Definitions
- the invention relates to a paraglider control for controlling a paraglider drive, in particular an electric ascent aid, for a paraglider and a method for controlling the paraglider drive.
- Electrical ascent aids for paragliders enable a pilot with a paraglider to start on foot or with a roll start even on level terrain and then stay in the air for a longer period of time in flight without dynamic updrafts or thermals, e.g. B. to find connection to a thermal or an updraft band.
- electric climbing aids have, for example, an electric drive or a motor with a rotor, power electronics for generating the rotary electric field, rechargeable batteries, a microprocessor and a handle for thrust control.
- the pilot mainly needs both hands to control the paraglider during take-off and, if necessary, also during flight, in order to be able to carry out two-handed control impulses.
- the pilot must also control the electric ascent aid, more precisely the thrust and/or alignment of the motor or rotor, which, for safety reasons, is usually located at a distance behind the pilot in the direction of flight, in particular outside the pilot's arm's reach, or placed in a protective cage.
- the paraglider control mentioned at the outset is used for—preferably acoustically—controlling a paraglider drive for a paraglider.
- Paraglider drives within the meaning of the invention include climbing aids and other drives such. B. motors for UL motor screens, or alternative drives z. B. nozzle-based.
- the paraglider control serves to control an ascent aid.
- the terms "climbing aid control” and “paraglider control” as well as “climbing aid” and “paraglider drive” are essentially used synonymously.
- the ascent support controller includes a UI port interface for sending and/or receiving user commands, which include one or more voice signals. Optionally, it also has a flight data interface for receiving flight data.
- the ascent aid control includes an evaluation unit for evaluating received user commands and optionally flight data.
- a user signal is output via the UI connection interface and/or a control signal is output via a control interface.
- User commands are input and/or output using the UI connection interface by means of the voice signal.
- a paraglider also known as a paraglider or paraglider, is foot-launched air sports equipment for paragliding or paragliding. It includes a canopy, lines and risers.
- the canopy or the wing is usually approximately elliptical and made of nylon fabric. It usually includes an upper and lower surface and is divided into numerous chambers that extend in the direction of flight. It has two canopy ends, i.e. two wing tips, which form the lateral end of the wing.
- Gallery lines usually run down from the underside of the sail in several levels, which are brought together to form main lines. The main lines are in turn hooked into line locks and are connected to the respective left and right webbing.
- a harness for the pilot is required for paragliding.
- the paraglider is connected to the pilot's harness with carabiners via the straps, also known as risers. 3
- the load which is carried by the paraglider, is attached to the risers by means of carabiners.
- the load therefore refers to the total weight hanging from the paraglider.
- the load includes e.g. B. also a climbing aid, d. H. engine and linkage.
- the motor can be arranged behind the pilot in the direction of flight, for example by means of the linkage or by means of push rods.
- the UI connection interface or "user interface” connection interface is used to send and/or receive user commands, i. H. for example inputs by a user for the ascent aid control or useful and/or warning outputs or instructions of the ascent aid control for the user.
- user commands can also come from users other than the pilot, for example from a co-pilot in a tandem flight.
- user commands can also be sent by a user monitoring the flight, e.g. B. an air traffic controller or flight instructor, received or sent.
- Such user commands include, inter alia, a voice signal.
- Spoken language or the underlying speech signal can mean, for example, an automatic speech output and/or an input of speech modules or words.
- the speech signal can also be present and transmitted in analog or digital form.
- the evaluation unit evaluates received user commands.
- the evaluation unit can be embodied, for example, on a microprocessor.
- the evaluation unit can preferably also evaluate this and z. B. summarize to a flight condition.
- the flight data include different measurement data, which are recorded by means of appropriate sensors or a sensor arrangement.
- sensors can, for. B. be a number of distance sensors, in particular ultrasonic sensors, acceleration sensors, gyroscopes, magnetometers, barometers and / or GPS sensors.
- flight data can also include data from a LIDAR sensor.
- the flight data include at least the current sensor data.
