Description

Technical Field

[0001] This application relates to the field of military equipment and training technology, and in particular to a danger warning device and warning method for shooting training. Background Technology

[0002] Shooting skills are essential for military personnel. Through proper training, military personnel can maintain or even improve their shooting abilities, thereby enhancing the overall military capability of the nation.

[0003] Currently, shooting training mostly employs simulated or live-fire methods. In live-fire training, two or more teams are often arranged for adversarial training, depending on the training objectives, to adapt to the needs of a real battlefield. In this type of training, because the weapons use live or near-live ammunition, it poses a certain threat to the personal safety of the trainees. To mitigate this threat, existing technologies offer various solutions. For example, CN115523794A discloses a dangerous shooting pointing warning device and a dangerous shooting alarm system. This patent uses light signal transmission and reception to determine whether there are personnel directly in front of the weapon. If so, it locks the weapon's trigger to prevent accidental operation and potential casualties.

[0004] However, the aforementioned patent uses optical signals for personnel detection. In training grounds, obstacles can easily block the optical signal, preventing the weapon's trigger from locking. Furthermore, not all obstacles can completely stop bullets; bullets can still penetrate thin obstacles, such as foliage, exposing personnel to danger if they are behind such obstacles. Summary of the Invention

[0005] This application provides a danger warning device and method for shooting training, which solves the problem that the use of optical signals for personnel detection in the prior art can easily lead to personal threats to trainees due to being misled by obstacles.

[0006] On one hand, embodiments of this application provide a danger warning device for shooting training, including:

[0007] The data processing unit is used to determine whether there are trainees directly in front of the firing unit;

[0008] A signal transmitting unit is installed on the firing unit. The signal transmitting unit is used to transmit radio electromagnetic wave signals to the front of the firing unit when the data processing unit determines that there are trainees directly in front of the firing unit.

[0009] The signal receiving unit is installed on the trainee and is used to receive radio electromagnetic wave signals and determine the received power of the radio electromagnetic wave signals.

[0010] The data processing unit determines the size of the obstacle between the firing unit and the trainee based on the transmission and reception power of the radio electromagnetic wave signal. If the size is lower than the set size threshold, an alarm message is issued and the trigger of the firing unit is locked.

[0011] On the other hand, embodiments of this application provide a danger warning method during shooting training, including:

[0012] Determine if there are any trainees directly in front of the firing unit;

[0013] Radio electromagnetic wave signals are emitted when there are trainees directly in front of the firing unit;

[0014] Receive radio electromagnetic wave signals and determine the received power of the radio electromagnetic wave signals;

[0015] The size of the obstacle between the firing unit and the trainee is determined based on the transmission and reception power of the radio electromagnetic wave signal. If the size is lower than the set size threshold, an alarm message is issued and the trigger of the firing unit is locked.

[0016] The danger warning device and method for shooting training disclosed in this application have the following advantages:

[0017] By utilizing the penetrating power of radio electromagnetic waves to penetrate obstacles, the power of the radio electromagnetic waves is weakened by the size of the obstacle. The size of the obstacle can be roughly determined based on the degree of weakening, providing the firing unit with a data basis for whether to lock on. Locking is only performed when the size of the obstacle is small, effectively ensuring the personal safety of the trainees. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] Figure 1-3 This is a schematic diagram of a danger warning device for shooting training provided in an embodiment of this application. This application provides a danger warning device for shooting training, including:

[0025] The data processing unit 200 is used to determine whether there are training personnel directly in front of the firing unit 500;

[0026] A signal transmitting unit 300 is disposed on the firing unit 500. The signal transmitting unit 300 is used to transmit a radio electromagnetic wave signal in front of the firing unit 500 when the data processing unit 200 determines that there is a training personnel directly in front of the firing unit 500.

[0027] The signal receiving unit 400 is installed on the trainee and is used to receive radio electromagnetic wave signals and determine the received power of the radio electromagnetic wave signals.

[0028] The data processing unit 200 determines the size of the obstacle 600 between the shooting unit 500 and the trainee based on the transmission and reception power of the radio electromagnetic wave signal. If the size is lower than the set size threshold, an alarm message is issued and the trigger of the shooting unit 500 is locked.

