Detailed Description
The embodiment is a sports shoe for measuring body fat by adopting four electrodes, wherein two electrodes are used for generating exciting electrodes of exciting signals, the other two electrodes are used for measuring detection electrodes of voltage, sinusoidal exciting signals are generated by the exciting electrodes and are respectively applied to two feet of a human body, and then the other two electrodes are respectively used for collecting voltage on the two feet. A group of exciting electrodes and a group of detecting electrodes are respectively arranged on the left shoe and the right shoe, each shoe generates a sinusoidal exciting signal through the exciting electrodes and is added on the foot of a human body, the detecting electrodes collect voltage to measure the human body impedance, and the human body impedance is calculated through an algorithm. In the aspect of shape design, the whole system is miniaturized and integrated in a sports shoe, so that a user can carry the shoe conveniently. The sports shoe of the embodiment comprises a vamp 15, an insole 4 and a sole 7, wherein the insole 4 and the sole 7 are structurally shown in fig. 1, a positive electrode 2 and a negative electrode 8 are arranged on the upper surface of the insole 4, a main controller 6 and a battery 1 are arranged between the insole 4 and the sole 7, the main controller 6 can obtain human body impedance through measurement of a circuit consisting of the positive electrode 2, a human body and the negative electrode 8, calculate body fat of the human body according to the impedance and send the body fat data to a user for checking. As shown in fig. 2, the main controller 6 includes an MSP430F5528 microcontroller 11, and the MSP430F5528 microcontroller integrates a plurality of analog circuits, digital circuit modules and microprocessors with different functions on one chip, and has a small power consumption and a Mixed Signal Processor (Mixed Signal Processor) with a Reduced Instruction Set (RISC). The AFE4300 body fat measurement module 12 with TI is selected at the front end of the physical fitness test, and is connected with the MSP430F5528 microcontroller 11, so that body weight and Body Composition Measurement (BCM) can be performed. The AFE4300 is a simple, easy-to-use, high-precision, low-power consumption front-end solution, and can help engineers design a weight meter including a body composition measuring instrument, a body impedance analyzer, and an impedance measuring device, which can speed up the marketing process of products compared to the existing complex multi-chip solution. AFE4300 can measure the impedance from hand to hand, foot to foot, and even from hand to foot, i.e., between any two branches of a human limb. First, it generates a sine wave to excite the body, applies the sine wave to two measurement points, and since the sine wave is an alternating signal, its impedance is different according to the body composition (body fat). And the other channel can sample and analyze the human body impedance (which is not in a pure resistance form, and also comprises an inductor and a capacitor, and is actually a composite impedance), and the I and Q signals are obtained through IQ separation and filtering in a chip and certain digital operation, so that the impedance between two measurement points is obtained, and the human body components can be reflected to a certain degree. The measurement of the front end of the body composition is relatively complex and includes quadrupole measurement techniques and complex impedance measurement techniques. AFE4300 digitizes the impedance of the human body, and IQ separates, the subsequent work is handed to MCU to process. The AFE4300 integrates two separate signal chains, one for weight measurement and the other for body composition analysis, multiplexed using a 16bit 860S/S analog-to-digital converter (ADC). The main controller 6 further comprises a crystal oscillator circuit 9 and a CC2541 Bluetooth module 10 which are connected with the microcontroller 11, the crystal oscillator circuit 9 is used for generating synchronous signals, and the Bluetooth module 10 sends body fat data to devices such as a mobile phone and a computer, so that a user can check the body fat data conveniently. As shown in fig. 3, a charging port 13 is provided on the side of the upper for the convenience of the user, and a dust-proof and water-proof cover 14 is provided on the charging port to prevent the charging port from contacting muddy water and other dust and dirt. In order to meet the daily walking requirement, the outer surface of the insole 4 is provided with a drain hole 3, and the sole 7 is adhered with a non-slip mat 5. The battery 1 is powered by a high-performance storage battery, the system can continuously work for more than 10 days without charging, and the power supply voltage is 3.5-5V.
The specific working process is that,
when the shoe is used, a user firstly wears the sneaker to enable the front sole and the rear sole to respectively contact the middle positive electrode 2 and the negative electrode 8. The positive electrode 2 and the negative electrode 8 form a circuit through the human body due to the human body having conductivity. The AFE4300 front-end on the master controller 6 sends out two separate signal chains, one for the Weight Scale (WS) measurement and the other for the Body Composition Measurement (BCM) analysis. A 16-bit 860SPS analog-to-digital converter (ADC) is multiplexed between the two signal chains. The weight measurement signal chain comprises an instrumentation amplifier (INA) with gain set by an external resistor followed by a 6-bit digital-to-analog converter (DAC) for offset correction, and a circuit driving an external bridge/load cell (with a fixed voltage of 1.7V for proportional measurements). The other channel of the AFE4300 measures the body composition by generating a sinusoidal current into the body. This sinusoidal current is generated by an internal pattern generator and a 6-bit, 1MSPS DAC. A voltage to current converter applies this sinusoidal current to the body between the two terminals. The voltage generated at these two terminals is generated by the impedance of the human body, this voltage is measured by a differential amplifier, rectified and its amplitude is extracted and measured by a 16-bit ADC. Since a sine wave is an alternating signal, its impedance varies with body composition (body fat). The impedance of the human body sampled and analyzed by the previous channel (which is not in a pure resistance form, and also comprises an inductor and a capacitor, and is actually a composite impedance) is subjected to IQ separation and filtering in a chip, and then I and Q signals are obtained through certain digital operation, so that the impedance between two measurement points is obtained, and the human body components can be reflected to a certain degree. A digital-to-analog converter (ADC) of the AFE4300 converts the obtained I and Q signals into digital signals, and sends the digital signals to an MSP430F5528 microcontroller for processing, and the MSP430F5528 microcontroller obtains various data of the human body through calculation. Then the data is sent to the TI CC2541 Bluetooth module, and the TI CC2541 Bluetooth module sends the data to the mobile phone of the user, so that the user can check the data conveniently.
