The tension variations value that contact portion (14,17) receives generates electromagnetic induction, and in output voltage values to first sensing unit 51
First resistor 22 in the detection circuit 40 in portion.
Step S63, digital analog converter 34 in the detection circuit 40 is by the voltage value (range in the first resistor 22
Size [0, Vref]) it is converted into initial digital signal 29, wherein and Vref is the electricity that the voltage output end of micro-control unit 26 exports
Pressure.
Step S64, the micro-control unit 26 in the detection circuit 40 are corrected the initial digital signal 29, obtain
One correcting digital signal 28.
Step S65, the micro-control unit 26 by the correcting digital signal 28 and pre-set reference digital signal into
Row compare judge user whether overeating.The pre-set reference digital signal, which corresponds to when the user has dinner, to be received
Waistline length reference value, which can be a range, is also possible to a specific value.
In the present embodiment, user can be set in advance by the button 11 and rotating part 12 being arranged on the first sensing unit 51
It sets waistline length minimum value (corresponding 0% diet state), and waistline length maximum is preset by described control unit 27
Value (corresponding 100% fed state).Further, user can preset waistline length ginseng by described control unit 27
Value is examined, in the present embodiment, setting waistline length reference value is special ratios (such as 60%- of the waistline length maximum value
80%).
Step S66, if it is decided that user's overeating, then the micro-control unit 26 transmits alarm command to a control
Unit 27 processed, described control unit 27 export warning message according to the alarm command.Described control unit 27 be set to it is described can
In retractility strap 1.Specifically, if the deviation of the correcting digital signal 28 and pre-set reference digital signal is big
In preset term of reference, then micro-control unit 26 determines user's overeating.In the present embodiment, the microcontroller
The correcting digital signal 28 is converted into waistline length detected value by unit 26, if the waistline length detected value is preparatory greater than above-mentioned
The waistline length reference value of setting, then micro-control unit 26 determines user's overeating.
Further, human body respiration bring detection error when having dinner to eliminate can also increase in other embodiments
Add a sensing unit, i.e. the second sensing unit 52, which is set to second positioned at body chest positions
On ring part 7, changing value of the bust length in the first preset time (in such as 10 seconds) when for detecting human body respiration, to obtain
One the first offset of bust length.First sensing unit 51 is according to the first offset of bust length of acquisition, to described
Waistline length detected value compensates, and obtains first corrected value of waistline length.For example, first school of waistline length
Positive value can be equal to the waistline length detected value and subtract first offset of bust length.
Further, other irregular movements of human body when having dinner to eliminate (such as turn round be sitting in subsequent people speech or
Person stands up to take from oneself farther away plate) bring detection error, it can use second sensing unit 52 detecting human body and exhale
Changing value of the bust length in the second preset time (in such as -60 seconds 30 seconds) when suction is mended with obtaining a bust length second
Repay value.First sensing unit 51 carries out the waistline length detected value according to the second offset of bust length of acquisition
Compensation, obtains second corrected value of waistline length.For example, second corrected value of waistline length can be equal to the waist
Girth degree detected value subtracts second offset of bust length.
The above is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalent structure made by bright specification and accompanying drawing content or equivalent function transformation, are applied directly or indirectly in other relevant skills
Art field, is included within the scope of the present invention.
