In the following description, reference is made to "some embodiments" which describe a subset of all possible embodiments, but it is to be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments and can be combined with one another without conflict.
In the following description, the terms "first", "second", "third" and the like are merely used to distinguish similar objects and do not represent a specific ordering of the objects, it being understood that the "first", "second", "third" may be interchanged with a specific order or sequence, as permitted, to enable embodiments of the invention described herein to be practiced otherwise than as illustrated or described herein.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein is for the purpose of describing embodiments of the invention only and is not intended to be limiting of the invention.
An embodiment of the present invention provides a sitting test system, as shown in fig. 1, including:
A first pressure sensor 1, a second pressure sensor 2, and a processor 3, wherein,
The first pressure sensor 1 is used for contacting the buttocks of a subject and generating a first signal indicating a first pressure value applied by the buttocks of the subject;
the second pressure sensor 2 is configured to contact the sole of the subject and generate a second signal indicative of a second pressure value applied by the sole of the subject;
The processor 3 is connected to the first pressure sensor 1 and the second pressure sensor 2, and is configured to determine a first duration and a second duration according to the first signal and the second signal, where the first duration is a duration from full standing to full sitting of the subject, and the second duration is a duration from full sitting to full standing of the subject.
In the embodiment of the invention, the sitting test may be to count the duration required by the subject to perform a certain number of sitting actions, so as to analyze the physical condition of the subject, for example, the duration required by 5 times of cyclic sitting actions.
Here, the pressure sensor is capable of detecting the pressure applied to its surface, and includes, but is not limited to: strain-type pressure sensors, vibrating wire type pressure sensors, eddy current pressure sensors, hall pressure sensors, etc. Preferably, the pressure sensor may be a variety of flexible pressure sensors of piezoresistive, capacitive, piezoelectric, etc. type to improve the sensitivity of detection of small changes in pressure. Because the pressure value applied by the buttocks and the sole is different in the fully standing posture and the fully sitting posture of the subject, the change condition of the sitting posture of the subject can be accurately determined by respectively detecting the change condition of the pressure value applied by the buttocks and the sole of the subject through the two pressure sensors.
It will be appreciated that the first signal may be a sensing signal carrying a first pressure value, and may also carry identification information of the first pressure sensor 1, so that the processor 3 determines that the pressure value carried in the signal is the first pressure value. The second signal is the same.
It can be understood that the first pressure sensor 1 and the second pressure sensor 2 can be connected with the processor 3 through signal lines, and also can be connected in a wireless manner such as WIFI, bluetooth and the like.
In one embodiment, the test may be performed by the subject once before the sitting test is started and once after the standing test is performed, the processor 3 records the first pressure value and the second pressure value corresponding to the fully sitting state and the fully standing state respectively, and sets the first pressure value and the second pressure value to the corresponding standard pressure value, and further determines whether the fully sitting and the fully standing postures are achieved according to whether the pressure values in the first signal and the second signal reach the standard pressure value after the test is started. Based on the moment when the full sitting and full standing positions are reached, the processor 3 can determine the length of time required for the sitting position transition.
Therefore, based on the detection of the pressure applied to the buttocks and the soles of the subjects, the time length from sitting to standing and from standing to sitting can be accurately and respectively determined on the basis of the determination of the sitting times, and the physical condition and the exercise capacity of the subjects can be more comprehensively and deeply analyzed.
In some embodiments, as shown in fig. 2, the sitting test system further comprises: a seat 4 and a standing area 5;
The seat 4 is fixedly provided with a first pressure sensor 1 for sitting down a subject;
The standing area 5 is fixedly provided with a second pressure sensor 2 for standing the subject.
It will be appreciated that during a sitting test of a subject, the fully seated position is required to be seated on the seat 4, and thus the first pressure sensor 1 is provided on the seat 4 and contacts the buttocks of the subject while the subject is sitting, and detects the first pressure value applied by the buttocks; the fully standing posture is required to stand in the standing area 5, and both feet of the subject are also located in the standing area 5 while sitting down, so that the second pressure sensor 2 is provided in the standing area 5, detecting the second pressure value applied by the sole of the foot.
