Description

Technical Field

[0001] The present invention relates to the technical field of shooting training applications, and further relates to a multi-link dangerous event target-changing target machine and its training method. It is mainly used for shooting training and can also be used for switching different promotional contents or indicating directions in fields such as advertising and guiding signs. Background Art

[0002] In fields such as military and police close-quarter tactical training and entertainment simulation shooting, shooting techniques of various target machines that can rotate, rise and fall, or tilt are widely used. The basic principle of these techniques is to control the target machine to produce an action of presenting the target, but the form and content of the target itself do not change, or it is just a change between the front and back sides of a target. In the process of special security guards or handling street tactics, house searches, and mass incidents, since the distance between the duty officers and the crowd is very close, when there are dangerous attackers or actions in the crowd, training on how to quickly respond and handle dangerous event scenarios is particularly important. For example, the distance and position between the training personnel and the important person protected by the guards at this time, as well as the reaction speed and action accuracy of the training personnel individually and as a team, will have a fatal impact on the result of the guard mission. Therefore, various target machines of the prior art are not suitable for the training requirements of force application subjects such as special security guards, house searches, and mass incident handling because they cannot present target forms of different dangerous event forms in a single target presentation. Summary of the Invention

[0003] Aiming at the above technical problems, the purpose of the present invention is to provide a multi-link dangerous event target-changing target machine, which can store multiple hidden targets corresponding to different dangerous events and can quickly change the target surface form of a non-dangerous target originally presented in front of the training personnel into the target surface form of different dangerous situations during training, so as to improve the reaction of the training personnel to sudden situations.

When the target is in a hidden position, the end of the power slide rail connected to the target lifting slide rail is in the lowest position, and the spring is in a stretched state, which can provide starting power for the target to switch from the hidden position to the exposed position, thereby accelerating the target's target-exiting action.

[0012] The multi-link dangerous event target changing target machine described above also includes a target detection component, which includes a live ammunition detection component for detecting live ammunition impact and a light spot detection component for detecting laser shooting.

[0038] Reference Manual Attached Figure 1 The present invention provides a multi-link dangerous event target changing machine. During training, the target corresponding to the non-dangerous event form originally displayed in front of the trainee can be quickly replaced with a target corresponding to a different dangerous event form, so as to improve the suddenness and confrontation of the trainee during training.

[0039] In one embodiment, the multi-danger event target changing drone provided by the present invention includes: a target stand and a plurality of target assemblies mounted on the target stand.

[0040] The target frame has a front baffle 15, and a plurality of target components are located on the back of the front baffle 15, and are spaced apart along the front-back direction of the target frame. The target component includes a target seat 13 and a target 14. The target seat 13 can move in the vertical direction. The target 14 is installed on the target seat 13 and has a hidden position and an exposed position. When the target 14 is in the hidden position, the target 14 is blocked by the front baffle 15. When the target 14 is in the exposed position, the target 14 is located above the front baffle 15. The front baffle 15 has a first pattern, and the target 14 has a second pattern. When the target 14 is in the exposed position, the first pattern and the second pattern are adapted to form a complete human figure.

[0041] Each target 14 corresponds to an event target surface form, and the event target surface form includes a form of no dangerous event and forms of a plurality of predetermined dangerous events. In the initial state, the target corresponding to the form of no dangerous event is in front of other targets and in the exposed position, and a plurality of targets corresponding to the forms of predetermined dangerous events are in the hidden position. Sequentially controlling the continuous lifting and lowering transformation of a plurality of targets 14 can enable a plurality of event target surface forms to be in the exposed position in sequence, forming a dangerous action process of a continuous picture. Exemplarily, different targets 14 have different event target surface forms. Sequentially controlling the lifting and lowering of the targets 14 can enable different event target surface forms to be exposed in sequence, presenting an effect similar to an animation, and can more realistically simulate the actual combat state.

[0042] In this embodiment, the front baffle 15 can be made of bulletproof material, which can prevent the bullet from being shot at the front baffle 15 due to the operator's mistake of the training personnel, and prevent the bullet from passing through the front baffle 15 and acting on the target 14 blocked by the front baffle 15, affecting the structural integrity of the target 14 and further affecting the accuracy of the subsequent training evaluation results of the training personnel.

