Description

Technical Field

[0001] This invention relates to the field of sports and health technology, and specifically to a control method and control system for a portable detection component based on multiple sensors. Background Technology

[0002] With the development of medical technology and the improvement of people's living standards, more and more people are paying attention to their health, especially the monitoring of parameters such as pulse, blood pressure, and body temperature. In order to monitor body data in real time, such as data during exercise, monitoring devices need to be worn by users. Therefore, various portable monitoring components have emerged, such as wristbands and ankle bracelets.

[0003] In adolescent height, body shape, and attention management, exercise is a crucial intervention method. However, existing fitness trackers and similar devices lack visualization and measurable standards, making it difficult for people to reasonably monitor their exercise, resulting in poor exercise effects. This is especially true for goal-oriented exercises with very specific objectives, such as weight management, height management, and attention management, where visualization and measurability of exercise intensity are essential.

[0004] While existing wristbands and ankle bracelets can detect the body's status in real time and record some basic exercise parameters, such as movement trajectory and pace, they cannot achieve precise quantification of exercise.

[0005] Therefore, there is an urgent need for a control method and control system based on a portable detection component with multiple sensors to solve at least one of the above problems. Summary of the Invention

[0070] To enable those skilled in the art to utilize the content of this invention, the following exemplary embodiments may be provided in conjunction with specific application scenarios, specific systems, device and component parameters, and specific connection methods. However, these embodiments are merely examples for those skilled in the art, and the general principles defined herein can be applied to other embodiments and application scenarios without departing from the spirit and scope of this invention.

[0071] like Figure 20-21As shown, this invention also provides a control method and control system for a portable detection component based on multiple sensors, including a height-increasing training mode, a weight management mode, and a focus-enhancing mode; users can select and enter the corresponding mode through a human-computer interaction interface; in this invention, users can select and enter the corresponding mode through an interactive interface on a display screen. The detection component includes: a position sensor, a height sensor, a motion sensor, and a heart rate sensor. The position sensor can be a GPS, the height sensor can be a barometer, and the motion sensor can be a nine-axis motion sensor. The portable detection component based on multiple sensors in this invention is also referred to as a portable detection component.

[0072] like Figure 20-21 As shown, the height-increasing training mode includes the following steps: obtaining basic user information, including age, height, weight, gender, BMI, etc., which are input by the user into the detection component.

[0073] Initial positioning is detected, including location and altitude. For example, the detection component of this invention incorporates a GPS and a barometer, which provide the user's precise location information. Before use, the barometer needs to be calibrated. A common calibration method is as follows: the detection component requires a known altitude reference value (e.g., manually entered current altitude, or automatically obtained via GPS), and the barometer calibrates the measured pressure value based on the standard atmospheric pressure corresponding to the current altitude. Optionally, this invention combines GPS and barometer data, using GPS to correct the atmospheric pressure reference and the barometer to provide smoother real-time altitude changes. Current location information is obtained via GPS, and the barometer is calibrated based on the standard atmospheric pressure at the current location. After the above calibration, a barometer such as the BOSCH BMP390 used in high-end smartwatches can detect altitude changes at the centimeter level.

[0074] The system retrieves the sports activity selected by the user. Users can select the corresponding sports activity through the interactive interface, such as rope skipping, jump, high jump, or other activities.

[0075] Obtain the user's exercise intensity; provide corresponding prompts based on the exercise intensity; the formula for calculating exercise intensity is: Where P is the exercise intensity, weight is the user's weight, g is the acceleration due to gravity, height is the average height of the exercise (e.g., the average height of the jump when skipping rope), number of jumps is the number of jumps, and T is the exercise time.

