Description

Technical Field

[0001] The present invention relates to the field of measuring instruments and methods for body dynamic capabilities, and in particular to measuring instruments and methods for measuring dynamic comprehensive basic capabilities of a person's body, such as dynamic stability, balance, agility, coordination, and relaxation. Background Art

[0002] Machines are tools for transforming the world, while instruments are tools for understanding the world, the prerequisite for transforming the world, and the driving force behind scientific research. Academician Wang Daheng, one of the pioneers of metrology research in China and recipient of the "Two Bombs and One Satellite Medal of Merit," pointed out that "instruments" are not "machines." Important criteria for evaluating instruments include sensitivity, reliability, compact size, fast response, multi-dimensional detection (dynamic), strong environmental adaptability, long life, and portability.

[0003] Currently, there are many types of instruments that can measure static physical fitness indicators and partial, single indicators of dynamic physical ability. However, there is still a lack of instruments that can measure dynamic comprehensive basic physical abilities (such as dynamic stability, dynamic balance, dynamic agility, dynamic coordination, and dynamic relaxation ability, hereinafter referred to as dynamic comprehensive basic abilities). Some of them are large in size, occupy a large area when used, are inconvenient to move, inconvenient to carry, have high manufacturing or use costs, and are subject to limited application scenarios.

[0004] For the aforementioned dynamic comprehensive basic abilities, there are some indirect manual measurement instruments or methods, such as walking with objects carried, walking with eyes closed, standing on one leg, and shuttle run tests. However, these instruments and methods have one or more deficiencies when used, such as large measurement deviations, high physical energy consumption, long time consumption, large space occupation, high reliance on manual operation or subjective judgment, and not conducive to continuous or repeated measurement. Some also have deficiencies such as many interference factors, difficulty in unifying standards, very narrow scope of application, and poor comparability. For example, in the shuttle run test, due to differences in gender, age, height, weight, running speed, physical strength, etc. of the subjects, the measurement results are still insufficient in fairness, reliability, comparability and practicality for reflecting agility ability. Moreover, after the test, the subjects need to rest for a long time before being retested or participating in subsequent tests of other items.

[0005] How to conveniently, efficiently, accurately and reliably measure the above-mentioned basic dynamic comprehensive body abilities is a technical problem that people engaged in athlete selection and training, fitness coaching, physical education teaching, physical fitness monitoring and other related work have always been eager to solve but have never been successful.

[0006] The existing electric scooter is a means of transportation, belonging to the field of machine technology. The international patent classification is Part B - Operation: Transport, B62 Trackless Land Vehicle, which does not belong to the same category as the field of instrument technology and is far away from the technical field involved in the present invention.

[0007] The inventor of the present invention has previously applied for and disclosed in China a fitness exercise device and method (application date: 2018.04.19, publication number: CN110384892A, hereinafter referred to as "Solution A"), a practice device and its use and control method (application date: 2018.12.28, publication number: CN109646927A, the product name is "Gudi Robot", also known as "Tai Chi Car", which has been put on the market for public sale, hereinafter referred to as "Solution B"), a competition device and method (application date: 2 021.04.08, CN112891902A, hereinafter referred to as “Scheme C”) and a massage device and method applied for and disclosed in China by Hangzhou Gudi Life Science Technology Co., Ltd. (Application date: 2020.07.14, Publication number: CN111643356A, hereinafter referred to as “Scheme D”) (hereinafter collectively referred to as “other fields to be transferred schemes”), which transfer electric scooter technology from B62 to A63 (sports; games; entertainment activities) technical field, which is also far from the main technical field involved in the present invention.

[0008] Existing electric scooters and the aforementioned solutions for their potential application in other fields are limited by inconsistencies in components, structures, manufacturing, usage locations, users, usage conditions, and human-computer interaction environments, making it difficult to fairly, accurately, reliably, comparable, intuitively, and practically measure the aforementioned comprehensive dynamic basic physical abilities of the measured subject. Electric scooters have been available for many years, and the aforementioned solutions for their potential application in other fields have also been publicly available for a long time. However, the existing technology has not yet been able to solve the aforementioned problem, which also demonstrates the difficulty of this technical problem. Summary of the Invention

[0009] The present invention overcomes the technical bias of the original field, purposefully and selectively changes the elements and element relationships, composition, structure, function, control, and usage methods of electric scooters and the aforementioned other fields to be converted, recombines and converts them to the technical field of body dynamic comprehensive basic ability measurement instruments and measurement methods, selects a narrow range not mentioned from the wide range disclosed in the original technology in other fields, replaces or omits the technical features and elements that the original technicians in other fields tried to maintain, and utilizes the technical features that the original technicians in other fields tried to avoid to produce unexpected technical effects, forming new uses, so as to solve the aforementioned technical problems in measuring the body dynamic comprehensive basic ability that people have always wanted to solve but have never been successful.

[0010] To achieve the above-mentioned objectives, the present invention is implemented through the following three sets of technical solutions. These three sets of technical solutions belong to the same general inventive concept, are technically interrelated, contain common specific technical features, and can be implemented in combination in the same set of measuring instruments and methods, thereby realizing multifunctional and intensive applications. In addition, the "full range" mentioned in the following description refers to the entire process of the measuring instrument from the start of movement to the stop of movement, and the "single range" refers to the single-segment process of the measuring instrument from the start of movement to automatic reversal, or from the current reversal to the next automatic reversal (in the case of continuous reciprocating movement, a full range includes many single range segments).

[0011] Technical solution 1:

[0012] A new measurement index is created to better measure the dynamic comprehensive basic ability of the subjects. This measurement index is the adaptation value of the subjects to repeated sudden disturbance impacts when standing on a smaller unstable support, referred to as "dynamic disturbance adaptation value" or "GD1".

[0013] The subject stands on a smaller unstable support, with only the soles of the feet allowed to touch the support. During the test, no other part of the body may touch any object that helps the subject stand steady. When subjected to repeated sudden disturbances and impacts, in order to prevent the body from falling off the support or falling, it is necessary to integrate and apply the body's dynamic comprehensive basic abilities such as dynamic stability, balance, agility, coordination, and relaxation. The level of these dynamic comprehensive basic abilities and their integrated application determine the extent to which the subject can withstand repeated sudden disturbances and impacts.

[0014] The challenge here lies in determining, in conjunction with specific, real-world application scenarios, what metrics can be measured to safely, conveniently, efficiently, accurately, reliably, and comparably reflect the subject's comprehensive dynamic basic abilities. Through in-depth research and extensive testing, this technical solution purposefully incorporates selective inventions, new use inventions, diversion inventions, and element-modification inventions into existing electric scooters and other previously mentioned potential applications, resulting in an instrument and method for measuring dynamic physical abilities.

