Fig. 1 schematically shows a flowchart of a running state monitoring method according to an embodiment of the present invention. Referring to fig. 1, the running state monitoring method provided by the embodiment of the invention specifically includes steps S11 to S16, as follows:
S11, when the running machine enters a running state, running pressure data of pressure sensors positioned at four corners of a running plate of the running machine are recorded in real time.
Further, the pressure sensors are four, and the pressure sensors are respectively arranged on two sides of the running board. Two pressure sensors are arranged on the two sides. Specifically, 4 pressure sensors are placed at four corners of a running plate of the running machine, so that sensor signals, namely running pressure data, are collected in real time when the running machine enters a running state.
S12, detecting the peak position and the trough position in running pressure data of the pressure sensors at all positions;
further, in the embodiment of the invention, after the peak position and the trough position in the running pressure data of the pressure sensor at each position are detected, the running frequency of the user can be determined according to the peak position or the trough position in the running pressure data within the first preset time period, and whether the running frequency of the user is disordered or not is determined according to the running frequency, so that danger is generated. Specifically, when the variation amplitude of the running frequency of the user within the first preset duration is greater than a preset variation threshold, the user is judged to be confused in the running frequency, and the running frequency alarm prompt is carried out, so that danger is avoided. The value of the second preset duration can be set according to actual application requirements, which is not particularly limited in the invention.
Specifically, when the user runs, the wave crest or the wave trough in the running pressure data of the pressure sensor at each position is detected, the wave crest value is the user foot falling time point, the wave trough value is the foot lifting time point, the step frequency can be calculated by recording the wave crest or the wave trough in a period of time, the step frequency is monitored, if the short-time change exceeds a threshold value, for example, the step frequency is fast, slow, and the like, the step frequency confusion of the user is indicated, the user can not keep up at present, and early warning is carried out, so that danger is avoided.
S13, calculating the foot falling position of the current running action according to the running pressure data of the time point corresponding to the peak position, and calculating the real-time position of the user on the running machine after the foot falling according to the foot falling position of the current running action and the current running belt speed of the running machine.
In the embodiment, a preset first calculation model is specifically adopted to calculate the foot drop position P of the current running motion, wherein the first calculation model is as follows, p=aw1×p1+bw2×p2+cw3×p3+dw4×p1, P2, P3, P4 are respectively 2-dimensional position vectors of four pressure sensors located at four corners of the running board of the running machine, w1, w2, w3, w4 are running pressure data of four pressure sensors corresponding to a peak position time point closest to the current time, and a, b, c, d is a preset deviation adjusting parameter.
The offset parameter a, b, c, d is a preset fixed value. In an alternative embodiment, the value of the bias parameter a, b, c, d may be 1, indicating that all four sensors are unbiased. It can be appreciated that the specific value of the bias parameters a, b, c, d can be obtained through experimentation. For example, tire impact instruments with different weights can be used as experimental devices, pressure is applied to the running board at different corresponding positions, sensing data of pressure sensors corresponding to the experimental process are respectively acquired, and then preferable values of a, b, c, d are fitted by using calculation modes such as machine learning.
Specifically, the peak is the foot drop time, so that the peak in the running pressure data of the pressure sensors at all positions is obtained, the foot drop position of the current running can be calculated through an average algorithm of the first calculation model, when running, the user almost drags the running belt to move after the foot drop, and the real-time position of the user on the running machine after the foot drop can be calculated by combining the current speed with the foot drop position. Wherein the real-time position is the position of the foot on the treadmill at any time. The foot-falling position refers to a position that falls on the treadmill for an instant. The foot drop position is different from the real-time position because the foot drop is towed away after landing on the treadmill.
S14, calculating the foot lifting position of the next running action of the user according to the time point corresponding to the wave crest position and the wave trough position, the real-time position and the current running belt speed of the running machine.
In this embodiment, the foot lifting position of the next running action of the user is calculated according to the time points corresponding to the peak position and the trough position, the real-time position and the current running belt speed of the running machine, and specifically includes the following implementation steps of taking the time point corresponding to the trough position closest to the current time as foot lifting time and taking the time point corresponding to the peak position closest to the current time as foot falling time:
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 falling time), and the x coordinate value of the foot lifting position = the x coordinate value of the real-time position, wherein the running belt moving direction is set to be the y axis direction, and the direction perpendicular to the running belt moving direction on the same horizontal plane is set to be the x axis direction.
Specifically, the foot lifting time can be determined by judging the occurrence time of the trough position in the running pressure data of the pressure sensor at each position. The trough represents that the value acquired by the pressure sensor at the current moment is minimum, namely, no person steps on the trough in the corresponding movement process. For example, the direction of motion of the running belt is defined as the y-axis, and the direction perpendicular to the direction of motion of the running belt is defined as x, and then for the direction of motion of the running belt, 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 falling time), the perpendicular direction is defined as the x-coordinate value of the foot lifting position=the x-coordinate value of the real-time position.
And S15, judging whether the real-time position and/or the foot lifting position is in a preset dangerous position area on the running board of the running machine.
S16, when the real-time position and/or the foot lifting position is in a preset dangerous position area on the running board of the running machine, performing out-of-limit alarm prompt.
In the embodiment of the invention, a dangerous position area is preset on a running board of the running machine in advance, and in the running process, when the real-time position of the user on the running machine after falling feet and/or the foot lifting position of the next running action of the user are in the preset dangerous position area, real-time early warning is carried out, for example, if the falling feet position is too far left or right, the foot lifting position is too far after examination, and the like, out-of-limit warning prompt can be carried out.
