In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0030] In order to solve the technical bottlenecks of mechanical structure redundancy and high failure rate that are common in current basketball shooting machines, and in pursuit of versatility, the equipment often integrates multiple independent subsystems. The complex mechanical layout leads to crowded internal space and crisscrossing lines, which not only increases the difficulty of assembly and debugging, but also poses hidden dangers to later operation and maintenance.

[0031] In view of the above technical problems, various embodiments of the present case are described in detail below in conjunction with the accompanying drawings.

[0032] In some embodiments, Figure 1-2 As shown, a ball serving device 100 includes a motor (not shown), a frame 1, a driving gear 2, a ball dividing member 6, an ejection area 9 and an ejection member, and the driving gear 2, the ball dividing member 6, the ejection area 9 and the ejection member are respectively arranged on the frame 1; one end of the driving gear 2 is connected to the motor, and the driving gear 2 is provided with a hollow window surface 22; the ejection member includes a driven gear 3, a first connecting rod 42, an ejection rod 4 and a second connecting rod 7, the driven gear 3 is arranged opposite to the driving gear 2, the driven gear 3 and the ejection rod 4 are arranged on the first connecting rod 42, The first end of the ejection rod 4 is connected to the second connecting rod 7 through the first spring 5; the motor drives the active gear 2 to engage with the driven gear 3, and drives the driven gear 3 to rotate, the first connecting rod 42 and the ejection rod 4 cooperate with the driven gear 3 to rotate, pull the first spring 5 to produce elastic deformation, and the ejection rod 4 touches the ball dividing piece 6, the ball 8 on the ball dividing piece 6 falls into the ejection area 9, when the empty window surface 22 faces the driven gear 3, the engagement between the active gear 2 and the driven gear 3 fails, and the first spring 5 triggers the rebound potential energy to drive the ejection rod 4 to eject the ball 8.

[0033] In some implementations, the motor is fixedly connected to the driving gear 2, and the driving gear 2 is provided with a plurality of first gear teeth 21 and one or more hollow window surfaces 22. The hollow window surface 22 is formed by removing some gear teeth from the driving gear 2. The hollow window surface 22 is a region without gear teeth. The hollow window surface 22 can be an arc surface or a parallel surface, which is not limited here. The driving gear 2 is arranged opposite to the driven gear 3, and the driven gear 3 is provided with a plurality of second gear teeth 32. When the driving gear 2 rotates a preset number of circles, the first gear teeth 21 of the driving gear 2 mesh with the second gear teeth of the driven gear 3. It can be understood that the motor is fixedly connected to the driving gear 2 so that the driving gear 2 is driven to rotate when the motor is driven. When the driving gear 2 or the motor is damaged, the corresponding components can be selectively disassembled.

[0034] In some implementations, the driven gear 3 and the ejection rod 4 are respectively fixed on the first connecting rod 42. The rotation of the driven gear 3 can drive the first connecting rod 42 and the ejection rod 4 to work in conjunction. One end of the ejection rod 4 is connected to one end of the first spring 5, and the other end of the first spring 5 is connected to the second connecting rod 7.

[0035] In some implementations, the ball separator 6 is a mechanism for controlling the release of the ball 8, and the ball 8 is sent into the ejection area 9 one by one to prevent multiple balls 8 from falling at the same time or mistakenly entering the ejection area to cause blockage, jamming or ejection abnormality. The ejection area 9 is the positioning area of ​​the ball 8 before being ejected. After the ball 8 enters this area through the control of the ball separator 6, it will be in a predetermined position to ensure that the ball 8 can be accurately ejected when hit or pushed by the ejection rod 4. The ejection area 9 is generally provided with a guide structure or a limit groove to keep the ball 8 stable and immobile before ejection, so that the ball 8 can be accurately ejected.

