The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0019] See also Figure 1 and Figure 2 , which is a structural schematic diagram of an intelligent ball serving mechanism provided in an embodiment of the present application, and may specifically include: a base (1), a turntable (2), a pan / tilt bracket (3), a pitch rotation axis (4), a supporting device (5), a rotating launch cabin (6) and a ball-docking pipe (7); The turntable (2) is arranged on the base (1), and is used to drive the pan / tilt bracket (3) to move circumferentially relative to the base (1), so as to drive the rotating launch cabin (6) to move circumferentially; The pitch rotation axis (4) is connected to the gimbal bracket (3) and the support device (5), and the pitch rotation axis (4) is used to drive the support device (5) to perform a pitch operation relative to the gimbal bracket (3), so as to drive the rotating launch cabin (6) to perform a pitch operation; The rotating launching cabin (6) is fixed above the supporting device (5); The goal pipe (7) is arranged above the rotating launching cabin (6), and the goal pipe (7) is in communication with the rotating launching cabin (6).

[0020] Exemplarily, the base (1) is the supporting platform of the entire ball-serving mechanism, which provides a stable foundation for other components. All mechanical movements rely on the base as a fixed support to ensure the stability of the ball-serving mechanism and the accuracy of operation.

[0021] The turntable (2) is located on the base (1), and through its rotation, drives the pan-tilt bracket (3) to move in a circumferential direction relative to the base. The rotation function of the turntable (2) enables the pan-tilt bracket to rotate in a horizontal plane, thereby achieving circumferential movement of the rotating launch cabin (6). This movement ensures the diversity of the launch angle, so that the launch mechanism can adjust the angle of the launch port according to needs.

[0022] The pan-tilt bracket (3) is a key part above the turntable (2). It can realize circumferential movement around the base by connecting with the turntable. The pan-tilt bracket (3) not only supports the rotating launch cabin (6), but also cooperates with other components to realize the pitch movement of the rotating launch cabin. The rotation of the pan-tilt bracket allows the launch port (8) to be adjusted in the horizontal plane to meet different serving requirements.

[0023] The pitch rotation axis (4) connects the pan / tilt bracket (3) and the support device (5), and its main function is to drive the support device (5) to perform pitch motion, that is, to swing up and down around the horizontal axis. This motion enables the rotating launch cabin (6) to be adjusted in the vertical direction, thereby controlling the up and down angle of the launch port (8). By adjusting the pitch angle, it can be ensured that the launched sphere is launched within different angle ranges.

[0024] The support device (5) is located below the pitch rotation axis (4) and fixedly supports the rotating launch cabin (6). By connecting with the pitch rotation axis (4), the support device (5) allows the rotating launch cabin to perform pitch movement, thereby achieving up and down adjustment of the launch port. The support device stabilizes the rotating launch cabin and supports the entire structure, thereby ensuring the stability of the serving process.

[0025] The rotating launch cabin (6) is the core component of the entire launching mechanism, which is responsible for receiving the ball to be launched and completing the launching of the ball through mechanisms such as the hammer (10). The rotating launch cabin (6) is fixed on top of it through the supporting device (5), and with the help of the pan-tilt bracket and the pitch rotation axis, it can realize free adjustment of the circumference and pitch, and can accurately adjust the launching angle according to different needs.

[0026] The goal pipe (7) is arranged above the rotating launch cabin (6) and is in communication with the rotating launch cabin (6), and is mainly used to guide the sphere to the rotating launch cabin (6). Through the goal pipe (7), the sphere to be launched can smoothly enter the rotating launch cabin (6) and be ready for launch.

[0027] In summary, most of the existing ball machines can only launch specific types of balls. For example, different ball machines need to be purchased for different types of balls such as table tennis and tennis. In contrast, the intelligent ball serving mechanism proposed in this application can support the launch of multiple balls through flexible mechanical design. By adjusting the circumferential and pitch angles of the rotating launch cabin, the launch angle and speed can be adjusted according to the characteristics of different balls, which greatly improves the versatility and adaptability of the ball machine, so that users can meet the training needs of multiple balls without purchasing multiple devices, reducing expenses. The method proposed in this application realizes the precise control of the rotating launch cabin by driving the rotation of the pan-tilt bracket through the turntable and driving the pitch adjustment of the support device through the pitch rotation axis. Both the pitch angle (up and down adjustment) and the horizontal angle (circumferential adjustment) of the serve can be precisely adjusted through the mechanical structure, thereby realizing multi-angle serve. Compared with the traditional manual or fixed angle adjustment ball machine, this adjustment method can provide more flexible and diverse serve options to meet the needs of different training and entertainment. Through flexible serve angle adjustment and efficient mechanical coordination, our application can provide users with a variety of serve modes, which is especially important during training. Whether it is to provide precise training for high-level players in sports such as table tennis and tennis, or to provide ordinary enthusiasts with highly entertaining serve modes, it can effectively improve the training effect and entertainment fun.

