Description

Technical Field

[0001] This utility model relates to a sports training equipment, particularly a golf practice device, specifically a portable multi-parameter intelligent training system for putting greens. Background Technology

[0002] Swing and putting are two of the most important fundamental skills in golf, directly affecting the number and quality of shots into the hole. Swing practice equipment is now quite common and inexpensive, but putting practice equipment is relatively scarce. To improve their putting technique, golfers typically need to practice on golf courses or similar training facilities, which is very expensive and time-consuming. While some practice machines are available on golf courses or training facilities, they are very expensive and difficult to use without going to the golf course or training facility. For example, a system that uses high-speed cameras for assisted practice requires multiple complex high-speed cameras to record and analyze the putter's putting parameters. This results in two problems: delayed guidance and inconvenient relocation. Once the equipment is set up, it is difficult to move, and moving it from indoors to the green or vice versa requires many people and a lot of time for repeated adjustments, making it very inconvenient to use.

[0003] To the applicant's knowledge, there are currently three related products available for public use:

[0004] 1. Trackman (https: / / trackman.com / golf / trackman-4 / putttngl) uses high-precision optical-enhanced radar tracking (DERT) and camera sensors. It collects data on the flight and roll of a golf ball by utilizing the reflections from the dimples on the surface of the ball. The data is then processed to improve the technology. It can be used both indoors and outdoors.

[0005] 2. Quinuc (https: / / www.quinticballroll.com) uses a high-speed camera system to track the rolling trajectory of the golf ball (which has special markings on it) during a putter stroke at 360-1080 frames per second. This data is then analyzed using analytics software to improve putting techniques. It can be used both indoors and outdoors.

[0006] 3. SAM PuttLab (https: / / www.scienceandmotion.com.translate.goog / puttLab) uses ultrasonic technology. An ultrasonic transmitter is placed on the putter shaft, emitting three ultrasonic waves to three receivers positioned in an inverted triangle opposite each other. The receivers receive signals indicating changes in the stick's rotation and movement, allowing for real-time 3D measurement and comprehensive analysis to evaluate player technique and make improvements. It is for indoor use only.

[0007] These three companies are all leading brands in the golf industry. However, they are all expensive, technologically complex, and require specific operating conditions. Trackman excels in swing technique, capturing data on the golf ball's flight to inform improvements. For putting, since the ball rolls on the ground, data is supplemented only through video recording. Quintic requires marking the golf ball, placing it in a specific location, and installing high-speed cameras above and to the side before training can begin.

[0008] SMA is limited to indoor training. The receiver is fixed in a specific position, and the pole must be directly facing the receiver to begin training.

[0009] In summary, there is a desire to develop an inexpensive golf training system suitable for home practice without the need for expensive facilities. This system should measure putting deflections, including putting speed, club angle, and accuracy of the golf ball strike, and report the results to the golfer in real time during putting practice to guide and improve his / her golf 15 technique. Utility Model Content

[0010] The purpose of this invention is to address the problem that the lack of affordable golf putting practice equipment hinders the improvement of the general public's skill level. The invention proposes a simple, low-cost, portable, and effective multi-parameter intelligent golf putting training system.

[0011] One of the technical solutions of this utility model is:

[0012] A portable intelligent training system for putting on the green, characterized in that it includes:

[0013] A bracket 1 is used to mount the electromagnetic induction sensor 2 and the electronic control components, and to make the entire training system easy to carry and move;

[0014] A sensor 2 is installed on two legs of the bracket. At least two sensor 2s are installed on each leg. The two corresponding sensor 2s on the two legs form a set of electromagnetic induction sensing elements. The distance between each set of sensing elements is sufficient to ensure that the golf club head passes through smoothly and that the sensing elements on both legs can sense the change in electromagnetic signal. The speed and deflection angle of the putter head are calculated by calculating the time difference and intensity of the sensing signals received by the two sets of sensing elements.

[0015] An electronic control element 3 is used to receive the signal strength and time difference obtained by the sensor 2 and transmit them to the computer system 4 in real time via wired or wireless means. After calculation and analysis, the speed and angle of the push rod are displayed in real time and compared with the preset standard value so that the coach or trainee can make improvements.

[0016] A power supply 5, which is an external power source or a battery, is used to power the entire training system.

[0017] The distance between the two sensing elements on each of the legs is adjustable.

