Description

Technical Field

[0001] This invention belongs to the field of optoelectronic shooting equipment technology, specifically relating to a laser shooting training system using optical fiber, fluorescence, and linear array optoelectronic sensors. Background Technology

[0002] Laser shooting training systems are mainly used for shooting training, assessment, and competition under non-live-fire conditions, and can also be used to test shooters' shooting skills.

[0003] Existing laser shooting training systems consist of a laser shooting gun, a target box, and a scoring display. Traditional target drones use a rear-mounted camera to capture the laser spot (simulating the impact point of a live bullet), and then a microprocessor calculates the spot's position. The target drone communicates with the laser shooting gun via radio (such as Bluetooth) to receive the gun's status (such as preload and firing). The shooting result is detected by the target drone's internal rear-mounted camera, and the data is collected and transmitted by a computer. Finally, the shooting score is displayed on a computer screen or a scoring display. Existing laser shooting training reporting systems have the following main problems and disadvantages:

[0004] First, the shooting process and results are not intuitive and cannot be perceived. Due to factors such as ambient light interference, laser shooting guns mostly use invisible lasers as the light source, making the light spot invisible during shooting. Furthermore, the process of traditional target drones detecting the laser signal emitted by the laser gun through an internal rear camera and then relying on a computer for data collection and transmission is also invisible and imperceptible to humans. Therefore, when shooters question their results, they cannot receive a fair explanation. During training or competitions, shooting results cannot be visually verified through target paper like in live-fire shooting.

[0005] Secondly, the accuracy of shooting score recognition is low, with significant errors. Factors such as camera frame rate, field of view, resolution, and ambient light can affect recognition accuracy, resulting in large errors. Furthermore, the camera itself has optical distortion, and since the camera and target are not on the same mounting plane, the camera needs to be recalibrated before each use.

[0006] Third, its expandability is limited by the working principle of the camera. If a larger target surface is required, while increasing the size of the target surface, the distance between the camera and the target surface needs to be increased due to the influence of the rear camera's field of view, which in turn increases the depth of the target box and thus increases the volume of the target box.

[0007] Fourth, the system has poor anti-interference performance. Since the target drone needs to communicate with the laser shooting gun and receive the status of the laser shooting gun (such as preload, firing, etc.), the current solution uses wireless communication methods such as Bluetooth. However, in actual situations, because wireless communication is in an open environment, the electronic system has poor anti-interference performance. In particular, there is a possibility of man-made radio interference sources, or even hidden interference activities outside the range wall, deliberately affecting the shooting results. Summary of the Invention

[0014] Furthermore, the first power module includes a power controller and a power supply component, which are electrically connected; the power supply component is a built-in rechargeable battery, a removable rechargeable battery, or a disposable battery.

[0015] Furthermore, the first optical communication device includes an optical signal processing circuit and a laser, the optical signal processing circuit being electrically connected to the laser, and the first controller being electrically connected to the optical signal processing circuit.

[0016] Furthermore, the laser shooting training system also includes a front-facing camera for capturing images of the fluorescent spot formed on the display device from the shooter's side at the point of impact; the second controller is connected to the front-facing camera.

[0017] Furthermore, the laser shooting training system also includes a digital display screen for displaying the bullet impact point, shooting score, and shooting parameters; the second controller is connected to the digital display screen.

[0018] Furthermore, the laser shooting training system also includes a sight for the shooter to aim at the target machine; the sight can be a mechanical sight, an optical sight, or an electronic sight.

[0020] Furthermore, both the first and second controllers are integrated with wireless communication modules for receiving external remote control commands.

