Description

Technical Field

[0001] The invention belongs to the technical field of live-fire shooting performance analysis and processing, and specifically relates to a method for using a sensor device to solve the problems of wrong reporting, missed reporting, mixed reporting, etc. of an existing automatic target reporting system, so as to realize accurate collection and processing of shooting performance data. Background Art

[0002] At present, the automatic target reporting system used in live-fire shooting training of the troops mainly adopts shock wave reporting, grating reporting, image acquisition and other reporting methods to obtain the number of hits, hit time, hit order and other information of each projectile, but the above methods are only limited to the situation where the projectile hits the target (target surface) normally. In live-fire shooting training, the situation where the projectile does not hit the target (target surface) also occurs frequently. For example, due to the psychological influence of shooting or poor skill mastery, some projectiles are easily "shot away" by recruits; when the pistol shooter pulls the trigger violently, the projectile deviates greatly and "hit the ground". According to statistics, the projectiles with the above situation account for about 8%-15%. When this situation occurs, the existing automatic target reporting system will default to "shooter did not shoot" because it cannot capture the "signal", which leads to missed reports and will inevitably cause the subsequent projectiles to report the hit order in a misplaced manner.

[0003] In addition, shooters often misjudge or miss targets due to nervousness. If there are more than two shooters shooting at the same target, the existing automatic target reporting system cannot distinguish them, resulting in "mixed reporting", which seriously affects the reporting information of other shooters (normal shooters) who have not missed the target. Without distinguishing the difference, when counting the scores of normal shooters, the current practice is to calculate the actual number of shots with higher rings on the target. This is obviously quite different from the actual hit (or miss) information, thus affecting the effectiveness of live-fire shooting training.

[0004] At the same time, the above situations such as "not reporting off-target, misplaced order, and not distinguishing wrong hits" not only affect the accuracy of the target reporting information, but also make it difficult to trace the actual shooting situation and ammunition consumption, which will affect the safe management and control of ammunition. Summary of the invention

[0005] In order to overcome the above-mentioned deficiencies in the prior art, the present invention provides an automatic target reporting system and method based on pressure sensing technology to solve at least one of the above-mentioned technical problems.

[0006] According to one aspect of the invention specification, there is provided an automatic target reporting system based on pressure sensing technology, comprising: a bullet firing information capturing module, a target hitting information capturing module and a mathematical computer; the bullet firing information capturing module is arranged at the rear of a gun stock and is close to the gun stock, and measures the recoil force generated by firing a supersonic flying projectile through a pressure sensor, obtains bullet firing information, and sends the bullet firing information to a mathematical computer; the target hitting information capturing module is used to capture target hitting information and send it to a mathematical computer; the mathematical computer is used to compare the received bullet firing information with the target hitting information, and to calculate shooting results according to the comparison results.

[0007] The above technical scheme is based on the existing automatic target reporting method and adds a module for obtaining projectile launch information. By capturing the projectile launch information and comparing it with the target hit information obtained by the existing system, accurate and reliable statistics of shooting results can be achieved, and the problems of false reporting, missed reporting and mixed reporting can be solved. The time, sequence, number of rings and other information of each bullet hitting and missing the target can be accurately obtained. In addition, when a shooter hits the wrong target, the actual shooting hit and miss information of two or more shooters can be identified through mathematical computer analysis.

[0008] The above technical solution can be applied to live-fire target reporting indoors or outdoors, and can be easily set up without replacing the original shooting range equipment, thereby realizing a training site compatible with different target reporting systems and avoiding excavation and line laying; at the same time, it improves the recognition defects of the existing target reporting system, enhances accuracy, and improves the safety and efficiency of military training.

[0009] Furthermore, the target hit information capture module includes a microprocessor for processing target surface information, thereby obtaining the hit time and number of targets, and sending them to a mathematical computer.

[0010] As a further technical solution, the system also includes an alarm module for sending an alarm instruction to remind the shooter after determining that the shooter has missed the target or has missed the target.

[0011] When the mathematical computer analysis shows that the current projectile has missed the target or hit the wrong target, an alarm command is sent to the alarm module wirelessly to promptly remind the shooter to re-identify the correct target.

[0012] Optionally, the alarm module includes an audible and visual alarm or a target position display terminal. The alarm module is wirelessly connected to the mathematical computer, receives instructions from the mathematical computer wirelessly, and promptly alarms and reminds the shooter on the target position.

