Description

Firing simulation evaluation method and device of direct-aiming weapon simulation terminal

Technical Field

The embodiment of the invention relates to the field of military simulation, in particular to a firing simulation evaluation method and device of a direct-aiming weapon simulation terminal.

Background

The flight path of the projectile of the direct-aiming weapon is basically a straight line, so that the projectile has the characteristics of straight trajectory and close range, such as light weapons. The light weapon belongs to one of direct-aiming weapons, and generally refers to firearms and other various weapons which are carried by individual soldiers or teams to fight.

Military training is a method for improving the operational skills of soldiers by skillfully operating weapons, but the actual projectile direct aiming weapons have the killing property and can only be realized through a military simulation training process. Therefore, a virtual station yard environment needs to be created, so that trainees can visually and auditorily and really experience the battlefield environment and become familiar with the environmental characteristics of the area to be battled. Weapon simulation terminals are an indispensable ring in the virtual yard.

However, in the existing simulation training, whether a trainee is hit is judged by judging whether the trainee is irradiated by a laser spot, and the influence of factors such as air resistance and meteorological environment on the bullet flight trajectory is not considered. Such an analog method has the following problems:

firstly, the light speed is far greater than the bullet speed, and in the light bullet replacing scheme, the shooting is hit, the bullet flight time is not available, and as long as the hit target is on the straight line at the shooting moment, the shooting is hit, the distance problem is not available, and the evasion possibility is not available. Secondly, the light is transmitted along a straight line, no bullet falls, the aiming mode of the weapon is different from the actual use condition, and if the method is used for training, the soldier is easy to confuse the technical and tactical actions. Also, there is a divergence angle of light, and the larger the coverage area the farther away, the easier it hits, just as opposed to a bullet hit.

Due to the problems, the training process and the hit result have larger deviation with the real training process and the bullet hit result, and finally the simulation training process can not achieve the expected effect.

Fig. 1 shows a flowchart of a firing simulation evaluation method of a direct-aiming weapon simulation terminal according to an embodiment of the present invention.

The method comprises the following steps:

s101, confirming the through-view relationship between the direct-aiming weapon simulation terminal and the struck target through laser emission.

The direct-aiming weapon simulation terminal responds to the firing command and emits laser with a band code, and the laser code information comprises information such as ranging information, type and number of a firing weapon, ammunition information, weapon user number and the like. At the firing moment, the central data processing center receives three-axis position information of the direct-aiming weapon simulation terminal, wherein the three-axis position information is longitude, latitude and height; and three-axis attitude information, namely a course angle, a pitch angle and a roll angle. Through the six information, the spatial position and the direction of the barrel of the direct-aiming weapon can be determined.

Due to the characteristics of the direct aiming weapon, after firing, firstly, the through-vision relationship between the simulation terminal of the direct aiming weapon and the struck target needs to be established, and further, the through-vision relationship between the laser emitter and the struck target needs to be established. The through-vision relationship is used for judging whether the direct-aiming weapon is possible to hit the hit target, namely, only if the direct-aiming weapon is in the through-vision relationship with the hit target, the direct-aiming weapon can be aimed at the hit target and is shot when the direct-aiming weapon is shot, so that the hit target is hit. If the direct aiming weapon and the hit target do not have a through-view relationship, the hit target cannot be aimed from the direct aiming weapon end, and cannot be hit.

In this embodiment, the determination of the see-through relationship is confirmed by laser emission, that is, if the hit target receives laser information emitted by the direct-aiming weapon simulation terminal, the direct-aiming weapon simulation terminal and the hit target see through.

As an embodiment of the present invention, optionally, it may also be determined whether there is a blocking object between the direct-aiming weapon and the hit target by using a laser ranging technique.

S102, when the direct-aiming weapon simulation terminal is in communication with a target to be struck, calculating the center position of a light spot of the direct-aiming weapon simulation terminal, which irradiates the target to be struck, and calculating a bullet simulated flight trajectory according to the center position of the light spot.

S102, under the condition that the direct-aiming weapon simulation terminal is in communication with the hit target, if the direct-aiming weapon simulation terminal is not in communication with the hit target, the laser spot cannot be irradiated to the hit target, and the simulated hit cannot be realized.

According to the judgment in S101, when the direct aiming weapon simulation terminal and the hit target are viewed, the direct aiming weapon simulation terminal is shot and emits laser. The emitted laser is a target light source, the target light source has a corresponding striking target, and the definition of a set of positions from which the target light source can irradiate the struck target to the light source is as follows: b = and B (z), wherein B (z) is a light spot position corresponding to one photoelectric receiver on the hit target which can be irradiated by the target light source; and collecting all photoelectric receiving corresponding spot positions of the target light source which can be irradiated on the struck target to obtain the spot positions of the target light source which can be irradiated on. And receiving light spots corresponding to the laser by a plurality of photoelectric receivers arranged on the hit target. There may be one or more than one of the photoelectric receivers arranged on the hit targetAnd the plurality of photoelectric receivers receive the light spots correspondingly irradiated by the laser, and the light spot set irradiated by the same target light source and received by the photoelectric receivers of the hit target is defined as A. Collection

Wherein A is _i The light spot set irradiated by the target light source received by a photoelectric receiver of the hit target. For example, 10 photoelectric receivers are provided on the target to be struck, wherein the photoelectric receivers 1 to 3 receive light spots, A respectively, irradiated by the target light source ₁ 、A ₂ 、A ₃ If the set A is A ₁ 、A ₂ 、A ₃ 。

Further, the intersection C of the set a and the set B is calculated, namely:

C＝A∩B

wherein, C is a light spot set of the photoelectric receiver of the hit target irradiated by the target light source.

