It is right with reference to embodiment and accompanying drawing for the purpose, technical scheme and advantage of the disclosure are more clearly understood The disclosure is described in further details.Here, the exemplary embodiment of the disclosure and its illustrate to be used to explain the disclosure, but simultaneously Not as the restriction to the disclosure.

The embodiment of the present disclosure provides a kind of treadbelt method for control speed, device, treadmill and storage medium, below in conjunction with attached The disclosure is described in detail figure.

Fig. 2A is a kind of side cutaway view of treadmill according to an exemplary embodiment, and Fig. 2 B are the treadmills Schematic top plan view, the treadmill include processor 201, motor 202, front end roller 203, rear end roller 204, race plate 205, treadbelt 206th, pressure sensor 207 and support feet 208 (processor 201 and motor 202 are not shown in figure).

Processor 201 is electrically connected with motor 202, and motor 202 is connected with front end roller 203, and processor 201 is used to pass through electricity Machine 202 controls front end roller 203 and rear end roller 204 to rotate.Front end roller 203 and rear end roller 204 are positioned at the two of race plate 205 End, treadbelt 206 are rolled positioned at the outside for running plate 205, front end roller 203 and rear end roller 204, and in front end roller 203 and rear end When cylinder 204 rotates, treadbelt 206 moves around front end roller 203 and rear end roller 204 towards the direction of treadmill rear end.

Wherein, the principle of treadbelt 206, front end roller 203 and the rotation of rear end roller 204 can be：Motor 202 drives front end Roller 203 rotates, and front end roller 203 drives treadbelt 206 to be moved to the rear end of treadmill, and treadbelt 206 drives 204 turns of rear end roller It is dynamic.

The structure that plate 205 can be hard is run, treadbelt 206 can be supported when treadbelt 206 is under pressure, avoid treadbelt 206 sink and deform.

Pressure sensor 207, which is fixed on, to be run on plate 205, such as race plate 205 can include specifying groove, pressure sensor 207, which are fixed on this, specifies in groove.In addition, the lower section of pressure sensor 207 can set stud, the stud is used to support and consolidated The fixed pressure sensor 207.Pressure sensor 207 is used to detect the pressure value that treadbelt 206 is subject to, and pressure sensor 207 Center and support feet 208 are centrally located on the same straight line of treadbelt 206 (that is, perpendicular to travel around taking general charge of an entire area at the grass-roots level).Wherein, support Pin 208 is the stress strong point of treadmill, i.e. the maximum position of treadmill stress, is arranged on relative to by pressure sensor 207 For other positions, pressure sensor 207 and support feet 208, which are correspondingly arranged, can ensure that pressure sensor 207 detects pressure The process of value is sensitiveer, and the degree of accuracy is higher.

During user runs in treadbelt 206, foot's (such as sole) can impact treadbelt 206, and treadbelt 206 can be by Pressure, and then produce pressure, pressure sensor 207 and race the being fixed as one structure, therefore can examine of plate 205 to running plate 205 Measure and run the pressure value that plate 205 is subject to, the pressure value may be considered the pressure value that treadbelt 206 is subject to.Processor 201 is used to obtain The pressure value that pressure force snesor 207 detects, the velocity of rotation of front end roller 203 is controlled according to pressure value, run so as to control With 206 speed so that treadbelt 206 moves according to corresponding speed.

Wherein, pressure sensor 207 can connect with Acquisition Circuit, and Acquisition Circuit and processor 201 connect, processor 201 can gather the pressure value that detects of pressure sensor 207, the collection period according to collection period, and by Acquisition Circuit Can be 18ms or 28ms etc..

In another embodiment, on the basis of the treadmill shown in Fig. 2A and Fig. 2 B, referring to Fig. 2 C, it illustrates one kind The top view of treadmill, support feet 208 include the first support feet 2081 and the second support feet 2082, and the first support feet 2081 is located at First outside of treadbelt 206, such as the left side during user's running, the second support feet 2082 are located at the second of treadbelt 206 Right side during outside, such as user's running, the first support feet 2081 and the second support feet 2082 and the front end of treadmill The distance between the distance between be less than with rear end of treadmill, i.e. the first support feet 2081 and the second support feet 2082 is run The support feet of machine front end.

Correspondingly, pressure sensor 207 includes first pressure sensor 2071 and second pressure sensor 2072, the first pressure The center of force snesor 2071 and the first support feet 2081 are centrally located in same vertical line, second pressure sensor 2072 Center and the second support feet 2082 be centrally located in same vertical line.

User run during, first pressure sensor 2071 apart from the position of user's left foot closer to, therefore detect To pressure value can more reflect the motion conditions of user's left foot, and second pressure sensor 2072 apart from the position of user's right crus of diaphragm more Closely, therefore the pressure value that detects can more reflect the motion conditions of user's right crus of diaphragm, then treadmill can be respectively according to two pressure Sensor determines the motion conditions of user's left foot and right crus of diaphragm, the speed of the motion conditions control treadbelt of comprehensive both feet.In addition, two Pressure sensor can backup sensors each other, i.e. when any one pressure sensor damages, treadmill can obtain another The pressure value that pressure sensor detects, to control the speed of treadbelt according to the pressure value.

In a kind of possible implementation, referring to Fig. 3, the race plate 205 of treadmill can include first and run plate portion and the Two run plate portion, and the front end of the first race plate portion is the front end of treadmill, seam be present between the first race plate portion and the second race plate portion 209.Wherein, gathering can be folded at seam 209 and get up by running plate 205, i.e., the treadmill is foldable running apparatus.Further Ground, the lower section of seam 209 can set the 3rd support feet 2083, and the 3rd support feet 2083 is used to support the seaming position 209, prevented Plate 205 is only run to sink due to being under pressure to bend at the seam 209 in the course of the work.

With 209 corresponding position of seam it is calibration position in treadbelt, when the foot of user is located at the calibration position of treadbelt, The pressure value that pressure sensor detects is 0.This is because, run plate first run plate portion, seam 209 and second run plate portion by Power is separate, when user foot positioned at travel around taking general charge of an entire area at the grass-roots level it is upper from position corresponding to seam 209 to any one position of rear end when, the first race The pressure that plate portion is subject to is 0, then the pressure value detected positioned at the pressure sensor 207 for running front edge of board is 0.

It should be noted that treadmill can also include being arranged at handrail, operating desk of the top of treadbelt 206 etc., Yong Huke To control treadmill by triggering various operations on operating desk.Processor 201, which can be arranged at, to be run inside plate 205, or It is arranged in operating desk, motor 202, which can be arranged at, to be run inside plate 205, or is directly arranged at two drums insides.

