Description

Technical Field

[0001] This invention relates to the field of military training equipment, specifically to an automatic target reporting system and method based on linear Hall effect technology. Background Technology

[0002] In live-fire training, instances of projectiles missing the target (target surface) occur frequently. For example, new recruits, due to psychological factors or poor skill mastery, are prone to missing some projectiles; pistol shooters may pull the trigger too hard, causing the projectile to deviate significantly and hit the ground. Statistics show that these situations occur in approximately 8%-15% of shots. When this happens, the existing automatic target reporting system, failing to detect the "signal," defaults to "shooter not firing," leading to missed reports and inevitably causing misreporting of subsequent projectile hits. Furthermore, shooters sometimes misread or fire at the wrong target due to nervousness. If two or more shooters fire at the same target, the existing automatic target reporting system cannot distinguish between them, resulting in mixed reports that severely impact the target reporting information of other shooters who did not miss the target (normal shooters). Without this distinction, the current practice for calculating the scores of normal shooters is to use the higher ring number on the target. This clearly deviates significantly from the actual hit (or miss) information, affecting the effectiveness of live-fire training. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides an automatic target reporting system and method based on linear Hall effect technology to solve at least one of the above-mentioned technical problems.

[0004] According to one aspect of the present invention, an automatic target reporting system based on linear Hall effect technology is provided, comprising:

[0005] A linear Hall sensor, mounted on the rifle body, is used to acquire projectile information from the rifle; the projectile information includes whether a projectile was fired and the time of firing.

[0006] A target surface information acquisition module is disposed on the target and is used to sense the target surface information of the target; the target surface information includes the number of rings hit and the hit time.

[0007] The mathematical computer is wirelessly connected to a linear Hall sensor and a target information acquisition module. The mathematical computer includes a data receiving module for receiving sensing data from the linear Hall sensor and target information. It also includes a data processing module for generating shooting performance information based on projectile information and target information. Finally, the mathematical computer includes a data sending module for sending the shooting performance information to the shooter.

[0008] In the above technical solution, when the shooter fires a bullet, a linear Hall sensor mounted on the rifle senses the projectile information, which includes the bullet's firing time. This information is transmitted to a mathematical computer. When the bullet hits the target, the target information acquisition module acquires the target information and transmits it to the mathematical computer. The mathematical computer pre-stores the distance between the shooter and the target and the bullet's velocity. Based on these parameters, the computer calculates the bullet's flight time. When the sum of the bullet's firing time and its flight time matches the bullet's hit time, the hit score obtained by the target information acquisition module is the shooter's score. The mathematical computer generates the shooting score information based on the hit score and sends it to the shooter. The shooter is then informed of their score via a display device or voice device. This automatic target reporting system verifies whether the shooter's bullet firing and the target hit belong to the same shot, thus avoiding misreporting or omissions in the shooting score.

[0009] Furthermore, the mathematical computer also includes an early warning module, which generates early warning information when the shooter misses the target, and the early warning information is sent to the shooter through a data transmission module.

[0010] When the shooter misses the target, the warning module generates a warning message to remind the shooter to adjust the shooting angle or re-identify the target, thereby improving the training effect of shooting training.

[0011] Furthermore, the linear Hall sensor includes a strong magnetic magnet and a Hall element, the strong magnetic magnet being disposed in the bolt handle hole of the rifle bolt, and the Hall element being disposed on the carrying handle of the rifle handguard.

[0012] When a rifle is fired, the bolt handle reciprocates during the firing process, and the speed of this reciprocating motion is significantly greater than the speed when the bolt handle is manually pulled. The Hall element senses the distance and time of the reciprocating motion of the strong magnetic magnet and transmits this distance and time to the connected microprocessor. The microprocessor calculates the speed of the bolt handle based on the received data. When the speed of the bolt handle exceeds a certain threshold, it indicates that the rifle has completed a bullet firing. At the same time, the time when the bolt handle begins to move is obtained as the bullet firing time, and then the projectile information is generated and sent to the mathematical computer.

