However, the mode needs to be used for punching on the mounting plate, the problem of poor contact is easily caused by the punching mode, the measurement precision of the electronic scale is affected, and if the mounting plate is a glass panel, the problem of high punching failure rate exists, the cost is high, and the function expansion of the electronic scale is limited. In the embodiment of the application, the primary coil and the secondary coil are used as an electric signal transmission path, punching is not needed, a lead is not needed to be welded to an electrode plate, the cost is saved, and the influence on the detection precision is avoided. In addition, a lead does not need to be led out from the hole to connect the electrode plate, so that the possibility that the human body contacts the electrode plate to cause electrostatic breakdown damage to internal components can be eliminated. The coil of the body fat rate measuring device can be manufactured on the balance surface glass of the electronic scale by using the traditional wire winding process or an ITO film coating method. The coil can be placed at will to align with the scale body of the electronic scale, but the principle of aligning the primary coil and the secondary coil is to be ensured so as to ensure that the magnetic induction line can vertically pass through the coil during electromagnetic induction. The coil connected with the power supply is called a primary coil (also called a primary coil), and the coil connected with the load is called a secondary coil (also called a secondary coil).
In a possible implementation, it is understood that, in order to improve the signal transmission efficiency, the coil center may also be added with a magnetic core to improve the transmission efficiency, and specifically, a first magnetic core (not shown) may be disposed in the area surrounded by the first primary coil 31, and/or a second magnetic core (not shown) may be disposed in the area surrounded by the second secondary coil 42. It is understood that the purpose of measuring the body fat of the human body by the electromagnetic induction transmission of the signals between the coils is all included in the scheme.

It should be noted that, the body fat rate measured by the traditional bioelectrical impedance method has a certain requirement on the current frequency flowing through the human body, generally the current frequency is required to reach 5Khz or a multiple of 5Khz, if the current frequency has a deviation which may affect the measurement effect, but the body fat rate measuring device in the present application obtains the first voltage and the second voltage by the electromagnetic induction principle, and can further obtain the voltage difference between the first voltage and the second voltage, because the voltage difference is the voltage difference generated by connecting the human body with the first electrode plate 5 and the second electrode plate 6, the voltage difference can also be regarded as the voltage loss value caused by the human body, and the body fat rate of the human body can be calculated by taking the voltage loss value caused by the human body as the physical quantity, and no specific requirement on the electrical signal frequency exists, so that the measurement result is not affected by the current frequency, thereby effectively avoiding the disadvantages of the body fat rate measured by the traditional bioelectrical impedance method, the measurement accuracy is improved, and the measurement effect is ensured.
In order to better understand the technical solution in the embodiment of the present application, the derivation process of the voltage loss value is analyzed as follows:
if the first voltage input to the first primary coil by the signal generator 1 is UA, the number of turns of the first primary coil is NA, and the number of turns of the first secondary coil is NA.
The induced electromotive force generated by the first secondary coil is:
it should be noted that the induced electromotive force and the voltage can be converted to each other, and the conversion ratio is 1: 1.
If the voltage transmitted to the second primary coil is UB, the number of turns of the second primary coil is NB, and the number of turns of the second secondary coil is NB, the induced electromotive force generated by the second secondary coil is:
in the ideal case Ua is converted into a voltage value UB, so that the following relationship can be obtained:
if Na ═ NB and Na ═ NB are set for each coil turn, UA in an ideal state is the voltage converted from the induced electromotive force Ub of the second secondary coil.
In practical applications, the voltage converted by the induced electromotive force Ub of the second secondary coil is subtracted from the first voltage UA output by the signal transmitter to obtain a voltage loss value, and the voltage loss value is caused by the human body, so that the body fat percentage of the human body can be calculated based on the voltage loss value.