The treadmill that correlation technique provides needs to detect the position of stopping over of user by the array of pressure sensors configured, Treadbelt speed change can be automatically controlled, is accurately stopped over position to detect, array of pressure sensors usually requires to configure several Ten pressure sensors, but the number of pressure sensor is more, hardware cost is higher, and the required space that occupies is bigger, different The cooperation circuit that pressure sensor is connected with each other is more complicated, and integrated difficulty is bigger.Also, the number of pressure sensor is got over More, the probability of failure is bigger, and the difficulty safeguarded is also bigger, causes the stability of treadmill also poor.

And the treadmill that the embodiment of the present disclosure provides, the function of processor is improved, only need to configure one or two Individual pressure sensor, you can the pressure value according to detecting automatically controls treadbelt speed change, without configuring excessive pressure sensor, Reduce the number of pressure sensor, so as to the space for reducing hardware cost He occupying, reduce design and coordinate circuit and collection Into the difficulty of process, and it is easy to maintain, the probability of treadmill failure is reduced, improves the stability of treadmill.

Fig. 4 A are a kind of flow charts of treadbelt method for control speed according to an exemplary embodiment, such as Fig. 4 A institutes Show, the executive agent of this method is the treadmill shown in above-mentioned Fig. 2A and Fig. 2 B, is comprised the following steps：

In step 401, the currently detected primary peak pressure value of pressure sensor of treadmill configuration and upper is obtained The secondary peak pressure value that one-time detection arrives.

Afterwards, the size of primary peak pressure value and secondary peak pressure value can be compared for treadmill, be compared As a result, for the different situations of comparison result, step 402 or step 403 are performed.

Pressure sensor has been pre-set in treadmill, the pressure sensor can detect in real time treadbelt currently by The pressure value arrived, then treadmill can gather the pressure value that pressure sensor detects.For example, it can be gathered according to collection period The pressure value that pressure sensor detects, the collection period can be 18ms or 28ms etc..

During user runs in treadbelt, foot can carry out the do action of " stop over-foot-up-stop over ".Correspondingly, Awave variation tendency can be presented in the pressure value that pressure sensor detects, i.e. " crest pressure value-trough pressure value-crest Pressure value ".Wherein, the foot of user is once referred to as a landing cycle from the process for falling on treadbelt and up to leaving treadbelt, To land the maximum in the multiple pressure values detected in the cycle, trough pressure value detects crest pressure value to land in the cycle To multiple pressure values in minimum value.

The reason for this variation tendency is presented is, right when foot drops down onto treadbelt during user steps a step Treadbelt produces impact, and the pressure that treadbelt is subject to reaches maximum, and correspondingly, the pressure value that pressure sensor detects reaches crest pressure Force value；During foot slides backward with the movement of treadbelt, the pressure that treadbelt is subject to is reduced, correspondingly, pressure sensing The pressure value that device detects can be gradually reduced from crest pressure value；When foot lifts from treadbelt, the pressure that treadbelt is subject to reaches Minimum, correspondingly, the pressure value that pressure sensor detects can reach trough pressure value.It that is to say, fall the action meeting of foot Crest pressure value is produced, trough pressure value can be produced by lifting the action of foot.

The action that foot is fallen with user due to crest pressure value is associated, and the variation tendency of crest pressure value size can be anti- Reflect the variation tendency that user falls the action of foot.Therefore, can be obtained in the present embodiment pressure sensor it is currently detected One crest pressure value and the last secondary peak pressure value detected, so that the change of subsequent process analysis crest pressure value becomes Gesture, so as to know that user falls the variation tendency of the action of foot.

Wherein, for the process of acquisition primary peak pressure value, detected in order in time from pressure sensor each Crest pressure value is determined in pressure value, the present embodiment can detect every using crest value probe algorithm detection pressure sensor Individual pressure value：

Whenever the pressure value of pressure sensor detection is collected, by the pressure value and the last collection of the pressure sensor To pressure value be compared, when the pressure value that this is collected is bigger than the pressure value that collects of last time, pressure can be known Force value is in ascendant trend, when the pressure value that this is collected is smaller than the pressure value that the last time collects, can know pressure Force value is in downward trend.So, for the pressure value that some is collected, if at pressure value before the pressure value In ascendant trend, and pressure value is in downward trend after the pressure value, then can be using the pressure value as crest pressure value.With reference to The design, the present embodiment are provided with the first preparatory condition, when multiple pressure values that pressure sensor detects include meeting The pressure value of one preparatory condition, the pressure value of preparatory condition will be met as crest pressure value, wherein, first preparatory condition is Pressure value is more than a upper pressure value and is more than next pressure value.

Further, it is contemplated that multiple pressure values before can also working as some pressure value are continuously in ascendant trend, and Pressure value is in downward trend after the pressure value, then using the pressure value as crest pressure value.Correspondingly, the first default bar Multiple pressure values before part could be arranged to pressure value are incremented by successively, and pressure value is more than next pressure value, the plurality of pressure The number of force value can determine according to the actual requirements.

In a kind of possible implementation, for the ease of storage and marking wave peak pressure force value, treadmill can be pressure Sensor establishes crest queue, and each crest pressure value of the pressure sensor got is stored in crest queue, Then crest queue can be used for recording multiple crest pressure values that pressure sensor has been detected by, and the plurality of crest pressure value can To be arranged according to the order for obtaining time point from evening to morning.

So, when treadmill gets current primary peak pressure value, first can be read from crest queue current The crest pressure value to make number one, the crest pressure value are the last crest pressure value got, therefore can conduct Secondary peak pressure value, then the primary peak pressure value newly obtained is added to first of crest queue.

Or when treadmill gets current primary peak pressure value, first primary peak pressure value can be added To first of the crest queue, then read from crest queue and currently come deputy crest pressure value, as the second ripple Peak pressure force value.

It should be noted that treadmill can configure two pressure sensors：First pressure sensor and second pressure pass Sensor, then in another embodiment, referring to Fig. 4 B, this step 401 can be replaced by following steps 411：

In step 411, the currently detected primary peak pressure value of first pressure sensor and last detection are obtained The secondary peak pressure value arrived, and the currently detected primary peak pressure value of second pressure sensor and last time detect Secondary peak pressure value.