In one embodiment, the height and distance of the seat 4 is adjustable compared to the standing area 5 for different subjects with different leg lengths and physical conditions to perform a sitting test in the most comfortable posture.
In some embodiments, the processor 3 determines the first time period and the second time period from the first signal and the second signal, including:
the processor 3 obtains a first pressure value according to the first signal and obtains a second pressure value according to the second signal;
The processor 3 determines the time when the number of times of sitting of the subject is increased by one according to the time when the first pressure value and/or the second pressure value starts to change from the completely standing state, and the first pressure value reaches the upper limit value of the hip pressure corresponding to sitting of the subject, and the second pressure value reaches the lower limit value of the plantar pressure corresponding to sitting of the subject, and determines the corresponding first duration;
The processor 3 determines the time when the number of times the subject stands up is increased by one according to the first pressure value and/or the second pressure value, and the time when the first pressure value reaches the lower limit value of the hip pressure corresponding to the standing of the subject and the second pressure value reaches the upper limit value of the plantar pressure corresponding to the standing of the subject, and determines the corresponding second duration.
In the embodiment of the invention, as the subject sits down fully, the buttocks contact the first pressure sensor 1 on the seat 4 to the greatest extent, and the sole applies the least pressure to the second pressure sensor 2 on the standing area 5; while in full standing the buttocks are not in contact with the first pressure sensor 1, whereas the sole of the foot applies the greatest pressure to the second pressure sensor 2.
In one embodiment, the upper and lower limits of the hip pressure and the upper and lower limits of the plantar pressure of the subject may be preset in the processor 3, for example, the first and second pressure values collected according to one test sitting of the subject before the sitting test starts may be respectively used as the upper and lower limits of the hip pressure and the first and second pressure values collected by the primary test station may be respectively used as the upper limits of the hip pressure and the upper limits of the plantar pressure.
It will be appreciated that the processor 3 may also preset the corresponding upper and lower hip pressure limits and upper and lower plantar pressure limits before the start of the test based on the subject's physical sign information, for example, based on the subject's weight and a certain calculation.
In another embodiment, both the upper and lower hip pressure limits and the upper and lower plantar pressure limits may be defined to avoid that the subject is under some exertion in a fully seated and fully standing position such that the detected pressure value does not reach the limit, resulting in inaccurate test results.
In one embodiment, the initial state of the subject at the beginning of the test may be a fully standing state, at which time the timing is started, at an initial time t 1, the first pressure value is at the lower hip pressure limit and the second pressure value is at the upper plantar pressure limit. When the subject performs a sitting action and reaches a fully sitting state, the buttocks contact the first pressure sensor 1 to the greatest extent, if the first pressure value is detected to reach the upper limit value of the buttocks pressure, and the second pressure value reaches the lower limit value of the plantar pressure, the situation that the subject reaches the fully sitting posture is indicated, and the moment is t 2. Therefore, the number of sitting down times can be determined to be increased by one, the total number of sitting down times is one, and the first duration used for sitting down at this time can be determined according to t 2-t1. If the initial state of the subject at the beginning of the test may also be a fully seated state, then the second period of time for standing is determined to be similar to the logic described above.
It will be appreciated that the transition of the subject from a fully seated to a fully standing state may be determined as the current stance onset time t 3 when the first and/or second pressure values change, or the amount of change that occurs reaches a threshold. If the first pressure value is detected to reach the lower hip pressure limit and the second pressure value reaches the upper plantar pressure limit, the situation that the subject has reached the full standing posture is indicated, and at the moment t 4. Thus, at this point, the number of stands may be determined plus one, and according to t 4-t3, the second period of time for stand may be determined.
