Description

The claimed programmable optoelectronic sensor of a shooting simulator refers to educational electronic training facilities designed for training and training in shooting sports, for example, bullet shooting from firearms and pneumatic weapons, crossbow and bow shooting, biathlon, etc.

So, from the prior art, a number of devices are known, which are shooting simulators and / or electronic devices designed to process information received from them.

RF patent No. 2640952 discloses the use of a high-speed video matrix and a programmable microcontroller in the sensor design, which allows to increase the speed and, accordingly, the accuracy in determining the coordinates of the aiming path and the location of the hole.

A disadvantage of the known solution is the impossibility of using this electronic simulator to analyze the actions of a shooter using ammunition - this software and hardware complex includes weapon simulators.

The closest solution is the optoelectronic device of a shooting simulator, disclosed in the patent of the Russian Federation No. 114768, where the task of ensuring the convenience of using a shooting simulator with an optoelectronic device while increasing the level of the automated training process and evaluating the learner's actions is solved due to the fact that the optoelectronic A device for a shooting simulator comprises a housing and a lens and an anti-reflective diaphragm, which are optically connected with a photosensitive sensor Tritz, placed on, or connected to a printed circuit board, which also has a microcontroller, in electrical communication with the photosensitive matrix and the microcontroller.

In this device, the sensor is mounted on the used weapon model or weapon model parallel to the barrel or line of sight. The simulator is used with a connected computer, laptop or mobile device. Connection can be made via a USB-connector, or via Wi-Fi or Bluetooth - through an optional adapter. A composite aspherical achromatic lens with an antireflective coating is installed inside the lens. It is possible to set the diaphragm of the field of view, which is used in high light conditions. Inside the case, the main board is installed, on which the electrical circuit of the device is made, as well as a microphone, accelerometer, microcontroller. A light-sensitive matrix optically coupled to an achromatic lens is installed on the board. The lens is connected to the housing by a threaded connection, which allows you to change the distance from the lens to the photosensitive matrix to set the distance to the target from 2.5 m to 1 km. The circuit board has a USB port to which a computer can connect. The housing cover is made of radiolucent material. The sensor, together with the software used in a computer or mobile device, is essentially a high-speed intelligent programmable video recorder that, according to the algorithms and parameters specified by the computer, performs primary processing of the data received from the video matrix and other data elements for further interpretation, display, storage and statistical processing to a control computer or mobile device. The main functions of the sensor as a part of the simulator: detection and recognition of a target by given parameters, formation of the coordinates of the aiming point relative to the center of the target, fixing the moment of the trigger trigger mechanism of the weapon (shot) and transferring this data online for further processing to a computer or mobile device. When the simulator is operating, the range from the sensor to the target is limited only by its angular dimensions, which allows real shooting at standard targets at a distance of 2.5 m to 2.5 km.

The disadvantage of the prototype is the impossibility of its use in wireless mode (Wi-Fi) without an additional adapter, the lack of information about the degree of impact on the trigger of the weapon, and the operability of the electronics used in the device when using the simulator in adverse conditions, for example, high humidity, precipitation, is not ensured .

Based on the shortcomings in the prior art of developments in the field of electronic training aids for shooting training, the technical task of the utility model was to improve the quality of shooting training by increasing the accuracy of the analysis of the shooter's actions.

The technical result achieved by the implementation of this utility model is to increase the speed of the entire system, as well as the possibility of using the sensor in adverse weather conditions.

The technical result is achieved due to the fact that the programmable optoelectronic sensor for the shooting simulator contains a lens and a housing with a cover, a printed circuit board is installed inside the housing, on which a photosensitive matrix is placed, which is optically connected with an aspherical achromatic lens and anti-reflective diaphragm, and is also located on the matrix programmable microcontroller electrically connected to the photosensitive matrix, the housing is connected to the lens by means of a threaded connection with the possibility of change According to the utility model, the distance from the achromatic lens to the photosensitive matrix contains a cover made of radio-transparent material, an accelerometer, a microphone, a USB connector are electrically interconnected, and the photosensitive matrix is a high-speed video matrix, while all the elements placed on the printed circuit board is configured to synchronously operate and transmit information to an external device.

The accelerometer, microphone and high-speed video matrix, which are electrically interconnected, located on the sensor circuit board, allow information processing, which ensures the speed of the programmable optical-electronic sensor of the shooting simulator. The main functions of the sensor: detection and recognition of the target according to the specified parameters, the formation of the coordinates of the aiming point relative to the center of the target, fixing the trigger moment of the trigger mechanism of the weapon (shot) and transmitting this data online via Wi-Fi or via a cable via the USB connector to a computer or mobile device.

The programmable optoelectronic sensor can be used either connected to a computer or mobile device, or independently. In this case, a mobile device is understood to mean any external device with specialized software installed.

The sensor can be connected to a computer or mobile device with special software installed at a distance via a USB port, which allows the trainer to analyze the athlete’s behavior at the time of training, and when connected to a computer, the device’s elements are powered by a computer and the battery is charged.

It is advisable that the programmable optoelectronic sensor of the shooting simulator be paired with a pressure sensor on the trigger of the shooting simulator. The use of a high-speed camera in conjunction with a trigger pressure sensor as an external device allows us to provide the most optimal version of the trigger pull dynamics for a particular athlete, to evaluate the uniformity and stability of “trigger release” as an important element in the production of a series of precision shots.

