The invention relates to targets of simulators for training shooting firearms without the use and application of ammunition.

There is a method of tracking radiation source [1, 2], based on the use of position-sensitive semiconductor elements. Luminous flux from the radiation source is focused by the lens, causes a change in voltage on the collector of the tire depending on the coordinates of the light spot on the surface of the photodetector. The disadvantage of optical-electronic targets based semiconductor position-sensitive element is a low accuracy due to the nonlinearity characteristics and thermal instability. In addition, the existing level of production technology did not allow to obtain a position-sensitive elements with the required and identical parameters.

Known target [3], comprising a laser emitter mounted on the weapon, and television receiver (camera)fixed in front of the screen (the target) of the simulator. Pressing the trigger on the screen from the laser light spot is formed at the point of contact. The coordinates of the spots are determined by using cameras. The disadvantage of this device is the low accuracy because of the low resolution cameras. The size of the field of registration (target) is limited because the exhaust gas is Anikanova field of view of the cameras. Increasing the angle of the field of view of the camera leads to the increase of error (sampling). In a group fight you can match different shots shooters. Simultaneous determination of the coordinates of their points of guidance is impossible. Even in case of discrepancy between shots it is necessary to organize the functioning of the recording equipment to identify which of shooters matches the given shot.

Known for shooting training Kudryakov [4], containing the radiation source, is made in the form of a sector of a target mounted on small arms opto-electronic light receiver associated with the amplifier and processing circuitry of the signal. Target made four quadrant with X-shaped arrangement of sectors and modulated by the radiation of each of its sectors, which allows of the total signal at the output of the radiation detector to extract signals corresponding to the sectors of the target. Opto-electronic receiver consists of a collecting lens, the main focus of which is located aperture with a calibrated orifice, and a solar cell (sensor). The amplitude of the selected signal is directly proportional to the projected area of the target sector on the photocell sensor. The optical axis of the photodetector from the center of the target causes a redistribution of the amplitude C is achene, to determine the magnitude of this bias i.e. the coordinates of the point of guidance. The disadvantage of this device is the difficulty of ensuring uniform illumination of the target sectors due to the heterogeneity of the radiation in different directions, especially in the case of the large size of the target, and because of the heterogeneity of the irradiated target material, as well as the relatively small size of the target, the limited field of view of the opto-electronic receiver.

The closest analogue is shooting training with opto-electronic recording device US patent No. 4583950, which contains a set of training weapon with the trigger mechanism is configured to close the electrical circuit when the trigger is pulled, the opto-electronic converters, the source and the radiation detector. The disadvantage of this simulator is the low accuracy, the inability to uniquely identify the causes of poor implementation shooting trainees (obstruction of weapons, incorrect relative position of the front sight and rear sight, poor retention of the aiming point).

The purpose of the invention is to eliminate the disadvantages of the known devices by creating a shooting simulator based on serial video cameras placed on the sets of military weapons and connected to you is to slitely, ensuring high accuracy of definition of coordinates of a point contact, the display on the virtual target point of contact during penetration of the guidelines in the field of a given target, as well as the formation of the virtual target trajectory of the moving point from the moment of pressing the trigger until the moment of shutter release trigger, output to the monitor picture (the relative location of the front sight and the rear sight against the background of the target, the point of hitting targets in a given time, roll (tilt) weapons, which the learner sees through the weapon sight, as well as the automation of the learning process and the assessment of the actions of the learner.

The task is solved in that in shooting simulator containing the weapon with the trigger mechanism is configured to close the electrical circuit when the trigger is pulled, the opto-electronic converters, the source and the radiation detector, target field, put the transmitter, the display device results, speakers and two micro switches, the first of which is rigidly fixed on the butt of the gun under the trigger, the second microswitch is rigidly fixed on the grip below the trigger with the ability to close the electrical circuit when cocking the hammer, both microswitch connected in series and connected to the input of the transmitter, on the arms on the bracket under the trunk o f the and camcorder, which is connected to the video input of the transmitter, the display device results and speakers connected to the output of the transmitter, the target field is set to the distance specified in real-world shooting, target field has a conventional paper targets, weapons in the shooting mode is fixed in the grip, and the shooting mode is in the hand of a student.