[0036] In some implementations, the motor rotates a preset number of times, the driving gear 2 rotates in coordination, the driving gear 2 meshes with the driven gear 3, driving the driven gear 3 to rotate, the driven gear 3 drives the first connecting rod 42 and the ejection rod 4 to rotate, one end of the ejection rod 4 pulls the first spring 5 to produce elastic deformation, thereby accumulating rebound potential energy, during which the ejection rod 4 touches the ball dividing piece 6, and the ball 8 on the ball dividing piece 6 falls into the ejection area 9, when the empty window surface 22 of the driving gear 2 faces the driven gear 3, the first gear teeth 21 of the driving gear 2 are disengaged from the second gear teeth 32 of the driven gear 3, the driving gear 2 loses its limit on the driven gear 3, and the rebound potential energy accumulated by the first spring 5 is triggered, driving the ejection rod 4 to rotate toward the ball 8, ejecting the ball 8.

[0037] The driving gear 2 drives the driven gear 3 to drive the ejection rod 4 to eject the ball 8, and the first spring 5 resets the transmission structure. Only a single motor is needed to drive the driving gear 2 to complete the entire process of energy storage, release, and reset, avoiding complex transmission chains and redundant components. At the same time, the reset action is synchronized with the ball separation to achieve automatic continuous ejection, further improve the system's work efficiency and reliability, and achieve structural optimization and efficient operation while ensuring complete functions.

[0038] In some embodiments, Figure 1-2 As shown, the frame 1 is divided into an upper end, a middle end and a lower end. The upper end of the frame 1 is provided with an ejection area 9 and a ball dividing member 6, the middle end of the frame 1 is provided with a driving gear 2 and an ejection member, and the lower end of the frame 1 is provided with a second connecting rod 7.

[0039] In some implementations, an ejection area 9 and a ball separator 6 are provided at the upper end of the frame 1. This area is the part for positioning and ball separation, wherein the ball separator 6 is located above or in the middle of the ball 8 supply path, and is responsible for controlling the release of the balls 8 in sequence. After release, the balls 8 fall into the ejection area 9, which is the positioning area before the balls 8 are formally ejected, ensuring that the balls 8 are in the accurate ready-to-fire position. An active gear 2 and an ejection part are provided at the middle end of the frame 1. This area is the driving part of the entire ball serving device 100, ensuring that the ejection rod 4 can stably eject the balls 8 located in the ejection area 9. A second connecting rod 7 is provided at the lower end of the frame 1. This area is used for fixing and structural support of the first spring 5 and the second connecting rod 7, so that the first spring 5 remains stable during the energy storage and rebound process.

[0040] In some embodiments, Figure 3-5 As shown, the serving device 100 also includes a second spring 43, the ejection rod 4 is provided with a through structure 44 and a convex plate 41 arranged at one end of the ejection rod 4, the driven gear 3 is provided with a first push rod 31, and the first push rod 31 is movably arranged on the through structure 44; the driven gear 3 is connected to the convex plate 41 through the second spring 43, or the driven gear is connected to the frame through the second spring.

[0041] In some implementations, the ejection rod 4 is provided with a through structure 44 and a convex plate 41. The through structure 44 may be a long hole, a slide groove or a guide hole, and its function is to provide a guide path for the movement of the first push rod 31. The driven gear 3 is provided with a first push rod 31. The first push rod 31 may be a columnar or hook-shaped structure or other convex structure with sliding ability, one end of which is movably arranged on the through structure 44 of the ejection rod 4. When the driven gear 3 rotates, the first push rod 31 will move (slide or swing) along the through structure 44 of the ejection rod 4. One end of the second spring 43 is connected to the convex plate 41, and the other end of the second spring 43 is connected to the driven gear 3. The provision of the convex plate 41 can ensure that the second spring 43 is horizontally connected to the driven gear 3, thereby ensuring the force state and the stability of the structure.

[0042] In some implementations, one end of the second spring 43 in the ball serving device 100 is connected to the frame 1, and the other end is connected to the driven gear 3. One end of the second spring 43 is fixed to the frame 1, and the frame 1 is horizontally connected to the driven gear 3 through the second spring 43 to ensure the stress state and structural stability.

[0043] In some embodiments, Figure 3-5 As shown, the driven gear 3 drives the first push rod 31 to move, and when the first push rod 31 abuts against the end of the penetrating structure 44, the ejection rod 4 is driven to rotate.