[0028] In a feasible embodiment, the rotating launch cabin (6) comprises a launch port (8), a fixed slide rail (9), a striker (10), a cantilever (11), a cantilever accelerator (12) and an airflow nozzle (13); The rotating launching chamber (6) is connected to the launching port (8); the goal pipe (7) is located above the connecting point between the launching port (8) and the rotating launching chamber (6), and the goal pipe (7) is connected to the launching port (8); the fixed slide rail (9) is arranged inside the launching port (8); the cantilever accelerator (12) is arranged at the center of the rotating launching chamber (6); the cantilever (11) is fixed on the cantilever accelerator (12), and the hammer (10) is fixed at the rear end of the cantilever (11); the airflow nozzles (13) are arranged in a centrally symmetrical manner inside the launching port (8).

[0029] Exemplarily, the launch port (8) is the main exit of the rotating launch chamber (6), and the ball is launched from here after being processed by various components inside the rotating launch chamber. The launch port is the end point of the entire serving process, and the ball enters the external trajectory from here to complete the serving action. The design of the launch port not only needs to ensure that the ball passes smoothly, but also can adapt to different launch angles and speed adjustments.

[0030] The fixed slide rail (9) is arranged inside the launch port (8) to provide a precise guide channel for the ball to be launched. The ball is positioned at the launch port along the slide rail to ensure that the ball can enter the correct position and be ready for launch. The slide rail can prevent the ball from deflecting or getting stuck, thereby ensuring the accuracy and smoothness of each launch.

[0031] The striker (10) is a key component for launching the ball in the rotating launch chamber and is located at the tail end of the cantilever (11). The striker obtains strong kinetic energy by cooperating with the cantilever (11) and strikes the ball, thereby completing the launch action. The striker needs to have a high speed and strength to ensure that the ball is effectively launched at different angles and speeds.

[0032] The cantilever (11) is a supporting structure fixed on the cantilever accelerator (12) and serves as a power transmission device. The main function of the cantilever is to transmit the kinetic energy provided by the cantilever accelerator (12) to the hammer (10), so that the hammer can quickly exert force to launch the ball. The design of the cantilever makes the movement of the hammer more stable and helps to ensure the stability and consistency of the serve.

[0033] The cantilever accelerator (12) is arranged at the center of the rotating launch cabin (6) as a core part for providing power. The cantilever accelerator provides the necessary impact energy for the hammer (10) by accelerating the movement of the cantilever (11). The efficient acceleration performance of the cantilever accelerator can ensure that the hammer quickly obtains sufficient kinetic energy, thereby achieving high-speed and high-force serving.

[0034] The airflow nozzle (13) is arranged inside the launch port (8) and is arranged in a central symmetrical manner. The airflow nozzle is used to push the ball through the launch port and accelerate the launch process of the ball. The airflow nozzle not only helps to reduce friction, but also increases the launch speed of the ball. The design of the airflow nozzle makes the launch process smoother and avoids the ball from getting stuck or irregularly deviating during the launch process.

[0035] The goal pipe (7) is located between the launch port (8) and the rotating launch chamber (6) and is responsible for delivering the ball to be launched from the outside into the rotating launch chamber. The goal pipe ensures that the ball can enter the launch chamber accurately and smoothly, ready for the next launch. It is a key part of the ball transportation channel and ensures the continuity and smoothness of the serve.

[0036] By rationally configuring and designing the fixed rail (9), the hammer (10), the cantilever (11), the cantilever accelerator (12) and the airflow nozzle (13) components, an efficient and accurate ball serving system is formed. These components cooperate with each other to achieve stable transmission, acceleration and launch of the ball in the rotating launch chamber (6), ensuring that the ball can be launched at a predetermined speed and angle to meet various different ball serving requirements. Through this design, the ball serving machine can efficiently complete the ball serving process, can ensure the accuracy of the ball serving, and can provide a high ball serving speed and stability, and can be used in a variety of occasions. In a feasible implementation manner, the turntable (2) comprises a horizontal angle controller (15), and the horizontal angle controller (15) is used to control the circumferential rotation angle of the turntable (2).