[0013] As a further technical solution, the bullet firing information capturing module and the target hitting information capturing module both include a wireless transmitting module for wireless transmission with a mathematical computer.

[0014] As a further technical solution, the mathematical computer includes a data receiving module and a data processing module which are connected to each other, and the data receiving module is also connected to the wireless transmitting module.

[0015] Furthermore, the mathematical computer also includes a display screen.

[0016] As a further technical solution, the data processing module includes:

[0017] The first judgment module is used to judge whether the firearm has fired a bullet;

[0018] A recording module, used to record the launch time and impact time of the projectile when firing occurs;

[0019] The second judgment module is used to judge whether the launch time of the projectile is consistent with the hit time, and if it is judged to be consistent, it sends information to the projectile counting module; if it is judged to be inconsistent, it sends information to the retrieval module;

[0020] A retrieving module, used to retrieve other target hit information and send it to the third judgment module;

[0021] The third judgment module is used to judge whether the comparison of the projectile launch information is successful, and send information to the projectile counting module if the comparison is successful; if the comparison is unsuccessful, send an alarm reminder message to the shooter;

[0022] The projectile counting module is used to count the total shooting score and output it.

[0023] Furthermore, the difference between the launch time and the impact time is the projectile flight time. When the distance and the initial velocity of the projectile are constant, the time difference between the two is constant.

[0024] As a further technical solution, the data processing module also includes a fourth judgment module, which is used to judge whether to continue shooting when counting the number of normal hits of a projectile or obtaining an alarm reminder information.

[0025] As a further technical solution, the recoil force measured by the pressure sensor is the pressure sensed within a preset time after the trigger is pulled to fire the bullet. The pressure sensor is also connected to a battery.

[0026] The pressure sensor converts the force value into a related electrical signal, and may be composed of a force-sensitive element, a conversion element, and a circuit part.

[0027] The preset time is approximately 0.05 seconds, and refers to the time from when the bullet is fired to when the pressure sensor feels the recoil.

[0028] As a further technical solution, after capturing the pressure generated by the recoil force, the pressure sensor records the start and end time of the pressure, the pressure value and the pressure duration, and analyzes and obtains the bullet firing information based on the pressure.

[0029] According to one aspect of the present invention, there is provided an automatic target registration method based on pressure sensing technology, comprising:

[0030] Get the launch and hit information of the projectile;

[0031] When the projectile hit information is consistent with the projectile launch information in terms of quantity and time, the projectile is considered to have hit normally, and the number of the projectile rings is counted into the score;

[0032] When the number and time information of projectiles fired are generated, but the number and time information of projectiles hitting are not generated, the projectile is determined to be off-target;

[0033] Retrieving other target hit information and comparing it with the projectile launch information to determine whether it matches the target hit information of other shooters;

[0034] If the target hit information matches that of other shooters, the current shooter is judged to have hit the wrong target, and the projectile is counted into the score of the matching shooter. At the same time, an alarm is sounded to remind the shooter to re-identify the correct target.

[0035] As a further technical solution, the method further includes: numbering and storing each shooting target position and the target. According to the corresponding relationship between the shooting target position and the target, in the group coordinated shooting training, the same target is often shot multiple times by different shooters at different times. This method can accurately count the number of rings, number of shots, time and other information of each shooter hitting each target, thereby enhancing the effect of coordinated shooting training.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] (1) The present invention aims to improve the defects of the existing target reporting system. By adding a module to obtain projectile launch information and comparing the captured projectile launch information with the target hit information obtained by the existing system, the present invention can solve the problems of "no reporting of off-target, misplaced order, and no distinction of wrong hits" and at the same time realize accurate, true, automatic and reliable reporting of shooting results in shooting training.

[0038] (2) The present invention adopts a method of precise collaborative identification and analysis of sensors, which not only clearly presents the real shooting performance data to the shooter, but also accurately counts the ammunition consumption in terms of guns and bullets, providing an objective and real basis for the shooter to obtain accurate training results, adjust shooting status, and improve shooting training methods, thereby improving the quality and efficiency of light weapon shooting teaching and training.

