Technical Field

[0001] This application relates to the field of tennis training equipment technology, and more particularly to an interactive tennis practice system. Background Technology

[0002] With the increasing popularity of tennis, more and more sports enthusiasts want to try the sport. In existing tennis training and entertainment systems, using tennis machines for serving has become an important means to improve training efficiency and increase entertainment value. However, in practical applications, it has revealed the problem of an unrealistic experience.

[0003] Specifically, current interactive tennis practice systems are designed with one tennis machine per player, meaning each player uses only one machine for training. However, the machine does not need to move during the serve; it works by accurately hitting the tennis ball to the designated landing point through a preset program and mechanical structure. This results in an unrealistic experience when using the machine for tennis practice. Utility Model Content

[0040] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0041] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component. The terms "top," "bottom," "upper," "lower," "left," "right," "front," "back," and similar expressions used in this article are for illustrative purposes only.

[0042] Embodiments of this application provide an interactive tennis practice system, comprising:

[0043] A ball-serving machine is located at one end of the tennis practice court. Multiple ball-serving machines are symmetrically arranged on both sides of the center line e in the length direction of the tennis practice court. When the total number of ball-serving machines is odd, one ball-serving machine is placed on the center line e.

[0044] A control component, located within the tennis practice court and communicatively connected to the ball-serving machines, controls the ball-serving machine closest to the landing point of the tennis ball to serve. The interactive tennis practice system described above utilizes multiple ball-serving machines symmetrically arranged on both sides of the tennis practice court. This design allows for the configuration of multiple ball-serving machines within a limited space, providing the system with more serving points and enabling control of the ball-serving machine closest to the landing point for returning the ball, thus simulating a more realistic tennis experience.

[0045] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0046] Please see Figures 1-8 This application provides an interactive tennis practice system 100, including a tennis practice court 1, ball machines 2, and a control component 3. The ball machines 2 are located within the tennis practice court, and multiple ball machines 2 are symmetrically arranged on both sides of the center line e along the length direction of the tennis practice court 1. The control component 3 is located within the tennis practice court 1 and is communicatively connected to the ball machines 2. The control component 3 controls the ball machine 2 closest to the landing point of the tennis ball to serve the ball.

[0047] Specifically, the ball machines 2 are symmetrically arranged on both sides of the center line e. This design allows multiple ball machines 2 to serve from different positions, increasing the diversity and flexibility of players' post-hit return training. By configuring multiple ball machines 2, players can practice serving and receiving from different positions. This layout allows players to experience various serving angles and landing points, simulating the situation in a real match. Regardless of which ball machine 2 the ball lands on, there is a corresponding ball machine 2 to return the ball. This design allows players to adapt to various serving strategies, improving their adaptability and reaction speed, making training more realistic. When the total number of ball machines 2 is odd, one ball machine 2 is placed on the center line e, and the center line e bisects the ball machine 2. When the total number of ball machines 2 is even, multiple ball machines 2 are symmetrically distributed on both sides of the center line e. This design makes the number of ball machines on both sides of the center line e more even, thus maintaining a more balanced serving ability on both sides of the tennis practice court. After receiving the landing point data signal, the ball serving machine returns the ball according to the preset program. The preset ball serving program is a common function of existing ball serving machines.

