Operation principle:
Other electrical equipment in electrical network are equivalent at power firestreak AC220V(L), zero line AC220V(N) a two ends resistance R1 in parallel.
One. switch K Guan Bi
1., when civil power 220V has electricity, switch K Guan Bi, now the state of lamp is sensing lamp.
Rectifier bridge output A point voltage is through the base stage of stabilivolt D1, resistance R4 to audion Q4, audion Q4 conducting, audion Q5 cut-off, the positive pole of accumulator E provides upper offset voltage by resistance R6 to audion Q6, audion Q6 turns on, audion Q7, Q8 end, by inductance coil L1, electric capacity C5, resistance R7, audion Q7, the booster circuit of audion Q8 composition does not works；
The rectifier bridge output A point voltage base stage by Zener diode D1, resistance R9 to audion Q2, audion Q2 turns on, and audion Q3 ends, and buzzer F does not works, silent；
Rectifier bridge output A point voltage provides a forward voltage by Zener diode D1, resistance R10 to 3 feet of LED drive chip U2, if now there being people, human body induction module U1 output low level, audion Q1 ends, 3 feet of LED drive chip U2 are still high level, LED drive chip U2 work, the 5 of LED drive chip U2,6 feet have high-frequency oscillation signal to export, the LED of unilateal conduction is bright；Now the 5 of LED drive chip U2,6 loop currents flowed to the positive pole of accumulator by 2 feet of U2, the negative pole of accumulator return to ground, also charge a battery while such lamp is bright；And when nobody, human body induction module U1 exports high level, making audion Q1 turn on by resistance R12,3 feet of LED drive chip U2 are pulled to low level, the not starting of oscillation of LED drive chip U2, now the 5 of U2,6 feet be high-impedance state, LED does not works.
2., during civil power 220V power-off, switch K Guan Bi, the state of lamp is emergent long on state of, and now warning is only worked by sensing body block U1, and someone reports to the police, and nobody does not reports.
Rectifier bridge output A point no-voltage, 3 foot no-voltages of LED drive chip U2, LED drive chip U2 does not works.The positive pole of accumulator E passes through resistance R8, switch on wall K, load resistance R1 in outer net, base stage (the base stage no-voltage due to audion Q4 of resistance R5 to audion Q5, audion Q4 ends), audion Q5 turns on, audion Q6 ends, by inductance coil L1, electric capacity C5, resistance R7, audion Q7, the booster circuit work of audion Q8 composition, oscillator signal is by arriving the positive pole of LED after diode D4 rectification, due to resistance R3, diode D3 provides a below-center offset electric current to the base stage of PNP triode Q9, PNP triode Q9 is made to turn on, the cathodal current of LED returns to ground through Q9, LED is bright.If now having people in the search coverage of human body induction module U1, the 2 foot output low levels of human body induction module U1, audion Q1, Q2 end, the positive pole of accumulator E provides electric current by resistance R2 to the base stage of audion Q3, audion Q3 turns on, and buzzer F works, and sends chimes of doom.If now unmanned in the search coverage of human body induction module U1, the 2 foot output high level of human body induction module U1, audion Q2 turns on, and audion Q3 ends, and buzzer F does not works.
Two. when switch K disconnects
When switching K and disconnecting, no matter civil power 220V with or without, LED does not all work.But reporting to the police and work, someone reports to the police, and nobody does not reports
Owing to rectifier bridge exports A point no-voltage, audion Q4 ends, owing to resistance R5 no current flows through, audion Q5 ends, the resistance R6 connected with the positive pole of accumulator E provides upper offset to audion Q6, audion Q6 turns on, and the booster circuit being made up of inductance coil L1, electric capacity C5, resistance R7, audion Q7, Q8 does not works, and LED does not works.
Sensing part work is as follows: if having people in the search coverage of human body induction module U1, the 2 foot output low levels of U1, and audion Q1, Q2 end, the positive pole of accumulator E provides electric current by R2 to the base stage of audion Q3, Q3 turns on, and buzzer F works, and sends chimes of doom.If now unmanned in the search coverage of human body induction module U1, the 2 foot output high level of U1, audion Q2 turns on, and audion Q3 ends, and buzzer F does not works.