[0037] For example, the turntable (2) is located on the base (1), and its main function is to drive the pan / tilt bracket (3) to rotate circumferentially relative to the base, thereby driving the rotating launch cabin (6) to achieve circumferential movement. The rotation of the turntable is the basis for the serving mechanism to achieve the change of the serving angle. Through the rotation of the turntable, the entire serving mechanism can adjust the launching angle in the horizontal plane, thereby achieving a variety of serving modes.

[0038] The horizontal angle controller (15) is a key component disposed on the turntable (2), and is mainly used to control the circumferential rotation angle of the turntable. It can accurately adjust the rotation angle of the turntable, thereby adjusting the relative position and movement direction of the pan / tilt bracket (3) and the rotating launch cabin (6). By adjusting the rotation angle of the turntable, the horizontal angle controller (15) ensures that the serving mechanism can accurately adjust the direction and angle of the launch port according to requirements. The function of the horizontal angle controller is to enable the rotating launch cabin (6) to be adjusted to a specified angle along the horizontal plane through precise control of the turntable. Users can flexibly adjust the launch angle according to different serving requirements to achieve different serving strategies.

[0039] By introducing the horizontal angle controller (15), the turntable (2) has the ability to precisely adjust the angle, so that the serving mechanism can achieve flexible horizontal angle adjustment. This not only improves the functionality and adaptability of the serving mechanism, but also increases the user's selectivity in sports, and can adjust the launching angle according to different needs, thereby achieving more efficient and more accurate serving.

[0040] In a feasible implementation manner, the pitch rotation axis (4) comprises a pitch angle controller (16), and the pitch angle controller (16) is used to control the rotation angle of the pitch rotation axis (4); The cantilever accelerator (12) comprises a drive system (19) and a speed controller (17); the cantilever (11) is in transmission connection with the drive system (19); and the speed controller (17) is used to control the rotation speed of the cantilever (11).

[0041] Exemplarily, the pitch rotation axis (4) is connected to the gimbal bracket (3) and the support device (5), and is used to drive the support device (5) to perform a pitch movement around a horizontal axis, thereby adjusting the up and down angle of the rotating launch cabin (6). The pitch angle controller (16) is configured to control the rotation angle of the pitch rotation axis (4). By accurately controlling the movement of the pitch rotation axis, the pitch angle controller (16) can accurately adjust the up and down angle of the rotating launch cabin (6), thereby ensuring that the launch angle of the serving port can be adjusted as needed. By adjusting the pitch angle controller (16), the angle of the pitch rotation axis (4) can be accurately controlled, so that the rotating launch cabin (6) can be finely adjusted in the vertical direction.

[0042] The cantilever accelerator (12) is located at the center of the rotating launch cabin (6) and works in conjunction with the cantilever (11) and the striker (10). The cantilever (11) is connected to the cantilever accelerator (12) so that the striker (10) can generate sufficient power to strike and launch the ball.

[0043] The drive system (19) is a part of the cantilever accelerator (12) and is responsible for driving the cantilever (11) to rotate. The drive system (19) provides a power source for the cantilever, allowing the cantilever to move at high speed, thereby driving the hammer (10) to generate a launching force. Through the efficient drive system, it is ensured that the cantilever (11) can achieve high-speed rotation and transfer kinetic energy to the hammer (10), ensuring that the ball can be launched at the required speed and force. The drive system not only ensures the accuracy of the launch, but also can improve the speed and force of the serve, thereby adapting to the serving requirements in different sports.

[0044] The speed controller (17) cooperates with the drive system (19) to control the rotation speed of the cantilever (11). By adjusting the rotation speed, the speed controller (17) can finely adjust the rotation speed of the cantilever (11), thereby achieving control of the force and speed of the hammer (10). Through the speed controller (17), the user can adjust the rotation speed of the cantilever (11), thereby adjusting the force and speed of the serve. This allows the serving mechanism to adapt to different training requirements, such as fast serve or slow serve. By accurately controlling the rotation speed, the stability and consistency of the serve can be ensured, especially in training to meet different ball speed requirements.

[0045] By introducing the pitch angle controller (16) and the driving system (19) and the speed controller (17) in the cantilever accelerator (12), the pitch angle of the pitch rotation axis (4) and the rotation speed of the cantilever (11) are respectively precisely controlled. This enables the entire serving mechanism to have higher flexibility and accuracy in terms of the launching angle and serving force, and can be quickly adjusted according to user needs, greatly improving the diversity and adaptability of serving.