[0044] In some implementations, the driven gear 3 drives the first push rod 31 to move during the rotation process. The first push rod 31 is arranged in the through structure 44 on the ejection rod 4. The first push rod 31 slides in the through structure 44 and does not immediately drive the ejection rod 4 to move. When the driven gear 3 continues to rotate and the first push rod 31 gradually moves to the end position of the through structure 44, the push rod 31 contacts the end of the through structure 44, and the first push rod 31 cannot continue to slide. Its rotational power begins to act on the ejection rod 4, thereby driving the ejection rod 4 to rotate. The problem of excessive impact force in the initial transmission of the ball serving device is solved. Once the driven gear 3 is engaged, it directly drives the ejection rod 4 to rotate, which may easily cause the first connecting rod 42 to break, deform or fatigue failure due to a sudden large torque. By arranging a through structure 44 on the ejection rod 4, the first push rod 31 only slides in the through structure 44 at the initial rotation of the driven gear 3, and does not apply direct rotational force to the ejection rod 4, thereby effectively buffering the impact force in the initial stage. When the first push rod 42 slides to the end position of the through structure 44, the ejection rod 4 is driven to rotate, realizing a smooth transition from sliding transmission to torsional transmission, thereby improving the mechanical reliability and service life of the ball serving device 100, and making the transmission process softer and smoother, thereby improving the service life and stability of the ball serving device.

[0045] In some implementations, the second spring 43 pulls the first push rod 31 to keep it at the top position of the through-structure 44. When the driving gear 2 drives the driven gear 3 to rotate, the pulling force of the second spring 43 causes the first push rod 31 to slide in the through-structure 44 first. After the first push rod 31 gradually slides to the end position of the through-structure 44, it no longer continues to slide, and the rotational force begins to act directly on the ejection rod 4. When the driving gear 2 is disengaged from the driven gear 3, the second spring 43 releases the stored rebound potential energy and resets the first push rod 31 to the top position of the through-structure 44, ensuring that the first connecting rod 42 can be effectively buffered each time the driving gear 2 drives the driven gear 3.

[0046] Need to explain, such as Figure 4 As shown, the top position refers to the initial position of the first push rod 31 under the tension of the second spring 43, as shown in FIG. Figure 5 As shown, the end of the through-structure 44 refers to the extreme end point that the first push rod 31 can reach when moving in the through-structure 44. When the first push rod 31 slides to the end position, there is no longer space for further sliding, and its subsequent rotational power begins to directly act on the ejection rod 4, driving the ejection rod 4 to rotate.

[0047] In some embodiments, Figure 6As shown, the ball dividing piece 6 includes a bearing block 62, which is provided with a second push rod 63; a sliding mechanism 64, which is located below the bearing block 62; a third connecting rod 61, and the bearing block 62 and the sliding mechanism 64 are respectively movably connected to the third connecting rod 61; when the ejection rod 4 touches the ball dividing piece 6, the ejection rod 4 pushes the sliding mechanism 64, the sliding mechanism 64 resists the second push rod 63, and the bearing block 62 rotates to place the next ball 8 into the ejection area 9.

[0048] In some implementations, such as Figure 6 As shown, the ball-distributing member 6 comprises a bearing block 62, a sliding mechanism 64 and a third connecting rod 61, and the bearing block 62 and the sliding mechanism 64 are respectively movably connected to the third connecting rod 61. The bearing block 62 is used to carry and position the ball 8, the sliding mechanism 64 is located below the bearing block 62, and is used to drive the trigger mechanism of the ball-distributing action, and the third connecting rod 61 plays the role of connection and rotation support, so that the bearing block 62 and the sliding mechanism 64 can rotate around the third connecting rod 61. In addition, a second push rod 63 is provided on the bearing block 62, which is used to receive the top pressure from the sliding mechanism 64 during the ball-distributing process, thereby triggering the tilting or rotation action of the bearing block 62 to achieve the release of the ball.

[0049] It should be noted that the setting position of the second push rod 63 is not fixed and can be set at any position of the supporting block 62, as long as the sliding mechanism 64 can contact the second push rod 63 during the movement and generate sufficient pushing pressure to drive the supporting block 62 to rotate or tilt, so that the ball 8 is released from the supporting block 62 to the ejection area 9.