[0018] The distance between each set of sensing elements on the two legs is adjustable.

[0019] A first gyroscope 7 is installed at any position of the bracket 1 to detect its position slope and send it to the computer system as a basis for correction calculation so as to better adapt to putting practice in the green area.

[0020] The computer system is one of the following: mobile phone, iPad, portable computer, or display with computing capabilities.

[0021] The matching golf club shaft 6 is equipped with a second gyroscope 8 to monitor the clubhead 3D attitude, clubface angle and acceleration in real time.

[0022] The bracket 1 has a U-shaped or π-shaped structure, and its openings are used to place golf balls.

[0023] The second technical solution of this utility model is:

[0024] A portable multi-parameter intelligent training system for putting greens on a flat plate includes a mounting plate (9). The mounting plate 9 is characterized by having two sets of four electromagnetic induction sensing elements 10 installed on it. The electromagnetic induction sensing elements 10 are used in pairs to sense the change in electromagnetic signal when the golf clubhead passes by. The speed and deflection angle of the putting head are calculated by calculating the time difference and intensity of the sensing signals received by the two sets of sensing elements. The mounting plate 9 is also equipped with a main control board, a gyroscope, a battery and other supporting electrical components 11, as well as a display.

[0025] The components are arranged in an H-shape. Four electromagnetic induction sensing elements 10 are arranged at both ends of the two vertical sides of the H-shaped structure, and the main control board, gyroscope and battery are arranged on the horizontal bar of the H-shaped structure.

[0026] The beneficial effects of this utility model are:

[0027] This utility model relates to a portable intelligent golf putting practice system, which is a practice system focused on training the sense of direction and distance in putting.

[0028] This portable intelligent golf putting practice system can instantly measure and display the putter's impact speed, the angle of deviation between the clubface normal and the target line before and after impact, during putting training. This data is immediately transmitted via Bluetooth to the user's mobile phone or tablet, and simultaneously communicated verbally. Accurate data collection, recording, and processing provide coaches and practitioners with a reliable basis for improving their techniques.

[0029] This utility model's portable intelligent golf putting practice system can be placed directly on the green for on-site practice, adapting to the surface conditions of greens on different golf courses and the different technical requirements for putting.

[0030] This portable intelligent golf putting practice system can be used both indoors and outdoors. A key feature is its ability to perform both with and without a ball. Based on outdoor practice data, the system's real-time data display via Bluetooth, voice prompts, and data recording during indoor, ballless practice further help users improve their putting technique. By mastering the muscle memory required for putting speeds and putter face squareness at different distances, targeted practice will undoubtedly yield better results.

[0031] This portable intelligent golf putting practice system can be extended to two devices. One is a reflective type, designed for beginners. The ball is placed at the marked positions on the practice device to practice putting, experiencing the direction and distance of the putter, and building a solid foundation in putting technique. The other is a through-shot type, a U-shaped device, provided for experienced golfers. The ball can be placed directly on the green grass through the gaps in the U-shaped device for more precise putting.

[0032] This invention can instantly collect the putter's impact velocity and the clubface squareness before and after impact, i.e., the clubface deviation angle, and transmit the data via Bluetooth to a mobile phone or tablet for recording and data processing. The data is accurate and easy to use. The data collection sensor uses a proximity switch (inductive or capacitive). Taking an inductive proximity switch as an example, an oscillator generates an alternating magnetic field. When a metal object approaches this magnetic field and reaches the set sensing distance, eddy currents are generated within the metal target, causing the oscillator to attenuate and stop. The changes in oscillation and cessation are processed by a subsequent amplifier circuit and converted into a switching signal, triggering the drive controller to achieve non-contact detection. Data recording of the clubface impact velocity and clubface deviation angle allows for ballless training. It facilitates putting practice with or without a ball on the green and indoors / outdoors. Data storage and analysis: Putting data from 10 putts, 20 putts / sets, etc., can be analyzed and processed. This data includes putting speed errors (maximum, minimum, and average), the percentage and average error of the clubface deviation angle before and after each shot. Analyzing these multiple sets of historical data aims to uncover hidden technical gaps in the player's skills, such as issues related to short putts, long putts, green slope, and different green turf speeds.

[0033] This invention is small in size and lightweight. It can be conveniently used both indoors and outdoors.