[0046] In a feasible embodiment, the cantilever accelerator (12) comprises a braking system (20) and a braking controller (18), the cantilever (11) is connected to the braking system (20), and the braking controller (18) is used to control the deceleration rate of the cantilever (11); The airflow nozzle (13) comprises a nozzle controller (21), and the nozzle controller (21) is used to control the size and direction of the airflow ejected from the airflow nozzle (13).

[0047] Exemplarily, the movable cantilever (11) rotates to drive the hammer (10) to generate kinetic energy, thereby launching the ball. The braking system (20) is connected to the cantilever (11) to control the deceleration of the cantilever rotation. When the cantilever (11) completes the serving action, the braking system (20) gradually reduces the rotation speed of the cantilever by applying a braking force, thereby smoothly stopping the movement of the cantilever. By reducing the rotation speed of the cantilever (11), the braking system (20) can avoid the impact of stopping too quickly on the system, while ensuring the smooth progress of the serving action.

[0048] The brake controller (18) is used to control the deceleration rate of the brake system (20). By adjusting the deceleration rate, the brake controller (18) ensures that the cantilever (11) can stop moving smoothly and quickly, avoiding excessive deceleration or delayed deceleration. The brake controller (18) can finely control the deceleration process of the cantilever (11) and adjust the deceleration rate as needed, thereby optimizing the continuity of the serve and ensuring the accuracy and consistency of each serve.

[0049] The airflow nozzle (13) is a key component that affects the airflow distribution during the serve process, and can provide additional power support for the serve process or affect the trajectory of the ball. The nozzle controller (21) is used to adjust the airflow output of the airflow nozzle (13), including the size and direction of the airflow. By adjusting the size and direction of the airflow, the effect of the airflow on the serve can be accurately controlled, thereby adjusting the flight trajectory or speed of the launched ball. By changing the size of the airflow, the nozzle controller (21) can affect the speed of the serve or increase stability; and by adjusting the direction of the airflow, the flight path or rotation direction of the ball can be changed, thereby meeting different serve requirements. In addition to the size of the airflow, the nozzle controller (21) can also adjust the direction of the airflow ejection, thereby achieving control of the flight path of the ball. This means that after the ball is launched, the flight angle and rotation of the ball can be changed according to user needs, making the serve more flexible and changeable.

[0050] In this embodiment, the brake system (20) and the brake controller (18) in the cantilever accelerator (12) realize precise deceleration control of the cantilever (11), so that the serving process is more stable and continuous; at the same time, through the design of the airflow nozzle (13) and the nozzle controller (21), the airflow can be adjusted as needed, further enhancing the control ability of the serving process.

[0051] In a feasible implementation manner, the intelligent ball serving mechanism further comprises an integrated control system (24); The integrated control system (24) is used to receive current circumferential angle information, pitch angle information, boom speed information and airflow nozzle operation information, and the integrated control system (24) is also used to transmit command signals to the circumferential angle controller (15), the pitch angle controller (16), the speed control controller (17), the brake controller (18) and the nozzle controller (21).

[0052] For example, the highly integrated and intelligent control of the integrated control system (24) allows the user to adjust the serving parameters more conveniently. Whether in terms of serving angle, speed or trajectory, the user can make precise adjustments according to needs without having to worry about the specific adjustment methods of each individual component. The integrated control system (24) simplifies the operation process, improves the user experience, and also improves the reliability and flexibility of the serving system.

[0053] This embodiment realizes unified dispatching and precise control of the components of the serving system through the integrated control system (24). The integrated control system (24) can not only receive real-time working information of each module, but also adjust the working parameters of the circumferential angle controller (15), the pitch angle controller (16), the speed control controller (17), the brake controller (18) and the nozzle controller (21) according to the information, thereby optimizing the stability and flexibility of the entire serving process and improving the performance and user experience of the intelligent serving mechanism.

[0054] In a feasible implementation, the turntable 2 and the pitch rotation axis 4 include an integrated control system 24, a horizontal angle controller 15, and a pitch angle controller 16. The turntable 2 controls the circumferential rotation angle through the horizontal angle controller 15, thereby controlling the circumferential angle of the launch port 8 of the rotating launcher; the pitch rotation axis 4 controls the pitch rotation angle through the pitch controller 16, thereby controlling the pitch angle of the launch port 8 of the rotating launcher. The horizontal angle controller 15 and the pitch angle controller 16 feed back the current angle information to the integrated control system 24, and the integrated control system 24 transmits control signals to the horizontal angle controller 15 and the pitch angle controller 16 according to the current angle information and the expected angle information, and controls the turntable 2 and the pitch rotation axis 4 to rotate respectively, thereby making the launch port 8 of the rotating launcher reach the expected angle.