[0050] In some implementations, the driven gear 3 drives the first connecting rod 42 and the ejection rod 4 to rotate to stretch the first spring 5. The ejection rod 4 pushes the sliding mechanism 64 to move during the movement. The sliding mechanism 64 presses the top rod 63 on the bearing block 62, so that the bearing block 62 tilts or rotates with the cooperation of the third connecting rod 61, and the carried ball 8 is placed in the ejection area 9. Through this structural design, the ejection action and the ball distribution action are linked, which ensures the synchronization of the actions and improves the stability and automation efficiency of the ball serving device 100.

[0051] In some embodiments, Figure 7 As shown, the ball dividing member 6 also includes a locking pin 65 and a third spring 66. The locking pin 65 is located below the supporting block 62, and the supporting block 62 is connected to the frame 1 through the third spring 66; the ejection rod 4 pushes the sliding mechanism 64, pulling the third spring 66 to produce elastic deformation, the ejection rod 4 is separated from the sliding mechanism 64, and the rebound potential energy of the third spring 66 drives the supporting block 62 to rotate, and the locking pin 65 presses against the supporting block 62.

[0052] In some implementations, the ball dividing member 6 also includes a locking pin 65 and a third spring 66. The locking pin 65 is arranged below the supporting block 62. One end of the third spring 66 is connected to the supporting block 62, and the other end is connected to the frame 1. The third spring 66 is used to pull the supporting block 62 to maintain the state of receiving the ball 8. The locking pin 65 is used to lock the supporting block 62 to prevent the third spring 66 from pulling the supporting block 62 to excessively move, so that the supporting block 62 cannot receive the ball 8 when the ball 8 falls.

[0053] It should be noted that the frame 8 may be provided with a fixed rod, and the third spring 66 may be connected to the frame 8 or connected to a fixed rod provided on the frame 8 .

[0054] In some implementations, the sliding mechanism 64 contacts the second push rod 63 on the supporting block 62 during movement and generates a push pressure, causing the supporting block 62 to rotate under the action of the push pressure, thereby releasing the ball to fall into the ejection area 9 and completing the ball distribution action. At the same time, the rotational movement of the sliding mechanism 64 will also pull the third spring 66 connected to the supporting block 62, causing it to produce elastic deformation and store rebound potential energy. When the ejection rod 4 is separated from the sliding mechanism 64, the third spring 66 begins to release the rebound force, driving the supporting block 62 to rotate to the initial position to restore the receiving state. The locking pin 65 limits and supports the supporting block 62 to prevent it from deflecting or shaking due to excessive rebound of the third spring 66, thereby ensuring that the supporting block 62 is stably positioned and that the subsequent ball is smoothly received.

[0055] In some embodiments, the launching device 100 also includes a fixed rod 11 and a telescopic mechanism 10, and the fixed rod 11 is arranged on the frame 1; the second connecting rod 7 is movably connected to the fixed rod 11, and the second end of the second connecting rod 7 is connected to the telescopic structure 10; the telescopic mechanism 10 adjusts the telescopic length, drives the second connecting rod 7 to rotate on the fixed rod 11, and adjusts the length of the first spring 5 to adjust the serving force.

[0056] In some implementations, the serving device 100 also includes a fixed rod 11 and a telescopic mechanism 10. The fixed rod 11 is installed on the frame 1. The second connecting rod 7 is movably connected to the fixed rod 11, that is, it rotates around the fixed rod 11. The second end of the second connecting rod 7 is connected to the telescopic mechanism 10. The telescopic mechanism 10 can be a spiral push rod, a gas spring, a slide rail assembly or other structural components with adjustable length, which is used to adjust the rotation of the second connecting rod 7 to adjust the length of the first spring 5, thereby adjusting the serving force.

[0057] It should be noted that the first end of the second connecting rod 7 is an end connected to the ejection rod 4 , and the second end of the second connecting rod is an end connected to the telescopic mechanism 10 .