[0043] The target seat 13 and the target 14 can be connected by bonding, integral molding and other methods. The integral molding method is preferably used, which helps to save production costs and improve the overall assembly efficiency of the target machine.

[0044] To better illustrate the present invention, in this embodiment, the side of the target surface facing the shooter is defined as the front, the other side is defined as the back, the direction facing the front is defined as the front, and the direction facing the back is defined as the back.

[0045] Refer to the attached Figure 1 to the specification. The target frame includes a target machine base plate 11 and a bracket. The bracket is installed on the target machine base plate 11 and includes two front baffle brackets 12 spaced apart. The front baffle 15 is installed between the two front baffle brackets 12. In this embodiment, the length direction of the target machine base plate 11 is defined as the transverse direction, and the width direction of the target machine base plate 11 is defined as the longitudinal direction. Then the two front baffle brackets 12 are spaced apart along the transverse direction, and a plurality of target components are spaced apart along the longitudinal direction.

[0046] The front baffle 15 is used to block the target 14. In the natural state, the target 14 is located at the exposed position, that is, the target 14 is located above the front baffle 15. By driving the target seat 13 to drive the target 14 downward until the target 14 is hidden behind the front baffle 15, the target 14 enters the hidden position. Therefore, the size of the front baffle 15 is not less than the size of the target 14. In this embodiment, the front baffle 15 has a square shielding surface, and a predetermined pattern is distributed on the shielding surface of the front baffle 15 and the target surface of the target 14. When the target 14 is in the exposed position, the images on the shielding surface and the target surface are combined to form an image in a specific dangerous situation. For example, the lower body image of the attacking person is distributed on the front baffle 15, and the upper body image of the attacking person in different attacking postures is distributed on the target 14. The lower body image and the upper body image are combined to form a human body posture image in a specific dangerous event.

[0047] Refer to the attached drawings of the specification again Figure 1 In addition, the target assembly of this embodiment further includes a target guiding groove 27. The target guiding groove 27 is installed on the base plate 11 of the target machine. One end of the target seat 13 in the transverse direction is connected to the lifting slide rail, and the other end is embedded in the target guiding groove 27. The target seat 13 is driven by the driving component to move in the vertical direction. Of course, the target also moves along the vertically extending target guiding groove 27, so as to improve the movement stability of the target seat 13.

[0048] Refer to the attached drawings of the specification Figure 4 In some embodiments, the target 14 and the target lifting slide rail 22 are detachably connected through a positioning and matching component, so as to replace the target 14 in time when it is damaged to ensure the replacement efficiency of the target 14. Specifically, the positioning and matching component includes a first magnetic attachment provided on the target 14 and a second magnetic attachment provided on the target lifting slide rail 22. There is a magnetic attraction force between the first magnetic attachment and the second magnetic attachment. In this way, under the drive of the positioning and matching component, the target lifting slide rail 22 is closely attached to the target seat 13, which provides convenience for the replacement of the target seat 13 and the target 14 thereon.

[0049] The first magnetic attachment is assembled on the outer wall of the target seat 13, and the second magnetic attachment is assembled on the end face of the target lifting slide rail 22 facing the first magnetic attachment. When assembling the target seat 13, the operator can align the target seat 13 with the predetermined position of the target lifting slide rail 22. Due to the attraction between the first magnetic attachment and the second magnetic attachment, they are attracted and joined together after contact.

[0050] In some embodiments, both the first magnetic attachment and the second magnetic attachment are magnets, specifically square strong magnets, and the polarities of the first magnetic attachment and the second magnetic attachment are opposite, so they can attract each other (for example, the polarity of the first magnetic attachment is the N pole and the polarity of the second magnetic attachment is the S pole; or the polarity of the first magnetic attachment is the S pole and the polarity of the second magnetic attachment is the N pole). Thus, using the principle of attraction between opposite poles of magnets, the target seat 13 and the target lifting slide rail 22 are tightly connected together.

[0051] It can be understood that in some other embodiments, only one of the first magnetic attachment and the second magnetic attachment is a magnet with magnetism, and the other can be formed of a material that can be attracted by a magnet, such as one or more of iron, cobalt, and nickel.