[0013] Furthermore, the automatic target reporting system also includes a shock wave capture device located below the front side of the target. The shock wave capture device is used to capture the position information of the bullet before it hits the target and transmit the position information to a mathematical computer.

[0014] The shock wave capturing device forms a shock wave capturing surface in front of the target, with the target's center as the center, and the area covered by the shock wave capturing surface is larger than the target's surface area. When the bullet misses the target, the device acquires the position information of the bullet passing through the shock wave capturing surface, thereby determining the direction from which the bullet missed the target and the distance from the target at the time of miss.

[0015] Furthermore, the mathematical computer is also used to generate miss information based on the position information when no target information is received, and to transmit the miss information to the shooter.

[0016] When the mathematical computer receives projectile information indicating that the shooter has fired a bullet, but the target has not acquired target surface information (i.e., the shot missed the target), and there is no extra target surface information on the non-target (i.e., the shot missed the non-target), it means that the shooter's shot missed the target. At this time, the position information captured by the shock wave capture device is obtained to determine the azimuth and distance from the target center when the automatic miss occurs. Based on this azimuth and distance, a miss information is generated and sent to the shooter, informing the shooter of the azimuth and distance of the miss, so that the shooter can accurately and timely adjust the shooting angle and state, thereby improving shooting training performance and training effect.

[0017] According to another aspect of the present invention, an automatic target reporting method is provided, comprising the following steps:

[0018] S1: Obtain projectile information and determine whether to fire the bullet based on the projectile information. If so, obtain the bullet firing time and proceed to S2.

[0019] S2: Determine whether the data receiving module has received the target surface information of the target. If so, proceed to S3.

[0020] S3: Obtain the straight-line distance between the shooter and the target and the bullet's velocity, and calculate the bullet's first flight time; calculate the theoretical hit time based on the bullet's first flight time and the bullet's firing time;

[0021] S4: Determine whether the theoretical target time and the hit time of the target match. If so, generate the first shooting score based on the number of rings hit by the target and send the first shooting score to the shooter.

[0022] In the above technical solution, by judging whether the theoretical target time and the actual hit time match, it is determined whether the shooter's shot corresponds to the hit on the target, thereby avoiding the mismatch between the shooter's shot and the hit on the target, thus preventing false or missed reports in the target reporting.

[0023] Further, in step S2, if the data receiving module does not receive the target surface information, the following steps are performed:

[0024] S3-1: Obtain the target surface information of non-target targets around the target target, and determine whether there is redundant target surface information on the non-target targets. If so, proceed to step S3-2.

[0025] S3-2: Obtain the straight-line distance between the shooter and the non-target and the bullet's flight speed, and calculate the bullet's second flight time. Based on the bullet's second flight time and the bullet's firing time, calculate the theoretical time for the bullet to hit the non-target.

[0026] S3-3: Determine whether the hit time in the redundant target information on the non-target target matches the theoretical time for the bullet to hit the non-target target. If so, it means that the shooter hit the non-target target. Generate a second shooting score based on the hit ring number in the redundant target information on the non-target target and send the second shooting score to the shooter.

[0027] When shooter A's projectile information is obtained, but the corresponding target surface information on the target is not, it indicates that shooter A may have missed the target or hit a non-target target. In this case, the target surface information on the non-target target is first obtained. It is then determined whether there is redundant target surface information. Specifically, the projectile information of shooter B corresponding to the non-target target is paired with the target surface information of that non-target target. If the target surface information of the non-target target contains corresponding projectile information of shooter B, it means that the shot corresponding to that target surface information was completed by shooter B. If the target surface information of the non-target target contains target surface information that does not correspond to shooter B's projectile information, it means that the bullet corresponding to that target surface information was not fired by shooter B. Then, the redundant target surface information is paired with shooter A's projectile information. If the pairing is successful, it means that shooter A fired the bullet onto the target corresponding to shooter B (i.e., the non-target target). The hit score on the non-target target is recorded as shooter A's shooting score and sent to shooter A.