Similarly, transitioning from a fully standing position to a fully seated position, determining the first time period for seating is similar to the logic described above.
Therefore, the time length from the standing posture to the sitting posture and the time length from the sitting posture to the standing posture can be accurately and respectively determined, and the posture of the subject can be accurately determined according to the hip pressure values and the plantar pressure values corresponding to different postures, so that finer calculation of the sitting time length is realized.
In some embodiments, the sitting testing system further comprises: and the man-machine interaction device 6 is connected with the processor 3 and used for outputting relevant information of sitting and standing tests.
The processor 3 is also configured to:
if the sitting times and the standing times of the testee reach the preset number, stopping counting and timing operations, and calculating the total duration according to the first duration and the second duration of the preset number;
and transmitting the preset number of first time periods, second time periods and total time periods to the man-machine interaction device.
In an embodiment of the present invention, the man-machine interaction device 6 may include: input units such as a keyboard, buttons, a touch screen and the like are used for inputting identity information of a subject; the system can also comprise a display screen, which is used for displaying the identity information of the subject and the sitting and standing test result of the subject, and can comprise the current times of sitting and standing of the subject, the time period respectively used from sitting to standing and standing to sitting, the total times of sitting and standing completed by the current sitting and standing test, the total time period and the like.
In one embodiment, the human-computer interaction device 6 may further include: the speaker for outputting voice and the microphone for collecting voice can output voice prompt information based on the speaker, for example, inquiring the age, sex, disease condition and the like of the subject, and can further obtain identity information of the age, sex, disease condition and the like of the subject based on voice signals corresponding to the answers of the subject collected by the microphone. The human-computer interaction device 6 may also output a voice instruction instructing the subject to perform the test action and a sitting test result of the subject based on the horn.
It can be understood that before the sitting test starts, the number of sitting times that the sitting test needs to be completed can be preset, for example, 5 times, and if it is statistically determined that the subject sits down 5 times and stands up 5 times, the sitting test ends, and counting and timing are stopped.
In one embodiment, the total duration of the test may be determined by adding up the corresponding 5 first durations of sitting down for 5 times and the corresponding 5 second durations of standing up for 5 times, or may be determined from the test start time to the test end time only according to a clock. The processor 3 may package all the first duration, the second duration and the total duration as the current sitting and standing test result, and send the result to the human-computer interaction device 6, for example, display the result on a display screen, or may output the test result through a speaker.
It can be understood that the human-computer interaction device 6 can display the time of sitting each time and the time of standing each time according to the sitting test process on the display screen, so as to facilitate visual analysis of the change of the physical condition of the subject along with the increase of the exercise amount and the increase of the exercise time.
In some embodiments, the processor 3 is further configured to:
And if a test stopping instruction is received, stopping counting and timing operations, and transmitting the current counted sitting times and standing times of the subject, and the corresponding first time length and second time length to the human-computer interaction device.
In the embodiment of the present invention, the instruction to stop the test may be issued by an operator, for example, the subject cannot continue the test and inform the operator, or the operator may issue the instruction to stop the test to the processor 3 after considering that the subject cannot continue.
In one embodiment, the stop test instruction may also be issued by the subject, for example, a stop button may be provided at the armrest of the seat 4, and the subject may press the stop button by himself to issue the stop test instruction to the processor 3 when an accident occurs or the physical condition is poor and cannot proceed.
It will be appreciated that, if the processor 3 receives the instruction to stop the test, it counts the total number of sitting and standing times that the current subject has completed, and the first duration and the second duration corresponding to each sitting and standing time, respectively, and sends the counted total number of sitting and standing times to the human-computer interaction device 6.