[0076] The state of exercise is determined based on the intensity value. If the exercise intensity is less than a first threshold, it is considered ineffective exercise; if it is greater than a second threshold, it is considered excessive exercise; and if it is between the first and second thresholds, it is considered effective exercise. In this invention, for example, for adolescents, ineffective exercise (below 900 Nm per minute), effective exercise (between 900 and 1500 Nm per minute), and excessive exercise (above 1500 Nm per minute) are defined as follows:

[0077] The lactate threshold time is defined as the effective exercise time after the cumulative effective and excessive exercise time reaches 10 minutes.

[0078] This invention acquires information on the user's left-right balance, posture symmetry, and number of jumps. For example, this invention uses a nine-axis sensor to acquire the user's posture information. The nine-axis sensor includes a three-axis accelerometer, a three-axis gyroscope, and a three-axis magnetometer. The nine-axis sensor reads data in real time, including acceleration, angular velocity, and magnetic force data. Jump count detection: During rope skipping, each jump generates a noticeable impact, which can be detected by the periodic changes in the vertical direction measured by the accelerometer. For example, the peak value of the acceleration is used to count. Left-right balance: By analyzing the accelerometer and gyroscope data, the shift in the body's center of gravity can be determined. For example, during rope skipping, changes in acceleration in the left-right direction can reflect balance. If the acceleration deviation in the left-right direction consistently leans to one side, it indicates imbalance. Posture symmetry: The symmetry of body rotation and the coordination of the accelerometer in the left-right and forward-backward directions can be analyzed using gyroscope data. For example, if the left and right arm swings are symmetrical, the angular velocity and acceleration in the left-right direction should have good symmetry.

[0079] Measurement of jump rope height: The height of the jump rope is detected by a barometer. Before jumping, the user keeps their wrist still for 1-2 seconds. The sensor collects the average air pressure during this period as the baseline air pressure, and the height at this time is recorded as h0. High-frequency sampling: Set the barometer sampling frequency to a preset frequency, such as 50~100Hz, and collect the wrist pressure value P(t) in real time during the rope skipping process.

[0080] Noise filtering: Arm movements during rope skipping generate sensor vibration noise. A first-order low-pass filter is used to smooth the data: P 滤波 (t) = a·P(t)+(1-a)·P 滤波 (t-1), where t is time, P(t) represents the current detected air pressure value, P 滤波 (t) represents the corrected air pressure value, P 滤波 (t-1) is the corrected air pressure value from the previous measurement, and a is the filter coefficient, which is 0.3-0.5.

[0081] Calculate the current altitude h based on the corrected air pressure value.

[0082] According to an exemplary embodiment of the present invention: combining data from a nine-axis sensor, the take-off-landing motion cycle of the jump rope is identified (the peak acceleration corresponds to the take-off, and the trough corresponds to the landing); within each motion cycle, the maximum height hmax is extracted, which is the effective height of the jump rope. The user's average power is obtained by dividing the work done by the user against gravity by the time. For example, in rope skipping, the average power is: .

[0083] The display screen shows the sport, timing, exercise time, average power, and the result of determining whether the exercise is effective or ineffective in real time.

[0084] According to an exemplary embodiment of the present invention, such as Figure 20-21 As shown, the weight management model includes the following steps: Obtain the user's basic information, including age, height, weight, gender, BMI, etc., which is input by the user into the detection component.

[0085] Recommended sports activities based on user information; the recommended sports activities include: HIIT, running, strength training, rope skipping, cycling or others.

[0086] Receive the item selected by the user and execute its start command.

[0087] The system detects initial positioning and the user's initial heart rate. The detection component of this invention includes a heart rate sensor; exemplaryly, the heart rate sensor and a pulse oximeter sensor are arranged side-by-side and connected to the motherboard. An exemplary heart rate sensor can be a sensor commonly found on wristbands, such as the MAX30105.