[0055] The cantilever accelerator 12 includes an integrated control system 24, a speed controller 17, a brake controller 18, a drive system 19, and a brake system 20. The drive system 19 is driven by electric energy, and the drive system 19 drives the cantilever 11 to rotate; the cantilever accelerator 12 has a speed controller 17, which can adjust the rotation speed of the cantilever 11; the brake system 20 brakes the cantilever 11, and the cantilever accelerator 12 has a brake controller 18, which can adjust the deceleration rate of the cantilever 11 and adjust the rotation speed of the cantilever 11; the integrated control system 24 can transmit control signals to the speed controller 17 and the brake controller 18, and by receiving the current rotation rate information and the expected rate information of the cantilever 11, output control signals to the speed controller 17 and the brake controller 18 respectively, so as to adjust the rotation rate of the cantilever 11.

[0056] The airflow nozzle 13 includes an integrated control system 24 and a nozzle controller 21. The airflow nozzle 13 controls the size and direction of the ejected airflow through the nozzle controller 21; the integrated control system 24 can transmit a control signal to the nozzle controller 21, and transmit a new control signal to the nozzle controller 21 by receiving the jet direction and speed information of the current airflow nozzle 13 and combining the expected sphere rotation information, so as to realize the continuous adjustment of the jet direction and the paint spraying speed of the airflow nozzle 13.

[0057] The embodiment of the present invention provides an intelligent rotating serving mechanism, which can realize the serving function for small balls, and uses a turntable 2 and a pitch rotation axis 4 to adjust the circumferential rotation angle and the pitch rotation angle of a launch port 8; uses a cantilever accelerator 12 to accelerate the cantilever 11 and the hammer 10; uses a goal pipe 7 to drop a ball to be launched into a rotating launch cabin 6 and the launch port 8; uses the hammer 10 to hit the ball to realize ball launching; uses a fixed slide rail 9 to determine the direction of the ball during the launching process; and uses an airflow nozzle 13 to apply a rotational velocity vector to the launched ball.

[0058] The rotating ball-launching mechanism can launch balls of different masses at different launch speeds, different rotation directions, and different rotation speeds. When it is necessary to launch a ball of a specific mass m at a specific speed v, the rotation speed of the cantilever 11 and the motor speed in the drive system 17 can be reversely calculated based on the initial momentum required for the ball and v=ω×r; when it is necessary to launch a ball of a specific mass m at a specific rotation direction and rotation speed, the required number of working, direction, and jet speed of the airflow nozzle 13 can be reversely calculated based on the jet volume per unit time of the airflow nozzle 13. The determined speed expectation is input into the integrated control system 24, and the integrated control system 24 transmits a control signal to the speed controller 17 based on the real-time speed information, controls the cantilever to reach the expected speed, drops the ball, and completes the launch.

[0059] The rotating ball-serving mechanism of the present invention can launch balls of different sizes, different masses, different launching speeds and different rotating speed requirements by adjusting the cantilever rotation speed. It has a simple structure and strong practicality. It is a low-cost option for users or organizations that need a variety of ball-serving machines.

[0060] Second, please refer to Figure 3 The present application also proposes a control method for the intelligent serving mechanism described in any one of the first aspects, comprising: S210, the user enters user identity information through the user terminal and selects the desired serving mode; S220, the image recognition unit scans the facial information of people in the training area in real time, and determines the user's location by comparing the facial information uploaded by the current user; S230, the distance measuring unit scans and identifies the distance between the user and the intelligent serving mechanism in the training area in real time; S240, in response to the data scanned in real time by the ranging unit, controlling the rotation angles of the turntable and the pitch rotation axis to reach a predetermined angle; S250, controlling the driving system of the cantilever accelerator to start, and driving the cantilever to rotate; S260, in response to the serving mode set by the user, controlling the number of working airflow nozzles and the air outlet speed, and applying a rotation vector to the passing ball; S270, controlling the cantilever to reach a predetermined speed, and controlling the airflow nozzle to reach a predetermined direction and power; S280, throwing a target ball into the goal pipe, and striking the target ball with a hammer, so that the target ball is launched toward the target direction from the fixed slide rail.

