Abstract

Unbemannt fliegende Systeme, die für ihren Antrieb einen oder mehrere Elektromotoren verwenden (s. g. ”Multikopter”), speichern die für Betriebs- und Flugphasen benötigte Energie in Batteriezellen. Zum Aufladen dieser Zellen ist bisher manuell eine Kabelverbindung zwischen der Energiequelle und der Drohne herzustellen. Dieser manuelle Verbindungsvorgang erfordert einen Bediener zum an- und abkoppeln der Kabelverbindung. Die benötigten Steckkontakte sind zudem empfindlich gegen mechanische Einflüsse und können verschmutzen. Das neue Verfahren ermöglicht das kontaktlose Laden der Batteriezellen mittels Induktion. Für die Durchführung eines Ladevorgangs landet die Drohne (1.) auf der Ladestation (2.). In der Ladestation befindet/en sich eine oder mehrere Primärspule/n (3.) die jeweils ein magnetisches Wechselfeld mit einer individuell definierbaren Frequenz erzeugt/en. Die Drohne verfügt ihrerseits über eine oder mehrere Sekundärspule/n, die von dem magnetischen Wechselfeld der Primärspule/n durchdrungen wird. Dadurch wird in der/den Sekundärspule/n eine elektrische Spannung induziert, die zur Aufladung der Batteriezellen dient. Die Batteriezellen regeln mittels Steuerungselektronik den Ladevorgang und kommunizieren über die Drohne mit der Ladestation um den jeweiligen Lade- und Betriebszustand mitzuteilen. Das induktive Laden von Drohnen ist vor allem dort von Vorteil, wo Drohnen ohne Bediener automatisiert Betriebs- und Flugphasen absolvieren sollen, wie zum Beispiel in abgelegenen oder gefährlichen Gebieten. Zudem können Drohnen in Arbeitspausen schnell und selbsttätig elektrische Energie nachladen.Unmanned flying systems that use one or more electric motors (see "Multicopter") for their drive store the energy required for operating and flight phases in battery cells. To charge these cells has been manually establish a cable connection between the power source and the drone. This manual connection procedure requires an operator to connect and disconnect the cable connection. The required plug contacts are also sensitive to mechanical influences and can be dirty. The new method allows the contactless charging of the battery cells by induction. To perform a charge, the drone (1.) lands on the charging station (2.). In the charging station is / s one or more primary coil / s (3.) each of which generates a magnetic alternating field with an individually definable frequency / en. The drone in turn has one or more secondary coil (s) penetrated by the alternating magnetic field of the primary coil (s). As a result, an electrical voltage which serves to charge the battery cells is induced in the secondary coil (s). The battery cells regulate the charging process by means of control electronics and communicate via the drone with the charging station in order to communicate the respective charging and operating state. The inductive charging of drones is particularly advantageous where drones without operator automated to complete operational and flight phases, such as in remote or dangerous areas. In addition, drones can quickly and automatically recharge electrical energy during work breaks.

Description

Unbemannt fliegende Systeme (s. g. ”Drohnen”) die heute für ihren Antrieb zumeist einen oder mehrere Elektromotoren verwenden (s. g. ”Multikopter”), speichern die für ihren Antrieb benötigte elektrische Energie in Batteriezellen, die über eine externe Stromquelle aufgeladen werden. Es ist heute Stand der Technik, dass die Drohne zum aufladen der Batteriezellen in unmittelbarer Nähe einer Stromquelle landen muss, damit ein Bediener manuell eine Kabelverbindung zwischen der Stromquelle und der Drohne herstellt.Unmanned flying systems (see "drones") which today usually use one or more electric motors (see "Multicopter") for their drive, store the electrical energy required for their drive in battery cells, which are charged via an external power source. It is now known in the art that the drone must land in the immediate vicinity of a power source to charge the battery cells for an operator to manually establish a cable connection between the power source and the drone.

Drohnen sind zum nachladen von elektrischer Energie somit auf einen Bediener angewiesen, der manuell eine Verbindung zwischen Energiequelle und Drohne herstellt. Zudem sind die benötigten Steckkontakte empfindlich gegen mechanische Einflüsse und können verschmutzen.Drones rely on an operator to recharge their electrical power, which manually connects the power source to the drone. In addition, the required plug contacts are sensitive to mechanical influences and can pollute.

Diese Probleme werden durch die in Patentanspruch 1.) aufgeführten Merkmale der Vorrichtung und des Verfahrens zu induktiven Stromversorgung von unbemannt fliegenden Systemen gelöst.These problems are solved by the features of the device and the method for inductive power supply of unmanned flying systems listed in claim 1.).

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, dass der für die Herstellung einer Kabelverbindung zwischen Stromquelle und Drohne benötigte Bediener durch ein kontaktloses Verfahren ersetzt wird. Für die Durchführung eines Ladevorgangs landet die Drohne auf der Ladestation. Die benötigte elektrische Energie wird sodann mittels Induktion zwischen der Ladestation und der Drohne übertragen. Dieses Verfahren ist vor allem dort von Vorteil, wo Drohnen ohne Bediener automatisiert Flug- und Einsatzphasen absolvieren sollen. Zudem besteht der Vorteil, dass die Drohnen in Arbeitspausen schnell und selbsttätig Energie nachladen können.The advantages achieved by the invention are, in particular, that the operator required for the production of a cable connection between the power source and the drone is replaced by a contactless method. To perform a charge, the drone lands on the charging station. The required electrical energy is then transmitted by induction between the charging station and the drone. This method is particularly advantageous where drones without operator automated to complete flight and deployment phases. In addition, there is the advantage that the drones can quickly and automatically recharge energy during work breaks.

Eine vorteilhafte Ausgestaltung der Erfindung ist in Patentanspruch 2.) angegeben. Die Ausführung nach Patentanspruch 2.) ermöglicht es, gleichzeitig mehrere Ladekreisläufe zwischen Ladestation und Drohne mit unterschiedlichen Induktionsfrequenzen und Energieübertragungsraten zu betreiben um die Energieversorgung der Drohne variabel und redundant darzustellen.An advantageous embodiment of the invention is specified in claim 2.). The embodiment according to claim 2.) makes it possible to simultaneously operate several charging circuits between charging station and drone with different induction frequencies and energy transfer rates to represent the power supply of the drone variable and redundant.

Eine weitere Ausführung der Erfindung ist in Patentanspruch 3.) angegeben. Die Ausführung nach Patentanspruch 3.) ermöglicht es, die in der Ladestation vorhandene/n Primärspule/n automatisch in optimale Position und Ausrichtung zu bringen. Dabei positioniert die Ladestation die Primärspule/n unabhängig von der Landeposition der Drohne in optimale Position zu der/den Sekundärspule/n in oder an der Drohne. Dieses gewährleistet die Optimierung der induktiven Energieübertragung zwischen Ladestation und Drohne.A further embodiment of the invention is specified in claim 3). The embodiment according to claim 3) makes it possible to bring the present in the charging station / n primary coil / n automatically in optimum position and orientation. The charging station positions the primary coil (s) in the optimal position for the secondary coil (s) in or on the drone, regardless of the landing position of the drone. This ensures the optimization of the inductive energy transfer between charging station and drone.
