The control method is as follows. When a user exercises in the treadmill, the frequency and amplitude of the arm swing is detected by the arm swing detecting unit. If the change value of the frequency and amplitude of the arm swing is bigger than a prestore threshold, based on the new frequency and amplitude of the arm swing, the new speed of the belt will be worked out, and the speed of the treadmill will be automatically adjusted to the new speed, otherwise the old speed of the belt will be maintained.
Description
Using the treadmill and its control method of man-machine interaction mode of speed regulation
Technical field
The present invention relates to a kind of treadmill, also relate to the treadmill and realize speed or the method for direction controlling, more particularly to a kind of swing arm information by monitoring user（Frequency and amplitude）, palmic rate, the index such as blood pressure, the method for dynamically adjusting the treadmill of its treadmill belt transfer rate and its realizing speed control and virtual scene direction controlling belongs to body-building apparatus technical field.
Background technology
Treadmill is a kind of using body-building apparatus widely.Distinguished from operation principle, two kinds of mechanical treadmill and treadmill can be divided into.
Mechanical treadmill is the product for comparing early stage.When carrying out fitness training using mechanical treadmill, user drives running Tape movement by the thrust kick of pin, its advantage is the speed that can freely control to run, but because driving the thrust kick of running Tape movement to cause the strain in leg joint when running, to the healthy unfavorable of people, so mechanical treadmill has substantially exited market now.
At present, in the market is widely current treadmill.Treadmill drives running Tape movement using electro-motor by transmission device.When user runs on treadmill belt, the speed run by adjusting oneself is consistent come the speed with running Tape movement.If user thinks the velocity of change oneself, it is necessary to first press the rotating speed of the corresponding button change motor in front of treadmill on control panel with hand to change the speed of running Tape movement, then passively change the velocity of oneself again.This habits and customs that can arbitrarily change oneself velocity in nature with people differs greatly.Meanwhile, people's body during running plays pendulum, and allows him to be gone to search corresponding button with eyes on treadmill control panel and be gone to touch the button with finger, not only cumbersome, and easily runner is divert one's attention, and influences train on.For some young old or in evil case users, in some instances it may even be possible to cause danger.
In order to solve the problem of treadmill is not easy to speed governing, a variety of corresponding technical solutions have been occurred in that now.For example in Patent No. ZL 02148196. 2 patent of invention " optical induction type virtual reality treadmill ", optical sensor is installed in the front and back end of treadmill and both sides, the paces state of people's running is measured by optical sensor, to adjust the speed of treadmill.In Patent No. ZL 02112184. 2 patent of invention " being exclusively used in the control method of treadmill ", in the appropriate area installation detecting device of treadmill, a space induction region is formed, user swings hand to control treadmill speed in corresponding space induction region.In addition, in Chinese invention patent ZL 200410104202. 7, describe a kind of system that treadmill running tape speed is adjusted with current loading difference, the current loading signal that the load-sensing circuit for detecting often tramples user in treadmill belt is transferred to microprocessing unit, and calculate the time difference between its signal, the stable difference comparsion of the difference again with originally measuring, by the size of the difference between newest difference and stable difference, motor is made to drive the faster rotational speed or slack-off or maintenance average rate of treadmill belt.So that when user is moved using treadmill, adjustment that can be appropriate according to itself physical efficiency runs speed and reaches body-building
Effect, more avoid because causing the situation generation that user falls accidentally when the race speed of user is different from the rotating speed of treadmill belt.
Using the treadmill of above method speed regulating method, compared with original needs, button press has certain progress come the treadmill of speed governing on the control panel, but with people usually in outdoor running when can with it is arbitrary adjustment velocity compared to or some bother, and notice when easily disperseing to run, disturb the normal running of people.On the other hand, the paces of detecting system detection people and adjust motor speed in treadmill to make up to the time that the speed specified needs longer, it is small the time required to being regulated the speed so that people quickens one's step or slowed down the time required to paces than treadmill belt, the acceleration and deceleration of people are unable to catch up with the acceleration and deceleration of treadmill, draw back or even fall down when being easily caused when people accelerates and be flushed on instrument board, or slowing down.
There is provided a kind of treadmill adaptive speed regulation control in Chinese utility model patent 200720032627. 0
' device, the input of the treadmill adaptive speed regulation control module is connected with cardioelectric monitor module, speed closed loop module and keypad/display module, and speed closed loop module input is connected with treadmill.The utility model can be according to the speed of the heart rate situation adjust automatically treadmill of user, to reach expected body-building purpose, it is to avoid because amount of exercise is not enough and does not reach body-building effect, or endanger healthy because amount of exercise is excessive.But, heart rate situation is one of factor of user's adjustment velocity.Moreover, the constitution of different users is different.Therefore the applicable surface of this treadmill speed control method is limited, and practicality is unsatisfactory.