[0028] Furthermore, step S3-3 also includes: generating warning information and sending the warning information to the shooter, wherein the warning information is used to remind the shooter that a non-target has been hit and the location information of the non-target hit by the shooter.

[0029] If shooter A hits a non-target, a warning message is generated. The warning message includes the location of the non-target and / or the approximate location of the impact point. For example, the warning message may be the following text or voice content: "Shooter hits a non-target. The non-target is located to the left of the target. Please re-identify the target and continue shooting training."

[0030] Furthermore, in step S3-1, if there is no extra target surface information on the non-target, then proceed to the following step:

[0031] The system acquires position information captured by the shock wave capture device, generates miss information based on the position information, and sends the miss information to the shooter; the miss information includes the distance and relative direction between the bullet and the target bullseye.

[0032] When there is no target surface information corresponding to shooter A's projectile information on either the target or non-target surfaces, it indicates that shooter A's shot missed the target. In this case, the mathematical computer obtains the position information captured by the shock wave from the shock wave capture device, thereby determining the direction and distance of the bullet from the target when it missed. The warning module generates a miss information message and sends it to the shooter via the data transmission module. For example, the miss information could be: "Shooter's shot missed the target; the bullet missed the target at 30cm from the 2 o'clock position." Based on this miss information, the shooter knows the direction and distance of the miss, allowing them to adjust their shooting direction and gun-holding posture for the next shot, thus improving their shooting training performance.

[0033] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0034] (1) The present invention provides an automatic target reporting system based on linear Hall effect technology. When the shooter fires a bullet, a linear Hall effect sensor installed on the rifle senses the bullet information, which includes the bullet firing time. This bullet information is transmitted to a mathematical computer. When the bullet hits the target, the target information acquisition module acquires the target information and transmits it to the mathematical computer. The mathematical computer pre-stores the distance between the shooter and the target and the bullet's flight speed. The mathematical computer calculates the bullet's flight time based on the distance between the shooter and the target and the bullet's flight speed. When the sum of the bullet firing time and the bullet's flight time matches the bullet's hit time, it indicates that the hit score acquired by the target information acquisition module is the shooter's shooting score. The mathematical computer generates shooting score information based on the hit score and sends it to the shooter. The shooter is informed of their shooting score through a display device or a voice device. This automatic target reporting system verifies whether the shooter's bullet firing and the bullet hit on the target belong to the same shot, thereby avoiding misreporting or omission of shooting scores.

[0035] (2) The present invention provides an automatic target reporting method, which determines whether the theoretical target time and the actual hit time match, and whether the shooter's shot corresponds to the hit on the target surface, thereby avoiding the incorrect pairing of the shooter's shot with the hit on the target surface, and thus preventing false or missed reports in target reporting.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0044] Example 1

[0045] like Figure 1 As shown, this embodiment provides an automatic target reporting system based on linear Hall effect technology, including:

[0046] A linear Hall sensor, mounted on the rifle body, is used to acquire projectile information from the rifle; the projectile information includes whether a projectile was fired and the time of firing.

[0047] Specifically, the linear Hall sensor includes a cylindrical strong magnetic magnet and a Hall element. The strong magnetic magnet is disposed inside the bolt handle hole of the rifle, and the Hall element is disposed on the carrying handle of the rifle handguard (e.g., Figure 2 (As shown). In this embodiment, the rifle is also equipped with a microprocessor, which is connected to a Hall element. The microprocessor receives the sensing data from the Hall element and calculates the movement speed of the trigger handle based on the sensing data. When the movement speed of the trigger handle is greater than a threshold, it indicates that the movement of the trigger handle is caused by the firing of a bullet, and it is recorded as the firing of a bullet. At the same time, the time when the trigger handle starts to move is obtained as the bullet firing time, and the projectile information is further generated and sent to the mathematical computer.