[0029] For example, the data processing unit 200 can be located locally, i.e., near the training ground, or in a remote data center, and communicate with equipment in the training ground via cloud technology. The radio electromagnetic wave signal emitted by the signal transmitting unit 300 is preferably an electromagnetic wave signal with a certain penetrating ability to ensure that the radio electromagnetic wave signal will not suffer significant loss due to air propagation over a distance of tens or even hundreds of meters, nor will it suffer excessive power loss due to penetrating the obstacle 600.

[0030] In the embodiments of this application, the signal transmitting unit 300 continuously or intermittently transmits radio electromagnetic wave signals at a fixed power, while the receiving power of the signal receiving unit 400 varies depending on the propagation medium, propagation distance, and the presence of obstacles 600. Therefore, the received power will change. When the signal receiving unit 400 receives the radio electromagnetic wave signal, it first measures its power and then sends the measured power, i.e., the received power data, to the data processing unit 200, where it is stored and processed.

[0031] Since this application uses radio electromagnetic wave signals with a certain penetrating ability, after the signal transmitting unit 300 transmits the radio electromagnetic wave signal, the radio electromagnetic wave signal will penetrate the obstacle and be received by the signal receiving unit 400. During the propagation process, the intensity of the radio electromagnetic wave signal will gradually decrease, especially when penetrating the obstacle, the change in intensity is relatively large. This is reflected in the data as a significant reduction in the received power of the radio electromagnetic wave signal compared to the transmitted power. The magnitude of this reduction is related to the distance between the shooting unit 500 and the trainee, as well as the size of the obstacle 600. Among these two influencing factors, the size of the obstacle 600 has the greatest impact. Moreover, the size of the obstacle 600 and the power difference can be uniquely determined through mathematical relationships. Therefore, the size of the obstacle 600 can be accurately simulated and determined through the power difference.

[0032] Furthermore, the size threshold needs to be determined based on the bullet penetration capability of the firing unit 500. Different size thresholds need to be set for different types of firing units 500. For example, pistol bullets have lower penetration capability, so the size threshold corresponding to pistols is smaller, while rifle bullets have higher penetration capability, so the size threshold corresponding to rifles is higher. The specific value of the size threshold needs to be determined experimentally. Bullet blocking experiments can be conducted using obstacles of various materials, and the maximum size that a common obstacle in field training can withstand bullet penetration should be used as the size threshold.

[0033] In one possible embodiment, the apparatus of this application further includes: a soldier positioning unit 100, disposed on the trainee, the soldier positioning unit 100 being used to collect the real-time position of the trainee; a weapon positioning unit, disposed on the firing unit 500, with at least one weapon positioning unit disposed at each end of the firing unit 500, the weapon positioning unit being used to collect the real-time position of the firing unit 500; and a data processing unit 200 including a direction calculation module 210 and a signal activation module 220, the direction calculation module 210 being used to determine the position and orientation of the firing unit 500 based on the real-time positions collected by the multiple weapon positioning units, and to determine whether there is a trainee directly in front of the firing unit 500 in conjunction with the real-time position of the trainee, and if there is, the signal activation unit 220 sending a activation command to the signal transmission unit 300, the signal transmission unit 300 responding to the activation command by transmitting a radio electromagnetic wave signal.

[0034] For example, after obtaining the positions of the trainee and the firing unit 500, the direction calculation module 210 can establish a coordinate system, convert the latitude and longitude positions of the trainee and the firing unit 500 into corresponding coordinates and fill them into the coordinate system, thereby determining the orientation of the firing unit 500. If the coordinates of the trainee are on the straight line of the orientation of the firing unit 500, the direction calculation module 210 can determine that the trainee is directly in front of the firing unit 500.

[0035] In one possible embodiment, the data processing unit 200 further includes a distance calculation module 240 and an obstacle simulation module 230. The distance calculation module 240 is used to determine the distance between the shooting unit 500 and the trainee. The obstacle simulation module 230 obtains the power difference value corresponding to the distance and uses the power difference value and the difference between the transmission power and the reception power of the radio electromagnetic wave signal to determine the size of the obstacle 600.

