The present invention will be described for embodiment shown in reference to the accompanying drawings below.
As Fig. 1～shown in Figure 3, weighing scale has: the weight sensor 1 more than three; Calculation mechanism 2, it tries to achieve two-dimentional centre of gravity place according to the gravimetric value of being measured by described each weight sensor 1 by calculating; Indication mechanism 3, it shows the centre of gravity place of being tried to achieve by described calculation mechanism 2; Body weight display part 6, it shows examinee's body weight; And memory storage 5, it is made by semiconductor memory etc., storage is used for obtaining the calculating formula of centre of gravity place and the centre of gravity place of trying to achieve according to the measured value of weight sensor 1, as shown in Figures 2 and 3, in the present embodiment, has the mounting plate 71 of overlooking the shape that is rectangle (herein for roughly square shape), with across the backboard 72 of spatial configuration at mounting plate 71 downsides, below four bights of the described mounting plate 71 of overlooking the shape that is rectangle and between above the backboard 72, dispose weight sensor 1 respectively, and has the control part (not showing among the figure) that constitutes by CPU etc., its control: the obtaining of the gravimetric value of measuring by weight sensor 1, the instruction of in calculation mechanism 2, calculating, integral body such as instruction in the demonstration of indication mechanism 3.Moreover control part can also be also used as calculation mechanism 2.
And then, in the present embodiment, comprising: electrode 8, its sole on mounting plate 71 partly measured bio-impedance by mounting; There is not illustrated input mechanism, its input examinee's body data such as sex, age and height; Calculating part, it obtains body fat percentage (aforementioned calculation mechanism 2 also can dual-purpose) by calculating; And body fat percentage display part, it shows body fat percentage, above-mentioned memory storage 5 also stores the calculating formula that is used for calculating body fat percentage, calculation mechanism 2 is read in described calculating formula by memory storage 5, and body data substitution this calculating formula of bio-impedance of having measured and the examinee that is transfused to, thereby calculate body fat percentage, and show body fat percentage at the body fat percentage display part.
In calculation mechanism 2, obtaining in the gravimetric value that above-mentioned four weight sensors 1 are measured, read in the calculating formula that is used to obtain centre of gravity place from above-mentioned memory storage 5, and with each gravimetric value substitution calculating formula, the centre of gravity place of two dimension being tried to achieve in calculating.Weight sensor 1 is configured on the same plane perpendicular to vertical direction, in overlooking, this all is not aligned to a linearity, owing to carry out specific to the centre of gravity place on the described plane according to the gravimetric value of measuring by each weight sensor 1, therefore, if centre of gravity place X-Y coordinate then with the output of X, Y value; If the centre of gravity place polar coordinates then with distance center apart from the value of r and bias angle theta and export.Omitted concrete calculating formula, but can easily obtain according to balance of moment etc.
The examinee is when carrying out measured body weight, and the power switch (not marking especially among the figure) of opening weighing scale stands on the mounting plate 71, measures gravimetric value by four jiaos the weight sensor 1 of mounting plate 71, thereby detects examinee's body weight.Calculation mechanism 2 is read in the calculating formula (obtaining the formula of the total of the gravimetric value of being measured by each weight sensor 1) that is used to calculate body weight by storing mechanism 5, and each gravimetric value of substitution is calculated examinee's body weight and demonstrated body weight at body weight display part 6.And identical with the situation of calculating body weight, calculation mechanism 2 is read in the calculating formula that is used to obtain centre of gravity place by storing mechanism 5, thereby the gravimetric value of each weight sensor of substitution is calculated the coordinate (with reference to Fig. 4) of centre of gravity place.
The demonstration of centre of gravity place is on the basis of the coordinate of the centre of gravity place that calculates by described calculation mechanism 2, carries out corresponding to the demonstration (opening liquid crystal display in the present embodiment) of the unit 4 of the coordinate of the described centre of gravity place of indication mechanism 3 by unlatching.Calculating of measurement by weight sensor 1 and centre of gravity place carried out constantly, and to this, the demonstration of centre of gravity place can be carried out corresponding to calculating of centre of gravity place immediately, also can get the mean value of certain hour and shows at regular intervals.Fig. 5 is the two-dimensional coordinate figure that has marked and drawed the time variation of centre of gravity place, and actual is that the centre of gravity place every the small time is stored in memory storage 5, is not shown in indication mechanism 3, and shows in the plane for convenience.Then, thereby each centre of gravity place to certain hour averages the average coordinates of obtaining centre of gravity place on the time, shows this average coordinates at regular intervals on indication mechanism 3.The weight measurement of centre of gravity place, weight sensor owing to consider fluctuation in the true value at center, so adopt mean value to show, from rather than certain big centre of gravity place in a flash of deviation, and can show the value approximate with the true value of centre of gravity place.