- previous sensor data are preferably also included as a flight history in order to include a development of the flight situation or the flight status. 4
- the sensors can therefore be combined in sensor units, for example, which are arranged in particular at the ends of the shield cap and/or in the area of the load, e.g. one or more IMU (Inertial Measurement Unit).
- IMU Inertial Measurement Unit
- the sensors can be connected to the flight data interface individually or as such a sensor arrangement.
- the flight data recorded by the sensors can optionally be received via a flight data interface.
- a user signal is then output via the UI connection interface.
- Outputting the user signal can e.g. B. acoustically or visually.
- Such a user signal can, in the simplest case, e.g. B. be a warning or advisory sound signal or light signal or flashing signal.
- a user signal can be of any complexity.
- individual words or sentences can be output, which include, for example, a number of flight dates lined up in a row.
- it can essentially contain any kind of flight status information, the flight status of the paraglider or instructions for the user.
- Flight status information can be, for example, the general flight status parameter, the stability parameter for the canopy, the categorization of the current flight maneuver or the dangerous situation, or the like.
- a control interface outputs a control signal from the ascent aid, e.g. B. if the user command contains a control signal.
- control data or control signals contain, for example, control information; H. e.g. B. Values and parameters for thrust, the alignment of the drive or motor of the climbing aid.
- a control unit for example, is connected to the drive of the climbing aid in such a way that it can transmit control signals to the drive and execute them using it.
- control instructions or control signals or status queries or user signals - takes place according to the invention using the UI connection interface by means of the above-mentioned voice signal. 5
- the device according to the invention described above means that a user can control the electrical climbing aid by voice.
- the pilot advantageously has access to the ascent aid control of the ascent aid at any time, independently of other current activities to be carried out with his limbs for the actual control of the paraglider, by issuing precise or concise commands by voice.
- a climbing aid control for controlling an electrical climbing aid for a paraglider
- user commands or user signals can be input and/or output using a UI connection interface by means of a voice signal.
- a method for controlling an electric ascent aid for a paraglider with a UI connection interface preferably for input and/or output means, a control unit and an evaluation unit, comprises at least the following steps:
- the UI connection interface sends and/or receives user commands which include at least one voice signal.
- the evaluation unit evaluates correspondingly received user commands.
- a user signal is output via the UI connection interface and/or a control signal is output via the control interface to the climbing aid.
- user commands are input and/or output using the UI connection interface by means of the voice signal.
- a flight data interface of the ascent aid control receives flight data, at least when flight data is provided or generated.
- the evaluation unit evaluates the flight data, preferably in addition to the received user commands, and particularly preferably receives the flight data via the flight data interface.
- the user signal and/or the control signal are determined using the result of the evaluation of the flight data.
- a climbing aid control in particular according to the invention, which has a UI connection interface, a flight data interface and an evaluation unit can be designed in such a way that the evaluation unit includes an analysis unit for analyzing a flight status.
- the analysis unit which is preferably pre-trained by means of a machine learning process, can analyze the data that the evaluation unit receives and evaluates in such a way that it a current flight condition, and particularly preferably given to a prediction of a future flight condition, if necessary.
- a user signal ie in particular the current flight status or the prediction of a future flight status, and/or a control signal based on the flight status can then be sent to the ascent aid via the UI connection interface.
- the "flight condition" can usually be determined from the interaction of a large number of input parameters which, according to the invention, include the first distance and/or at least one second distance.
- Other parameters are explained in detail later, they include, for example - for one or more axes - a positi on, a speed, an acceleration, an angular position, a speed Winkelge and / or an angular acceleration of the paraglider or individual com ponents thereof and z.
- the flight status is determined by means of the evaluation unit.
- the evaluation unit combines, for example, the previously recorded values of individual input parameters into output parameters that are relevant for the pilot and characteristic of the flight condition and outputs their values.
- output parameters are a general flight status parameter, which combines all input parameters into a value that is characteristic of the current and/or future flight situation, or a stability parameter for the canopy, which indicates whether the canopy is in a stable condition or, e.g. B. is about to collapse.
- the flight status can also be characterized by a vector of individual output parameters.