[0048] The rifle is also equipped with a storage battery to power the Hall element and the microprocessor; the rifle is also equipped with a first data transmission module, which is connected to the storage battery and the microprocessor, and is also communicatively connected to the data receiving module of the mathematical computer.

[0049] When an automatic rifle fires a supersonic projectile, the bolt handle and the automatic mechanism move at high speed. During this high-speed motion, the magnetic field generated by the strong magnet constantly changes displacement. In this reciprocating motion, the magnetic flux density in the Hall element undergoes periodic and significant changes, which are converted into regularly varying electrical signals. (The working principle of a linear Hall sensor is as follows...) Figure 3 (As shown)

[0050] Taking the Type 95-1 automatic rifle as an example, its single-shot combat rate of fire is 40 rounds / minute, and its theoretical rate of fire in bursts is 650 rounds / minute, with a combat rate of fire of 100 rounds / minute. During firing, the bolt displacement distance of the Type 95 and Type 95-1 automatic rifles is 11.5 centimeters. Because the speed, frequency, and force of manually pulling the bolt are much lower than the autonomous movement of the rifle during single-shot or burst fire, the difference between manual pulling and the autonomous movement of the bolt handle can be distinguished through analysis and processing of the electrical signals. When the movement speed of the bolt handle matches the movement data during bullet firing, it is counted as firing one round.

[0051] The single-shot combat rate of fire is 40 rounds / minute; in burst fire, the theoretical rate of fire is 650 rounds / minute, and the combat rate of fire is 100 rounds / minute, with a single-stroke displacement of 0.115 meters for the bolt handle. Since the bolt drives the bolt handle in one reciprocating motion to chamber the next round, the bolt's motion pattern and instantaneous rate remain consistent in both single-shot and burst fire. Therefore, when firing one round, the bolt handle's reciprocating motion time should be less than 1 / 650 = 0.001538 minutes, approximately 0.092307 seconds. That is, the bolt handle's reciprocating motion time satisfies the following:

[0052]

[0053] When the distance x is approximately 0.23 meters in this time, the minimum average instantaneous speed of the handle is approximately:

[0054]

[0055] The rate at which the shooter manually completes the bolt-action and bolt-pushing process is approximately 0.307-0.575 m / s, and the maximum average instantaneous speed of the bolt handle movement is approximately:

[0056]

[0057] As can be seen from the above, the speed of the trigger handle when the shooter manually pulls it is much lower than the speed of the trigger handle when firing. Therefore, a threshold can be taken between the two. When the speed of the trigger handle is greater than the threshold, it means that a bullet has been fired.

[0058] Preferably, the linear Hall sensor in this embodiment is an ASIC-type linear Hall sensor. The ASIC-type linear Hall sensor has a stable circuit structure and can eliminate the offset voltage of the Hall element. By combining the circuit module and operational amplifier, the offset voltage and magnetic field voltage are separated in the frequency domain. The DC offset is modulated into a high-frequency signal, which is then filtered out by the subsequent low-pass filter circuit, resulting in a precise output magnetic field voltage. This achieves higher sensing accuracy, and simulation verification shows that the offset voltage is eliminated by 90%.

[0059] The ASIC-type linear Hall sensor enables dynamic sensitivity adjustment. Users can program the chip via the VCC and VOUT pins, interact with the highly integrated EEPROM, and store calibration values. The internal digital circuitry calculates these values ​​to generate corresponding adjustment signals, enabling dynamic configuration of sensitivity and quiescent voltage. The sensitivity adjustment range is 0.6–14.8 mV / G, with the initial quiescent voltage set at half the power supply voltage; a typical adjustment range is 2–3 V.

