Description

Technical Field

[0001] The present invention relates to the technical field of sports training monitoring, and particularly to an arm muscle fatigue monitoring and training device. Background Art

[0002] In the field of archery training, accurate muscle state monitoring is a core element to help athletes achieve breakthroughs in competitive levels and effectively avoid the risk of injury. The sport of archery has an extraordinary degree of dependence on the upper limb muscles. Accurately controlling the muscle state is of great significance for improving the competitive level. In high-intensity competitions, subtle differences in muscle state may lead to huge differences in performance. When the muscles are in the best state, athletes can complete the actions of drawing the bow, aiming, and releasing the arrow more stably and accurately, increasing the probability of the arrow hitting the bullseye. At the same time, accurate muscle state monitoring helps athletes adjust the training intensity and methods in a timely manner during training, avoiding the accumulation of muscle fatigue caused by overtraining, and thus always maintaining a good competitive state. From the perspective of reducing the risk of injury, real-time mastery of the muscle state can detect early signs of muscle fatigue in advance, such as abnormal muscle electrical activity and reduced blood oxygen content, and adjust the training arrangement in a timely manner to prevent sports injuries such as muscle strains and strains caused by excessive fatigue, providing a solid health guarantee for the long-term training and competitive career of athletes. Therefore, an arm muscle fatigue monitoring and training device is designed.

[0003] In terms of data acquisition, it is difficult for the existing technology to achieve comprehensive and accurate data acquisition. Most traditional monitoring devices can only focus on a single indicator, such as a simple heart rate monitoring device, and cannot give intuitive reminders in a timely and accurate manner when the athlete's muscles are in a fatigued state or the movement posture is abnormal.

[0014] In at least some embodiments, The upper arm micro pressure sensor inside the circumferential elastic adjustment band, the angle sensor inside the elbow guard plate, and the lower arm micro pressure sensor inside the elastic magic tape are all electrically connected to the processor inside the upper arm main body.

[0015] The present invention provides an arm muscle fatigue monitoring and training device, which has the following beneficial effects: In the present invention, multiple electromyography sensors are used to collect muscle electrical activity signals, combined with near-infrared spectroscopy sensors to monitor the blood oxygen content of muscle tissues, pressure sensors are used to sense the pressure changes of the arm, and angle sensors are used to monitor the bending angle of the elbow joint. Multiple sensors work together to obtain data from multiple dimensions, greatly improving the comprehensiveness and accuracy of muscle fatigue monitoring, enabling athletes and coaches to timely and accurately grasp the muscle state, and laying a solid foundation for scientifically adjusting training strategies.

[0016] In addition, in the present invention, a Freescale Kinetis series microprocessor with powerful data processing capabilities is adopted to perform real-time and rapid processing and analysis on a large amount of complex sensor data. The low-noise operational amplifier chip and analog-to-digital conversion chip in the data processing and transmission module further optimize the signal processing process to ensure high-quality transmission and conversion of data. At the same time, data interaction with external devices is achieved through a Bluetooth 5.0 chip, facilitating athletes and coaches to view key information such as muscle fatigue degree and training status in real time on intelligent terminals such as mobile phones and computers, presented in an intuitive manner such as charts and color changes, which is clear at a glance. In addition, the interaction module supports receiving control instructions sent by external devices to achieve remote control of the device, such as adjusting the tactile feedback intensity, frequency, etc., significantly improving the convenience and interactivity of the device.

