Description

Technical Field

[0001] The present invention relates to the technical field of sports equipment, and in particular to a treadmill and a running status monitoring method, device, and storage medium. Background Art

[0002] Treadmills are becoming more and more popular and loved by the public because of their freedom and convenience in use without being restricted by time and place.

[0003] When exercising on a treadmill, if a user's foot placement is off-center, it can be dangerous. Therefore, it's necessary to design a safety protection system and method to monitor running status, determine the user's foot placement, and provide real-time alerts. Traditional models mostly use visual or infrared methods to make this determination to ensure user safety. However, visual and infrared design solutions are not only complex and costly to implement, but also highly susceptible to environmental factors. For example, visual methods are easily affected by lighting, position, and other factors, while infrared methods lack stability. Vibrations generated during running can cause infrared detection to deviate, affecting detection readiness. Summary of the Invention

It should also be understood that terms such as those defined in common dictionaries should be understood to have meanings consistent with those in the context of the prior art and, unless specifically defined, will not be interpreted in an idealized or overly formal sense.

[0046] Figure 1The flowchart of the running state monitoring method according to one embodiment of the present invention is schematically shown. Figure 1 The running status monitoring method proposed in the embodiment of the present invention specifically includes steps S11 to S16, as shown below:

[0047] S11. When the treadmill enters the running state, the running pressure data of the pressure sensors located at the four corners of the treadmill running board are recorded in real time.

[0048] Furthermore, four pressure sensors are provided, mounted on either side of the running deck. There are two pressure sensors, one in front and one in the back, on each side. Specifically, by placing four pressure sensors at the four corners of the treadmill deck, sensor signals, i.e., running pressure data, are collected in real time when the treadmill enters the running state.

[0049] S12, detecting peak positions and trough positions in the running pressure data from the pressure sensors at various positions;

[0050] Furthermore, in an embodiment of the present invention, after detecting the peak and trough positions in the running pressure data from the pressure sensors at various locations, the user's running cadence can be determined based on the peak or trough positions in the running pressure data within a first preset time period; and based on the running cadence, whether the user's cadence is chaotic, thereby creating a danger, can be determined. Specifically, when the amplitude of the change in the user's running cadence within the first preset time period is greater than a preset change threshold, the user's cadence is determined to be chaotic, and a cadence alarm is issued to avoid danger. The value of the second preset time period can be set according to actual application requirements and is not specifically limited by the present invention.

[0051] Specifically, when the user is running, the peaks or troughs in the running pressure data of the pressure sensors at various positions are detected. The peak value is the time when the user lands his foot, and the trough value is the time when the user lifts his foot. By recording the peaks or troughs over a period of time, the cadence can be calculated and monitored. If the short-term change exceeds a threshold, such as sometimes fast and sometimes slow, etc., it means that the user's cadence is chaotic and may not be able to keep up, then an early warning will be issued to avoid danger.

[0052] S13. Calculate the foot landing position of the current running action based on the running pressure data at the time point corresponding to the peak position, and calculate the real-time position of the user on the treadmill after landing based on the foot landing position of the current running action and the current belt speed of the treadmill.

[0053] In this embodiment, a preset first calculation model is specifically used to calculate the landing position P of the current running action. The first calculation model is as follows: P = a*w1*P1+b*w2*P2+c*w3*P3+d*w4*P4; wherein P1, P2, P3, and P4 are the two-dimensional position vectors of the four pressure sensors located at the four corners of the treadmill running deck, respectively; w1, w2, w3, and w4 are the running pressure data of the four pressure sensors corresponding to the peak position time point closest to the current time; and a, b, c, and d are preset adjustment parameters.

[0054] The bias adjustment parameters a, b, c, and d are preset fixed values. In an optional embodiment, the bias adjustment parameters a, b, c, and d can take the values ​​of 1, 1, 1, and 1, indicating that all four sensors are unbiased. It is understood that the specific values ​​of the bias adjustment parameters a, b, c, and d can be obtained through experimentation. For example, a tire impact tester of different weights can be used as an experimental device, and pressure can be applied to the running board at corresponding different positions. Sensor data from the pressure sensors during each experimental process can then be collected using computational methods such as machine learning to fit the optimal values ​​of a, b, c, and d.

