[0036] The wearable device connects to the Bluetooth module of the data relay device via a hardware communication module. The data relay device then connects to the server communication module of the data receiving device via the WIFI module of the data receiving device and stores the data. Finally, the data display device connects to the data receiving device via a mobile communication module to acquire and display the data.
[0037] The hardware communication module and the box's Bluetooth module are both low-power Bluetooth communication modules; the box's WIFI module, server communication module, and mobile terminal communication module are all standard wireless network communication modules.
[0038] The entire wearable device includes a heart rate base 6, a wrist strap 7, and a data acquisition device 1. One end of the data acquisition device 1 is provided with a first spring pin 102. The surface of the heart rate base 6 is provided with a heart rate mounting groove 603, and the surface of the wrist strap 7 is provided with a wrist mounting groove 701. Both the wrist mounting groove 701 and the heart rate mounting groove 603 are engaged with the back of the data acquisition device 1, and the size of the data acquisition device 1 is adapted to the size of the wrist mounting groove 701 and the heart rate mounting groove 603. The surface of the heart rate base 6 is provided with a magnetic card block 602, and the surface of the magnetic card block 602 is magnetically connected to a magnetic card holder 601. The surface of the magnetic card holder 601 is connected to a chest mounting strap 5. The end of the wrist strap 7 is connected to a wrist strap 9. The ends of the surfaces of the wrist strap 9 and the chest strap 5 are both provided with Velcro positioning stickers 8. The data acquisition device 1 contains an accelerometer, a gyroscope, and a heart rate sensor.
[0039] The heart rate base 6 is installed with the data acquisition device 1 via the heart rate mounting groove 603 on its surface. During installation, since one end of the heart rate mounting groove 603 of the heart rate base 6 has a third spring pin 606, and the edge of the third spring pin 606 has a third magnet 605, the third spring pin 606 corresponds one-to-one with the first spring pin 102. The third spring pin 606 is installed in correspondence with the first spring pin 102 at the end of the data acquisition device 1, and is magnetically positioned by the third magnet 605 to ensure the installation at the end. A fourth spring pin 607 is located near the center of the bottom surface of the heart rate mounting groove 603, and the fourth spring pin 607 corresponds to the second spring pin 103. A second magnet is located near the edge of the bottom surface of the heart rate mounting groove 603. Iron 604, the second magnet 604 and the first magnet 104 are magnetically connected. At the same time, the fourth spring pin 607 at the bottom of the heart rate mounting slot 603 corresponds to and abuts against the second spring pin 103 of the data acquisition device 1. The second magnet 604 and the first magnet 104 are attracted to each other for positioning, completing the installation of the entire data acquisition device 1 on the surface of the heart rate base 6. Then, the magnetic card holder 601 on the surface of the chest mounting strap 5 is installed in correspondence with the magnetic card block 602 on the surface of the heart rate base 6 to cover the surface of the data acquisition device 1, realizing the installation of the heart rate base 6 and the chest mounting strap 5. The chest mounting strap 5 is installed in correspondence with the user's chest, and the end is positioned using the Velcro positioning tape 8 to complete the wearing.
[0040] A second spring pin 103 is located at the center of the back of the data acquisition device 1. A first magnet 104 is located on the back of the data acquisition device 1 away from the first spring pin 102. A data acquisition indicator light 101 is located on the front of the data acquisition device 1. Velcro straps 702 are symmetrically arranged on both sides of the inner wall of the wrist mounting groove 701, with adjacent Velcro straps 702 on the same side interlocking. A Velcro tab 703 is located at one edge of the wrist mounting groove 701 and is attached to the surface of the Velcro strap 702. The surface of the data acquisition indicator light 101 has R, H, and L indicator lights, representing the left side, heart rate, and right side, respectively. The data acquisition device 1 has three sets of indicator lights, each corresponding to a different heart rate. The base 6 and wrist strap 7 are installed. The wrist strap 7 has "R" and "L" markings inside the wrist mounting groove 701 for user identification. The data acquisition device 1 is placed inside the wrist mounting groove 701, and the two ends of the Velcro strap 702 are glued together. Finally, the Velcro tab 703 is glued to the surface of the Velcro strap 702 to install the data acquisition device 1 on the surface of the wrist strap 7. The wrist strap 7 has a positioning hole 704 near the end. The width of the positioning hole 704 is the same as the width of the wrist strap 9. The wrist strap 9 is passed through the positioning hole 704 and the end is glued using the Velcro positioning tab 8 on the surface to achieve wearing on the user's wrist.