[0034] This portable instrument allows users to conveniently practice putting by placing their ball on any desired position on the green with their preferred club. Putting parameters are instantly communicated verbally, including the ball speed (controlling the ball's roll distance) and clubface squareness (clubface deviation angle before and after impact). This data is transmitted via Bluetooth to the user's mobile phone or tablet for recording and statistical analysis. This data can provide effective technical improvement guidance for coaches and experienced golfers. Using this data as a reference, users can easily place the instrument indoors for ball-free practice during their free time (morning, noon, evening, and holidays), adapting to different green conditions and the muscle memory effect of putting. This significantly improves the user's putting technique. The putting data acquisition utilizes a proximity switch principle, ensuring high accuracy, sensitive response, and high reliability. This invention provides both the angle indication of the golf hole's direction and the fairway line direction, and the clubface angle deviation before and after impact, whereas existing products only record the clubface deviation before impact.

[0035] This utility model weighs only a few pounds and can be easily placed in a backpack.

[0036] This utility model can be used as an assistant for professional athletes to improve their training performance and as a tool for beginners to practice. It can be used for practice on outdoor actual combat fields and also as an indoor simulation practice tool. It can be used for practice with a ball and also for practice without a ball. This utility model has a wide range of uses, low cost, and good effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] The following further describes this utility model in conjunction with the drawings and embodiments.

[0050] Embodiment 1.

[0051] As Figure 1-11 shown.

[0052] A portable, multi-parameter intelligent training system for putting greens in golf is available. It is suitable for professional athletes or enthusiasts with some golf experience. Its external structure is as follows: Figure 1 As shown, the overall shape is U-shaped or π-shaped, and it includes:

[0053] A support frame 1 is provided for mounting electromagnetic induction sensor 2 and electronic control components, making the entire training system portable and mobile. In practice, to accommodate different training needs, the distance between the two sensing elements on each leg can be designed as adjustable to accommodate changes in user height. The distance between each set of sensing elements on the two legs is also designed as adjustable to accommodate different sizes of pole heads. For real-time compensation and accurate calculation, the support frame 1 can be positioned at any point... Figure 1 The first gyroscope 7 is installed at the bottom of the U-shaped support to detect its position slope and send it to the computer system as a basis for correction calculation so as to better adapt to putting practice in the green area.

[0054] A sensor 2 is installed on two legs of the bracket. At least two sensor 2s are installed on each leg. The two corresponding sensor 2s on the two legs form a set of electromagnetic induction sensing elements. The distance between each set of sensing elements is sufficient to ensure that the golf club head passes through smoothly and that the sensing elements on both legs can sense the change in electromagnetic signal. The speed and deflection angle of the putter head are calculated by calculating the time difference and intensity of the sensing signals received by the two sets of sensing elements.

[0055] An electronic control element 3 receives the signal strength and time difference obtained by the sensor element 2 and transmits it in real time via wired or wireless means to the computer system 4. After calculation and analysis, the speed and angle of the push rod are displayed in real time and compared with preset standard values ​​so that the coach or trainee can make improvements. In specific implementation, the computer system 4 can be a mobile phone, iPad, portable computer, or a display with computing functions.

[0056] To further meet the needs of advanced practitioners, several second gyroscopes (e.g., 8) can be installed on the shaft of the golf club during implementation. Figure 11 , Figure 11 A gyroscope is installed on both the center and the handle to monitor the clubhead's 3D attitude, clubface angle, and acceleration in real time.

[0057] Details are as follows:

[0058] like Figure 2-9 As shown.

[0059] The sensor device 2 includes a sensor array 100, such as... Figure 2As shown, in some embodiments, the sensor array 100 includes: a first sensor (S1) 1211, a second sensor (S2) 1212, a third sensor (S3) 1221, and a fourth sensor (S4) 1222. The first sensor 1211 and the second sensor 1212 are mounted on a first sensor support member 121. The third sensor 1221 and the fourth sensor 1222 are mounted on a second sensor support member 122. The first sensor 1211, the second sensor 1212, the third sensor 1221, and the fourth sensor 1222 form a rectangle. A golf ball 150 is placed at the center of the rectangle. The first sensor 1211 and the third sensor 1221 form a pre-hit reference line 160, and the second sensor 1212 and the fourth sensor 1222 form a post-hit reference line 162. As the golfer swings the putter 140 from right to left, passing the pre-impact reference line 160, striking the golf ball 150, and passing the post-impact reference line 162, the sensor array 100 collects putting practice data. The collected putting training data includes: the impact velocity of the putter 140, the impact angle 190 of the putter 140, and whether the impact face 143 of the putter 140 hits the optimal impact point 1431.