The drawing shows the device simulator.

The device contains a computer (PC) 1, the output of which is connected a display device (monitor) 2, a set of military weapons 3, under the trunk on which the bracket is placed the video camera 4, under the trigger 11 is fixed microswitch 5 commit pressing the trigger 11, under the hammer 10 is a microswitch 6 fixing cocking the hammer 10, the target field 7 installed at the distance specified in real-world shooting, target field 7 is placed a conventional paper targets, the grip 8 for fixing the arms 3 when performing the adjustment, to the second output of the transmitter 1 is connected speakers 9.

The device operates as follows. After switching on the machine the computer 1 provides output to a display device (monitor) 2 window signal from the video camera 4 (target field 7) and the virtual image of the target. At the beginning of the work with the simulator is vereesa the line of sight, what weapon 3 is installed in the grip 8, the combination of a line through the front sight and rear sight with the bottom outer border of the "eight" of the target, after which the arms 3 is fixed in a Vice. The image of the target fields 7 through the video camera 4 and the transmitter 1 is transmitted to the monitor 2. After translation of the transmitter 1 in the mode of "ZEROING" in it remember the coordinates of the center of "dozens" of the selected target. After the transfer evaluator in the mode "SHOOTING" the simulator is ready for firing. In this mode, the image obtained from the video camera 4, the transmitter 1 determines the offset of the guidelines on the X-axis and Y-axis relative to the baseline obtained in the shooting mode. The offset is determined by considering the angles dam of 3 weapons. Frequency calculations - 25 measurements per second. When a platoon of trainees trigger 10 weapons 3 press the button of the microswitch 6, which closes its phase electrical circuit and prepares to fire. Shooter starts aiming. When the line of sight passes through the given target, the computer 1 starts the calculation of the coordinates of the point of impact at 25 calculations per second. On the basis of these calculations on the virtual target image formation point of ingress and "eight" target depicted front sight and the rear sight, the relative location of which depends on the fact, in what area is the point of contact. In addition, is determined and displayed on the monitor 2, the direction and angle of obstruction of the arms 3. This information allows the educators to see the target through the eyes of a student, and in the process of training in a timely manner to indicate errors and seek to address them. By aiming the shooter smoothly presses the trigger 11. After you select free running through the trigger 11 is pressed is transmitted to the button of the microswitch 5, which closes the whole chain. This condition is fixed by the transmitter 1 and serves as a signal to start recording with a frequency of 1 point per second trajectory of the moving point on the virtual target. While the position of the point of contact with the target area is not the "nines" is accompanied by the melodious sound signal, but beyond rude sound. At the time of the descent of the hammer 10, the circuit is opened, which is perceived by the evaluator as a shot and a command to issue corresponding audio signal and immediate calculation of the coordinates of the point of impact, which is applied to the virtual target and is highlighted. All the points plotted on the virtual target, which is joined by a line. The coordinates of the points plotted on the virtual target, the appropriate relative position of the front sight and rear sight, and the direction and angle of obstruction of weapons is upominayutsya. Summation of points is carried out depending on the settings. Data on the arrow and the results of the exercise are remembered calculator that allows RESULTS to view the results and analyze the errors made by the trainee while shooting. The results can be displayed on the virtual target button on the monitor, in the form of points, corresponding to the shots produced during exercise, and trajectory recorded in the memory of the computer points prior to the shot.

Thus, the implementation of the invention will reduce the time and financial costs to the shooting instruction, to improve the accuracy of determining the coordinates of the point of contact with the target, learning to see on the monitor screen picture, which the learner sees while aiming, and in a timely manner to indicate errors, and automate the learning process and the assessment of the actions of the learner.