[0055] Specifically, the peak is the time of the footfall. Therefore, by obtaining the peak in the running pressure data from the pressure sensors at various locations, the current footfall position can be calculated using the averaging algorithm of the first calculation model. During running, the footfall is almost dragged along by the treadmill after landing. Therefore, using the footfall position, combined with the current speed, the user's real-time position on the treadmill after landing can be calculated. The real-time position is the position of the foot on the treadmill at any given time. The footfall position refers to the position at the moment of landing on the treadmill. Because the footfall is dragged along after landing on the treadmill, the footfall position is different from the real-time position.

[0056] S14. Calculate the foot lift position of the user's next running action based on the time points corresponding to the peak position and the trough position, the real-time position, and the current belt speed of the treadmill.

[0057] In this embodiment, the foot lift position of the user's next running action is calculated based on the time points corresponding to the peak position and the trough position, the real-time position, and the current belt speed of the treadmill. The specific implementation steps include: using the time point corresponding to the trough position closest to the current time as the foot lift time, and using the time point corresponding to the peak position closest to the current time as the foot landing time; and using a preset second calculation model to calculate the coordinate value of the foot lift position of the user's next running action. The second calculation model is as follows:

[0058] The y-coordinate value of the foot-lifting position = the y-coordinate value of the real-time position - the current running belt speed * (foot-lifting time - foot-landing time); the x-coordinate value of the foot-lifting position = the x-coordinate value of the real-time position, where the running belt movement direction is set as the y-axis direction, and the direction perpendicular to the running belt movement direction on the same horizontal plane is the x-axis direction.

[0059] Specifically, the foot lift time can be determined by determining the occurrence of a trough in the running pressure data from the pressure sensors at various locations. A trough indicates when the pressure sensor's value is at its minimum, corresponding to the time when no one is stepping on it during the running process. For example, let's define the y-axis as the running belt's direction of motion and the x-axis as the perpendicular to the running belt's direction of motion. Then, for the running belt's direction of motion: the y-coordinate value of the foot lift position = the y-coordinate value of the real-time position - the current running belt speed * (foot lift time - foot landing time). For the perpendicular direction: the x-coordinate value of the foot lift position = the x-coordinate value of the real-time position.

[0060] S15: Determine whether the real-time position and / or the foot-lifting position is in a preset dangerous position area on the treadmill running board.

[0061] S16: When the real-time position and / or the foot-lifting position is in a preset dangerous position area on the treadmill running board, an out-of-bounds alarm prompt is issued.

[0062] In an embodiment of the present invention, a dangerous position area is preset on the treadmill running board. During the running process, when the real-time position of the user's foot on the treadmill after landing and / or the position of the user's foot lifting in the next running action is in the preset dangerous position area, a real-time warning will be issued. For example, if the landing position is too far to the left or right, or the foot lifting position is too far back, an out-of-bounds alarm will be issued.

[0063] The running status monitoring method provided by the embodiment of the present invention analyzes the running pressure data detected by the pressure sensors located at the four corners of the treadmill running board, and calculates in real time the real-time position of the user's foot on the treadmill after landing and the position of the user's foot lift in the next running action, thereby determining whether the user has deviated from the running area and reminding the user in real time to prevent the user from running off or falling off the treadmill and causing danger, thereby improving the user experience.

[0064] Moreover, the present invention adopts four sensors to realize the running status monitoring of the treadmill, which is low-cost and easy to install. Through algorithm calculation, it can prompt a variety of situations and can more conveniently realize the safety monitoring effect during exercise.

[0065] It is understandable that in order to further improve the accuracy of running status monitoring, pressure sensors can be added to other positions of the treadmill running board, or multiple pressure sensors can be placed at the four corners of the treadmill running board to detect running pressure data. The technical solution of placing four pressure sensors at the four corners of the treadmill running board in the present invention is only used to explain the technical solution and does not provide specific limitations.

[0066] In an embodiment of the present invention, before recording the running pressure data of the pressure sensors located at the four corners of the treadmill deck in real time, sensor data collected by the pressure sensors located at the four corners of the treadmill deck is obtained, and whether the user has boarded the treadmill is monitored based on the sensor data; based on the sensor data collected by each pressure sensor when the user boards the treadmill, it is determined whether the treadmill currently has a hidden danger of being left in the air; if there is a hidden danger of being left in the air, an air suspension alarm is issued; otherwise, the working status of the treadmill is monitored, so that when the treadmill enters the running state, the operation of recording the running pressure data of the pressure sensors at each position in real time is executed.