[0060] like Figure 2-5 As shown, when the putter 140 swings perpendicularly to the first sensor 25 support 121 and the second sensor support 122 from the pre-impact reference line 160 to the post-impact reference line 162, and the first distance D1 equals the third distance D3 and the second distance D2 equals the fourth distance D4, the striking face 143 of the putter 140 hits the sweet spot 1431 of the putter 140; while the golf ball 150 moves forward along a straight line 180.

[0061] like Figure 5-6 As shown, when the putter 140 swings from the pre-impact reference line 160 to the post-impact reference line 162, the striking face 143 of the putter 140 strikes the golf ball 150 along the proximity direction 182.

[0062] like Figure 5-7 As shown, when the putter 140 swings from the pre-hit reference line 160 to the post-hit reference line 162, the striking face 143 of the putter 140 strikes the golf ball 150 along the open direction 184.

[0063] In specific implementation, the sensor array 100 can be any of the following: a laser sensor, a set of optical sensors, a set of ultrasonic sensors, a set of electromagnetic sensors, or a combination of these sensors.

[0064] like Figure 4-7As shown, when the first end 141 of the putter 140 moves between the first sensor 1211 and the second sensor 1212, the time it takes for the first end 141 of the putter 140 to move between the first sensor 1211 and the second sensor 1212 determines the first striking speed of the putter 140. When the second end 142 of the putter 140 moves between the third sensor 1221 and the fourth sensor 1222, the time it takes for the second end 142 of the putter 140 to move between the third sensor 1221 and the fourth sensor 1222 determines the second striking speed of the putter 140. The striking speed of the putter 140 is the average of the first striking speed and the second striking speed of the putter 140. When the putter 140 swings from right to left across the pre-striking reference line 160 between the first sensor 1211 and the third sensor 1221, the first sensor 1211 and the third sensor 1221 detect the pre-striking angle 192 of the putter 140. When putter 140 is swung from right to left, passing through the post-impact reference line 162 between the second sensor 1212 and the fourth sensor 1222, the second sensor 1212 and the fourth sensor 1222 detect the post-impact angle 194 of putter 140. The impact angle 190 of putter 140 is the average of the pre-impact angle 192 and the post-impact angle 194 of putter 140.

[0065] like Figure 6As shown. When the putter 140 swings from right to left across the pre-impact reference line 160 between the first sensor 1211 and the third sensor 1221, the first sensor 1211 detects a first distance D1 between the first end 141 of the putter 140 and the first sensor 1211, and the third sensor 1221 detects a third distance D3 between the second end 142 of the putter 140 and the third sensor 1221. When the putter 140 swings from right to left across the post-impact reference line 162 between the second sensor 1212 and the fourth sensor 1222, the second sensor 1212 detects a second distance D2 between the first end 141 of the putter 140 and the second sensor 1212. The fourth sensor 1222 detects a fourth distance D4 between the second end 142 of the putter 140 and the fourth sensor 1222. When the first distance D1 equals the third distance D3 and the second distance D2 equals the fourth distance D4, the putter 140 hits the optimal impact point 1431. The impact velocity of putter 140 is the average of its first impact velocity and its second impact velocity. When putter 140 swings from right to left through the pre-impact reference line 160 between the first sensor 1211 and the third sensor 1221, the first and third sensors 1221 detect the pre-impact angle 192 of putter 140. When putter 140 swings from right to left through the post-impact reference line 162 between the second and fourth sensors 1212 and 1222, the second and fourth sensors 1222 detect the post-impact angle 194 of putter 140. The impact angle 190 of putter 140 is the average of its pre-impact angle 192 and its post-impact angle 194.

[0066] When the push rod 140 swings from right to left across the pre-impact reference line 160 between the first sensor 1211 and the third sensor 1221, the first sensor 1211 detects the first distance D1 between the first end 14110 of the push rod 140 and the first sensor 1211, and the third sensor 1221 detects the third distance D3 between the second end 142 of the push rod 140 and the third sensor 1221. When swinging putter 140, from right to left, through the postal strike reference line 162, between the second sensor and the fourth sensor in 1212 and 1222, the second sensor in 1212 detects the second distance D2 putter's first end between 141 and 140 to the second sensor in 1212, and the fourth sensor in 1222 detects the fourth distance D4 putter's second end between 142 and 140 to the fourth sensor in 1222. When the first distance D1 equals the third distance D3 and the second distance D2 equals the fourth distance D4, putter 140 hits the optimal striking point 1431 of putter 140.

