Description

Unmanned aerial vehicle and system for generating fireworks in the airspace

The invention relates to an unmanned aircraft, comprising a drive unit for enabling the flight of the aircraft in the air space and a data processing unit, which is used for driving a position or a chronological sequence of positions of the aircraft

Aircraft in the air space is formed substantially in real time based on position information.

When presenting art or information in the entertainment industry, at public and private events, or in general, it is often desirable to provide an illustration in the airspace. This can be done for example by the use of fireworks. Such firecrackers are fired from the ground manually or controlled by a computer in a certain order.

The development of recent years in the technical field of the unmanned

Aircraft, commonly referred to in the English language as "unmanned aerial vehicle (UAV)", in particular in the field of "drones" or

"Multicopters" have led to the provision of such aircraft

Illustrations in the airspace are used. For example, a large number of UVAs were equipped with LEDs or other bulbs to fly the UVAs with these bulbs in the swarm, where by switching and

Turning off the individual bulbs of the UVAs certain images were created in the airspace.

It would be desirable to be able to populate a UAV with a firework to provide an image in the airspace using this firework. However, this is currently not possible with UVAs according to the state of the art due to a certain hazard potential, since the direction of flight and the explosion of the fireworks body are only conditionally controllable. For example, a gust of wind could twist the UVA in an undesired direction and the firecracker could be shot down into the audience.

The invention has for its object to provide an unmanned aerial vehicle, the security of an image in the air space, which inter alia by the use of fireworks, improves and minimizes the potential danger to viewers, any passers-by, other unmanned aerial vehicles, etc. According to the invention, this object is achieved in that the aircraft at least one holding means for holding at least one fireworks body and a

Activating means for activating the at least one fireworks body, wherein the data processing unit is designed for evaluating and optionally determining at least one security parameter and for controlling the activating means as a function of the at least one security parameter.

By activating the fireworks depending on at least one

For example, safety parameters prevent the fireworks from being activated near humans or other UAVs. In this case, the at least one security parameter expediently has position information and / or time information.

In the example of position information, this may require a

Fireworks is activated only when the UAV is in a specified range of, for example, space or location coordinates. Conversely, this may mean that a firecracker is not activated in a fixed range of, for example, space or location coordinates. Such criteria can be combined. Consequently, it is particularly advantageously prevented by the invention that a fireworks body hits or explodes in the vicinity of a human being, another living being or an object. In the example of time information, this may mean that a firecracker is only activated when a defined time occurs. Conversely, this may mean that a firecracker is not activated before a point in time.

If the at least one safety parameter additionally has a time criterion, the safety parameter and / or the time criterion being designed as a value range with at least one limit value, then the safety can be further increased. For example, the time criterion may be defined as a minimum duration during which a

Fireworks is not activated, so as to exclude short-term changes or influences.

If the aircraft additionally has a communication unit and is the

Data processing unit for receiving and evaluating the position information and the at least one security parameter formed substantially in real time, then the aircraft can be advantageously controlled by an external control device, such as a ground control unit, substantially in real time in the airspace, whereby also the image, ie the fireworks, can be controlled and activated in the airspace essentially in real time.

In an advantageous embodiment of an aircraft according to the invention, the at least one holding means is formed by means of an alignment at least uniaxial, preferably biaxial, rotatably mounted on the aircraft, wherein the

Data processing unit for controlling the alignment of the holding means is formed by means of the alignment means based on alignment information. Thus, the direction of the holding means and consequently the firing direction of the fireworks / s can advantageously be changed while, for example, the aircraft is held at a position in the airspace or from a position in the airspace to a next following position in the airspace

Airspace is moved. It would also be possible to control the flight of the aircraft so that the aircraft is rotated around its own axis until the fireworks point in a direction in the air space into which the fireworks can be shot down safely.

In a particularly advantageous embodiment, the data processing unit is designed to control the activating means as a function of at least two security parameters, wherein a security parameter has alignment information. This may therefore require fireworks to be activated only when the UAV

or the holding means a fixed orientation of example

Has solid angles. Conversely, this may mean that a firecracker is not activated within a fixed range of, for example, solid angles. Consequently, the security is further increased and, inter alia, it is advantageously prevented by a fireworks body being shot down in the direction of a human being, a different living being, an object or a residential area.

All possible applications of one safety parameter or several serial or parallel combined safety parameters are conceivable and may be meaningful. For example, a first safety parameter may have position information, which means, for example, that a fireworks body is activated only within a defined range. A second security parameter having time information can, if the criterion of the first security parameter is met, subsequently start to run, that is, in series with the first security parameter. In this case, for example, a fireworks would be detonated after the UAV

Safety boundary has flown over and a subsequent safety period has expired. However, a second security parameter can also be parallel to a first Safety parameters exist, that is, both criteria must be met simultaneously. This would mean, for example, fireworks being fired only when the UAV stays within a specified range for a certain period of time.