In some embodiments, as shown in fig. 3, the sitting test system further comprises:
Wearing the test assembly 7, comprising a first inertial sensor 71 bound to the thigh of the subject and a second inertial sensor 72 bound to the calf of the subject;
the processor 3 is connected to the first inertial sensor 71 and the second inertial sensor 72, respectively;
Accordingly, the processor 3 determines a first time period and a second time period from the first signal and the second signal, including:
The processor 3 determines a first time period and a second time period from the first signal and the second signal, and the data of the first inertial sensor 71 and the second inertial sensor 72.
In the embodiment of the present invention, the wearing test component 7 is a component that is bound to the lower limb of the subject, and can measure the posture information of the lower limb of the subject, for example, the wearing test component 7 may be a knee pad made of a material as a carrier, and the first inertial sensor 71 and the second inertial sensor 72 are fixed at two ends of the carrier at a certain interval, for example, the interval may be 30 cm, so as to implement that when the wearing test component 7 is bound to the leg of the subject, the first inertial sensor 71 is located at the thigh of the subject, and the second inertial sensor 72 is located at the calf of the subject.
Optionally, the mounting positions of the first inertial sensor 71 and the second inertial sensor 72 on the carrier may be adjustable, for example, the carrier may be provided with a plurality of mounting positions, and the mounting positions of the first inertial sensor 71 and/or the second inertial sensor 72 may be freely changed for subjects with different leg lengths, so as to keep the first inertial sensor 71 located at the thigh of the subject and the second inertial sensor 72 located at the calf of the subject.
In one embodiment, the first inertial sensor 71 and the second inertial sensor 72 are respectively used for acquiring posture information of the thigh and the calf, for example, the first inertial sensor 71 and the second inertial sensor 72 may be Micro-Electro-MECHANICAL SYSTEM, MEMS inertial sensors, when the posture of the lower limb changes due to sitting and standing actions of the subject, data information such as triaxial acceleration data and angle data of the thigh and the calf are respectively acquired, and after the data information is acquired, the processor 3 may combine initial data of the feet of the subject to determine posture information of the thigh and the calf, and further calculate a knee bending angle. Based on the change in the knee bending angle, the processor 3 can determine the posture change of the lower limb of the subject, thereby determining the completion of the sitting and standing actions of the subject.
In another embodiment, the first inertial sensor 71 and the second inertial sensor 72 may be connected to the processor 3 through signal lines, or may be connected to the processor 3 through wireless means such as WiFi or bluetooth.
Therefore, the change condition of the posture of the lower limb of the subject can be monitored by wearing the data of the inertial sensor in the test assembly 7, so that the completion condition of the sitting action of the subject can be more accurately determined, the completion time of the complete standing and the complete sitting of the subject is accurately defined, and the accuracy of the calculation of the first time length and the second time length is improved.
In some embodiments, the processor 3 determines the first and second durations from the first and second signals and the data of the first and second inertial sensors 71, 72, including:
the processor 3 obtains a first pressure value according to the first signal and obtains a second pressure value according to the second signal;
the processor 3 determines the knee bending angle of the subject according to the data of the first inertial sensor 71 and the second inertial sensor 72;
The processor 3 determines a first duration and a second duration based on the first pressure value, the second pressure value, and the knee bending angle.
In the embodiment of the present invention, the knee bending angle is an inner angle formed by the thigh and the calf of the subject, for example, when the subject is in a completely standing posture, the knee bending angle may be 180 degrees or close to 180 degrees; the knee bending angle may be 90 degrees or close to 90 degrees when the subject is in a fully seated position.
In one embodiment, processor 3 may determine the knee flexion angle of the subject from thigh and calf pose data acquired by first inertial sensor 71 and second inertial sensor 72.
It will be appreciated that in the process of the subject transitioning from the fully standing position to the fully seated position, i.e., in one sitting motion, the pressure applied by the buttocks, i.e., the first pressure value, tends to increase overall, the pressure applied by the sole, i.e., the second pressure value, tends to decrease overall, and the knee bending angle tends to decrease overall.