[0039] (3) The present invention can accurately inform each shooter of the number of rings, number of shots, time and other information of each target hit by each shooter based on the matching of the target number and the shooter's target position, thereby enhancing the effect of coordinated shooting training and solving the problem that in the existing combat team coordinated shooting training, the same target is usually shot multiple times by different shooters at different times, but the target reporting system can only calculate the total number of hits of the combat team on the target.

[0045] The following will clearly and completely describe the technical solutions of various embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0046] The present invention solves the problems of false alarm, missed alarm and mixed alarm by adding a bullet firing information capture module at each target position on the basis of the existing automatic target reporting method, and accurately obtains the time, sequence, number of rings and other information of each bullet hitting and missing the target. In addition, when a shooter hits the wrong target, the actual shooting hit and miss information of two or more shooters can be identified through mathematical computer analysis.

[0047] like Figure 1-2As shown, an automatic target reporting system based on pressure sensing technology includes: a bullet firing information capturing module, a target hitting information capturing module and a mathematical computer; the bullet firing information capturing module is arranged at the rear of a gun stock and is close to the gun stock, and measures the recoil force generated by firing a supersonic flying projectile through a pressure sensor, obtains bullet firing information and sends the bullet firing information to a mathematical computer; the target hitting information capturing module is used to capture target hitting information and send it to a mathematical computer; the mathematical computer is used to compare the received bullet firing information with the target hitting information, and to count the shooting results according to the comparison results.

[0048] The bullet information capture module is composed of a pressure sensor, a battery and a wireless transmission module. The pressure sensor converts the force value into a related electrical signal and is composed of a force-sensitive element, a conversion element and a circuit part. The pressure sensor is set at the rear of the butt and is close to the butt. The pressure sensor can be set on the outer surface of the butt or inside the butt. Figure 3 As shown, the pressure sensor is arranged on the outer surface of the buttstock, which is equivalent to adding a layer of shoulder pad to the outer wall of the buttstock.

[0049] The caliber of the Type 95 automatic rifle is 5.8mm, the barrel is 463mm long, the initial velocity is 920m / s, and the gun weighs 3.3kg. After the bolt hits the primer of the bullet, the bullet shell is subjected to the pressure of the gunpowder gas, ignites the propellant, and generates gas through combustion, which expands rapidly, thereby pushing the projectile out and giving the projectile a high initial velocity. Pushing the bolt to recoil, the recoiled bolt hits the frame connected to / with the buttstock, thereby generating recoil, which is transmitted from the buttstock to the pressure sensor. This process takes about 0.05 seconds and directly acts on the front surface of the sensor, causing a slight deformation of the internal diaphragm. Because the thick film resistor is on the back of the ceramic diaphragm and is connected to it to form a Wheatstone bridge (closed bridge), due to the piezoresistive effect of the varistor, the bridge generates a highly linear voltage signal that is proportional to the pressure and proportional to the excitation voltage. Depending on the pressure range, the standard signal calibration is 2.0 / 3.0 / 3.3mV / V, etc., which is compatible with strain gauge sensors.

[0050] Through laser calibration, the sensor has high temperature stability and time stability. The sensor has built-in temperature compensation of 0℃~70℃ and can be in direct contact with most media. The resistance can make its operating temperature range as high as -40℃~135℃, and it has high precision and high stability of measurement. The electrical insulation degree is >2kV, the output signal is strong, and the long-term stability is good.

[0051] When the shooter is ready to shoot, a series of forces will be generated on the gun and himself, such as grip strength, cheek force, pressure on the trigger, shoulder force, etc. After the trigger is pulled, the bullet will feel the recoil in the 0.05 seconds from the time the recoil is felt. On the basis of the original data generated by the shoulder force on the pressure sensor, the pressure value of the recoil on the pressure sensor is suddenly increased, and the pressure duration is short and relatively fixed. By measuring the recoil generated by the launch of supersonic projectiles, after the pressure sensor receives the pressure signal, combined with the pressure data, such as the start and end time of the pressure, the pressure value and the duration of the pressure, the number of bullets fired, the launch time and other information can be analyzed and obtained, and then the data information is sent to the mathematical computer through the wireless transmission module.

[0052] The target hit information capturing module is implemented by using the existing automatic target reporting system, and the module is wirelessly connected to a mathematical computer.

[0053] The mathematical computer comprises a data receiving module, a data processing module and a display screen.