All security parameters, for example the position information, the time information and / or the alignment information, can be combined as desired. Everyone

Safety parameters may have other useful criteria, such as a "sleep criterion", which would require fireworks to be activated only until the legally allowed night's sleep, or, for example, a "protected area criterion", which would require a fireworks not to be in one, on or in the direction of a nature reserve / s or residential area / s is activated.

The aircraft is advantageously designed as a drone, for example as a multicopter. Thereby, the aircraft can be cheaply procured and adapted, and the flight stability and controllability by position information, which may be, for example, three-dimensional GPS coordinates, is accurate, and the aircraft can be held at a position in the airspace substantially indefinitely.

Advantageously, at least one unmanned aerial vehicle according to the invention forms,

or particularly advantageously form a plurality of inventive unmanned aerial vehicles, a system for generating the image in the air space in dependence on at least one security parameter, wherein during a mapping phase the

Figure in the airspace from position information and at least one, is activated by the at least one aircraft activated fireworks depending on the at least one security parameter. In this case, each aircraft additionally advantageously has at least one sensor unit for transmitting distance information to the data processing unit essentially in real time, with each one of them

Data processing unit based on the position information and / or the

Distance information for controlling the aircraft is formed in a swarm composite. As a result, the aircraft are able to capture the picture in the

Airspace completely autonomous without further external control or intervention

while the amount of information that has to be communicated between the aircraft is advantageously reduced. A safety parameter may include the distance information, thereby preventing a different aircraft from being damaged when activating a firecracker and thus additionally increasing the safety of the system. In an advantageous embodiment, at least one aircraft instead of the

By means of an imaging means, in particular a LASER means, an LED means or a display means, wherein the activating means for activating the imaging means and the data processing unit are designed for controlling the activating means. Various effects, such as fireworks and lasers, can be combined to increase the diversity of aerial images.

A system according to the invention for generating an image in the airspace can additionally have a ground control unit which is suitable for storing, processing, transmitting and / or receiving position information of the image and / or the

Security parameter is formed, wherein the ground control unit by means of a

Ground communication unit for communication with the communication units of the aircraft is formed substantially in real time. This allows particularly complex and very large images by means of a large number of

Aircraft, for example 100 or more, can be created in the airspace without the aircraft colliding with each other, with parts of the aircraft or all

Aircraft are controlled externally from the ground control unit.

In the following, the aircraft according to the invention, the system according to the invention and the method according to the invention are explained in a non-restrictive manner with reference to exemplary embodiments shown in the drawings.

Figure 1 shows a perspective schematic view of an unmanned aerial vehicle according to a first embodiment of the invention.

FIG. 2 shows a top view of a plurality of unmanned aerial vehicles according to FIG. 1.

FIG. 3 shows in a perspective schematic view a system for generating an image in the airspace.

FIG. 1 shows an unmanned aerial vehicle 1 according to a first embodiment of the invention. The aircraft 1 is referred to as a drone, more precisely as so-called

"Oktocopter" executed. In this case, a drive unit 2 of the aircraft 1 consists of eight rotor units which are driven, for example, by means of eight electric motors. The drive unit 2 allows the flight of the aircraft 1 in the airspace. An "Okotocopter" is a variant of a "Multicopter" with eight rotor units. The aircraft 1 may alternatively be embodied as another variant of a multi-copter, for example as a "quadcopter" with four rotor units, etc., wherein in principle any number of rotor units is possible Position in the airspace, stabilizable aircraft, be trained (such as zeppelin, balloon, etc.).

The term "airspace" refers to any space above an artificial or natural floor inside or outside an artificial or natural space or building.

The aircraft 1 further has a data processing unit 3, which is designed to control a position or a chronological sequence of positions of the aircraft 1 in the airspace substantially in real time on the basis of position information. The position information is, for example, "Global Positioning System (GPS)" -based, three-dimensional coordinates in the airspace, for example data in GPS Exchange Format (GPX) .The data in GPX format can be geodesics, ie the latitude, longitude and altitude coordinates, Alternatively, the data may also be based on the Galileo, GLON ASS, Beidou / Compass or any other satellite navigation and / or timing system, or on a local or building based navigation system for positioning the aircraft inside and outside buildings (such as by Transmission of transmission signals, optical positioning systems, etc.).