[0015] This measuring instrument (hereinafter referred to as "instrument 1") includes a pedal, a motor and bridge assembly, a driven wheel and bridge assembly, a power supply assembly, a main control board assembly, a motor drive module, and a physical fitness measurement module. The motor and bridge assembly, the driven wheel and bridge assembly, the power supply assembly, the main control board assembly, and the motor drive module are respectively installed under the pedal. The power supply assembly supplies power to the main control board assembly and the motor drive module. The motor drive module is connected to the motor. The main control board assembly is connected to the motor drive module and the physical fitness measurement module. The physical fitness measurement module can accept the setting of the gear before the measurement is started to determine the one-way length limit value (the one-way length limit value is only allowed to be predetermined by setting the gear or according to the default value before the measurement is started, and cannot be changed during the measurement. It remains fixed until the measurement is terminated, and is hereinafter represented by L). When the measurement start signal is detected, the physical fitness measurement module immediately controls the output power with the preset initial output power. The instrument 1 is controlled to move in the initial direction, and the one-way timing is immediately started, the measurement termination signal is detected, and the one-way moving distance of the instrument 1 is monitored. When the one-way moving distance reaches the limit value L, the one-way time is immediately calculated and recorded, and the output power is automatically increased by one level. The instrument 1 is immediately controlled to switch the moving direction and suddenly move in the opposite direction, and a new one-way timing is immediately started, and the monitoring of the one-way moving distance is restarted. When the one-way moving distance reaches the limit value L again, the new one-way time is immediately calculated and recorded, and the minimum value (hereinafter represented by t) excluding the first and last one-way time is compared and selected from all the previous one-way time amounts, and the minimum value t is refreshed and output. The output power is gradually increased in this cycle to control the instrument 1 to perform a sudden reversal back and forth movement until the measurement termination signal is detected and the instrument 1 is immediately controlled to stop moving and the minimum value t is output.

[0016] The "sudden reversal" means that when reversal is required, the direction control end of the motor drive module is immediately reversed without waiting for the instrument to brake and stop. Due to inertia, this reversal process actually still takes a certain amount of time, but for the body's adaptability, this already seems "sudden".

[0017] Furthermore, the instrument 1 preferably also includes a position monitoring component, which is connected to the main control board component. It acts as a safety lock before the measurement is started to limit whether the measurement is allowed to be started. During the measurement process, it continuously monitors whether the subject standing on the pedal is offside, falls or falls. Once the subject is found to be offside, falls or falls, a position abnormality signal is immediately sent to the physical fitness measurement module via the main control board component. The physical fitness measurement module then processes the position abnormality signal as a measurement termination signal. Only one discrete sensor element is used and only one switch signal is transmitted to simultaneously monitor four abnormalities of absence, offside, falling and falling.

[0018] Furthermore, the value range of the one-way length limit value L is preferably 0.1 to 0.6 meters; when comparing the minimum values ​​of all previous one-way times, the one-way times that suddenly change beyond the range are preferably regarded as invalid values ​​and eliminated.

[0019] Furthermore, the fitness measurement module of the apparatus 1 includes a "unilateral strong perturbation" option switch, which is selected before the measurement is started to control whether the perturbation is strengthened only during the forward or return journey. Selecting the perturbation only during the forward or return journey before the measurement is started allows the subject's motion adaptation values ​​to be measured on each side, such as the left, right, front, and back, based on their standing orientation.

[0020] Furthermore, the instrument 1 also includes a wireless communication module, which is connected to the main control board assembly and is used for wireless communication with external devices, sending and receiving instructions for setting gears, setting unilateral interference, starting measurement, terminating measurement (emergency stop), acceleration, reversing instructions, and one-way time data, etc. When the instrument 1 receives an acceleration instruction during the measurement process, it will increase the output power accordingly to speed up the measurement progress. When it receives a reversing instruction, it will abandon the current one-way timing, switch the moving direction suddenly to the opposite direction, and immediately start a new one-way timing and restart monitoring the one-way moving distance. This can avoid deviation from the site due to accumulated sideslip.

[0021] A method for measuring body dynamic ability (hereinafter referred to as "method 1") uses the aforementioned instrument 1 to measure the dynamic comprehensive basic ability of the subject: after ensuring the safety of the surrounding environment, the power of the instrument 1 is turned on, the gear of the instrument 1 is set to determine the one-way length limit value L, the subject wears protective equipment and stands on the pedal of the instrument 1, and sends a measurement start signal to the instrument 1. When the instrument 1 detects the measurement start signal, it immediately moves in the initial direction with a preset initial output power, and immediately starts one-way timing, listens for the measurement end signal, and starts monitoring the one-way moving distance of the instrument 1. When the one-way moving distance reaches the limit value L, the one-way time is immediately calculated and recorded, and the output power is automatically increased by one level, and the control The instrument 1 is controlled to switch its moving direction suddenly to the opposite direction, and immediately start a new one-way timing and restart monitoring the one-way moving distance. When the one-way moving distance reaches the limit value L again, the new one-way time is immediately calculated and recorded, and the minimum value t excluding the first and last one-way time is compared and selected from all the previous one-way time, and the minimum value t is refreshed and output. In this cycle, the output power is gradually increased to control the instrument 1 to perform a sudden reversal of movement until the measurement termination signal is detected, and the instrument 1 is immediately controlled to stop moving and output the minimum value t - this value is recorded as the subject's disturbance adaptation value GD1. The measurement is now completed, and a new measurement is prepared or the power of the instrument 1 is turned off and put back in place.

[0022] In actual application scenarios, the instrument 1 only rolls on the ground by the flexibly rotating wheels. The bridge connecting the wheels is elastic and can be twisted flexibly. The bridge is then connected to the elastic pedals. As a whole, a small and unstable support body with a certain height from the ground is formed for the subject standing on the pedals. During the measurement, the instrument 1 automatically changes direction frequently and suddenly within a very short stroke, and accelerates back and forth step by step, making this human-computer interaction an open and complex giant system. The superposition, multiplication and coordination of comprehensive factors can easily cause the subject to shake and tremble left and right, front and back, and then various parts of the body involuntarily tense and twist, and are forced to go offside or fall.

[0023] This technical solution is not obvious to those skilled in the art, and other fields of technology as a whole do not provide technical inspiration for solving the technical problem through this technical solution. The existing electric scooters and the aforementioned solutions to be converted from other fields are far away from the main technical field of the present invention. The technical problems to be solved, technical effects, functions, uses, application scenarios, precautions, etc. are very different. There is a huge difference between different fields. Therefore, as a whole, there is no technical inspiration for solving the technical problem through this technical solution. Not only does it not provide corresponding technical inspiration, but the distinguishing features of this technical solution compared with them violate their original design intent and use and weaken their technical effects. The original technical personnel in the field have no motivation and willingness to make such changes. For example: 1. Existing electric scooters are primarily used as a means of transportation for long, one-way travel. Even if they have a reverse function, they must first brake to a complete stop before reversing. They automatically and suddenly change direction frequently within a very short distance and increase output power (acceleration) without an upper limit. This not only defeats their purpose but also significantly increases safety risks.