[0067] In an embodiment of the present invention, before exercising, it is possible to monitor whether the user has boarded the treadmill based on the sensor data collected by the pressure sensor. When the user stands on the treadmill, it is determined whether the sensor data of the current pressure sensors have changed consistently. For example, if the values ​​of three pressure sensors increase and the value of one pressure sensor hardly increases, it can be determined that the corresponding position of the pressure sensor whose value does not increase is suspended in the air, and the treadmill is on an uneven ground, and there is a hidden danger of being suspended in the air. At this time, a suspension alarm prompt is issued to avoid danger to the user during exercise.

[0068] In an embodiment of the present invention, in order to ensure the accurate availability of data, initial sensor data collected by pressure sensors located at the four corners of the treadmill running board can also be obtained when the treadmill is in an unloaded state, and the pressure sensors can be calibrated based on the initial sensor data.

[0069] Specifically, when the treadmill is started, the sensor values ​​are recorded for a period of time in the unloaded state to perform sensor calibration and record the current values. Furthermore, sensor data may fluctuate or sometimes contain illegal values ​​due to electromagnetic interference, so a filtering algorithm can be used to ensure data consistency.

[0070] When the treadmill is unloaded, each pressure sensor is read. Using average filtering, the average value over a period of time is recorded as the initial sensor data for that pressure sensor. When each pressure sensor's data is read again, the difference between the read value and the initial sensor data is calculated to complete calibration. While theoretically, the results obtained when unloaded are all zero, in reality, they fluctuate around zero, requiring calibration for accurate data analysis.

[0071] In an embodiment of the present invention, the method further includes: recording running pressure data collected by pressure sensors located at the four corners of the treadmill deck using the time points corresponding to the peak positions as indexes to form a queue; analyzing the landing pressure of the left and right feet based on the positional relationship between the pressure sensors and the running pressure data collected by each pressure sensor; and providing an imbalance warning during exercise if the landing pressure of the left and right feet remains unbalanced within a second preset time period. The value of the second preset time period can be set according to actual application requirements and is not specifically limited by the present invention.

[0072] Specifically, the present invention can record sensor values ​​based on the landing time to form a queue. The left and right feet can be determined through the sensor position relationship, and the landing pressure can be calculated through the left and right foot values. If the two feet always land unbalanced for a period of time, an early warning prompt will be issued during exercise.

[0073] Furthermore, based on the position information of the pressure sensor itself, the sensor peak value queue is recorded, and it can be calculated to distinguish whether the current landing foot is the left foot or the right foot. In an optional embodiment, considering a queue formed by several consecutive landing points, for two consecutive landing points in the queue, if the sum of the sensor values ​​on the left side of the first landing point is greater than the sum of the sensor values ​​on the right side, and the sum of the sensor values ​​on the left side of the second landing point is less than the sum of the sensor values ​​on the right side, it can be judged that the first landing point is the left foot and the second landing point is the right foot. Assuming that when the landing point is the left foot, the four sensor values ​​are w1, w2, w3, and w4, and when the landing point is the right foot, the four sensor values ​​are u1, u2, u3, and u4, then it can be calculated that pr=(a*w1+b*w2+c*w3+d*w4) / (a*u1+b*u2+c*u3+d*u4) is the ratio of the landing pressure of the left and right feet, and a, b, c, and d are preset adjustment parameters. When the ratio of the landing pressure of the left and right feet is greater than or less than a preset threshold for a period of time, it can be determined that the ground pressure of the user's left and right feet is unbalanced, and an early warning prompt is given to the user.

[0074] The running status monitoring method provided by the embodiment of the present invention analyzes the running pressure data detected by the pressure sensors located at the four corners of the treadmill running board, calculates the user's foothold on the treadmill in real time, thereby determining whether the user has deviated from the running area, and giving a reminder in real time to avoid danger to the user. The reminder part mainly includes: whether the treadmill is in an uneven position, making the exercise dangerous; whether the user's stride frequency is chaotic, thus creating a danger; whether the user's foothold is too deviated, which may cause the user to run off the treadmill or fall off the treadmill, thus creating a danger; whether the user's left and right feet have inconsistent landing force, and the running posture is incorrect, thus causing some chronic injuries.

[0082] The alarm module 206 is used to issue an out-of-bounds alarm when the real-time position and / or the foot-lifting position is in a preset dangerous position area on the treadmill running board.