[0088] During exercise, the exercise time, average heart rate, and training load are recorded. Heart rate zones are determined: maximum heart rate is calculated by subtracting age from 220. Based on the user's maximum heart rate, exercise is divided into multiple zones, including the active recovery zone, aerobic endurance zone, aerobic power zone, lactate threshold zone, and anaerobic power zone. The active recovery zone is 50%-60% of maximum heart rate, the aerobic endurance zone is 60%-70%, the aerobic power zone is 70%-80%, the lactate threshold zone is 80%-90%, and the anaerobic power zone is 90%-100%. Heart rate data is monitored, and exercise time is calculated for each of the above zones.

[0089] Calculate the duration percentage of each interval: collect heart rate in real time and count the duration of each intensity interval during exercise.

[0090] Training load calculation: Weighted load calculation: Assign weights to different intervals (e.g., interval 1 weight 1, interval 5 weight 5), the higher the heart rate, the higher the weight assigned.

[0091] Total load = Σ (interval duration × interval weight).

[0092] Calculate calorie expenditure: Calorie expenditure = Basal metabolic rate (BMR) + Extra calories burned through exercise; BMR is calculated using the following empirical formulas: Various empirical formulas exist for calculating BMR; for example, the present invention may use the following empirical formula: Male BMR = 10 × weight (kg) + 6.25 × height (cm) - 5 × age (years) + 5; Female BMR = 10 × weight (kg) + 6.25 × height (cm) - 5 × age (years) - 161 Extra energy expenditure (EVE) can be calculated using the following formula: EVE = MET × Weight (kg) × Exercise Duration × K, where MET and K are constants assigned based on the heart rate range. For example, the MET and K values ​​are (3, 0.9), (4, 1), (5, 1.3), (6, 1.5), and (8, 1.8) for the active recovery zone, aerobic endurance zone, aerobic power zone, lactate threshold zone, and anaerobic power zone, respectively. That is, in the active recovery zone, MET is 3 and K is 0.9, and so on. It displays information such as the type of exercise, exercise time, maximum heart rate, and calorie consumption to users.

[0093] Save the exercise data when the exercise ends.

[0094] According to an exemplary embodiment of the present invention, such as Figure 20-21 As shown, the focus enhancement mode includes the following steps: Initial positioning is detected, which includes position and altitude.

[0095] Obtain the sport selected by the user; the sport may include rope skipping or others.

[0096] The system retrieves the user's exercise program and displays information on the screen, including exercise program, exercise time, average power, and number of repetitions.

[0097] According to an exemplary embodiment of the present invention, the method further includes the following steps: periodically reminding the user to update user information, including height, weight, and age; adjusting the recommended exercise programs and times based on changes in user information. For example, if the change in height does not meet expectations within a certain period, the recommended exercise time and intensity are increased.

[0098] For example, the method also includes the following steps: uploading the body and exercise data of a certain number of users to a server; the server analyzes the data and adjusts the recommended exercise programs and times based on the analysis. Identification information is concealed during data upload. For example, if user A's expected height growth is good, their exercise duration and intensity are used as recommendation data and recommended to user B, whose age, height, and weight are not significantly different from user A's.

[0099] This invention enables faster and more accurate identification of a user's exercise status by setting multiple training modes and allowing users to select these modes and pre-set exercise programs. This allows for precise acquisition of the user's exercise information. Simultaneously, through accurate calculation of exercise intensity, the current exercise status can be accurately provided to the user. During exercise, the combination of motion sensors and a barometer can accurately determine the exercise cycle and altitude. Furthermore, by detecting heart rate and classifying the exercise based on the user's maximum heart rate, exercise consumption can be calculated relatively accurately, providing suggestions for body control. Finally, by uploading a certain number of users' body data to a server and analyzing the information, more rational suggestions can be made.

[0102] For example, such as Figure 1-4 As shown, the main body 10 is generally formed into a flat structure. Its top surface 12 and bottom surface 11 have outer peripheral surfaces including curved segments on both sides and a straight segment in the middle. Its side surfaces 13 are also formed into curved surfaces to make it more aesthetically pleasing overall.

