If without the change of electric field, the most described controller judges that bracelet is in wearing state, and controller controls bracelet and keeps duty pattern;
If there being the change of electric field, the change of this electric field is transported to described controller by described touch passage B, described controller stores the distance value corresponding with electric field change amount, thus calculate the distance of bracelet reverse side and human body surface, bracelet reverse side and the distance range of user's skin surface when in described controller, pre-set user wears bracelet, described preset range at least includes appropriate distance, super distance and and do not wear distance, if the distance calculated is in above-mentioned appropriate distance, the most described controller judges that bracelet is in wearing state, controller controls bracelet and keeps duty pattern;If the distance calculated is in above-mentioned super distance, the most described controller judges that described bracelet is in from hands state, and described controller controls described touch display screen and shows " from hands ";Distance as calculated is in above-mentioned not to be worn in distance, and the most described controller judges that described bracelet is in from hands state, and the described controller described bracelet of control makes described bracelet in a dormant state;
Step 3: the touch passage B being positioned at bracelet reverse side 3 detects whether the change of electric field,
If nothing, the most described controller judges that bracelet is in from hands state, and described controller controls described bracelet makes described bracelet keep resting state;
If having, the change of this electric field is transported to described controller by described touch passage B, described controller stores the distance value corresponding with electric field change amount, thus calculate the distance of bracelet reverse side 3 and human body surface, bracelet reverse side 3 and the distance range of user's skin surface when in described controller, pre-set user wears bracelet, described preset range at least include appropriate distance, super distance and and do not wear distance, if the distance calculated is in above-mentioned appropriate distance, the most described controller judges that bracelet is in wearing state, and controller controls the in running order pattern of bracelet;If the distance calculated is in above-mentioned super distance, the most described controller judges that described bracelet is in the state of not worn, described controller controls described touch display screen and shows " not wearing ", and the most described controller controls vibrator vibration and/or the alarm equipment alarm of described bracelet;If the distance calculated is in and above-mentioned does not wears in distance, the most described controller judges that described bracelet is in from hands state, and described controller controls described bracelet makes described bracelet holding resting state.
Further, in above-mentioned steps two and/or step 3, if the distance calculated is in above-mentioned appropriate distance, described heart rate detector opened by the most described controller, described heart rate detector detects the HR values of the object closest with bracelet reverse side, if described HR values is in default user's HR values scope, then, judging that described bracelet is in wearing state, described bracelet opens duty pattern;If described HR values is not at above-mentioned default user's HR values scope, then judging that described bracelet is in from hands state, controller controls described bracelet and enters resting state.
Beneficial effect:
1) by above-mentioned technical scheme, the state " from hands state " can being in automatic decision bracelet, " wearing state " and " not wearing ", the state particularly " do not worn ", when bracelet is in the state do not worn, when each operational module of bracelet starts, measure the data drawn the most inaccurate, cause user that the health of oneself is produced erroneous judgement, thus bring serious consequence, the technical program can be while " from hands state " and " wearing state " judges, judge that whether bracelet is correctly wearing mode when wearing, based on this, user can be made to grasp the parameters of oneself health more accurately, it is of value to the reasonable adjusting of motion mode, bring healthy.
2) the touch passage of original bracelet is made modification by the present invention, do not change original parts, whether the characteristic of the electric field outside by human body skin is that human body judges to the environment residing for bracelet, need not start heart rate detector, can save substantial amounts of electricity in judge process.
Detailed description of the invention
It is described more fully with example embodiment referring now to accompanying drawing.But, example embodiment can be implemented in a variety of forms, and is not understood as limited to example set forth herein;On the contrary, it is provided that these embodiments make the present invention will more fully and completely, and the design of example embodiment is conveyed to those skilled in the art all sidedly.Accompanying drawing is only the schematic illustrations of the present invention, is not necessarily drawn to scale.Reference identical in figure represents same or similar part, thus will omit repetition thereof.
Additionally, described feature, structure or characteristic can be combined in one or more embodiment in any suitable manner.In the following description, it is provided that many details thus be given and embodiments of the present invention fully understood.It will be appreciated, however, by one skilled in the art that technical scheme can be put into practice and omit in described specific detail one or more, or other method, constituent element, device, step etc. can be used.In other cases, known features, method, device are not shown in detail or describe, realizes or operate avoiding that a presumptuous guest usurps the role of the host and each aspect of the present invention is thickened.