[0021] The above technical solution adopted in this application has at least the following beneficial effects: The laser shooting training system provided by this application includes a shooting gun and a target machine; the shooting gun includes a gun body, with a light emitting module and a first optical communication device disposed at the front end of the gun body; a first controller, a first power module, and a posture sensor are disposed inside the gun body; a firing device is disposed at the trigger position of the gun body; the firing device is electrically connected to the light emitting module, the first power module, and the first controller respectively; the first controller is electrically connected to the first optical communication device, the posture sensor, and the firing device respectively; the target machine includes a housing, with a display device disposed on the surface of the housing, and the surface of the display device is coated with a fluorescent agent coating sensitive to invisible light; an optical fiber assembly is fixedly disposed inside the fluorescent agent coating; a second controller, a second optical communication device, and a second power module are disposed inside the housing; the second controller is electrically connected to the display device, the optical fiber assembly, the second optical communication device, and the second power module respectively.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Please see Figure 1 , Figure 1 This is a schematic diagram illustrating the structure of a laser shooting training system using fiber optic, fluorescent, and linear array photoelectric sensors according to an exemplary embodiment. Figure 1 As shown, this laser shooting training system using fiber optic, fluorescent, and linear array photoelectric sensors includes a shooting gun and a target. The shooting gun emits light signals that illuminate the target to simulate bullet firing. The shooting gun includes a gun body, with a light emitting module 3 and a first optical communication device 10 located at the front end. Inside the gun body are a first controller 4, a first power module 7, and a posture sensor 9. A firing device 8 is located at the trigger position of the gun body. The firing device 8 is electrically connected to the light emitting module 3, the first power module 7, and the first controller 4. The first controller 4 is electrically connected to the first optical communication device 10, the posture sensor 9, and the firing device 8.

[0031] The target machine includes a housing 1, on the surface of which a display device 2 is disposed, and the surface of the display device 2 is coated with a fluorescent agent coating that is sensitive to invisible light; an optical fiber assembly 15 is fixedly disposed inside the fluorescent agent coating; a second controller 14, a second optical communication device 12, and a second power module 13 are disposed inside the housing 1; the second controller 14 is electrically connected to the display device 2, the optical fiber assembly 15, the second optical communication device 12, and the second power module 13 respectively.

[0032] Specifically, in this application, the light emitting module 3 is used to emit light signals to the display device 2 of the target machine. The emitted light is a visible wavelength laser, but it can also emit invisible wavelength lasers, such as ultraviolet and infrared lasers. To eliminate the influence of ambient light, invisible wavelength lasers are preferred. When the invisible wavelength laser emitted by the light emitting module 3 irradiates the phosphor coated on the surface of the display device 2, the phosphor is excited and produces a visible fluorescent spot. At this time, the impact point can be directly recorded by a recorder, or the impact point can be photographed using the front-facing camera 11 (described later). After shooting, the system-generated photos can be retrieved as needed to eliminate any doubts about the shooting results.

[0033] Furthermore, the gun body of this application is also equipped with a first optical communication device 10, which is used to transmit the pulse train signal modulated by the first controller 4 as an optical signal to the target machine. The first optical communication device 10 can be set separately from the optical transmitting module 3, or it can be set integrally with the optical transmitting module 3, with the optical transmitting module 3 directly transmitting the modulated pulse train signal. The first optical communication device 10 designed in this application uses an invisible wavelength laser light source as a carrier. The shooting gun uses the first optical communication device 10 to transmit invisible light signals to the target machine for communication, which has good directionality, strong pointing, concentrated energy, strong anti-interference ability, and good safety.

[0034] In this application, the optical emitting module 3 and the first optical communication device 10 can emit lasers in the visible wavelength range, or lasers in the invisible wavelength range, such as ultraviolet and infrared. To eliminate the influence of ambient light, lasers in the invisible wavelength range are preferred, such as ultraviolet light with a wavelength of less than or equal to 360 nm, or infrared light with a wavelength of greater than or equal to 800 nm. The optical emitting module 3 and the first optical communication device 10 can use lasers such as LED lasers and gas lasers, and are connected to an optical signal processing circuit. In another embodiment, the first controller 4 itself acts as an optical signal processing circuit, directly controlling the optical emitting module 3 and / or the first optical communication device 10 to emit optical pulse signals.

[0035] Furthermore, the firing device 8 described in this application includes a trigger, a force feedback device, and a firing sensor 6. The force feedback device is located at the rear of the gun body and is used to simulate the recoil of the firearm, allowing the shooting gun to more closely simulate a real firearm. The firing sensor 6 is used to detect firing parameters when the trigger is pulled, and the first controller 4 is electrically connected to the firing sensor 6. When the trigger of the firing device 8 is pulled, the aforementioned light emitting module 3 is connected to the first power supply module 7 contained within the gun body, or a command is sent to the controller of the light emitting module 3, causing the light emitting module 3 to emit a laser and illuminate the display device 2 on the target. In another embodiment, the firing device 8 can send a command to the first controller 4 (described later), and the first controller 4 controls the light emitting module 3 to emit a laser. The force feedback device can include components such as a counterweighted pull spring, a vibration motor, and an eccentric wheel.

