch mechanische Drehung in die gewünschte Empfangsrichtung geschwenkt werden.DE 198 34 577 A1 shows a special satellite antenna consisting of many small single antennas, which is dimensioned for campers. With help By GPS, the entire system can be turned into the desired one by mechanical rotation Reception direction are pivoted.
Das Problem der Stromversorgung ist hier nicht angesprochen.The problem of the power supply is not addressed here.
Die DE 42 08 101 A1 zeigt eine stationäre Satellitenempfangsanlage, deren Parabol-Reflektor nicht nur zu dem üblichen Zweck zum Bündeln der auftreffenden Strahlung auf den Brennpunkt ausgelegt ist, sondern bei dem auf dem Parabolspiegel zusätzlich ein photovoltaisches Element aufgebracht ist, das in der jeweiligen Satellitenempfangsposition des Reflektors mehr oder weniger stark auftreffende Tageslicht einem Akkumulator zuleitet, der die elektrische Energie speichert, um diese zur Energieversorgung der Satellitenantenne und der ihr zugeordneten Empfangsbauteile zu verwenden. DE 42 08 101 A1 shows a stationary satellite reception system whose Parabolic reflector not only for the usual purpose of bundling the impinging Radiation is focused on the focal point, but at the the parabolic mirror is additionally applied a photovoltaic element, that in the respective satellite receiving position of the reflector more or less severe incident daylight is directed to a rechargeable battery which discharges the electrical energy stores to these for powering the satellite antenna and the reception components assigned to it.
Diese Lösung hat den Nachteil, dass das photovoltaische Element auf der Reflektorseite unter Umständen die Empfangseigenschaften für das Satellitensignal beeinträchtigt. Die zwangsläufige Ausrichtung der Satellitenantenne auf den Satelliten hat demgemäß zur Folge, dass eine Optimierung der vom photovoltaischen Element abgegebenen Versorgungsleistung nicht möglich ist, sondern nur als Nebenprodukt abfällt.This solution has the disadvantage that the photovoltaic element on the Reflector side may have the reception characteristics for the satellite signal impaired. The inevitable orientation of the satellite antenna Consequently, the satellite has the effect that an optimization of the photovoltaic element delivered power supply not possible is, but only by-product drops.
Bei den in der Regel möglichst gering dimensionierten Empfangs- bzw. Reflektorflächen bei mobilen Satellitenempfangsanlagen bringt diese Lösung keine Vorteile.In the usually small-sized receiving or reflector surfaces at mobile satellite receivers brings this solution no advantages.
Es ist Aufgabe der Erfindung, den Grundgedanken eines Doppelnutzens einer Satellitenantenne, sowohl zur Einspeisung eines Satellitenempfangssignals in den entsprechenden Empfangseinrichtungen, als auch zur Gewinnung von Solarenergie, dahingehend zu optimieren, dass auch die Anwendung auf gering dimensionierte Satellitenantennen, insbesondere für den Bereich der mobilen Anwendung, möglich wird.It is an object of the invention, the basic idea of a double benefit of a Satellite antenna, both for feeding a satellite reception signal in the appropriate receiving facilities, as well as for extraction from solar energy, to optimize that too the application on small-dimensioned satellite antennas, especially for the Range of mobile application, becomes possible.
Erfindungsgemäß wird diese Aufgabe gemäß den Merkmalen des Schutzanspruchs 1 gelöst.According to the invention, this object is achieved according to the features of the patent claim 1 solved.
Der Grundgedanke der Erfindung ist somit darin zu sehen, dass die in der Regel ungenutzte Rückseite der Satellitenantenne zur Aufnahme der Photovoltaikelemente dient und die bei mobilen Satellitenempfangssystemen in der Regel ohnehin vorgesehene Einstellbarkeit des Reflektors zur Maximierung des Empfangssignals dazu benutzt wird, auch eine 2-Achsen-Optimierung der von der Sonne bzw. dem Tageslicht zur Verfügung gestellten Solarenergie zu erreichen. The basic idea of the invention is thus to be seen in the fact that in the Usually unused back of the satellite antenna for receiving the photovoltaic elements serves and which in mobile satellite receiving systems in the Rule anyway provided adjustability of the reflector for maximization the received signal is used, also a 2-axis optimization the solar energy provided by the sun or daylight to reach.
Nach einer vorteilhaften Ausgestaltung kann die Positioniervorrichtung mit einem Navigationsempfänger (z.B. GPS) zusammenarbeiten, dessen Standortdaten sowohl für die Einstellung der Satellitenempfangsposition, als auch für die Einstellung der Sonnenstrahlen-Empfangsposition verwendet werden kann, der insofern also auch eine doppelte Nutzung erfährt.According to an advantageous embodiment, the positioning device with a navigation receiver (e.g., GPS) whose location data both for setting the satellite reception position, as well be used for the adjustment of the sunshine reception position can, therefore, so far, a double use.
Weitere vorteilhafte Ausgestaltungen sind weiteren Unteransprüchen zu entnehmen.Further advantageous embodiments can be found in further subclaims.