[0017] The solar power supply module equipped in this device selects high-efficiency monocrystalline silicon solar panels, which have a high photoelectric conversion efficiency. In an environment with sufficient light, the solar panels can efficiently convert solar energy into electrical energy. On the one hand, it directly powers each electrical component of the device to maintain the stable operation of the device; on the other hand, it charges the built-in rechargeable lithium polymer battery, effectively extending the battery life of the device and greatly reducing the dependence on external power sources. This feature makes the device have significant advantages in outdoor training scenarios, getting rid of the limitation of power sockets and providing athletes with a more free training space. The photoresistive light sensor mounted on the induction plate can sensitively detect changes in the ambient light intensity. When the light intensity changes, the light sensor transmits a signal to the control circuit. When the light is sufficient, the control circuit drives the motor to operate. The output shaft of the motor is connected to the rotating column, and the pulley on the rotating column drives another rotating column to rotate synchronously through the connecting belt. At the same time, the rotation of the rotating column pushes the induction plate mounted on the upper ends of the four groups of sliders to open to the left through the connecting belt clamped by the first clamping plate and the second clamping plate, enabling the solar panels to fully absorb light energy. When the light is poor, the light intensity detected by the photoresistive light sensor is lower than the preset threshold, and then it transmits a corresponding signal to the control circuit and makes the motor reverse. The reverse rotation of the motor drives the rotating column to rotate in the opposite direction, and the induction plate is pulled back to the initial position through the connecting belt until the induction plate is completely closed. After the induction plate is closed, it can effectively block external impurities such as dust and water vapor from entering, playing a good protective role for the internal solar power supply module.

[0018] In addition, in the present invention, the tactile feedback system in the mechanical data memory uses an STM32 series microcontroller as the tactile feedback controller, and controls the piezoelectric ceramic sheet made of lead zirconate titanate material as the tactile feedback actuator, which can timely and accurately transmit tactile feedback to the user when the processor determines that the muscle is in a fatigued state or the movement posture is abnormal, giving an intuitive reminder to avoid muscle injuries caused by overtraining or incorrect movements.

[0019] In addition, in the present invention, the unique design of the peripheral electromyography sensor and the patch provides great convenience for the user. The patch is made of flexible silicone material, which fits the human skin and is comfortable and durable. The peripheral electromyography sensor is installed on the patch. The user can flexibly paste the patch and the peripheral electromyography sensor at other positions on the body that need to be detected according to their own needs, breaking through the limitation of the fixed position detection of the device itself, so as to realize the accurate acquisition of the muscle electrical activity signals of multiple parts of the body. Whether it is to monitor the muscle force of different parts during sports training or to evaluate the recovery status of specific muscle groups in the medical rehabilitation scenario, this expandable detection range can provide more comprehensive and targeted data support for professionals, greatly enhancing the practicality and application value of the device.

