Photoelectrical coupler model is 4N25.
Battery pack E is rechargeable battery pack, and capacity is 6V.
Operation principle of the present utility model is: NAND gate F1 and triode VT1 etc. form a simple automatic charger.When battery pack E low voltage, after potentiometer RP1 dividing potential drop, be added in the voltage of NAND gate F1 input lower than its threshold voltage, NAND gate F1 exports high level, and triode VT1 conducting, battery pack E is charged.Otherwise, when E voltage is higher, NAND gate F1 input current potential is higher than its threshold voltage, NAND gate F1 output low level, triode VT1 ends, battery pack E stops charging, and resistance R2 is used for the trickle charge of battery pack E, and it can avoid NAND gate F1 and triode VT1 to fill frequent upset near tortoise voltage and break-make critical.
The composition such as photoelectrical coupler U1, NAND gate F2, NAND gate F3 and triode VT2, relay K memory-type emergency lightening control circuit, when there being civil power, no matter whether bulb M1 lights, NAND gate F2 input is high level, and it exports NAND gate F3 input 1 is low level, and not gate F3 input 2 is high level, NAND gate F4 output is low level, triode VT2 ends, and relay K is in release condition, and bulb M2 does not work.
When lamp M1 being lighted when there is people indoor (switch S closes), lamp M1 both end voltage is through resistance R1 step-down, diode D2 rectification, optocoupler U1 is made to work after electric capacity C1 filtering, NAND gate F3 input 2 is high level, and electric capacity C3 is filled electricity, because NAND gate F3 input 1 is still low level, therefore bulb M2 still can not light, if now have a power failure, then because electric charge on C3 is by resistance R6, bulb M2 discharges slower, NAND gate F2 input 2 is made still to keep high level in a long time, and electric charge discharges very fast on electric capacity C2 by resistance R4, NAND gate F2 input 2 is made to become low level very soon, and output becomes high level, like this, when two inputs of NAND gate F3 are high level simultaneously, its output switching activity is low level, NAND gate F4 exports high level, triode VT1 conducting, relay K adhesive, bulb M2 is lit, simultaneously, voltage on bulb M2 feeds back to NAND gate F3 input 2 by resistance R6, make NAND gate F3, NAND gate F4, the state of relay K remains unchanged, bulb M2 self-locking is luminous, incoming call is recovered again after having a power failure, then bulb M1 lights, NAND gate F3 input 1 becomes low level, bulb M2 automatic distinguishing.
If indoor unmanned when having electricity, bulb M1 is switched off, then photoelectrical coupler U1 ends, and on electric capacity C3, electric charge is released complete by resistance R6 and bulb D2, and NAND gate F3 input 2 becomes low level, if have a power failure during this period, although NAND gate F3 input 1 becomes high level, not gate F3 still can not open, and triode VT1 still ends, relay is failure to actuate, therefore bulb M2 can not be lit.
