Description

Mobile device and portable weapon training system

FIELD OF THE INVENTION

The present invention relates to the field of mobile solutions and training systems in the military industry. More specifically, the present invention relates to a new functional combination of a mock-up of a military weapon model on a natural scale, computer hardware and a display of a seemingly real environment, whereby the actual physical orientation of the trainee and his actions are reflected in a seemingly real environment. .

Background of the invention

Existing portable weapon training systems use large, dark projection screens and / or turrets. These systems enable the training of portable weapons handling procedures from the inspection and preparation of weapons to loading, rehearsing, measuring and firing. However, the use of large screens and domes significantly raises the price of the system and reduces its functional usability because such systems are difficult to move to other locations and are expensive to maintain.

Patent application WO213 / 111146, for example, provides a system for carrying out a training procedure during training in weapons in a virtual environment. The system includes one or more battle stations, one or more motion tracking devices that track the body movements of a trainee with school weapons, one or more processing units, and one or more display systems, the display system including one or more projectors and screens they surround the operational field of view, and project a virtual human fighter and enable a vivid depiction of the virtual environment. Battle stations are networked and allow a virtual human fighter to be mapped to one or more trainees in different battle stations.

A further example of an existing solution is given in patent application WO 2014/018561, where the user is equipped with a head-mounted display device that wirelessly receives real-time video signals transmitted by a radio transmitter connected to a computer separate from the weapon and trainee. The computer generates real-time video images, which are transmitted wirelessly to the main display device.

As follows from the above, there is a need for a highly mobile device and training system that would allow for quick installation and ensure easy installation and low maintenance costs.

Summary of the invention

The object and object of the present invention is to provide a mobile training device with portable weapons, for which the term training device will be used in the following, which enables quick installation, easy installation and low maintenance costs.

It is a further object of the invention to track a student's real-world rotations and translate them into virtual reality-relevant data, which can then be used to calculate the virtual-real environment and ballistics in real time and to display the virtual environment to the student.

Another further goal is to allow multiple trainees in the same or different physical locations to train simultaneously in the same or different virtual environments. This is achieved by connecting multiple training devices to the system.

The stated objectives and advantages are achieved by the device and training system according to the invention. The training device is suitable for all portable weapons that have a built-in optical sighting device and a trigger. A training device is a functional combination of a weapon model that is an exact replica of an actual weapon or external actual weapon case, customized computer hardware, a motion tracking sensor, hereinafter referred to as a motion sensor, custom software for a virtual real environment, and miniature monitor; all of which is integrated into one device.

All hardware components, including the integrated dedicated computer, hereinafter referred to as the integrated computer, shall be housed in the weapon model housing; they are preferably integrated into a frame which can also serve as a refrigerator if it is made of metal, preferably aluminum. Optionally, the frame can also serve as a holder for other components, ie for the motion sensor, battery cover and separate cooler. All machine components are mounted in the housing of the weapon model or preferably integrated into the frame in such a way that the electromagnetic waves of the individual machine components do not interfere with the operation of the motion sensor. A miniature monitor showing the seemingly real environment is built into the housing of the actual sighting device. The trigger is adjusted in such a way that the trigger of the weapon is communicated to the integrated computer. In this way, the training device allows aiming, selecting targets, preparing for a shot and shooting with a model of a weapon at a target in a seemingly real environment with several training positions, without additional means of visual display other than those integrated in the model of the weapon and her.

The motion sensor does not follow the parallel movements of the trainee and the mock-up of the weapon;

follows only the rotations of the training device about at least one axis, preferably about three axes.

Optionally adding hardware for Wi-Fi wireless connectivity to the training device can enable connection to a computer server, using the computer server to track and save the training for later retry or study, or to change the virtual environment parameters during the training itself. In addition, multiplayer communication software integrated into virtual real environment software allows multiple trainees, each equipped with their own training device, to train simultaneously in the same virtual environment either in the same or in different physical locations.

Detailed description of the invention

As shown in Figures 1 and 2, the training device is made in a mock-up of the weapon 10, which is an exact replica of the actual weapon or the actual weapon housing. The integrated computer 13 is mounted inside the model of the weapon 10, preferably in the frame 20, which is purposely designed to fit into the model of the weapon 10. The frame 20 can serve as a cooler if it is made of metal, preferably aluminum. The miniature monitor lla is integrated into the housing of the sighting device 11 and connected to the integrated computer

13. When the trainee looks at the sighting device 11, he is in fact looking at a miniature monitor lla showing the virtual real environment 33 generated by the integrated computer

13.

Trigger 12 is also an exact replica of the actual trigger of the weapon; in fact, the trigger 12 is connected to the integrated computer 13 and is adapted in such a way that the triggering of the weapon via sensors 43 is communicated to the integrated computer 13. The trigger 12 has an integrated power button 18, which serves only to turn on the training device. The motion sensor 14 is located in or on the weapon model 10, preferably mounted on the frame 20, connected to the integrated computer 13. The battery 15 is the only power source for all electrical components of the training device and provides up to 4 hours of autonomy with energy. The battery 15 is located in the model of the weapon 10, preferably on the frame 20 at the rear end of the model of the weapon 10. The battery 15 can be inserted through the insert slot into the battery housing 19, which allows easy and quick replacement of the battery.

An additional cooler 21 can be mounted on the upper side of the frame 20, preferably on its central part, designed to regulate the adequate air flow and ensure adequate cooling of the components. The trainee may also be equipped with a headset 17 connected to an integrated computer 13 to enable him to become even more immersed in the seemingly real environment through auditory stimuli 33.

The motion sensor 14 may be any prior art sensor capable of detecting rotations about at least one, and preferably about three, axes. As can be seen from Figure 3, in a preferred embodiment, the motion sensor 14 consists of at least one, preferably three separate sensing elements, an analog-digital sampling unit and a calculation and output unit 23.

Each individual sensing element detects rotation around one of the axes, so that all three sensing elements in combination detect the exact orientation 22 of the weapon model around the "X", "Y" and "Z" axes. The "X" axis represents the rotation about the horizontal longitudinal axis of the weapon model 10 held by the trainee, the "Y" axis represents the rotation about the transverse horizontal axis of the weapon model 10, and the "Z" axis represents the rotation of the weapon model 10 around the vertical axis.

The motion sensor 14 sends data to the integrated computer 13. When the trainee moves the weapon model 10, the motion sensor 14 detects the rotations of the weapon model 10 in the real world and communicates them to the integrated computer 13, where these rotations are translated into a virtual real environment 33. monitor lla.

The analogue-to-digital sampling unit converts the analogue signal of individual sensing elements into a digital signal of high integrity and accuracy. The analog low-pass filter ensures the elimination of "aliasing" errors, high-frequency noise, minimizes inter-channel delays and removes high-frequency components. A digital low-pass filter is used to prevent "aliasing" interference in the signal when the signal is converted to a lower resolution in the digital domain.

The computational and output block 23 performs accurate numerical calculation of the integrated quantities of angular velocity and acceleration by compensating t.i. "Coning" and "sculling" errors. The motion sensor 14 is integrated in / on the frame 20 and can detect the trainee's orientation without the trainee having to wear it on the body.