[0052] The number and installation positions of the first magnetic attachment and the second magnetic attachment are not limited. In some embodiments, the target seat 13 is only provided with one first magnetic attachment, and the target lifting slide rail 22 is only provided with one second magnetic attachment. In some other embodiments, the number of the first magnetic attachments is multiple, and there is only one second magnetic attachment. The multiple first magnetic attachments are attracted to the second magnetic attachment, increasing the attraction between the target lifting slide rail 22 and the target seat 13, and can further improve the convenience and reliability of installation.

[0053] As a preference, there are 2 first magnetic attachments provided on the target lifting slide rail 22. The first magnetic attachments are selected as strong magnets 33. The strong magnets 33 can be fixed in the target lifting slide rail 22 by bonding. The two strong magnets 33 are distributed at intervals in the vertical direction. The second magnetic attachment is selected as the target adsorption and fixing iron block 31. The target adsorption and fixing iron block 31 is fixed on the target seat 13 by a target positioning screw 32. The target positioning screw 32 is partially located outside the target adsorption and fixing iron block 31. Further, a target positioning hole 221 matching the target positioning screw 32 is also opened on the target lifting slide rail 22. The target positioning screw 32 can be received through the target positioning hole 221 to achieve effective positioning of the target seat 13, which helps to improve the convenience of installation.

[0054] The driving assembly also includes a transmission assembly, which includes a power slide rail bracket 24 and a power slide rail 25. The power slide rail bracket 24 is installed on the target machine base plate 11 and extends in the vertical direction. The power slide rail 25 includes a fixed rail and a folding rail. One end of the fixed rail is hinged to the upper part of the power slide rail bracket 24. The folding rail is slidably connected in the fixed rail. The folding rail includes multiple sections of guide rails that can relatively change the working length of the entire track. One end of the fixed rail between the rotation point and the output point is connected to the drive motor 26, and is driven by the drive motor 26 to move up and down along the drive motor 26. The folding rail is slidably connected in the fixed rail, and the other end is hinged to the target lifting slide rail 22, which can drive the target lifting slide rail 22 to move up and down.

[0055] When the target 14 is transferred from the exposed position to the hidden position, the folding rail is driven to move by the driving motor 26. Since one end of the fixed rail is hinged on the power slide rail bracket 24, the fixed rail will flip during the movement of the folding rail, and drive the folding rail to flip synchronously, thereby pressing down the target lifting slide rail 22, so that the target lifting slide rail 22 drives the target seat 13 and the target 14 to move downward.

[0056] In some embodiments, one end of the power rail 25 is hinged at the bottom of the target lifting rail 22, and the end of the power rail 25 facing away from the target lifting rail 22 is connected to a spring 23, and the two ends of the spring 23 are respectively connected to the fixed rail and the target base plate 11. When the target 14 is in the hidden position, the end of the power rail 25 connected to the target lifting rail 22 is in the lowest position, and the spring 23 is in a stretched state, which can provide starting power for the target 14 to switch from the hidden position to the exposed position, and accelerate the target 14 to come out of the target. After the drive motor 26 stops applying force to the folding rail, the spring 23 drives the fixed rail to reversely flip through its own elastic deformation, and drives the folding rail to flip synchronously, thereby lifting the target lifting rail 22, so that the target lifting rail 22 drives the target seat and the target 14 to move upward to the exposed position.

[0057] Because the spring 23 is in a stretched state when the target 14 is in the hidden position, when the initial target-output force of the driving motor 26 is small, the spring 23 can provide a starting power to enable the target 14 to quickly enter the exposed position, and can quickly replace the target corresponding to the non-dangerous event form in front of the trainee with a target of a predetermined dangerous event form, which can improve the suddenness and confrontation of the trainee during training.

[0058] In one embodiment, the multi-link dangerous event target changing machine provided by the present invention also includes a target detection component, which includes a live ammunition detection component for detecting live ammunition impact and a light spot detection component for detecting laser shooting. The target detection component is used to detect the live ammunition hitting position and / or the laser shooting position of the target to obtain the shooting hitting result information.

[0059] Preferably, the live ammunition detection component is a live ammunition impact sensor 28 installed on the target stand 14. A control electrical box 29 is installed on the base plate 11 of the target drone. The live ammunition impact sensor 28 is electrically connected to the control electrical box 29 and is used to detect whether the training personnel miss the target during shooting. Only when the target is not missed, the control electrical box 29 controls the operation of the target inspection component electrically connected thereto to obtain the specific position information of the bullet shooting. The control electrical box 29 is also electrically connected to the drive motor 26 and is used to control the lifting of each target 14. The light point detection component is a laser sensor 34 installed on the target stand 14.

