Technical Field
[0001] The present application relates to the field of computer technology, and in particular to a method, device, and equipment for monitoring riding posture. Background Art
[0002] Cycling, as a healthy and natural form of exercise, is loved by more and more people. However, many cycling enthusiasts suffer varying degrees of sports injuries to the knee and ankle joints due to incorrect riding postures. In severe cases, it may also cause inflammation of the inner and outer sides of the knee joints.
[0003] At present, the riding posture monitoring method usually needs to first use a wearable device to obtain the motion state data of the rider during riding, and then determine whether the rider's riding posture is correct based on the motion state data obtained by the wearable device. The existing riding monitoring method uses a wearable device to obtain the motion state data of the rider during riding, which usually requires the rider to wear the wearable device on the body, such as fixing the wearable device on the rider's knees or soles of the feet, which affects the rider's riding comfort. Based on this, how to provide a simple riding posture monitoring method that does not require the use of a wearable device to obtain the rider's motion state data has become a technical problem that needs to be solved urgently. Summary of the invention
[0004] The embodiments of this specification provide a method for monitoring the riding posture of a bicycle to solve the problem that the existing methods for monitoring the riding posture of a bicycle are complicated.
[0005] To solve the above technical problems, the embodiments of this specification are implemented as follows: A bicycle riding posture monitoring method, the method comprising: Acquiring motion posture data of a pedal connected to the crank; the motion posture data is acquired by a first sensor disposed on the pedal; Determine the angle between the foot pedal and the horizontal plane according to the motion posture data; Determine whether the angle between the foot pedal and the horizontal plane is within a first preset angle range, and obtain a first determination result; If the first judgment result indicates that the angle between the pedal and the horizontal plane is not within the first preset angle range, a first prompt message is generated; the first prompt message is used to prompt the user that the current riding posture is incorrect.
[0006] A bicycle riding posture monitoring device, the device comprising: An acquisition module, used for acquiring motion posture data of a pedal connected to the crank; the motion posture data is acquired by a first sensor arranged on the pedal; A determination module, used for determining the angle between the foot pedal and the horizontal plane according to the motion posture data; A judgment module, used for judging whether the angle between the foot pedal and the horizontal plane is within a first preset angle range, and obtaining a first judgment result; The information generating module is used to generate a first prompt message if the first judgment result indicates that the angle between the pedal and the horizontal plane is not within the first preset angle range; the first prompt message is used to prompt the user that the current riding posture is incorrect.
[0007] At least one embodiment of the present specification can achieve the following beneficial effects: using the first sensor disposed on the pedal to obtain the motion posture data of the pedal; determining the angle between the pedal and the horizontal plane based on the motion posture data. Since the sole of the user fits against the pedal during riding, the angle between the pedal and the horizontal plane is the angle between the sole of the user and the horizontal plane. Then, determining whether the user's riding posture is correct based on the angle between the sole of the foot and the horizontal plane, and generating a prompt message when the user's riding posture is incorrect, thereby preventing the user from suffering physical injuries due to incorrect riding posture. At the same time, the first sensor is installed on the pedal, and the first sensor installed on the pedal is used to obtain motion posture data that can reflect the posture of the user's sole, thereby avoiding the user from having to wear a wearable device every time riding, reducing user operations, and avoiding affecting the user's riding comfort.

[0011] In order to make the purpose, technical solutions and advantages of one or more embodiments of this specification clearer, the technical solutions of one or more embodiments of this specification will be clearly and completely described below in combination with the specific embodiments of this specification and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of one or more embodiments of this specification.
[0012] The technical solutions provided by the embodiments of this specification are described in detail below in conjunction with the accompanying drawings.
[0013] Figure 1 is a schematic diagram of a bicycle structure provided in an embodiment of this specification; Figure 1 As shown, the bicycle may include a frame 1, a wheel 2, a crank 3, a pedal 4, and a seat 5; wherein the crank 3 may include a first crank 31 and a second crank 32 respectively arranged on both sides of the frame 1, and the pedal 4 may include a first pedal 41 and a second pedal 42 connected to the first crank 31 and the second crank 32.
[0014] Figure 2 This is a flow chart of a bicycle riding posture monitoring method provided in an embodiment of this specification. From a program perspective, the execution subject of this process can be a server or a controller set on the bicycle.
[0015] like Figure 2 As shown, the process may include the following steps.