The sensor, together with the software used in the computer or mobile device, is essentially a high-speed intelligent programmable video recorder, which, according to the algorithms and parameters specified from the computer or mobile device, processes the data received from the high-speed video matrix and other data elements for further interpretation, display, storage and statistical processing in a control computer or mobile device.

The battery allows you to use the sensor in Wi-Fi mode - then the trainer can analyze the athlete's behavior during the shooting training. The operation of the sensor in Wi-Fi mode is most convenient for training and training in small sports.

The presence of the cover allows the use of a programmable optoelectronic sensor in adverse weather conditions, and its implementation from radiolucent material does not impede the operation of the Wi-Fi module installed on the printed circuit board, which ensures reliable operation and high performance regardless of weather conditions.

The claimed utility model is illustrated by drawings.

In FIG. Figure 1 shows the design of a programmable optoelectronic sensor of a shooting simulator in isometry (it is customary to first give an isometry, then cuts).

In FIG. 2 shows a sectional view of a design of a programmable optoelectronic sensor of a shooting simulator;

In FIG. 3 shows the design of a programmable optoelectronic sensor of a shooting simulator front view.

The sensor contains a lens (1) connected to the housing (4) by means of a threaded connection, which allows to achieve the optimal distance from the simulator to the target. A printed circuit board (8) is installed inside the housing (4), on which a high-speed video matrix (10) is placed, which is optically coupled to an aspherical achromatic lens and anti-reflective diaphragm (2) through a lens retainer (11) with a cover (18). The printed circuit board (8) also has an electrically interconnected accelerometer, a microphone, and a USB connector (5). Inside the case (4) and the cover (18), a printed circuit board with a Wi-Fi module (7) is installed. On the body (4), a fastening (17) of the "dovetail" type 7 mm was made, designed to install the sensor on various types of weapons. In addition, on the board (8) there are control and indication elements, under which holes are made in the case (4): the POWER on / off button (15), the MODE connection mode select button (13), multi-color mode indicators operation (16) and battery charge mode (14).

In order to optimally match the distance of the selected distance from the sensor to the target, a pointer ring is mounted on the lens (12). To set the distance to the target from 2.5 m to 1 km or more, and corresponding divisions are plotted on the body (4). After setting the required distance, the lens is fixed with a locking screw (19).

A USB connector (5) is installed on the printed circuit board, to which a computer can be connected via cable to work with the device or charge the battery (6), or external devices, for example, a pressure sensor on the trigger. The power of the device’s elements is carried out in Wi-Fi operating modes from the battery (6), and when working through the USB connector, from the connected computer.

The printed circuit board (8) provides synchronous operation and transmission of information to external devices, i.e. performs the functions of mechanical and electrical connection of the electronic elements of the sensor, i.e. provides their interaction and synchronous operation.

The photosensitive matrix, represented by a high-speed video matrix (10), provides the processing of graphic information obtained from the lens (2), that is, it detects, tracks, classifies and converts objects into computer code that can be processed by a microcontroller for further playback using electronic means and analysis of the actions of the trained athlete.

Aspherical achromatic lens (2) is a complex lens, consisting of two - collecting and scattering, glued together. An antireflection coating is applied to the outer surface of the lens (2).

The insert (3) is used to screw the lens into the housing

The sealing ring is designed to be fixed in a given place in the housing (4) of the photosensitive matrix, which is a high-speed video matrix.

At the beginning of the work session, the sensor microcontroller is programmed to the required operating mode depending on the type and parameters of the target and small arms. At the first aiming, pointing the weapon at the target area, the sensor detects and recognizes the target for calibrating the shot.

Calibration shot adjusts (combines) the optical axis of the sensor and the aiming point of the sights of the weapons used.

The programmable optoelectronic sensor can be used either connected to a computer or mobile device, or without connecting to any external device.

Via a USB connector or online via Wi-Fi, the sensor is connected to a computer or mobile device with special software installed at a distance, which allows the trainer to analyze the athlete’s behavior at the time of training, and when connected to the computer, the device’s elements are powered from the computer, as well as charging the battery.

When using a computer or mobile device with special equipment as an external device, during the production of test and test shots on a target displayed on the screen, the aiming point and the trajectory described by this point in the process of aiming and firing a shot are displayed. At the time of the shot, a virtual hole is displayed at the location of the aiming point and its merit is determined with an accuracy of 0.1 points. After the shot is fired and the target is removed from the sensor’s field of view, the trajectory is automatically reproduced on the screen and painted in different colors at different time intervals before and after the shot. At initial settings, more than 1 s - green, from 1 to 0.2 s - yellow, less than 0.2 s - blue and red - after the shot. This color allocation allows you to accurately and quickly analyze the actions of the shooter at different stages of the shot. It is especially important to highlight the intervals of the trajectory immediately before the shot with separate colors, when, in addition to stability and correct aiming, the result is affected by the dynamics of pressing the trigger. The color of the coloring of the intervals of the trajectory and their value can also be set individually in the software settings. The trajectory with a hole is stored in the computer's memory; it can be reproduced immediately after a shot or during further analysis.

Statistical processing, determination and output in the form of tables and graphs of various parameters of the trajectory allows you to analyze, compare and improve the main components of a successful shooting: stability, descent processing, the uniformity of manufacturing and aiming both a single shot and a series, evaluate and compare these indicators over a long period use of the simulator.