Wherein it is possible to establish primary peak sequence for first pressure sensor, and second is established for second pressure sensor Crest queue, primary peak queue include order row that first pressure sensor detects, according to acquisition time point from evening to morning Row multiple crest pressure values, secondary peak queue include second pressure sensor detection, according to obtain time point from evening to Early tactic multiple crest pressure values.

In step 402, when primary peak pressure value is more than secondary peak pressure value, the treadbelt speed of treadmill is entered Row adjustment, so that treadbelt accelerates.

On the one hand, because the distance of user foot and pressure sensor is smaller, crest pressure that pressure sensor detects Value is bigger, when primary peak pressure value is more than secondary peak pressure value, shows the crest pressure value that pressure sensor detects For ascendant trend, you can to know that user foot may be close to pressure sensor.Again because pressure sensor is located at treadbelt Front end, then show that user foot is just gradually forward, user may accelerate.

On the other hand, due to when user falls foot impact of the foot to treadbelt it is bigger, the ripple that pressure sensor detects Peak pressure force value would generally be bigger, and when primary peak pressure value is more than secondary peak pressure value, i.e., pressure sensor detects When crest pressure value is ascendant trend, then show that user falls the dynamics used during foot and may strengthened, user may be Accelerate.

In summary, when primary peak pressure value is more than secondary peak pressure value, it may be determined that user is accelerating, then in order to The speed at family is shared, treadbelt should also be as being accelerated.

The mode accelerated for control treadbelt, substantial amounts of acceleration empirical data, every acceleration experience number can be obtained in advance According to include mutually corresponding to present speed, adjacent pressure crest value pressure difference value, accelerate after speed, according to acquisition plus Fast empirical data is fitted, and obtains the first acceleration control function, and the input of the first acceleration control function is present speed, phase The pressure difference value of adjacent pressure crest value, the speed after exporting as acceleration.

Wherein, for the process being fitted, the original acceleration control function that coefficient is undetermined can be set, by substantial amounts of Empirical data is accelerated to be trained the coefficient of original acceleration control function, so as to being adjusted to coefficient so as to adjust and be Speed after the acceleration that several acceleration control functions is exported, which more approaches, accelerates the speed after preferably accelerating in empirical data, Regulation coefficient again afterwards, when accelerating control function and the matching of as far as possible more acceleration empirical datas training complete, obtain first Accelerate control function.

After the first acceleration control function is obtained, when controlling the treadbelt to accelerate, current speed is obtained, and calculate the second ripple The pressure difference value of peak pressure force value and primary peak pressure value, accelerate control function using first, to present speed and pressure difference value Calculated, you can the speed after being accelerated, the speed of treadbelt is adjusted to the speed after accelerating.

Need to illustrate first point is, corresponding with above-mentioned steps 411, in another embodiment, referring to Fig. 4 B, this step 402 can be replaced by following steps 412：

In step 412, when the currently detected primary peak pressure value of first pressure sensor passes more than first pressure The secondary peak pressure value that the sensor last time detects, and second pressure sensor it is currently detected primary peak pressure value it is big During the secondary peak pressure value detected in the second pressure sensor last time, the treadbelt speed of treadmill is adjusted, with Accelerate treadbelt.

That is, when user's both feet close to front end or are being had an effect being gradually increased, then it can determine that user is adding Speed, then treadbelt should also be as being accelerated.

In step 403, when primary peak pressure value is less than secondary peak pressure value, the treadbelt speed of treadmill is entered Row adjustment, so that treadbelt is slowed down.

On the one hand, because the distance of user foot and pressure sensor is bigger, crest pressure that pressure sensor detects Value would generally be smaller, when primary peak pressure value is less than secondary peak pressure value, shows the crest that pressure sensor detects Pressure value is downward trend, then can know that user foot may be away from pressure sensor.Again because pressure sensor is located at The front end of treadbelt, then show user foot just gradually rearward, user may slow down.

On the other hand, due to when user falls foot foot it is smaller to the impulsive force of treadbelt, what pressure sensor detected Crest pressure value would generally be smaller, and when primary peak pressure value is less than secondary peak pressure value, i.e., pressure sensor detects Crest pressure value when being downward trend, then would know that user falls the dynamics used during foot and weakened, user may be Slow down.

In summary, when primary peak pressure value is less than secondary peak pressure value, it may be determined that user is being slowed down, then in order to The speed at family is shared, treadbelt should also be as being slowed down.

The mode slowed down for control treadbelt, the present speed of treadbelt can be obtained, calculate primary peak pressure value and the The pressure difference value of two crest pressure values, using the first deceleration control function, present speed and pressure difference value are calculated, obtained Speed after deceleration, the speed of treadbelt is adjusted to the speed after slowing down, the first deceleration control function passes through to mutually corresponding Speed after present speed, the pressure difference value of adjacent peaks pressure value, deceleration is fitted to obtain, and fit procedure accelerates with first Control function is similar.

Need to illustrate first point is, corresponding with above-mentioned steps 411, in another embodiment, this step 403 can by with Lower step 413 replaces：

In step 413, when the currently detected primary peak pressure value of first pressure sensor passes less than first pressure The secondary peak pressure value that the sensor last time detects, and second pressure sensor it is currently detected primary peak pressure value it is small During the secondary peak pressure value detected in the second pressure sensor last time, the treadbelt speed of treadmill is adjusted, with Treadbelt is set to slow down.

That is, when user's both feet away from front end or are being had an effect being gradually reduced, then it can determine that user is subtracting Speed, then in order to coordinate the speed of user, treadbelt should also be as being slowed down.

In another embodiment, it is contemplated that during the trend of analysis user movement situation, the crest of continuous two step should be used Pressure value, the variation tendency of the crest pressure value size without discontinuous two step should be used, such as the running in treadbelt In, user leaves treadbelt rest, when setting foot on treadbelt again afterwards, the crest pressure value of final step when leaving and and when setting foot on Although the first step crest pressure value in crest queue position it is adjacent, be not actually continuous two step, it is impossible to as Determine the foundation of user movement trend.Therefore, the acquisition time point of primary peak pressure value and secondary peak pressure value can be worked as When close enough, then running speed change is controlled, then can be replaced referring to Fig. 4 C, above-mentioned steps 402 by following steps 422, above-mentioned step Rapid 403 can be replaced by following steps 423：

In step 422, when primary peak pressure value is more than secondary peak pressure value, and when primary peak pressure value When time interval between acquisition time point and the acquisition time point of secondary peak pressure value is less than prefixed time interval, to running The treadbelt speed of machine is adjusted, so that treadbelt accelerates.