[0048] Furthermore, the layout of multiple ball-serving machines 2 within a tennis court ensures that the ball-serving machines 2 can accurately serve according to the player's needs and training goals, improving the effectiveness of practice. The control component 3 is responsible for calculating the landing point of the tennis ball and controlling the ball-serving machine 2 closest to the landing point to serve. This intelligent control mechanism not only improves training accuracy but also simulates real match scenarios, enhancing the player's reaction time and ability to correctly return to position after hitting the ball. The relationship between the ball-serving machine 2 and the control component 3 is the core of the interactive tennis practice system 100, involving data transmission, command control, and operational coordination. The ball-serving machine 2 and the control component 3 are connected via a communication interface (such as a wireless network or Bluetooth) to achieve bidirectional data transmission. The control component 3 can receive status information from the ball-serving machine 2 and simultaneously send control commands to it. The ball-serving machine 2 can feed back the serve's status, landing point, and other relevant data to the control component 3, ensuring the system can update training data in real time. The control component 3 is responsible for calculating the landing point of the tennis ball and, based on the landing point information, issuing commands to control the ball-serving machine 2 closest to the landing point to serve. Control component 3 collects tennis ball trajectory data via ball trajectory capture device 31. This data is typically acquired by high-precision sensors (such as cameras, infrared, or laser sensors) and can monitor the ball's speed, angle, and flight path in real time. Control component 3 analyzes the captured trajectory data to extract key flight parameters, such as initial velocity, serving angle, and spin. These parameters are crucial for predicting the landing point. Utilizing principles of physics, control component 3 uses equations of motion to simulate the tennis ball's flight trajectory, including factors such as gravity and air resistance, to accurately calculate the ball's landing point. Based on known flight parameters, control component 3 uses mathematical models (such as parabolic models) to calculate the tennis ball's landing position. This process involves complex mathematical calculations to ensure the accuracy of the landing point prediction. As the ball flies, control component 3 continuously updates the landing point prediction to adapt to changes in parameters during flight, ensuring real-time feedback. The calculation process of control component 3 can be performed using devices such as computers. Control component 3 has a built-in algorithm that calculates the tennis ball's landing point based on the captured ball trajectory data, thereby determining which serving machine 2 should serve. This calculation process needs to be processed in real time to ensure the smoothness of training. The ball-serving machine 2 and the control component 3, as the two core components of the system, work together to achieve comprehensive training functions. The decision-making ability of the control component 3 and the execution ability of the ball-serving machine 2 complement each other, jointly enhancing the training experience.

[0049] In one specific example, the control component 3 includes:

[0050] The ball trajectory capture device 31 is installed in the tennis practice court 1. The ball trajectory capture device 31 calculates the landing point of the tennis ball and converts the landing point information of the tennis ball into landing point data for output.

[0051] The sensing device 32 is connected to the ball trajectory capturing device 31. The sensing device 32 sends control signals to multiple ball-serving machines 2 based on the landing point data. The sensing device 32 controls the ball-serving machine 2 closest to the landing point of the tennis ball to serve the ball through the control signals.

[0052] Specifically, the ball trajectory capture device 31 is primarily responsible for real-time monitoring and analysis of the tennis ball's flight trajectory. These components typically include high-precision cameras, infrared sensors, or other sensors capable of accurately acquiring the ball's motion parameters. Based on the captured data, the ball trajectory capture device 31 uses algorithms to calculate the tennis ball's landing point. It considers factors such as speed, angle, and spin to simulate the tennis ball's path. After the calculation is complete, the ball trajectory capture device 31 converts the landing point information into landing point data. This data includes the exact landing location of the tennis ball, as well as possible variations in the landing point. The calculation portion of the ball trajectory capture device 31 can be performed on a computer by a corresponding computer program or by a dedicated computing device.

[0053] Furthermore, the sensor 32 is data-connected to the ball trajectory capture device 31, receiving landing point data in real time. It acts as a bridge between the two, ensuring smooth information flow. Based on the landing point data, the sensor 32 sends control signals to multiple ball machines 2. These signals instruct the operation of each ball machine 2, including when to serve and which ball machine 2 to select. By analyzing the landing point data, the sensor 32 can determine the ball machine 2 closest to the landing point of the tennis ball and instruct it to serve. This mechanism ensures the real-time nature and effectiveness of the serve, making training more realistic. The sensor 32 has a direct data connection with the ball trajectory capture device 31. It receives landing point data output by the ball trajectory capture device 31 in real time, including the landing position of the tennis ball and related flight parameters. The sensor 32 first analyzes the received landing point data to determine the exact landing point of the tennis ball. This analysis considers various factors, such as the distance between the ball machine 2 and the landing point, and the availability of the ball machine 2. The sensor device 32 calculates the distance from each ball-serving machine 2 to the landing point, determining which ball-serving machine 2 is closest to the landing point. This process may involve simple geometric calculations or use more complex algorithms to ensure accuracy. Once the ball-serving machine 2 closest to the landing point is determined, the sensor device 32 generates corresponding control signals. These signals typically include instructions such as "serve" or "adjust serve parameters," ensuring that the ball-serving machine 2 can accurately execute the task. The control signals may be formatted with a specific protocol so that the ball-serving machine 2 can recognize and correctly execute the instructions. The control signals are sent to the selected ball-serving machine 2 via wireless transmission (such as Bluetooth or Wi-Fi) or a wired connection. This rapid signal transmission ensures that the ball-serving machine 2 can respond promptly. Upon receiving the control signal, the ball-serving machine 2 immediately performs the corresponding operation, such as serving, adjusting the serve angle or speed, etc., to ensure that its serve matches the landing point. The execution results of the ball-serving machine 2 (such as the flight trajectory of the served ball) may be fed back to the sensor device 32 for subsequent training analysis and improvement.

