Description

Technical Field

[0001] This invention relates to the field of target range testing technology, and in particular to a remote zeroing system and method for photoelectric targets based on laser characteristics. Background Technology

[0002] Long-range precision shooting is an effective combat tactic. When conducting long-range precision shooting, ballistic compensation is usually completed quickly using a gun-mounted ballistic computer or laser rangefinder.

[0003] In existing technology, zeroing a firearm can only be done by finding the red visible laser spot emitted by the target within 50-100 meters. However, this close-range zeroing method has significant drawbacks when applied to long-range shooting. When the target is far away, the laser spot often deviates significantly, making it impossible to find the target and thus preventing normal rangefinding. This completely eliminates the ballistic compensation function, greatly reducing shooting efficiency and accuracy. Summary of the Invention

[0017] Both the first integrated circuit board and the first battery compartment are mounted on the second base plate. The first battery compartment is connected to the first integrated circuit board and is used to supply power to the first integrated circuit board.

[0018] The transmitting antenna extends from the second base plate after being connected to the wireless communication module on the first integrated circuit board. The wireless communication module is wirelessly connected to the wireless receiving device through the transmitting antenna.

[0019] Optionally, the photoelectric target further includes a fixed side frame and a three-layer partition plate;

[0020] The three layers of partition plates are welded in parallel within the fixed side frame, which is a rectangular side frame.

[0021] The protective layer, the sensing layer, and the acquisition layer are each threadedly connected to one of the partition plates.

[0022] Optionally, the wireless receiving device includes a display screen and a wireless receiver body, the wireless receiver body including a housing, a wireless receiving communication module, a second integrated circuit board, operation buttons, and a second battery compartment;

[0023] The wireless receiving and communication module is mounted on the second integrated circuit board, and the second integrated circuit board is connected to the display screen.

[0026] Optionally, the wireless receiver may be a standalone host or may be embedded in a gun-mounted ballistic computer used to emit the laser transverse beam.

[0027] This invention provides a remote zeroing system for photoelectric targets based on laser characteristics. By incorporating a laser sensing module, it can accurately sense the position and size of the laser spot, achieving high-precision target positioning and enabling rapid and accurate target zeroing over long distances. The system features a separate, independent design for the photoelectric target and the wireless receiver, with a wireless communication module enabling real-time wireless communication between them. This allows for timely transmission of laser sensing information to the wireless receiver, achieving fast and efficient data transmission. The photoelectric target itself has a compact, intelligent, layered design. The protective layer provides protection while ensuring normal laser transmission and minimizing light intensity loss.

Therefore, they should not be construed as limitations on this invention.

[0059] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0060] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0061] This invention provides, in one aspect, a remote zeroing system for photoelectric targets based on laser characteristics, such as... Figure 1 As shown, the system includes a photoelectric target and a wireless receiver, with the photoelectric target and the wireless receiver wirelessly connected; as Figure 2As shown, the photoelectric target includes a protective layer 1, a sensing layer 2, and a collection layer 3. The sensing layer 2 is located between the protective layer 1 and the collection layer 3. Multiple laser sensing modules 21 are arranged in a matrix on the sensing layer 2. A first integrated circuit board 32 is arranged on the collection layer 3, and a wireless communication module 33 is arranged on the first integrated circuit board 32. The multiple laser sensing modules 21 are connected to the first integrated circuit board 32. After the laser transverse film spot penetrates the protective layer 1, it reaches the sensing layer 2. The sensing layer 2 receives the laser transverse film spot through the multiple laser sensing modules 21 and generates laser sensing information, which is then transmitted to the collection layer 3. The collection layer 3 processes the laser sensing information through the first integrated circuit board 32 and transmits the processed laser sensing information to a wireless receiving device through the wireless communication module 33. The wireless receiving device analyzes and displays the processed laser sensing information.

[0062] The laser-based photoelectric target remote zeroing system provided by this invention can accurately sense the position and size of the laser spot by setting a laser sensing module 21, thereby achieving high-precision target positioning and rapid and accurate target zeroing over long distances. The system has a separate design for the photoelectric target and the wireless receiving device, and a real-time wireless communication connection between the photoelectric target and the wireless receiving device is achieved through a wireless communication module 33, which can transmit laser sensing information to the wireless receiving device in a timely manner, thereby achieving fast and efficient data transmission. The photoelectric target has a compact, intelligent, layered design. The protective layer 1 serves both as protection and ensures normal laser transmission, minimizing light intensity loss. The sensing layer 2 completes the sensing and monitoring of the entire laser spot, exhibiting strong adaptability and flexibility. The acquisition layer 3 provides important directional guidance for intelligent zeroing. The system provided by this application has the characteristics of high precision, real-time communication, safety protection, and flexibility, and can achieve accurate ranging and zeroing over long distances.

