[0019] The technical scheme of the embodiments of the present application will be described clearly and completely below with reference to the drawings of the embodiments of the present application. Figure 1 - The drawings Figure 4 The technical scheme of the embodiments of the present application will be described clearly and completely below with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present application.

[0020] Reference should be first made to Figure 1 The utility model provides a kind of body balance function training platform 1000, wherein the body balance function training platform 1000 includes measuring device 100, and the measuring device 100 includes bearing platform 1, pressure measurement module 2, microcontroller 3 and host computer 4.

[0021] Among them, bearing platform 1 has installation cavity 110, and installation cavity 110 is used to provide the installation space required by other modules of measuring device 100.

[0022] The pressure measurement module 2 is located in the installation cavity 110, and the pressure measurement module 2 comprises at least three pressure sensors 20, which are used to detect at least pressure values to obtain data information required by the measuring device 100. At least two pressure sensors 20 are arranged along the first direction X, and at least two pressure sensors 20 are arranged along the second direction Y, so that at least one pressure sensor 20 is arranged at different bearing areas of the bearing table 1 to measure external forces acting on the surface of the bearing table 1.

[0023] The microcontroller 3 is electrically connected with the pressure measurement module 2, and the microcontroller 3 is used to determine weight data according to the pressure values detected by the at least three pressure sensors 20. The weight data obtained by the pressure values of the plurality of pressure sensors 20 has higher accuracy, and the plurality of pressure sensors 20 can multi-dimensionally feedback stress information of the bearing table 1, so that the influence of the measurement error of the bearing table 1 caused by uneven stress is reduced to a certain extent.

[0024] The host computer 4 is in communication connection with the microcontroller 3, and the host computer 4 is used to receive the pressure values from the at least three pressure sensors 20 through the microcontroller 3, and determine the gravity center data according to the pressure values of the at least three pressure sensors 20. The use object of the host computer 4 can obtain the gravity center data of the to-be-measured subject through the host computer 4, so as to judge the position of the to-be-measured subject relative to the measuring device 100, or the balance ability of the to-be-measured subject itself.

[0025] In the embodiment, the host computer 4 and the controller can be connected through Bluetooth or physical wires, and no additional limitation is made in the embodiment.

[0026] In an implementable manner, when evaluating the balance ability of the to-be-measured subject, the to-be-measured subject can move according to the test instruction, the host computer 4 obtains the actual gravity center trajectory of the to-be-measured subject in the moving process according to the pressure values of the pressure sensors 20, and compares the actual gravity center trajectory with the preset balance gravity center trajectory of the measuring device 100, and judges the balance ability of the to-be-measured subject by comparing the coincidence degree of the two trajectories.

[0027] It should be noted that the to-be-measured subject mentioned above and the use object mentioned above can be the same or different. For example, when the to-be-measured subject and the use object are both people, the to-be-measured subject can be personnel using the measuring device 100, such as medical personnel, and the use object can be a person holding the host computer 4, such as a doctor, or the to-be-measured subject and the use object are the same person, and the person is used as the to-be-measured subject of the measuring device 100, and can also obtain the measurement data (at least including the weight data and the balance ability evaluation data) of the person through the feedback of the host computer 4.

[0028] The application provides a measuring device 100 capable of evaluating the balance ability of a to-be-tested subject, wherein the measuring device 100 is also capable of measuring the weight of the to-be-tested subject, in other words, the measuring device 100 is capable of measuring the weight of the to-be-tested subject and evaluating the balance ability of the to-be-tested subject, and the part of information can be fed back to a user by a host computer 4, so that the user can comprehensively understand the condition of the to-be-tested subject, and the requirement of the user group can be met, and the complexity of the requirement of the user group in using the measuring device 100 to measure multiple data is reduced.

[0029] Reference can be made to Figure 2 Further, the pressure sensor 20 comprises a first pressure detection element 201 and a second pressure detection element 202, one end of the first pressure detection element 201 is electrically connected with a reference voltage, the other end of the first pressure detection element 201 is electrically connected with one end of the second pressure detection element 202 and the first center voltage end 21, and the other end of the second pressure detection element 202 is grounded, and it should be noted that when the pressure sensor 20 is subjected to pressure, the first pressure detection element 201 and the second pressure detection element 202 will change in resistance under the action of the pressure, in other words, the first pressure detection element 201 and the second pressure detection element 202 can be understood as a pressure-sensitive resistor (or a force-sensitive resistor).

