Embodiment 1
Intelligent bracelet includes processor and function sensor, and function sensor includes heart rate sensor, blood pressure sensor, blood
One or more in lambda sensor, EGC sensor, the Intelligent bracelet further includes pressure sensor 101(for example attached
Shown in Fig. 1).
The measurement data of pressure sensor can reflect the tightness that Intelligent bracelet is worn, and can also reflect Intelligent bracelet
Whether correctly wear.Judging whether user correctly wears in Intelligent bracelet:
Firstly, producer Intelligent bracelet dispatch from the factory when, by function sensor measure data (such as heart rate value, blood oxygen levels, blood pressure
Value or electrocardio value) it is compared with the data of medical measurement, obtain the number of the data and medical measurement when function sensor measurement
According to numerical value closest to when, it is believed that user wears correct, and user is worn correct state and is denoted as state A by we, it is assumed that at this time
The numerical value F of pressure sensor0, numerical value F0It reacts user to wear correctly, that is, is in state A.
Or in addition, various parameters for human body, such as heart rate, blood pressure or electrocardio value, certain parameters medically permit having
Perhaps parameter itself allows the presence of part deviation deviation not will lead to guide people body exercise guidance or life to part measured deviation
The mistake of guidance living is obtaining the correct numerical value F of above-mentioned pressure sensor user wearing for such parameter0Afterwards, according to medicine
Tolerance, according to test obtain function sensor measured value permission deviation delta F0, i.e., when the measurement of pressure sensor
Numerical value be [F0-ΔF0, F0+ΔF0] when, it is also believed that user is in state A.
Secondly, in the method for instructing user correctly to wear Intelligent bracelet, also according to the number measured function sensor
According to being judged.For being medically impermissible for parameter devious, as numerical value F < F of pressure sensor actual measurement0When, place
Reason device judges to wear pine according to the result of the comparison, and processor can control display screen simultaneously and show " wearing pine ";Work as pressure
Numerical value F > F of force snesor actual measurement0When, processor judges to wear tension according to the result of the comparison, and processor can be same
When control display screen show " wearing tension ".And the parameter for medically admitting of part deviation, when pressure sensor reality
Numerical value F < F of measurement0-ΔF0When, processor judges to wear according to the result of the comparison pine, and processor can control simultaneously it is aobvious
Display screen shows " wearing pine ";As numerical value F > F of pressure sensor actual measurement0+ΔF0When, processor is according to the result of the comparison
Tension is worn in judgement, and processor can control display screen simultaneously and show " wearing tension ".By prompt, user can pass through tune
The watchband of whole Intelligent bracelet is able to conveniently find watchband length when user wears correct, to be adjusted to elastic suitable, energy correctly
Measure the state A of human parameters.
Embodiment 2
When on the basis of embodiment 1, using pressure sensor, since Intelligent bracelet is compared with the contact area of human body
Greatly, a pressure sensor is often not enough to determine whether user really wears correctly, therefore, it is necessary in Intelligent bracelet and people
Be arranged on the face of body skin contact multiple pressure sensor 101(attached drawings 2,3 and 4 respectively indicate tool there are two, three and four pressure
The case where force snesor).Multiple pressure sensor is preferably evenly arranged in around function sensor or is evenly arranged in intelligence
The surface of energy bracelet and skin contact.
By taking two pressure sensors as an example (such as attached drawing 2), it is denoted as left and right pressure sensor respectively, with 1 class of embodiment
Seemingly, judging whether user correctly wears in Intelligent bracelet:
Firstly, producer Intelligent bracelet dispatch from the factory when, by function sensor measure data (such as heart rate value, blood oxygen levels, blood pressure
Value or electrocardio value) it is compared with the data of medical measurement, obtain the number of the data and medical measurement when function sensor measurement
According to numerical value closest to when, it is believed that user wears correct, and user is worn correct state and is denoted as state A by we, it is assumed that at this time
The numerical value of left and right pressure sensor is respectively F01And F02, this two measurement numerical response users wear correct, that is, be in state
A。
Or in addition, various parameters for human body, such as heart rate, blood pressure or electrocardio value, certain parameters medically permit having
Perhaps parameter itself allows the presence of part deviation deviation not will lead to guide people body exercise guidance or life to part measured deviation
The mistake of guidance living is obtaining the correct numerical value F of above-mentioned pressure sensor user wearing for such parameter01And F02Afterwards, according to
According to the tolerance of medicine, the deviation delta F of the permission of function sensor measured value is obtained according to test01With Δ F02, i.e., when left pressure
The numerical value of the measurement of force snesor is [F01-ΔF01, F01+ΔF01] and right pressure sensor measurement numerical value be [F02-ΔF02,
F02+ΔF02] when, it is also believed that user is in state A.
Secondly, in the method for instructing user correctly to wear Intelligent bracelet, also according to the number measured function sensor
According to being judged.For being medically impermissible for parameter devious:
1) as the numerical value F of left pressure sensor actual measurement1< F01Or F1> F01When, no matter the reality of right pressure sensor
Measurement numerical value is how many, and processor judges that pine or left side wearing tension were worn in the left side of bracelet all in accordance with comparison result, and
Processor can control display screen simultaneously and show " wearing pine in the left side " or " left side wearing tension ".
2) as the numerical value F of right pressure sensor actual measurement2< F02Or F2> F02When, no matter the reality of left pressure sensor
Measurement numerical value is how many, and processor judges worn right pine or the worn right tension excessively of bracelet all in accordance with comparison result, and
Processor can control display screen simultaneously and show " worn right is excessively loose " or " worn right tension ".