The term "a temporal sequence of positions" essentially corresponds to a given route or a given "track", which may or may also be data in GPX format

Airspeed of the Aircraft 1. It is particularly advantageous to modify the "time sequence of positions" also during runtime of the system, for example by the interaction of a user, or to derive new positions of one or more aircraft 1 from the interaction of the user Kind of

User interaction is communicated to the system. Particularly advantageous is the use of a communication unit for the transmission of the changed positions, or changed, temporal sequences of positions to the aircraft 1.

With the data processing unit 3, it is thus possible, the aircraft 1 with a certain airspeed to a certain position in the airspace or along a to control specific route in the airspace. For this purpose, the rotors of the drive unit 2 are controlled by the data processing unit 3 accordingly. In addition, this indicates

Aircraft 1, for example, a GPS receiver, so as always the current position of the aircraft 1 with the predetermined position or route based on

Position information.

The "activation of a chronological sequence of positions of the aircraft 1 in the airspace" thus denotes, inter alia, the control of a movement or trajectory of the aircraft 1 in the airspace, ie essentially the control of the flight of the aircraft 1 in the airspace.

The position information may be stored in a memory unit 4. The

Data processing unit 3 receives the position information from the storage unit 4 and controls the aircraft 1 in accordance with this position information. In addition, the data processing unit 3 can transmit the current position information to the memory unit 4, where it is stored, for example for checking or as a backup.

In addition, the aircraft 1 according to the first embodiment has a

Communication unit 5 on. The data processing unit 3 can so

Position information also from an external control device, such as a laptop, a smartphone or a ground control unit, receive or send the current position information to this external control device. Here are the

Receive or transmit position information substantially in real time, whereby a smooth communication is ensured, and whereby the position to be controlled by the aircraft 1 in the airspace can be optionally updated at any time. The communication unit 5 of the aircraft 1 can also be designed to communicate with the communication unit 5 of another aircraft 1. This will be discussed later.

The aircraft 1 according to the first embodiment of the invention further includes

Holding means 6 for holding at least one fireworks body and an activating means 11 for activating the at least one fireworks body. The data processing unit 3 is designed to control the activating means 11. If the activating agent 11 is activated by the data processing unit 3, it activates the fireworks body,

For example, by an ignition, and the firecracker is, if it is, for example, a firework rocket or a fireworks to be shot, shot down in a firing direction 7 of the holding means 6. The functional principle can essentially correspond to that of a firearm, an air pressure weapon, or a spring pressure weapon, wherein the holding means 6 would represent a barrel of the respective weapon and the activating means 11, for example a bolt, an air pressure means, a spring, an ignition mechanism, etc. Alternatively, the holding means 6 and / or the activating means 11 can also be controlled by an external control device, for example by a laptop, a smartphone or a floor control unit.

The holding means 6 is fastened to an alignment means 8 which is rotatable at least uniaxially, for instance about an axis of symmetry 9 of the aircraft 1, or of the alignment means 8. The data processing unit 3 is for controlling the alignment of the

Holding means 6 by means of the alignment means 8 based on alignment information

educated. The holding means 6 can be controlled by the data processing unit 3 or by an external control unit via the communication unit 5.

Advantageously, the alignment means 8 is biaxially rotatable, namely about the axis of symmetry 9 of the aircraft 1 and about a pivot axis of the alignment means 8. The pivot axis is advantageously arranged substantially at right angles to the axis of symmetry 9. While the aircraft 1 is in a stable, substantially static position in the air space, the axis of symmetry 9 is substantially perpendicular and thus the pivot axis is aligned horizontally. By way of example, the orientation of the holding means 6 can thereby compensate or intensify a deviating orientation of the aircraft 1.

Alternatively, the alignment of the holding means 6 can also take place exclusively via the alignment of the aircraft 1 in the airspace.

The alignment information may include, for example, an angle and time information, that is, for example, at what angle about the symmetry axis 9 the

Alignment means 8 at what time to be aligned. The alignment information with the position information can be temporal or spatial

be synchronized, whereby the orientation of the holding means 6 can be adapted to the respective current position of the aircraft 1.

The aircraft 1 according to the invention can thus produce an image in the airspace by means of at least one fireworks body, the image being based on the temporal change of the position of the aircraft 1 in the airspace on the basis of

Position information and / or based on the time change of the orientation of the alignment means 8 can be spatially and temporally varied based on the alignment information. The holding means may comprise a plurality of holding means 6, for example 2 to 10 or more than 10. These plurality of holding means 6 may be aligned together or independently by means of the alignment means 8 or by means of a plurality of alignment means 8 and controlled by the data processing unit 3. Thus, for example, a whole fireworks battery, that is to say a plurality of fireworks which are activated as a function of time, can be launched from an aircraft 1.