[0030] The pressure measuring module 2 further comprises a reference voltage circuit 6, and the reference voltage circuit 6 comprises a first reference resistor 60 and a second reference resistor 61, one end of the first reference resistor 60 is electrically connected with a reference voltage, the other end of the first reference resistor 60 is electrically connected with one end of the second reference resistor 61 and a center reference voltage end 62, and the other end of the second reference resistor 61 is grounded, and it should be noted that in the reference voltage circuit 6, the resistance of the first reference resistor 60 and the second reference resistor 61 does not change, in other words, the first reference resistor 60 and the second reference resistor 61 are fixed resistors.

[0031] In the first aspect, when the pressure sensor 20 is subjected to pressure, the resistance of the first pressure detection element 201 and the second pressure detection element 202 changes, and the resistance of the first pressure detection element 201 and the second pressure detection element 202 decreases, so that the voltage across the first pressure detection element 201 and the second pressure detection element 202 changes, the center voltage value between the first center voltage end 21 and the center reference voltage end 62 can be generated, and the microcontroller 3 can obtain the pressure value detected by the pressure sensor 20 according to the first center voltage value, so as to obtain the weight data.

[0032] Since the measuring device 100 is provided with at least three pressure sensors 20 in the above-mentioned embodiment, the microcontroller 3 can obtain the weight data of the to-be-tested subject by respectively acquiring the center voltage values of each pressure sensor 20 and processing by an algorithm, such as a weighted calculation or the like.

[0033] In the process of evaluating the balance ability of the subject to be measured by the measuring device 100, the host computer 4 can calculate the center of gravity data of each movement of the subject to be measured through the pressure values received by the microcontroller 3 to form the actual center of gravity trajectory of the actual movement of the subject to be measured, and obtain the balance ability evaluation data of the subject to be measured by comparing the actual center of gravity trajectory with the preset balance center of gravity trajectory of the system.

[0034] In short, in the above-mentioned embodiment, whether it is the circuit of the pressure sensor 20 part or the reference voltage circuit 6, the pressure measuring module 2 obtains the center voltage value between the first center voltage terminal 21 and the center reference voltage terminal 62 to correspondingly obtain the pressure value of the pressure sensor 20, and outputs the center voltage value to the microcontroller 3 and the host computer 4, so as to obtain the weight data of the subject to be measured by the microcontroller 3 and the center of gravity data of the subject to be measured by the host computer 4, thereby the subject can obtain the weight data and the balance ability evaluation data of the subject to be measured by the measuring device 100.

[0035] In the analysis and calculation process of the power system, a node is usually selected as a reference node, and the voltage amplitude and phase of the node are fixed. This node often has the largest power generation capacity. The center voltage value can be used as a stable reference basis for calculating and analyzing the voltage and power of other nodes in the system, making the calculation process more concise and standardized. Moreover, the center voltage value is usually located at the center of the voltage change, and it is less affected by system fluctuations and interference than other voltage values, and it is more stable. Using the center voltage value as the basis for calculation can reduce the calculation error caused by voltage fluctuations and improve the accuracy and reliability of the calculation results. Therefore, in the present embodiment, the pressure sensor 20 obtains the center voltage value between the first center voltage terminal 21 and the center reference voltage terminal 62 to correspondingly obtain the pressure value to be measured. At this time, the pressure value has high accuracy, and the measuring device 100 can obtain balance ability evaluation data and weight data of the subject to be measured with higher accuracy.

[0036] Reference can be made to Figure 2 Further, the pressure measuring module 2 further comprises at least three amplification circuits 5, each of which comprises a first input end 50, a second input end 51 and a first output end 53, the first input end 50 is electrically connected to the first center voltage terminal 21, and the second input end 51 is electrically connected to the center reference voltage terminal 62.

[0037] First of all, it needs to be understood that for some weak physical quantity changes such as temperature, pressure, displacement, etc., the electrical signal converted by the sensor is often very small. Using an amplification circuit 5 can amplify these small electrical signals so that they can be more accurately detected and measured by measuring instruments, thereby improving the accuracy and resolution of the measurement. For example, in a precise pressure measurement system, the small resistance change of the pressure-sensitive resistor caused by the change of the pressure is converted into a voltage signal, which needs to be amplified by the amplification circuit 5 before it can be accurately converted into a digital signal by the analog-to-digital converter for processing.