[0041] During data acquisition: Data acquisition device 1 acquires arm acceleration data using an accelerometer, arm rotational angular velocity data using a gyroscope, timestamp data using a clock module, and heart rate data of the subject using a heart rate sensor. Data acquisition device 1 calculates the punching technique, speed, force, and power of the punching process based on the preset weight of the subject's arm using accelerometer and gyroscope data. Data acquisition device 1 then uploads the heart rate, punching technique, acceleration, speed, force, and power to the data transfer device.
[0042] When the component is used for boxing, the data acquisition device 1 is tightly fixed to the wrist with a strap, and the chest strap is worn at the lower edge of the chest. In actual training, boxers will wrap a strap around their wrists to protect them, so the extra strap we wear will not affect the athlete's training. Specific Implementation Example 2:
[0044] Reference Figure 1-12 Based on the content of the above specific embodiments, the following content is further disclosed:
[0045] In actual use, the entire device is designed to facilitate use and management by multiple users, such as... Figure 8 As shown, the control box has 60 slots. Place the wearable device into the slot, click the ID button to assign an ID to all wearable devices, and then assign three devices to each user in the same group. Each device has three indicator lights: "L" - left, "R" - right, and "H" - heart rate. The user inserts the devices indicating "L" and "R" into the straps on the user's left and right hands, respectively, and inserts the device indicating "H" into the heart rate base 6. Then, attach the chest strap to the user's body, and the user starts exercising. The device begins to record the user's punching data and heart rate data.
[0046] like Figure 8 As shown, the meanings of the indicator lights and buttons on the control box are as follows:
[0047] When the control box is in charging mode, the charging indicator light remains on.
[0048] When configuring basic information by connecting a mobile phone to the control box via Bluetooth, the Bluetooth indicator light will remain on.
[0049] When a successful Wi-Fi connection to the server is established, the Wi-Fi light remains on.
[0050] When a 4G connection to the server is successfully established, the 4G light will remain on.
[0051] When a LAN connection to the server is successfully established, the LAN light remains on.
[0052] When the wearable device is returned to the box and a new ID needs to be assigned, click the ID button;
[0053] When the wearable device is placed back in the box and data interaction is required, click the history button; press and hold the power button to start or stop the control box.
[0054] If the control box and equipment become disconnected, you can press the reset button to re-establish the connection. Specific Implementation Example 3:
[0056] Reference Figure 1-12 Based on the content of the above specific embodiments, the following content is further disclosed:
[0057] The data acquisition device 1 has a built-in battery, MCU, LDO, and SPI. The battery voltage is converted by the LDO to power the chip inside the data acquisition device 1. The MCU is a microcontroller unit that receives data collected by the sensors. It reads the data collected by the sensors and calculates punch technique, acceleration, speed, force, and power. Then, it sends the punch technique, acceleration, speed, force, and power to the data relay device in real time via the Bluetooth communication module. The data relay device uploads the data to the data receiving device in real time via the box's WIFI module. The data receiving device saves the data to the data storage module. The data display device reads the data from the data receiving device and displays it in real time.
[0058] The data transfer device is a control box containing a Bluetooth module, a WIFI module, and a hardware charging module. Each box contains 60 slots for placing wearable devices. Each user wears three devices in the same group, achieving the effect of real-time data collection from 20 people. The data acquisition device 1 is magnetically attached to the control box via the first spring pin 102 at its end, realizing charging and data interaction between the device and the control box. When the device is attached to the control box, the control box sends instructions to the device via the ID button, realizing the reassignment of the device's ID and function.
[0059] The data receiving device is a server containing a WIFI module, and a system responsible for computing and storage functions runs on the data receiving device.
[0060] The data display device is a mobile device such as a tablet or smartphone with Wi-Fi capability, and it contains an app that displays the data. The mobile device will issue a warning if the heart rate remains above the safe threshold for an extended period.
[0061] When the Bluetooth connection between the data acquisition device 1 worn on the wrist and the data relay device is lost, or when the data acquisition device 1 fails to find a data relay device to connect to, or when no punch is detected for a long time, the data acquisition device 1 will enter a sleep state. When the data acquisition device 1 in the sleep state is shaken, the data acquisition device 1 will be woken up and perform Bluetooth pairing.
[0062] When the Bluetooth connection between the data acquisition device 1 worn on the lower edge of the chest and the data relay device is lost, or when the data acquisition device 1 fails to find a connectable data relay device, or when the heart rate is not detected for a long time, the data acquisition device 1 will enter a sleep state. When the heart rate is detected or a connectable data relay device is available, the data acquisition device 1 will be woken up and perform Bluetooth pairing.
