Embodiment

In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, control is illustrated below The embodiment of the present invention.It should be evident that drawings in the following description are only some embodiments of the present invention, for For those of ordinary skill in the art, on the premise of not paying creative work, other can also be obtained according to these accompanying drawings Accompanying drawing, and obtain other embodiments.

To make only to schematically show part related to the present invention in simplified form, each figure, they are not represented Its as product practical structures.In addition, so that simplified form is readily appreciated, there is identical structure or function in some figures Part, only symbolically depicts one of those, or has only marked one of those.Herein, " one " is not only represented " only this ", can also represent the situation of " more than one ".

In one embodiment of the invention, as shown in figure 1, a kind of measuring method of Weight-detecting device, its feature exists In, including:

Step S100 obtains each (Weight-detecting device bottom) supporting part in vertical direction when receiving the first operation On acceleration magnitude;

Wherein, the first operation can be understood as the operation using Weight-detecting device, for example:Subscriber station is detected in body weight and filled Put and want to be weighed, or, it be have sent by mobile phone to Weight-detecting device using the operation such as request, and stand in body weight detection When on device.

Step S200 is not all located in the range of predetermined acceleration when the acceleration magnitude on the corresponding vertical direction of each supporting part When, (then thinking that Weight-detecting device is located at soft ground) controls the stretching structure in each described supporting part to stretch out;

Wherein, when the acceleration magnitude on the corresponding vertical direction of each supporting part is all located in the range of predetermined acceleration, survey Measure the weighing information of user.

Soft ground includes:It placed the ground of the flexible materials such as carpet, foamed plastics;Because Weight-detecting device is not direct Contacted with hard ground, its essence is be placed on soft ground (for example:Spread the floor of carpet) on, therefore, measurement result meeting There is certain error.Hard ground includes:The ground of the hard materials such as floor, concrete floor, ceramic tile.

Each supporting part can have a corresponding acceleration transducer, when subscriber station is on Weight-detecting device, lead to Acceleration transducer is crossed to obtain the acceleration magnitude on the corresponding vertical direction of each supporting part.

When support zone is in soft ground, subscriber station is on Weight-detecting device, when Weight-detecting device is by user Pressure when, soft ground can be to the power of the bounce-back of Weight-detecting device one, so that acceleration magnitude and body that supporting part is obtained The acceleration magnitude that re-detection device is obtained on hard ground is changed.

When support zone is in hard ground, the acceleration magnitude on the corresponding vertical direction of supporting part is exactly 9.8 (m/s2), In view of the error of each acceleration transducer, therefore, there is provided predetermined acceleration scope, for example:Error is ± 0.5, presets and adds Velocity interval can be 9.3-10.2, can include endpoint value.

When the acceleration magnitude on the corresponding vertical direction of each supporting part is located at this predetermined acceleration scope, illustrate each support Portion is all positioned on hard ground, therefore, there is no need to follow-up correction work, directly measures the weighing information of user i.e. Can.

When the acceleration magnitude on the corresponding vertical direction of each supporting part is not all located at this predetermined acceleration scope, illustrate to A rare supporting part, accordingly, it would be desirable to control the stretching structure of each supporting part to stretch out, is corrected in soft ground Work.

Step S300 obtains each supporting part and accelerated in the dynamic during stretching structure stretching on vertical direction Angle value;

Wherein, stretching structure stretching process refers to stretching structure since stretching, terminates to by the obstruction that can not be penetrated Dynamic acceleration value in this period continued stretching and maintain current stretching state.When dynamic acceleration value refers to this section The dynamic acceleration value of interior several acceleration magnitudes compositions, for example:Acceleration transducer measurement frequency is 50 times/second, and stretch knot The time that structure stretches out process is 0.5 second, then dynamic acceleration value is exactly to be made up of 25 acceleration magnitudes.

By the obstruction that can not be penetrated it is to be understood that for example:When Weight-detecting device is located on carpet, stretching structure will Carpet is penetrated, is directly contacted with floor, then the softer quality of carpet penetrates stretching structure, therefore stretching structure is stretched Go out process and do not include to terminate, and penetrate when encountering floor after carpet, stretching structure can not penetrate floor again, therefore, encounter behind floor Stretching process just finishes.Certainly, the material stretching structure of some soft grounds can not also may be penetrated, for example:Foamed plastics, Reason is:1) for fear of the volume of Weight-detecting device, stretching structure is not endless, possibly can not completely penetrate through foam plastic Material;2) consider that the part that stretching structure is contacted with soft ground may be only plane or have the problems such as not damaging floor The tip of rounding off, puncture ability is not very strong;Therefore, when encountering soft ground and can not also penetrate, it is also considered as stretching out Process terminates.