[0060] The ASIC-type linear Hall sensor features a digitally compensated system architecture, improving its temperature-dependent sensitivity. When the operating temperature changes, the internal processor calculates the correlation coefficients stored in the EEPROM according to the temperature compensation formula, generating a compensation signal to alter the operational amplifier gain in the analog signal path, thereby compensating for the temperature drift of the Hall element's sensitivity. Test results show that within the range of -40℃ to 150℃, the Hall sensor's sensitivity temperature drift is controlled within +3%, and when the sensitivity is less than 85mV / G, linearity with an error within 1% can be guaranteed.

[0061] The automatic target reporting system also includes a target surface information acquisition module, which is installed on the target and used to sense the target surface information; the target surface information includes the number of rings hit and the hit time.

[0062] The automatic target reporting system also includes a mathematical computer, which is wirelessly connected to a linear Hall sensor and a target surface information acquisition module. The mathematical computer includes a data receiving module for receiving sensing data from the linear Hall sensor and target surface information. The mathematical computer also includes a data processing module for generating shooting score information based on projectile information and target surface information. The mathematical computer also includes a data sending module for sending the shooting score information to the shooter.

[0063] The shooter's end is equipped with a display device or a voice broadcasting device. The display device and the voice broadcasting device are used to receive shooting results information sent by the data transmission module, warning information generated by the warning module, and miss information, and to convey the above information to the shooter in text or voice form.

[0064] In a preferred embodiment, the mathematical computer also includes an early warning module. This module generates an early warning message when the shooter hits a non-target, and the message is transmitted to the shooter via a data transmission module. When the shooter hits a non-target, the early warning module generates a warning message to remind the shooter to adjust the firing angle, thereby improving the training effect of shooting practice. For example, the warning message may include the following: "Shot hit a non-target. Please reconfirm the target's position before continuing to fire."

[0065] In a preferred embodiment, the automatic target reporting system further includes a shock wave capture device disposed below the front side of the target. The shock wave capture device is used to capture the position information of the bullet before it hits the target and transmit the position information to a mathematical computer.

[0066] The shock wave capturing device forms a shock wave capturing surface in front of the target, centered on the target's center. The area covered by this surface is larger than the target's surface area, and the surface is parallel to the target's surface. When the bullet misses the target, the device acquires information about its position after passing through the shock wave capturing surface, thus determining the bullet's departure point and distance from the target. The horizontal distance between the shock wave capturing surface and the target surface is less than 10 cm, reducing errors in determining the bullet's position and distance from the target.

[0067] Preferably, the mathematical computer is further configured to generate miss information based on the position information when the shooter misses the target, and transmit the miss information to the shooter.

[0068] When the mathematical computer receives projectile information indicating that the shooter has fired a bullet, but the target has not acquired target surface information (i.e., the shot missed the target), and there is no extra target surface information on the non-target (i.e., the shot missed the non-target), it means that the shooter's shot missed the target. At this time, the position information captured by the shock wave capture device is obtained to determine the azimuth and distance from the target center when the automatic miss occurs. Based on this azimuth and distance, a miss information is generated and sent to the shooter, informing the shooter of the azimuth and distance of the miss. This allows the shooter to purposefully and accurately adjust the shooting angle, thereby improving shooting training performance and training effectiveness.

[0069] Example 2

[0070] like Figure 4 As shown, this embodiment provides an automatic target reporting method. Assume that shooter A and shooter B are conducting shooting training in adjacent positions on a training field, and shooter A's target is target T. a Shooter B's target is target T. b Target T b If shooter A is considered a non-target, then the target reporting method for shooter A includes the following steps:

[0071] S1: Obtain shooter A's projectile information M a And based on the projectile information M a Determine whether shooter A has fired a bullet. If so, determine from the bullet firing information M... a After obtaining the bullet firing time t1 of shooter A, proceed to S2; otherwise, it means that shooter A did not fire a bullet and there is no need to report the target.