In step 423, when primary peak pressure value is less than secondary peak pressure value, and when primary peak pressure value When time interval between acquisition time point and the acquisition time point of secondary peak pressure value is less than prefixed time interval, to running The treadbelt speed of machine is adjusted, so that treadbelt is slowed down.

When the time interval obtained between time point of primary peak pressure value and secondary peak pressure value is less than default Between when being spaced, show that the acquisition time point of primary peak pressure value and secondary peak pressure value is close enough, now can just control Treadbelt accelerates, wherein, prefixed time interval is used for the maximum time interval for indicating continuous two step, can be the empirical value of acquiescence, It can be set in advance in treadmill by developer.

In another embodiment, in order to avoid the influence that cas fortuit is brought, primary peak pressure value and second can be worked as When gap between crest pressure value is sufficiently large, then control running speed change.Then can be by following referring to Fig. 4 D, above-mentioned steps 402 Step 432 is replaced, and above-mentioned steps 403 can be replaced by following steps 433：

In step 432, when primary peak pressure value is more than secondary peak pressure value, and primary peak pressure value and second When the difference of crest pressure value is more than the first preset difference value, the treadbelt speed of treadmill is adjusted, so that treadbelt accelerates.

When the difference of primary peak pressure value and secondary peak pressure value is more than the first preset difference value, show first wave peak pressure The amplitude that force value is more than secondary peak pressure value is sufficiently large, now can just control treadbelt to accelerate, and is brought with to avoid cas fortuit Error.Wherein, minimal difference when first preset difference value instruction triggering treadbelt accelerates between two adjacent peaks pressure values, it is Weigh the standard of the size of the difference between two adjacent peaks pressure values.First preset difference value can be the empirical value of acquiescence, It can also be set in advance in treadmill by developer.

On the setting up procedure of first preset difference value, the process that user runs in treadbelt can be surveyed in advance Examination, is obtained when user is larger relative to the speed of treadbelt, i.e., when user accelerates, the adjacent peaks pressure value that detects Difference, by counting mass data, the scope that the difference of crest pressure value is generally fall into is determined, minimum is chosen from the scope Pressure mean values are as the first preset pressure value.

This step 432 so that the difference of primary peak pressure value and secondary peak pressure value is more than the first preset difference value as an example, And when the difference between primary peak pressure value and secondary peak pressure value is not more than the first preset difference value, show primary peak Pressure value and secondary peak pressure value are closer to, i.e., the adjacent crest pressure value changes detected twice of pressure sensor are not Greatly, in such a case, it is possible to which the crest pressure value detected according to upper last time controls treadbelt speed, it that is to say that this method may be used also To comprise the steps 4321-4322：

In step 4321, when primary peak pressure value is more than secondary peak pressure value, and primary peak pressure value and the When the difference of two crest pressure values is not more than the first preset difference value, the 3rd crest pressure value that pressure sensor detects is obtained.

3rd crest pressure value is last the crest pressure value detected before secondary peak pressure value.Relative to For currently detected crest pressure value, the 3rd crest pressure value is the crest pressure value detected upper last time.Implementing When, it can read and the crest pressure value of the 3rd is currently come in crest queue, as the 3rd crest pressure value.

In step 4322, when primary peak pressure value is more than the 3rd crest pressure value, and primary peak pressure value and the When the difference of three crest pressure values is more than three preset difference values, the treadbelt speed of treadmill is adjusted, so that treadbelt accelerates.

Wherein, the 3rd preset difference value is used for two ripples for indicating one crest pressure value of midfeather that triggering treadbelt accelerates Minimal difference between peak pressure force value, it can be the empirical value of acquiescence, can be set in advance in treadmill by developer.The The setting up procedure of three preset difference values is similar with the setting up procedure of the first preset difference value, will not be described here.

In step 433, when primary peak pressure value is less than secondary peak pressure value, and secondary peak pressure value and first When the difference of crest pressure value is more than the second preset difference value, the treadbelt speed of treadmill is adjusted, so that treadbelt is slowed down.

When the difference of secondary peak pressure value and primary peak pressure value is more than the second preset difference value, show secondary peak pressure The amplitude that force value is more than primary peak pressure value is sufficiently large, now can just control treadbelt to slow down, and is brought with to avoid cas fortuit Error.Wherein, minimal difference when second preset difference value instruction triggering treadbelt is slowed down between two adjacent peaks pressure values, it is Weigh the standard of the size of the difference between two adjacent peaks pressure values.Second preset difference value can be the empirical value of acquiescence, It can be set in advance in treadmill by developer.The setting of the setting up procedure of second preset difference value and the first preset difference value Journey is similar, will not be described here.

This step 433 so that the difference of secondary peak pressure value and primary peak pressure value is more than the second preset difference value as an example, And when the difference between secondary peak pressure value and primary peak pressure value is not more than the second preset difference value, show primary peak Pressure value and secondary peak pressure value are closer to, i.e., the adjacent crest pressure value changes detected twice of pressure sensor are not Greatly, in such a case, it is possible to continue executing with following step 4331-4332：

In step 4331, when primary peak pressure value is less than secondary peak pressure value, and secondary peak pressure value and the When the difference of one crest pressure value is not more than the second preset difference value, the 3rd crest pressure value is obtained；

In step 4332, when primary peak pressure value is less than the 3rd crest pressure value, and the 3rd crest pressure value and the When the difference of one crest pressure value is more than four preset difference values, the treadbelt speed of treadmill is adjusted, so that treadbelt is slowed down.

Wherein, the 4th preset difference value is used for two ripples for indicating one crest pressure value of midfeather that triggering treadbelt is slowed down Minimal difference between peak pressure force value, it can be the empirical value of acquiescence, can be set in advance in treadmill by developer.The The setting up procedure of four preset difference values is similar with the setting up procedure of the first preset difference value, will not be described here.

Need to illustrate first point be, includes first pressure sensor and second pressure sensor for pressure sensor Situation, referring to Fig. 4 E, first pressure sensor and second pressure sensor detect that the time point of each crest pressure value can phase Together, the concrete numerical value detected is typically different.This is because, when user's left foot is fallen, two pressure sensors can be simultaneously Crest pressure value is detected, and first pressure sensor is located at left side, therefore the crest pressure value detected can be more than the second pressure The crest pressure value that force snesor detects.When user's right crus of diaphragm is fallen, two pressure sensors can be detected simultaneously by crest pressure Force value, and second pressure sensor is located at right side, therefore the crest pressure value detected detects more than first pressure sensor Crest pressure value.