- an abstract parameter or vector of parameters can also be determined as the flight condition, which, for example, contains a camera 7 categorization of the flight condition into conventional manoeuvres, aerobatic maneuvers and/or hazardous situations.
- Conventional flight maneuvers are e.g. E.g.: Control maneuvers such as pitching, rolling, “fast figure eight", “circling in the updraft band", descent aids such as a steep spiral, "big ears” or “B-stall”.
- Aerobatic maneuvers are e.g. E.g.: "Helicopter”, “SAT” or "(infinity) tumbling”.
- Dangerous situations are e.g. B.: a complete or one-sided stall ("stall"), an accelerated or unaccelerated lateral deformation (“collapse”), a front deformation ("front stall") as well as a permanent deformation ("cravat”).
- stall complete or one-sided stall
- stall an accelerated or unaccelerated lateral deformation
- front deformation front stall
- cravat permanent deformation
- the flight status is thus described by output parameters which, compared to the input parameters, enable the actual flight situation to be recorded and evaluated more quickly and easily.
- the assessment can be made by the pilot, by a flight instructor or z. B. also computer-based.
- the flight data include at least the current sensor data.
- previous sensor data are preferably also included as a flight history in order to include a development of the flight situation or the flight status.
- the flight data include z. B. completely or partially measured values for the input parameters mentioned above.
- the flight status system described here for predicting a future flight status of the paraglider represents an independent idea on its own. However, special synergetic effects result when it is combined with the flight status system described above. In particular, the flight status, as described above, can be determined, included in the flight data and included in the prediction.
- the analysis unit preferably includes a trained AI-based method.
- AI-based method denotes a machine method that mimics cognitive functions related to the human mind.
- the term includes B. simple machine learning and deep machine learning.
- “Simple” or “traditional” machine learning methods include e.g. B. logistic regression, support vector machine (SVM), random forest or similar.
- the trained AI-based method is able to adapt to new circumstances and to recognize and extrapolate patterns through training on the basis of training data.
- supervised training, semi-supervised training, unsupervised training, reinforcement learning, and/or active learning may be used.
- the parameters 8 ter of the trained Kl-based method can be iteratively adapted through several training steps.
- the trained AI-based method can particularly preferably be embodied as a deep machine learning method, very particularly preferably as a neural network.
- the neural network may include a deep neural network, a foldable neural network, or a foldable deep neural network.
- the neural network has a known basic architecture. However, its inner structure is individually shaped by the training. The training thus defines the inner "structure” of the neural network and distinguishes it from other trained neural networks (also with the same basic architecture).
- the weights or parameters within its structure are automatically adjusted so that they resemble the training data.
- Known optimization approaches e.g. B. a gradient descent algorithm or an Adam algorithm in combination with e.g. B. the cross-entropy loss function can be used.
- the input data (input vector) for the neural network includes measured values from the sensors mentioned above. Depending on the application or specific configuration of the neural network, either measurement data from all sensors or only the measurement data from some of the sensors can be used. The measured values can only be included at one point in time, but a time profile of the measured values from a defined time interval can also be combined as an input vector.
- the training data includes the input data or input vectors and assigned annotations by experienced pilots.
- the pilots can, for example, create annotations for their own flight or, for example, annotate the flight status accordingly using additionally recorded video sequences.
- the flight condition with regard to output parameters such as a general flight condition parameter (general assessment of the flight situation under safety aspects) z. B. using a freely selectable scale, stability parameters for the canopy z. B. using a freely selectable scale, a categorization of the flight condition in defi ned conventional maneuvers, aerobatic maneuvers and / or defined dangerous situations or the like are annotated.
- the measured values of the sensors for the training data in relation to the conventional maneuvers can also be recorded during normal paragliding, the measured values of the sensors for the training data in relation to the dangerous situations in a safe environment (e.g. over water at present water rescue) by experienced pilots by means of deliberately initiated dangerous situations.
- a safe environment e.g. over water at present water rescue
- the weights/parameters of the network are adjusted for the specific task and can e.g. B. Evaluate flight situations with regard to safety and/or the stability of the canopy and/or recognize the current maneuvers or dangerous situations.
