This initial digital signal 29 is corrected by control unit 26, it is thus achieved that a correcting digital signal 28, and
This correcting digital signal 28 and the reference digital signal pre-set are compared and judges user's whether mistake
Degree is satiated with food.This reference digital signal pre-set to should user have dinner time acceptable waistline length
Reference value, this waistline length reference value can be a scope, it is also possible to be a concrete numerical value.
If the deviation of this correcting digital signal 28 and the reference digital signal pre-set is more than presetting
Term of reference, then micro-control unit 26 judges this user's overeating.Specifically, described microcontroller
This correcting digital signal 28 is converted into waistline length detected value by unit 26, if this waistline length detection
Value is more than the above-mentioned waistline length reference value pre-set, then micro-control unit 26 judges that this user is the fullest
Food, and transmit alarm command to described control unit 27.Described control unit 27 is defeated according to this alarm command
Go out warning message, call user's attention.User can close described first sensing unit 51, and stops drink
Food.
Needing further exist for explanation, (the i.e. first sensing is single to have employed two sensing units in the present embodiment
Unit 51 and second sensing unit 52), it is used for detecting user's whether overeating.Wherein, the second sensing is single
The length varying value of the second ring part 7 that unit 52 detects is mainly used in eliminating the first sensing unit 51
Detection error so that the testing result of the first sensing unit 51 is the most accurate.In other embodiments, also
Can be only with a sensing unit, the i.e. first sensing unit 51.In such cases, single with the second sensing
The second ring part the 7, second free end 70 and the second ring-type element 41 and second that unit 52 is combined together
Clamping part 42 parts such as grade all can be save, and does not repeats them here.
With reference to shown in Fig. 9, Fig. 9 is the flow chart of overeating detection method of the present invention.
Step S61, when being worn on the first annular portion 6 of scalability strap 1 of human body and sliding, institute
It is built-in that the sliding contact portion (14,17) in the first sensing unit 51 that states detects described first annular portion 6
The pulling force that non-telescoping property stripes 10 produces.Wherein, described first sensing unit 51 is arranged at first
On ring part 6.
Step S62, the revolving coil 25 within described first sensing unit 51 and fixed coil 24 basis
The tension variations value that described sliding contact portion (14,17) receives produces electromagnetic induction, and output voltage values
The first resistance 22 to the testing circuit 40 within described first sensing unit 51.
Step S63, the digital to analog converter 34 in described testing circuit 40 is by described first resistance 22
Magnitude of voltage (range size [0, Vref]) is converted into initial digital signal 29, and wherein, Vref is microcontroller
The voltage of the voltage output end output of unit 26.
Step S64, this initial digital signal 29 is entered by the micro-control unit 26 in described testing circuit 40
Row correction a, it is thus achieved that correcting digital signal 28.
Step S65, described micro-control unit 26 is by this correcting digital signal 28 and the reference number pre-set
Word signal compares to judge user's whether overeating.The reference digital signal that this pre-sets is corresponding
Acceptable waistline length reference value when this user has dinner, this waistline length reference value can be a model
Enclose, it is also possible to be a concrete numerical value.
In the present embodiment, user can be by the button 11 arranged on the first sensing unit 51 and rotation
Portion 12 pre-sets waistline length minima (the diet state of corresponding 0%), and by described control unit
27 pre-set waistline length maximum (fed state of corresponding 100%).Further, user is permissible
Pre-set waistline length reference value by described control unit 27, in the present embodiment, waistline is set
Length reference value is the special ratios (such as 60%-80%) of described waistline length maximum.
Step S66, if it is decided that this user's overeating, the most described micro-control unit 26 transmits warning and refers to
Making to a control unit 27, described control unit 27 exports warning message according to this alarm command.Described
Control unit 27 is arranged in described scalability strap 1.Specifically, if this correction numeral is believed
Numbers 28 with the deviation of the reference digital signal pre-set more than term of reference set in advance, then microcontroller
Unit 26 judges this user's overeating.In the present embodiment, described micro-control unit 26 is by this correction
Digital signal 28 is converted into waistline length detected value, if this waistline length detected value sets in advance more than above-mentioned
The waistline length reference value put, then micro-control unit 26 judges this user's overeating.
Further, the detection error that when having dinner to eliminate, human body respiration brings, in other embodiments,
Can also increase a sensing unit, the i.e. second sensing unit 52, this second sensing unit 52 is arranged at position
On second ring part 7 of body chest positions, when being used for detecting human body respiration, chest measurement length is pre-first
If the changing value of (in 10 seconds) in the time, to obtain chest measurement length first offset.Described
Described waistline length detected value, according to chest measurement length the first offset obtained, is carried out by one sensing unit 51
Compensate, it is thus achieved that waistline length first corrected value.For example, described waistline length the first corrected value
Described chest measurement length the first offset can be deducted equal to described waistline length detected value.
Further, in order to eliminate have dinner time other irregular actions of human body (as turned round with being sitting in below
People's speech or stand up to take from oneself plate farther out) the detection error brought, it is possible to use this is second years old
When sensing unit 52 detects human body respiration chest measurement length in the second Preset Time (in 30 seconds-60 seconds)
Changing value, to obtain chest measurement length second offset.Described first sensing unit 51 is according to acquisition
Chest measurement length the second offset, described waistline length detected value is compensated, it is thus achieved that a waist girth
Spend the second corrected value.For example, described waistline length the second corrected value can be equal to described waistline length
Detected value deducts described chest measurement length the second offset.
These are only the preferred embodiments of the present invention, not thereby limit the scope of the claims of the present invention, every