[0060] In some embodiments, the multi-link dangerous event target-changing target drone provided by the present invention further includes a camera unit and client software. The camera unit includes a viewpoint direction camera 30. The viewpoint direction camera 30 is installed on the target rack and is used to collect dynamic picture information of the emergency response actions of the training personnel observed from one side of the target. Through the client software, when the target 14 with a dangerous event appears, the action reaction situation of the training personnel seen from the attacker's direction can be displayed.

[0061] The present invention also provides a multi-link dangerous event training method, which utilizes the above-mentioned multi-link dangerous event target-changing target drone. The method includes the following steps:

[0062] S1: Collect images of standard evasion and shooting actions, and use deep learning-based human pose recognition technology, such as using convolutional neural network technology, to accurately locate the skeletal key node map of the standard action images and establish a limb action library.

[0063] The human pose recognition technology is an existing technology and not the innovation point of this application. The principle can refer to the relevant content disclosed in the invention patent with the application number 2022103771299. For the sake of saving space, this application will not introduce it in detail.

[0064] S2: Configure multiple targets, install the targets on the target stands, and each target corresponds to an event target surface form. The event target surface form includes a non-dangerous event form and multiple predetermined dangerous event forms. In the initial state, the target corresponding to the non-dangerous event form is in front of other targets and in an exposed position, and other targets are in a hidden position.

[0065] S3: Control the target corresponding to the non-dangerous event form to be converted from the exposed position to the hidden position, and control the target corresponding to the predetermined dangerous event form to be converted from the hidden position to the exposed position.

[0066] S4: The training personnel perform target shooting training actions based on the exposed dangerous event form target. The training actions include evasion actions and shooting actions. The emergency action picture information of the training personnel is collected in real time through the camera component.

[0067] S5: Use gesture recognition technology to recognize the information of the key points of the trainer's bones in real time, and compare the recognition results with the information in the limb movement library. When the comparison conclusion is that the trainer's limb movement is a shooting action, go to S6; when the comparison conclusion is that the trainer's limb movement is an evasion action, go to S7;

[0068] S6: Locate the shooting position of the target to obtain target shooting information;

[0069] S7: Extract the video of the trainer's limb movement and display it through the client software to provide a basis for evaluating the trainer's action reaction speed, occlusion efficiency or self-evasion situation.

[0070] In some embodiments, the multi-linked dangerous event target-changing target machine provided by the present invention can also be applied to the traffic field. The target surface of the target is distributed with predetermined traffic indication patterns. By controlling the target to rise or fall, the target can be in an exposed or hidden state, enabling traffic participants to accurately understand the current traffic conditions and having a certain promoting effect on traffic guidance.

[0071] It should be noted that the above embodiments can be freely combined according to needs. The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.

8. The training method of the multi-link dangerous event target-changing target machine, characterized in that: The multi-link dangerous event target-changing target machine as described in any one of claims 1-7 is adopted. This training method includes the following steps: S1: Collect images of standard evasion and shooting actions, use deep learning-based human pose recognition technology to accurately locate the skeletal key node map of the standard action images, and establish a limb action library; S2: Configure multiple targets, install the targets on the target seats, and each target corresponds to an event target surface form. The event target surface form includes a form without dangerous events and forms of multiple predetermined dangerous events. In the initial state, the target corresponding to the form without dangerous events is in front of other targets and is in an exposed position, and other targets are in a hidden position; S3: Control the target corresponding to the form without dangerous events to switch from the exposed position to the hidden position, and control the targets corresponding to the forms of predetermined dangerous events to switch from the hidden position to the exposed position; S4: The training personnel perform target shooting training actions based on the exposed dangerous event form targets. The training actions include evasion actions and shooting actions. The emergency action picture information of the training personnel is collected in real time through the camera component; S5: Real-time identify the skeletal key point information of the training personnel through the pose recognition technology, and compare the recognition result with the information in the limb action library. When the comparison conclusion is that the limb action of the training personnel is a shooting action, go to S6. When the comparison conclusion is that the limb action of the training personnel is an evasion action, go to S7; S6: Locate the shooting position of the target to obtain shooting information; S7: Extract the limb action video of the training personnel and display it through the client software.