[0058] In some implementations, the telescopic mechanism 10 drives the second connecting rod 7 connected thereto to move by changing its own length, so that the second connecting rod 7 rotates with the connection point between the second connecting rod 7 and the fixed rod 11 as the rotation center. The rotation change of the second connecting rod 7 affects the length of the first spring 5, so that the rebound potential energy of the first spring 5 drives the potential energy of the ejection rod 4 to rotate, thereby adjusting the serving strength. For example, when the telescopic mechanism 10 is elongated, the rotation angle of the second connecting rod 7 increases, the spring preload increases, the rebound potential energy generated is enhanced, and the serving strength of the ejection rod 4 increases; conversely, when the telescopic mechanism 10 is shortened, the angle of the second connecting rod 7 decreases, the rebound potential energy generated is reduced, and the serving strength of the ejection rod 4 decreases. Users can quickly adjust the serving strength according to actual use needs to adapt to the serving requirements of different distances or scenes, thereby improving the practicality and ease of operation of the device, and no complex electronic control or multi-stage transmission system is required. The overall design is compact, easy to assemble and maintain, and effectively reduces the manufacturing cost and failure rate.

[0059] In some embodiments, the serving device 100 further includes a rotating mechanism (not shown), and the rotating mechanism and the motor are linked by a fixed connection or a transmission device (such as a gear set, a coupling or a belt drive). After the motor is started, the output shaft drives the gear to rotate, and then transmits power to the rotating mechanism through the transmission mechanism, so that the rotating mechanism rotates at a preset angle and speed. The rotating mechanism can be designed as a disc or a rotating arm to rotate the launching device 100 to a preset position, thereby meeting the requirements of different serving angles, and achieving a simple structure, easy assembly and maintenance.

[0060] In some embodiments, a shooting system 200 is also disclosed. The shooting system 200 includes a control unit 210, which is used to receive a target instruction; a launching unit 220, which is used to launch a sphere 8; a strength adjustment unit 230, which is used to adjust the serving strength of the launching unit 220. Based on the target instruction, the strength adjustment unit 230 adjusts the serving strength of the launching unit 220; a rotation unit 240, which is used to rotate the serving angle of the launching unit 220. Based on the target instruction, the rotation unit 240 adjusts the serving angle of the launching unit 220; based on the target instruction, the launching unit 220 sends the sphere 8 to the target position.

[0061] In some implementations, the control unit 210 is used to receive target instructions input by the user, including parameter information such as launch force, launch angle, and shooting target position. The control unit 210 can be a microprocessor, an embedded system, a PLC, or other control device with logic control capabilities, and communicate data and interact with other units for control signals. The launch unit 220 is used to launch the sphere 8 from the launch area to the target position. The launch unit 220 includes a mechanical ejection structure, an electric propulsion mechanism, a pneumatic launch mechanism, or other forms of power launch mechanisms to output launch kinetic energy. The launch unit 220 can be arranged on a rotatable platform to achieve multi-angle launch. The force adjustment unit 230 is linked with the launch unit 220 to adjust the output force of the launch unit 220. The force adjustment unit 230 includes a spring preload adjustment structure, a motor pressure adjustment structure, a pneumatic or hydraulic adjustment device, etc. The control unit 210 controls the force adjustment unit 230 to change the output energy of the launch unit 220 according to the target instruction, thereby accurately controlling the flight distance and speed of the sphere 8. The rotating unit 240 is connected to the launching unit 220 and is used to adjust the serving angle of the launching unit 220. The rotating unit 240 may include a rotating motor, a speed reduction mechanism, a rotating bracket and other components to achieve horizontal or vertical angle adjustment. The control unit 210 controls the rotating unit 240 according to the target position instruction to ensure that the launching unit 220 is aligned with the target position.

[0062] In some implementations, the user inputs a target instruction through a human-computer interaction interface or a control terminal. After the control unit 210 receives and parses the target instruction, it sends control signals to the force adjustment unit 230 and the rotation unit 240 respectively. The force adjustment unit 230 adjusts the elastic force or power output strength of the launch element according to the instruction, thereby setting a suitable launch force; at the same time, the rotation unit 240 adjusts the direction of the launch unit 220 according to the target instruction setting angle so that it is aligned with the target shooting position. After the force and angle are adjusted, the control unit 210 controls the launch unit 220 to start the serve action and accurately launch the ball 8 to the target position. The entire system can automatically complete the adjustment and launch process, realizing intelligent, high-precision shooting training or entertainment experience.

[0063] In some implementations, the shooting system 200 also includes: a positioning unit 250, which is used to locate the target user. Based on the target instruction, the positioning unit 250 locates the target user and obtains positioning information. According to the positioning information, the rotation unit 240 and the force adjustment unit 230 are adjusted so that the launching unit 220 shoots the ball 8 to the target position.