Similar with existing treadmill, the treadmill provided by the present invention for using man-machine interaction mode of speed regulation is also with base, the running frame on base and motor, on running frame with motor-operated front and rear roller bearing, the running board on running frame, the treadmill belt for being stretched on front and rear roller bearing and bypassing running board, the stand on base and control panel in stand etc..Be fixed on the pipe of left and right two one or two in stand in addition, can also have on treadmill, liquid crystal display can also be installed on control panel and its control press ' key etc..The design and installation of these above-mentioned function element are the routine techniques that persons skilled in the art are all very familiar with, and are not just described in detail herein.
Motor and control panel in the structured flowchart of first embodiment shown in Figure 1, this treadmill connect connection control circuit respectively.The control circuit can also connect computing unit by interface circuit.In addition, the instruments such as external arms swing detection unit, heart rate detection unit and blood pressure detecting unit are also connected with the control circuit, specific connected mode can be realized by wire circuit mode, it would however also be possible to employ bluetooth infrared waits radio connection realization.In the present embodiment, arms swing detection unit can be by user is hand-held or physical quantity transducer installed in user's wrist, such as velocity sensor, acceleration transducer or gyroscope, heart rate detection unit and blood pressure detecting unit can be realized by existing high-end wrist type electronic sphygmomanometer such as EW3003, HEM-6021 etc..It should be noted that being not limited to use above-mentioned arms swing detection unit, heart rate detection unit and blood pressure detecting unit in treadmill.Every Biomedical Instruments that can be used for user's body index in monitoring motion process all can ' to be used in this treadmill.
Fig. 2 show the second embodiment of this treadmill.Among the embodiment, motor and control panel
Connect connection control circuit respectively, control circuit connects computing unit by interface circuit.Computing unit can be computer, or DSP (digital signal processors）Deng.Arms swing detection unit is directly realized with computing unit to be connected.The embodiment is especially suitable for the situation that arms swing detection unit is realized by video acquisition system by analyzing arms swing image.This expansion will be described in detail further below.
This treadmill is when realizing man-machine interaction speed governing, for the ease of conversing new treadmill belt transfer rate according to new swing arm amplitude or frequency, can increase special arms swing Yu Pao Walk velocity function parameter analysis units.Arms swing records the frequency, amplitude and corresponding treadmill speed of user's swing arm with velocity function parameter analytic unit automatically；By the frequency and amplitude that record and analyze many times swing arm of the user under different treadmill speed, arms swing and velocity function parameter analytic unit can obtain the reduction formula between user's swing arm frequency, amplitude and the velocity or the parameter of function, be easy to treadmill fast and accurately to converse treadmill speed according to swing arm frequency or amplitude.3rd embodiment as shown in Fig. 3 Fig. 6 is to sixth embodiment, and the arms swing can be attached with control circuit with velocity function parameter analytic unit, can also be attached with computing unit.
Shown in Figure 7, this treadmill is when realizing man-machine interaction speed governing, creatively by many indexs such as palmic rate, blood pressure and the swing arm information of user（Frequency and amplitude）Combine, using swing arm information as main basis for estimation, the transfer rate of treadmill belt is targetedly adjusted according to the somatic reaction of user, so as to bring more preferably usage experience to user.
User wears heart rate detection unit and blood pressure detecting unit at wrist first when using this treadmill.Palmic rate and blood pressure parameter when being moved by heart rate detection unit and blood pressure detecting unit dynamic detection user.Palmic rate and blood pressure parameter be may be displayed on the LCDs of control panel, and the effect taken exercise is shown to user., can be in more soft mode if palmic rate and blood pressure parameter are in normal scope in the motion process of user（As using less obvious color and less font）Shown to user；If beyond normal scope, user can also be pointed out in the way of sounding with more obvious text prompt user.
Still, the fitness of everyone user is widely different.For the non-normal range according to palmic rate and blood pressure parameter determined by medical science rule, the somatosensory of everyone reality is simultaneously differed.Some users are strong to the tolerance of tachycardias, and some users are then difficult to the tachycardias for standing the short time.Therefore, the transfer rate of treadmill belt is directly adjusted according to palmic rate and blood pressure parameter, is a kind of way of more machinery it is difficult to take into account the individual difference of each user.