The data processing unit 3 is designed to control the activating means 11 and / or the alignment means 8 as a function of at least one safety parameter. This means that the data processing unit 3 only releases the activating means 11, that is, activates it positively if a criterion of the at least one safety parameter is fulfilled. Furthermore, the data processing unit 3 can take back the release of the activating means 11, that is, trigger it negatively, if the security parameter additionally enters

Time criterion has, and the criterion of the security parameter before the expiration of the time criterion is suddenly no longer satisfied. Furthermore, the data processing unit 3 can align the alignment means 8 with respect to the criterion of a further security parameter, for example a security corridor defined by spatial coordinates in the direction of which the firing direction 7 of the holding means 6 is to be aligned. This

Security parameter may additionally have a time criterion, for example, as described in more detail above.

FIG. 2 shows by way of example a plurality of unmanned aerial vehicles in a view from above

Aircraft 1 according to the first embodiment shown in FIG. There are two security parameters 12 and 13 defined, each data processing unit 3 for controlling the corresponding activating means 11 and / or the corresponding

Aligning means 8 is formed in dependence of these safety parameters 12 and 13.

The first exemplary safety parameter 12 is defined by spatial coordinates, such as GPS coordinates in latitudes and longitudes, and virtually extends substantially vertically upward, with a maximum flight altitude of the aircraft 1 bordering a three-dimensional space upward. So it is in the

Security parameter 12 around a virtual space in the form of a cube or cuboid. Each data processing unit 3 activates the corresponding activating means 11 only or releases it only if the criterion of the security parameter 12 is met, whereby this criterion consists in the fact that the corresponding aircraft 1 located within the virtual space. Conversely, the activated

Data processing unit 3 does not release the activating means 11 or does not release it if the criterion of the security parameter 12 is not fulfilled, that is, if the corresponding aircraft 1 is not located within the virtual space.

The second exemplary security parameter 13 is defined by spatial coordinates,

For example, GPS coordinates in latitude and longitude, and by

Directional coordinates, for example, also based on GPS coordinates defined and extends along a virtual three-dimensional truncated cone. each

Data processing unit 3 activates the corresponding activating means 11 only or releases it only if the criterion of security parameter 13 is satisfied, this criterion consisting in that the alignment means 8 of FIG

corresponding aircraft 1 is oriented such that the firing direction 7 and the resulting trajectory of the fireworks body within the virtual

three-dimensional truncated cone are located. Conversely, the activated

Data processing unit 3, the corresponding activating means 11 is not, or is not free, if the criterion of the security parameter 13 is not met, so if the firing direction 7 and / or the resulting trajectory of the

Fireworks are not located inside the virtual three-dimensional truncated cone.

The two safety parameters 12 and 13 are parallel and interdependent, which means that they must both be satisfied simultaneously, hence one

Data processing unit 3, the corresponding activating means 11 is activated. Alternatively one could define the safety parameters 12 and 13 of all aircraft 1 dependent on each other, which would mean that both safety parameters 12 and 13 for all

Aircraft 1 would have to be met simultaneously so that a data processing unit 3 activates the corresponding activating means 11.

Alternatively, as already described above, the security parameters 12 and 13 can additionally have a time criterion or other security parameters, for example consisting of time information, can be defined. The different security parameters may be interdependent or independent and / or serial or parallel.

If a plurality of unmanned aerial vehicles 1 according to the invention are combined in one system, for example in the form of a swarm compound, these can be integrated in Formation controlled so as to create images during an imaging phase in the airspace in dependence of / the safety parameters / s 12 and / or 13.

Figure 3 shows such an inventive system 10 of three unmanned

Aircraft 1 according to the first embodiment shown in FIG. The

Position information and the alignment information are formed as imaging information relating to the image.

The system 10 comprises a ground control unit 15, which is for storing, processing, transmitting and / or receiving the position information and / or

Imaging information is formed. This information is provided by the

Ground control unit 15, for example, from a ground communication unit 16, transmitted via the communication units 5 of the aircraft 1 substantially in real time to the corresponding data processing units 3. This allows particularly complex and very large images by means of a large number of

Aircraft 1, for example, 100 and more, are created in the airspace without the aircraft 1 colliding with each other, wherein a part of the aircraft 1 or all aircraft 1 are controlled by the ground control unit 15. Alternatively, however, these aircraft 1 can also act, without prior control of a ground unit, by previously storing the positions and their timings.