In the process of converting the subject from the fully seated posture to the fully standing posture, namely, in the primary standing action, the first pressure value tends to be reduced as a whole, the second pressure value tends to be increased as a whole, and the knee bending angle tends to be increased as a whole.
Therefore, according to the change condition of the knee bending angle, the change condition of the first pressure value and the second pressure value is combined, so that the progress condition of the sitting action of the subject can be more accurately determined, and the first duration and the second duration can be more accurately determined.
In some embodiments, the processor 3 determines the first duration and the second duration from the first pressure value, the second pressure value, and the knee angle, including:
The processor 3 determines that the sitting number of the subject is increased by one according to the moment when the first pressure value and/or the second pressure value changes from the completely standing state and the moment when the first pressure value reaches the upper limit value of the hip pressure corresponding to the sitting of the subject, the second pressure value reaches the lower limit value of the plantar pressure corresponding to the sitting of the subject and the knee bending angle reaches the lower limit value of the knee bending angle corresponding to the sitting of the subject, and determines the corresponding first duration;
The processor 3 determines that the number of times the subject stands up is increased by one according to the time when the first pressure value and/or the second pressure value changes from the fully seated state, and the time when the first pressure value reaches the lower limit value of the hip pressure corresponding to the standing of the subject, the second pressure value reaches the upper limit value of the plantar pressure corresponding to the standing of the subject, and the knee bending angle reaches the upper limit value of the knee bending angle corresponding to the standing of the subject, and determines the corresponding second duration.
In the embodiment of the invention, since the pressure value may reach the corresponding standard limit value in advance during the actual standing and sitting actions of the subject, for example, the first pressure value reaches the lower limit value of the hip pressure when the hip leaves the seat completely after the subject stands up from the seat, the body of the subject is still in a semi-standing state, and the second pressure value may be always at the upper limit value of the plantar pressure or reach the upper limit value of the plantar pressure in advance from the moment of leaving the seat to the moment of completely standing because the feet already bear the whole body weight of the subject. This results in the processor 3 determining in advance that the subject is fully standing, which in turn results in the second time period calculated by the processor 3 being shorter than the second time period actually used. Therefore, based on the variation of the knee bending angle, whether the subject is standing straight or not can be more accurately determined, and the subject is in a completely standing state only when the knee bending angle reaches the upper limit value of the knee bending angle.
It will be appreciated that the lower limit of the knee bending angle is reached when the subject is fully seated, wherein the lower limit of the knee bending angle may be a fixed value, such as 90 degrees, or may be a range, such as 90±5 degrees. Alternatively, the lower limit value of the knee bending angle may be preset according to the knee bending angle detected by the wearing test assembly 7 in the fully seated posture when the subject performs a sitting test before the test starts. The lower limit value of the knee bending angle can also be determined according to the physical characteristic information of the subject, for example, according to the height information of the subject, and the height and horizontal distance of the seat 4 relative to the standing area 5, so as to jointly determine the corresponding lower limit value of the knee bending angle when the subject is fully seated.
Accordingly, the upper limit of the knee bending angle may be a fixed value, for example, 180 degrees, or may be a range, for example, 170-180 degrees. Due to the age of different subjects, the skeletal conditions are different, resulting in different knee bending angles that can be formed by the lower extremities when fully standing. Therefore, the upper limit value of the knee bending angle can be preset according to the knee bending angle detected in the complete standing posture when the subject performs a trial standing motion before the test starts.
In one embodiment, the initial state of the subject at the beginning of the test may be a completely standing state, at which time the timing is started, the initial time is t 1, the first pressure value is at the lower limit value of hip pressure, the second pressure value is at the upper limit value of plantar pressure, and the knee bending angle is at the upper limit value of knee bending angle. After the subject performs a sitting motion, if it is detected that the first pressure value reaches the hip pressure upper limit value, the second pressure value reaches the plantar pressure lower limit value, and the knee bending angle reaches the knee bending angle lower limit value, this indicates that the subject reaches a fully seated posture, and at this time, time is t 2. Therefore, the number of sitting down times can be determined to be increased by one, the total number of sitting down times is one, and the first duration used for sitting down at this time can be determined according to t 2-t1. The initial state of the subject at the beginning of the test may also be a fully seated state, where the second period of time for the ascent to take is determined to be similar to the logic described above.