The second point for needing to illustrate is that pressure value refers both to the fine pressure that the motion process of user applies to treadbelt in the present embodiment Force value.In actual applications, each pressure sensor can also detect the pressure value that the gravity belt of treadbelt in itself is come, in treadmill During startup, pressure sensor can correct currently detected pressure value automatically, and pressure value is subtracted into the next pressure of treadbelt gravity belt Value, to avoid influence of the treadbelt gravity to detection pressure value process.

A kind of method that the present embodiment provides, there is provided mode for controlling treadbelt speed, pressure sensor inspection can be obtained The two adjacent peaks pressure values measured, the variation tendency of crest pressure value size is determined, so as to know user's both feet motion Variation tendency, to control the speed of treadbelt.This method only need to automatically control treadbelt speed change according to the pressure value detected, without The limitation for the number of sensors that can be under pressure, therefore reduce the number of pressure sensor, so as to reduce hardware cost and account for According to space, reduce the difficulty that design coordinates circuit and integrating process, and easy to maintain, reduce treadmill failure Probability, improve the stability of treadmill.

Fig. 5 is a kind of flow chart of treadbelt method for control speed according to an exemplary embodiment, as shown in figure 5, The executive agent of this method is the treadmill shown in above-mentioned Fig. 2A, is comprised the following steps：

In step 501, the number of the crest pressure value got before counting current point in time in preset duration.

The preset duration can be the value no more than 5s, such as can be 4s, or be other values.The preset duration can be with Set in advance in treadmill by developer.Treadmill can obtain crest pressure value by the pressure sensor configured, should It is similar with above-mentioned steps 401 to obtain the process of crest pressure value, will not be described here.

Wherein it is possible to crest queue is established for crest pressure value, whenever crest pressure value is detected, by crest pressure value Added in crest queue.So, this step 501 can be actually：When acquisition time point is located at current in statistics crest queue Between put before preset duration in crest pressure value number.For example, it may be determined that terminated using current point in time as the time Point and time interval be preset duration specified time section, count crest queue in obtain time point belong in the specified time section Crest pressure value number.

It should be noted that the pressure sensor in the present embodiment can include first pressure sensor and second pressure passes Sensor, because two pressure sensors detect that the time point of crest pressure value is identical, then two pressure pass in same amount of time The number for the crest pressure value that sensor is got is identical, therefore during the number of statistics crest pressure value, counts some pressure biography The number for the crest pressure value that sensor detects in preset duration.So, two pressure sensors can serve as mutually standby With equipment, when any one pressure sensor damages, the number of another pressure sensor collection crest pressure value is directly counted , can't influence to control the accuracy of treadbelt rate process.

In step 502, when the number of crest pressure value is more than the first preset number, the treadbelt speed of treadmill is entered Row adjustment, so that treadbelt accelerates.

One crest pressure value can be produced when falling foot every time due to user, then crest pressure value in preset duration Number is the number that user falls foot in preset duration, i.e. the paces number of user, therefore when the number of crest pressure value During more than the first preset number, show that user's paces number in preset duration is more than the first preset number, cadence is very fast, can be with Think that user ramps up, then treadbelt can be controlled to accelerate.Wherein, the first preset number is used to indicate what triggering treadbelt accelerated The crest pressure value number at least counted in preset duration.First preset number can be the empirical value of acquiescence, Ke Yiyou Developer is set in treadmill in advance.

Mode for setting first preset number, the process that user runs in treadbelt can be surveyed in advance Examination, the number of the crest pressure value detected when user accelerates is obtained, the crest pressure value accelerated by counting a large number of users Number, determine the scope that the number of crest pressure value is generally fall into, the number of minimum crest pressure value chosen from the scope Mesh is as the first preset number.

The mode accelerated for control treadbelt, substantial amounts of acceleration empirical data, every acceleration experience number can be obtained in advance According to include mutually corresponding to present speed, crest pressure value number, accelerate after speed, according to the acceleration experience number of acquisition According to being fitted, the second acceleration control function is obtained, the input of the second acceleration control function is present speed and crest pressure The number of value, output are the speed after acceleration.

Wherein, for the process being fitted, the original acceleration control function that coefficient is undetermined can be set, by substantial amounts of Empirical data is accelerated to be trained the coefficient of original acceleration control function, so as to being adjusted to coefficient so as to adjust and be Speed after the acceleration that several acceleration control functions is exported, which more approaches, accelerates the speed after preferably accelerating in empirical data, Regulation coefficient again afterwards, when accelerating control function and the matching of as far as possible more acceleration empirical datas training complete, obtain second Accelerate control function.

After the second acceleration control function is obtained, when controlling the treadbelt to accelerate, current speed, crest pressure value are obtained Number, accelerate control function using second, the number of present speed and crest pressure value is calculated, you can after obtaining acceleration Speed, by the speed of treadbelt be adjusted to accelerate after speed.

In step 503, when the number of crest pressure value is less than the second preset number, the treadbelt speed of treadmill is entered Row adjustment, so that treadbelt is slowed down.

When the number of crest pressure value is less than the second preset number, show that user's paces number in preset duration is less than Second preset number, cadence are slower, it is believed that user is gradually slowed down, then treadbelt can be controlled to slow down.Wherein, second is default Number is used to indicate the crest pressure value number at most counted in the preset duration of triggering treadbelt deceleration.Second preset number It can be the empirical value of acquiescence, can be set in advance in treadmill by developer.The setting up procedure of second preset number It is similar with the setting up procedure of the first preset number, it will not be described here.

The mode accelerated for control treadbelt, can obtain the present speed of treadbelt, right using the second deceleration control function The number of present speed and crest pressure value is calculated, the speed after being slowed down, after the speed of treadbelt is adjusted into deceleration Speed.Wherein, the second deceleration control function by present speed corresponding to mutual, crest pressure value number, slow down after Speed be fitted to obtain, fit procedure and above-mentioned fitting second accelerate the process of control function similar, will not be described here.

In step 504, when the number of crest pressure value is 0, control treadbelt stops.

When not getting crest pressure value in preset duration, show that user may be motionless in treadbelt and as treadbelt is slided OK, or treadbelt has been had been moved off, can has now controlled treadbelt to stop.

