a processing unit, configured to match the user name corresponding to the user, read the user characteristic information corresponding to the user name, and combine the current weight and the current impedance to calculate body fat information;

The processing unit reads the current body weight and the current impedance and the plurality of record analysis data sets to perform a calculation step, and the calculation step is performed by a formula: Dn=∣W-Wm∣*α+∣Z- Zm∣*β, where W is the current weight, Z is the current impedance, Wm And analyzing, for the plurality of records, a recorded weight in the data set, Zm is a recording impedance in the plurality of recording analysis data sets to obtain a plurality of distance values Dn, and the plurality of distance values are from a minimum value to The maximum value is sequentially arranged, and K is sequentially extracted from the minimum value of the plurality of distance values (K is a natural number greater than or equal to 1; the plurality of distance values, the K plurality of distance values are determined according to Performing a group operation on the corresponding user name of the plurality of record analysis data sets, and matching the user name corresponding to the largest grouping operation result with the user, and finally storing the current analysis data group in the The plurality of records in the storage unit analyze the data set.

Another example is a method for measuring body fat and a corresponding device [application number: CN00815691.3], including:

a step of energizing between two current electrodes disposed around an object, the electrode spacing being sufficiently shorter than the perimeter of the object;

And a step of calculating the amount of subcutaneous fat of the subject based on the first voltage.

The above two technical solutions all adopt the bioelectrical impedance analysis method to calculate the body fat content, and have the advantages of convenient use and simple manufacture, but the above schemes and other prior art body fat scales are all users installing related APP on the mobile phone, To obtain more accurate measurement data, it is generally necessary to input the user's height and other information in the App. The above two solutions cannot directly measure the user's height, and the user needs to manually input the height data, and then stand on the body fat scale to measure and pass. The body fat algorithm obtains information such as fat content, and has the following defects: the user's height cannot be automatically recognized. If the weight scale binder is not used by itself, it needs to re-bind the mobile phone or borrow the owner's mobile phone, which greatly reduces the extensive body fat scale. Sex and ease of use.