[0016] Step 202: Acquire motion posture data of a pedal connected to a crank; the motion posture data is acquired by a first sensor disposed on the pedal.
[0017] In the embodiments of this specification, the bicycle can be a spinning bicycle or a bicycle. One end of the crank in the bicycle can usually be arranged at the axis of the wheel disc of the bicycle, and the other end is connected to the pedal of the bicycle.
[0018] The first sensor may be a component that can measure the movement direction, angle and other postures of an object. Specifically, the first sensor may be at least one of an inertial measurement unit (IMU), a three-axis accelerometer, a six-axis accelerometer, and a gyroscope. It is understandable that the motion posture data of the pedal measured and collected by different types of first sensors may be different. The inertial measurement unit is composed of a three-axis accelerometer and a gyroscope, so that the motion posture data measured by the inertial measurement unit is more accurate than the motion posture data measured by other single sensors. In order to ensure the reliability of the data and the convenience of sensor installation in the embodiments of this specification, an inertial measurement unit may be preferably used.
[0019] In the embodiment of this specification, the motion posture data is data that can reflect the posture of the pedal angle, etc. Since the user's foot fits the pedal of the bicycle during riding, the motion posture data of the pedal can reflect both the posture of the pedal and the posture of the user's foot during riding.
[0020] In practical applications, a mounting vehicle for protecting and installing the first sensor can be designed according to the plane of the pedal. The mounting vehicle can be provided with a limiting mechanism to facilitate the installation of the first sensor and reduce the adjustment of the first sensor during the installation process.
[0021] In the embodiment of the present specification, the first sensor is installed on the pedal, and the first sensor installed on the pedal is used to obtain motion posture data that can reflect the posture of the user's foot, thereby avoiding the user from wearing a wearable device every time riding, simplifying user operation, and avoiding affecting the user's riding comfort.
[0022] Step 204: Determine the angle between the foot pedal and the horizontal plane according to the motion posture data.
[0023] In the embodiments of the present specification, since the soles of the user's feet are in contact with the pedals during riding, the angle between the pedals and the horizontal plane is the angle between the soles of the user's feet and the horizontal plane.
[0024] During riding, if the pedal is not parallel to the horizontal plane, that is, there is a certain angle between the pedal and the horizontal plane, it can be said that the heel and toe of the user are not on the same horizontal plane during riding.
[0025] In practical applications, an accelerometer can be used to measure the linear acceleration of the pedal, that is, the rate of change of velocity; the linear acceleration of the pedal on the three coordinate axes can be used to infer the direction of the pedal, so as to obtain the angle between the pedal and the horizontal plane. A gyroscope can also be used to measure the angular velocity of the pedal, that is, the rate of change of angle; the angular velocity of the pedal on the three coordinate axes can be used to infer the direction of the pedal, so as to obtain the angle between the pedal and the horizontal plane. An inertial measurement unit can also be used to infer the direction of the pedal by combining the linear acceleration of the pedal measured by the accelerometer in the inertial measurement unit and the angular velocity of the pedal measured by the gyroscope to obtain the angle between the pedal and the horizontal plane.
[0026] Step 206: Determine whether the angle between the foot pedal and the horizontal plane is within a first preset angle range, and obtain a first determination result.
[0027] Figure 3 is a schematic diagram of the angle between a foot pedal and a horizontal plane provided in an embodiment of this specification, such as Figure 3 As shown, in the embodiment of the present specification, since the sole 8 of the user is in contact with the pedal during riding, the angle 7 between the pedal and the horizontal plane 6 is the angle between the sole 8 of the user and the horizontal plane 6.
[0028] In the embodiment of this specification, the angle formed by the plane where the pedal is located rotating counterclockwise along the horizontal plane 6 can be regarded as positive, and the angle formed by the plane where the pedal is located rotating clockwise along the horizontal plane 6 can be regarded as negative. Figure 3 As shown, the angle 7 between the foot pedal and the horizontal plane 6 is the angle formed by the plane where the foot pedal is located rotating clockwise along the horizontal plane 6, and the angle value of the angle is negative.
[0029] In practical applications, the first preset angle range can be set according to actual needs. During riding, for the circumferential area formed by the rotation of the crank, the first preset angle range set at different positions can be different. For example, for the area at the lower part of the circumferential area, the first preset angle range can be -15°~0°.