- a future flight state can be predicted, preferably using a trained AI-based method, particularly preferably using a neural network.
- Typical countermeasures such as e.g. B. weight shift, countersteering, braking or the like, which help the pilot to avoid the dangerous situation and / or improve the flight condition.
- the flight status system preferably includes acoustic and/or optical output means for outputting the flight status and/or an instruction based on the flight status and/or a prediction.
- the pilot can be informed about a critical flight condition directly with the help of warnings by the ascent aid control, so that he z. B. can normalize the flight condition early by appropriate korri governing flight maneuvers.
- the pilot can receive user signals from the ascent aid control with instructions for improving the current flight situation.
- control signals can also be output directly by means of the control unit, so that, among other things, the flight status can be improved with the aid of the drive of the ascent aid. 10
- the ascent aid control for the pilot can advantageously also trigger the rescue parachute directly and at the same time possibly separate the pilot from the other components of the ascent aid.
- an ascent aid control is therefore also advantageous independently of the ascent aid control described above and represents an independent idea.
- special synergetic effects result from a combination of the two ideas.
- an electric ascent aid can be controlled particularly safely by voice, taking into account the current flight status.
- the current flight status can therefore be taken into account in real-time control.
- a paraglider according to the invention comprises at least one electrically operated climbing aid and a climbing aid control according to the invention.
- the ascent aid can have at least one electric drive or electric motor.
- B. an electric backpack motor with or without a protective cage, in particular a brushless three-phase synchronous electric motor can be connected, for example, with at least egg nem rotor or a number of rotor blades.
- backpack engines - mostly with a two-stroke engine with a fuel tank and a propeller - can be used.
- the ascent aid control according to the invention can advantageously be retrofitted to existing ascent aids. However, it is also possible to equip new climbing aids to be manufactured with a climbing aid according to the invention during production.
- the essential components of the ascent aid control according to the invention can for the most part be in the form of software components.
- these components can also be partially implemented in the form of software-supported hardware, for example FPGAs or the like, particularly when particularly fast calculations are involved.
- the required interfaces for example if it is only a matter of taking over data from other software components, can be designed as software interfaces. However, they can also be in the form of hardware interfaces that are controlled by suitable software. 11
- a largely software-based implementation has the advantage that climbing aids that have already been used can easily be retrofitted with a software update in order to work in the manner according to the invention.
- the task is also solved by a corresponding computer program product with a computer program, which can be loaded directly into a memory device of a lift control of a lift, with program sections to carry out all the steps of the method according to the invention when the program is executed in the lift control .
- Such a computer program product can terprogramm next to the Compu, if necessary, additional components such. e.g. documentation and/or additional components, including hardware components such as hardware keys (dongles etc.) for using the software.
- a computer-readable medium for example a memory stick, a hard disk or another transportable or permanently installed data medium, on which the program sections that can be read and executed by a computer unit of the ascent control can be used for transport to the ascent control and/or for storage on or in the ascent control of the computer program are stored.
- the computer unit can, for example, have one or more working microprocessors or the like.
- User commands for or from the ascent aid control are preferably input and output using the UI connection interface by means of the voice signal.
- the ascent aid control can be controlled bidirectionally by voice in this way means that a pilot can control the ascent aid in normal operation entirely without hands, so that his hands are available in particular for operating or controlling the paraglider.
- Using the voice output can 12 visual displays are avoided, allowing the pilot to orient his field of vision independently of any displays and reducing visibility with fewer displays.
- optical output means can of course preferably also be used, such as e.g. B. a wrist display, a smartwatch or a smartphone with a corresponding holder; AR ads (augmented reality) that provide instructions or information, e.g. B. in glasses or in a helmet visor as an overlay in the field of view, or the like.
- AR ads augmented reality
- speech recognition can also be carried out, for example, in a specially designated area within the evaluation unit that is “spatially” separate from the rest of the evaluation, i. H. certain processes can be outsourced from the evaluation unit and/or run upstream of the evaluation of the evaluation unit.