In the above embodiment, the set C obtained after intersection of the set a and the set B is a ₁ 、A ₂ 、A ₃ 。

Further, the center point of the range covered by the set C is calculated. The central point is the central position of a light spot irradiated by the direct-aiming weapon analog terminal to the struck target.

In the above embodiment, the set C that has been obtained contains A ₁ 、A ₂ 、A ₃ And A is ₁ 、A ₂ 、A ₃ The corresponding photoelectric receiver arranged on the hit target is fixed in position, and the central positions of the photoelectric receiver, the photoelectric receiver and the hit target can be calculated according to the three positions, namely the central point of the coverage range of the set C.

Further, after the central position of a light spot irradiated to a hit target by the direct-aiming weapon simulation terminal is calculated, a bullet simulated flight trajectory is calculated according to the central position of the light spot. The process is as follows:

the bullet flight air resistance and the exit angle of the bullet need to be calculated.

The bullet flight air resistance is as follows:

And the exit angle of the bullet is determined by the central position of a light spot irradiated to the hit target by the direct-aiming weapon simulation terminal and the height difference between the exit angle of the bullet and the exit port of the direct-aiming weapon simulation terminal, so that the exit angle of the exit port is obtained.

Further, the bullet type information is contained in the light spot information, and therefore the quality of the bullet is determined. Therefore, the acceleration generated by the air resistance in the z-axis direction is calculated from the mass of the bullet as:

wherein m is the bullet mass; f (t) is air resistance in the z-axis direction; theta is the exit angle of the bullet; and t is the time of flight.

Finally, calculating the simulated flying trajectory of the bullet as:

therein, Ψ _x As a function of the fraction of the bullet projectile spread in the x-axis direction; psi _y Respectively, as a function of the fraction of the bullet projectile spread in the y-axis direction; v ₀ The initial velocity of the bullet; t is the time of flight; theta is the emergent angle of the bullet, namely the included angle between the emergent direction and the horizontal plane; g is the acceleration of gravity; f (t) is air resistance in the z-axis direction; m is the bullet mass; delta. For the preparation of a coating _x 、δ _y 、δ _z Influence coefficients of the spatial meteorological data in the directions of the x axis, the y axis and the z axis respectively; the z-axis direction is the horizontal direction along which the bullet advances, the y-axis direction is the direction perpendicular to the horizontal plane, and the x-axis direction is the direction perpendicular to the y-z plane.

S103, performing collision deduction on the bullet simulated flight trajectory and the action path of the hit target, and judging whether the hit target is hit or not.

In step S102, the bullet simulated flight trajectory has been calculated, the action path of the hit target is uploaded in real time, and it is deduced whether the bullet simulated flight trajectory and the action path of the hit target coincide at the same time point in the same time dimension, and if so, the hit target is hit at the time point; otherwise, the hit target and the bullet simulated flight trajectory are not repeated at any time point, and the hit target can be judged not to be hit.

Because the judgment of whether the hit target is hit is based on the collision deduction of the bullet simulated flight trajectory and the action path of the hit target, and is not based on the collision deduction of the laser irradiation light spot and the action path of the hit target, the influence of wind resistance and meteorological factors on bullet flight can be considered, and the real hit result can be really restored.

And S104, when the hit target is hit, calculating a hit position, and matching the damage condition corresponding to the hit target from the damage comparison table according to the bullet type and the hit position.

The damage condition is determined by the bullet type and the hit position, and the damage degree of different bullet types is different; the extent of damage varies from hit to hit. And presetting a damage table, wherein the damage comparison table at least comprises three fields, namely a bullet type, a hit position and a damage condition. By matching the bullet type and hit position, the damage situation is mapped out. The hit positions are mainly divided into three categories, head, torso and extremities. And dividing the regions according to the three types of regions, wherein the hit position falling in the corresponding region is the hit region. The bullet types comprise pistol bullets, rifle bullets, sniper rifle bullets, class machine gun bullets and the like; the injury condition includes fatal injury, critical injury, severe injury, moderate injury, light injury, etc. The specific damage ratio table can be drawn up as required, as shown in table 1:

TABLE 1

As an embodiment of the present invention, the injury comparison table may further include a rescue result field. As shown in fig. 2, the method further comprises:

and S105, matching a rescue result corresponding to the damage condition from the damage comparison table after matching the damage condition.

The rescue result comprises unrepairable combat capability, recoverable moderate injury state after a plurality of hours, unrepairable combat capability and the like. The specific rescue result can be drawn up as required, and a table for comparing injuries drawn up as required is given below, as shown in table 2:

TABLE 2

In the embodiment, the central judging subsystem determines the hit damage according to the bullet type and the hit position, issues the damage condition and the rescue result to the hit target in the form of damage informing message, and limits the hit target to weapons and/or actions. For example, if the hit target cannot recover the fighting ability for the rescue result, the hit target is locked.

According to the embodiment of the invention, the influence of factors such as air resistance, meteorological environment and the like on the bullet flight trajectory can be considered, and the bullet simulated flight trajectory close to the reality is calculated, so that the hit result close to the reality is deduced, and the hit result is more accurate; and the damage condition can be evaluated, and the damage result of the hit target can be fed back.