[0038] Therefore, in the above embodiment, an amplification circuit 5 is provided corresponding to each pressure sensor 20 to expand the center voltage signal, so that the pressure measurement module 2 can form a stronger pressure value signal, and the microcontroller 3 and the host computer 4 can more accurately receive the pressure value signal, thereby obtaining weight data and center of gravity data corresponding to the pressure value.

[0039] Reference can be made to Figure 1 Further, the pressure measurement module 2 further comprises a digital-to-analog converter 7, one end of the digital-to-analog converter 7 is electrically connected to the first output end 53, and the other end of the digital-to-analog converter 7 is electrically connected to the microcontroller 3.

[0040] It needs to be understood that the digital-to-analog converter 7 (DAC) can convert digital signals into analog signals, so that the system can process and output analog signals, realize the interaction and cooperation of digital systems and analog devices or sensors, etc., and at the same time, the digital-to-analog converter 7 can improve the signal quality and measurement accuracy. In the process of using the measuring device 100 to evaluate the balance ability of the measured object, using the digital-to-analog converter 7, the pressure measurement module 2 can more accurately feedback the signal change of its pressure value, so that the host computer 4 can obtain more accurate pressure value data, thereby improving the accuracy of the corresponding multiple center of gravity data, so that the measuring device 100 can provide more accurate balance ability evaluation data to the user.

[0041] Reference can be made to Figure 3 In some embodiments, the bearing table 1 comprises a bearing panel 10 and a base assembly 11, the bearing panel 10 can bear the measured object, the bearing panel 10 is provided with four sub-bearing areas 101, the four sub-bearing areas 101 are distributed in a matrix on the surface of the bearing panel 10, wherein when the measured object is located on the bearing panel 10, the sub-bearing area corresponds to different areas of the contact surface between the measured object and the bearing panel 10.

[0042] The base assembly 11 is connected with the bearing panel 10 and forms a receiving cavity with the bearing panel 10 to accommodate the working module in the measuring device 100. One side of the base assembly 11 is used to contact the placing plane of the measuring device 100, and the other side is used to connect the bearing panel 10 to support the bearing panel 10 on the placing plane.

[0043] The at least three pressure sensors 20 include a first pressure sensor 203, a second pressure sensor 204, a third pressure sensor 205, and a fourth pressure sensor 206, which correspond to one sub-bearing area 101 respectively. The first pressure sensor 203 and the second pressure sensor 204 are arranged along the first direction X, the first pressure sensor 203 and the third pressure sensor 205 are arranged along the second direction Y, the third pressure sensor 205 and the fourth pressure sensor 206 are arranged along the first direction X, and the fourth pressure sensor 206 and the second pressure sensor 204 are arranged along the second direction Y, so as to ensure that at least two pressure sensors 20 are arranged along the first direction X and the second direction Y.

[0044] It should be understood that the first pressure sensor 203, the second pressure sensor 204, the third pressure sensor 205, and the fourth pressure sensor 206 are all the pressure sensors 20 described above, but the positions of these pressure sensors relative to the bearing panel 10 are different. In other words, in order to facilitate the distinction, the pressure sensors 20 at different positions relative to the bearing panel 10 are renamed as the first pressure sensor 203, the second pressure sensor 204, the third pressure sensor 205, and the fourth pressure sensor 206.

[0045] The first pressure sensor 203 is used to obtain a first pressure value, the second pressure sensor 204 is used to obtain a second pressure value, the third pressure sensor 205 is used to obtain a third pressure value, and the fourth pressure sensor 206 is used to obtain a fourth pressure value. The host computer 4 is used to determine a first barycentric coordinate value along the first direction X according to the force ratio of the first pressure value to the fourth pressure value and the distance between the first pressure sensor 203 and the fourth pressure sensor 206. The host computer 4 is used to determine a first barycentric coordinate value along the second direction Y according to the force ratio of the second pressure value to the third pressure value and the distance between the second pressure sensor 204 and the third pressure sensor 205.

[0046] In an implementable manner, the first gravity center coordinate value along the first direction X is determined by the force ratio of the first pressure value to the fourth pressure value multiplied by the interval of the first pressure sensor 203 and the fourth pressure sensor 206 along the first direction X, and the second gravity center coordinate value along the second direction Y is determined by the force ratio of the second pressure value to the third pressure value multiplied by the interval of the second pressure sensor 204 and the third pressure sensor 205 along the second direction Y.