[0054] In one specific example, the ball path capturing device 31 includes:

[0055] The ball trajectory detection module 311 is used to detect the flight trajectory of a tennis ball.

[0056] The ball path calculation module 312 is connected to the ball path detection module 311. The ball path calculation module 312 calculates the landing point of the tennis ball based on its flight trajectory.

[0057] The ball path signal transmission module 313 is data-connected to the ball path calculation module 312. The ball path signal transmission module 313 converts the landing point information of the tennis ball into landing point data and outputs it to the outside world.

[0058] Specifically, the ball trajectory detection module 311 is responsible for monitoring the flight trajectory of the tennis ball in real time. It is typically composed of high-precision sensors (such as cameras, infrared lasers, or radar sensors) capable of capturing data such as the ball's speed, direction, and altitude. This module continuously acquires the ball's motion data, forming a continuous record of the flight trajectory to ensure that the ball's motion state can be reflected in real time. The ball trajectory detection module 311 needs to have high precision and fast response capabilities to capture the high-speed flying tennis ball and ensure the accuracy of subsequent calculations. The ball trajectory calculation module 312 is data-connected to the ball trajectory detection module 311 and receives its output flight trajectory data. Based on the acquired flight trajectory data, the ball trajectory calculation module 312 uses physical models and mathematical formulas (such as the parabola formula) to calculate the landing point of the tennis ball. It considers gravity, air resistance, and other factors that may affect the flight trajectory. The ball trajectory calculation module 312 can update the landing point calculation in real time based on the constantly changing flight trajectory data to ensure accurate landing point information. The ball trajectory signal transmission module 313 is data-connected to the ball trajectory calculation module 312 and receives landing point information. The calculated tennis ball landing point information is converted into landing point data and output to the outside world in a specific format. This data can be used for subsequent training analysis or control command generation. The landing point data can be transmitted wirelessly (such as Wi-Fi, Bluetooth) or via wired means to ensure timely transmission of information to other system components (such as sensor device 32). The ball trajectory calculation module 312 can be a computer or other device; processing the data using a computer is a common method.

[0059] In one specific example, the sensing device 32 includes:

[0060] A receiving and conversion module 321 is data-connected to the ball path signal transmitting module 313, and the receiving and conversion module 321 receives the landing point data output by the ball path signal transmitting module 313;

[0061] The landing point determination module 322 is used to determine whether the landing point of the tennis ball is within the court boundary based on the landing point data. If the landing point of the tennis ball is within the court boundary, the landing point determination module 322 outputs a transmission signal.

[0062] The control module 323 is connected to the launch judgment module 322. The launch judgment module generates a control signal based on the launch signal. The control signal controls the ball-serving machine 2, which is closest to the landing point of the tennis ball, to serve.

[0063] Specifically, this module is data-connected to the ball path signal transmission module 313 and is primarily responsible for receiving landing point data output from the ball path signal transmission module 313. The received landing point data may require format conversion for processing by subsequent modules. This module ensures that data can be transmitted to the landing point judgment module 322 in the correct format and structure. This module is designed to have a fast response capability to acquire landing point data in real time, ensuring the smoothness and timeliness of the system. The main task of this module is to determine whether the tennis ball's landing point is within the court boundaries based on the received landing point data. This determination typically involves a simple boundary condition check to determine if the landing point is within the preset court area. If the landing point is within the court boundaries, the landing point judgment module 322 will output a transmission signal, instructing the ball machine 2 to prepare to serve. Otherwise, no signal will be output to avoid unnecessary serving operations. A data connection exists between the transmission judgment module and the landing point judgment module 322 to ensure smooth information flow. The control module 323 generates control signals based on the transmission signals output by the landing point judgment module 322. These control signals instruct the ball machine 2, which is closest to the tennis ball's landing point, to perform the serving operation. The control signals can include not only the timing of the serve, but also adjustments to the angle and speed of the serve to adapt to different training needs. The intelligent decision-making capability of the control module 323 enhances the system's flexibility and adaptability.

[0064] In one specific example, the interactive tennis practice system 100 further includes:

[0065] Scoring component 4 is connected to the ball trajectory capture device 31. Scoring component 4 calculates the tennis score based on the landing point data and generates score data based on the calculation result.