Figure 1-9 As shown, a transparent area 14 is also provided on the bottom surface 11, and the transparent area 14 protrudes from the bottom surface 11. The charging base 30 has a recessed area 31 corresponding to the transparent area 14.

[0103] According to an exemplary embodiment of the present invention: Figure 1-4 As shown, a first snap-fit ​​portion is formed on the side 13. Figure 7-9 As shown, it also includes at least one replaceable accessory, which includes a first accessory 20 and / or a second accessory 40. The first accessory 20 includes a second snap-fit ​​portion, which, through its engagement with the first snap-fit ​​portion, allows the first accessory 20 to be detachably attached to the body 10. The second accessory 40 includes a third snap-fit ​​portion, which, through its engagement with the first snap-fit ​​portion, allows the second accessory 40 to be detachably attached to the body 10.

[0104] For example, the first snap-fit ​​portion includes a first snap-fit ​​groove 131, and the second snap-fit ​​portion includes a first snap-fit ​​protrusion, the first snap-fit ​​protrusion being detachably snapped into the first snap-fit ​​groove 131. The first snap-fit ​​portion also includes a second snap-fit ​​groove 132, and the second snap-fit ​​portion includes a second snap-fit ​​protrusion 222, the second snap-fit ​​protrusion 222 being detachably fixed in the second snap-fit ​​groove 132.

[0105] like Figure 7-9 As shown, the first accessory 20 includes a straight portion 23, a first covering portion 21, and a second covering portion 22. When the first accessory 20 covers the main body 10, the first covering portion 21 and the second covering portion 22 cover the side surface 13, and a first gap is formed between the straight portion 23 and the bottom surface 11. Through the first gap, it can be fixed to the human body by means of a strap, rope, or the like.

[0106] like Figure 7-9 As shown, it also includes a first spring tab 24, with a notch formed in the first covering portion 21, and the first spring tab 24 located within the notch; a first snap-fit ​​protrusion is located at the end of the first spring tab 24. The first snap-fit ​​protrusion also includes a first inner protrusion 241 that mates with the first snap-fit ​​groove 131, and a first outer protrusion 242 that facilitates pulling by hand. With the provision of the first spring tab 24, the first accessory 20 can be easily detached from the main body 10.

[0107] like Figure 7-9 As shown, weight-reducing holes 221 are also formed on the second covering portion 22. The weight-reducing holes 221 enhance the aesthetics and reduce the weight of the first accessory 20. This is particularly important when carrying the aforementioned portable component for activities such as running.

[0108] like Figure 1-9As shown, preferably, a knob 133 and a button 134 are also formed on the side 13 of the main body. The knob 133 and the button 134 are disposed on the operating seat, which protrudes from the side 13 and has grooves for mounting the knob 133 and the button 134, respectively. Preferably, the operating seat is also provided with a reset hole 135.

[0109] like Figure 1-9 As shown, at least one support bar 231 is also provided on the straight portion 23. Exemplarily, there are two support bars 231, which are approximately V-shaped. By providing the support bars 231, when the first accessory 20 is placed on the main body 10, the two support bars 231 abut against the bottom surface 11, thereby forming a gap and providing stable support between the first accessory 20 and the main body 10.

[0110] like Figure 10-12 As shown, the portable detection component also includes a second accessory 40, which includes a third latching part. Through the cooperation of the third latching part and the first latching part, the second accessory 40 can be detachably covered on the main body 10.

A third snap-fit ​​protrusion is formed on the second spring piece 43. A third spring piece 44 is formed inside the third notch. A fourth snap-fit ​​protrusion is formed on the third spring piece 44.

[0113] The third snap-fit ​​protrusion includes a second inner protrusion 431 that mates with the first snap-fit ​​groove 131 and a second outer protrusion 432 that facilitates outward pulling. The fourth snap-fit ​​protrusion includes a third inner protrusion 441 that mates with the second snap-fit ​​groove 132 and a third outer protrusion 442 that facilitates outward pulling.