A kind of method that the present embodiment provides, there is provided mode for controlling treadbelt speed, ripple in preset duration can be counted The number of peak pressure force value, the cadence of user is known, to control the speed of treadbelt.This method only need to be according to the pressure value detected Treadbelt speed change is automatically controlled, without the limitation for the number of sensors that is under pressure, therefore reduces hardware cost and the sky occupied Between, the difficulty that design coordinates circuit and integrating process is reduced, and it is easy to maintain, reduce the general of treadmill failure Rate, improve the stability of treadmill.

Fig. 6 A are a kind of flow charts of treadbelt method for control speed according to an exemplary embodiment, such as Fig. 6 A institutes Show, the executive agent of this method is treadmill, is comprised the following steps：

In step 601, will be current when getting the crest pressure value of pressure sensor detection of treadmill configuration Time point is defined as first time point.

It is similar with above-mentioned steps 401 to obtain the process of crest pressure value, will not be described here.Due to crest pressure value and use The action that family falls foot is corresponding, gets when the first time point of crest pressure value can drop down onto treadbelt as user foot Time point.

It should be noted that the pressure sensor in the present embodiment can include first pressure sensor and second pressure passes Sensor, because two pressure sensors detect that the time point of crest pressure value is identical, therefore some pressure biography will be got The time point of sensor crest pressure value is defined as first time point.So, two pressure sensors can serve as mutually standby With equipment, when any one pressure sensor damages, the acquisition time of another pressure sensor crest pressure value is directly determined Point, it can't influence to control the accuracy of treadbelt rate process.

In step 602, will be current when getting the nominal pressure value of pressure sensor detection of treadmill configuration Time point was defined as the second time point.

Nominal pressure value is that user runs out of pressure sensor when foot during a step is located at calibration position and can detected Pressure value, the calibration position are a fixed position of treadbelt, and the distance of the calibration position and treadbelt front end is fixed demarcation Distance.When pressure sensor detects nominal pressure value, it may be determined that user foot is sitting at calibration position, gets mark Second time point of level pressure force value can be used as the time point that foot is located at calibration position.

Wherein, the nominal pressure value is the pressure value that first is 0 in a landing cycle, in other words in a landing Get that pressure sensor detects in cycle for the first time for 0 pressure value.Referring to Fig. 6 B, start to contact in the foot of user Treadbelt and during being moved rearwards with treadbelt, the pressure value that pressure sensor detects can be gradually reduced, when user foot In treadbelt during position corresponding with seam, the pressure value that pressure sensor detects drops to 0, that is, detects demarcation pressure Force value, user foot since position corresponding to seam in treadbelt as treadbelt is moved rearwards, the process until lifting foot In, the pressure value that pressure sensor detects is always 0.

During being moved rearwards due to user foot since position corresponding to seam, pressure that pressure sensor detects Force value is 0, in order to know that pressure sensor detects nominal pressure value in time, i.e., get for the first time be changed into 0 pressure Force value, the present embodiment can use each pressure value that calibration value probe algorithm detection pressure sensor detects：Work as pressure sensing When multiple pressure values that device detects include meeting the pressure value of the second preparatory condition, the pressure of the second preparatory condition will be met Value is used as nominal pressure value, and the current time is defined as into the second time point, and the second preparatory condition is that pressure value is 0 and upper one Pressure value is not 0.

The present embodiment can apply to foldable running apparatus, and the race plate of foldable running apparatus is divided into two by seam Point, and gathering can be folded in seam crossing and got up.The race of seam is not present in applied to non-folding treadmill or race plate During step machine, a certain position that can set treadbelt is calibration position, and ensures to fix by pressure value during the calibration position, by this Fixed pressure value is as nominal pressure value.For example, the process that a large number of users moves in treadbelt can be tested, it is determined that Go out the position that pressure value is fixed when some passes through in treadbelt, as calibration position.

In step 603, treadbelt is asked for from first time point to the displacement at the second time point.

The step specifically includes following steps 6031-6033：

In step 6031, each recording period between first time point and the second time point is determined.

In step 6032, treadbelt is obtained in the translational speed of each recording period, displacement is calculated.

Treadbelt actually can record current translational speed, and respective stored every a recording period in the process of running Recording period and translational speed.Treadmill is it is determined that first time point and after the second time point, it may be determined that the two when Between put between each recording period, obtain the translational speed of each recording period, calculated using below equation, obtained To displacement S (t1, t2).

M=(t2-t1)/t0；

Wherein, S (t1, t2) represents displacement, and j represents the mark of recording period, and t1 represents first time point, t2 tables Showed for the second time point, t0 represents the duration of recording period, and m represents the number of recording period, v_jRepresent treadbelt in record Between section j translational speed.

Because first time point is that foot drops down onto time point in treadbelt, the second time point was that foot is located at calibration position Time point, thus treadbelt from first time point to the displacement at the second time point be when foot falls where position and mark Positioning the distance between is put.

It should be noted that the translational speed of recording period refers to some record time point record in recording period Speed, the record time point can be the time terminating point or time starting point of recording period, naturally it is also possible to for record Some time point in period.By recording period when a length of 20ms exemplified by, it is assumed that in the time of each recording period Terminating point records current speed, then translational speed that can be using the speed that 20ms is recorded as the 1st recording period, and the Translational speed of the speed of 40ms records as the 2nd recording period, by that analogy.

In step 604, the difference of demarcation distance and displacement is calculated, is obtained between position and front end that foot falls Target range.

Referring to Fig. 6 C, the distance between position (that is, foothold position) fallen due to front end and foot (target away from From) and the distance between the position that falls of foot and calibration position (displacement) and value be demarcate with a distance from, therefore calculate During the difference of demarcation distance and displacement, obtained difference is to drop down onto target range when in treadbelt between front end.

In step 605, when target range is less than the first pre-determined distance, the treadbelt speed of treadmill is adjusted, So that treadbelt accelerates.

When target range is less than the first pre-determined distance, show nearer apart from front end when user foot is dropped down onto in treadbelt, use Family, in order to avoid user bumps against the console of front end, can adjust relative to treadbelt speed to the treadbelt speed of treadmill It is whole, so that treadbelt accelerates, to increase the distance of foot and front end when user falls foot.First pre-determined distance is used to indicate to trigger It the maximum for the target range that the treadbelt accelerates, can be the empirical value of acquiescence, or can manually be set by developer Put.

Process for setting first pre-determined distance, the process that user runs in treadbelt can be surveyed in advance Examination, is obtained when user accelerates, the target range of foot and front end when stopping over, by counting the target range of a large number of users, really The scope that the distance that sets the goal is generally fall into, the distance of maximum is chosen from the scope as the first pre-determined distance.