[0066] Specifically, the scoring component 4 is data-connected to the ball trajectory capture device 31, enabling it to receive real-time landing point data from the device. This direct data connection ensures that the scoring component 4 can promptly acquire information about the ball's flight and landing point. The scoring component 4 calculates the score based on the received landing point data. The scoring may be based on multiple factors; different scores may be awarded for a tennis ball landing in a specific area (e.g., in bounds, out of bounds, or a specific scoring zone). The difficulty of the serve and the player's reaction speed may also affect the score. The scoring component 4's ability to calculate scores in real-time means that the score can be quickly updated after each shot, enhancing the interactivity of training. After calculating the score, the scoring component 4 generates score data based on the calculation results. This data typically includes the current score, total score, and possibly other statistical information (e.g., average score, historical high score). The score data may be output in a specific format for subsequent display or storage. This data can be used for training records, match statistics, or comparison with other players. Through the scoring system, players can receive immediate feedback during training, motivating them to improve their skills and performance and increasing the enjoyment of training. The collection and recording of scoring data provides a foundation for subsequent analysis, helping players and coaches evaluate training effectiveness and adjust training strategies. The scoring component can be implemented using devices with scoring capabilities, such as computers, while data connectivity can be achieved wirelessly via communication methods such as Bluetooth and Wi-Fi.

[0067] In one specific example, the scoring component 4 includes:

[0068] The difficulty judgment module 41 is connected to the ball trajectory capture device 31. The difficulty judgment module 41 determines the scoring difficulty data of the tennis ball based on the landing point data.

[0069] The score generation module 42 is data-connected to the difficulty judgment module 41, and generates score data based on the score difficulty data.

[0070] Specifically, the main task of the difficulty judgment module 41 is to analyze the landing point data received from the ball trajectory capture device 31 and determine the difficulty data for scoring the tennis ball. This process involves multiple factors, including landing point location, flight trajectory, player reaction time, and data output. Different areas of the court (such as corners, sidelines, and the center of a tennis practice court) correspond to different scoring difficulties. For example, a landing point near the boundary might be considered a more challenging shot. The flight trajectory and speed of the tennis ball also affect the scoring difficulty. If the ball speed is high and the landing point is far away, the difficulty of receiving the ball naturally increases. Player reaction time combines the player's reaction speed and hitting technique; the difficulty judgment module 41 can assess the actual challenge the player faces with each serve. Data output involves the difficulty judgment module 41 converting the analysis results into scoring difficulty data and outputting it to the next module. The score generation module 42 is responsible for calculating the actual score based on the scoring difficulty data generated by the difficulty judgment module 41. According to preset rules (e.g., score values ​​corresponding to different difficulties), the score generation module 42 converts the difficulty data into specific score data. This can be a simple addition or a more complex weighted calculation. The module can update scores in real time, ensuring that the score data quickly reflects the player's performance after each shot. The score generation module 42 generates score data that may include the current score, total score, historical scores, etc., and outputs it to the user interface or display 5 for players and coaches to view. The score generation module 42 is a key component of the interactive tennis practice system 100. Its main function is to generate specific score data based on the scoring difficulty data provided by the difficulty judgment module 41. For example, a rules-based scoring system can set a fixed set of scoring rules, such as dividing scores according to difficulty levels. For example, easy difficulty gets 1 point, medium difficulty gets 2 points, and difficult difficulty gets 3 points. This method is simple to understand and easy to implement and adjust. Extra points can be awarded based on the number of consecutive successful shots or the increase in challenge difficulty. For example, 5 consecutive successful shots earn an extra point. The specific calculation function of the score generation module 42 can be implemented by the corresponding computer program. Generally, the closer the tennis ball lands to the sideline, the greater the difficulty and the higher the score.

[0071] In one specific example, the interactive tennis practice system 100 further includes:

[0072] Display 5 is connected to the scoring component 4 via data connection, and the display 5 converts the scoring data into image information for display.