- the evaluation unit preferably has voice recognition for recognizing and evaluating acoustic, e.g. B. spoken, user commands.
- speech recognition means automatic or machine recognition of spoken language. Speech recognition basically describes the ability of a machine or a program to identify spoken words and sentences and convert them into a machine-readable format.
- speech recognition that only has a certain predefined vocabulary is sufficient as speech recognition software. However, she then recognizes this predefined vocabulary very reliably, even if it may be pronounced more “naturally”, especially less clearly.
- the speech recognition is preferably a speaker-independent speech recognition in which a user is immediately recognized by the speech recognition without a previous training phase.
- the input is first recorded with speech recognition software and/or hardware.
- the speech signal or the input can then be decrypted by means of speech recognition and transmitted to the evaluation unit for evaluation.
- this can 13
- the voice signal can then be sent back to the evaluation unit for evaluation or automatically transmitted.
- Speech recognition is preferably carried out using speech recognition libraries such as B. Snips, Mozilla open source STT (Speech-to-Text), S.E.P.I.A. or similar.
- speech recognition libraries such as B. Snips, Mozilla open source STT (Speech-to-Text), S.E.P.I.A. or similar.
- Aids are preferably used to detect the voice signal in order to suppress the air noise that is unavoidable during the take-off phase and in flight, or at least to reduce it to such an extent that the transmitted useful signal can be reliably distinguished from the noise signal by the evaluation unit.
- the aids are preferably damping elements and/or also other common wind shields of a general kind.
- a microphone-like detection device is also preferably arranged in the pilot's mouth. The air flow caused by the environment has virtually no disruptive influence on this.
- the input or user input, in particular voice input, of a user command preferably takes place with an activation word, a parameter and optionally a parameter value.
- activation word is here a number of predefined words, i. H. at least one word to understand. It precedes any voice user command to trigger voice recognition activation of the climbing aid control. After triggering, the input is then decrypted or converted into a machine-readable format.
- the activation words can be predefined in such a way that they are either fixed, can be selected from a list of permanently predefined activation words, or can be freely predefined by the user beforehand. With at least one activation word, specific components of the ascent aid or ascent aid control can be activated particularly quickly without the actual voice recognition having to process and/or interpret the activation word.
- a "parameter” can simply mean a variable defined for the control of the ascent aid that has a specific range of values.
- a specific parameter value from the value range for the associated parameter a predefined state of the climbing aid can be controlled or reached exactly and unambiguously turn 14 For example, a specific percentage of a maximum thrust of the drive can be set or regulated in this way.
- Such an activation word, a parameter and a corresponding parameter value from the value range of the parameter can be generated jointly by means of the control unit with sufficient control data or control signals.
- the activation word in the user command can preferably be detected or recognized by means of an upstream activation word detector integrated in the evaluation unit for activating the speech recognition.
- the activation word detector is used to identify an activation word for speech recognition. Immediately after recognizing such a word, the activation word detector can activate the speech recognition, which in turn recognizes the command and transmits it to the evaluation unit in a machine-readable format.
- the computing power required to recognize the activation word is provided locally and in a resource-saving manner by the activation word detector and the evaluation unit is only woken up from a "standby mode" when an activation word is detected. This means that speech recognition does not have to be permanently active or switched on, which in turn saves resources.
- a standalone external activation word detector can also be used.
- a wake-up word detector included in a mobile phone or smartphone could be used in a voice recognition app.
- the voice recognition of a smartphone or voice recognition with an integrated activation word detector could preferably also be used on a smartphone in order to further reduce the computing power of the evaluation unit. Consequently, the evaluation unit could obtain its information for controlling the ascent aid simply wirelessly or via a cable connection via the mobile terminal device if the pilot uses it as an input device.
- the ascent aid control is not limited to a purely acoustic "voice control". If this proves advantageous, certain components can also be controlled manually in addition to the acoustic control. This can e.g. B. by rotary or sliders, joysticks, or switches z. B. for an emergency shutdown of the engine or for an emergency release of the rescue parachute. Manual control with a standard smartphone would also be possible, for example. 15
- the electrical ascent aid for a paraglider with an ascent aid control is preferably designed in such a way that at least the pilot can manually or mechanically separate and save himself from the electrical ascent aid in the event of danger, independently of the ascent aid control.