[0030] Step 208: If the first judgment result indicates that the angle between the pedal and the horizontal plane is not within the first preset angle range, a first prompt message is generated; the first prompt message is used to prompt the user that the current riding posture is incorrect.
[0031] If the angle between the pedal and the horizontal plane is within the first preset angle range, it may indicate that the user's riding posture is correct, and no prompt information may be generated at this time; if the angle between the pedal and the horizontal plane is not within the first preset angle range, it may indicate that the user's riding posture is incorrect, and at this time, a prompt information may be generated to prompt the user to correct the current riding posture.
[0032] In practical applications, an information prompt element may be provided on the bicycle to output prompt information to remind the user when the user's riding posture is incorrect.
[0033] Specifically, the information prompt element may be a visual prompt element; for example, a display screen or an indicator light, which may be used to display text prompt information to prompt the user that the current riding posture is incorrect. The indicator light may also be used to light up in a preset color or flash at a preset frequency to display prompt information. The information prompt element may also be an auditory prompt element, for example, a voice prompt element, which may be used to output voice prompt information; the information prompt element may also be a tactile prompt element, for example, a vibration prompt element, which may be used to generate vibration according to a preset rule to prompt the user that the current riding posture is incorrect.
[0034] During cycling, when the pedals rotate with the cranks to the lowest point and the area near the lowest point, it is usually the riding force range; especially when the user is standing and riding or the seat position is adjusted higher, the probability that the thigh and calf are in a straight line is also high, which may cause knee injuries. Therefore, the monitoring area can include the area near the lowest point when the crank is at the lowest point during cycling.
[0035] Optionally, the acquiring of the motion posture data of the pedal connected to the crank may specifically include: The motion posture data of the pedal is obtained when the crank passes through a preset area during the riding process of the user.
[0036] In the embodiment of this specification, the preset area can be the area near the lowest point when the crank passes the lowest point during rotation. Specifically, the preset area can be the area within the second preset angle range before the crank passes the lowest point during riding, and the area within the third preset angle range after the crank passes the lowest point.
[0037] In practical applications, the second preset angle may be 0° to 30°; the third preset angle may be 0° to 30°; the second preset angle and the third preset angle may be the same or different.
[0038] When the crank passes through the preset area, especially when the user is standing and riding, if the toes are slightly lower than the heels, the thigh and calf are usually not in the same straight line, which can effectively prevent the knee from being injured by the impact of body weight. On the contrary, if the toes are slightly higher or flatter than the heels during riding, the thigh and calf may be in the same straight line, which may cause the knee to be injured by the impact of the human body. At this time, the posture of the user's legs can be determined based on the posture of the pedals, that is, the posture of the user's soles, so as to monitor whether the riding posture of the user's legs is correct during riding.
[0039] Specifically, if the angle between the pedal and the horizontal plane is within the first preset angle range, that is, the user's toe position is lower than the heel position; at this time, it can be determined that the thigh and the calf are not in the same straight line, so that the knee can be effectively prevented from being injured by the impact of body weight; if the angle between the pedal and the horizontal plane is not within the first preset angle range, that is, the toe position is higher than the heel position or is level with the heel position, the thigh and the calf may be in the same straight line, which may cause the knee to be injured by the impact of the human body. At this time, a prompt message can be generated to remind the user that the current riding posture is incorrect.
[0040] In the embodiments of the present specification, monitoring the riding posture of the user in the preset area can effectively reduce the physical damage caused by incorrect riding posture of the user during riding.
[0041] In practical applications, a sensor may be used to detect whether the crank is located in a preset area or is passing through a preset area.
[0042] Specifically, the step of obtaining the motion posture data of the pedal when the crank passes through a preset area during the riding process of the user may include: Determine whether the second sensor outputs a detection signal; the second sensor can be used to output a detection signal when it detects that the crank passes through the preset area.
[0043] If yes, the motion posture data of the pedal is obtained.
[0044] In the embodiments of this specification, a second sensor can be used to detect whether the crank is passing through a preset area. The second sensor can be set on the frame directly below the axis of the bicycle wheel. In practical applications, the sensing area of the second sensor can be adjusted by adjusting the parameters of the second sensor; specifically, the sensing area of the second sensor can be adjusted to a preset area, so that the sensor can detect the crank passing through the preset area.