[0114] like Figure 10-12 As shown, a first hole is formed on the first perforation portion 41, and a second hole is formed on the second perforation portion 42. In use, the watch strap can pass through the first hole and the second hole and be worn on the arm.

[0115] like Figure 13-15As shown, the main body 10 of the present invention can cooperate with the charging base 30 to complete charging. Due to the separate design of the main body 10 and the charging base 30, the main body 10 can have a smaller structure and is easy to carry. The main body 10 can cooperate with the first accessory 20, and when cooperated with the first accessory 20, it can be fixed to something such as a shoe. The main body 10 can cooperate with the second accessory 40, and when cooperated with the second accessory 40, the main body 10 can be fixed to something such as a watch strap, and thus worn on the arm. Through the provision of replaceable accessories, the present invention has a compact and multi-purpose structure.

[0116] like Figure 13-15 As shown, the first accessory 20 adopts a support structure, which ensures sufficient clearance and structural strength when the first accessory 20 is engaged with the main body 10. The first accessory 20 and the second accessory 40 adopt a spring-loaded design and utilize an outward protrusion structure design to facilitate the disassembly of the main body 10 from the first accessory 20 and the second accessory 40.

[0117] According to an exemplary embodiment of the present invention, such as Figure 16-19 The diagram shows a portable detection component, comprising a main body, which includes a housing. The housing includes a top surface 12, a bottom surface 11, and a side surface 13. A detection device is located inside the housing, used to detect at least one physiological parameter and at least one motion parameter of a user. The housing also contains a circuit board 50, a communication board, a battery 70, a display screen 80, and a keypad 90. A 4G antenna is mounted on the communication board. A GPS positioning module and a Bluetooth module, including a Bluetooth antenna, are also mounted on the main body.

[0118] The mainboard 50 is electrically connected to the detection device, communication board, battery 70, display screen 80, and keypad 90. The mainboard 50 integrates a power module, which is electrically connected to the battery 70, as well as to the detection device, communication board, display screen 80, and keypad 90. Simultaneously, the detection device, keypad 90, communication board, and display screen 80 are all connected to the mainboard 50 via signal transmission.

[0119] like Figure 16-19 As shown: The motherboard 50 is provided with a first charging connector, which protrudes from the motherboard 50. The bottom surface 11 is provided with a first groove that mates with the first charging connector. The bottom surface 11 is provided with a transparent area 14, which protrudes from the bottom surface 11. The pulse oximeter sensor detects the user's blood oxygen status through the transparent area 14.

[0120] like Figure 16-19 As shown: The motherboard 50 is fixed inside the housing, preferably on the transparent area 14 of the bottom surface 11. The motherboard 50 coordinates and connects the detection device, communication board, battery 70, display screen 80, and keypad 90 to ensure their coordinated operation.

[0121] The communication board of this invention is preferably a 4G board 60, which can be a Quectel EC25-EF. The motherboard 50 includes a main control chip and a PCB circuit board. The main control chip is, for example, an STM32 microcontroller. The motherboard 50 integrates a power module; for example, an EBITE ECB30-P4T13IA5ME8G-I motherboard 50 with an integrated power module is used. The display screen 80 can be a Solomon Systech ILI9341 LCD display screen 80.

[0122] For example, it also includes a GPS device, which is electrically connected to the motherboard 50. The power module is electrically connected to the GPS device, and the GPS device is also signal-connected to the motherboard 50. The GPS device can be the ATGM336H-5N31 from Zhongke Microelectronics.

[0123] The detection device includes a pulse oximeter sensor and a motion sensor. The preferred motion sensor is a nine-axis sensor, which is an integrated motion and attitude detection module combining a three-axis accelerometer, a three-axis gyroscope, and a three-axis magnetometer (electronic compass). It can output real-time data on the object's linear acceleration, angular velocity, and magnetic field direction, accurately calculating the object's three-dimensional attitude angles. The MPU6050 sensor can also be used, primarily responsible for step counting and fall detection.

