Embodiment
Below in conjunction with accompanying drawing the utility model is described further
As shown in the figure, this multi-function watch (except that accurate timing, also has alarm clock function, date, month value and week value demonstration except that having clocking capability.It should be noted that this wrist-watch also has the millisecond meter function: 1. can start at any time, stop at any time; 2. stopwatch continues timing, and demonstration stops; 3. manual time-keeping is continuous, shows again, stops once more.Can be used for many people and participate in race, successively arrive, the accurate timing of a table), also have the function of measuring body fat mass in human body rate and moisture content rate; Its height, body weight, sex, age according to input calculate this body mass index (BMI), every day the amount of drinking water and every day heat consumption.In human body composition is measured, the surface metal frame of wrist-watch and the metal frame of bottom surface are two electrodes, compress watchcase with wearing table wrist and another palm, form closed circuit, measure human body impedance, in conjunction with 4 parameters (height, body weight, sex, age) of this human body input, utilization core mathematics model, by the control of MCU primary controller, combination, calculate this body fat rate and moisture rate.This technology should comprise: two electrodes that contact with human body left finesse (or right finesse), the right hand palm (or left hand palm); The signal input that is connected of two electrodes therewith, the testing circuit and the direct supply thereof of output; The human body impedance testing circuit; Data input circuit is promptly imported height, body weight, sex, age MCU peripheral circuit; The control of core mathematics model, resolving circuit; Make mistakes and warning circuit; Output circuit and display device.
The ultimate principle that this multi-function watch is measured human body composition fat percentage, moisture is: different human bodies, and its height, body weight difference, sex, age difference, the human body impedance difference causes human body composition value difference.According to human body impedance analytic approach and body mass index method and core mathematics model, can calculate fat percentage, the moisture rate of this human body; According to height, body weight, sex and the age of this human body input, adopt the formula of optimizing, can calculate this human body BMI index, every day the amount of drinking water and every day the heat consumption (see figure 1).In the human body impedance measuring equivalent electrical circuit: C, R1, R2, R3, BG1, BG2 and BG3 are known, and the output of four circuit, break-make, conversion, connection are controlled (see figure 3) by MCU.
Detection method
Put on wrist-watch (A point in the connection layout 3), the palm of another hand is pushed surperficial shell metal electrode (being the B point), press in the wrist-watch left side button three times with finger tip again, show for the first time body weight (P01 or P02), show for the second time height, show for the third time comprehensive " Hold ", show after 4 seconds " 0000 ", show through 4 seconds again and finish " End ".
Also can " End " back occur by four right down keys, then DISPLAY ORDER is opposite, is the fat percentage → heat consumption → every day every day amount of drinking water → BMI index → moisture rate.
If by not pressing tightly, or in two electrodes electrode loose contact is arranged, then show " Err ", expression makes mistakes, and no measurement result demonstration need compress resurveys.
The measuring and calculating principle:
The core mathematics model of measuring and calculating is to adopt organization system model and cell model, molecular model and atomic model to carry out the human body analysis, and these models are relevant with tested individual status.
The Different Organs of human body, different tissues, its electric conductivity difference.Big as water cut such as blood, cerebrospinal fluid, lymph liquid, sweat gland, gastric juice, intestinal juice, electric conductivity is good.Water cut such as muscle, nerve, liver, brain, kidney are also big, and electric conductivity might as well.And fat, bone, dry skin, electric conductivities such as connective tissue are relatively poor.Because electric conductivity has difference, specific conductance is different, and under identical voltage effect, its impedance also has difference, and interpersonal, owing to height, body weight, sex, the difference at age, its body impedance is also different.By switching, switching and the control of MCU to circuit, measure human body resistance, in conjunction with the core mathematics Model Calculation, draw human body composition fat percentage and moisture rate.
By a large amount of medical clinical data researchs, learn principle in conjunction with crowd's distribution statistics and set up unique index correction model and criterion scope.Because different human body composition electric conductivities there are differences,, can distinguish different component indexes in conjunction with the electronic technology design of optimizing.
BMI index, the every day amount of drinking water, every day, heat consumption calculated:
These three data are height, body weight, sex, the age numerical value according to tested person's input, adopt formula to be optimized and select to calculate.
Need to prove: through the human body composition data that this wrist-watch records, be not proposed as medical data,, take appropriate measures, improve fitness for the tested person only as the human body composition variation tendency.