[0061] For example, the user first inputs his / her identity information through the user terminal and selects the desired serving mode. The input of user identity information can help the system confirm the user's identity and provide data support for subsequent personalized settings. The selection of serving mode allows the user to specify different serving parameters, such as serving speed, serving angle, etc.

[0062] The image recognition unit scans the facial information of people in the training area in real time, and determines the location of the user currently using the system by comparing it with the facial information uploaded by the user. This process can realize user identity authentication and accurately determine the user's location in the training area so that the system can adjust parameters such as the serving angle according to their specific location.

[0063] The distance measuring unit scans and identifies the distance between the user and the smart serving mechanism in the training area in real time. This step is crucial for subsequent system adjustments, ensuring that the smart serving mechanism can accurately adjust the serving angle, serving speed, etc. according to the user's distance, ensuring the accuracy and adaptability of the serve.

[0064] In response to the real-time data scanned by the distance measuring unit, the integrated control system (24) controls the rotation angle of the turntable (2) and the pitch rotation axis (4) to achieve a predetermined angle. By adjusting these two components, the turntable (2) is responsible for controlling the circumferential angle, and the pitch rotation axis (4) is responsible for controlling the pitch angle. This step ensures that the serving port can be aligned with the user's position and the serving angle can be adjusted according to the distance.

[0065] After the drive system of the cantilever accelerator (12) is turned on, the cantilever (11) is driven to rotate. The rotation speed of the cantilever (11) directly affects the launch speed and launch accuracy of the ball, so this step is the key to ensuring the stability and accuracy of the ball launch process. The drive system controls the rotation speed of the cantilever through the speed controller (17).

[0066] According to the serving mode set by the user, the integrated control system (24) controls the number of working airflow nozzles (13) and the air outlet speed. The airflow nozzles apply a rotation vector to the ball by ejecting airflow, thereby affecting the trajectory and rotation effect of the serve. In this process, the nozzle controller (21) is responsible for adjusting the size and direction of the airflow to ensure that the ball flies along the expected trajectory.

[0067] The integrated control system (24) continues to monitor the status of the cantilever (11) and the airflow nozzle (13), ensuring that the cantilever (11) reaches a predetermined rotation speed, while the airflow nozzle (13) is adjusted to a predetermined direction and power according to demand. This step ensures that the cantilever moves accurately when serving, and the airflow nozzle can accurately affect the trajectory and rotation effect of the ball.

[0068] When a target ball is thrown into the goal tube (7), the hammer (10) strikes the target ball by cooperating with the cantilever (11). The hammer (10) is located at the rear end of the cantilever (11) and launches the ball out of the launch port (8) at a predetermined speed and direction. At this time, the ball is launched toward the target direction through the fixed slide rail (9).

[0069] In summary, this embodiment ensures that the intelligent serving mechanism can automatically adjust the serving angle, speed, rotation and other parameters according to the user's identity, position and needs through a series of precise control steps. Each step is dispatched and controlled by the comprehensive control system, which monitors and adjusts the system status in real time, thereby achieving accurate, intelligent and personalized serving effects.

[0070] In a feasible implementation, it also includes: The image recognition unit monitors the emitted target sphere in real time; In response to monitoring data of whether the target ball falls back into a specified area by the image recognition unit, determining whether the user successfully catches the ball; Counting the success rate of receiving the ball of different types of serves of the user, wherein the different types of serves are serves with different rotation speeds and / or launch speeds; In response to the recorded user ball catching information, the ball catching success rates at different rotation speeds and different serving speeds are uploaded to the corresponding user information of the backend server; Generate a targeted training plan based on the user information.

[0071] Exemplarily, the image recognition unit is not only used to determine the user's position, but also to monitor the trajectory of the launched target ball in real time. Through efficient image recognition technology, the system can track the movement path of the ball and obtain real-time information on whether the ball has fallen back to the predetermined area. This function ensures that the system can continuously monitor the movement state of the ball and provide a basis for subsequent judgment of whether the ball is successfully caught. The system determines whether the target ball falls back into the specified area by analyzing the data monitored by the image recognition unit. The specified area is usually a specific area within the training ground, such as a designated catching area. If the target ball falls back into the area and no other abnormalities occur (such as the ball flying out of bounds), the system determines that the user has successfully caught the ball.