The schematic diagram of existing bracelet as shown in Figure 1, there is in gauge outfit 1 touch display screen 2, touch display screen 2 and be attached with three touches passage A, B and C, when controlling touch screen display content, when finger order is in time touching passage A, touch passage B and touch (the most from left to right slip) channel C, can realize touching the conversion from the first interface to second contact surface on display screen.When finger order is in time touching channel C, touch passage B and touch (slip the most from right to left) passage A, can realize touching the conversion from the 3rd interface to the 4th interface on display screen.Above-mentioned second contact surface can be the 3rd interface, it is also possible to be not the 3rd interface;4th interface can be the first interface, may not be the first interface, the i.e. left cunning of finger and right sliding movement (must sequentially touch above-mentioned three and touch passage) can realize the conversion at the interface of bracelet, certainly, can also be not limited to realize the function of the conversion at above-mentioned bracelet interface, other function can also be realized, as a left side slips off screen, right sliding lock screen etc..In accompanying drawing 1, being and touching display screen 2 reverse side 3 that is relative and that come close to or in contact with wrist shown in reference 3, is provided with heart rate detector 4 on reverse side 3.When opening heart rate detection module, heart rate detector 4 can start, detection user or the pulse of operator.The bracelet of the prior art described in accompanying drawing 1 is after the wearing, need artificial heart rate detection module or other the module of opening to realize corresponding function, when taking bracelet, also it is necessarily required to artificially close heart rate detection module or other module and reaches the function of power saving to close corresponding function;Or, the heart rate detection module of bracelet and other module are constantly in the state of unlatching, even if bracelet is not when wearing, still expend substantial amounts of electricity.
Defining " resting state " at this, resting state is to make to remove the state that remaining function (such as meter step, heart rate detecting function, sleep monitor, GPS positioning function, WIFI positioning function etc.) beyond bracelet time display function and range sensor function is all turned off.Definition " duty " is the state opening all functional modules that bracelet has.
On the basis of the existing bracelet of accompanying drawing 1, see shown in accompanying drawing 2, touch passage B by bracelet arranges heart rate detector 4 side of described reverse side, when controlling touch screen display content, when finger order is in time touching passage A and touch (the most from left to right slip) channel C, can realize touching the conversion from the first interface to second contact surface on display screen.When finger order is in time touching (sliding the most from right to left) channel C touch passage A, can realize touching the conversion from the 3rd interface to the 4th interface on display screen.Above-mentioned second contact surface can be the 3rd interface, it is also possible to be not the 3rd interface;4th interface can be the first interface, may not be the first interface, the i.e. left cunning of finger and right sliding movement (must sequentially touch above-mentioned two and touch passage A and C) can realize the conversion at the interface of bracelet, certainly, can also be not limited to realize the function of the conversion at above-mentioned bracelet interface, other function can also be realized, as a left side slips off screen, right sliding lock screen etc..That is, in the ITO of bracelet, three touch passages being saved one, original function yet suffers from, and the touch passage B touched three in passage is arranged in the reverse side 3 of bracelet, will not increase original power consumption and part.
When the reverse side 3 of described bracelet is when near human body, touch passage B and can sense the change of human body electric field, if without the change of electric field, illustrate that the close object of bracelet is not human body, judging that bracelet is in when hands state, controller controls described bracelet makes described bracelet in a dormant state;When there being the change of electric field, the change of this electric field is transported to described controller by described touch passage B, described controller stores the distance value corresponding with electric field change amount, thus calculate the distance of bracelet reverse side 3 and human body surface, bracelet reverse side 3 and the distance range of user's skin surface when in described controller, pre-set user wears bracelet, preset range at least includes appropriate distance (such as less than equal to 3mm), super distance (as (3,8] mm) and do not wear apart from (such as larger than 8mm);Described appropriate distance is that user is when rationally wearing bracelet, distance range between reverse side and user's skin of described bracelet, described super distance is that user is when the most rationally wearing or do not worn bracelet, distance between reverse side and user's skin of described bracelet more than described appropriate distance maximum and less than or equal to a certain threshold value (this threshold value can be when experimental stage can detect heart rate according to heart rate sensor heart rate sensor from the maximum distance of skin, can also be in experimental stage, when user has not worn described bracelet, bracelet reverse side distance skin maximum distance) distance range, the described distance do not worn between reverse side and the user's skin that distance is described bracelet is more than the distance range of above-mentioned threshold value.