[0064] In some implementations, the positioning unit 250 may include any one or more combinations of infrared sensors, ultrasonic sensors, camera modules, radar modules, laser rangefinders, visual recognition systems, UWB modules, RFID, etc., for obtaining the location information of the target user in space. The positioning unit 250 is in communication with the control unit 210, and is used to identify and track the location of the target user in real time based on the user positioning requirements in the target instructions, and obtain the user's spatial coordinates or relative orientation and other positioning information. After receiving the positioning information provided by the positioning unit 250, the control unit 210 can calculate the launch path according to the positioning information and automatically control the rotation unit 240 and the strength adjustment unit 230 to adjust the angle and strength respectively, thereby achieving precise directional serve.

[0065] In some implementations, the control unit 210 first receives a target instruction from a user, and the positioning unit 250 starts working under the instruction of the control unit 210, obtains the position data of the target user in real time through sensor recognition, image processing or spatial ranging, and sends the positioning information to the control unit 210. The control unit 210 performs path calculation and angle parameter analysis based on the positioning information, controls the rotation unit 240 to automatically adjust the serving angle of the launch unit 220 so that the serving direction is toward the target user; at the same time, the strength adjustment unit 230 is controlled to adjust the launch strength so that the ball 8 can accurately reach the location of the target user. After the adjustment is completed, the control unit 210 issues a launch instruction, and the launch unit 220 accurately shoots the ball 8 to the user's location, completing the intelligent and automated fixed-point shooting service process.

[0066] In some embodiments, the control unit 210 is preset with target position parameters. Based on the user's target instructions, the control unit 210 controls the rotation unit 240 and the strength adjustment unit 230 to automatically adjust the serve direction and serve strength according to the preset target position parameters, so that the launch unit 220 can accurately deliver the ball 8 to one or more designated positions. For example, the launch unit 220 quickly serves the ball 8 to the three-point line, the bottom corner area, the mid-range area or the basket position to train the reaction of catching and shooting and the coordination of running positions, thereby creating a training environment that is closer to actual combat. It can not only be used for personal fixed-point training, but also can be combined with multi-point transformation mode for continuous serving, so as to realize diversified exercises such as running and catching the ball, catching and shooting, and turning and shooting.

[0067] In some embodiments, the user or the system may pre-set one or more target position parameters. Based on the user operation, the control unit 210 controls the rotation unit 240 and the strength adjustment unit 230 to automatically adjust the serving direction and serving strength according to the preset target position parameters, so that the launch unit 220 can accurately deliver the ball 8 to the designated area. For example, the user is allowed to set one or more sets of training shooting points through the system (smart devices such as mobile phones and tablets), such as multiple angle positions outside the three-point line (such as 0°, 45°, 90°, 135°, 180°), and each point can be set with a specific number of shots (such as 5 times per point). The control unit 210 completes the serving tasks of the corresponding points in sequence according to the set order. The control unit 210 converts the user's target position parameters into serving angle and strength parameters, automatically controls the rotation unit 240 and the strength adjustment unit 230, and drives the launch unit 220 to accurately deliver the ball 8 to the user, thereby helping the player to perform fixed-point, high-intensity shooting training.

[0068] In some embodiments, the shooting system 200 also includes: a voice unit; based on the target instruction, the positioning unit 250 locates the shooting gesture of the target user; obtains the shooting gesture data from the database, compares and analyzes the user's shooting gesture with the shooting gesture data in the database, and obtains a judgment result; if the judgment is inconsistent, then according to the judgment result, a gesture-adjusted voice is issued and / or the user's shooting gesture and the judgment result analysis data are recorded and output to the system of the target user.