The process accelerated for control treadbelt, substantial amounts of acceleration empirical data, every acceleration experience number can be obtained in advance According to include mutually corresponding to speed after present speed, target range, acceleration, intended according to the acceleration empirical data of acquisition Close, obtain the 4th acceleration control function, the input of the 4th acceleration control function is present speed, target range, is exported to add Speed after speed.

Wherein, for the process being fitted, the original acceleration control function that coefficient is undetermined can be set, by substantial amounts of Empirical data is accelerated to be trained the coefficient of original acceleration control function, so as to being adjusted to coefficient so as to adjust and be Speed after the acceleration that several acceleration control functions is exported, which more approaches, accelerates the speed after preferably accelerating in empirical data, Regulation coefficient again afterwards, when accelerating control function and the matching of as far as possible more acceleration empirical datas training complete, obtain the 4th Accelerate control function.

After the 4th acceleration control function is obtained, when controlling the treadbelt to accelerate, current speed, target range are obtained, is adopted Accelerate control function with the 4th, present speed and target range are calculated, you can the speed after being accelerated, by treadbelt Speed is adjusted to the speed after accelerating.

In step 606, when target range is more than the second pre-determined distance, the treadbelt speed of treadmill is adjusted, So that treadbelt is slowed down.

When target range is more than the second pre-determined distance, determines that target range is larger, show that user foot is dropped down onto in treadbelt When apart from front end farther out, user is slower relative to treadbelt speed, in order to avoid user falls from treadbelt rear end, treadbelt can be controlled to subtract Speed, to reduce the distance of foot and front end when user stops over.Second pre-determined distance is used to indicate to trigger the mesh that the treadbelt is slowed down It the minimum value of subject distance, can be the empirical value of acquiescence, or manually be set by developer, second pre-determined distance is set Process with set the first pre-determined distance process it is similar, will not be described here.

The mode slowed down for control treadbelt, the present speed and target range of treadbelt can be obtained, is slowed down using the 4th Control function, present speed and target range are calculated, the speed after being slowed down, the speed of treadbelt is adjusted to slow down Speed afterwards, the 4th deceleration control function is by intending the speed after mutual corresponding present speed, target range, deceleration Conjunction obtains, and fit procedure accelerates control function similar with the 4th.

The method that the present embodiment provides, there is provided a kind of mode for controlling treadbelt speed, calibration position can be pre-set, During user runs, ask for treadbelt and be located at calibration position to foot from the first time point for getting crest pressure value The displacement at the second time point, calculate the target range that user foot drops down onto when in treadbelt and front end, so as to according to target away from From the speed of control treadbelt.This method only need to automatically control treadbelt speed change according to the pressure value detected, without being under pressure The limitation of number of sensors, therefore reduce the number of pressure sensor, so as to the space for reducing hardware cost He occupying, drop Low design coordinates the difficulty of circuit and integrating process, and easy to maintain, reduces the probability of treadmill failure, improves The stability of treadmill.

Fig. 7 is a kind of flow chart of treadbelt method for control speed according to an exemplary embodiment, as shown in fig. 7, The executive agent of this method is treadmill, is comprised the following steps：

In step 701, multiple pressure values that the pressure sensor of treadmill configuration detects are obtained.

When pressure sensor includes first pressure sensor and second pressure sensor, then obtain crest pressure value and refer to Obtain multiple pressure values that any one pressure sensor detects.

Specified number wherein it is possible to pre-set, obtain the pressure value specified number every time.Or it can also obtain Belong to multiple pressure values of special time period, specifically may comprise steps of 7011 or 7012.

In step 7011, the crest pressure value that pressure sensor detects is got at the 3rd time point, and afterwards The 4th time point when getting the trough pressure value that pressure sensor detects, obtain from the 3rd time point to the 4th time point The multiple pressure values detected.

For running the treadmill in plate in the absence of seam, the pressure value that its pressure sensor configured detects can go out The variation tendency of existing " crest pressure value-trough pressure value-crest pressure value ", it is changed into the mistake of trough pressure value from crest pressure value Journey corresponds to the landing cycle of user, then can work as and detect crest pressure value through detecting trough pressure again after a period of time During force value, each pressure value detected in section this period is obtained.

Specifically, when getting a crest pressure value at the 3rd time point, and obtained in the 4th period afterwards When getting a trough pressure value, it can determine that the 3rd time point collected to the 4th time point from the pressure value gathered Pressure value.

Wherein, the acquisition methods of crest pressure value are similar with above-mentioned steps 401, will not be described here.

For trough pressure value and the process of acquisition trough pressure value, trough pressure value is during user runs out of a step The pressure value that pressure sensor can detect when foot is left from treadbelt.The present embodiment can use valley value probe algorithm to detect Each pressure value that pressure sensor detects：Whenever the pressure value of pressure sensor is collected, by the pressure value and upper one The secondary pressure value collected is compared, can be with when the pressure value that this is collected is bigger than the pressure value that collects of last time Know that pressure value is in ascendant trend, can be with when the pressure value that this is collected is smaller than the pressure value that collects of last time Know that pressure value is in downward trend.

So, if the pressure value before some pressure value is in downward trend, and pressure value is in after the pressure value Ascendant trend, then can be using the pressure value as trough pressure value.With reference to the design, the present embodiment is provided with the 3rd preparatory condition, When multiple pressure values that pressure sensor detects include meeting the pressure value of the 3rd preparatory condition, the 3rd will be met and preset The pressure value of condition as trough pressure value, wherein, the 3rd preparatory condition is that pressure value is less than a upper pressure value and under being less than One pressure value.

Further, it is contemplated that multiple pressure values before can also working as some pressure value are continuously in downward trend, and Pressure value is in ascendant trend after the pressure value, then using the pressure value as trough pressure value.Correspondingly, the 3rd default article Multiple pressure values before part could be arranged to pressure value are successively decreased successively, and pressure value is less than next pressure value, the plurality of pressure The number of force value can determine according to the actual requirements.

In a kind of possible implementation, for the ease of storing and recording trough pressure value, treadmill can establish ripple Paddy queue, and each trough pressure value got is stored in trough queue, then trough queue can be used for record pressure Multiple trough pressure values that force snesor has been detected by, multiple trough pressure values in trough queue can be according to the acquisition time Point arranges from evening to the order of morning.So, when getting current trough pressure value, the trough pressure value that will can newly obtain Added to first of trough queue.