[0072] The statistics of the catch success rate are based on the user's performance in different serve modes. Different types of serves refer to different serve methods produced by adjusting the spin speed and / or launch speed of the serve. The system records the type of each serve (e.g. high-spin fast ball, low-spin slow ball, etc.) and analyzes the user's catch success rate. The catch success rate is calculated by comparing the relationship between the ball received by the user and the ball launched. The statistical indicators include the number of successful catches and the number of failed catches.

[0073] All ball catching information (including the ball catching success rate and the specific performance of the user) will be recorded in real time by the integrated control system (24) and uploaded to the backend server. This information is associated with the user's personal information (such as name, training history, etc.) to form a user information file. The backend server stores all the user's training data and can process this data for subsequent analysis.

[0074] Based on the user information stored in the background, the system will use the recorded data such as the success rate of receiving the ball, the performance of different types of serves, etc. to generate personalized targeted training plans. These training plans are designed to improve the training effect according to the user's actual performance and needs. For example, if the user performs poorly in receiving high-spin balls, the system may recommend more high-spin ball exercises, or adjust the spin speed and launch angle of the serve to help the user better adapt to different serve types.

[0075] This embodiment can not only accurately monitor and record the user's training performance through the cooperation of the image recognition unit, statistical analysis and the backend server, but also generate a personalized training plan based on these data, thereby effectively improving the user's training effect. By accurately counting the user's ball receiving success rate and serve type, the system can help the user focus on weaknesses and optimize training progress.

[0076] In a feasible implementation, it also includes: When the image recognition unit fails to detect the user's facial information in the specified training area within a preset time, the intelligent serving mechanism is controlled to stop operating.

[0077] Exemplarily, the image recognition unit is responsible for scanning the user's facial information in the training area in real time. The system confirms whether the user is in the training area and actively participates in the training by identifying and comparing the user's facial features. If the image recognition unit fails to successfully detect the user's facial information within a preset time (e.g., a few seconds to a few minutes), it indicates that the user may no longer be in the training area, or the user may have left the area, causing the training process to be unable to continue.

[0078] In the above case, when the image recognition unit fails to detect the user's facial information, the system will automatically execute a safety measure, that is, control the intelligent ball serving mechanism to stop operating. The purpose of this operation is to ensure that the intelligent ball serving mechanism will not continue to serve when the user is not in the training area, to avoid meaningless ball launch or other possible safety hazards. At this time, the system will send instructions to the integrated control system (24), which will control the stop of various related components, including the turntable (2), the pitch rotation axis (4) and all other ball serving mechanisms.

[0079] The preset time is a time threshold set by the system, which is usually adjusted according to actual usage. For example, the system may be set to execute a stop command when the user's facial information is not detected within 10 seconds, 30 seconds or 1 minute. This time length is to ensure that the system can continue to monitor the user's behavior even if the user leaves the training area for a short time or is temporarily absent.

[0080] The method proposed in this embodiment adds a safety measure to ensure that the intelligent serving mechanism will only operate when the user is actively in the training area. When the user leaves the training area for some reason or the system cannot recognize the user, the intelligent recognition function of the image recognition unit can play an automatic judgment and response role, and stop the serving mechanism in time through the comprehensive control system to avoid unnecessary actions and potential safety problems.

[0081] In a feasible implementation, the background server is used to store information of the intelligent serving mechanism, and stores the user's facial information, the ball receiving success rate and the number of training times in different serving modes in a database corresponding to the user's unique ID.

[0082] Exemplarily, the backend server is the central control and data storage unit of the entire system. It is not only used to process and analyze data, but also responsible for the interaction and management of data between various components in the system. Through the connection with the intelligent serving mechanism, the backend server can receive various information about the user's training process, and store, analyze and subsequently process this information.

[0083] Facial information refers to the user's facial feature data collected by the image recognition unit. The system uses facial recognition technology to authenticate the user and ensure that the correct user is using the ball machine. In this embodiment, the facial information will be stored in the background server and bound to the user's unique ID. In this way, in the user's subsequent training, the system can quickly identify and match the user's training records and preference settings.

[0084] During the user's training process, the system will record the user's catch success rate in different modes based on the user's serving mode and receiving performance. For example, at different rotation speeds and serving speeds, the user's success or failure in catching the ball will be recorded as a catch success rate. At the same time, the system will also record the user's training times, that is, the total number of times the user has practiced serving. This information will also be associated with the user's unique ID and stored in the database.

[0085] Each user has a unique ID in the system. Through this unique ID, the backend server can accurately match the user's facial information, ball catching success rate, training times and other data with the user, thereby realizing personalized data management. Every time the user trains, the backend server will update the relevant information based on this ID to ensure that the user's training data is accurate and timely.