Step S400 performs corresponding behaviour according to the dynamic acceleration value on the corresponding vertical direction of each supporting part Make.

Wherein, dynamic acceleration value when encountering hard ground and dynamic acceleration value when encountering soft ground are to differ Sample, it therefore, it can judge whether to correct successfully by this, so as to perform follow-up corresponding operation.

Specifically, in the present embodiment, when user uses Weight-detecting device, can first judge Weight-detecting device whether position In soft ground, if if, stretching structure can be stretched out and perform correction, after judging whether to correct successfully, then performed corresponding Operation, it is ensured that the weighing information of user is that the corrected rear measurement of Weight-detecting device is obtained, and weighing information is more accurate, carries The high usage experience of user.

Preferably, step S400 includes:Step S410 works as the dynamic acceleration on the corresponding vertical direction of each supporting part When angle value all tends to and is stable in the range of the predetermined acceleration, (then think that Weight-detecting device has corrected that to finish, now Weight-detecting device is located at hard ground, therefore, it can) measure the weighing information for obtaining user.

Specifically, stretching structure is when piercing through soft ground, the acceleration magnitude on supporting part vertical direction is less than being located at Acceleration magnitude during hard ground, for example:It is worth on the basis of 9.3,9.3 can be less than when piercing through soft ground, it is in contact To hard ground, and after no longer stretching, acceleration magnitude on its vertical direction can be more than 9.3, and be stable at predetermined acceleration model In enclosing.

It therefore, it can confirm to be located at hard ground after whether it is corrected by judging the trend of dynamic acceleration value On, if it tends to and is stable at predetermined acceleration value scope, then it is assumed that it is corrected successfully, Current body mass detection means is located at hard On quality face, the weighing information of user can be measured.Weighing information includes:Body weight information.

In the present embodiment, judged whether to correct successfully according to the trend of dynamic acceleration value, only when correcting successfully, The weighing information of user is just measured, makes the accuracy for the weighing information that measurement obtains higher.

Preferably, the step S100 includes:Step S110 obtains the first acceleration of each supporting part in the horizontal direction Value;Also include after step S100:Step S500 is all located at presetting when the acceleration magnitude on the corresponding vertical direction of each supporting part When in acceleration range, according to the first acceleration magnitude in the corresponding horizontal direction of each supporting part, body weight detection dress is judged Put and whether be in horizontality;Step S520 is when the Weight-detecting device is in horizontality, and measurement obtains the title of user Measure information.

Specifically, by measuring static weight acceleration change, change of pitch angle is converted into, so that it is true to carry out horizontality Recognize.Special horizon sensor can be installed to measure the horizontality of Weight-detecting device, each supporting part can also be passed through On obtained the first acceleration magnitude of horizontal direction of acceleration transducer measurement, then data are handled, so as to carry out The judgement of horizontality.

Weight-detecting device is judged in horizontality, it is more accurate to ensure to measure obtained weighing information.

Preferably, also include between the step S500 and the step S520:Step S510 detects dress when the body weight Put when being not at horizontality, adjust the stretching structure in corresponding supporting part, be in the Weight-detecting device horizontal State.

Specifically, when Weight-detecting device is located at hard ground, body weight may be made due to the laying problem of hard ground Detection means is not at horizontality, accordingly, it would be desirable to stretch out corresponding stretching structure, raises the relatively low position of Weight-detecting device Put, so that Weight-detecting device is in horizontality, it is ensured that the accurate measurement for weighing information.

In other embodiments, in addition to same as described above, step S410 includes:Step S411 works as each supporting part When dynamic acceleration value on corresponding vertical direction all tends to and is stable in the range of the predetermined acceleration, each support is obtained The second acceleration magnitude of portion in the horizontal direction;Step S412 according to second in the corresponding horizontal direction of each supporting part plus Velocity amplitude, judges whether Weight-detecting device is in horizontality;Step S413 is not at level when the Weight-detecting device During state, the stretching structure in corresponding supporting part is adjusted, the Weight-detecting device is in horizontality;Step S414 works as When the Weight-detecting device is in horizontality, measurement obtains the weighing information of user.

Specifically, when stretching structure pierces through soft ground, when arriving to hard ground, having been completed Weight-detecting device pair The correction of the material on the ground of placement, further to the confirmation of its horizontality, it is ensured that the follow-up accuracy for weighing information.