[0063] When the Bluetooth connection between the data acquisition device 1 and the data relay device is lost, the data acquisition device 1 can be resent via the reset button on the control box. After receiving the reset signal, the data acquisition device 1 will re-pair with the device relay module via Bluetooth.
[0064] In this invention, the data acquisition device 1 also includes a data storage function. When the communication between the data acquisition device 1 and the data relay device is disconnected, the data acquired by the data acquisition device 1 can be temporarily stored in the acquisition device. After the training is completed, when the data acquisition device 1 is placed back into the control box of the data relay device, the data relay device will read the data from the data acquisition device 1 and upload the data to the data receiving device, thereby greatly improving the adaptability to communication quality.
[0065] The gyroscope is a three-axis gyroscope; because boxers punch very fast, in order to prevent the acceleration from exceeding the range of the accelerometer, the accelerometer contains two types of accelerometer sensors: a 16g three-axis accelerometer and a 200g three-axis accelerometer.
[0066] In this invention, the data acquisition device 1 worn on the wrist enters sleep mode when Bluetooth is interrupted, there is no Bluetooth connection, or no punch is detected for an extended period. The sleep-activated data acquisition device 1 can be woken up by shaking. This design aligns with the characteristics of boxing; athletes simply wear the data acquisition device 1 on their wrist and throw a punch to begin real-time data collection, greatly improving ease of use. During breaks or after exercise, the data acquisition device 1 automatically enters sleep mode, extending its battery life. Even after breaks or after exercise, the data acquisition device 1 worn on the chest continues to send heart rate data to the data relay device, ensuring that the athlete's heart rate data during training and recovery is not lost.
[0067] In this invention, the data acquisition device 1 is a wristband or chest strap worn on the wrist or chest. In actual combat, the chest strap can also be fixed to the back to avoid the striking points of boxing. By measuring speed and force using an accelerometer, the data acquisition device 1 can measure striking data without being squeezed; thus, it will not cause injury to athletes due to the hard outer shell of the device, and it can also extend the service life of the device.
[0068] In this invention, the data acquisition device 1 calculates the force value based on the weight of the person's arm. If the arm weight is unknown, it is calculated based on body weight. Generally, the arm weight of a male is 0.057% of his body weight, and the arm weight of a female is 0.0497% of her body weight. This design greatly expands the application field of this invention. For example, by using the data acquisition device 1 fixed to the ankle, the force of a kick can be calculated. The calculated striking force value is data reflected by biomechanics, which is more in line with the characteristics of combat sports.
[0069] In this invention, all test data are uploaded to the server via Bluetooth and WIFI in sequence, and then displayed on the mobile device. The server has storage function, which is beneficial for coaches to use the data for horizontal and vertical comparison, thereby judging the training results and giving athletes training advice in a timely manner. This makes this invention easy to implement and promote. In addition to boxing, it can be used in combat sports such as taekwondo and sanda.
[0070] In this invention, the data acquisition device 1 is independent of the boxing gloves. The data acquisition device 1 is fixed to the placement slot of the strap in a replaceable manner, which makes it easier to replace and maintain. At the same time, by changing the shape and size of the strap, it can be adapted to the data acquisition and display work of athletes of different ages and different events.
[0071] In this invention, the sensor processes the collected data through the MCU to calculate the punch technique, speed, force, and power. Then, the collected data, punch technique, acceleration, speed, force, and power are uploaded to the data receiving device in real time through a data relay. This design enhances the real-time performance of the data. Because the movements in boxing are very fast, in order to achieve the goal of accurate calculation, when the data is detected as a punching action, the MCU immediately processes the data and uploads the results, ensuring the accuracy of the collected data and calculation results.
[0072] This product can temporarily store the raw data from the accelerometer and gyroscope. After being placed back into the slot of the control box, it interacts with the control box to send this raw data to the server of the data receiving device. Researchers can then use this data to reproduce the trajectory, angle, and other details of a punch, and can also view the action from different angles through 3D modeling, which is of great help to sports training.
[0073] In summary:
[0074] The device employs an internal accelerometer, gyroscope, and heart rate sensor in its data acquisition unit 1 to monitor user data. It is attached to the user's wrist with a wrist strap 7 and a wrist band 9, and to the chest with a heart rate base 6 and a chest strap 5. This allows for the simultaneous acquisition of data from multiple athletes. Through data interaction with software, it enables real-time calculation and display of indicators such as heart rate and punching technique, regardless of location or time. This makes it easier for athletes and coaches to use, changing the traditional monitoring device worn on sports equipment. It is worn on various parts of the user's body, providing accurate monitoring data, is easy to wear, suitable for large-scale athlete monitoring, and highly scalable.