[0067] In specific implementation, the communication networks 40 used include: Wi-Fi network, Bluetooth network, infrared network, Zigbee network, wireless local area network (WLAN), wireless metropolitan area network (WMAN), wireless wide area network (WWAN), cellular network, and mobile communication network.

[0068] In practice, the processing and display device, i.e., the mobile electronic device 30, includes the Apple iPad, mobile smartphones (such as the Apple iPhone operating the iOS operating system, Samsung smartphones, or any smartphone operating the Android operating system), tablet computers (such as the Microsoft Surface, Google Pixel tablet, Lenovo IdeaPadtablet, Samsung Galaxy Tab, or any other portable tablet computer).

[0069] Putting practice data can be displayed in real-time on the mobile electronic device 30 for the user to view during putting practice, and the audio output of the mobile electronic device 30 provides real-time guidance to improve putting practice. The user receives the audio output of the mobile electronic device 30 through an audio output device 34. The audio output device 34 of the mobile electronic device 30 includes the internal speaker of the mobile electronic device 30, wirelessly connected headphones, earbuds, earphones, and Apple AirPods.

[0070] Figure 9This invention utilizes the training system of this invention to display an exemplary report form 32 showing putting results during a round of putting. Before practicing putting, the user should enter certain information and goals for the upcoming practice. The information and goals for the putting practice include: the name of the putting participant, the date of the putting practice, the location of the putting practice, the expected putting speed (mph), greens percentage, golf course slope 10, the angle between the hole and the fairway, and the number of putting attempts per round. In one embodiment, the putting participant's name is John Doe, the date is October 15, 2023, the putting practice location is at home, the expected putting speed is 2.0 mph, the greens percentage is 6.3, and the slope includes: uphill: 2%, downhill: 3%, slope: 9%. The angle between the hole and the fairway is 32°. The number of putts per round is set to 20. The counter 35 is set to zero before the putting practice begins. The number of putts is displayed in column 320. After inputting their putting practice information and goals, participants can begin putting practice. A golf ball 150 is placed at the center of a rectangle in the sensor array 100. Once the golfer swings the putter 140 through the center of the rectangle in the sensor array 100, a counter 35 automatically increments by 1, detecting putting practice data and wirelessly transmitting it to a mobile electronic device 30. The time it takes for the first end 141 of the putter 140 to move 20 between the first sensor 1211 and the second sensor 1212 determines the first impact velocity of the putter 140. The time it takes for the second end 142 of the putter 140 to move between the third sensor 1221 and the fourth sensor 1222 determines the second impact velocity of the putter 140. The putting velocity is the average of the first impact velocity and the second impact velocity of the putter 140. The putting speed, in miles per hour (mph), is displayed in Table 32 of the Putting Practice 25 Results Report. When the putter 140 swings from right to left across the pre-impact reference line 160 between the first sensor 1211 and the third sensor 1221, the first and third sensors detect the pre-impact angle 192 of the putter 140. The pre-walk angle is displayed in the "Pre-walk Angle" column 322. In the pre-walk angle column 322, there are two sub-posts: an open sub-post 3221 and a closed sub-post 3222. The open sub-post 3221 and the closed sub-post 3222 indicate the current direction in the open direction 184 (e.g., ...). Figure 4 and 7 (As shown) or on closed-circuit direction 182 (e.g.) Figure 3 and 6(As shown). Since the putter 140 can only travel in one of two directions, the pre-travel angle 192 can only be displayed in one of the two sub-columns 3221 or 3222. When the putter 140 swings from right to left through the post-impact reference line 162 between the second sensor 1212 and the fourth sensor 1222, the second sensor 1212 and the fourth sensor 1222 detect the post-impact angle 194 of the putter 140. The pre-travel angle is displayed in the "Pre-travel Angle" column 322. In the pre-impact angle column 323, there are two sub-columns: open sub-column 3231 and closed sub-column 3232. The open sub-column 3231 and the closed sub-column 3232 indicate whether the current direction is in the open direction 184 (as shown in FIG3 and FIG6) or in the closed direction 182 (as shown in FIG2 and FIG5). Since the putter 140 can only travel in one of two directions, the post-stroke angle 194 can only be displayed in one of the two sub-columns 3231 or 3232. The post-stroke angle 190 of the putter 140 is the average of the pre-stroke angle 192 and the post-stroke angle 194 of the putter 140. When the putter 140 swings from right to left through the pre-stroke reference line 160 between the first sensor 1211 and the third sensor 1221, the first sensor 1211 detects a first distance D1 between the first end 141 of the putter 140 and the first sensor 1211, and the third sensor 1221 detects a third distance D3 between the second end 142 of the putter 140 and the third sensor 1221. The pre-stroke distance is defined as (D1-D3), or the first distance D1 minus the third distance D3. The pre-stroke distance is displayed in