[0086] All collected information, including facial information, ball catching success rate, number of training sessions, etc., will be stored in a database on the backend server. This data will be updated after each training session and can be called up and analyzed at any time according to the user's needs. The database storage structure ensures the security, accuracy and accessibility of the data, allowing the system to provide users with customized training feedback and plans based on this data.

[0087] like Figure 4 and Figure 5 As shown, the user terminal 23 may be a mobile phone app. The user can enter identity information through the mobile phone app, including obtaining a unique ID and uploading a facial photo of the user as facial information for identification.

[0088] In one embodiment, the user terminal 23 is a mobile phone app. The user can select a serving mode through the mobile phone app, and the serving mode is divided according to the launch speed, rotation direction, and rotation speed of the ball.

[0089] In one embodiment, the image recognition unit 22 may use a camera group consisting of multiple cameras. The camera group may be selected according to the size of the training area corresponding to the selected ball, and the camera group is used to collect facial information of people in the training area in real time and monitor the position of the launched ball in real time.

[0090] In one embodiment, the distance measuring unit 14 may be a laser radar. The laser radar is used to scan the specified training area in real time and measure the distance d between the serving mechanism and the user in real time, where the distance d is the straight-line distance between the user and the launch port of the intelligent rotating serving mechanism at the current moment.

[0091] In one embodiment, the background server 25 is used to store information of the intelligent rotating serving mechanism, and stores the user's facial information, the success rate of receiving the ball in different serving modes, the number of training times and other information in a database corresponding to the user's unique ID.

[0092] In one embodiment, the certain time can be set by oneself, and can be generally set to 60 seconds. If the image recognition unit 22 fails to detect the user's facial information in the specified training area within 60 seconds, the intelligent rotating serving mechanism stops operating.

[0093] In one embodiment, the image recognition unit 22, the user terminal 23, the backend server 25 and the integrated control system 24 are in communication connection. The user can register personal information and upload facial information using the user terminal 23. The integrated control system 24 uploads the information collected by the user terminal 23 to the backend server 25, and selects the serving mode (ball launching speed, rotation direction, and rotation speed) in the user terminal 22; the image recognition unit 22 collects facial information of people in the training area in real time, and compares the facial information of the user stored in the integrated control system 24 with the backend server 25 to confirm the position of the user in the training area. When the facial information of the user does not appear in the specified training area within a certain period of time, the integrated control system 24 sends a termination signal to stop the operation of the intelligent serving mechanism; the image recognition unit 22 keeps real-time monitoring of each launched ball for 10 seconds, and transmits the status of each ball to the integrated control system 24. The integrated control system 24 determines whether the ball is successfully received by determining whether the ball falls into a designated area within the training area, and uploads the ball receiving success rate information to the backend server 25; the backend server 25 is used to store information of the intelligent rotating serve mechanism, including the user personal information and facial information uploaded by the user terminal 23, the status information of each serve (the launching speed, rotation direction, and rotation speed of the ball) uploaded by the integrated control system 24, and the ball receiving success rate information recorded and uploaded by the image recognition unit 22; the backend server 22 stores the status information of each serve and the corresponding ball receiving success rate in the corresponding user information, so that the user can view the personal ball receiving success rate of different serve categories in the user terminal 23, and then select a targeted serve mode.

[0094] In one embodiment, the turntable 2, the pitch rotation axis 4, the distance measuring unit 14, the horizontal angle controller 15, the pitch angle controller 16, the image recognition unit 22, the backend server 25 are connected to the integrated control system 24. The image recognition unit 22 collects the facial information of the personnel in the training area in real time, compares the facial information of the user stored in the integrated control system 24 and the backend server 25, confirms the position of the user in the training area, and uploads the real-time position information of the user to the integrated control system 24; the distance measuring unit 14 scans the specified training area in real time, and measures the distance d between the serving mechanism and the user in real time, the distance d being the straight-line distance between the user and the launch port of the intelligent rotating serving mechanism at the current moment, and uploads the real-time distance information to the integrated control system 24; in response to the real-time position information and distance information of the user, the integrated control system 24 transmits control signals to the horizontal angle controller 15 and the pitch angle controller 16, controls the turntable 2 to rotate in a circumferential direction, and the pitch rotation axis 4 to rotate in a pitch direction, and then adjusts the direction of the launch port 8, so that the ball launch direction follows the user's movement in real time.

Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