In the present invention, dynamic monitoring swing arm information is passed through（Including amplitude of fluctuation and hunting frequency etc.）Carry out adjust automatically treadmill speed, effectively overcome the shortcoming of above method, user can be allowed to change very much the transfer rate of treadmill belt naturally.
Relevant physiology and kinematics research shows, people when running in order to maintain balance, the substantially proportional relation of amplitude and frequency and the amplitude and frequency of arms swing taken a step.Swing arm frequency is faster, and the frequency of step is just corresponding faster.The amplitude of swing arm is bigger, and the stride of step is just corresponding bigger.In addition, people is when turning, the square of turning also has relation to arms swing.When turning to the left, right arm amplitude of fluctuation is big, and left arm amplitude of fluctuation is small；Turn right
When curved, left arm amplitude of fluctuation is big, and right arm amplitude of fluctuation is small.
If we directly change the frequency or amplitude run on treadmill, our speed change is not caught up with because the speed of treadmill changes, people is easily caused and knocks instrument board or fall down backward.If we on a treadmill ' first change the arm frequency or amplitude brandished, gradually change treadmill speed after associated detection cell is detected and is calculated, the frequency and amplitude that now user runs can be natural as the speed of treadmill changes and changes, people preshoot or will not fall down.Treadmill reaches after new speed that the frequency or amplitude that now arm is brandished can reach harmonious again with the frequency or amplitude run.Therefore, the information brandished by gathering and analyzing arm carries out the speed governing of treadmill, the process of whole speed governing can be made not only natural but also safety.
Around this principle, the method flow diagram shown in reference picture 8.When people runs on a treadmill, arms swing is with taking a step harmonious.If it is desired to allowing treadmill speed to accelerate, as long as accelerating swing arm frequency or increasing swing arm amplitude, detecting system is detected after swing arm frequency or amplitude increase, at once increase treadmill speed, the frequency or amplitude that now leg is taken a step also are accelerated therewith, reach harmonious again with swing arm.If it is desired to allowing treadmill speed to slow down, as long as reducing swing arm frequency or swing arm amplitude, detecting system is detected after swing arm frequency or amplitude reduction, reduces treadmill speed at once, the frequency or amplitude that now leg is taken a step also reduce therewith, reach harmonious again with swing arm.
The speed of treadmill is approximate with frequency with the amplitude of user's swing arm to meet a reduction formula：V=F (r, f).Wherein V is the speed of treadmill, r is the amplitude of user's swing arm, f is the frequency of swing arm, F () is a function, the parameter of the function is related to everyone running feature, generally remain stable to a certain user, may be constructed a metastable change curve.For example：If keeping swing arm frequency constant, swing arm amplitude increases m times, then the amplitude of taking a step that people runs in the case of outdoor running can also increase n times（M and n ratio is for some one metastable change curve of personal substantially satisfaction）, then the velocity equivalent to people can increase n times, so the rotating speed of treadmill can be increased n times by us.And for example：If keeping swing arm amplitude constant, swing arm frequency increases m times, then the frequency of taking a step that people runs in the case of outdoor running can also increase n times（M and n are roughly equal under normal circumstances）, then the velocity equivalent to people can increase n times, so the rotating speed of treadmill can be increased n times by us.If swing arm amplitude and frequency change simultaneously, consider the two factors to adjust treadmill speed simultaneously.
In order to allow user to be more easily adapted to conform to new velocity, when treadmill speed changes with the frequency or amplitude of swing arm, treadmill can be gradually transitions new speed from original speed, allow user to have the process of an adaptation, prevent the speed suddenly change of treadmill from causing user to fall down or other discomforts.
Before treadmill dispatches from the factory, one group of function reduced parameter value being extract for most people can be pre-set in the control circuit of treadmill, the need for it can meet user.If it is desired to allowing treadmill more suitable for the concrete condition of some user, the function or the specific reduced parameter value of curve can be set by user on treadmill control panel, to be adapted to the running feature of some user.
In order to more accurately obtain the parameter value that the function is directed to a certain user, arms swing and velocity function parameter analytic unit are provided with treadmill.When in use, user can both use the ordinary control mode that treadmill speed is controlled by control panel to this treadmill, can also be switched to swing arm control model by switching switch.In the case where controlling the ordinary control mode of treadmill speed by control panel, arms swing can record the frequency of user's swing arm, amplitude automatically with velocity function parameter analytic unit and think corresponding treadmill speed therewith；In pendulum
Under arm control model, when swing arm frequency and amplitude and velocity reach it is stable after, arms swing can also record the frequency of user's swing arm, amplitude automatically with velocity function parameter analytic unit and think corresponding treadmill speed therewith.By recording and analyzing the frequency and amplitude of many times swing arm of the user under different treadmill speed, arms swing and velocity function parameter analytic unit can finally obtain the reduction formula between user's swing arm frequency, amplitude and the velocity or the parameter of function by self-learning methods such as artificial neural networks.Under swing arm control model, it is possible to directly using these parameters, not only facilitated but also accurate.The self-learning algorithms such as this artificial neural network are the routine techniques that software field those skilled in the art can grasp, and are not just described in detail herein.
