Embodiment:
More particularly, in the utility model, mainly be made of for the power supply of door magnetic chip the first triode Q1, the second triode Q2, the 3rd triode Q3, the first diode D1, first inductance L 1, the 6th capacitor C 6 etc., the high-frequency signal radiating circuit mainly is made up of the 4th triode Q4, the 5th triode Q5, second inductance L 2, the first crystal oscillator X1 etc.
Tongue tube is opened a way when magnet leaves tongue tube S1,2 chargings make the first triode Q1, the second triode Q2 conducting through the 3rd resistance R 3 to power supply+EC to second capacitor C by first resistance R 1, and the voltage of battery BT1 is added in the 18 resistance R 18 and the 8th capacitor C 8 of the first chip U1 after 3 filtering of the 3rd capacitor C forms filtering circuits, prevents that the power supply high frequency from producing interference to chip U2; The operational voltage value that stabilivolt Z1 voltage stabilizing to the second chip U2 requires, and by the 19 resistance R 19 connection power end+ECC, can burn out chip if directly voltage is added to the first chip U1 pin. the EXT end output high-frequency impulse of the first chip U1 is controlled the 3rd triode Q3 work, boost by first inductance L 1 and to press through D1 half-wave rectification C6 filtering becoming galvanic current, through the 6th resistance R 6,7 fens pressure-controlled first chip U1 output duty cycles of the 7th resistance R are regulated automatically and are made voltage be stabilized in certain value, the 4th capacitor C 4 is a negative feedback electric capacity, playing the effect of fast and stable voltage. stable voltage is added in the 4th triode Q4 of the second chip U2 and high-frequency signal radiating circuit, the 5th triode Q5 provides operating voltage that the information that door magnetic leaves is launched, the base stage of the 4th triode Q4 is connected with second inductance and RF transmitter by the 9th resistance R 9. and wherein the 8th resistance R 8 and the 5th capacitor C 5 are formed filtering circuit, prevent high-frequency self-excitation, R8 also has the effect of circuit current limliting to HFS simultaneously; The 7th capacitor C 7 leaches for the crystal oscillator harmonic wave, second inductance L 2 has been high-frequency isolation effects, prevent that high frequency from being filtered by the 5th capacitor C 5. this end-of-job when 1 charging of first capacitor C finishes, the first triode Q1, the second triode Q2 quit work. and first resistance R 1, second resistance R, 2 capacitor C 2 are formed the charging delay circuit, the adjustable size of adjusting R1, R2, capacitor C 2 values saves the run duration of the first triode Q1, the second triode Q2, and the run duration of this example first triode Q1, the second triode Q2 was controlled at 2 seconds.
Burned in advance self-compiling program in single-chip microcomputer U2, when 1 pin of single-chip microcomputer U2 has the voltage input, just whether the 3 pin voltages of program detection single-chip microcomputer U2, if when detecting when low 2 pin output induction door magnetic magnet by single-chip microcomputer U2 and leaving tongue tube S1, signal controlling the 4th triode Q4, the 5th triode Q5 go out this signal by high-frequency emission, 7 pin of single-chip microcomputer U2 output simultaneously one " tick---" sound is amplified by the 9th triode Q9 and sends the sound by hummer K1 again.
When if 3 pin of program detection single-chip microcomputer U2 are high level behind the chip power, when the 2 pin output magnet of single-chip microcomputer U2 leaves tongue tube S1, signal controlling the 4th triode Q4, the 5th triode Q5 go out this information by high-frequency emission, continuous " tick---tick " sound of 7 pin of single-chip microcomputer U2 output is simultaneously amplified by the 9th triode Q9 and sends the sound by hummer K1 again.
Base stage series and parallel the 11 resistance R 11 of the 6th triode Q6 and the 12 resistance R 12, the 11 resistance R 11 are connected the 12 resistance R 12 ground connection in the low-voltage testing circuit with 3V power supply BT1.The collector of the 6th triode Q6 the 14 resistance R 14 of connecting is connected with the base stage of the 7th triode Q7, and the base stage of the 6th triode Q6 is connected with the 3V power supply by the 11 resistance R 11; The collector of the 7th triode Q7 the 16 resistance R 16 back of connecting is connected with the base stage of the 8th triode Q8, draws between the base stage of the 16 resistance R 16 and the 8th triode Q8 to connect that the 15 resistance R 15 is back to be connected with the 3V power supply.Draw between the collector of the 8th triode Q8 and the 17 resistance R 17 and the 18 resistance R 18 to be communicated with and be high/low pressure check point with 3 pin of single-chip microcomputer U2.
Low pressure testing principle: when cell voltage is lower than 2.0V, the 6th triode Q6 did not work when divider resistance the 12 resistance R 12 both end voltage were lower than 0.7V, the 7th triode Q7, the 8th triode Q8 work, when door magnetic triggers, when the 3 pin low pressure test sides of single-chip microcomputer U2 are noble potential, single-chip microcomputer U2 thinks battery low pressure, and continuous " tick---tick " the voice suggestion sound of the 7 pin output of chip comes the reminding user to replace battery with this.As the 12 resistance R 12 both end voltage greater than 0.7V, the 6th triode Q6 conducting, the 7th triode Q7, the 8th triode Q8 close, the 17 resistance R the 17, the 18 resistance R 18 dividing potential drop place voltages are low-voltage, at this moment 3 pin of single-chip microcomputer U2 detect and are electronegative potential, at this moment single-chip microcomputer thinks cell voltage greater than 2V, and 7 pin of single-chip microcomputer U2 output one " tick---" prompting user door magnetic is working properly at present.
The utility model provides a kind of thinking and method of auditory tone cues wireless door magnetic inductor; the method and the approach of this technical scheme of specific implementation are a lot; the above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.The all available prior art of each component part not clear and definite in the present embodiment is realized.