[0024] 2. Compared with the aforementioned solutions to be transferred from other fields, the overall distinguishing features of this technical solution include but are not limited to: Before the measurement starts, the gear is set to determine the one-way length limit value L. This value is only allowed to be determined by setting the gear before the measurement starts or by default. It cannot be changed during the measurement and remains fixed until the measurement ends. The output power is increased (accelerated) without an upper limit. The one-way time is calculated and the minimum valid value among all the one-way times is compared and output. The first, last and mid-way sudden changes in the one-way time range are regarded as invalid values ​​and eliminated (referred to as "cutting off the head + tail + filtering"). The station monitoring component and its use of only a discrete sensor element and only transmitting a switch signal can simultaneously monitor four anomalies: absence, offside, falling and falling (referred to as "one monitor four"), unilateral interference, and the limited one-way length value range is narrower (preferably 0.1 to 0.6 meters), etc. Further examples are given: (1) The one-way length limit value L in this technical solution cannot be changed during the measurement process, which is conducive to ensuring the practicality and comparability of the measurement results. The one-way time measured when the one-way length fluctuates is not practical. The characteristics of the field of measuring instruments determine that standard unification is convenient for guiding practical applications. The actual application scenario of the present invention determines that the comparability requirements for measurement results are much higher than those in other fields mentioned above. It requires that the one-way time values ​​of all previous measurements during the measurement process be comparable with each other, that multiple measurements of the same subject be longitudinally comparable, and that cross-domain comparability be achieved for measurements of different populations across regions, countries, races, etc.

[0025] (2) The body has a memory effect, and exercise has a trace effect. In the other aforementioned fields, even when it comes to the one-way length, it should not be fixed during use, otherwise its technical effect will be significantly reduced and its purpose will be violated. In other words, allowing the user to change the distance during use is a necessary function, and automatic random distance change or even random speed change is a preferred function. Some of them also explicitly include timed round trips. Due to differences in ground conditions, load weight, operating speed, dynamic performance of components, etc., the one-way length is inevitably uncertain and there are obvious fluctuations.

[0026] ⑶ Automatically increasing the output power (acceleration) without an upper limit is a clear violation of the design purpose of the aforementioned solutions to be converted in other fields, and will also increase its safety risks in use; the application scenarios involved in this technical solution are special. The measurement environment related to sports movements usually has multi-level and multi-faceted security guarantees to prevent irrelevant people and objects from accidentally entering the measurement site. There are also dedicated personnel responsible for protecting the subjects and supervising that the subjects must wear protective equipment. The technical solution also has special designs for safety of use, so safety and health will be more highly protected.

[0027] (4) In the other aforementioned fields, a short single-stroke distance will seriously raise the threshold for users to try, thereby hindering the realization of the main technical purposes and uses such as fitness exercises, practice or massage. In this technical solution, a too short single-stroke distance will also raise the application threshold and reduce the intuitiveness of the measurement results, but a long single-stroke distance will reduce the intensity of the disturbance during measurement, significantly increasing the measurement time and cost. The standing human body is not a "rigid body" in the mechanical concept. There are great differences in human bodies of different genders, ages, heights, weights, and physiques. In actual applications, the performance of some components varies greatly. When running at high speed with heavy loads and frequent commutation, the battery voltage and current vary greatly. There will also be wheel slippage, flexible pedal shaking, and extremely complex human-computer interaction. These complex factors combined together result in the appropriate value range of the single-stroke length in this technical solution not being known, analyzed, or inferred by existing technology, and there is no prior data for reference. It requires a lot of creative labor to research and experiment to obtain it.

[0028] ⑸ Among the aforementioned schemes to be converted into other fields, even if some of them mention "massage timing", "practice timing", "practice duration", "predetermined training time", "running speed" or "speed level", the objects, methods and uses of their calculations are essentially different from the objects, methods and uses measured by the present invention. They calculate or output the total duration of the entire process, the average speed of the entire process, the instantaneous speed or actually just the speed regulation level. These indicators are more suitable for their original purposes as a whole. However, due to the fluctuations in battery voltage and current in actual application scenarios and the comprehensive differences in open complex giant systems such as load weight, ground conditions, start-stop reversing, and human-computer interaction, they cannot be simply equated with the core key indicators measured by the present invention (determining the one-way time under the one-way length benchmark, especially the effective minimum value of all previous one-way time) or obtained through simple calculation and conversion. Moreover, the original purposes of the relevant schemes also determine that there is no need to measure and compare all previous one-way time separately.

[0029] ⑹ The other fields mentioned above do not involve or require screening of effective values, monitoring absence (safety lock), monitoring offside, and unilateral interference, nor can they provide the technical inspiration of "cutting off the head + removing the tail + filtering" and "one monitor four": the first single trip starting from a stationary state is different from the subsequent single trip starting from a moving state with a sudden change of direction. The object to be measured may have become unstable at the last time, and there are uncontrollable factors such as wheel slippage and pedal tilting in the middle, causing "measurement noise" interference; monitoring absence (safety lock) can provide an additional layer of safety for automatically increasing output power (acceleration) without an upper limit; monitoring offside is to improve the comparability of multiple levels of measurement; unilateral interference facilitates investigation, analysis and comparison in more dimensions.

[0030] ⑺The above-mentioned distinguishing features need to be creatively studied and tested in combination with actual application scenarios. They support each other functionally and have an interactive relationship. Considering the whole, the technical effects to be achieved are not originally needed or expected in the aforementioned other fields, and even if they can be known, they are mostly what we want to avoid in the original application scenarios.

[0031] Technical solution 2:

[0032] A new measurement indicator is created to better measure the subject's ability to integrate and apply the above-mentioned dynamic comprehensive basic abilities to dynamically control disturbances. This measurement indicator is the integrated ability value of the subject standing on a smaller unstable support body, enduring repeated disturbance impacts, and being able to cleverly use the disturbance impacts to move the support body to the target position, referred to as "control skill value" or "GD2".

[0033] The test subject stands on a smaller unstable support, with only the soles of the feet allowed to touch the support. During the test, no other part of the body may touch any objects that help to stabilize the body. In order to maintain the body from falling off the support or falling when subjected to repeated disturbance impacts, the subject must be able to cleverly use the disturbance impact to move the support to the target position. This requires not only the integration and application of the aforementioned basic dynamic comprehensive capabilities, but also the ability to fully mobilize the body to leverage force, follow the trend and shake to generate overall strength (which is related to the concept of "core strength" in kinematics, and a more advanced level is reflected in the "whole strength" in Chinese martial arts terminology) to achieve the effect of "four ounces to move a great weight".

[0034] It is difficult to directly measure the overall strength in an open, complex system like the human body. How to automatically and digitally measure people's martial arts skills is an unresolved problem. This technical solution creatively uses the time required for the subject to move the unstable support body to the target position as an indirect measurement indicator. After in-depth research and a large number of experiments, the aforementioned other field plan C is purposefully selected for invention, new use invention, conversion invention and element change and omission invention, creating another body dynamic ability measurement instrument and measurement method.

[0035] This measuring instrument (hereinafter referred to as "Instrument 2") includes a pedal, a motor and bridge assembly, a driven wheel and bridge assembly, a power supply assembly, a main control board assembly, a motor drive module, a wireless communication module, a line-reaching monitoring assembly, and a dynamic measurement module. The motor and bridge assembly, the driven wheel and bridge assembly, the power supply assembly, the main control board assembly, and the motor drive module are respectively installed under the pedal. The power supply assembly supplies power to the main control board assembly and the motor drive module. The motor drive module is connected to the motor. The main control board assembly is connected to the motor drive module, the wireless communication module, the line-reaching monitoring assembly, and the dynamic measurement module. When the line-reaching monitoring assembly monitors the line-reaching identification line, it immediately sends a line-reaching signal to the dynamic measurement module. The dynamic measurement module can accept the setting of the gear before the measurement is started to determine the one-way length limit value (the one-way length limit value is only allowed to be predetermined by setting the gear or according to the default value before the measurement is started. , cannot be changed during the measurement process, remains fixed until the measurement is terminated, hereinafter represented by L), the driving measurement module immediately starts timing when it detects the measurement start signal, controls the instrument 2 to move in the initial direction with a preset initial output power, listens for the line arrival signal, listens for the measurement termination signal, and monitors the one-way movement distance of the instrument 2. When the one-way movement distance reaches the one-way length limit, it immediately controls the instrument 2 to reverse and move in the opposite direction and restarts monitoring the one-way movement distance. The instrument 2 is controlled to move back and forth in this cycle and does not accept remote control reversing instructions during the measurement period. When the line arrival signal is detected, the timing is immediately ended, the instrument 2 is controlled to stop moving, and the timing result (i.e., the total time from the start of the measurement to the end of the measurement) is output, or when the measurement termination signal is detected, the instrument 2 is immediately controlled to stop moving and the timing value is canceled, and this measurement is invalid.

