The heart rate electrocardiogram acquisition module mainly uses PPG photoelectricity volume sphygmographies to realize, principle is
The variation of volumetric blood is detected in living tissue by photoelectric reflection signal, then converts to obtain heart rate by software algorithm of heart rate
Data.It is more accurate for the acquisition of data if the absorptivity because of green light in Fig. 5 is the largest, so common LED green lights hair
Emitter is detected.When the light beam of certain wavelength is irradiated to user's skin surface, light beam will pass through the transmission and reflection of light
Mode is transmitted in photelectric receiver, and in entire blood circulation, skin and musculature are to maintain not the absorption of light
Become, because the bounce of heart causes the variation of pulse, the volumetric blood in skin and musculature to be also to change in fluctuation-type
, when the heart contracts, the volumetric blood in skin and musculature is maximum, and the absorptivity of light has reached maximum, so electrocardio
The luminous intensity that receiver detects is minimum.And when diastole, the volumetric blood in skin and musculature is minimum, the suction of light
Yield has reached minimum, and the luminous intensity that electrocardio receiver detects is maximum.Therefore, the luminous intensity that photelectric receiver receives is also
As fluctuation-type variation is presented in pulse.Pressure pulse speed when touching skin can be slowed down, but be enough to make subcutaneous
The artery and arteriolar dilatation of tissue.The heart rate and pulse data of user are converted to by algorithm, then the heart rate got
ECG Data Transmission Based helps user to calculate the caloric heat of consumption, and calculate movement according to data to Central Control Module
Physiological change in intensity and motion process.
For user when wearing Intelligent bracelet moves, Intelligent bracelet inevitably touches a large amount of sweat and moisture, in order to protect
Electronic component work is unaffected in card Intelligent bracelet, and present invention eliminates USB wired charging interfaces, using wireless charging
Pattern enhances the peripheral hardware leakproofness of bracelet, improves the working life of electronic component.
Wireless charging system such as Fig. 6 mainly uses electromagnetic induction principle, and carrying out energy coupling by coil realizes energy
It transmits.System can be directly system power supply with direct current when working, and can be transformed by rectification circuit if it is alternating current
Direct current is powered, and when receiving coil close to transmitting coil, sense psophometric voltage is will produce in receiving coil, when receiving coil returns
When the resonant frequency on road is identical as tranmitting frequency, it will generate resonance, voltage at this time will reach maximum value, when voltage maximum
The efficiency of transmission of energy has also reached peak efficiency.As long as Intelligent bracelet is placed into wireless charging stake by user, just can realize
Wireless charging not only eliminates the worry of wired charging, also enhances the leakproofness of equipment, improves the component service life.
Built-in self-supporting charging module such as Fig. 7 mainly uses electromagnetic induction principle, can be produced around pillar-shaped permanent magnet
The non-uniform magnetic induction line of magnetisation flux density, pillar-shaped permanent magnet are equivalent to and close in the case where user swings and the movement of springback acts on
Close the movement that loop coil makees cutting magnetic induction line.By Faraday's electromagnetic induction law it is found that magnetic flux is sent out in the circuit of closure
Changing will generate electric current, and this phenomenon that now utilizing field generating current is exactly electromagnetic induction phenomenon, and this electric current is exactly
Induced current, the size of induced electromotive force, directly proportional with the change rate of the magnetic flux by the circuit in circuit.Because user puts
It starts to be different frequency discord different rates when ring, so the induced current that closed annular coil cutting magnetic induction line generates is not
Stable alternating current, unstable alternating current cannot directly be that power storage module is energized, and need to design a rectifying and voltage-stabilizing electricity
Road handles induced current.
The effect of rectification circuit is that alternating current is transformed into direct current, mainly by transformer, whole on the left of rectification circuit such as Fig. 8
Flow diode, capacitive filter, main circuit composition.This example is using bridge rectifier, when alternating current is positive half cycle,
It is just lower negative on transformer Tr output ends, forward voltage is added to D1 and D3, diode D1 and D3 is connected in forward bias at this time,
Backward voltage is added to D2 and D4, diode D2 and D4 end in reverse bias at this time, and electric current filters out positive and negative by D1 and D3
Direct current forms just lower negative half wave rectified voltage on R3；When alternating current is negative half period, forward voltage added to D2 and D4 and
Conducting, adds backward voltage to D1 and D3 and ends, and to filter out positive and negative direct current, it is whole that just lower negative other half-wave is formed on R3
Galvanic electricity pressure.The alternating current handled by rectification circuit is converted into unidirectional pulsating dc voltage, but the latter contains larger exchange
Ingredient reduces the alternating component in DC voltage, retains it so the output end in rectification circuit accesses capacitor filter C
Flip-flop makes the reduction of output voltage ripple coefficient, waveform become more smooth.The voltage exported by rectifying and wave-filtering is unstable
Fixed, so also needing to the processing by regulator circuit, constant output voltage can be just accessed, stable DC is provided
Source.
V3 is input voltage in regulator circuit figure such as 8 right sides, and V4 is output voltage, and Dz is zener diode, and R is limited galvanic electricity
Resistance, A are to compare amplifying circuit, and T is that adjustment is managed, and voltage on the basis of VERF, it is made of zener diode and current-limiting resistance, R1 and
R2 is that voltage change samples comparison module.When V3 changes, Dz and current-limiting resistance R play the role of adjustment circuit, make
Dz voltages VZ with stability is remained unchanged so that output voltage V4 holding stablize it is constant.Output voltage V4=V3-
The difference of Vce, voltage are compared with sampling module, go to adjust the big of VB and Ib after then amplifying by comparing amplifying circuit
It is small, to change the size of Vce.When V4 increases, VF also increases therewith, and VF and reference voltage V ERF are compared, the two electricity
The difference of pressure makes the VB and Ib of adjustment pipe T reduce after comparing amplifying circuit amplification, to make the Vce of adjustment pipe T increase,
Because Vce increases so V4 reduces so that the size that V4 remains stable keeps substantially constant.After regulator rectifier circuit is handled
Just can be that power storage module charges by constant current constant voltage charging mode to constant DC voltage, to ensure safe charging,
Improve the power storage module service life.When bracelet electricity is relatively low, cell voltage is relatively low, thus first pass through constant current mode to power storage module into
Row charging, to ensure charge efficiency and cell voltage is made to increase sharply.When cell voltage reaches standard charge voltage, charge mould
Formula switches to constant-voltage charge pattern, and with the increase of battery capacity, the internal resistance of cell gradually increases, and charging current is gradually reduced, when
When power storage module tends to saturation state, charging current prevents close to zero and overcharges electrical phenomena, influences and reduces the battery longevity
Life.