[0026] In the present invention, Inside the upper arm main body 1, a solar power supply module is installed. The solar power supply module is electrically connected to the power supply in the mechanical data memory 121. The solar power supply module uses an efficient monocrystalline silicon solar panel. And on the upper arm main body 1, an induction plate 15 is installed. On the induction plate 15, a light sensor 151 is installed. The light sensor 151 selects a photoresistive sensor. The solar power supply module inside the upper arm main body 1 is located below the induction plate 15. Inside the upper arm main body 1, a first side plate 152 and a second side plate 153 are fixed. Between the first side plate 152 and the second side plate 153, two rotating columns 154 are installed through bearings. On both of the two rotating columns 154, two pulleys are fixed. Between the pulleys on the two rotating columns 154, a connecting belt 1541 is connected. Inside the upper arm main body 1, two groups of slide rails 155 are installed by screws. On both of the two groups of slide rails 155, two groups of sliders 1551 slide. The sliders 1551 are made of polytetrafluoroethylene. On the sliders 1551, a mounting plate 1552 is installed. At the lower end of the mounting plate 1552, a first clamping plate 1553 is fixed. At the lower end of the first clamping plate 1553, a second clamping plate 1554 is installed by bolts. The connecting belt 1541 is clamped between the first clamping plate 1553 and the second clamping plate 1554. The induction plate 15 is installed at the upper ends of the four groups of sliders 1551. And on the first side plate 152, a motor 1521 is installed. The output shaft of the motor 1521 is connected to the rotating column 154 near the left side of the first clamping plate 1553. Its functions are as follows: The solar power supply module composed of an efficient monocrystalline silicon solar panel is installed inside the upper arm main body 1. When the device is in a lighted environment, this module works, efficiently converts solar energy into electrical energy, and is electrically connected to the power supply in the mechanical data memory 121 to charge it, supplementing the electrical energy required for the device to operate. This process reduces the consumption of the self-power of the lithium polymer battery built in the mechanical data memory 121, improves the endurance of the device, and reduces the trouble of frequent charging. The photoresistive light sensor 151 carried on the induction plate 15 can keenly sense the change in the ambient light intensity. When the light intensity changes, the light sensor 151 transmits a signal to the control circuit. When the light is sufficient, the control circuit drives the motor 1521 to operate. The output shaft of the motor 1521 is connected to the rotating column 154. The pulleys on the rotating column 154 drive another rotating column 154 to rotate synchronously through the connecting belt 1541. At the same time, the rotation of the rotating column 154, through the connecting belt 1541 clamped by the first clamping plate 1553 and the second clamping plate 1554, pushes the induction plate 15 installed at the upper ends of the four groups of sliders 1551 to open to the left, so that the solar panel located below the induction plate 15 can fully absorb light energy. And when the light is poor, the light intensity detected by the photoresistive light sensor 151 is lower than the preset threshold, and then it transmits a corresponding signal to the control circuit and makes the motor 1521 reverse. The reverse rotation of the motor 1521 drives the rotating column 154 to rotate in the reverse direction, and through the connecting belt 1541, pulls the induction plate 15 to move to the initial position.Until the induction plate 15 is completely closed, after the induction plate 15 is closed, it can effectively block the entry of external impurities such as dust and water vapor, playing a good protective role for the internal solar power supply module.

[0027] In the present invention, At the rear end of the upper arm main body 1, a back plate 16 is snap-mounted. Two groups of mounting cylinders 161 are fixed on the back plate 16. Inside each mounting cylinder 161, a mounting seat 1611 is installed. Inside the mounting seat 1611, an inner ring 1612 is provided. The inner ring 1612 is made of polyoxymethylene material. Inside the inner ring 1612, a movable ball seat 1613 is installed. The movable ball seat 1613 is made of silicone material. A through hole is provided on the movable ball seat 1613. Inside the through hole on the movable ball seat 1613, a contact terminal 1614 is installed. Inside the two contact terminals 1614, an upper arm electromyography sensor and an upper arm near-infrared spectroscopy sensor are respectively provided. Both the upper arm electromyography sensor and the upper arm near-infrared spectroscopy sensor are electrically connected to a processor inside the upper arm main body 1. Their functions are as follows: The inner ring 1612 inside the mounting seat 1611 is made of polyoxymethylene material, which has good mechanical strength and wear resistance and can stably support the internal movable ball seat 1613. The movable ball seat 1613 is made of silicone material, which is soft and has a certain elasticity. Its special spherical structure enables the contact terminal 1614 installed in the through hole on it to move and adjust at a certain angle. This design allows the upper arm electromyography sensor and the upper arm near-infrared spectroscopy sensor installed in the contact terminal 1614 to flexibly adjust the angle according to the different shapes of the human upper arm and the movement changes of the user during wearing, and always maintain good contact with the skin, ensuring that the sensors stably and accurately collect data. The upper arm electromyography sensor can accurately collect the electrical activity signals of the upper arm muscles. These signals reflect the contraction and relaxation states of the muscles and can be used to analyze information such as muscle movement patterns and fatigue levels. The upper arm near-infrared spectroscopy sensor can obtain key data such as muscle blood oxygen content by detecting the absorption and scattering of near-infrared light by the upper arm tissue. The two work together to provide rich and accurate data support for comprehensively evaluating the physiological state of the upper arm muscles. Both the upper arm electromyography sensor and the upper arm near-infrared spectroscopy sensor are electrically connected to a processor inside the upper arm main body 1.