The aircraft 1 of the system 10 additionally have a three-dimensional sensor unit 14 which continuously detects the distance to adjacent aircraft 1 in real time in real time and supplies this distance information to the corresponding one

Data processing unit 3 and / or the ground control unit 15 transmitted. The

Data processing unit 3 and / or ground control unit 15 can then / in essentially real time position information about the feedback from the

Update sensor unit 14. The aircraft 1 can thereby be moved, for example, in a swarm compound. Here, it may be sufficient to control only one to five aircraft 1 to a large amount, for example, 100 and more, to

Aircraft 1 to move, since all other aircraft 1 controlled

Follow aircraft 1 on the basis of swarm intelligence. As a result, the necessary amount of transmitted information can be greatly reduced.

FIG. 3 may alternatively represent a section of a system with substantially more aircraft 1, for example 100 or more aircraft 1. As a result, with the advantageous use of fireworks, complex and particularly large ones may be created Illustrations are created by means of a large number of aircraft 1 in the airspace.

Alternatively, at least one aircraft 1 instead of the holding means 6 a

Imaging means, in particular a LASER means, an LED means or a display means, wherein the activating means 11 for activating the imaging means and the data processing unit 3 for controlling the activating means 11 and the imaging means based on imaging information and / or for aligning the imaging means are formed by means of the alignment means 8 based on alignment information.

As a result, under the advantageous use of fireworks and

Imaging means particularly complex images are created by means of a large number of aircraft 1 in the airspace.

With respect to the holding means 6 and the imaging means are all conceivable

Combinations, in particular on the basis of the examples described above, possible.

A method according to the invention for generating an image in airspace during a mapping phase by means of the system 10 is described below:

For example, the system 10 is designed so that all the information is stored in a memory of the ground control unit 15 and, for example, the

Imaging information, position information, alignment information,

Time information, distance information and the safety parameters continuously retrieved by a control software and transmitted via the ground communication unit 16 and the communication units 5 to the data processing units 3 of the aircraft 1. This means that during the entire imaging phase, the method steps A) and B) and the optional method steps C) and D) are performed successively and / or simultaneously with respect to one or each aircraft 1.

In a method step A) are essentially in real time

Map information to the data processing units 3 of the aircraft 1 transmitted. In a method step B), the data processing units 3 control the aircraft 1 within the airspace essentially in real time on the basis of FIG

Map information to the appropriate locations. During or after method step (s) B), at least one fireworks body is activated as a function of at least one safety parameter. In an optional method step C), the ground communication unit 15 transmits mapping information to the data processing unit 3 of another of the

Aircraft having imaging means. The imaging means may be formed by a display or other comparable means. In a further optional method step D), the data processing unit 3 controls the at least one further aircraft 1 with the imaging means within the airspace on the basis of

Position information and activated during or after the method step (s) D) the at least one imaging means of this aircraft. 1

The method steps A) and B) and optionally the method steps C) and D) can be carried out essentially in real time in any order sequentially and / or simultaneously for all aircraft 1 or only for parts of the aircraft 1. Thus, three-dimensional and dynamic images in the airspace can be provided.

It may be mentioned that an aircraft or system according to the invention can be used for the controlled and automated safe breaking off of snow or rock / rock avalanches.

The term "unmanned aerial vehicle" is to be interpreted very broadly in the context of this invention and could include, for example, hot air balloons, zeppelins, model airplanes or model helicopters.

The term "firecracker" is to be interpreted in the context of this invention is very broad and could for example be a burning ball or other object with a burning or explosive substance.

Furthermore, the term "firecracker" in the context of this invention, in particular very broad interpretation, since for safety reasons, which correspond to the spirit of this invention, a "fireworks" in the context of this invention can also represent an object that has no burning or explosive substances, for example a luminous or colored object, in particular based on fluorescent, phosphorescent or otherwise chemically or electrically activated luminous and / or colored materials and / or effects. According to a further embodiment of the invention, an aircraft according to the invention has no alignment means for aligning the fireworks body. The alignment of the fireworks takes place here by the respectively flown by the aircraft flight maneuver. The horizontal orientation of the fireworks can be done by simply rotating the aircraft about its own axis, which is particularly easy with UAVs, where the vertical orientation of the fireworks body could be preset by the retaining means. In addition, the vertical orientation of the fireworks for the correct launch position could be due to the currently flown

Flight maneuvers, that is done by briefly lowering or lifting a side of the UAVs in flight.

According to a further embodiment, the recoil of the fireworks body can be taken into account both for the desired trajectory following the launch and for a safe firing of the fireworks body. Thus, the recoil of the fireworks body when shooting to a twist or tilt the

Lead the launching direction. It is particularly advantageous in this case, if this possible change in the firing direction in terms of safety is taken into account.