[0072] S2: Determine whether the data receiving module of the mathematical computer has received the target T. a If the target information is correct, it means that the bullet fired by shooter A hit the target T. a If yes, proceed to S3; otherwise, it means that the bullet fired by shooter A did not hit the target T. a At this point, there are two possibilities: either the bullet fired by shooter A hits the target T, or... b (This usually occurs when shooter A mistakenly targets the target T) b (If the target is identified as their own, the second is that the bullet fired by shooter A misses the target;)

[0073] S3: Acquire Shooter A and Target T a The straight-line distance between the bullet and the target (which has been pre-input into the mathematical computer) and the bullet velocity (the bullet velocity is determined according to the rifle type and pre-stored in the mathematical computer) are calculated, and the first flight time of the bullet fired by shooter A is calculated; the theoretical hit time is calculated based on the first flight time and the bullet firing time.

[0074] Specifically, the method for calculating the first flight time of a bullet is as follows:

[0075]

[0076] Where t2 is the first flight time of the bullet, L Aa For shooter A to target T a The straight-line distance between them, where v is the bullet's velocity.

[0077] The theoretical method for calculating target time is as follows:

[0078] t3 = t1 + t2

[0079] S4: Determine the theoretical target time t3 and the target T. a Check if the hit time in the target information matches. If it does, it means that the bullet fired by shooter A hit the target T. a If the bullets corresponding to the target information are the same bullets, then the first shooting score is generated based on the number of hit rings in the target information of shooter A's target, and the first shooting score is sent to the shooter.

[0080] Furthermore, such as Figure 5 As shown, in step S2, the bullet fired by shooter A misses the target T. a Then proceed to the following steps:

[0081] S3-1: Obtain the target (target T) for shooter A a The surrounding non-target targets (target T) b ) target surface information, to determine target T b If there is any redundant target surface information, proceed to step S3-2.

[0082] S3-2: Acquire Shooter A and Target T b The straight-line distance between the target and the target (which is pre-stored in a mathematical computer) and the bullet's velocity are calculated, along with the bullet's second flight time. Based on this second flight time and the bullet's firing time, the theoretical time for the bullet to hit the non-target target (i.e., the time T when the bullet fired by shooter A hits the target) is calculated. b (time);

[0083] Specifically, the second flight time of the bullet is calculated as follows:

[0084]

[0085] In the formula: t4 is the second flight time of the bullet, L Ab For shooter A, the distance to target T is... b The straight-line distance.

[0086] The theoretical time t5 for a bullet to hit a non-target is calculated as follows:

[0087] t5 = t1 + t4

[0088] S3-3: Determine the target T b Does the hit time in the redundant target information match the theoretical time t5 for the bullet to hit the non-target target? If so, it means that shooter A hit the target T. b Target T b The number of hits in the extra target information is used as shooter A's shooting score, and a second shooting score is generated and sent to shooter A.

[0089] Furthermore, such as Figure 6 As shown, in step S3-1, the target T b If there is no additional target information above, it means that the bullet fired by shooter A hit the target T. a or target T b If this is the case, it can be assumed that the bullet fired by shooter A missed the target, and the target T is then obtained. a The shock wave capturing device on the lower front side captures the position information of the bullet as it passes through the shock wave capturing surface, and calculates the distance between the bullet fired by shooter A and the target T when it misses the target based on the position information. a The relative direction and distance to the bullseye are used to generate miss information, which is then sent to shooter A.

[0090] Furthermore, if the shock wave detection device fails to detect the bullet passing through, it indicates that the bullet fired by shooter A was at a distance of 0.5 meters from the target T. a If the distance is too large, a first miss message is generated and sent to shooter A. For example, the first miss message may include the following: "The bullet missed the target and the distance to the target is too large. Please adjust the shooting angle and continue shooting."

[0091] Furthermore, when the shock wave capture device detects the bullet passing through, in addition to generating position information and transmitting it to the mathematical computer, it also needs to obtain the time t6 when the bullet passes through the shock wave capture surface.