[0036] Furthermore, the instrument 2 preferably also includes a position monitoring component, which is connected to the main control board component. It acts as a safety lock before the measurement is started to limit whether the measurement is allowed to be started. During the measurement process, it continuously monitors whether the subject standing on the pedal is offside, drops or falls. Once the subject is found to be offside, drops or falls, a position abnormality signal is immediately sent to the control measurement module via the main control board component. The control measurement module then processes the position abnormality signal as a measurement termination signal. Only one discrete sensor element is used and only one switch signal is transmitted to simultaneously monitor four abnormalities of absence, offside, dropping and falling.

[0037] Furthermore, the value range of the one-way length limit value L is preferably 0.1 to 0.6 meters.

[0038] Another method for measuring dynamic physical ability (hereinafter referred to as "Method 2") uses the instrument 2 to measure the dynamic comprehensive basic ability of the subject: arrange the reach line marking line at the measurement site according to the measurement specifications, ensure the safety of the surrounding environment, and then turn on the power of the instrument 2. The gear can be set to determine the one-way length limit value L. The subject wears protective equipment and stands on the pedal of the instrument 2 and ensures that the instrument 2 is at the measurement starting point. A measurement start signal is sent to the instrument 2. When the instrument 2 detects the measurement start signal, it immediately starts timing, moves in the initial direction with a preset initial output power, listens for the reach line signal, listens for the measurement termination signal, and monitors the one-way moving distance. When the one-way moving distance reaches the limit value L, it immediately stops. That is, it changes direction and moves in the opposite direction and starts monitoring the one-way moving distance again, and moves back and forth in this cycle and does not accept remote control reversing commands during the measurement. The subject maintains himself / herself from falling off the pedal and forcibly pushes the pedal with the sole of the foot to force the instrument 2 to offset and move to the reach line identification line. The instrument 2 immediately ends the timing, stops moving, and outputs the timing result (that is, the total time used from the start of the measurement to the end of the measurement) when it detects the reach line signal - this value is recorded as the subject's said driving effort value GD2, or immediately stops moving and cancels the timing value when it detects the measurement termination signal, and this measurement is invalid. The measurement ends after outputting the timing result or canceling the timing value, and prepares for a new measurement or turns off the power of the instrument 2 and puts it back in place.

[0039] Furthermore, the instrument 2 can preferably also monitor a speed regulation signal during measurement, and adjust the output power of the instrument 2 accordingly when the speed regulation signal is monitored.

[0040] Furthermore, the instrument 2 preferably also includes a limit value for the number of times the line is reached (the value range is a positive integer ≥1, hereinafter represented by N) that can be set before the measurement is started, so as to support automatic measurement along a broken line trajectory and ≥1 shuttle trips. The automatic measurement module counts the detected line-reaching signals, and when the count reaches the limit value N, it is deemed that the line is finally reached.

[0041] Furthermore, the method 2 preferably also includes sending a speed control signal to the instrument 2 via a remote control device during measurement.

[0042] Furthermore, the method 2 preferably also includes setting a limit value N for the number of times the line is reached before the measurement is started, and also includes only needing to preset two line-reaching identification lines to combine with setting the limit value N for the number of times the line is reached to achieve automatic shuttle measurement supporting ≥1 trips. This "shuttle" does not refer to the "back and forth movement" of the instrument 2, but is relative to the line-reaching identification line. For example: if the line-reaching identification line A is arranged at the starting point of the measurement and the line-reaching identification line B is arranged at another place, then from A to B and then back to A is regarded as one shuttle trip (assuming the limit value N is 2), and then from A to B and back to A is regarded as two shuttle trips (assuming the limit value N is 4), and so on, multiple shuttle trips can be automatically measured (assuming the limit value N is twice the number of shuttle trips).

[0043] It can support the shuttle measurement, which can not only realize longer-range measurement in a smaller venue, but also help measure the subject's two-way control skill value GD2, because most people's control ability in different directions is not balanced. Supporting separate measurement of each unidirectional and two-way measurement is conducive to grasping more comprehensive indicators.

[0044] This technical solution is not obvious to those skilled in the art, and other technical fields as a whole do not provide technical inspiration for solving the technical problem through this technical solution. Similar reasons cited in the description of the aforementioned technical solution 1 also apply to this technical solution 2 and will not be repeated here. Only two points will be added to the adopted other field solution C: 1. The important uses of Plan C include testing the coordination and quick reaction ability of the hands, eyes, and brain. When the competition device retreats, issuing a command to move forward again through a button or remote control (collectively referred to as "remote control reversing") is an essential function. It is also preferably equipped with a multi-person collaborative remote control module and a remote operation module. Therefore, technicians in the original field have no motivation or willingness to abandon the essential remote control reversing.

[0045] 2. The backward displacement of Scheme C varies during operation, depending on when the competitor remotely switches direction. It's already difficult for people to maintain steady footing on such an unstable device, and the challenge becomes even greater when repeatedly disturbed. Technicians in the field generally believe that without remote control switching, it's impossible to move a device that moves a predetermined, equal, one-way distance back and forth from the starting point to the end of the track. Furthermore, most people find it difficult to move such a bidirectional, symmetrical, short-distance device a significant distance simply by standing on it. This has led people to dismiss the possibility of remote control switching, hindering research and development into measuring the dynamic kung fu described in this invention.

[0046] However, as previously mentioned in the description of Technical Solution 1, the complex, open, and large-scale human-computer interaction system in the present invention's application scenario requires a simplified derivation based solely on the mechanical concept of a "rigid body," which is insufficient and inaccurate. Some subjects, after extensive and deliberate practice, can achieve what is generally considered impossible. Our painstaking research and testing have confirmed that some individuals can move the device 2 to a target location over a considerable distance simply by shaking and bouncing their bodies, without requiring a remote control to steer the device.

[0047] This technical solution overcomes the aforementioned technical bias and adopts technical means that people have abandoned due to technical bias. It omits the remote control reversing function of Solution C and also fixes the one-way length in advance before the measurement starts, solving technical problems that the original technical personnel in the field could not have anticipated, and achieving technical effects that the original technical personnel in the field could not have anticipated.

[0048] After overcoming technical bias and making creative improvements, the aforementioned Technical Solutions 1 and 2 are already practical enough for the vast majority of subjects. In addition, some subjects will expect more difficult challenges after their basic dynamic comprehensive abilities are improved. To further meet the needs of high-level subjects, the instrument can be equipped with more powerful and more powerful batteries and motors. The only drawback is that this will increase production costs, and there is a limit to the improvement of the instrument's electric performance.