- a lock and/or a knot can be loosened or the like.
- an additional rescue device or emergency parachute for the other components of the ascent aid can also be deployed accordingly, so that the ascent aid can also be brought to the ground without causing any damage.
- the ascent aid can hang below the pilot on a rope or a similar safety device.
- an additional user command can also be provided, by means of which the pilot can electromechanically decouple himself from the ascent aid.
- the ascent aid control preferably includes a rescuer interface for detecting a user command to deploy the rescue parachute.
- the release of the rescue parachute via the rescuer interface preferably also includes the decoupling of the pilot from the ascent aid, in particular the drive, rotor and a rechargeable battery or battery. This allows the pilot advantageously in an emergency, z. B. in the event of an engine and/or battery fire, be separated from the burning components as simultaneously or at the same moment as possible and land safely with the rescue parachute.
- voice control can be used to separate the damaged components from the pilot and trigger the pilot's rescue parachute.
- the ascent aid control can preferably include acoustic and/or visual output means and/or acoustic and/or manual input means.
- the output means can include a number of displays or electronic display units and/or loudspeakers.
- the input means can be z. These could be, for example, microphones and/or (touch) displays with face recognition or gesture control.
- the ascent aid control is preferably connected to the drive or motor of the ascent aid, which is preferably connected to at least one rotor, by means of the control interface.
- the drive can particularly preferably by voice, z. B. by means of a 16 evaluated and processed user command, which has been converted into a control signal for the Steuerein unit can be controlled.
- the ascent aid control can preferably be designed in such a way that it can be used to control or regulate the thrust and/or alignment of the drive and/or electronic flight instruments of the electric ascent aid.
- the boost can be given as a percentage of the parameter value, e.g. B. as a spoken user command.
- manual control can also be implemented.
- the electronic, in particular digital flight instruments can be, for example, mobile terminals, other displays, AR displays or the like, which can also visually display or display information on the flight altitude or on climb or fall values or parameters relating to the flight status.
- the displays of the flight instruments can preferably be adjusted using voice commands, e.g. B. Depending on the flight situation, you can choose between predefined graphic layouts.
- the orientation of the drive is z. B. realized by means of a pivoting mechanism which is operated by an electric motor.
- the thrust motor can preferably be switched to a mode for active position control by means of a control signal.
- the swivel mechanism ensures, for example, that the axis of rotation of the rotor is aligned with the direction of flight.
- the interfaces mentioned above are preferably designed as cableless or wireless interfaces, such as Bluetooth, WLAN, ZigBee, NFC, Wibree or WiMAX in the radio frequency range and IrDA and optical radio link (FSO) in the infrared or optical frequency range.
- the interfaces can also be fully or partially wired. Transmission can also take place here via an analog or digital signal.

- the ascent aid control 40 is included in the central unit 30 which is arranged in the area of the load 53 . Also shown are two peripheral screen cap end sensor units S2, S3, which are located in the area of the screen cap ends 52 of the 19
- a central sensor unit S1 is integrated into the central unit 30 in this exemplary embodiment.
- the central sensor unit S1 and the two shield cap end sensor units S2, S3 form a sensor arrangement S1, S2, S3 with the first and second distances already described with reference to FIG.
- the two canopy end sensor units S2, S3 are each connected to the central unit 30 and thus to the ascent aid control 40 by means of sensor interfaces 28 or flight data interfaces 28 . They each have a distance sensor 21 , an acceleration sensor 22 and a gyroscope 23 .
- the circumcision sensor 22 or the gyroscope 23 is the acceleration in the direction of all axes and can be designed as a combined IMU, for example.
- the canopy end sensor units S2, S3 can also have other sensors, such as a magnetometer 24 or a dynamic pressure sensor, if required.
- the central sensor unit S1 also includes a barometer 25, a GPS sensor 26 and a LIDAR sensor 27, the measuring range of which is aligned with the rotor 59, compared to the sensor units S2, S3 at the end of the canopy. It can thus be determined with the LIDAR sensor 27 whether an object penetrates into the safety area of the rotor 59 .