Certainly, when the measurement numerical value of left pressure sensor and right pressure sensor is not correct numerical value, processor
The elastic of left and right side is judged simultaneously, and controllable display screen shows such as " wearing pine in the left side " and " worn right simultaneously
The prompt of tension ".
And the parameter for medically admitting of part deviation:
1) as the numerical value F of left pressure sensor actual measurement1< F01-ΔF01Or F1> F01+ΔF01When, no matter right pressure
The actual measurement numerical value of sensor is how many, and processor judges that pine or the left side were worn in the left side of bracelet all in accordance with comparison result
Tension is worn, and processor can control display screen simultaneously and show " wearing pine in the left side " or " left side wearing tension ".
2) as the numerical value F of right pressure sensor actual measurement2< F02-ΔF02Or F2> F02+ΔF02When, no matter left pressure
The actual measurement numerical value of sensor is how many, and processor judges worn right pine or the right excessively of bracelet all in accordance with comparison result
Tension is worn, and processor can control display screen simultaneously and show " worn right is excessively loose " or " worn right tension ".
Certainly, when the measurement numerical value of left pressure sensor and right pressure sensor is not to fall in range ([F01-Δ
F01, F01+ΔF01] and [F02-ΔF02, F02+ΔF02]) numerical value when, processor simultaneously judges the elastic of left and right side,
And controllable display screen shows the prompt such as " wearing pine in the left side " and " worn right tension " simultaneously.
User can indicate that (or prompt) knows whether correctly wear when wearing bracelet according to the wearing of bracelet as a result,
(be in state A), further progress are correctly adjusted to level off to state A.
Embodiment 3
On the basis of above-described embodiment 1, user can be corrected the Intelligent bracelet that do not wear correctly according to prompt,
Each function sensor of Intelligent bracelet is enabled more accurately to measure the parameter of human body.
In actual use, correctly wearing (above-mentioned state A) may insure each function sensing of Intelligent bracelet
Device can more accurately measure the parameter of human body, and still, the state A that " should correctly wear " is not but the most comfortable wearing shape of user
State.Correct wear is a kind of universal state, and still, each user is individual, individual wrist, skin to Intelligent bracelet
Wearing there is selectivity, briefly, be capable of measuring accurate state A probably and be not the wearing state that user likes, I
The wearing state of liking user be denoted as state B.Remove to obtain accurately measurement numerical value when user is forced to correct to state A
When, good wearing experience can be lost, therefore, it is necessary to be modified to the measurement data at state B, although so that
Under state B, the accuracy of the still available data measured such as function sensor each at state A.In this regard, proposing such as
The lower modified method of Intelligent bracelet sensor measurement:
Producer compares the data of the data of function sensor measurement and medical measurement when Intelligent bracelet is dispatched from the factory,
Obtain the numerical value of the data when the data of function sensor measurement and medical measurement closest to when, it is believed that user wear it is correct, I
User worn correct state be denoted as state A, it is assumed that the numerical value F of pressure sensor at this time0, numerical value F0User is reacted to wear
It wears correctly, that is, is in state A.
When the pressure value F of pressure sensor actual measurement is not equal to F0, the heart rate value of heart rate sensor measurement is (herein with function
For heart rate sensor in energy sensor) N, the heart rate data of human medical measurement is N0, N at this time0With N numerically not phase
Deng the problem for the measurement data inaccuracy at state B that reflects user that this is unequal.
As shown in Fig. 5, in the pressure limit [F that heart rate value can be detectedmin, Fmax] in (wherein FminAnd FmaxFor that can examine
The minimum pressure and maximum pressure of effective heart rate value are measured, F is lower thanminOr it is higher than FmaxHeart rate value without reference significance), pass through
Test measurement describes the relationship between Δ N and Δ F, and (Δ N is actual measured value N and Intelligent bracelet show value NsBetween difference,
ΔN=N- Ns, NsThe heart rate value shown for revised Intelligent bracelet).Description method can be measurement point value, and then fitting is bent
Line obtains function curve Δ N=g(Δ F of the Δ N about Δ F).
When pressure sensor measurement obtains numerical value F, processor calculates the pressure F under state A0(F0For Intelligent bracelet factory
When the parameter that identifies, each Intelligent bracelet has fixed F0) with difference DELTA F=F- F of F0, according to above-mentioned function curve Δ N
=g(Δ F) and obtained N value is measured, according to Δ N=N- NsCalculate Ns, by the NsValue show on a display screen as repairing
The numerical value that numerical value after just, i.e. user can be seen.
As a result, when the measurement numerical value of pressure sensor is in [Fmin, Fmax] in range when, even if user for comfort or
Other reasons fail for Intelligent bracelet to be worn on correct status (i.e. state A), pass through the feedback of pressure sensor and processor
Operation, the numerical value of the still available accurate function sensor of user.
It is similar, available by the means and curve matching of test when pressure sensor has 2:
Δ N=h(Δ F1, Δ F2), wherein Δ F1Pass through the actual measured value F and left pressure sensing for left pressure sensor
The bracelet factory guide data F of device01Between difference DELTA F1=F- F01, wherein Δ F2Pass through the practical survey for right pressure sensor
The bracelet of magnitude F and right pressure sensor factory guide data F02Between difference DELTA F2=F- F02。
Further, when pressure sensor have it is N number of when, pass through the available Δ N=h of the means and curve matching of test
(Δ F1, Δ F2... ..., Δ Fn).
