Description

OBJECT OF THE INVENTION

An object of the present invention, as established in the title of the invention, is a haptic augmented reality device for facilitating the actions on a flying boom from a flight refueler or tanker aircraft to an aircraft to refuel.

An object of the invention is also a device for the control of the haptic augmented reality device.

Another object of the invention is the system wherein the control device of the haptic augmented reality device is integrated.

When in-flight refueling tasks are performed from a flight refueler to a recipient plane a boom is used which emerges from the flight refueler and is provided at its end with what is known in the sector as a “boom”, whilst the specialists in charge of handling the boom are known as “boomers” or boom operators, using joysticks for this.

The haptic augmented reality device, and the control device it is integrated in, is characterized in that it allows performing the actions to control the boom with a single hand, without the need for any training in what the manoeuvres refer to. The system also provides information and assistance concerning how the operation is being performed, indicating to the operator if an operation is recommendable or not.

Therefore, the present invention is included within the scope of haptic control systems on the one hand, and operation control systems of in-flight refueling on the other.

BACKGROUND OF THE INVENTION

At present, when in-flight refueling tasks are performed with a boom, the specialists in charge of handling them are known as “boomers” or operators, using joysticks to control that refueling element.

Said control elements allow the vertical or horizontal movement of said boom similarly to that used in video games to fly in a plane or drive a car. Likewise, the extraction and retraction of the boom or extending part of the boom, is performed with another joystick that is usually handled with the left hand. Although these devices used are fairly intuitive, prior training is required so that the operator associates his/her movements with those of the boom to control. As has been indicated, both hands are necessary to handle the refueling boom and they do not usually give the user any type of feedback concerning how the operation is being performed, nor regarding the actions that are or are not permitted.

The joysticks of the state of the art used for handling the booms are complex to handle, and both hands must be used, in addition to requiring prior training, lacking any means of indicating whether the movement to be performed is permitted or not.

Therefore, an object of the present invention is to develop a device that facilitates the control and handling of the booms used in in-flight refueling, which can be used with a single hand and which has means of indicating whether the movements intended to be performed are permitted or not, developing a device such as that described below, and which is essentially set down in claim 1.

DESCRIPTION OF THE INVENTION

The object of the present invention is a haptic augmented reality device for facilitating the actions to control a boom in full flight, allowing the boom to be controlled with a single hand, without the need for any training in what the manoeuvres refer to. In addition, the system not only provides information concerning how the operation is being performed, but also provides assistance, indicating to the boomer when a particular movement is completely prohibited (making the movement impossible) or is not recommendable (making it necessary to apply more force to perform the movement).

Thanks to the device it allows completely or partially automating the in-flight refueling process. This device and the associated control mechanism radically improve the current situation, allowing the user to handle the boom with a single hand.

An object of the present invention is also the control device wherein the augmented reality device is integrated, which allows facilitating the actions on a boom.

The haptic device and the control device are integrated in a system which helps control and refueling in flight.

The haptic device comprises:

    • a first double set of motors, which allow a horizontal movement similarly to an actual boom
    • a second double set of motors, which allow a pitch movement, and which rotate with respect to an axis orthogonal to the axis of rotation of the first set of motors.
    • a counterweight to balance the forces
    • a vibrator which, in accordance with the type and frequency thereof, can indicate to the user the existence of a drawback or not at the time of performing the intended movement.

A position sensor or decoder has been included in all the motors with the aim of suitably determining the motor position with respect to its axis of rotation.

The system wherein the haptic control device is integrated also comprises:

    • Information subsystem comprising:
      • Database with 3D models of all the elements necessary in a refueling operation (booms, planes, etc.).
      • Expert system including information on the operation (forbidden movements, recommendations, etc.).
    • Perception subsystem comprising:
      • Image capturing means. Redundant system in charge of the visual capture of information relating to the operation. The system is prepared to combine several types of visual information.
        • Image capturing with structured lighting: a sequence of images captured with a set of cameras at a predetermined rate of frames per second.
        • Image capturing with cameras with time of flight (ToF) sensors.
        • Information from cameras from the standard instrumentation of reloading aircraft. The system allows the connection of the cameras found as standard in these aircrafts, suitable for the initial phase of the reloading operation, when the aircraft to be refueled is more than 15 metres away. This information shall be used to provide additional redundancy to the system.
      • Contextual information system. Sensor system which captures information from the environment of interest for the operation (GPS position of recipient aircraft, GPS position of reloading aircraft, relative boom-humidity receptacle distance, temperature, wind, movement sensors of the actual boom, etc).
    • Analysis subsystem. It is the fundamental part of the invention and allows creating a 3D model of the operation stage in real time (maximum 2 frames' delay), from analysis of the data provided by the perception system. In particular, using image analysis method with structured lighting on a combination of images captured and the information of the location of the recipient plane, it makes it possible to perform a virtual positioning of a 3D model of the recipient in the surroundings of the boom.
    • Smart refueling system. From the result of the analysis performed by the previous subsystem, and using the information of the expert system in refueling operations, this system determines and updates in real time:
      • The recommended sequence of movements to be executed to successfully perform the information.
      • The set of movements to prevent (broken down into actions).
      • The set of movements to hinder, and to what degree (broken down into actions).
    • Haptic remote control subsystem as previously described.
    • Feedback subsystem. Its mission is to produce in the haptic remote control subsystem actions that reflect both the effect of the environment (e.g. the wind force on the system), and the regulatory and recommended strategies for performing the operation (expert refueling operation system). For this reason, we distinguish 2 parts:
      • Boom-Haptic subsystem feedback. A set of sensors in the actual boom captures the forces that the actual boom is subjected to and turns these forces into actions on the control motors of the haptic subsystem.
      • Smart refueling system-Haptic subsystem feedback. The smart refueling system determines in real time the set of movements to favour and hinder and to what degree and translate the set into a series of actions on the control motors of the haptic subsystem.

Unless indicated otherwise, all the technical and scientific elements used in the present specification have the meaning typically understood by the normal person skilled in the art to which this invention belongs. In the practice of the present invention, it is possible to use processes or materials which are similar or equivalent to those described in the specification.

Throughout the description and the claims the word “comprises” and its variants are not intended to exclude other technical characteristics, additives, components or steps. For persons skilled in the art, other objects, advantages and characteristics of the invention will be inferred in part from the description and in part from the practice of the invention.