As shown in Figure 3, it is judged that bracelet is as follows from the method for hands:
Step one: the state that controller detection bracelet is current, if the in running order pattern of bracelet, then proceeds to step 2, if bracelet is in a dormant state, then proceeds to step 3;
Step 2: the touch passage B being positioned at bracelet reverse side 3 detects whether the change of electric field,
If without the change of electric field, the most described controller judges that bracelet is in wearing state, and controller controls bracelet and keeps duty pattern;
If there being the change of electric field, the change of this electric field is transported to described controller by described touch passage B, described controller stores the distance value corresponding with electric field change amount, thus calculate the distance of bracelet reverse side 3 and human body surface, bracelet reverse side 3 and the distance range of user's skin surface when in described controller, pre-set user wears bracelet, described preset range at least includes appropriate distance, super distance and and do not wear distance, if the distance calculated is in above-mentioned appropriate distance, the most described controller judges that bracelet is in wearing state, controller controls bracelet and keeps duty pattern;If the distance calculated is in above-mentioned super distance, the most described controller judges that described bracelet is in from hands state, and described controller controls described touch display screen 2 and shows " from hands ";Distance as calculated is in above-mentioned not to be worn in distance, and the most described controller judges that described bracelet is in from hands state, and the described controller described bracelet of control makes described bracelet in a dormant state;
Step 3: the touch passage B being positioned at bracelet reverse side 3 detects whether the change of electric field,
If nothing, the most described controller judges that bracelet is in from hands state, and described controller controls described bracelet makes described bracelet keep resting state;
If having, the change of this electric field is transported to described controller by described touch passage B, described controller stores the distance value corresponding with electric field change amount, thus calculate the distance of bracelet reverse side 3 and human body surface, bracelet reverse side 3 and the distance range of user's skin surface when in described controller, pre-set user wears bracelet, described preset range at least include appropriate distance, super distance and and do not wear distance, if the distance calculated is in above-mentioned appropriate distance, the most described controller judges that bracelet is in wearing state, and controller controls the in running order pattern of bracelet;If the distance calculated is in above-mentioned super distance, the most described controller judges that described bracelet is in the state of not worn, described controller controls described touch display screen 2 and shows " not wearing ", and the most described controller controls vibrator vibration and/or the alarm equipment alarm of described bracelet;If the distance calculated is in and above-mentioned does not wears in distance, the most described controller judges that described bracelet is in from hands state, and described controller controls described bracelet makes described bracelet holding resting state.
Further, in above-mentioned steps two and step 3, if the distance calculated is in above-mentioned appropriate distance, described heart rate detector 4 opened by the most described controller, described heart rate detector 4 detects the HR values of the object closest with bracelet reverse side 3, if described HR values is in default user's HR values scope, then, judging that described bracelet is in wearing state, described bracelet opens duty pattern;If described HR values is not at above-mentioned default user's HR values scope, then judging that described bracelet is in from hands state, controller controls described bracelet and enters resting state.
By above-mentioned technical scheme, the state " from hands state " can being in automatic decision bracelet, " wearing state " and " not wearing ", the state particularly " do not worn ", when bracelet is in the state do not worn, when each operational module of bracelet starts, measure the data drawn the most inaccurate, cause user that the health of oneself is produced erroneous judgement, thus bring serious consequence, the technical program can be while " from hands state " and " wearing state " judges, judge that whether bracelet is correctly wearing mode when wearing, based on this, user can be made to grasp the parameters of oneself health more accurately, it is of value to the reasonable adjusting of motion mode, bring healthy.The touch passage of original bracelet is made modification by the present invention, do not change original parts, whether the characteristic of the electric field outside by human body skin is that human body judges to the environment residing for bracelet, need not start heart rate detector, can save substantial amounts of electricity in judge process.