[0049] Therefore, the upper surfaces of the pedals of apparatuses 1 and 2 preferably also include numerous raised points (tenderness components) that induce tenderness on the soles of the subject's feet, thereby increasing the difficulty of standing on them without shoes. These numerous raised points further elevate the subject's standing height from the ground and utilize the subject's own weight to induce significant tenderness on the soles of their feet. Combined with the complex factors of unstable support over a small area and repeated disturbances and impacts, this creates a significant synergistic effect and stimulation, correspondingly increasing the requirements for the subject's basic dynamic comprehensive ability.

[0050] Furthermore, the instrument 1 and the instrument 2 may also preferably include a display component, an audio playback module and a speaker. The display component and the audio playback module are connected to the main control board component, and the audio playback module is connected to the speaker. The display component is used to interactively display gear settings, limit value settings, operating status, measurement results, etc., and the audio playback module is used to play voice prompts, measurement results, background music, etc.

[0051] Furthermore, the measurement result output by the instrument 1 (the minimum effective value of all previous one-way time measurements) and the measurement result output by the instrument 1 (the total time taken from the start of measurement to the end of measurement) can preferably be displayed on the instrument through the display component, and can also be sent to other receiving devices (such as smart phones, computers, etc.) through its wireless communication module, so as to achieve automated and digital system integration.

[0052] Technical solution 3:

[0053] A multifunctional portable body dynamic ability measuring instrument (hereinafter referred to as "Instrument 3") includes a pedal motor and bridge assembly, a driven wheel and bridge assembly, a power supply assembly, a main control board assembly, a motor drive module, and a wireless communication module. The motor and bridge assembly, the driven wheel and bridge assembly, the power supply assembly, the main control board assembly, and the motor drive module are respectively installed under the pedal. The power supply assembly supplies power to the main control board assembly and the motor drive module. The motor drive module is connected to the motor. The main control board assembly is connected to the motor drive module and the wireless communication module. It also includes a standing position monitoring assembly, a line reaching monitoring assembly, a physical fitness measurement module, a driving measurement module, and a practice module connected to the main control board assembly. The integrated operating modes that can be selected and switched by the user include a physical fitness measurement mode, a driving measurement mode The three operating modes correspond to the technical solutions of the instrument 1, the instrument 2 and the aforementioned solution B respectively. The position monitoring component acts as a safety lock before startup to limit whether startup is allowed. During the measurement / practice process, it continuously monitors whether the user standing on the pedal is offside, falling or falling. Once the user is found to be offside, falling or falling, a position abnormality signal is immediately sent to one of the physical measurement module, driving measurement module and practice module corresponding to the current operating mode via the main control board component. The module corresponding to the current operating mode then processes the position abnormality signal as a physical measurement termination, driving measurement termination or practice termination signal respectively. Only one discrete sensor element is used and only one switch signal is transmitted to simultaneously monitor four abnormalities of absence, offside, falling and falling.

[0054] Furthermore, the instrument 3 may preferably also include an audio playback module, a speaker, a display component, a tenderness component, a competition module, and a massage module. The tenderness component is installed or integrated above the pedal, the audio playback module, the display component, the competition module, and the massage module are connected to the main control board component, and the audio playback module is connected to the speaker. When the position monitoring component finds that the user's position is abnormal, it immediately sends a position abnormality signal to the competition module and the massage module via the main control board component. The integrated operating mode also includes a competition mode and a massage mode - corresponding to the technical solutions of the aforementioned scheme C and scheme D respectively.

[0055] The beneficial effects of the present invention are: It overcomes the technical bias in the original field, purposefully and selectively changes the elements and element relationships, composition, structure, function, control, and usage methods of technical solutions in other fields, recombines and repurposes them, and uses technical features that original technical personnel in other fields have tried to avoid to produce unexpected technical effects and form new uses. It creates three sets of body dynamic ability measurement instruments and measurement methods, which can conveniently and efficiently measure the body's dynamic comprehensive basic abilities such as dynamic stability, balance, sensitivity, coordination, and relaxation. In particular, it can specifically measure the disturbance adaptation value and the control skill value, and effectively solve a technical problem in the measurement of the body's dynamic comprehensive basic abilities that people in the fields of athlete selection and training, fitness coaches, physical education, physical fitness monitoring, etc. have always been eager to solve but have never succeeded. It can also be promoted and applied to the fields of enrollment selection, recruitment selection, human resources management, medical physical examinations, martial arts research and training, and it also realizes the multi-functional combination of training, maintenance, competition, and testing, which is conducive to helping more people exercise efficiently, enhance their physical fitness, and improve their abilities. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] Figure 1 This is a simplified diagram of the measuring instrument 1 embodiment of the present invention Figure 2 This is a simplified flow chart of an embodiment of the measurement method 1 of the present invention Figure 3 This is a simplified flow chart of embodiment 2 of the measurement method of the present invention Figure 4 Schematic diagram of the measuring instrument 3 embodiment of the present invention DETAILED DESCRIPTION

[0057] Technical solution 1 embodiment: The embodiment of the measuring instrument 1 is converted to the embodiment of the competitive device of the aforementioned scheme C, Figure 1 The simplified structure diagram is also from the attachment of Plan C. Figure 1 Based on the specific implementation of scheme C, this embodiment adds a physical fitness measurement module and a standing position monitoring component.

[0058] In this embodiment, the position monitoring component is a preferred option and is not required to be added. If the position monitoring component is not added, the measurement is recorded manually, and the subject's position is observed and judged to be normal before the measurement is started. The instrument is allowed to start only when the position is normal. During the measurement, the current minimum value of the refresh output of the instrument is continuously observed and remembered. When an abnormal position of the subject is observed, a termination signal of the measurement is immediately sent to the instrument. A relatively simple termination measurement method is to turn off the power of the instrument and use the minimum value measured before the subject's position abnormality occurs as the measurement result.

[0059] Standing position monitoring component: It consists of a universal reed switch (also known as "reed switch" or "magnetron") 10 with an iron sheet adhered to it and a movable magnetic key 11. The magnetic key 11 is composed of a universal magnet connected to an elastic wire with two exposed ends. The reed switch 10 is embedded in the center of the left and right sides of the instrument pedal. The reed switch 10 is connected to the main control board component, one end of which is grounded and the other end is connected to an input port of the microprocessor described in Solution C. This port inputs a low level when the magnetic key 11 is adsorbed above the reed switch 10, and inputs a high level when the magnetic key 11 is not adsorbed. It is used to transmit a standing position abnormality signal to the physical fitness measurement module. In order to facilitate the observation of whether the magnetic key 11 is successfully adsorbed in the correct position, a universal light-emitting diode component can also be embedded near the reed switch 10 to indicate the on / off state of the reed switch 10.

[0060] Safety Lock: The instrument can be factory-defaulted to "key verification start"—that is, it will only be allowed to start when the magnetic key 11 is properly attached to the reed switch 10 (at the attachment position). Alternatively, a "key verification start" option switch can be provided in the instrument, allowing the user to determine whether "key verification start" is required during use. If the instrument is configured for "key verification start," upon receiving the measurement start signal and before starting, it first checks the level of the position monitoring input port of the microprocessor. If the magnetic key 11 is not properly attached (in this embodiment, it is at a high level), the instrument will refuse to start.