[0036] Furthermore, the firing sensor 6 installed in the firing device 8 is mainly used to detect various firing parameters when the shooter pulls the trigger, such as the pulling time, pulling force, and average firing time. It can be used to assist in training rapid-fire exercises. The firing sensor 6 can be a sensor such as a Hall displacement sensor, and the parameters acquired by the firing sensor 6 are transmitted to the aforementioned first controller 4. In another embodiment, the first controller 4 can also directly acquire the firing parameters from the firing device 8.

[0037] Furthermore, in this application, the shooting rifle is also equipped with a posture sensor 9, which is used to sense and acquire the shooter's posture parameters when holding the rifle, such as the tilt angle of the rifle and the shaking when holding the rifle. For example, it can be used to assist in training the stability of the sniper's rifle holding. The posture sensor 9 can be a three-axis gyroscope, a three-axis accelerometer, a three-axis electronic compass, etc. The posture sensor 9 transmits the acquired posture parameters to the first controller 4. In another embodiment, the posture sensor 9 can be integrated into the first controller 4.

[0038] Specifically, in this application, firing parameters and posture parameters can be collectively referred to as shooting parameters, which can be used as a reference in the shooter training process. These parameters are transmitted to the first controller 4 and recorded. The first controller 4 can modulate the collected shooting parameters into a series of pulse train signals.

[0039] Furthermore, the first power module 7 in this application includes a power controller and a power supply component, which are electrically connected; the power supply component is a built-in rechargeable battery, a removable rechargeable battery, or a disposable battery.

[0040] Furthermore, in this application, the shooting rifle also has a sight 5 on its body, which is used by the shooter to aim at the target. Depending on training or competition requirements, it can use mechanical sights, optical sights, photoelectric sights, or other devices. In another embodiment, the light emitting module 3 can emit visible laser light, serving as a laser sight.

[0041] Specifically, in this application, the target machine has a housing 1 for supporting and accommodating all the equipment inside. A display device 2 for displaying targets is suspended or embedded in the surface of the housing 1. The display device 2 can be an optoelectronic display panel such as an LCD (liquid crystal display) panel or an EPD (electronic ink, e-paper display) panel, or it can use a projector for imaging. The display device 2 can display targets such as chest targets, human figures, 10-meter air pistol targets, 10-meter air rifle targets, police pistol targets, and military pistol targets on the optoelectronic display panel according to the actual needs of training or competition, by changing the printed targets or using the second controller 14. In this application, the surface of the display device 2 is coated with a fluorescent agent, which can be excited by the laser emitted by the light-emitting module 3 to display a visible fluorescent spot, allowing shooters, observers, and referees to directly observe it.

[0042] The aforementioned fluorescent agent is preferably transparent to reduce its impact on the clarity of the target displayed on the display device 2. The fluorescent agent can be an organic fluorescent agent, an inorganic fluorescent agent, or other fluorescent agent that can be excited by a laser emitted by the light-emitting module 3. Preferably, a long-afterglow fluorescent agent that is not excited by visible light is used to avoid interference from ambient light and to increase the observation time. In another embodiment, the display device 2 may also use only target paper, metal, or patterned glass or transparent plastic targets, the surface of which is also coated with a fluorescent coating.

[0043] Therefore, the proposed solution involves coating the surface of the target machine with a fluorescent agent that is sensitive to invisible light. When the laser emitted by the shooting gun illuminates the surface of the target machine, the fluorescent agent coating is excited, forming a visible light spot that can be recognized by the human eye, thus achieving intuitive visibility of the shooting effect.