It will be appreciated that during the test, the subject may transition from a fully seated to a fully standing condition, and may change from the first pressure value and/or the second pressure value, or the amount of change generated may be determined to be the start time t 3 of the current station start when a certain threshold is reached. If the first pressure value is detected to reach the hip pressure lower limit value, the second pressure value reaches the plantar pressure upper limit value and the knee bending angle reaches the knee bending angle upper limit value, the situation that the subject has reached the full standing posture is indicated, and the moment is t 4. Thus, at this point, the number of stands may be determined plus one, and according to t 4-t3, the second period of time for stand may be determined. Similarly, transitioning from a fully standing position to a fully seated position, determining the first time period for seating is similar to the logic described above.
In some embodiments, the test assembly 7 is worn, disposed on a leg on one side of the subject, or disposed on the left and right legs of the subject, respectively.
In the embodiment of the invention, as the two legs of the subject always synchronously perform the action and the posture change in the sitting and standing action, the wearing test assembly 7 can be arranged on only one leg of the subject, and the accurate acquisition of the posture of the lower limb of the subject can be realized.
However, some subjects are older, or otherwise have limited physical movement, such that a balance is maintained by the need for two feet in tandem support during sitting. Therefore, the posture of the left leg and the knee bending angle of the left knee and the right leg of the subject may be inconsistent during the sitting and standing actions, at this time, the wearing test assembly 7 may also be respectively disposed on the left leg and the right leg, that is, the left leg is provided with a set of first inertial sensor 71 and second inertial sensor 72, and the right leg is also provided with a set of first inertial sensor 71 and second inertial sensor 72, so as to comprehensively and accurately monitor the posture change of the lower limb of the subject and the action completion condition.
As shown in fig. 4, an embodiment of the present invention provides a sitting testing method applied to a sitting testing system, the sitting testing method including:
S110: acquiring a first pressure value applied by buttocks and a second pressure value applied by soles of the testee;
s120: determining a first time period and a second time period according to the first pressure value and the second pressure value; the first time period characterizes a time period for the subject to stand from full to full sitting, and the second time period characterizes a time period for the subject to stand from full to full sitting.
In the embodiment of the invention, the first pressure value can be obtained through a pressure sensor arranged on the upper surface of the seat and contacted with the buttocks of the subject, and the second pressure value can be obtained through a pressure sensor arranged on the upper surface of the standing area of the feet of the subject and contacted with the soles of the feet of the subject. Here, the pressure sensor may include various pressure sensors such as piezoresistive type, capacitive type, piezoelectric type, and the like, and other sensors may be used instead.
Therefore, the time when the subject reaches the fully seated state and the fully standing state can be more accurately determined by combining the change condition of the pressure applied by the buttocks and the soles of the subject, and further the first time required by the seating action and the second time required by the standing action can be accurately determined.
In some embodiments, as shown in fig. 5, S120 includes:
S121: from the moment when the first pressure value and/or the second pressure value starts to change in the completely standing state, if the first pressure value reaches the upper limit value of the hip pressure corresponding to the sitting of the subject and the second pressure value reaches the lower limit value of the plantar pressure corresponding to the sitting of the subject, determining the first time length for the change process of the first pressure value and the second pressure value;
S122: and from the moment when the first pressure value and/or the second pressure value starts to change in the fully seated state, if the first pressure value reaches the lower limit value of the hip pressure corresponding to the standing of the subject and the second pressure value reaches the upper limit value of the plantar pressure corresponding to the standing of the subject, determining the second duration of the change process of the first pressure value and the second pressure value.