[0061] "One monitor, four features": Before starting the measurement, attach the magnetic key 11 to the top of the reed switch 10 (at the attached position). Tie or tape the exposed ends of the elastic cord of the magnetic key 11 to the test subject's feet. The cord is long enough to prevent the key 11 from being pulled out of the attached position when the test subject is standing normally, but will be pulled out of the attached position if the test subject is offside, drops, or falls. Offside can include raising the foot too high or spacing the feet too far apart. The elastic cord can be a common material like a thin rubber band, with a sufficient elasticity to allow the magnetic key 11 to be easily pulled away without tripping the test subject. Because the reed switch, magnet, and rubber band are all common, it is possible to simultaneously monitor four anomalies—absence, offside, dropping, and falling—at a very low cost using only a single discrete sensor element (the reed switch) and transmitting a single switch signal.

[0062] Physical fitness measurement module: It can be implemented using the microprocessor and peripheral interface of the aforementioned technical solution C plus embedded software. The microprocessor is connected to the main control board component and is connected to the reed switch 10 and the motor drive module through the main control board component. The corresponding output port of the microprocessor is connected and sends the motor rotation direction and motor rotation power control signals to the motor drive module. The corresponding input port is connected and respectively collects the setting gear signal, measurement start signal, measurement termination signal (including standing position abnormality signal), motor rotation signal, etc.

[0063] The output power level of the instrument can be controlled by connecting the digital output port of the microprocessor that supports PWM to the speed control port of the motor drive module. For example, 8-bit PWM can achieve 0-255 level control.

[0064] The motor rotation signal can follow the scheme C and preferably connect the motor Hall line to monitor the motor rotation signal. The number of collected Hall pulse signals can be converted and compared to see whether the one-way moving distance has reached the limit value L. This can be obtained based on the diameter, pole pair number, and phase number in the motor parameters. For example, for a three-phase hub motor with a diameter of 73mm and a pole pair number of 10, each pulse represents that the distance the motor rotates is 73mm×π / (10 pairs of poles×3 phases). If the one-way length limit value L is set to 10cm, it is approximately equivalent to experiencing 13 pulses. That is, when the microprocessor collects 13 Hall pulses through the motor drive module, it can be determined that the cumulative moving distance of the instrument has reached 10cm.

[0065] The embedded software control can set the "unilateral strong disturbance" option switch before the measurement is started (according to the predefined interface signal or communication protocol, the disturbance is strengthened only in the forward journey or only in the return journey, so as to measure the disturbance adaptation values ​​of the left, right, front and back sides of the subject respectively in combination with the subject's standing direction), and can accept the setting gear to determine the one-way length limit value L (the value range is preferably 0.1 to 0.6 meters, which can be set according to the predefined interface signal or communication protocol, for example, gears 1, 2, 3, 4, 5, and 6 correspond to the limit values ​​L of 10, 20, 30, 40, 50, and 6 respectively. 60cm, which is only allowed to be determined by setting the gear before the measurement is started or by default, cannot be changed during the measurement, and remains fixed until the measurement is terminated). When the measurement start signal is detected, if the instrument is configured as "key verification start" and the magnetic key 11 is not in the adsorption position, it will refuse to start. Otherwise, it will immediately control the instrument 1 to move in the initial direction (in this embodiment, the initial voltage can be output to the rotation power control terminal of the motor drive module through the output port of the microprocessor) with a preset initial output power (in this embodiment, the initial voltage can be output to the rotation direction control terminal of the motor drive module through the output port of the microprocessor). Output the initial level), and immediately start one-way timing, listen for the measurement termination signal (including the abnormal position signal), monitor the one-way moving distance of the instrument 1, and when the one-way moving distance reaches the limit value L, immediately calculate and record the one-way time, and determine whether to automatically increase the output power by one level according to the "one-side strong interference" option (for example, when the "one-side strong interference" option switch is set to "forward strong interference", the output power will be automatically increased by one level based on the previous forward output power, and the initial output power will be automatically set back to the initial output power when returning, and so on), and immediately control the instrument 1 to switch the moving direction and move suddenly in the opposite direction The device 1 starts to move, and immediately starts a new one-way timing and restarts monitoring the one-way moving distance. When the one-way moving distance reaches the limit value L again, the new one-way time is immediately calculated and recorded, the one-way time of all previous times is compared and selected (the first, last and midway sudden changes that exceed the range are regarded as invalid values ​​and eliminated), and the effective minimum value is refreshed and output. The output power is gradually increased in this cycle to control the instrument 1 to frequently perform sudden reversal of movement until the measurement termination signal (including the abnormal position signal) is detected, and the instrument 1 is immediately controlled to stop moving, and the effective minimum value t of all previous one-way time is output.

[0066] Furthermore, the instrument 1 can also be equipped with a wireless communication module, which is connected to the main control board assembly and is used for wireless communication with external devices to send and receive instructions for setting gears, setting unilateral interference, starting measurements, terminating measurements (emergency stop), acceleration, reversing instructions, and previous one-way time data, etc. The embedded software control increases the output power accordingly when an acceleration instruction is received during the measurement process, thereby speeding up the measurement progress. When a reversing instruction is received, the current one-way timing is abandoned, the moving direction is switched suddenly to the opposite direction, and a new one-way timing is immediately started, and the monitoring of the one-way moving distance is restarted.

[0067] The "key verification start" option switch, "one-sided interference" option switch, and gear position can input signals to the microprocessor by adding a gear adjustment knob switch. If a wireless communication module is added, it is preferably implemented through a remote control device (also including applications in smartphones, computers and their application software, etc.), and the embedded software decodes the corresponding specific options and gear positions according to a pre-defined communication protocol.

[0068] Furthermore, the instrument 1 can preferably also integrate a plurality of raised points on the upper surface of the pedal that can cause tenderness to the sole of the subject's foot or add a finger pressure plate as a tenderness component, and can also be equipped with a display component, an audio playback module and a speaker. The display component and the audio playback module are connected to the main control board component, and the audio playback module is connected to the speaker. The embedded software controls the display component for interactively displaying gear settings, limit value settings, operating status, measurement results, etc., and controls the audio playback module for playing voice prompts, measurement results and background music, etc.