[0092] Simultaneously, based on the straight-line distance between shooter A and the corresponding shock wave capturing surface (this straight-line distance is pre-stored in the mathematical computer) and the bullet's flight velocity, the third flight time of the bullet fired by shooter A to the shock wave capturing surface is calculated. Then, based on the third flight time and the bullet's firing time, the theoretical time t7 for passing through the shock wave capturing surface is calculated. It is then determined whether t6 and t7 match. If they do, it indicates that the bullet captured by the shock wave capturing device is the bullet fired by shooter A. After generating the second miss information, it is sent to shooter A. At this time, the second miss information can be: "Bullet misses target, distance T from target". a"30cm from the two o'clock position of the bullseye"; if not, it means that the bullet captured by the shock wave capture device was fired by shooter B, and the second miss information is generated and sent to shooter B.

[0093] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the technical solutions of the embodiments of the present invention.

When the bullet misses the target, the system acquires the position information of the bullet passing through the shock wave capturing surface and transmits the position information to a mathematical computer. The mathematical computer acquires the position information captured by the shock wave capturing device, determines the orientation and distance from the target center when the bullet automatically misses the target, and generates a miss information based on the orientation and distance and sends it to the shooter.

2. The automatic target reporting system based on linear Hall effect technology according to claim 1, characterized in that, The mathematical computer also includes an early warning module, which generates early warning information when the shooter misses the target. The early warning information is sent to the shooter through a data transmission module.

3. The automatic target reporting system based on linear Hall effect technology according to claim 1, characterized in that, The linear Hall sensor includes a strong magnetic magnet and a Hall element. The strong magnetic magnet is disposed in the bolt handle hole of the rifle bolt, and the Hall element is disposed on the carrying handle of the rifle handguard.

4. An automatic target reporting method, comprising an automatic target reporting system based on linear Hall effect technology as described in any one of claims 1-3, characterized in that, Includes the following steps: S1: Obtain projectile information and determine whether to fire the bullet based on the projectile information. If so, obtain the bullet firing time and proceed to S2. S2: Determine whether the data receiving module has received the target surface information of the target. If so, proceed to S3. S3: Obtain the straight-line distance between the shooter and the target and the bullet's velocity, and calculate the bullet's first flight time; calculate the theoretical hit time based on the bullet's first flight time and the bullet's firing time; S4: Determine whether the theoretical target time and the hit time of the target match. If so, generate the first shooting score based on the number of rings hit by the target and send the first shooting score to the shooter.

5. The automatic target reporting method according to claim 4, characterized in that, If, in step S2, the data receiving module does not receive the target surface information, then the following steps are performed: S3-1: Obtain the target surface information of non-target targets around the target target, and determine whether there is redundant target surface information on the non-target targets. If so, proceed to step S3-2. S3-2: Obtain the straight-line distance between the shooter and the non-target and the bullet's flight speed, and calculate the bullet's second flight time. Based on the bullet's second flight time and the bullet's firing time, calculate the theoretical time for the bullet to hit the non-target. S3-3: Determine whether the hit time in the redundant target information on the non-target target matches the theoretical time for the bullet to hit the non-target target. If so, it means that the shooter hit the non-target target. Generate a second shooting score based on the hit ring number in the redundant target information on the non-target target and send the second shooting score to the shooter.

6. The automatic target reporting method according to claim 5, characterized in that, Step S3-3 further includes: generating warning information and sending the warning information to the shooter. The warning information is used to remind the shooter that a non-target has been hit and the location information of the non-target hit by the shooter.

7. The automatic target reporting method according to claim 5, characterized in that, In step S3-1, if there is no extra target surface information on the non-target target, then proceed to the following steps: The system acquires position information captured by the shock wave capture device, generates miss information based on the position information, and sends the miss information to the shooter; the miss information includes the distance and relative direction between the bullet and the target bullseye.