The outer wear-resistant layer 21 is made of a high-strength aramid fiber composite material. The elbow guard plate 2 is made of silicone rubber material. An angle sensor for monitoring the bending angle of the elbow joint is integrated in the elbow guard plate 2. Its functions are as follows: The upper arm micro pressure sensor integrated in the circumferential elastic adjustment band 12 can monitor the pressure on the upper arm in real time. Since the adjustment band is made of a blended material of spandex and nylon and has good elasticity, it can fit different parts of the upper arm during wearing. The micro pressure sensor can accurately sense the pressure change between the adjustment band and the upper arm, providing a comfortable wearing experience for the user on the one hand and avoiding affecting the use feeling due to excessive or too little pressure. The angle sensor integrated in the elbow guard plate 2 for monitoring the bending angle of the elbow joint can accurately measure the bending degree of the elbow joint in real time. During sports training, the data of the angle sensor can help athletes understand the standardization and accuracy of their own movements.

By monitoring the pressure change, the force distribution of the lower arm in different activity states can be understood, providing data support for evaluating the working load of the lower arm muscles. The lower arm electromyography sensor and the lower arm near-infrared spectroscopy sensor arranged in the lower arm main body 3 are respectively used for collecting the electrical activity signal of the lower arm muscles and the blood oxygen content information of the muscle tissue. These data are of great significance for understanding the functional state, fatigue degree and blood circulation condition of the lower arm muscles. The lower arm electromyography sensor can reflect the contraction and relaxation of the muscles, while the lower arm near-infrared spectroscopy sensor can provide the oxygenation state information of the muscle tissue. The data collected by these sensors are electrically connected to the processor inside the upper arm main body 1 and transmitted to the processor for processing and analysis. Finally, they can interact with external devices through a wireless communication module, providing a scientific basis for sports training, rehabilitation treatment, etc.

[0030] In the present invention, Inside the mechanical data storage 121, there is a tactile feedback system, which includes a tactile feedback controller and a tactile feedback actuator. The tactile feedback actuator is a piezoelectric ceramic sheet, which is made of lead zirconate titanate material. The tactile feedback controller uses an STM32 series microcontroller. Its function is as follows: When the device monitors data changes related to muscle fatigue, training abnormalities, or other preset conditions, the processor inside the upper arm main body 1 will transmit the corresponding signal to the tactile feedback controller of the tactile feedback system. With its powerful computing and processing capabilities, the controller quickly analyzes and processes the received signal. Subsequently, according to the pre-set program logic, it issues an instruction to the tactile feedback actuator. After receiving the electrical signal, the piezoelectric ceramic sheet can quickly generate mechanical deformation, thereby generating tactile feedback. This immediate tactile feedback can directly remind the user. For example, when the muscle reaches the fatigue threshold, the user can perceive it in time through the sense of touch without constantly paying attention to the display screen 11, so as to be able to adjust the state in time during exercise or training and avoid injuries caused by excessive fatigue.

[0031] Embodiment 2, on the basis of Embodiment 1, The processor inside the upper arm main body 1 is also provided with a data processing and transmission module and an interaction module.

The signal amplifier uses a low-noise operational amplifier chip, and the signal conversion circuit uses an analog-to-digital conversion chip. The data processing and transmission module conducts data interaction with external devices through a wireless communication module. The wireless communication module uses a Bluetooth 5.0 chip. Its function is as follows: The signal amplifier uses a low-noise operational amplifier chip, which can amplify the weak electrical signals from various sensors. Since the signals collected by the sensors are usually relatively weak and not convenient for subsequent processing and analysis, amplification by the low-noise operational amplifier chip can not only effectively improve the signal strength but also control the introduced noise at a low level, ensuring the quality and accuracy of the signal and laying a foundation for subsequent precise data processing. The signal conversion circuit uses an analog-to-digital conversion chip, and its function is to convert the amplified analog signal into a digital signal. The wireless communication module uses a Bluetooth 5.0 chip to achieve data interaction between the data processing and transmission module and external devices. The interaction module enables the user to interact with the device. It can combine the display screen 11 and other input and output devices to provide an intuitive operation interface for the user.