[0054] like Figure 4 As shown, the data processing module includes: a first judgment module, used to judge whether the projectile is fired; a recording module, used to record the launch time and hit time of the projectile when firing; a second judgment module, used to judge whether the launch time and hit time of the projectile are consistent, and when it is judged to be consistent, send information to the projectile counting module, and when it is judged to be inconsistent, send information to the retrieval module; the retrieval module is used to retrieve other target hit information and send it to the third judgment module; the third judgment module is used to judge whether the projectile launch information is successfully compared, and when the comparison is successful, send information to the projectile counting module, and when the comparison is unsuccessful, send an alarm reminder message to the shooter; the projectile counting module is used to count the total shooting score and output it.

[0055] Furthermore, the difference between the launch time and the impact time is the projectile flight time. When the distance and the initial velocity of the projectile are constant, the time difference between the two is constant.

[0056] The data processing module also includes a fourth judgment module, which is used to judge whether to continue shooting when counting the number of normal hits of a projectile or obtaining an alarm reminder information.

[0057] The system also includes an alarm module, which includes an audible and visual alarm or a target position display terminal. The alarm module is wirelessly connected to the mathematical computer, receives instructions from the mathematical computer in a wireless manner, and promptly alarms and reminds the shooter on the target position.

[0058] like Figure 5 As shown, an automatic target reporting method based on pressure sensing technology includes:

[0059] Get the launch and hit information of the projectile;

[0060] When the projectile hit information and the projectile launch information are consistent in number and time, the projectile is considered to have hit normally, and the number of the projectile rings is counted into the score;

[0061] When the number and time information of projectiles fired are generated, but the number and time information of projectiles hitting are not generated, the projectile is determined to be off-target;

[0062] Retrieving other target hit information and comparing it with the projectile launch information to determine whether it matches the target hit information of other shooters;

[0063] If the target hit information matches that of other shooters, the current shooter is judged to have hit the wrong target, and the projectile is counted into the score of the matching shooter. At the same time, an alarm is sounded to remind the shooter to re-identify the correct target.

[0064] The method further includes: numbering and storing each shooting target position and the target accordingly. According to the corresponding relationship between the shooting target position and the target, in the group coordinated shooting training, the same target is often shot multiple times by different shooters at different times, and the number of rings, number of shots, time and other information of each shooter hitting each target can be accurately counted, thereby enhancing the effect of coordinated shooting training.

[0065] As an implementation method, an application is used when a shooter hits the wrong target during live-fire shooting. When the projectile hit information and the projectile launch information match in quantity and time (the difference between the launch time and the hit time is the projectile flight time, and the time difference between the two is constant when the distance and the initial velocity of the projectile are constant), the projectile is determined to have hit normally; when the projectile launch quantity and time information is generated, but the hit quantity and time information is not generated, it means that the projectile fired by the shooter (A) is off target, and the mathematical computer retrieves the hit information of other targets and compares it with the projectile launch information. If it matches the target hit information of shooter (B), it means that the shooter (A) hit the wrong target and hit the target of shooter (B). The mathematical computer automatically counts the projectile into the score of shooter (A), and sends a command to the alarm through wired or wireless means to immediately remind the shooter to re-identify the correct target.

[0066] As an implementation method, an application is provided when a shooter misses a target and fails to hit the effective reporting area of ​​the target during live ammunition shooting (i.e., "misses"). Shooter (A) shoots 5 bullets, and the 1st, 2nd, 4th, and 5th bullets hit the target normally, but the 3rd bullet "misses" and misses the target. At this time, the launch information subsystem will obtain the launch data and transmit it to the mathematical computer. The mathematical computer verifies the target (surface) reporting data. When no hit (or miss) information is obtained, it is determined that the shooter (A) missed the target or hit the wrong target. The mathematical computer follows the implementation method steps of "Specific Example 1" to exclude the possibility that the shooter (A) hits the wrong target, and finally determines that the shooter's 3rd bullet is "missed". This example effectively avoids the existing automatic target reporting system from "silent" in the above situation because it fails to capture the hit data. When the subsequent fourth bullet hits normally, the score of the fourth bullet is mistakenly recorded as the score of the third bullet, and the score of the fifth bullet is recorded as the score of the fourth bullet. It cannot accurately report which of the five bullets shot by the shooter (A) missed the target, resulting in the third bullet missing the target and the wrong order of the hits of the next two bullets, which in turn affects the shooter (A)'s review of the shooting results. In addition, during the live-fire shooting process, if the shooter observes the hit information on the target reporting system after shooting one bullet, it will greatly distract the shooter's attention and affect the shooter's psychology. This is not a good shooting habit.