[0073] Specifically, Display 5 can display a player's scoring status in real time during practice. This includes the current score, historical high score, number of shots, etc. Through visualization, players can intuitively understand their performance, enhancing their engagement and competitive spirit. Display 5 can provide feedback on player performance, such as shot accuracy, speed, and landing point statistics. This feedback helps players quickly identify their strengths and weaknesses, facilitating targeted improvements in training. Display 5 can display different training modes or challenge tasks, such as "10 consecutive shots" or "score within a specific area." This design increases the fun of training and encourages players to try different goals. Display 5 can display player achievements and leaderboards, including personal bests and comparisons with other players. Through a visualized achievement system, players can gain more motivation and enhance competitiveness. Display 5 connects to the scoring component 4 via data connections (such as USB, Wi-Fi, Bluetooth, etc.) to receive scoring data and other relevant information in real time, including scoring information, shot statistics, difficulty level, etc., ensuring that Display 5 can display the latest information. The display 5 may have an integrated data processing module to process the received data and convert it into a format suitable for display. For example, it could convert score data into charts, numbers, or dynamic images to present it to the user in a more intuitive way.

[0074] In one specific example, the display 5 is a screen.

[0075] Specifically, displays can intuitively present information, including scores, statistics, and feedback, in the form of graphics, text, and animation. This visualization allows users to quickly understand their performance without complex explanations. Unlike traditional paper or verbal notifications, displays significantly improve readability and reduce the possibility of misunderstandings. Displays can receive real-time data updates from the system, promptly displaying players' latest scores and performances. This instant feedback motivates players to maintain a high level of focus during training. Players can adjust their strategies based on real-time information, such as changing their shot type or target, improving training effectiveness. By using vivid graphics and animations, displays can attract players' attention, increase their engagement, and enhance the enjoyment of training. In team training or competitions, displays can show the scores of all participants, enhancing the competitive atmosphere and encouraging mutual motivation among players. Displays can flexibly display various types of information, including score statistics, training modes, challenge tasks, achievement unlocks, etc., to meet different training needs. Displays typically have touch or remote control functions, allowing users to quickly adjust the displayed content or switch modes. Modern displays typically feature multiple data interfaces (such as HDMI, USB, Wi-Fi, etc.) to seamlessly connect with other devices such as the scoring component 4 and control module 323, ensuring stable data transmission. Displays can also be combined with other technologies (such as augmented reality or virtual reality) to provide users with a richer training experience.

[0076] In one specific instance, in the first case, the number of ball-launching machines 2 is two.

[0077] Specifically, using two ball machines (2) instead of multiple ball machines (2) can significantly reduce initial equipment purchase costs. Furthermore, two ball machines (2) can meet the needs of multiple ball machines (2) returning balls to players from different landing points. Ball machines (2) are typically more expensive, so reducing their number directly alleviates the financial burden. Fewer ball machines (2) also mean lower maintenance and upkeep costs. Ball machines (2) require regular inspection and repair; reducing their number reduces maintenance workload and expenses. Moreover, if indoor tennis court space is limited, a setup of two ball machines (2) better adapts to the spatial layout, avoiding wasted space. This design helps improve court utilization efficiency, especially in small indoor courts. Optimizing the number of ball machines (2) can save on court rental costs. In situations with limited space, reducing the space occupied by equipment helps lower overall court usage costs.

[0078] In one specific instance, in the second case, the number of ball-launching machines 2 is three.

[0079] Specifically, setting the number of ball machines 2 to three means that three ball machines 2 can be used simultaneously in the system. This configuration makes training more flexible and can be adjusted according to the player's needs. The three ball machines 2 can cover different landing areas, allowing players to receive balls from multiple ball machines 2 during training, helping them improve their ability to cope with various situations. With three ball machines 2, players can receive balls from different positions, simulating various hitting angles and landing points that may be encountered in a match, improving their reaction time and hitting skills. Different ball machines 2 can be set to serve different types of balls (such as fast balls, spin balls, backspin balls, etc.), helping players practice multiple skills in one training session. Because there are multiple ball machines 2, after receiving a ball, players can immediately return to a theoretically appropriate position to prepare for the next ball, as part of running training, reducing waiting time during training and improving training efficiency. Each ball machine 2 has a certain serving range when serving, which is usually limited by the design and position of the ball machine 2. Setting the number of service machines 2 to three ensures that the serving area of ​​each machine 2 covers key parts of the entire training court. By using three service machines 2, the workload of each machine 2 can be rationally distributed, ensuring that each machine 2 operates at its optimal performance and avoiding performance degradation or malfunction due to overload. Setting the number of service machines 2 to three ensures effective utilization of each area within the fixed space of an indoor tennis court. This configuration reduces unnecessary open areas, making training more focused and effective. The design of three service machines 2 is a reasonable distribution method considering the size of the machines, allowing players to quickly move to the next receiving position after receiving the ball, improving the smoothness and efficiency of training.

[0080] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