column 324, "Pre-stroke Distance". In the pre-walk distance column 324, there are two sub-columns: a downward sub-column 3241 and an upward sub-column 3242. The downward sub-column 3241 and the upward sub-column 3242 indicate whether the current strike is slightly below or slightly above the center of the sensor array 100. Since a single strike of the putter 140 can only occur in one of these two positions, the pre-walk distance (D1-D3) can only be displayed in one of the two sub-columns, 3241 or 3242. When the putter 140 swings from right to left across the post-strike reference line 162 between the second sensor 1212 and the fourth sensor 1222, the second sensor 1212 detects a second distance D2 between the first end 25 141 of the putter 140 and the second sensor 1212, and the fourth sensor 1222 detects a fourth distance D4 between the second end 142 of the putter 140 and the fourth sensor 1222. The post-strike distance is defined as (D2-D4), or the second distance D2 minus the fourth distance D4. The “Post-hit distance” column 325 displays the “pre-hit distance”. Within the post-hit distance column 325, there are two sub-columns: a down column 3251 and an up column 3252. The down column 3251 and the up column 3252 indicate whether the current impact was slightly below or slightly above the center of the sensor array 100.Since a single shot with putter 140 can only result in one of two positions, the post-shot distances (D2-D4) can only be displayed in one of the two sub-columns, 3251 or 3252. Putter 140 hits its optimal striking point 1431 when the first distance D1 equals the third distance D3, and the second distance D2 equals the fourth distance D4. After each shot with the golf ball 150, putter 140 wirelessly transmits the putter speed, pre-shot angle, post-shot angle, pre-shot distance, and post-shot distance to mobile electronic device 30, filling the putting practice results report table 32 on the display area of ​​mobile electronic device 30 and displaying it in the corresponding columns and sub-columns. Then, the putting practice participant receives voice prompts for the putter speed in mph, the shot angle 190 degrees in open or near direction, the putter position (whether the putter is down or up from the centerline), and the offset in inches. For example, as shown. Figure 8As shown, after the first putt, the voice feedback might include: "Good job, putting speed 2.20 mph, near-side angle 2.1 degrees, putt about 1 inch below the center line." This allows putting practice participants to review the result of the putt, hear the audio feedback, and make adjustments for the next putt to improve accuracy. After a predetermined number of putting shots, the statistics for the current putting data are calculated and displayed at the bottom of the putting results report 32. Row 326 shows the average offset of the putter drill data, and row 327 shows the percentage of the offset. The average offset of putting speed is displayed at the intersection of column 321 and row 326. The putting speed for this round of putting practice was 2.33 mph, calculated by averaging the speeds of all 20 putts in this round. The percentage of the putter speed offset is 16.50%, calculated using the formula (2.33 - 2.00) / 2.00. There are 12 open putts with an average open offset of 3.55, calculated as the average of all 12 open putts in degrees, displayed at the intersection of columns 3221 and 326, or 60% of putts were made in the open direction, displayed at the intersection of columns 3221 and 327. There are 8 close putts with an average close offset of 4.03, calculated as the average of all 8 close putts in degrees, displayed at the intersection of columns 3222 and 326, or 40% of putts were made in the close direction, displayed at the intersection of columns 3222 and 327. There are 6 backstrikings in the open direction with an average open offset of 3.78, calculated as the average of all 6 backstrikings in degrees, displayed at the intersection of columns 3231 and 326, or 30% of putts were made in the open direction, displayed at the intersection of columns 3231 and 327. There were 14 putts with a near-backward stroke, with an average near-backward offset of 5.85. This was calculated by averaging all 14 near-backward strokes and displayed at the intersection of column 3232 and row 326, or by showing a 70% near-backward stroke at the intersection of column 3232 and row 327. There were 11 putts that were below the center line of sensor array 100 after impact, with an average downward offset of 1.01 inches. This was calculated by averaging the downward offset of all 11 putts in inches and displayed at the intersection of column 3251 and column 326, or by showing a 55% near-backward stroke at the intersection of column 3251 and column 327. Seven putts were 5 strokes above the centerline of sensor array 100, with an average upward offset of 1.03 inches. This was calculated by averaging all seven pre-hit upward offsets in inches, shown at the intersection of columns 3252 and 326, or 35% of the pre-hit putts, shown at the intersection of columns 3252 and 327. Two putts (the 9th and 19th) were actually hit along the centerline of sensor array 100, meaning 10% of the putts hit the optimal impact point 1431 on putter 140.After each round of putting practice, the putting practice result report form 32 is saved in the mobile electronic device 30. Participants can analyze the saved putting practice data and statistics to improve their golf skills in future practice. On the other hand, the training method of this invention includes the following operations:

[0071] The putting system 10 is installed by the user on the green of a golf course or in an indoor putting practice area. The putting system 10 includes a sensor array 100, a putting data acquisition circuit 20, and a mobile electronic device 30.

[0072] Input is provided by the user on the mobile electronic device 30, including putting practice information and objectives. This information and objectives include: participant's name, date of the practice, location of the practice, expected putting speed (20 degrees, miles per hour), green percentage, golf course slope, angle between the hole and the fairway, and number of putts per round.

[0073] The user begins putting practice by setting the counter from 35 to 0 and swings the golf ball 150, positioned from right to left at the center of the sensor array 100, along with the gold putter 140.

[0074] The putter data acquisition circuit 20 collects putter data 25 after each shot by the putter 140 via sensor array 100. The putter data includes the shot speed of the putter 140, the shot angle 190 of the putter 140, and whether the shot face 143 of the putter 140 hits the optimal shot point 1431 of the putter 140. After each putter shot, the counter 35 increments by 1, and the putter data acquisition circuit 20 collects putter drill data after the shot via sensor array 100, processes the putter drill data, and reports it to the user via mobile electronic device 30, providing feedback to the user in an audio or visual manner.

[0075] The mobile electronic device 30 displays statistics of the current round of putter drill data after each putter stroke 140, allowing the user to review the data and providing audio and video feedback to improve future putter drills.

[0076] When the counter 35 of the mobile electronic device 30 has not reached the number of hits per round, the step of collecting push rod data continues;

[0077] When the counter 35 of the mobile electronic device 30 reaches the number of shots per round, the user is asked whether to continue putting practice or end it.

[0078] When a user chooses to continue putting practice, another round of putting practice will begin.

[0079] The method ends when the user chooses to terminate the putting practice.

[0080] The detection distance of a proximity electromagnetic sensor can be determined through design. The design involves placing two sensors opposite each other at a distance from each other, without them touching. This distance is greater than the diameter of a golf ball but less than the width of a golf putter head. Therefore, when the putter strikes the golf ball on the green, the timing of the contact between the two oppositely placed sensors on either side of the putter face is simultaneously measured, allowing the calculation of the angle of deviation between the putter face and the target line.

[0081] This invention is a portable, battery-powered device. Therefore, it allows for putting practice on any position on the green, achieving accurate putting parameter measurements. The inductive proximity switch has a response frequency range of 500-600Hz, with customizable frequency response. It can calculate the putter's clubface trajectory in real time, indicating whether it deviates left or right and the clubface deflection angle. It can calculate the clubface movement speed and determine whether the sweet spot has been hit based on the proximity switch sensor status. Real-time data display, including the putting trajectory and related parameters, is shown on the mobile device.

[0082] The gyroscope mounted on the bracket can use the MPU6050 to detect green slope and estimate putting yardage based on distance. The gyroscope mounted on the golf club shaft can monitor the clubhead's 3D attitude, clubface angle, and acceleration in real time.

[0083] Figure 10 This is a hardware architecture diagram for a golf putting training system. The hardware consists of a Bluetooth communication module, a power supply module, a display module, and a signal sampling module.