[0032] Embodiment 3, on the basis of Embodiment 1 and Embodiment 2, The upper arm micro pressure sensor in the circumferential elastic adjustment band 12, the angle sensor in the elbow guard plate 2, and the lower arm micro pressure sensor in the elastic magic tape 33 are all electrically connected to the processor inside the upper arm main body 1. Their functions are as follows: The data of all these sensors are uniformly transmitted to the processor inside the upper arm main body 1, and the processor, relying on its powerful computing ability, integrates and analyzes the multi-source data.

[0033] Working principle of the present invention: The peripheral electromyography sensor 422 is installed on the flexible silicone patch 42. The patch 42 is fixed to the external wiring 4 through the magnetic seat female seat 41 and the magnetic seat male seat 421 and can be pasted on the part to be detected to collect the muscle electrical activity signal. At the same time, in the contact terminal 1614 on the rear panel 16 of the upper arm main body 1, upper arm electromyography sensors are respectively arranged, and in the lower arm main body 3, lower arm electromyography sensors are arranged. They can collect the electrical activity signals of the upper arm and lower arm muscles, and these signals reflect the contraction and relaxation states of the muscles. The upper arm near-infrared spectroscopy sensor and the lower arm near-infrared spectroscopy sensor are respectively arranged in the contact terminal 1614 on the rear panel 16 of the upper arm main body 1 and in the lower arm main body 3. By detecting the absorption and scattering of near-infrared light by tissues, the blood oxygen content data of the upper arm and lower arm muscles are obtained, which are used to evaluate the metabolic state and fatigue degree of the muscles. The upper arm micro pressure sensor integrated in the circumferential elastic adjustment band 12 monitors the pressure on the upper arm in real time, reflecting the muscle force and wearing comfort; the lower arm micro pressure sensor integrated in the elastic magic tape 33 monitors the pressure on the lower arm to assist in analyzing the working state of the lower arm muscles. The angle sensor integrated in the elbow guard plate 2 measures the bending angle of the elbow joint in real time, helping to judge the standardization of the movement action and evaluate the recovery of the elbow joint in medical rehabilitation. All the analog signals collected by the sensors are transmitted to the processor inside the upper arm main body 1 through the contact terminal 1614 and related circuits. The data processing and transmission module set by the processor starts to work. Among them, the signal amplifier uses a low-noise operational amplifier chip to amplify the weak sensor signals, improve the signal strength and control the noise. Subsequently, the signal conversion circuit uses an analog-to-digital conversion chip to convert the amplified analog signal into a digital signal for subsequent operations, filtering, feature extraction, etc. by the processor, so as to obtain useful information such as muscle fatigue degree, movement mode, joint state, etc. The mechanical data memory 121 is used to store the data collected by the sensors and the results processed by the processor, and is powered by a built-in rechargeable lithium polymer battery. And it is provided with a power terminal line 1211 and a data terminal line 1212 for convenient data reading and transmission. When the processor determines muscle fatigue, abnormal training or other preset conditions according to the sensor data, it sends a signal to the tactile feedback controller of the tactile feedback system in the mechanical data memory 121. After the controller analyzes the signal, it issues an instruction to the tactile feedback actuator, and the piezoelectric ceramic sheet generates mechanical deformation to give the user tactile feedback to remind to adjust the training state. The data processing and transmission module performs data interaction with external devices through the wireless communication module. The user can view detailed data charts and analysis reports on the external device, and can also set the working mode, parameters, etc. of the device through the external device to achieve remote control and personalized settings.