[0124] The blood oxygen sensor used is MAX301021, which uses two different wavelength light sources—red light and infrared light—for detection.

[0125] like Figure 16-19 As shown: The keypad 90 of this invention is a keypad 90 with an encoder 93. Keypads 90 with encoders 93 (including rotary encoder 93 + key matrix) are widely used in industrial control. This invention uses the MT-KEP-01 scanning keypad 90 from Maichong Technology. The keypad 90 includes an encoder 93, a first pressure sensor 91, and a second pressure sensor 92. The housing is provided with a knob and a button that cooperate with the keypad 90. The button cooperates with the first pressure sensor 91. The knob is rotatably connected to the encoder 93 interface, and the encoder 93 is used to receive the rotation information of the knob.

[0126] The keypad 90 is fixed to the inner side of the side panel, and an operating seat is formed on the outer side of the side panel. The operating seat has a second groove for mounting a knob and a third groove for mounting a button. The operating seat protrudes from the side panel, and the tops of the buttons and knobs are approximately flush with the top of the operating seat. The keypad 90 also has a second pressure sensor, and the operating seat has an operating hole corresponding to the second pressure sensor.

[0127] The present invention preferably also includes a barometer, which can be used to obtain altitude by detecting air pressure, assisting in the calculation of slope and vertical amplitude, and expanding the application range, such as in outdoor mountaineering and other scenarios. OMRON's 2SMPB-02B / 02E is an option.

[0128] like Figure 16-19 As shown: Inside the housing, from the bottom surface 11 to the top surface 12, the main board 50, the communication board, and the battery 70 are arranged sequentially. The top surface 12 has a fourth slot for mounting the display screen 80.

[0129] like Figure 16-19 As shown: The side interior is provided with a first bracket 94 and a second bracket 95. The first bracket 94 is provided with a first groove 941 and the second bracket 95 is provided with a second groove 951. The button panel 90 is provided with a third groove 961 and a fourth groove 962. The third groove 961 can be engaged with the first groove 941 and the fourth groove 962 can be engaged with the second groove 951.

[0130] Through the design of the circuit board configuration and its placement, it possesses both motion detection and body detection functions, while maintaining a compact size. The transparent area 14 allows the pulse oximeter to detect the body's condition through this area. The button panel 90 is positioned on the side, minimizing its internal space occupation and facilitating convenient and aesthetically pleasing operation in conjunction with the control unit. By integrating the power module onto the mainboard 50 and utilizing the opening on the bottom surface 11, the first charging module protrudes outwards, facilitating charging while further reducing its internal space occupation, resulting in a more compact internal circuit board structure.

[0131] According to an exemplary embodiment of the present invention, such as Figure 22-26 As shown, the portable detection assembly also includes a third accessory, which includes an outer cover 26 and an elastic element 27 fixed to the outer cover. The outer cover has a first mating hole 261 and a second mating hole 262. The first mating hole 261 allows the operating seat on the main body 10 to pass through, so as not to affect the operation of the knob 133 and button 134 on the operating seat. The second mating hole 262 is used to place the transparent area 14.

[0132] The outer cover 26 has a certain degree of elasticity, such as Figure 22-26 As shown, the side cover of the outer cover 26 is designed with a tapered opening, making the size of its entrance smaller than its center size, thus preventing the main body 10 from falling out when placed inside the outer cover 26. The outer cover 26 is designed to be flexible, allowing the main body 10 to be easily placed inside the outer cover 26.

[0133] The elastic element 27 on the outer cover is bent, so that its elasticity can be used to easily fix it to other objects.

[0134] The third accessory design of this invention can further expand the application scenarios of this invention, making it easy to fix it to a belt, for example, by means of the elastic element 27.

[0135] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that variations and combinations of elements may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