[0069] The simplified flow chart of the embodiment of measurement method 1 is as shown in the attached figure. Figure 2 As shown, the dynamic comprehensive basic ability of the subject is measured using the measuring instrument 1 embodiment. After ensuring the safety of the surrounding environment, the instrument 1 is powered on, including the following steps: Step 1: Set the gear of the instrument 1 to determine the one-way length limit value L, and set the "unilateral strong interference" option switch as needed (to measure the disturbance adaptation values ​​of the subject's left, right, front, and back sides, etc., based on the subject's standing position). The subject wears protective equipment and stands on the pedal of the instrument 1. For those who need to monitor their standing position, place the magnetic key 11 on the magnetic reed switch 10 with an iron block attached (at the adsorption position), and tie or tape the two exposed ends of the elastic wire of the magnetic key 11 to the subject's feet. The length of the elastic wire is sufficient to prevent the magnetic key 11 from being pulled out of the adsorption position when the subject's standing position is normal, and to prevent the magnetic key 11 from being pulled out of the adsorption position if the subject is offside, falls, or trips. Offside can include raising the foot too high or the distance between the feet is too large. Step 2: Sending a measurement start signal to the instrument 1; Step 3: When the instrument 1 detects the measurement start signal, if the instrument is configured as "key verification start" and the magnetic key 11 is not in the adsorption position, it refuses to continue. Otherwise, it immediately starts to move in the initial direction at the preset initial output power and immediately starts step 4; Step 4: one-way timing, listening for measurement termination signals (including abnormal position signals - i.e., the subject is offside, falls, or falls), and monitoring the one-way movement distance of the instrument 1; comparing and judging whether the one-way movement distance reaches the limit value L, when the one-way movement distance reaches the limit value L, immediately jump to step 5; when the measurement termination signal is detected, immediately jump to step 6; accelerate when an acceleration command is detected; and reverse when a reversal command is detected; Step 5: Calculate and record the one-way time of this trip, compare the one-way time of all the previous trips (the first, last and mid-trip sudden changes that exceed the range are considered invalid and eliminated), refresh and output the minimum valid value, determine whether to automatically increase the output power by one level according to the "unilateral interference" option, control the instrument 1 to switch the moving direction suddenly to the opposite direction, reset the one-way timer to 0, reset the one-way moving distance counter to 0, and return to step 4; Step 6: Control the instrument 1 to stop moving and output the effective minimum value t of all the one-way time measurements - this value is recorded as the subject's disturbance adaptation value GD1. The measurement is now completed, and a new measurement is prepared or the instrument 1 is turned off and put back in place.

[0070] Technical solution 2 embodiment:

[0071] The embodiment of the measuring instrument 2 is based on the aforementioned embodiment of the instrument 1, with the physical fitness measurement module replaced by the driving measurement module, and an arrival monitoring component added.

[0072] Reach line monitoring component: An infrared diffuse reflection sensor can be embedded in the bottom of the protective cover 7. The infrared diffuse reflection sensor is connected to an input port of the microprocessor via the main control board assembly, and the infrared transmitting head and the receiving head are exposed downward. When monitoring the reach line identification line, the reach line signal is automatically sent to the microprocessor via the main control board assembly; the reach line identification line can be made of black matte single-sided tape, which is flatly attached to the surface of the measurement end point before the measurement begins. The reflection distance of the infrared diffuse reflection sensor is pre-adjusted according to the height from the ground so that it can convert and output the sensor signal when the instrument is above the reach line identification line - as the reach line signal; an LED light strip can also be attached to the edge of the pedal 1 and connected to the main control board assembly to indicate the reach line status.

[0073] Dynamic measurement module: It is implemented using the microprocessor and peripheral interface of the embodiment of instrument 1 plus embedded software. The microprocessor is connected to the line monitoring component, the station monitoring component, and the motor drive module via the main control board component. The corresponding output port of the microprocessor is connected and sends the motor rotation direction and motor rotation power control signals to the motor drive module. The corresponding input port is connected and respectively collects the setting gear signal, measurement start signal, line arrival signal, measurement termination signal (including station abnormality signal), motor rotation signal, etc.

[0074] When the embedded software controls the measurement start signal, if the instrument is configured as "key verification start" and the magnetic key 11 is not in the adsorption position, the start is refused. Otherwise, the timing is started immediately, the instrument 2 is controlled to move in the initial direction with a preset initial output power, the line arrival signal is listened for, the measurement termination signal is listened for, and the one-way movement distance of the instrument 2 is monitored. When the one-way movement distance reaches the limit value L, the instrument 2 is immediately controlled to reverse and move in the opposite direction and restart monitoring the one-way movement distance. The instrument 2 is controlled to move back and forth in this cycle and does not accept remote control reversing instructions during the measurement. When the line arrival signal is listened for, the timing is immediately ended, the instrument 2 is controlled to stop moving, and the timing result (i.e., the total time from the start of the measurement to the end of the measurement) is output, or when the measurement termination signal (including the abnormal station position signal) is listened for, the instrument 2 is immediately controlled to stop moving and the timing value is canceled, and the current measurement is invalid.

[0075] Furthermore, the embedded software can preferably also control the listening of speed control signals during the measurement, and adjust the output power of the instrument 2 accordingly when the speed control signal is heard. It is also preferably acceptable to set a limit value N of the number of times the line is reached before the measurement is started (the value range is a positive integer ≥1), count the detected line-reaching signals, and when the count reaches the limit value N, it is deemed that the line is finally reached.

[0076] The simplified flow chart of the embodiment of measurement method 2 is as shown in the attached figure. Figure 3 As shown, measuring the dynamic comprehensive basic ability of the subject using the measuring instrument 2 embodiment includes the following steps: Step 1: First, arrange the reach line marking lines at the measurement site according to the measurement specifications. If measurement is required along a broken line trajectory, arrange two or more marking lines and specify the arrival order. If a longer-range measurement is required in a smaller site, only two marking lines are required. Combined with setting the reach number limit N, shuttle automatic measurement with support for ≥1 trips can be achieved. After ensuring the safety of the surrounding environment, turn on the power of the instrument 2; Step 2: Set the gear position of the instrument 2 to determine the one-way length limit value L and the line number limit value N (optional, the default value is 1, set if you need to measure along a broken line trajectory or shuttle measurement, and set the required number of shuttle trips multiplied by 2 for shuttle measurement). The subject wears protective equipment and stands on the pedal of the instrument 2, ensuring that the instrument 2 is at the measurement starting point; Step 3: Sending a measurement start signal to the instrument 2; Step 4: When the instrument 2 detects the measurement start signal, if the instrument is configured as "key verification start" and the magnetic key 11 is not in the adsorption position, the instrument refuses to continue. Otherwise, the instrument immediately starts timing, moves in the initial direction at the preset initial output power, and immediately starts step 5; Step 5: Listen for the measurement stop signal and the line-reaching signal, count, and monitor the one-way moving distance. When the one-way moving distance reaches the limit value L, jump to step 6; when the line-reaching signal count reaches the number limit value N, jump to step 7; when the measurement stop signal (including the abnormal position signal - that is, the subject is offside, falls, or falls) is detected, jump to step 8; when the speed control signal is detected, the output power is adjusted accordingly; during the measurement period, no remote control reversing command is accepted; the subject maintains himself / herself and pushes the pedal with the sole of his / her foot to force the instrument 2 to deviate and move to the line-reaching mark in a predetermined order and direction; Step 6: The instrument 2 automatically reverses and moves in the opposite direction and restarts monitoring the one-way moving distance, and returns to step 5; Step 7: The device 2 immediately ends timing, stops moving, and outputs the timing result—this value is recorded as the subject's dynamic skill value GD2, and the process then proceeds to step 9; Step 8: Stop moving, cancel the timing value, and the current measurement is invalid; Step 9: After the current measurement is completed, prepare for a new measurement or turn off the power of the instrument 2 and put it back in place.

[0077] Technical solution 3 embodiment: Figure 4 This is a schematic diagram of a measuring instrument embodiment 3 of the present invention. This embodiment is based on the aforementioned technical solutions 1 and 2, and creatively combines these two embodiments with the aforementioned solutions B and D. Figure 4 Based on the electric enhanced version of Example 3 of Scheme D, the position monitoring component in the embodiment of the aforementioned Technical Scheme 1 (a universal magnetic reed switch 10 with an iron sheet adhered thereto is used in conjunction with a magnetic key 11) and the line-reaching monitoring component 13 in the embodiment of the aforementioned Technical Scheme 2 are added.

