The present invention adopts two joint AAA alkaline dry batteries to power to circuit board, and supply voltage is+3V.
Be described in detail below by way of each functional module of accompanying drawing to control circuit board of the present invention:
Electric power management circuit
The input of electric power management circuit is connected with battery, and other circuit module on the backward control circuit board of voltage stabilizing process is powered.As Fig. 3, electric power management circuit with LDO chip U2 for core is formed.Battery is after power supply after a while, and output voltage can progressively decline, constant in order to ensure the supply voltage in microcontroller power pins, needs to realize voltage stabilizing process by power circuit.The concrete annexation of electric power management circuit of the present invention is as follows:
Electric power management circuit comprises chip U2, electric capacity C3, switch S 1, resistance R18, microcontroller U1, resistance R16 and resistance R17.1 foot of described chip U2 connects the positive pole of battery, 2 feet of chip U2 connect the negative pole of battery, 1 foot of the one chip termination U2 of electric capacity C3,2 feet of another chip termination U2 of electric capacity C3, the positive pole of one termination battery of switch S 1, one end of the other end connecting resistance R18 of switch S 1,3 feet of another chip termination U2 of resistance R18,3 feet of chip U2 connect 7 feet of microcontroller U1; Resistance R16 and R17 connects, 4 feet of the public chip termination U2 of resistance R16 and R17,5 feet of another chip termination U2 of resistance R16, the other end ground connection of resistance R16.
Voltage VCC after the 5 feet output voltage stabilizing process of U2, VCC powers directly to microcontroller.The voltage VCC that 5 feet export is controlled by resistance R16 and R17.Pass between voltage VCC and resistance R16 and R17 is VCC=(R1+R2)/R21.204.3 feet of U2 are Enable Pin, apply high level to 3 feet, and U2 works; Apply low level to 3 feet, U2 forbids.Button S1 works for starting LDO chip U2.LDO chip U2 has 30mV ultra low differential pressure, this characteristic can extend the service life of battery, because along with the access times of product increase, cell voltage will inevitably decline, and the ultra low differential pressure of 30mV, when can ensure that the supply voltage of battery drops to 2.43V in theory, product still can work, and therefore extends the service life of battery; LDO chip U2 has 400us and exports response time fast in addition, and this characteristic can guarantee that control circuit board reliably powers on.When pressing the button on product casing first, because the quick output response time of power supply chip, power supply chip can export+2.4V voltage immediately, microcontroller can power at once and enter normal mode of operation, and export high level at the 7th pin (circuit network symbol is POW-ON) of microcontroller, after button unclamps, because the 7th pin of microcontroller exports high level, so the voltage output enable of power supply chip U2 still remains high level, continue to export+2.4V voltage, holding circuit normally works.

Booster circuit completes boost function under the control of the micro-controller.The pwm signal of microcontroller output duty cycle change, the dutycycle of pwm signal is little, then VDD value is lower; The dutycycle of pwm signal is large, then VDD value is higher.When pwm signal is high level, audion T1 conducting, battery, inductance L 1 and audion T1, form current path, this process is charged to inductance L 1.When pwm signal is low level, audion T1 ends, and inductance L 1 is charged to capacitance group C1, C2 by diode D1.Due to the unilateral conduction of diode D1, capacitance group C1, C2 can not be anti-phase to battery charging, or discharge over the ground.Resistance R20 plays damping action to pwm signal, suppresses frequency glitches noise, improves Electric Circuit Electromagnetic Compatibility performance.Electric capacity C4 provides signal communication path.