In indication mechanism shown in Figure 13, unlatching is corresponding to the unit 4 of the coordinate of centre of gravity place and the demonstration of its inboard unit 4, and the demonstration of closing other whole unit 4, only open unit 4 corresponding to the coordinate of centre of gravity place yes feasible, as long as the unit 4 of centre of gravity place can be specific, then can control arbitrarily.
As shown in Figure 6,, as the X-Y coordinate system, directions X and Y direction waited respectively cut apart with the plane 31 of the demonstration usefulness of indication mechanism 3 in addition as other examples of indication mechanism 3, with a zone as a unit 4b.Even if this situation, with shown in Figure 1 go up example different just corresponding to the unit 4b of centre of gravity place, from identical with last example based on the process of the weight measurement of weight sensor 4 demonstration to the unit.
Also have, another example as indication mechanism 3, as shown in Figure 7, utilization is the zone that concentric a plurality of polygons (this example is a polygon-octagonal) at center are divided into a plurality of wide approximate ring-types with a bit, and utilize the straight line that is radially by described polygonal each angle from the point that becomes the center to be divided into a plurality of zones, to intersect to form a zone in described zone as a unit 4c, this situation is also identical with last example, and the process that begins to the unit 4 demonstration from the weight measurement based on weight sensor is identical with last example.
As mentioned above, by not being with point-like but utilizing unit 4 to show centre of gravity place with zone broader than point, thereby easier resolution centre of gravity place, even if there is not the common examinee of professional knowledge can be appreciated that at a glance yet, in addition, there is no need as the situation that shows centre of gravity place with point-like, will use the high device of exploring degree, thereby can reduce cost.
Next, other embodiment is described.The explanation of omission and above-mentioned embodiment same section, and different piece is described.
In the present embodiment, stand on the weighing scale, behind certain hour, begin to calculate and calculate centre of gravity place from the examinee.As shown in Figure 8, soon, though the movement of measured value has big fluctuation, through behind the certain hour, the fluctuation decay also restored calm, approaches true value after the examinee stood on the mounting plate 71.Therefore, by through beginning calculation after the certain time interval T and calculate centre of gravity place, thereby rock influence when getting rid of each single pin and standing on the weighing scale, can try to achieve the higher centre of gravity place of precision.Certain time interval T is determined by experience corresponding to weighing scale.
Also have, another kind of embodiment is described, present embodiment is after the examinee stands on the weighing scale, and the moment below the amplitude arrival certain value of weight sensor 1 begins to calculate and calculate centre of gravity place.Usually because the amplitude of the measured value of weight sensor 1 is to decay monotonously, as shown in Figure 9, so after below amplitude arrives certain value W, can not surpass this value again, amplitude approaches true value gradually when reducing.Therefore, after arriving below the certain value, begin to calculate and calculate centre of gravity place, thereby rock influence when getting rid of each single pin and standing on the weighing scale, can try to achieve the higher centre of gravity place of precision at the amplitude W of weight sensor 1.Amplitude W is determined by experience corresponding to weighing scale.
Also have, in above-mentioned any embodiment, also can store the coordinate of centre of gravity place in the past in advance and the centre of gravity place of measurement in real time is simultaneously displayed on the indication mechanism 3 at memory storage 5.The centre of gravity place of storage has been stored the centre of gravity place of trying to achieve according to the measurement in past, reads in the centre of gravity place of storage and is presented at indication mechanism 3 when measuring.Because the centre of gravity place that is necessary to distinguish centre of gravity place in the past and measures now so can prepare the demonstration look of multiple unit 4 in advance, makes the demonstration look difference of unit 4, perhaps light or the state difference of glimmering is distinguished by the lamp that makes demonstration.
Thus, the centre of gravity place in past and the centre of gravity place of measuring are now made comparisons, can easily hold the centre of gravity place dislocation and improve situations such as which kind of degree.