[0084] The main control module can be implemented using conventional components, such as the STM32F401xC device based on a high-performance Arm Cortex-M4 32-bit RISC core, operating at frequencies up to 84MHz. The Cortex-M4 core features a single-precision floating-point unit (FPU) supporting all Arm single-precision data processing instructions and data types. It also implements a complete set of DSP instructions and a memory protection unit (MPU) to enhance application security. The STM32F401xB / STM32F401xC integrates high-speed embedded memory (up to 256KB of Flash memory and up to 64KB of SRAM), as well as extensive enhanced I / O and peripherals, connecting to two APB buses, two AHB buses, and a 32-bit multi-AHB bus matrix. All devices provide a 12-bit ADC, a low-power RTC, six general-purpose 16-bit timers (including a PWM timer for motor control), and two general-purpose 32-bit timers. They also feature standard and advanced communication interfaces. The STM32F401xB / STM32F401xC operates over a temperature range of -40 to +125°C and supplies power from 1.7V (PDR OFF) to 3.6V. A comprehensive suite of power-saving modes allows for the design of low-power applications.

[0085] The power module of this invention can also be designed using conventional circuits. It is powered by a 12V lithium battery, which powers the main control module, sensor module, and communication module. The 12V to 5V converter uses the TPS5450, a high-output-current PWM converter, and the 5V to 3.3V converter uses the AMS117 power chip.

[0086] The communication module uses the HLK-B40 Bluetooth module, which supports the BLE Bluetooth 5.1 protocol, has a main frequency of 48MHz, a 32-bit ARM Cortex M3 core, and is a master-slave integrated module. It can be set to master or slave mode, supports binding encryption, has an ultra-long transmission distance of 40-100m in open environments, a low power consumption mode with a minimum sleep current of 6μA, and an ultra-small size of only 14mm×9.5mm×2mm. Bluetooth specifications: BLE 5.1 / L2CAP / ATT / GAP / HID.

[0087] The electromagnetic induction head consists of a magnetic core and enameled wire, capable of detecting metallic objects within 25mm, with a response time of <0.5ms, a switching frequency of 1000Hz, stable performance, and resistance to both heat and low temperatures. It can operate normally in environments ranging from -25℃ to 70℃, making it suitable for both outdoor and indoor equipment. It exhibits minimal temperature drift and high detection accuracy.

[0088] The software system adopts a front-end / back-end separation model. The front-end is based on Vue and Element-UI, while the back-end uses the Spring Cloud suite. The basic components are highly encapsulated and a separate open-source framework, BladeTool, has been released. BladeTool is pushed to the Maven Central Repository for direct import, reducing project bloat and allowing for greater focus on business development integration with Sentinel to protect service stability from multiple dimensions, including traffic control, circuit breaking, and system load balancing. Nacos is chosen for the registry and configuration center, slimming down the project while strengthening the interaction between modules. Traefik is used for reverse proxying, automatically updating configuration files to monitor backend changes. A minimalist multi-tenant underlying layer is encapsulated, achieving a more scalable SaaS multi-tenant system with less code. Borrowing from OAuth2, a multi-terminal authentication system is implemented, allowing for controllable token permission isolation between subsystems. Borrowing from Security, the Secure module is encapsulated, using JWT for token authentication, and can be extended to integrate with fine-grained control solutions such as Redis.

[0089] The hardware programming language is C, and the development tools used are Keil v5 for compilation, debugging, and flashing Arm Keil microcontrollers. The Keil microcontroller toolkit includes a C / C++ compiler, integrated development environment (IDE), RTOS, middleware, and tools for... The debugging adapter and evaluation board circuit design tools for the equipment use Altium 18.

Figure 12 As shown, it includes a mounting plate 9, characterized in that: two sets of four electromagnetic induction sensing elements 10 are mounted on the mounting plate 9. The electromagnetic induction sensing elements 10 are used in pairs to sense changes in the electromagnetic signal as the golf club head passes by. The speed and deflection angle of the putter head are calculated by calculating the time difference and intensity of the signals received by the two sets of sensing elements. The mounting plate 9 also includes a main control board, a gyroscope, a battery, and other supporting electrical components 11, as well as a display. Preferably, the components are arranged in an H-shape, with the four electromagnetic induction sensing elements 10 arranged at both ends of the two vertical sides of the H-shape, and the main control board, gyroscope, and battery arranged on the horizontal bar of the H-shape.