- the gyroscopic values of the paraglider 50 are determined to determine the rate of rotation about the roll, pitch and yaw axes and to detect deformation of the airfoil.
- the acceleration values of the paraglider 50 are determined in order to be able to derive the movement of the glider or individual parts, to determine the horizontal alignment (vector of earth gravity) and for the absolute long-term correction of the relative gyroscope.
- the long-term correction describes the compensation of the long-term drift of the gyroscopes. Since a gyroscope only records relative angular velocities, the absolute starting point must be redetermined at defined intervals. This is done for roll and pitch 20
- the acceleration values of the pilot or of the load 53 are determined in order to determine the "synchronization" between paraglider and pilot, since movement deviations can occur due to the system (pendulum) and to determine the movement vector during a take-off phase.
- the gyroscopic data of the pilot or the load 53 are determined to determine the thrust vector and to detect disturbances during the takeoff phase (e.g. the pilot falls during takeoff).
- the magnetometric data of the paraglider and the pilot are used to determine the difference in the orientation around the z-axis, since the pilot is in the final phase when using a so-called "reverse launch” (glide is inflated backwards, but still has to be launched forwards). must turn 180° in relation to the paraglider before take-off. It is important to clearly determine the point in time of turning and the start of the acceleration phase.
- the magnetometric data from the paraglider are also used for long-term correction of the relative gyroscope.
- the relative distance measurement between the wing end points and the pilot using ultrasound is also used as a long-term correction of the "integrated acceleration" or to determine speed and position and in addition to determining line stretch.
- the air pressure is measured in order to determine the internal dynamic pressure of the paraglider and to record thermals (sinking or rising air masses).
- the global positioning system e.g. GPS, Galileo, etc.
- GPS global positioning system
- Galileo Galileo, etc.
- All of these calculations can be performed before the corresponding results are sent to the neural network as input data.
- the neural network can also be trained in such a way that it immediately evaluates the measured sensor data. 21
- the sensor arrangement S1, S2, S3 can, for example, also include one or more additional sensor units, such as e.g. B. the canopy center sensor unit S4 (see Figure 1), which serves as an additional (zero) reference for the long-term correction of the relative gyroscope and, if necessary, also includes a dynamic pressure sensor in order to enable holistic Chess recording of the dynamic pressure distribution in the canopy .
- additional sensor units such as e.g. B. the canopy center sensor unit S4 (see Figure 1), which serves as an additional (zero) reference for the long-term correction of the relative gyroscope and, if necessary, also includes a dynamic pressure sensor in order to enable holistic Chess recording of the dynamic pressure distribution in the canopy .
- the central unit 30 includes the ascent aid control 40, which is connected to the sensor interface 28 and the central sensor unit S1 via a central bus 29 and receives data sent via it.
- the central bus 29 thus also acts as an internal flight data interface.
- the ascent aids control 40 has an evaluation unit 37, a control unit 35 and a flight recorder 31 on.
- the flight recorder 31 is a writable and readable memory. It can be designed as an SD card or micro SD card, for example. Alternatively, it can also be in the form of a permanently installed memory that can be read out via an interface.
- the flight data that is to say the measurement data from all sensors and determined flight conditions, are stored on the flight recorder 31 .
- the flight states are determined in the evaluation unit 37 by means of an analysis unit 38 using a neural network.
- the measurement data from the sensors and possibly a time profile of this measurement data serve as the input vector.
- the neural network of the analysis unit 38 has been trained and is therefore designed for the specific task, by analyzing the flight data, i.e. the measurement data from the sensors, the flight situations with regard to safety and/or the canopy with regard to to evaluate their stability and/or to recognize the current maneuvers and/or dangerous situations.
- the analysis unit 38 can predict dangerous situations based on the patterns that precede them in the flight data, as also described above.
- the ascent aid control 40 is also connected via a UI connection interface 32 to acoustic output means 33 and optical output means 34 as well as a microphone 33' as an acoustic input means for detecting user commands NB.