[0045] The second sensor may be a photoelectric sensor or a Hall sensor, or other sensors, which are not specifically limited here.
[0046] According to user needs, the riding posture of one leg can be monitored, or the riding posture of both legs can be monitored. It is understandable that when it is necessary to monitor whether the riding posture of the user's legs is correct, it is usually necessary to obtain the motion posture data of the left pedal when the left crank passes through the preset area, and the motion posture data of the right pedal when the right crank passes through the preset area.
[0047] Specifically, the detection signal may be a first detection signal or a second detection signal. The first detection signal may be used to reflect that the first crank in the cranks passes through the preset area during the riding process of the user; the second detection signal may be used to reflect that the second crank in the cranks passes through the preset area during the riding process of the user.
[0048] The obtaining of the motion posture data of the pedal may specifically include: When the second sensor outputs the first detection signal, motion posture data of the pedal connected to the first crank is acquired.
[0049] When the second sensor outputs a second detection signal, motion posture data of a pedal connected to the second crank is acquired.
[0050] In the embodiments of this specification, the first crank and the second crank may be cranks located on different sides; specifically, the first crank may be the crank on the left side, and the second crank may be the crank on the right side; of course, the first crank may also be the crank on the right side, and the second crank may be the crank on the left side.
[0051] The first detection signal may be a signal output by the second sensor when the second sensor detects that the first crank passes through a preset area; the second detection signal may be a signal output by the second sensor when the second crank passes through a preset area.
[0052] In practical applications, a photoelectric sensor can be used to detect whether the first crank and the second crank have passed through a preset area. Specifically, two photoelectric sensors with opposite detection directions can be set on the frame directly below the axis of the bicycle wheel, wherein the first photoelectric sensor can be used to detect whether the first crank has passed through a preset area, and when the first crank is detected to have passed through the preset area, the first photoelectric sensor can output a first detection signal; the second photoelectric sensor can be used to detect whether the right crank has passed through a preset area, and when the second crank is detected to have passed through the preset area, the second photoelectric sensor can output a second detection signal. It is understandable that if only the riding posture of a user's unilateral leg (left leg or right leg) needs to be monitored, a corresponding photoelectric sensor can be installed.
[0053] In addition, the Hall sensor can also be used to detect whether the first crank and the second crank have passed through the preset area. Specifically, a Hall sensor can be set on the frame directly below the axis of the wheel disc of the bicycle, and two magnets with opposite polarities can be set respectively at the positions close to the pedals in the orthographic projection of the two cranks on the wheel disc. The above-mentioned Hall sensor can be a linear Hall sensor. Since the wheel disc rotates coaxially with the crank, the linear Hall sensor can detect whether the crank is located in the preset area by detecting the magnet set on the wheel disc. When the linear Hall sensor determines that the first crank has passed through the preset area according to the polarity of the magnet, it can output a first detection signal; when the linear Hall sensor determines that the second crank has passed through the preset area according to the polarity of the magnet, it can output a second detection signal. In practical applications, two magnets with opposite polarities can also be directly set at the positions of the two cranks close to the pedals. It can be understood that if it is only necessary to monitor the riding posture of the user on one side (left or right), only one magnet can be installed on the corresponding wheel disc or crank.
[0054] In the embodiments of the present specification, whether the riding posture on the same side as the first crank is correct can be determined based on the motion posture data of the pedal connected to the first crank; and whether the riding posture on the same side as the second crank is correct can also be determined based on the motion posture data of the pedal connected to the second crank.
[0055] During riding, when the riding posture on the left side or the riding posture on the right side is incorrect, prompt information can be generated for the riding posture on the left side and the riding posture on the right side respectively, so that the user can clearly identify the correct riding posture and the incorrect riding posture, thereby guiding the user to ride according to the correct riding posture.
[0056] Optionally, the generating prompt information may specifically include: Generate a first prompt message, where the first prompt message can be used to prompt the user that the riding posture on the same side of the first crank is incorrect; or, A second prompt message is generated, where the second prompt message can be used to prompt the user that the riding posture on the same side of the second crank is incorrect.
[0057] In an embodiment of the present specification, when it is determined based on the motion posture data of the pedal connected to the first crank that the angle between the pedal connected to the first crank and the horizontal plane is not within a first preset angle range, it can be determined that the riding posture on the same side as the first crank is incorrect. At this time, a first prompt message can be generated to prompt that the riding posture on the same side as the first crank is incorrect.