[0047] Further, the first gravity center coordinate value along the first direction X is determined by first obtaining the force ratio of the first pressure value to the fourth pressure value multiplied by the interval of the first pressure sensor 203 and the fourth pressure sensor 206 along the first direction X, and the force ratio of the second pressure value to the third pressure value multiplied by the interval of the second pressure sensor 204 and the third pressure sensor 205 along the first direction X, and then taking the average of the two intervals; the second gravity center coordinate value along the second direction Y is determined by first obtaining the force ratio of the second pressure value to the third pressure value multiplied by the interval of the second pressure sensor 204 and the third pressure sensor 205 along the second direction Y, and the force ratio of the first pressure value to the fourth pressure value multiplied by the interval of the first pressure sensor 203 and the fourth pressure sensor 206 along the second direction Y, and then taking the average of the two intervals. In this way, the accuracy of the gravity center data is further improved by weighted average.

[0048] Reference can be made to Figure 1 In some embodiments, the measuring device 100 further comprises a body fat measuring module 8, which is located in the installation cavity 110. The body fat measuring module 8 comprises two electrode sheets 80 and a control member 81. The two electrode sheets 80 are electrically connected to the control member 81, and at least partially exposed on the surface of the bearing table 1. The two electrode sheets 80 are used to form a current-carrying loop with the subject to be measured. The control member 81 is used to obtain resistance data according to the data of the current-carrying loop. The body fat measuring module 8 is electrically connected to the microcontroller 3. The microcontroller 3 is used to obtain the body fat data of the subject to be measured according to the resistance data.

[0049] The body fat measuring module 8 expands the functions of the measuring device 100, so that the measuring device 100 can simultaneously measure the body fat data of the subject to be measured. The user can obtain more comprehensive information of the subject to be measured through the measuring device 100, so as to more comprehensively evaluate the situation of the subject to be measured.

[0050] Further, the host computer 4 comprises a first Bluetooth module 40, and the microcontroller 3 comprises a second Bluetooth module 30, the first Bluetooth module 40 is in communication connection with the second Bluetooth module 30, and the second Bluetooth module 30 is configured to transmit the weight data to the first Bluetooth module 40. In this way, the host computer 4 and the measuring device 100 can be arranged separately, and the relative position between the two does not need to be limited by the actual wire. The user can move the host computer 4 flexibly, and the product use feeling of the measuring device 100 is improved.

[0051] For reference Figure 3 and Figure 4 Optionally, the bearing panel 10 is a square plate, so that when the bearing panel 10 is deformed at the center, the maximum deformation amount that can be formed by the circumference of the bearing panel 10 is the same, thereby the bearing panel 10 has stronger structural stability.

[0052] In addition, when the user needs to carry the measuring device 100 out, since the axial size of the square bearing panel 10 is the same, the user does not need to adjust the direction of the measuring device 100 excessively, and the size of the container for carrying the measuring device 100 can meet the length of any side of the bearing panel 10.

[0053] In addition, since the measuring device 100 needs to be applicable to a variety of measured objects, the measuring device 100 needs to meet the contact requirements of most measured objects, and itself needs to have certain size constraints. The square bearing panel 10 only needs to have a length that meets the minimum size requirement, which to some extent reduces the material consumption of the bearing panel 10, saves the production cost of the bearing panel 10, and further reduces the cost of the measuring device 100.

[0054] For reference Figure 3 and Figure 4 In some embodiments, the measuring device 100 further comprises an anti-skid layer 12 arranged on the surface of the bearing table 1 to increase the friction between the measured object and the bearing table 1 and increase the stability of the measured object on the surface of the bearing table 1.

[0055] Optionally, the measuring device 100 further comprises a soft package structure 13 connected to the circumferential surface of the bearing table 1, so as to reduce the edge damage of the measuring device 100 and reduce the hard contact between the measured object and the measuring device 100.

[0056] For reference Figure 1 In some embodiments, the measuring device 100 further comprises a power module 9 arranged in the mounting cavity 110 and electrically connected to the pressure measuring module 2 and the microcontroller 3 to provide the electrical energy required for the operation of the pressure measuring module 2 and the microcontroller 3.

[0057] For reference Figure 1Optionally, the host computer 4 comprises a display screen 41 for displaying weight data and / or center of gravity data for intuitive reading of at least part of the data by a user.

[0058] Optionally, the power module 9 comprises a power supply 90 and a charge management component 91, wherein the power supply 90 is capable of providing a reference voltage and an operating voltage for stable operation of the system, and the charge management component 91 is used to manage the power supply 90 and detect the operating condition of the power supply 90.