[0036] For example, since radio electromagnetic wave signals also experience a certain degree of attenuation when propagating in the air, and the degree of attenuation is proportional to the distance, considering propagation loss can make the size calculation of obstacle 600 more accurate. This application uses the power difference in air propagation as a theoretical value, and the difference between the transmitted power and the received power as the actual value. The theoretical value is the power difference at the current distance when there is no obstacle, while the actual value may include the influence of the obstacle. Therefore, the theoretical value will be less than or equal to the actual value. By subtracting the actual value from the theoretical value, the power difference caused by the obstacle 600 can be obtained. Based on this power difference, the size of obstacle 600 can be determined.

[0037] In one possible embodiment, the data processing unit further includes a power measurement module 250 and a data storage module 260. The signal transmitting unit 300 transmits radio electromagnetic wave signals to the signal receiving unit 400 at multiple distances at the start of training, and there are no obstacles 600 between the signal transmitting unit 300 and the signal receiving unit 400. The power measurement module 250 records the distance between the signal transmitting unit 300 and the signal receiving unit 400 and the corresponding power difference, and stores it in the data storage module 260.

[0038] For example, the attenuation of radio electromagnetic wave signals by air propagation is affected by the actual air quality, so it is necessary to measure the air propagation attenuation in the actual training venue before training.

[0039] During actual measurement, no obstacles are allowed between the trainee and the firing unit 500. The firing unit 500 is then positioned directly facing the trainee, ensuring that the radio electromagnetic wave signal emitted by the signal transmitting unit 300 can be successfully received by the signal receiving unit 400. Finally, the power measurement module 250 records the current distance and received power, calculates the difference between them and the transmitted power, and establishes a correspondence between the distance and power differences. Subsequently, the distance between the trainee and the firing unit 500 is adjusted, and the above operation is repeated to obtain multiple sets of corresponding distance and power difference values.

[0040] In one possible embodiment, the power measurement module 250 fits multiple sets of recorded distance and power difference data to form a distance-power difference curve and stores it in the data storage module 260. The obstacle simulation module 230 queries the corresponding power difference on the distance-power difference curve based on the distance between the shooting unit 500 and the trainee.

[0041] For example, since the distance and the corresponding power difference recorded by the power measurement module 250 are discrete data points, the distance between the trainee and the shooting unit 500 in actual training may be any value. Therefore, the power measurement module 250 needs to use an algorithm such as the least squares method to fit the discrete data points into a continuous curve. Based on this continuous curve, the obstacle simulation module 230 can obtain the power difference at any distance.

[0042] In one possible embodiment, the shooting unit 500 is also equipped with a light receiving unit, and the trainee is also equipped with a light emitting unit. When the light receiving unit receives the light signal emitted by the light emitting unit, the signal emitting unit 300 will emit a radio electromagnetic wave signal so that the power measurement module 250 can record the power difference at different distances.

[0043] For example, since the power measurement module 250 requires the signal transmitting unit 300 to be directly aligned with the signal receiving unit 400 during the measurement process, this application uses an optical signal to achieve alignment between the two. Based on the principle of rectilinear propagation of light, when the optical receiving unit can normally receive the optical signal from the optical transmitting unit, it indicates that the signal transmitting unit 300 and the signal receiving unit 400 are also aligned. At this time, the radio electromagnetic wave signal emitted by the signal transmitting unit 300 can be received by the signal receiving unit 400 through the shortest path.

[0044] In one possible embodiment, the shooting unit 500 is also provided with an alarm unit, and the data processing unit 200 further includes an alarm module 270. When the data processing unit 200 determines that the size is lower than the size threshold, the alarm module 270 sends an alarm message to the alarm unit, and the alarm unit generates a corresponding alarm prompt.

[0045] For example, the alarm unit can display alarm prompts in various ways such as beeping, voice, flashing lights or vibration, so that the shooting personnel are aware that there are other training personnel in front of them and stop shooting in time.

[0046] Embodiments of this application also provide a danger warning method during shooting training, including:

[0048] Radio electromagnetic wave signals are emitted when there are trainees directly in front of the firing unit 500;

[0050] The size of the obstacle 600 between the firing unit 500 and the trainee is determined based on the transmission and reception power of the radio electromagnetic wave signal. If the size is lower than the set size threshold, an alarm message is issued and the trigger of the firing unit 500 is locked.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of this application.