[0063] Specifically, in the above embodiments, such as Figure 3 As shown, the protective layer 1 is a light-transmitting film 11, and an aiming crosshair 12 is provided at the center of the light-transmitting film 11.

[0064] In this embodiment, the light-transmitting film 11 has a certain degree of light transmittance, which allows the laser beam to penetrate the protective layer 1 and reach the sensing layer 2. At the same time, it also allows the user to clearly see the aiming crosshair 12 and the target information when using it. Meanwhile, the light-transmitting film 11 also serves a protective function. The aiming crosshair 12 on the light-transmitting film 11 can guide the user to naturally align the aiming crosshair 12 with the center of the light-transmitting film 11 when aiming, thereby improving the aiming accuracy and allowing the user to hit the target more accurately.

[0065] Specifically, in the above embodiments, such as Figure 4As shown, the sensing layer 2 also includes a base plate and multiple light-blocking strips 22; the base plate is made of light-blocking material; the multiple light-blocking strips 22 are evenly distributed along the horizontal and vertical directions of the base plate, dividing the base plate into multiple closed sensing areas, and a laser sensing module 21 is set in each closed sensing area.

[0066] In this embodiment, the multiple light-blocking strips 22 on the base plate can block the propagation of light, preventing light from other areas from interfering with the operation of the laser sensing module 21, thus improving the accuracy and reliability of the system. The light-blocking strips 22 divide the base plate into multiple closed sensing areas, with one laser sensing module 21 set in each area. This allows for independent sensing and positioning of targets in different areas, unaffected by other areas, thereby improving the system's multi-target processing capability. Simultaneously, the design of the sensing layer 2 can be changed according to the different transverse mode laser beams received. By altering the geometry required for each independent closed sensing area, the overall beam pattern can be sensed and monitored, demonstrating strong adaptability and flexibility.

[0067] Furthermore, such as Figure 5 As shown, the laser sensing module 21 includes a laser receiving sensor 210, a mounting platform 211, and a data cable 212. The laser receiving sensor 210 is threadedly connected to the mounting platform 211, the bottom of the mounting platform 211 is set on the base plate, and the data cable 212 is set inside the mounting platform 211. One end of the data cable 212 is connected to the data cable interface of the laser receiving sensor 210, and the other end of the data cable 212 passes through the base plate and is connected to the first integrated circuit board 32 of the acquisition layer 3.

[0068] The laser receiver sensor 210 is a device used to receive and measure laser signals. It typically consists of a photodiode and related circuitry. When a laser beam passes through the laser receiver sensor 210, the photodiode converts the laser beam into an electrical signal, which is then processed by the circuitry to generate a corresponding output signal. The laser receiver sensor 210 is commonly used in laser ranging, photoelectric switches, laser navigation, obstacle avoidance systems, and other fields. It can accurately detect and measure parameters such as the intensity, position, and time of a laser beam. Depending on the specific application requirements, the laser receiver sensor 210 can employ different working principles and technologies, such as photodiodes, photomultiplier tubes, and fiber optic receivers.

[0069] In this embodiment, the laser sensing module 21 is connected to the mounting platform 211 via a thread, which ensures the stability and reliability of the laser sensor and makes it less susceptible to interference from external factors such as vibration, thereby improving the accuracy and reliability of the system. The data cable 212 is designed inside the mounting platform 211, which facilitates maintenance and replacement, thereby improving the maintainability and reliability of the system and reducing maintenance costs. The laser sensing module 21 is connected to the first integrated circuit board 32 of the acquisition layer 3 via the data cable 212, which makes data transmission simple and convenient, and also reduces the wiring cost and size of the system.

[0070] Specifically, in the above embodiments, such as Figure 6 As shown, the acquisition layer 3 also includes a second base plate, a first battery compartment 31, and a transmitting antenna 34; the first integrated circuit board 32 and the first battery compartment 31 are both disposed on the second base plate, the first battery compartment 31 is connected to the first integrated circuit board 32 and is used to power the first integrated circuit board 32; the transmitting antenna 34 is connected to the wireless communication module 33 on the first integrated circuit board 32 and extends out of the second base plate, and the wireless communication module 33 is wirelessly connected to the wireless receiving device through the transmitting antenna 34.

[0071] In this embodiment, the second base plate is made of a relatively robust material. The acquisition layer 3 can integrate and process the laser sensing information generated by the laser sensing module 21 on the sensing layer 2, and transmit the processed information in real time back to the wireless receiving device through the wireless module on the first integrated circuit board 32 and the transmitting antenna 34, providing an important directional guidance guarantee for intelligent zeroing.