In the embodiment of the invention, when the subject sits down completely, the pressure applied by the buttocks reaches the upper limit value, and the pressure applied by the sole reaches the lower limit value; when the subject stands completely, the pressure applied by the buttocks reaches the lower limit value, and the pressure applied by the sole reaches the upper limit value.
In one embodiment, the first time period for which the first pressure value and the second pressure value are changed may be determined, and the time period elapsed after the previous time period calculation is completed may be the first time period from the first time point when the first pressure value and the second pressure value start to change until the first pressure value reaches the upper limit value of hip pressure and the second pressure value reaches the lower limit value of plantar pressure.
It will be appreciated that determining the first time period for which the first pressure value and the second pressure value change process continue may be determining the third time period from when the first pressure value and the second pressure value start to change after the previous time period calculation is completed until the fourth time period when the first pressure value reaches the lower limit value of the hip pressure and the second pressure value reaches the upper limit value of the plantar pressure, where the elapsed time period is the second time period.
In some embodiments, as shown in fig. 6, the sitting test method further comprises:
S100: obtaining a knee bending angle;
accordingly, S120 includes:
s123: and determining a first duration and a second duration according to the first pressure value, the second pressure value and the knee bending angle.
In the embodiment of the invention, the knee bending angle can be obtained through a wearing test assembly arranged on the lower limb of the subject, for example, the wearing test assembly comprises a first inertial sensor respectively positioned on the thigh of the subject and a second inertial sensor positioned on the calf of the subject, and the included angle formed by the thigh and the calf of the subject, namely the knee bending angle of the subject, can be calculated according to the data of the first inertial sensor and the second inertial sensor.
Therefore, according to the combination of the knee bending angle and the pressure value, the moment when the subject reaches the complete standing and the complete sitting can be more accurately determined, so that the first time length and the second time length are more accurately calculated, and the error of the body posture judgment of the subject due to different body conditions is avoided.
In some embodiments, as shown in fig. 7, S123 includes:
S123a: from the moment when the first pressure value and/or the second pressure value starts to change in the completely standing state, if the first pressure value reaches the upper limit value of the hip pressure corresponding to the sitting of the subject, the second pressure value reaches the lower limit value of the plantar pressure corresponding to the sitting of the subject, and the knee bending angle reaches the lower limit value of the knee bending angle corresponding to the sitting of the subject, determining the corresponding first duration;
S123b: and from the moment when the first pressure value and/or the second pressure value starts to change in the fully seated state, if the first pressure value reaches the lower limit value of the hip pressure corresponding to the standing of the subject, the second pressure value reaches the upper limit value of the plantar pressure corresponding to the standing of the subject, and the knee bending angle reaches the upper limit value of the knee bending angle corresponding to the standing of the subject, determining the corresponding second duration.
In the embodiment of the present invention, if the current time is the first time after the sitting test starts, based on the initial state at the time of starting the test, the time period elapsed from the time when at least one of the first pressure value, the second pressure value and the knee bending angle changes until the time when the first pressure value, the second pressure value and the knee bending angle all reach the corresponding limit value of sitting or the corresponding limit value of standing is the first time period or the second time period.
In an embodiment, the determining the first time period for the first pressure value, the second pressure value, and the knee bending angle change process may be determining a time period when at least one of the first pressure value, the second pressure value, and the knee bending angle changes and reaches a certain value after the previous time period is calculated, where the certain value may be a time period when the pressure value change reaches 30N, or the knee bending angle change reaches 5 degrees, until the time period when the first pressure value, the second pressure value, and the knee bending angle reach the corresponding limit values for sitting, and the time period elapsed is the first time period. The determination of the second time period is the same.
Therefore, corresponding limit values are set for the first pressure value, the second pressure value and the knee bending angle of the subject, which correspond to the complete standing and complete sitting, so that the definition of the moment of completion of the sitting action is more accurate, and the first duration and the second duration can be more accurately determined.