When having judged that stretching structure arrives to hard ground, then obtain the of the current horizontal direction of each acceleration transducer Two acceleration magnitudes, can judge whether Weight-detecting device is located exactly with the second acceleration magnitude for ensureing the horizontal direction obtained In horizontality.

When weighing, the material on the ground not only placed to Weight-detecting device is corrected but also to Weight-detecting device Horizontality is corrected, it is ensured that the accuracy of the weighing information for the user that measurement is obtained, and improves the usage experience of user.

Preferably, step S400 includes:Step S420 is when dynamic on the corresponding vertical direction of at least one described supporting part When state acceleration magnitude tends to fluctuation status, (then thinking Weight-detecting device calibration failure, be still located at soft ground) sends prompting Information.

Specifically, when Weight-detecting device can not successfully pierce through soft ground (for example:Foam) when, during it stretches out Dynamic acceleration value can beat back and forth, and repeatedly be less than 9.3 (for example:Reference data is used as using 9.3), dynamic acceleration value is unstable It is fixed, in fluctuation status, and stretching structure stretch out during it is hindered when stopping and maintaining current stretching state because also It is to be in soft ground, its last acceleration magnitude will not be stable in the range of predetermined acceleration.

It therefore, it can be corrected into the problem of by the fluctuation status of dynamic acceleration value being confirmed whether to soft ground Work(, if unsuccessful, sends prompt message.Here prompt message can include:Voice message, information alert, light flash Prompting etc..

For example:Weight-detecting device voice broadcast " is in soft ground, measurement result may be caused inaccurate, please moved Weight-detecting device (Human fat balance) ";This prompt message can also be sent to background server by Weight-detecting device, allow backstage to take Business device is forwarded on the mobile phone of user (background server is connected with Weight-detecting device and mobile communication respectively), allows user to understand The present case of Weight-detecting device;Also sparkling feux rouges prompting user moves Weight-detecting device etc..

When Weight-detecting device can not ensure to weigh the accuracy of information because of extraneous factor, sending for prompt message can be with The problem of allowing the user to understand current in time, improves the usage experience of user.

Step S100 obtains the acceleration magnitude of each supporting part in the vertical direction when receiving the first operation;Step S100 includes:Step S110 obtains the first acceleration magnitude of each supporting part in the horizontal direction;

Step S200 is not all located in the range of predetermined acceleration when the acceleration magnitude on the corresponding vertical direction of each supporting part When, control the stretching structure in each supporting part to stretch out;

Step S300 obtains each supporting part and accelerated in the dynamic during stretching structure stretching on vertical direction Angle value;

Step S400 performs corresponding behaviour according to the dynamic acceleration value on the corresponding vertical direction of each supporting part Make;

Step S400 includes:

The dynamic acceleration value that step S410 works as on the corresponding vertical direction of each supporting part all tends to and is stable at institute When stating in the range of predetermined acceleration, measurement obtains the weighing information of user;Step S410 includes:Step S411 works as each support When dynamic acceleration value on the corresponding vertical direction in portion all tends to and is stable in the range of the predetermined acceleration, each is obtained The second acceleration magnitude of support part in the horizontal direction;Step S412 is according to second in the corresponding horizontal direction of each supporting part Acceleration magnitude, judges whether Weight-detecting device is in horizontality;Step S413 is not at water when the Weight-detecting device During level state, the stretching structure in corresponding supporting part is adjusted, the Weight-detecting device is in horizontality;Step S414 When the Weight-detecting device is in horizontality, measurement obtains the weighing information of user;

Step S420 tends to undulating when the dynamic acceleration value on the corresponding vertical direction of at least one described supporting part During state, prompt message is sent;

Step S500 when the acceleration magnitude on the corresponding vertical direction of each supporting part is all located in the range of predetermined acceleration, According to the first acceleration magnitude in the corresponding horizontal direction of each supporting part, judge Weight-detecting device whether in horizontal State;Step S510 adjusts the stretching structure in corresponding supporting part, made when the Weight-detecting device is not at horizontality The Weight-detecting device is in horizontality;Step S520 is measured when the Weight-detecting device is in horizontality To the weighing information of user.

Specifically, the state of ground that can be to its current placement when user uses Weight-detecting device in the present embodiment, water Level state is corrected, to ensure the accuracy for the weighing information that user's measurement is obtained;When correcting failure, prompting can be also sent Information, to remind user, improves the usage experience of user.