[0067] As an implementation method, during the coordinated shooting training of the combat team, multiple shooters shoot at multiple recurring hidden and visible targets. For example, there are 3 shooters numbered X1, X2, and X3, and 6 targets numbered Y1, Y2, Y3, Y4, Y5, and Y6. When the same target is shot multiple times by different shooters at different times, the existing target reporting system can only calculate the total number of hits of the combat team on the target. By using the method of the present invention, according to the target number and the shooter target position number, the number of rings, the number of shots, the time and other information of each shooter hitting each target can be accurately reported. The system can calculate and judge the intensity of the target (target) being killed based on the number of hit rings. For example, if the target Y5 is damaged, and the shooter X2 hits Y5 for the first time with 7 rings, it can be determined that the target Y5 is slightly injured; the target Y5 still has combat capability and can be shown again. When the shooter X1 hits 10 rings for the second time, it can be determined that the target Y5 is eliminated and no longer shown. Therefore, the present invention can effectively enhance the benefits of collaborative shooting training, and by utilizing the automatic target reporting method in collaborative shooting training, accurate analysis can be achieved and actual hit situations can be restored.

[0068] As an embodiment, the "projectile launch time" (t 发射 ) refers to the time after the projectile is fired from the muzzle at high speed under the action of gunpowder gas and detected by the shock wave sensor, and the "projectile impact time" (t 命中 ) refers to the time when the projectile contacts the target (surface) and is detected by the automatic target reporting system. The difference between the time when the projectile (projectile) hits the target and the time when the projectile is launched (t), t = t命中 -t 发射

[0069] It is mainly determined by the distance between the gun and the target, the speed of the bullet, wind resistance, shock wave sensor capture time, target reporting reaction time and data processing time. Among them, wind resistance is a variable factor, so the t value is not a constant value. Since the wind resistance is the same at the same time, when the mathematical computer needs to compare the data of "possible misses", the t value can be calculated based on the t values ​​of other target positions in the same round of shooting to calculate the "possible miss" projectile hit time (t 命中 ). For example, 10 shooters are respectively located at 10 shooting positions, numbered X1, X2, X3 ... X10, corresponding to 10 targets Y1, Y2, Y3 ... Y10, respectively. When shooters X2 and X5 each miss the target with one shot (the target has no target reporting data), the mathematical computer calculates the time when the projectile shot by shooter X2 hits the target based on the average value of the t values ​​of the remaining 9 shooting positions. If there is no hit information in the measured time, it is determined that the projectile shot by shooter X2 is a miss; further, the mathematical computer determines whether shooter X2 hits the wrong target according to the implementation method steps of "Example 1".

[0070] As an implementation mode, the time data acquisition of the present invention is precisely recorded as t 精确度 seconds. When two shooters fire at the same time, one misses the target and the other misses the target. According to a large number of sample data statistics, when the number of bullets fired at a fixed target is n, according to the outline requirements, the total shooting time is t 总 , let the time taken by the shooter to shoot the i-th projectile be t i (i=1,2,…,n), then:

[0071]

[0072] Furthermore, the average off-target rate was The average miss rate is The probability P of the above situation occurring is:

[0073]

[0074] When shooting at a hidden or visible target, let the target display time be t 显示 seconds, using n1 bullets, and firing n2 rounds each time. When there are N shooters participating in the shooting, the probability of the above situation occurring is P 隐显 for:

[0075]

[0076] Therefore, when the time data in the present invention is collected accurately to 0.01 seconds, the probability analysis of two shooters firing at the same time, one of them misses the target and the other misses the target is as follows: According to a large number of sample data statistics, when firing 5 rounds at a fixed target, it is assumed that the total time used by the shooter after 5 shots is 126 seconds, that is:

[0077]

[0078] The average miss rate is 0.017, and the average miss rate is 0.0035. When there are 10 shooters participating in the shooting, the probability of the above situations occurring is:

[0079]

[0080] In the hidden target shooting, the target display time is 6 seconds, 10 rounds are used, and 2 rounds are fired each time. When there are 10 shooters participating in the shooting, the probability of the above situation is:

[0081]

[0082] From this we can see that it is still highly operational in specific instances.