[0069] In some implementations, the control unit 210 drives the positioning unit 250 based on the target instruction, tracks the target user's movements, and obtains the user's shooting gesture information during the shooting process, including but not limited to hand release trajectory, arm swing amplitude, wrist flip angle, knee joint bending angle and other posture parameters. The standard gesture data is pre-stored in the database, and the control unit 210 obtains the data model of the standard shooting gesture from the database, which includes one or more typical shooting gestures and their corresponding parameters that meet the technical action specifications. The control unit 210 compares and analyzes the gesture information obtained by the user in real time with the standard gesture data, and generates an action determination result through a similarity determination algorithm. When there is a significant deviation between the user's gesture and the standard database gesture data, the control unit 210 obtains an inconsistent determination result, and the system calls the voice unit according to the specific dimension of the deviation, and outputs the corresponding voice prompt information, such as "low wrist angle", "too late release point", "irregular shooting action", etc., to assist the user in correcting the action. At the same time, the control unit 210 can also store the user's current shooting action data, the process data compared with the standard gesture analysis, and the judgment results, and output them to the target user's system for the user to view the training feedback report or conduct subsequent data analysis and training optimization. Based on the judgment results of the control unit 210, the voice unit can provide instant feedback, prompt action problems at the first time, and assist the user in forming the correct technical path. In addition, the data during the training process of the target user can be recorded and analyzed by the control unit 210 to form a personalized shooting training file, which is output to the target user's system to facilitate the subsequent optimization of training strategies and further improve training efficiency and action standardization.

[0070] In some embodiments, the positioning unit 250 includes a shooting device 251 and a monitoring device 252, the shooting device 251 is used to locate the target user, and the monitoring device 252 is used to locate the target user and monitor the preset position; the positioning unit 250 receives a target instruction, the shooting device 251 locates the target user, and the monitoring device 252 switches the monitoring preset position to locating the target user, and obtains the positioning information according to the first shooting data of the shooting device 251 and the second shooting data of the monitoring device 252.

[0071] In some implementations, the shooting device 251 is provided on the shooting system 200, and is used to capture the image information of the target user at a close distance. The monitoring device 252 is provided around or at a high place in the training area, and has a wide-angle field of view and environmental monitoring functions, and is used to monitor the activities of people around and environmental changes in real time and capture the position of the target user. When the shooting system 200 is started, the control unit 210 activates the positioning unit 250 based on the target instruction. First, the shooting system 200 establishes a data connection with the monitoring device 252 through a wireless connection (such as a WIFI communication protocol or a Bluetooth communication protocol) to achieve information exchange. The control unit 210 sends a task instruction to the monitoring device 252, instructing the monitoring device 252 to switch from the monitoring mode to locate the position of the target user, and cooperate with the shooting device 251 to track and identify the target user. The shooting device 251 or the monitoring device 252 determines the target user based on the preset action of the target user, and transmits it to the control unit 210. The control unit 210 fuses the first shooting data with the second shooting data to obtain more accurate positioning information.

[0072] In one embodiment, based on the target instruction, the control unit 210 drives the shooting device 251 to obtain the first shooting data, which includes the shooting action posture, hand posture, shooting angle, body posture, motion trajectory, etc., and can capture and analyze the user's training action at a detailed level. The control unit 210 drives the monitoring device 252 to obtain the second shooting data, which includes the overall position coordinates of the target user, the spatial distance between the user and the serving device 100, the identification information of the training area, the user's movement trajectory, the shooting point identification information, and the environmental background image, etc. Through the second shooting data collected by the monitoring device 252, the shooting system 200 can realize the real-time position perception of the user in the training field, and combine the action analysis results of the shooting device 251 to form complete user positioning information, further improve the comprehensive positioning effect of the target user, and ensure that the serving angle and strength adjustment are more accurate.

[0073] In one embodiment, the target instruction refers to a control signal issued by the user's system (such as a user terminal, a training management platform, a mobile application, etc.), and received by the control unit 210 in the shooting system 200. The target instruction may include specific requirements for the serving action, such as serving strength, serving angle, serving position, training rhythm, serving frequency and other parameter settings, and may also include user position positioning, shooting gesture recognition, training mode switching, voice / gesture interactive response and other functional instructions. After receiving the target instruction, the control unit 210 coordinates and controls the various functional modules (such as strength adjustment unit, rotation unit, launch unit, positioning unit, etc.) inside the system to perform corresponding actions, so that the serving process accurately matches the user's training needs. Through the setting and control of the target instruction, the intelligent operation and highly personalized training effect of the shooting system 200 are realized, thereby significantly improving the practicality of the system and the human-computer interaction experience.
