The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are only one of the aspects of the invention as detailed in the appended claims. An example of a device.

1 is a schematic and logical block diagram of a sports health management platform, according to an exemplary embodiment. For example, the sports health management platform includes: a sports intelligent device and a mobile terminal, the sports intelligent device is worn on the user, acquires motion data of the user, and transmits the motion data to the mobile terminal through wireless communication.

A plurality of devices are embedded in the sports intelligence device to closely fit the human body, and the devices include: a main control unit and a first sensor unit.

The first sensor unit may be disposed in plurality, and is disposed in a position corresponding to the sports intelligent equipment and the human body. The main control unit is disposed at any position of the sports intelligent equipment, and is convenient for accessing the position of the main control unit, such as the front chest or the rear. The position of the back, etc. In this embodiment, the first sensor is disposed at four positions of the thigh, the lower leg, the upper arm, and the lower arm to facilitate capturing the motion parameters of the limb.

Referring to FIG. 2, in particular, the first sensor unit includes: a microcontroller, an inertial sensor module connected to the microcontroller, a storage module, a wireless transmission module, and a power module providing power, and the wireless transmission module is also connected to the main control unit. . The inertial sensor module acquires the attitude data and stores it in the storage module. The microcontroller retrieves the attitude data in the storage module and transmits it to the main control unit through the wireless transmission module, and then transmits the data to the mobile terminal through the main control unit.

In this embodiment, the microcontroller uses the STM32F411 chip to perform calculation processing on the obtained data. The inertial sensor module obtains the posture data of the user in motion, and then caches the posture data in the storage module. The microcontroller reads the attitude data in the storage module and transmits it to the main control unit through the Bluetooth transmission module, and the transmission module may also be an infrared module, a WiFi module, or the like.

In addition, the main control unit is set to one, and a wireless transmission device such as Bluetooth or infrared is disposed therein. The main control unit acquires the attitude data of the first sensor unit that is disposed at different positions, and the posture data is uniformly forwarded by the main control unit to the mobile terminal, thereby preventing the Bluetooth transmission module of the multiple sensor units from directly transmitting to the mobile terminal, thereby causing the connection. Disordered, unstable. Of course, in other embodiments, the main control unit is set to multiple, for example two or three. The plurality of main control units are set based on the number of sensor units being too large, and the posture data can be acquired in a sub-area and forwarded to the mobile terminal in a sub-sequence. For example, the main control unit A acquires the sensor unit of the arm, and the main control unit B acquires the sensor unit of the leg.

Further, the inertial sensor module includes a gyroscope, an accelerometer and a magnetometer, which may be three-axis, six-axis or nine-axis, while the gyroscope acquires angular motion data, the accelerometer acquires linear acceleration, and the magnetometer detects magnetic yaw. In this embodiment, the gyroscope and the accelerometer adopt the MPU6500 six-axis MEMS sensor chip, and the magnetometer adopts the AK8963 three-axis electronic compass chip. Of course, different types of chips can be selected according to the needs of monitoring accuracy.

In an embodiment, the sports intelligence device further includes a second sensor unit coupled to the main control unit. The second sensor unit is identical to the base module in the first sensor unit, that is, the adopted microcontroller, the inertial sensor module, the storage module, the wireless transmission module, and the power module are identical.

Referring to FIG. 3, specifically, the second sensor unit includes a microcontroller, an inertial sensor module connected to the microcontroller, a human health monitoring sensing module, a storage module, a wireless transmission module, and a power module for providing electrical energy; human health monitoring The sensing module obtains the health data and stores it in the storage module.

Similarly, the inertial sensor module acquires the attitude data and stores it in the storage module, and the microcontroller retrieves the attitude data in the storage module and transmits it to the main control unit through the wireless transmission module, and then transmits the data to the mobile terminal through the main control unit.

In this embodiment, the second sensor unit is disposed near the chest of the sports intelligent device, and the human health monitoring sensing module includes a heart rate sensor, a respiratory rate sensor, a blood pressure sensor, an EEG sensor, and a skin electric sensor. The user's heart rate, respiration rate and blood pressure are monitored on the chest, forehead, earlobe or finger.

Referring to FIG. 4, in an embodiment, the first sensor unit and/or the second sensor unit further includes an environmental monitoring sensor module and acquires environmental data. The environmental monitoring sensor module includes a VOC (volatile organic compounds) sensor, a temperature sensor, and an ultraviolet radiation sensor, which respectively obtain the VOC (volatile organic compounds) concentration, temperature, and ultraviolet radiation amount of the user's motion scene.

Referring to Figures 5-6, in an embodiment, the inertial sensor module in the first sensor unit and the second sensor unit further includes: a first-stage Kalman filter and a second-stage Kalman filter. The first-order Kalman filter uses an accelerometer to make observation corrections to the roll and pitch angles, and the second-stage Kalman filter uses a magnetometer to make observation corrections to the yaw angle.