In step 7012, when the crest pressure value for pressure sensor is got at the 3rd time point detecting, and at it Rear the 5th time point get that pressure sensor detects for the first time for 0 pressure value when, obtain from the 3rd time point to Multiple pressure values that 5th time point detected.

Wherein, nominal pressure value is the pressure value that first is 0 in a landing cycle.The race of seam for running plate be present For step machine, because the pressure value that pressure sensor detects occurs " crest pressure value -0- is continuously 0- crests pressure value " Such circulation change, the process that the pressure value detected is changed into 0 from crest pressure value were corresponded in one of user landing cycle , then can be when detecting crest pressure value through examining after a period of time from the process for falling foot and being moved to position corresponding to seam When measuring pressure value and being changed into 0, each pressure value detected in section this period is obtained.

Wherein, whether judge currently to get is to get for the first time after the 3rd time point as 0 as 0 pressure value The method of pressure value refers to above-mentioned steps 602, will not be described here.

In a step 702, the pressure mean values of multiple pressure values are asked for.

In practical application, treadmill can every the pressure value that collection period collection pressure sensor detect, and Corresponding storage acquisition time section and corresponding pressure value.

It is corresponding with above-mentioned steps 7011, then, can be true when treadmill is it is determined that after the 3rd time point and four time points Each acquisition time section between the two fixed time points, obtains pressure value corresponding to each acquisition time section, using following public affairs Formula is calculated, and obtains pressure mean values W (t3, t4).

N=(t4-t3)/t0；

Wherein, W (t3, t4) represents pressure mean values, and i represents the mark of acquisition time section, and t3 represents the 3rd time point, t4 Represented for the 4th time point, t0 represents the duration of acquisition time section, and n represents the number of acquisition time section, w_iRepresent that treadbelt is gathering The pressure value that period i is collected.

It is corresponding with above-mentioned steps 7012, then, can be true when treadmill is it is determined that after the 3rd time point and five time points Each acquisition time section between the two fixed time points, obtains pressure value corresponding to each acquisition time section, using following public affairs Formula is calculated, and obtains pressure mean values W (t3, t5).

N=(t5-t3)/t0；

Wherein, W (t3, t5) represents pressure mean values, and i represents the mark of acquisition time section, and t3 represents the 3rd time point, t5 Represented for the 5th time point, t0 represents the duration of acquisition time section, and n represents the number of acquisition time section, w_iRepresent that treadbelt is gathering The pressure value that period i is collected.

In step 703, when pressure mean values are more than the first preset pressure value, the treadbelt speed of treadmill is adjusted It is whole, so that treadbelt accelerates.

First preset pressure value is used for the minimum value for indicating pressure mean values when triggering treadbelt accelerates.When multiple pressure are averaged When value is more than first preset pressure value, it is determined that the multiple pressure values detected are average larger, and because user distance pressure passes Sensor is more near, and the pressure value detected is generally bigger, then can determine that user foot and pressure sensor are closer to the distance, that is, use Family foot and front end are closer to the distance, then control treadbelt to accelerate, and first preset pressure value can be the empirical value of acquiescence, Huo Zheyou Developer is manually set.

On the set-up mode of first preset pressure value, the process that user runs in treadbelt can be surveyed in advance Examination, it is corresponding with above-mentioned steps 7011, obtain when the position and nearer front end that user foot falls, foot moves from the position fallen The multiple pressure values detected during moving to the position lifted, pressure mean values are calculated, by the pressure for counting a large number of users Power average value, the scope that pressure mean values are generally fall into is determined, the pressure mean values of minimum are chosen from the scope as first Preset pressure value.Or it is corresponding with above-mentioned steps 7012, obtain when the position and nearer front end that user foot falls, foot The multiple pressure values detected during being moved to calibration position from the position fallen, pressure mean values are calculated, pass through statistics The pressure mean values of a large number of users, the scope that pressure mean values are generally fall into is determined, the pressure that minimum is chosen from the scope is put down Average is as the first preset pressure value.

The mode accelerated for control treadbelt, substantial amounts of acceleration empirical data, every acceleration experience number can be obtained in advance According to include mutually corresponding to speed after present speed, pressure mean values, acceleration, carried out according to the acceleration empirical data of acquisition Fitting, the 3rd acceleration control function is obtained, the input of the 3rd acceleration control function is present speed, pressure mean values, is exported For the speed after acceleration.

In step 704, when pressure mean values are less than the second preset pressure value, the treadbelt speed of treadmill is adjusted It is whole, so that treadbelt is slowed down.

Second preset pressure value is used for the maximum for indicating pressure mean values when triggering treadbelt is slowed down.When multiple pressure are averaged When value is less than second preset pressure value, it is determined that the multiple pressure values detected are averagely smaller, and because user distance pressure passes Sensor is more remote, and the pressure value detected is generally smaller, it is determined that user foot and pressure sensor are distant, i.e. user's pin Portion and front end are distant, then control treadbelt slow down, second preset pressure value can be acquiescence empirical value, setting up procedure with The setting up procedure of first preset pressure value is similar, will not be described here.

The mode slowed down for control treadbelt, present speed, the pressure mean values of treadbelt can be obtained, are slowed down using the 3rd Control function, present speed and pressure mean values are calculated, the speed after being slowed down, the speed of treadbelt is adjusted to subtract Speed after speed, the 3rd deceleration control function to the speed after mutual corresponding present speed, pressure mean values, deceleration by entering Row fitting obtains, and fit procedure accelerates control function similar with the 3rd.

In step 705, when pressure mean values are less than three preset pressure values, control treadbelt stops.

3rd preset pressure value is used for the maximum for indicating the pressure mean values that triggering treadbelt stops, the 3rd default pressure Force value is less than the second preset pressure value, when pressure mean values are less than three preset pressure values, can know pressure mean values It is very small, in fact it could happen that the abnormal conditions such as user leaves treadbelt, pressure sensor breaks down, then treadbelt to be controlled to stop.

A kind of method that the present embodiment provides, there is provided mode for controlling treadbelt speed, pressure sensor inspection can be asked for The pressure mean values of the multiple pressure values measured, the speed of treadbelt is controlled according to pressure mean values, this method only need to be according to detection To pressure value automatically control treadbelt speed change, without the limitation for the number of sensors that is under pressure, therefore reduce pressure sensing The number of device, so as to the space for reducing hardware cost He occupying, the difficulty that design coordinates circuit and integrating process is reduced, and And it is easy to maintain, the probability of treadmill failure is reduced, improves the stability of treadmill.