Eine Satellitenantenne 10 ist in üblicher Form als Parabolantenne oder Planarantenne
ausgebildet, auf ihrer Rückseite befinden sich mehrere Photovoltaik-Elemente,
die einen Solarmodul 10A bilden, auf ihrer Vorderseite befindet
sich der Reflektor 10B der Empfangsantenne für das Satellitensignal.A
Die Satellitenantenne ist mittels dem oberen Ende 31A eines Bügels 31 mit
dem Reflektor 10B der Satellitenantenne 10 verbunden. The satellite antenna is by means of the
Das untere Ende 31 B des Bügels 31 ist um eine horizontale Schwenkachse
H-H um einen Schwenkwinkel β (Elevationswinkel) auf einer um eine Vertikalachse
V-V drehbaren Dreheinheit 32 befestigt.The
Die Dreheinheit 32 ist als Fußteil ausgebildet, das beispielsweise auf dem
Dach eines Wohnmobils befestigt wird.The
Durch Drehung der Dreheinheit 32 um einen bestimmten Drehwinkel α (Azimutwinkel)
um die Vertikalachse V-V und Schwenkung des Bügels 31 um
einen bestimmten Schwenkwinkel β um die Horizontalachse H-H ist somit
prinzipiell jede Ausrichtung der Antenne auf einen bestimmten Punkt am
Himmel möglich.By rotation of the
In Figur 2 ist die Satellitenantenne in ihrer Ruheposition oder Ablageposition
dargestellt, bei der sie mit der Reflektorseite 10B nach unten geklappt ist und
das Solarmodul 10A nach oben zeigt, die Satellitenantenne befindet sich also
in einer horizontalen Position, bei der zumindest eine vom Sonnenstand abhängige
Gewinnung von Solarstrom durch die Photovoltaik-Elemente des
Solarmoduls 10A möglich ist.In Figure 2, the satellite antenna is in its rest position or storage position
shown, in which it is folded down with the
Figur 3 zeigt die erfindungsgemäße Ausgestaltung zur Einstellung der Satellitenantenne
in Richtung X-X derart, dass das von dem geostationären Satelliten
S ausgesandte Signal die Reflektorfläche 10B derart trifft, dass eine Optimierung
im Sinne einer Maximierung des Empfangssignals eintritt. Diese
erste Position P1 (Satellitenmodus) ist somit durch jeweils einen bestimmten
Wert des Schwenkwinkels β1 um die Horizontalachse H-H und des Drehwinkels
α1 um die Vertikalachse V-V gekennzeichnet.FIG. 3 shows the embodiment according to the invention for adjusting the satellite antenna
in the direction of X-X such that that of the geostationary satellite
S emitted signal hits the
Bei der in Figur 4 dargestellten Position ist das Solarmodul 10A in Richtung
auf die Sonne gerichtet, so dass diese zweite Position P2 (Solarmodus)
durch eine entsprechende Wahl einer Verschwenkung um einen bestimmten
Schwenkwinkel β2 um die Horizontalachse H-H und eine Drehung um einen
bestimmten Drehwinkel α2 um die Vertikalachse V-V gekennzeichnet ist.In the position shown in FIG. 4, the
Die Einstellung der Positionen P1 und P2 kann vorteilhafterweise dadurch
erfolgen, dass der Dreheinheit 32 in einer entsprechenden Steuereinheit ein
Navigationsempfänger zugeordnet ist, der den genauen Standort der Satelittenempfangsanlage
liefert. Ausgehend von diesen Standortdaten, lassen
sich damit anhand entsprechender Tabellen oder Eichwerte die Winkel α1/β1
für die Position P1 im Satellitenmodus d.h., die Ausrichtung auf den zu einem
gewünschten Fernsehsender zugehörigen Satelliten S, als auch durch Wahl
der Winkel α2/β2 die Position P2 im Solarmodus errechnen, und mittels eines
entsprechenden Steuersignals an die Dreheinheit 32 diese um die Vertikalachse
V-V auf den errechneten Zielwinkel α1/ α2 drehen und die Satellitenantenne

Horizontalachse H-H auf den errechneten Zielwinkel β1/ β 2 schwenken.The adjustment of the positions P1 and P2 can advantageously thereby
take place that the
Die entsprechenden Motoren für diese Steuerung sind in den Zeichnungen nicht dargestellt.The corresponding motors for this control are in the drawings not shown.
Anhand der vom Navigationsempfänger gelieferten Positionsdaten ist es mit geeigneten Formeln in der Software der Empfangselektronik ohne weiteres möglich, einen automatischen Satellitenwechsel (mehrere Positionen P1 im Satellitenmodus) vorzunehmen.Based on the position data supplied by the navigation receiver it is with suitable formulas in the software of the receiving electronics readily possible, an automatic satellite change (several positions P1 in Satellite mode).
In der Position P2 (Solarmodus) kann anhand entsprechender Tabellen oder Eichwerte auch eine automatische Nachführung der Satellitenantenne relativ zur Sonne, beispielsweise in Minutenschritten, durchgeführt werden, wobei durch die Nutzung des Navigationsempfängers auch für diesen Zweck spezielle Sonnen- oder Helligkeitssensoren nicht mehr erforderlich sind.In the position P2 (solar mode) can be calculated using appropriate tables or Calibration values also an automatic tracking of the satellite antenna relative to the sun, for example, in minute steps, are performed by using the navigation receiver also for this purpose special Sun or brightness sensors are no longer required.
Besonders vorteilhaft bei der erfindungsgemässen Konzeption ist, dass die Nutzungsperioden des Satellitenmodus und des Solarmodus, die weitgehend den Tageszeiten entsprechen, nur wenig überlappen, so dass auch in diesem Sinne eine sehr wirtschaftliche Gesamtlösung im Sinne einer durchgängigen Nutzung der Satellitenantenne gefunden wurde.Particularly advantageous in the inventive concept is that the Use periods of the satellite mode and the solar mode, which largely correspond to the times of day, overlap only slightly, so that too in this Meaning a very economical overall solution in the sense of an integrated one Use of the satellite antenna was found.