The amplitude of swing arm and the detection method of frequency can have a variety of.The first method is respectively to hold an acceleration transducer or gyroscope by the both hands of user.They can detect the parameters such as speed, acceleration, the direction of arms swing, and calculate frequency and amplitude, then be transferred to control circuit by bluetooth or wireless module.Second of method is that a device is respectively worn on the both hands arm or wrist of user, inside it is filled with acceleration transducer or gyroscope, the parameters such as speed, acceleration, the direction of arms swing can be detected, and frequency and amplitude are calculated, control circuit is then transferred to by bluetooth or wireless module.Above two method is suitable for the treadmill described in above-mentioned first embodiment.
The third method is that arms swing video image is directly gathered by video acquisition system, and the amplitude and frequency of arms swing are calculated according to image, and transfers data to control circuit.This method is suitable for above-mentioned second and implemented
Electricity Dong Pao Walk machines described in example.
When stating the third method on the implementation, in order to allow during people's running swing arm the swing arm frequency caused unintentionally or changes in amplitude not to influence the operating of Pao Walk machines, a threshold value can be set in control circuit, as long as the frequency or amplitude of swing arm after changing are more than this threshold value relative to the difference of previous stationary value, control circuit just sends instruction to treadmill, allows treadmill to change speed.So doing can be so that people be when normally at the uniform velocity running, although arms swing amplitude or frequency might have slight change, but treadmill can also keep hooking speed.This threshold value can carry out appropriate adjustment according to the situation of oneself on treadmill instrument board so that the speed governing for running Walk machines is more suitable for the custom of individual.
In order to ensure the physical and mental health of user, during by dynamic monitoring swing arm information adjust automatically treadmill speed, if palmic rate and blood pressure parameter are in normal scope, allow to increase or reduce treadmill belt transfer rate according to the amplitude or frequency of the arms swing of user；But if palmic rate and blood pressure parameter then can only reduce treadmill belt transfer rate according to the amplitude or frequency of arms swing and can not increase transmission beyond normal scope
Speed.
Speed can both be changed by swing arm, direction can also be changed, in order to prevent that the asynchronous swing of two-arm causes treadmill velocity variations so as to reducing stationarity when the people in controlling virtual scene turns, detection process can be divided into by two kinds of situations according to the difference of swing arm frequency or amplitude between two-arm.It is now straight trip running state, system changes treadmill speed according to swing arm frequency or amplitude, do not change running direction when the difference of swing arm frequency or amplitude between two-arm is less than some threshold value.When the difference of swing arm frequency or amplitude between two-arm is more than some threshold value, it is now turning running state, system only changes the people's turn direction and radius of turn in virtual scene according to the difference of two-arm swing arm frequency or amplitude, does not change treadmill speed according to swing arm frequency or amplitude.Certainly, discounting for stationarity, it is necessary to which more direct control treadmill speed and direction, can not also increase this limitation.
, Pao Walk machines are also connected by data-interface with computing unit in itself in the present invention, speed that people is run or
The Virtual that direction is passed on computing unit in real time intends scene software.The virtual scene software can show the speed and direction that people runs in virtual scene, and the speed and direction controlling virtual scene of user's running by the display on control panel, reach the purpose that New Zealand Journal of Health Physical Education is combined.In this case, if it is desired to the personage allowed in virtual scene turns, it is only necessary to make the frequency or amplitude of double arm swing inconsistent.Such as to turn to the left, then increase right arm amplitude of fluctuation or frequency, reduce left arm amplitude of fluctuation or frequency；When bending to right, then left arm amplitude of fluctuation or-frequency are increased, reduce right arm amplitude of fluctuation or frequency.
The treadmill and its control method of use man-machine interaction mode of speed regulation of the present invention are described in detail above, it is apparent that the form that implements of the present invention is not limited thereto.For the those skilled in the art of the art, in the case of without departing substantially from scope of the presently claimed invention to it carry out it is various it is obvious change all within protection scope of the present invention.
