Description

Automatic target-scoring system and method based on shock wave sensor

Technical Field

The invention belongs to the technical field of analysis and processing of firing practice results, and particularly relates to a method for accurately acquiring and processing firing result data by using a sensor to solve the problems of wrong report, missed report, mixed report and the like of the conventional automatic target scoring system.

Background

At present, an automatic target scoring system used in the actual firing training of troops mainly adopts target scoring methods such as shock wave target scoring, grating target scoring, image acquisition and the like to obtain information such as the number of hit rings, hit time, hit sequence and the like of each projectile, but the above methods are only limited to the case that the projectile normally hits a target (target surface). In practice projectile shooting training, the condition that the projectile is not attached to a target (target surface) frequently occurs, for example, a part of the projectile is easy to fly off due to the psychological influence of shooting or poor skill mastering of a new soldier; the slamming of the trigger when the shooter of a pistol fires causes the projectile to be greatly deflected "on the spot", etc. Statistically, projectiles exhibiting these conditions account for about 8% to 15%. When this occurs, existing automatic target scoring systems default to "no shooter" because no "signal" is captured, which results in missed reports and necessarily results in all missed target scoring for the hit sequence of subsequent projectiles.

In addition, the shooter can not distinguish the targets and generate 'mixed report' if more than two shooters shoot the same target, which seriously influences the target report information of other shooters (normal shooters) without shooting the wrong targets. Under the condition of no discrimination, when the performance of a normal shooter is counted, the current method is to calculate the actual shooting number with a higher ring number on the target. This clearly has a large deviation from the actual hit (or miss) information, thereby affecting the benefit of live-action shooting training. Meanwhile, the situations of miss-target, order dislocation, mistaken striking, no separation and the like not only influence the accuracy of target-striking information, but also are difficult to trace the real shooting situation and ammunition consumption situation, and influence the safety management and control of ammunition.

Example 1

The embodiment utilizes the system to be applied when a shooter shoots wrong targets in live ammunition. When the projectile hit information and the projectile launch information are matched in quantity and time (the difference between the launch time and the hit time is the flight time of the projectile, and the time difference between the launch time and the hit time is constant under the condition that the distance and the initial speed of the projectile are constant), judging that the projectile normally hits; when the information of the projectile launching number and time is generated and the information of the target hitting number and time is not generated, the projectile of the shooter (A) is off-target, the mathematical computer calls other target hitting information to be compared with the projectile launching information, if the target hitting information of the shooter (B) is matched, the shooter (A) is mistakenly hit and hits the target of the shooter (B), the mathematical computer automatically counts the projectile into the score of the shooter (A), and sends an instruction to the alarm through a wired or wireless mode to prompt the shooter to re-identify the correct target in time.

Example 2

The embodiment is applied to the practice shooting by using the system when a certain shooter shoots off the target and misses the effective target-scoring area of the target (namely, the system is used for flying). Shooting 5 bullets by a shooter (A), wherein the 1 st, the 2 nd, the 4 th and the 5 th bullets hit the target normally, but the 3 rd bullets are in a situation of 'flying' and causing miss, the shooting information subsystem transmits the obtained shooting data to a mathematical computer, the mathematical computer verifies the target (surface) report data, and when no shooting (or miss) information is obtained, the shooter (A) is judged to miss or miss the target. The mathematical computer excludes the target miss of the shooter (A) according to the implementation method steps of the specific example 1, thereby finally judging that the 3 rd shot of the shooter is off-target. The embodiment effectively avoids the situation that the hit data is not captured and the existing automatic target scoring system is silent under the above conditions, when the subsequent 4 th bomb normally hits, the score of the 4 th bomb is wrongly recorded as the score of the 3 rd bomb, the score of the 5 th bomb is recorded as the score of the 4 th bomb, the miss of the 5 th bomb shot by the shooter (A) can not be accurately reported, the situations that the 3 rd bomb is missed, and the sequence of the two latter bombs is wrong are generated, and the shooting score of the shooter (A) is further influenced. Moreover, in the process of firing practice, the shooter can observe the hit information on the target scoring system when shooting 1 shot, so that the attention of the shooter can be greatly dispersed, the psychology of the shooter is influenced, and the shooting practice is not good.