[0072] Specifically, in the above embodiments, such as Figure 7 As shown, the photoelectric target also includes a fixed side frame 4 and a three-layer partition plate 41; the three-layer partition plate 41 is welded in parallel inside the fixed side frame 4, and the fixed side frame 4 is a rectangular side frame; the protective layer 1, the sensing layer 2 and the acquisition layer 3 are respectively threaded to a partition plate 41.

[0073] In this embodiment, by installing the fixed side frame 4, the various layers of the photoelectric target are organically installed into a whole, ensuring the stability and reliability of the overall structure of the photoelectric target, making it less susceptible to environmental vibration and external factors. All connections are completely sealed with adhesive strips or glue injection, so that the overall product can play a role in dustproofing, waterproofing and shock resistance during use. The partition plate 41 separates the protective layer 1, sensing layer 2 and acquisition layer 3 into independent layers, which is conducive to the separation and combination of each module, and at the same time improves the maintainability and operability of the system.

[0074] Specifically, in the above embodiments, such as Figure 8As shown, the wireless receiving device includes a display screen and a wireless receiver body. The wireless receiver body includes a housing, a wireless receiving communication module, a second integrated circuit board, operation buttons, and a second battery compartment. The wireless receiving communication module is mounted on the second integrated circuit board, which is connected to the display screen. The second battery compartment is connected to the second integrated circuit board and is used to power the second integrated circuit board. Both the second integrated circuit board and the second battery compartment are housed within the housing. The housing has operation buttons, which are connected to the second integrated circuit board and the wireless receiving communication module, respectively.

[0075] In this embodiment, the user can conveniently view and display the received wireless signal, as well as other relevant prompts and information, through the display screen. The display screen presents the data in a combination of graphics, letters, and arrows. The housing of the wireless receiver, the second integrated circuit board, and the second battery compartment are all installed together to form an independent device, which is easy to carry and move, allowing the user to use the wireless receiver in various environments. The operation buttons on the housing allow the user to perform convenient operation and control, and interact with the second integrated circuit board and the wireless receiving communication module. The second battery compartment ensures the normal operation of the entire wireless receiver.

[0076] Specifically, in the above embodiments, the wireless receiving device is either a standalone host or embedded in a gun-mounted ballistic computer used to emit laser transverse beams.

[0077] In this embodiment, when the wireless receiver is used as an independent host, it has independent functions and an operating interface, allowing users to use and control it freely and flexibly. However, embedding the wireless receiver into the gun-mounted ballistic computer enables an integrated design, simplifying the integration and portability of the device and improving ease of use. The data received by the wireless receiver can be transmitted to the gun-mounted ballistic computer through the wireless communication module, enabling real-time data transmission and processing. This provides faster and more accurate ballistic calculations, helping gun users better understand the shooting situation. By cooperating with the gun-mounted ballistic computer, the wireless receiver can provide more precise ballistic calculations. Considering the position of the laser transverse diaphragm spot and other key parameters, it helps improve shooting accuracy and hit rate, as well as long-range zeroing operations.

A side view of the photoelectric target is shown below. Figure 9 As shown.

[0084] 6. Design and manufacture the wireless receiving device, specifically including: designing and customizing the second integrated circuit board, the wireless receiving and communication module, integrating the wireless receiving and communication module into the second integrated circuit board as one unit, finally placing the relevant program into it, designing and customizing the casing, display screen, operation buttons, etc., and assembling them according to the design requirements to complete the overall manufacturing of the wireless receiving device.

[0085] 7.

[0086] 8. Conduct environmental tests such as waterproofing, aging, and shock resistance on the calibrated and adjusted products, and finally complete the finished product manufacturing.

[0087] Another aspect of the present invention provides a remote zeroing method for photoelectric targets based on laser characteristics. This method is applied to the aforementioned remote zeroing system for photoelectric targets based on laser characteristics, such as... Figure 10 As shown, the method includes first activating the ranging function of the gun-mounted ballistic computer or ranging module, and then emitting a laser transverse film spot to the aimed electro-optical target. Next, the acquisition layer 3 in the electro-optical target processes the laser sensing information generated by multiple laser sensing modules 21 in the electro-optical target based on the laser transverse film spot and sends it to the wireless receiving device. Finally, the wireless receiving device analyzes the processed laser sensing information, generates spot adjustment information, and adjusts the position of the laser transverse film spot emitted by the gun-mounted ballistic computer or ranging module based on the spot adjustment information until all multiple laser sensing modules 21 in the electro-optical target receive the laser transverse film spot, thus completing the process of remotely zeroing the electro-optical target.

