Description

The technical field to which the invention relates.

The invention relates to the field of imitation of affection during training in shooting and training under conditions of bilateral exposure. The level of technology.

The prior art has an analogue of the “Laser Simulator Shooting System” (patent RU 2347171, 05/27/2008), where, as a method for determining the extent of a lesion, a target is described, which contains several receivers of a laser signal located on the equipment in accordance with the lesion zones form of photodiodes.

The degree of damage is calculated in the unit of signal processing by a specific algorithm. Depending on the number of hits and affected areas, the degree of damage can be indicated by the light indication unit through the ignition of LEDs of a certain color corresponding to the degree of damage, for example:

- yellow color - slight injury;

- green color - moderate wound;

- blue color - severe wound;

- red color - mortal wound.

The disadvantage of the known invention is the low accuracy of determining the degree of destruction of the target, due to the lack of information about the degree of protection of the point of impact, namely the presence or absence of personal protective equipment in the form of small arms in the form of helmets and body armor.

The closest analogue is the utility model “Device for conducting games that simulate shooting” (patent RU 9400 U1, cl. A63B 71/02, 03/16/1999), which includes determining the degree of damage using the degree of damage, which is damage is determined by taking into account information about the point of impact, distance, type of weapon, the degree of protection of the point of impact.

The degree of protection of the point of entry is set at the beginning of the game for each player by the allowable number of defeats (viability) and the ability to automatically adjust the specified parameter in various game situations.

However, the specified viability parameters are set manually with control on the digital indicator of the dynamic display unit, after which manual input is sealed, and automatically adjusted in various game situations with the ability for the player to periodically control this information and do not depend on the availability of personal protective equipment, reducing the most reliable determination of the degree of damage.

Also, the analogue in the transmitted laser beam from the weapon simulator to the target player does not have information about the unique number of the shooter, the type of weapon from which the shot was fired, the firing range.

In addition, the replacement of hardware logical blocks "AND, OR, NOT" present in the analogue by software allows for the ability to customize the software for the training participant’s equipment without replacing it. (Exercise participants may be without personal protective equipment, only in a helmet and / or body armor).

Disclosure of the invention.

The technical result is to increase the reliability of determining the degree of damage when simulating firing using a laser simulator with an accuracy of up to two diameters of a weapon, provided that the participants have personal protective equipment in the form of body armor and helmets of different degrees of protection.

The high accuracy of hitting up to two diameters of the caliber of a weapon is due to the need to determine the affected area covered or not covered by personal protective equipment. The specified accuracy and initial parameters for calculating the degree of damage (information on the point of impact of the laser simulator of firing, distance, type of weapon, degree of protection of the point of impact) will allow to achieve the required accuracy when calculating the degree of damage.

The technical result is achieved by determining the degree of damage based on the damage caused on the basis of information about the point of impact, distance, type of weapon and degree of protection of the point of impact, using an algorithm for determining the degree of damage and a table of possible states, including whether the specified point is covered by individual means protection.

In this case, individual means of protection against small arms can be a body armor and / or a helmet of varying degrees of protection.

Signs used to characterize ways.

The method of determining the degree of damage when simulating firing using a laser shooting simulator is based on applying information about the point of impact of the laser shooting simulator beam, distance, type of weapon, degree of protection of the point of impact to determine the damage and further calculation using software that information determines the degree of damage by selecting according to the algorithm for determining the degree of damage (Fig. 1) and in accordance with the table of possible states (Fig. 2).

All states of the participant are displayed on a special display in the form of icons. In case of severe injury and death, the laser simulator firing the training participant is disconnected and a sound signal is given.

The method of determining the degree of damage when simulating shooting and damage using a laser shooting simulator is achieved by the following sequence of actions:

- obtaining information about the point of entry, distance and type of weapon;

determining the degree of protection of the point of impact from the influencing factors;

- determination of the damage caused;

- determination of the extent of damage based on the damage;

- visual and audible indication of the degree of damage as a set of states:

- efficient;

- easily injured;

- seriously injured;

- killed.

The implementation of the invention.

The method can be carried out as follows.

The laser firing simulator (LIS) (not shown) is mounted on the training participant’s weapon. The training participant chooses the type of weapon based on his position (shooter, machine gunner, etc.). In addition, the participant has infrared impact sensors with a receiving window diameter of not more than 20 millimeters (not shown), which are located on the helmet (from 3 to 5 pieces), chest (from 1 to 3 pieces), back (from 1 to 3 pieces), hands (1 piece each) and legs (1 piece each) and an electronics unit (not shown in the drawings) providing information exchange between LIS elements and the Learning Management Center (CLC) (not shown in the drawings). The LIS simulates a shot with a laser beam operating at a frequency of 0.9 μm and being safe for the eyes of the exercise participants. When imitating a shot, a laser beam is initiated when a weapon is fired with a blank cartridge. At the time of the shot, the range is measured using LIS, a status request (alive, killed) in the electronics unit and the formation of a signal sent by the modulated laser beam towards the enemy (another participant in the exercises). The signal transmits information about the unique number of the shooter, the type of weapon from which the shot was fired, the firing range.

When a laser beam hits an enemy's infrared sensors, the signal is converted into a digital form and transferred to the opponent’s electronics unit with the addition of sensor numbers that recorded this hit. Based on information about the type of weapon, firing range, point of entry and degree of protection of the point of impact (this point is covered with a helmet or body armor or not), the electronics unit calculates the degree of damage according to the presented algorithm (Fig. 1 and Fig. 2). After calculating the degree of damage depending on the change in the status of the participant in training (alive, easily injured, seriously injured, killed), several variants of events are possible:

1. if it is seriously injured or killed, an audible alarm is issued and the laser simulator fires on the participant’s weapon, the participant’s status is displayed (seriously injured, killed);

2. if it is lightly injured, an audible alarm is issued and the status of the participant is displayed on the information display (easily injured).

We give an example of calculating the degree of damage using the algorithm (Fig. 1 and Fig. 2).

A participant armed with an LIS mounted on a Kalashnikov assault rifle, such as the AK-74, fires at a conventional enemy from a certain distance, for example, 400 meters. At the moment of imitation of a shot, a laser beam with a modulated signal containing information about the unique number of the shooter, type of weapon (AK-74) and firing range (400 meters) hits, for example, the enemy's infrared sensor located on the left side of the chest. It is determined that this part is covered with a bulletproof vest. In the future, according to the table (Fig. 2), the vector for calculating the degree of damage is determined. In our case, the program for calculating the degree of damage selects from the table the state corresponding to the given set of incoming information (type of weapon is AK-74, distance is 400 meters, and the point of entry, taking into account the degree of protection, is falling into the armor jacket plate). This set of incoming information corresponds to vector 1, which according to FIG. 1 defines the extent of the lesion as "slightly injured." The electronic unit emits a signal that the participant has received a defeat and displays the information on the extent of the damage.

The described method for determining the extent of damage can be applied in combat reality imitation systems when learning to fire under conditions of bilateral interaction, taking into account that the trained personnel have individual means of protection against small arms. In addition, this method can be implemented to determine the extent of damage to armored vehicles and trainees located in it. This allows you to conduct classes in combat training of ground forces in conditions as close as possible to combat.