[0058] When it is determined based on the movement posture data of the pedal connected to the second crank that the angle between the pedal connected to the second crank and the horizontal plane is not within the first preset angle range, it can be determined that the riding posture on the same side as the second crank is incorrect. At this time, a second prompt message can be generated to prompt that the riding posture on the same side as the second crank is incorrect.
[0059] In actual applications, if the number of times the first prompt message or the second prompt message is continuously generated exceeds a preset number, in order to avoid causing damage to the user, an alarm message may be generated to warn the user; the user may also be forced to stop riding by controlling the bicycle braking system.
[0060] When the user's riding posture on the left side or the right side is incorrect, prompt information is generated for the riding posture on the left side and the riding posture on the right side respectively, which can help the user to clearly identify the correct riding posture and the incorrect riding posture and correct the incorrect riding method.
[0061] In practical applications, in order to facilitate the acquisition of motion posture data of the pedal connected to the crank in the preset area, the first sensors on the two pedals can be matched with the two cranks in advance when installing the first sensor. For example, the first sensors on the two pedals are installed correspondingly with the two cranks, or the first sensors on the two pedals are installed randomly. After the installation is completed, the address for storing the motion posture data obtained by the first sensor corresponding to the first crank and the address for storing the motion posture data obtained by the first sensor corresponding to the second crank are modified accordingly; but this undoubtedly increases the difficulty of operation for customers. Based on this, the embodiment of this specification provides a method for obtaining motion posture data of the pedal connected to the crank in the preset area.
[0062] Optionally, the first pedal and the second pedal of the pedals may both be provided with the first sensor; and the step of acquiring the motion posture data of the pedal connected to the first crank may specifically include: The motion posture data of the first foot pedal and the motion posture data of the second foot pedal are acquired.
[0063] The direction of the acceleration of the first foot pedal is determined according to the acceleration data in the motion posture data of the first foot pedal.
[0064] The direction of the acceleration of the second foot pedal is determined according to the acceleration data in the motion posture data of the second foot pedal.
[0065] According to the direction of the acceleration of the first pedal and the direction of the second pedal, the motion posture data of the pedal connected to the first crank is determined.
[0066] In actual application, when the first crank passes through the preset area, since the pedal rotates with the crank, according to the force analysis, the centripetal acceleration of the pedal connected to the first crank is upwardly directed toward the center of the circle. And when the first crank passes through the preset area, the second crank is located at the upper part of the circumferential area formed by the rotation of the second crank; according to the force analysis, the direction of the centripetal acceleration of the pedal connected to the second crank is downwardly directed toward the center of the circle. Therefore, the direction of the acceleration of the first pedal can be determined according to the motion posture data of the first pedal; the direction of the acceleration of the second pedal can be determined according to the motion posture data of the second pedal; the motion posture data of the pedal connected to the first crank can be determined according to the direction of the acceleration of the first pedal and the direction of the acceleration of the second pedal.
[0067] Similarly, when the second crank passes through the preset area, the motion posture data of the pedal connected to the second crank can be determined using a similar method as described above, which will not be repeated here.
[0068] In the embodiments of the present specification, required motion posture data is determined and screened according to the characteristics of the data, so that when the user installs the first sensor in the first pedal and the second pedal, there is no need to distinguish between the first sensor in the first pedal and the first sensor in the second pedal, and there is no need to set the correspondence between the first sensor in the first pedal and the first sensor in the second pedal and the first crank and the second crank, thereby simplifying the process of users installing and setting the first sensor, reducing the difficulty of users' operation, and improving convenience.
[0069] Based on the same idea, the embodiments of this specification also provide a device corresponding to the above method. Figure 4 This is a schematic diagram of the structure of a bicycle riding posture monitoring device provided in an embodiment of this specification.

[0070] The determination module 404 is used to determine the angle between the foot pedal and the horizontal plane according to the motion posture data.
[0071] The judgment module 406 is used to judge whether the angle between the foot pedal and the horizontal plane is within a first preset angle range, and obtain a first judgment result.
[0072] The information generating module 408 is used to generate a first prompt message if the first judgment result indicates that the angle between the pedal and the horizontal plane is not within the first preset angle range; the first prompt message is used to prompt the user that the current riding posture is incorrect.