[0044] Please refer to Figure 2 In this application, the inner side of the fluorescent coating is an optical fiber assembly 15, which includes an optical fiber layer and a linear array photodetector. The linear array photodetector is located at the output end of the optical fiber 18, and the second controller 14 is electrically connected to the linear array photodetector. The optical fiber layer is composed of longitudinally and transversely arranged optical fibers 18, which form the XY axis, i.e., the X-axis 16 and the Y-axis 17 of the optical fiber layer. (Refer to...) Figure 3When the laser gun fires, the optical fiber 18 transmits the received light to a linear array photoelectric sensor assembly at one end of the optical fiber 18, such as a photodiode 19 or a charge-coupled device (CCD) image sensor. After the microprocessor reads the signal from the linear array photoelectric sensor, it calculates the coordinates of the light spot position using a corresponding algorithm, thereby determining the shooting score and improving the accuracy of the shooting score recognition. This application has an optical fiber layer fixedly installed inside the target surface of the target machine. The optical fiber layer is composed of longitudinally and transversely arranged optical fibers, which form the XY axis. This ensures that the target box thickness does not increase with the target surface area during use, improving the system's applicability and reducing equipment costs. Furthermore, since the optical fibers are physically fixed to the target surface, the XY axis coordinate data does not need to be transformed or calibrated before each use, making it convenient and quick to use. The target machine does not need to be recalibrated each time it is used.

[0045] The calculation of the spot position coordinates is implemented using the existing gray-scale centroid algorithm. According to the gray-scale distribution characteristics in the cross section of each row of light stripes, the gray-scale centroid points of the light stripe region are calculated and extracted row by row in the direction of the row coordinates. These points are used to represent the center point of the light stripe in the cross section. Finally, all the center points are fitted to form the center line of the light stripe. Alternatively, an improved gray-scale centroid algorithm can be used to calculate the spot position coordinates, such as [1] Tao Jun, Zhang Xia. Sub-pixel positioning algorithm for the center of the light spot in fiber optic sensing system [J]. Computer Engineering, 2010, 36(19):31-33.

[0046] Furthermore, the second power module 13 disposed within the target drone's housing 1 can be a cable connecting to an external power source, a built-in rechargeable battery, a removable rechargeable battery, or a disposable battery, used to power all equipment on the target drone. In another embodiment, the second power module 13 is also equipped with a power controller, which can remotely control the power switch.

[0047] Furthermore, in another embodiment, the laser shooting training system includes a front-facing camera 11, with the second controller 14 connected to the front-facing camera 11. The front-facing camera 11 can be optionally mounted in front of the target machine to capture images of the fluorescent spot formed by the bullet impact point on the display device 2 from the shooter's side, thereby obtaining accurate and undisputed shooting results. This application uses a front-facing camera 11 mounted on the target machine to capture images of the fluorescent spot. After shooting, the system-generated images can be retrieved as needed to eliminate any doubts about the shooting results.

[0048] Furthermore, in another embodiment, the laser shooting training system also includes a digital display screen, with the second controller 14 connected to the digital display screen to display the bullet impact point, shooting score, and shooting parameters. This digital display screen can establish a connection with the target machine using wired or wireless methods such as Ethernet cable, WiFi, or Bluetooth. In another embodiment, the digital display screen can be a terminal device with software installed, such as a computer, mobile phone, or tablet computer, and can also remotely control the target machine by setting various parameters.

[0049] Furthermore, in another embodiment, the second power module 13 is provided with a control circuit that can receive instructions from the second optical communication device 12. The shooting gun can activate the photocell or photodiode 19 inside the second optical communication device 12 of the target machine through the light signal emitted by the first optical communication device 10, thereby controlling the second power module 13 to realize remote power-on and power-off operations.

[0050] Furthermore, in another embodiment, the first controller 4 of the shooting gun and the second controller 14 of the target machine are also integrated with wireless communication modules, which can receive external remote control commands and remotely control them to set various parameters.

[0051] Furthermore, in another embodiment, the present application also provides a simulation feedback module for the shooting gun, which includes a speaker for simulating the sound during shooting; the speaker is connected to the firing device 8 and / or the first controller 4.

[0052] Reference Figure 4 , Figure 4 A block diagram of a laser shooting training system is shown. The laser shooting training system designed in this application mainly includes a laser emitting module 3, a light source acquisition module, an image processing module, and a target reporting terminal. The laser emitting module 3 emits a laser beam to the light source acquisition module. The target surface printing layer and optical fiber layer in the light source acquisition module display the laser spot position. The image sensor in the image processing module then acquires the light signal of the spot position, converts the light signal into an electrical signal, and sends it to the microprocessor to calculate the spot position coordinates, thereby obtaining the shooting score, which is displayed on the corresponding target reporting terminal. The laser emitting module 3 can be implemented using a light emitting module 3, the image sensor can be implemented using a linear array photoelectric sensor, and the target reporting terminal can be implemented using a digital display screen.