[0088] The above method achieves a high degree of automation in the entire remote zeroing process of the photoelectric target through the automated control of the gun-mounted ballistic computer or ranging module, as well as the automatic processing, transmission and analysis of the acquisition layer 3 and the wireless receiving device, reducing operator intervention and operational errors; by generating precise spot adjustment information and continuously adjusting the spot, extremely high adjustment accuracy and speed are achieved, so that all the multiple laser sensing modules 21 in the photoelectric target receive the laser transverse film spot, and finally complete the remote zeroing of the photoelectric target with higher precision.

[0089] Furthermore, the processed laser sensing information is analyzed using a wireless receiving device to generate spot adjustment information. This includes: receiving the processed laser sensing information using a wireless receiving device and analyzing it to obtain analysis results; when the analysis results indicate that at least one laser sensing module 21 in the photoelectric target has not received the laser transverse film spot, obtaining the position information of at least one laser sensing module 21 in the photoelectric target; based on the position information of at least one laser sensing module 21 in the photoelectric target, determining the transverse adjustment information and longitudinal adjustment information of the laser transverse film spot on the photoelectric target, and integrating the transverse adjustment information and longitudinal adjustment information to generate spot adjustment information.

[0090] In this embodiment, the wireless receiving device can receive and process laser sensing information in real time, and obtain real-time analysis results through analysis. It can promptly understand whether there are any unreceived laser transverse beam spots in the photoelectric target and make corresponding adjustments. By acquiring the position information of at least one laser sensing module 21 in the photoelectric target, the specific location of the unreceived laser transverse beam spots can be determined. This helps to further analyze and locate the problem and provides an accurate benchmark for subsequent adjustments. Based on the position information of at least one laser sensing module 21 in the photoelectric target, the lateral and longitudinal adjustment information of the laser transverse beam spots on the photoelectric target can be calculated. After integrating these adjustment information to generate beam spot adjustment information, it can accurately guide the gun-mounted ballistic computer or ranging module to adjust the laser transverse beam spots, so as to ensure that all laser sensing modules 21 on the photoelectric target can receive the laser transverse beam spots.

[0091] Specific operations are as follows: Figure 11 As shown in the figure, there are a total of 9 closed sensing areas. Only the four areas in the lower right corner receive the laser transverse film spot. Therefore, the adjustment information generated is that the spot needs to be moved to the left by the distance of one closed sensing area, and then moved to the top by the distance of one closed sensing area, so that the laser transverse film spot can illuminate all the closed sensing areas, thus completing the adjustment process.

[0092] The specific operation procedure for zeroing using the laser-based photoelectric target remote zeroing method provided in this application is as follows: Figure 12 As shown, when the gun-mounted ballistic computer or rangefinder module is aimed at the crosshair target on the smart electro-optical target and the rangefinder function is activated, the invisible transverse mode laser spot emitted by it will illuminate the electro-optical target, such as... Figure 13 As shown, the laser receiving sensor 210 deployed on the photoelectric target will detect the appearance of the light spot in real time. At the same time, the first integrated circuit board 32 inside the photoelectric target will centrally process the laser sensing information and send it to the wireless receiving device in real time through the wireless communication module 33. The second integrated circuit in the wireless receiving device will centrally process the received data and display it in a combination of graphics, letters and arrows through the built-in program, informing users of the current status and the next adjustment prompt. Finally, the user will adjust the gun-mounted ballistic computer or ranging module according to the light spot adjustment information until the light spot completely covers the sensing layer 2, which is to complete a precise zeroing.

[0093] It should be noted that this application only uses commonly used laser rangefinders as an example. Their laser characteristics are generally wavelengths of 905nm or 1550nm, and the emitted laser is invisible. Its transverse mode is usually a TEM20 spot. The zeroing distance mentioned in this application can also be adjusted according to the size of the laser divergence angle. Generally, the smaller the divergence angle, the smaller the laser transverse mode spot, and the farther the zeroing distance; the larger the divergence angle, the larger the laser transverse mode spot, and the closer the zeroing distance. For other lasers, the zeroing distance can be adjusted according to their characteristics by adjusting the distance between the laser source, i.e., the distance between the gun-mounted ballistic computer or rangefinder module and the photoelectric target, and then judging and providing a readjustment scheme based on the data sent back by the photoelectric target. By repeating the operation a few times, the optimal zeroing distance suitable for the laser's own characteristics can be obtained. The laser beam divergence angle of existing gun-mounted laser rangefinders on the market is generally less than 2mard, so this distance usually exceeds 800 meters, hence it is called long distance.