Example 3

In the embodiment, a plurality of shooters shoot a plurality of recurrent invisible targets in the cooperative shooting training of the fighting team by utilizing the system. For example, there are 3 shooters numbered X1, X2, X3, respectively, and 6 targets (targets) numbered Y1, Y2, Y3, Y4, Y5, Y6, respectively. When the same target is shot by different shooters for multiple times at different occasions, the conventional target scoring system can only calculate the total number of hits of a fighting team to the target, and by utilizing the method, the information such as the number of rings, the number of shots, the time and the like of each target hit by each shooter can be accurately reported according to the target number and the target position number of the shooter, and the system can calculate and judge the intensity of the target (target) to be killed according to the number of the hit rings, wherein if the target Y5 is damaged, the target Y5 can be judged to be lightly damaged if the 1 st hit Y5 of the shooter X2 is 7 rings; the target Y5 still has the fighting capability and can display the target again, and when the 2 nd hit of the shooter X1 is 10 rings, the target Y5 can be judged to be eliminated and no longer displays the target. Therefore, the invention can effectively enhance the benefit of the cooperative shooting training, and can realize accurate analysis and restore the actual hit condition by using the automatic target-reporting method in the cooperative shooting training.

Example 4

"shot firing time" (t) in the present example _Launching ) The time that the shot is shot from the muzzle at high speed under the action of gunpowder gas after being fired is detected by a shock wave sensor, and the shot hit time (t) _{Hit in} ) Refers to the time when the projectile is detected by the automatic target scoring system when contacting the target (surface). The difference (t) between the time of projectile (shot) hit and the time of projectile launch,

t＝t _{hit in} -t _Launching

Mainly composed of gun and targetThe distance of the projectile, the projectile discharging speed, the wind resistance, the capturing time of the shock wave sensor, the target-scoring reaction time, the data processing time and other factors, wherein the wind resistance is a variable factor, so the value t is not a constant value. Because the wind resistance is the same at the same time, when the data of the possible miss-target are compared by the digital computer, the t value can calculate the shot hit time (t) of the possible miss-target according to the t values of other target positions in the same round of shooting time period _{Hit in} ). For example, when 10 shooters are respectively positioned at 10 shooting target positions, the numbers of the shooters are sequentially X1, X2 and X3..... Times X10, and respectively correspond to 10 targets such as Y1, Y2 and Y3 … … Y10, and when the shooters X2 and X5 respectively send out 1 off-target (the targets have no target-reporting data), the mathematical computer calculates and calculates the target hitting time of the projectile shot by the shooter X2 according to the average value of the t values of the rest 9 shooting target positions, and if no hit information exists in the calculation time, the projectile shot by the shooter X2 is judged to be off-target; further, the mathematical computer determines whether shooter X2 made a wrong target according to the implementation method steps of "example 1".

Example 5

In this embodiment, the time data acquisition is accurately recorded as t _{Accuracy of measurement} And second. And when two shooters fire at the same time, one shooter goes off the target and the other shooter goes wrong at the same time. According to the statistics of a large amount of sample data, when the number of bullets shot to a fixed target is n, the total shooting time is t according to the outline requirement _{General (1)} Let us say that when the shooter shoots the ith shot, the use time is recorded as t _i (i =1,2, …, n) then there are:

further, the average miss ratio is

The average wrong targeting rate is->

The probability P of the above occurrence is:

when the hidden and displayed target is shot, the target display time is set as t _{Display device} Second, using the number of shots n ₁ Each time of firing n ₂ Repeating, when N shooters take part in shooting, the probability P of the above occurs _{Invisible and visible display} Comprises the following steps:

therefore, when the time data acquisition is accurate to 0.01 second, when two shooters fire at the same time, one shooter is off-target and the other shooter is wrong. According to a large amount of sample data statistics, 5 bullets are shot on a fixed target, the total use time of a shooter after 5 times of shooting is not designed to be 126 seconds, namely:

when 10 shooters take part in shooting, the probability of occurrence is as follows:

when the invisible target is shot, the target display time is 6 seconds, 10 bullets are used, 2 bullets are shot at each time, and when 10 shooters participate in shooting, the probability of the above situations is as follows:

it can be seen that the specific case has extremely strong operability.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions deviate from the technical solutions of the embodiments of the present invention.