According to the running state monitoring method provided by the embodiment of the invention, the running pressure data detected by the pressure sensors positioned at the four corners of the running plate of the running machine are analyzed, and the real-time position of the user on the running machine after the foot falls and the foot lifting position of the next running action of the user are calculated in real time, so that whether the user deviates from a running area or not is judged, the user is reminded in real time, the danger caused by the deviation of the user or the falling of the running machine is avoided, and the user experience is improved.
In addition, the running state of the running machine is monitored by adopting four sensors, the running machine is low in cost and easy to install, the prompting situation is rich through algorithm calculation, and the safety monitoring effect during exercise can be conveniently achieved.
It can be understood that, in order to further improve the running state monitoring accuracy, the design pressure sensors can be additionally arranged at other positions of the running board of the running machine, or a plurality of pressure sensors are arranged at four corners of the running board of the running machine to detect running pressure data, and the technical scheme of arranging 4 pressure sensors at four corners of the running board of the running machine is only used for explaining the technical scheme and is not particularly limited.
In the embodiment of the invention, before running pressure data of pressure sensors positioned at four corners of a running plate of a running machine are recorded in real time, sensor data acquired by the pressure sensors positioned at the four corners of the running plate of the running machine are acquired, whether a user climbs the running machine or not is monitored according to the sensor data, whether the running machine has hidden dangles in the hanging state currently is judged according to the sensor data acquired by each pressure sensor when the user climbs the running machine, if the hidden dangles in the hanging state exist, hanging alarm prompt is carried out, otherwise, the working state of the running machine is monitored, and the running pressure data operation of the pressure sensors at each position is recorded in real time when the running machine enters the running state.
In the embodiment of the invention, whether a user climbs onto the running machine or not can be monitored according to the sensor data acquired by the pressure sensors before exercise, and when the user climbs onto the running machine, whether the sensor data of each pressure sensor change consistently or not is judged, for example, three pressure sensor values are increased, one pressure sensor value is hardly increased, the corresponding position of the pressure sensor is not increased by the value, the running machine is suspended on uneven ground, and suspended placement hidden danger exists, and suspended alarm prompt is carried out at the moment, so that the danger caused by the exercise of the user is avoided.
In the embodiment of the invention, in order to ensure the accurate availability of data, the initial sensor data acquired by the pressure sensors positioned at four corners of the running board of the running machine can be acquired in the idle state of the running machine, and the pressure sensors are calibrated according to the initial sensor data.
Specifically, when the running machine is started, the value of the sensor is recorded for a period of time in the idle state of the running machine, the sensor is calibrated, and the current value is recorded. Further, sensor data may fluctuate, or illegal values may sometimes occur due to electromagnetic interference or the like, so that a filtering algorithm may also be adopted to ensure data consistency.
When the running machine is in idle load, the values of the pressure sensors are read, an average value in a period of time is recorded as initial sensor data of the corresponding pressure sensor by means of average value filtering, and when the data of the pressure sensors are read, difference processing can be carried out on the re-read data and the initial sensor data of the corresponding pressure sensor, so that calibration and calibration are completed. The results obtained in theory are zero values and actually float up and down around the zero values, so calibration is needed to achieve accurate analysis of the data.
The method further comprises the steps of recording running pressure data collected by pressure sensors at four corners of a running board of the running machine by taking a time point corresponding to the peak position as an index to form a queue, analyzing the landing pressures of left and right feet through the position relation of each pressure sensor and the running pressure data collected by each pressure sensor, and carrying out unbalanced early warning prompt in movement if the landing pressures of the left and right feet are in an unbalanced state continuously within a second preset duration. The value of the second preset duration can be set according to actual application requirements, which is not particularly limited in the invention.
Specifically, the invention can record the values of the sensors based on the time of the falling foot points to form a queue, judge the left foot and the right foot according to the position relation of the sensors, calculate the values of the left foot and the right foot to obtain the falling pressure, and if the falling of the two feet is always unbalanced for a period of time, early warning prompt is carried out in the movement.
Further, according to the position information of the pressure sensor, the peak value queue of the sensor is recorded, and whether the current foot falls on the left foot or the right foot can be distinguished through calculation. In an alternative embodiment, consider a queue formed by several consecutive footfalls, for two consecutive footfalls in the queue, if the sum of the left sensor values of the first footfall is greater than the sum of the right sensor values, and the sum of the left sensor values of the second footfall is less than the sum of the right sensor values, then the first footfall may be determined to be the left foot, and the second footfall may be determined to be the right foot. Assuming that the four sensor values are w1, w2, w3, w4 when the foot drop point is left foot, and u1, u2, u3, u4 when the foot drop point is right foot, it can be calculated that pr= (a×w1+b×w2+c×w3+d×w4)/(a×u1+b×u2+c×u3+d×u4) is a left and right foot drop pressure ratio, and a, b, c, d is a preset deviation adjustment parameter. When the ratio of the ground pressure of the left foot to the ground pressure of the right foot is larger than a certain preset threshold value or smaller than a certain preset threshold value for a continuous period of time, the imbalance of the ground pressure of the left foot and the ground pressure of the right foot of the user can be judged, and early warning prompt is carried out on the user.
According to the running state monitoring method provided by the embodiment of the invention, the running pressure data detected by the pressure sensors positioned at the four corners of the running plate of the running machine are analyzed, and the foot drop points of the user on the running machine are calculated in real time, so that whether the user deviates from a running area is judged, reminding is given in real time, and danger is avoided for the user. The reminding part mainly comprises whether the running machine is in an uneven position or not, so that the exercise is dangerous. If the walking frequency of the user is disordered, the foot falling position of the dangerous user is too deviated, and therefore the dangerous user can deviate or fall down the running machine, so that whether the left foot falling force and the right foot falling force of the dangerous user are inconsistent or not is caused, the running posture is incorrect, and some chronic injuries are caused.