- the acoustic output means 33 can include headphones and/or a loudspeaker, for example.
- the optical output means 34 can e.g. B. as a wrist 22 display, be designed on a smartwatch or a smartphone with the appropriate holder.
- the optical output means AR displays include the instructions or information z. B. in glasses or in a helmet visor as an overlay in the field of view.
- a user command NB captured by the microphone 33' is routed via the central bus 29 to the evaluation unit 37 and analyzed there.
- an activation word detector 11 is first used to check whether the user command NB begins with a predefined activation word AW.
- the user command NB is further evaluated by a downstream voice recognition system 10 and it is determined whether valid control signals can be determined therefrom. In the other case (no valid activation word AW), the user command NB is discarded.
- the control unit 35 can, for example, control the motor 58 via a control interface 36 .
- the thrust can be regulated by means of a user command NB or additional thrust can be provided if the canopy 51 threatens to collapse.
- an emergency shutdown of the motor 58 can take place if foreign bodies penetrate into the safety area of the rotor 59 .
- the control unit 35 can, for example, also control the trigger for the rescue parachute 61 so that it deploys automatically in an emergency situation or triggered by a user command NB.
- the central sensor unit S1 or the ascent aid control 40 can be designed as a separate component.
- the ascent aid control 40 and/or the evaluation unit 37 can, as already stated above, essentially be implemented using software, so that with suitable interfaces (e.g. W-LAN, radio connection, etc.) it can also be configured on a smartphone, for example, or arranged in a ground station can.
- suitable interfaces e.g. W-LAN, radio connection, etc.
- the interfaces 28, 32, 36, 36' shown and also the connection to the central sensor unit S1 can be either wired or wireless (eg W-LAN, Bluetooth, Zigbee, radio connection, etc.).
- FIG. 4 shows a flowchart of an exemplary embodiment of a method according to the invention for determining a flight condition of a paraglider 50.
- a first step I measurement data from the sensors are recorded by means of the sensor arrangement S1, S2, S3 and a first distance d1 between the canopy ends 52 and the two two ten Distances d2, d3 between a canopy end 52 and the load 53 are determined.
- a flight state is determined in the analysis unit 38 of the evaluation unit 37 by means of a neural network using the first distance d1 and/or the second distances d2, d3. This means that the flight situation is evaluated with regard to safety and/or the canopy is evaluated with regard to its stability and/or the current maneuvers and/or dangerous situations are recognized.
- the analysis unit 38 uses the neural network to make a prediction about possible dangerous situations based on the patterns preceding them in the flight data.
- a user command NB is recorded as a voice signal S using the microphone 33' and forwarded to the evaluation unit 37 via the UI connection interface 32.
- the activation word detector 11 in the evaluation unit 37 first checks whether the user command NB begins with a predefined activation word AW—if not, the user command NB is discarded. Otherwise, user command NB is further evaluated by the downstream voice recognition 10 in step VI and z. B. assigned to a corresponding variable or variables. In doing so, e.g. B. determined whether the user command NB contains a valid parameter P and a valid para meter value PW.
- the parameter P and the parameter value PW are evaluated together with the flight condition FZ and/or the prediction FZ' in a further step VII by a simple prioritization logic.
- the user commands NB normally enjoy z.
- engine control takes precedence.
- the parameter P in question is thus set to the associated parameter value PW in accordance with the user command, e.g. B. the thrust of the engine is regulated to 50%. But if e.g. B. a critical flight situation occurs, the engine z. B. only on the basis of the evaluated flight condition FZ or the prediction FZ 'switched off or the rescuer triggered. In this case, the flight status FZ or the prediction FZ' has priority. 24
- the flight condition and/or the prediction can be output as a user signal N by means of the acoustic output means 33 and/or the optical output means 34 in step VIII.
- an instruction A can be issued via the acoustic output means 33 and/or optical output means 34, with the help of which the current flight status FZ can be improved or the current dangerous situation can be ended.
- the motor 58 or the trigger for the rescue parachute 61 can be activated by means of the control device.