Further, a detailed process of generating the attitude data, that is, the inertial sensor module in the first sensor unit and the second sensor unit, which processes the acquired posture data, is further described.

Before the user moves, the mobile terminal pre-displays a fixed action for initialization (for example, a "right" action), performs initialization, and acquires an initial quaternion. The user starts to move, and the data measured by the gyroscope, the accelerometer, and the magnetometer are respectively subjected to Kalman filter fusion. In this embodiment, a two-stage extended Kalman filter algorithm is used, which uses an accelerometer to make observation and correction of the roll angle and the pitch angle, and uses a magnetometer to make an observation correction of the yaw angle, and finally outputs a quaternion for posture update. The operation is used as the initial quaternion of the next action, and the quaternion is transmitted to the mobile terminal. The 3D restoration processing module of the mobile terminal performs three-dimensional image reconstruction on the received quaternary data. In the embodiment, the 3D restoration processing module is Unity3D, and then the 3D posture display module performs real-time human body gesture display on the reconstructed three-dimensional image.

Compared with the commonly used algorithm, the first-order extended Kalman filter fusion algorithm is used. The computational complexity is large. The two-stage extended Kalman filter algorithm used in this scheme performs a pose update calculation in the two-stage extended Kalman filter, which can reduce the number of operations. Shorten the calculation time and improve the efficiency of attitude calculation. At the same time, the scheme uses the quaternion instead of the traditional Euler angle as the system state quantity and attitude update, which can effectively avoid the moment of movement to the singularity and avoid the "deadlock".

The description will now be made in conjunction with specific embodiments. Any posture of the human body can be expressed by Euler angles, such as the arm horizontally straight forward, palm up, the initial definition is the heading angle of 0 degrees, the horizontal straightness is the pitch angle of 0 degrees, and the palm is the roll angle of 0. Degree, then (0,0,0) can represent the initial pose. In order to avoid the occurrence of singularities in Euler angles, the scheme uses quaternions, and the quaternions corresponding to Euler angles (0,0,0) are (1,0,0,0). At this time, Unity3D is used to build one. The human body model transmits (1,0,0,0) to the corresponding arm in the model. At this time, the arm will be horizontally straight forward and palm up, and the process will restore the human body posture. The key point of the human body posture reduction in this scheme is to obtain the quaternion of (1,0,0,0), which is the accurate quaternion measured according to the gyroscope, accelerometer and magnetometer in this scheme. Imaging is available through Unity3D processing.

Referring to FIG. 7, in an embodiment, the mobile terminal presets a human motion trajectory, compares the acquired posture data with a preset human motion trajectory, and obtains feedback information. Specifically, the user performs corresponding actions according to the preset human body motion posture, and when the action performed by the user is not standard, that is, the posture data and the preset acquired by the inertial sensor module in the sensor unit and the second sensor unit of the user action are preset. At the reference attitude data of the mobile terminal, a certain deviation value is set, and if the acquired posture data exceeds the deviation value, feedback information of the motion posture is issued. The mobile terminal feeds back information through voice, text or image mode, thereby guiding the user to adjust the motion movement. Of course, for the user to perform the correct action, it will also feedback the correct action information, encourage and guide the user to continue to exercise.

The mobile terminal presets the human body safety data, compares the acquired health data with the preset human body safety data, and obtains human health warning data. Specifically, the mobile terminal pre-sets data during the movement of the human body, such as setting of data values such as heart rate, respiratory rate, and blood pressure, and the health data obtained by the human health monitoring sensor module of the second sensor unit during the movement of the person. Compared with the preset health data, if the preset deviation range is exceeded, a human health warning is issued to guide the user to adjust the rhythm and intensity of the exercise. The human health warning can be displayed in a voice, text or image mode. Further, when the obtained health data far exceeds the deviation range, for example, the health data value that is dangerous to life is reached, the mobile terminal sends an early warning call or short message to the hospital, the neighbor or its family to realize the remote warning function.

The mobile terminal presets the environmental safety data, compares and analyzes the acquired environmental data with the preset environmental safety data, and obtains the motion environment warning data. Specifically, the mobile terminal presets corresponding environmental safety data according to an external environment that is most suitable for the user's motion, and sets a deviation range. When the environmental data acquired by the environmental monitoring sensor module of the first sensor unit and/or the second sensor unit is compared with the preset environmental safety data, if the deviation range of the environmental safety data is exceeded, the motion environment warning data is issued to prompt the user. The VOC concentration, temperature, and ultraviolet radiation of the external environment do not meet the environmental standards of exercise, guiding the user to adjust the exercise plan, or even give up the exercise.

Based on the above feedback information, human health warning data and sports environment warning data, real-time feedback can be provided. The mobile terminal can adjust or set the user's exercise plan in real time to comprehensively guide the user to exercise healthily and effectively.