[0078] The reed switch 10 is preferably installed in the upper shell of the embodiment of the above scheme D. There are many models of this universal reed switch on the market. It is beautiful and not easy to damage when it is hidden in the upper shell. Figure 4 Only the approximate installation location is indicated. The infrared diffuse reflection sensor of the line-reach monitoring assembly 13 can be installed on the lower housing or lower housing cover of the embodiment of Solution D, with the infrared transmitter and receiver exposed downward. A narrow LED light strip can also be attached to the inner edge of the upper housing and connected to the main control board assembly to indicate the line-reach status, which is both intuitive and adds a dazzling interactive effect.

[0079] The installation and connection of other hardware components refer to the electric enhancement version of Example 3 of Plan D.

[0080] The embedded software part may preferably include common sub-modules such as instruction parsing and processing, motor control, motor signal monitoring, timing and timing, wireless communication control, display control, audio playback control, position abnormality processing, line signal processing, and data output. It may also include physical fitness measurement module, driving measurement module, practice module, and may also include competition module and massage module.

[0081] Preferably, a remote control device, a smart phone application, a computer and its application, etc. are used to send instruction messages to the microprocessor through a wireless communication module according to an agreed instruction protocol, such as instructing the instrument to select / switch operating mode, set gear, set options, start measurement, adjust speed, tune, reverse, suspend measurement, terminate measurement, read data, etc. The instruction parsing and processing submodule parses the received instruction message into corresponding instructions according to the agreed instruction protocol and calls the corresponding module for processing.

[0082] Among them, when the standing position monitoring component finds that the user's standing position is abnormal (that is, the reed switch 10 described in the embodiment of technical solution 1 is disconnected), it immediately sends a standing position abnormality signal to the physical fitness measurement module, the driving measurement module, the practice module, the competition module, and the massage module via the main control board component, and the corresponding modules perform subsequent processing according to their respective standing position abnormality processing logic; when the line monitoring component monitors the reaching line identification line (the infrared diffuse reflection sensor described in the embodiment of technical solution 1 moves with the instrument to the black tape attached to the identification point), it immediately sends a line reaching signal to the driving measurement module via the main control board component.

[0083] The embedded software is also provided with a plurality of operating modes, preferably including physical fitness measurement mode, driving measurement mode, and practice mode, and may also include competitive mode and massage mode. When the instruction parsing processing submodule parses the instruction to select or switch the operating mode, if the mode is configured as "key verification start" and the magnetic key 11 is not in the adsorption position, it refuses to continue, otherwise the corresponding physical fitness measurement module, driving measurement module, practice module, competitive module or massage module is called respectively. The processing logic of these modules corresponds to the specific implementation methods of the embodiments of the instrument 1, instrument 2, plan B, plan C, and plan D respectively. When the user uses it, after turning on the power of the instrument 3, he can select and switch the operating mode as needed, thereby realizing time-sharing multiplexing of the same instrument and multiple uses of one instrument.

[0084] The above embodiments are merely examples of the division of the above modules. In actual applications, the above functions can be assigned to different functional modules as needed; the modules and components can be separate or integrated; those belonging to the same concept can refer to each other and will not be described separately. The above description is only an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.

The dynamic measurement module starts timing immediately when it detects the measurement start signal, controls the instrument to move in the initial direction with a preset initial output power, listens for the line-reaching signal, listens for the measurement termination signal, and monitors the one-way movement distance of the instrument. When the one-way movement distance reaches the one-way length limit value, it immediately controls the instrument to reverse and move in the opposite direction and restarts monitoring the one-way movement distance. The instrument is controlled to move back and forth in this cycle and does not accept remote control reversing instructions during the measurement until the line-reaching signal is detected and the timing is immediately ended, the instrument is controlled to stop moving, and the timing result is output, or the measurement termination signal is detected and the instrument is immediately controlled to stop moving and the timing value is canceled, and the current measurement is invalid.

7. The instrument according to claim 6, further characterized in that It includes a standing position monitoring component, which is connected to the main control board component. It acts as a safety lock before the measurement is started to limit whether the measurement is allowed to be started. During the measurement process, it continuously monitors whether the subject standing on the pedal falls or falls. Once the subject is found to fall or fall, an abnormal standing position signal is immediately sent to the dynamic measurement module through the main control board component. The dynamic measurement module then processes the abnormal standing position signal as a measurement termination signal.

8. The apparatus according to claim 6 or 7, further characterized in that The dynamic measurement module includes a function of setting a limit on the number of times the line is reached before the measurement is started to support automatic measurement along a broken line trajectory or ≥1 shuttle trips. It can also listen to the speed control signal during the measurement and adjust the output power of the instrument accordingly when the speed control signal is detected.

9. A method for measuring dynamic physical ability, using the apparatus according to claim 6 or 7 to measure the dynamic comprehensive basic ability of the subject, characterized in that The method includes the following steps: arranging the reach line marking line at the measurement site according to the measurement specifications, turning on the power of the instrument after ensuring the safety of the surrounding environment, and setting the gear to determine the one-way length limit value. The subject wears protective equipment and stands on the instrument pedal and ensures that the instrument is at the measurement starting position, and sends a measurement start signal to the instrument. When the instrument detects the measurement start signal, it immediately starts timing, moves in the initial direction with a preset initial output power, listens for the reach line signal, listens for the measurement termination signal, and monitors the one-way movement distance. When the one-way movement distance reaches the one-way length limit value, it immediately changes direction and moves in the opposite direction and restarts monitoring the one-way movement distance. It moves back and forth in this cycle and does not accept remote control reversing instructions during the measurement. The subject maintains himself or herself from falling off the pedal and forcibly pushes the pedal with the sole of the foot to force the instrument to offset and move to the reach line marking line. The instrument immediately ends timing, stops moving, and outputs the timing result when it detects the reach line signal, or immediately stops moving and cancels the timing value when it detects the measurement termination signal.

10. A multifunctional portable body dynamic ability measuring instrument, comprising a pedal, a motor and a bridge assembly, a driven wheel and a bridge assembly, a power supply assembly, a main control board assembly, a motor drive module, and a wireless communication module, characterized in that It includes a standing position monitoring component, a line monitoring component, a physical fitness measurement module, a driving measurement module, and a practice module connected to the main control board component. The integrated operating modes that can be selected and switched by users include physical fitness measurement mode, driving measurement mode, and practice mode. The standing position monitoring component acts as a safety lock before startup to limit whether startup is allowed. During the measurement or practice process, it continuously monitors whether the user standing on the pedal is offside, falls or falls. Once the user is found to be offside, falls or falls, a standing position abnormality signal is immediately sent to one of the physical fitness measurement module, driving measurement module, and practice module corresponding to the current operation mode via the main control board component. The module corresponding to the current operation mode then processes the standing position abnormality signal as a physical fitness measurement termination, driving measurement suspension or practice suspension signal respectively. Only one discrete sensor element is used and only one switch signal is transmitted to simultaneously monitor four abnormalities of absence, offside, falling and falling.
