The light-operated circuit principle: this circuit is made up of potentiometer W1, photo resistance RG, NAND gate YF1, the resistance of photo resistance on daytime RG diminishes, voltage ratio is less than the threshold level of YF door, therefore block the YF1-2 pin, no matter have voiceless sound YF1-3 pin to be always ' 1 ' state, swing to through three NAND gate YF2, YF3, YF4, making the YF4-11 pin is ' 0 ' state, not conducting of controllable silicon guarantees that daytime, lamp did not work.It is big that the resistance of photo resistance at night RG becomes, and voltage ratio is ' 1 ' state greater than the threshold level of YF door, is open-minded to the YF1-2 pin, and state output terminal is just determined by the YF1-2 state.If this moment, nobody passed through, there is not sound, YF1-3 is constant, and lamp does not work.If someone is by sounding, YF1-2 moment is ' 1 ' state, causes YF1-3 moment to export ' 0 ' state, swings to through three NAND gate YF2, YF3, YF4, and making the YF4-11 pin is ' 1 ' state, through R ₆Trigger the controllable silicon conducting, make lamp bright.

The sound control circuit principle: this circuit is by resistance R ₂, R ₃, R ₄, capacitor C ₂, microphone M, triode BG ₁Form triode BG ₁It is a sound amplifying circuit.Operation principle is as follows: when unmanned by the time voiceless sound send BG ₁Conducting makes very ' 0 ' state of BG1-C, and causing YF1-3 is ' 1 ' state, swings to through three not gate YF2, YF3, YF4, and causing YF4-11 is ' 0 ' state, thus be day and night lamp can be not bright.When sounding by the people daytime, BG ₁Moment ends, and makes BG1-C utmost point moment be ' 1 ' state, but this moment, YF1-1 was a blocked styate, and lamp does not still work.Sound by man-hour when night, state is the same, because this moment, YF1-1 opened ' 1 ' state, YF1-2 moment ' 1 ' state, causing the YF1-3 pin is ' 0 ' state, through swinging to of three NAND gate YF2, YF3, YF4, causing the YF4-11 pin is ' 1 ' state, through current-limiting resistance R6, trigger the controllable silicon conducting, so lamp is lighted.

The emergency circuit principle: this circuit is by resistance R 25, R26, R27, BG4, BG5 forms, the signal of emergent control is taken from line voltage, because when entering emergency rating, the 220V alternating current of electrical network sends the instruction that has a power failure by fire protection control center control, because the present invention has the ability of the every function of automatic recovery, can change repeatedly from " normally " to " meeting an urgent need ", to equipment all without any influence, so the present invention is to have or not line voltage as the signal that whether enters emergency rating, in case temporary interruption rather than emergency rating occur, just all emergency functions have been carried out once checking, automatically the attitude that restores to the original state all behind the incoming call there is no any harmful effect.Wherein: the direct voltage that R25 is the line voltage sample resistance, obtain D5 is delivered to the base stage of BG4, when just often, and U _D5Cause the BG4 conducting, cause BG5 to end through R25, the collector electrode of BG5 is an one state, delivers to the transmission that the YF4-13 pin does not influence the sound control circuit level, is in normal condition; When emergency event took place, line voltage removed, and caused U _D5=0, causes that BG4 ends, the BG5 conducting, " 0 " state that causes the collector electrode of BG5 to present, cause the reset of YF4-13 pin, block the YF4-12 pin, and lead the YF4-11 pin and present one state, affact YF4-8 and 9 pin through C4, cause YF4-10 pin moment reset state, the Q that triggers RS1 through C4, R14 differential holds the set state, causes the BG2 conducting to become resistance; The one state of while YF4-11 pin, cause the DK2 conducting, making that L is luminous provides " meeting an urgent need " illumination, this moment, the collector electrode because of BG5 presented " 0 " state, cause the reset of YF4-13 pin, block the YF4-12 pin, so YF4-11 pin state is not subjected to the control of acousto-optic control signal, it is constant to remain on one state, and just " meeting an urgent need " illumination is not subjected to time-delay control and kept burning day and night.When emergent accident is removed, the power system restoration power supply, as previously mentioned: BG4 conducting, BG5 end, the set of YF4-13 pin, through a delay cycle, the reset of YF4-11 pin causes DK2 to end, and causes among the L no current by not luminous, returns to normal condition and stop this emergency lighting.

The whole circuit course of work: this circuit powers up for the first time and should be in " charging " operating state, and voltage comparator ic 2 is according to the reference voltage U of 3 pin at this moment _IN+, compare the output control level with electrical network sampling voltage in the variation of IC2-2 pin, have only corresponding U _IN-≤ U _IN+Line voltage, could be by DK1 to battery charging, and be higher than selected voltage, turn-offed its copped wave by controllable silicon, therefore twice of every half cycle DK1 conducting, its frequency are per second 200 times, help charging; Because of the electric current LD1 that flows through makes it luminous, indicating circuit is in " charging " operating state in charging.Daytime: because of photo resistance diminishes, cause YF1-pin level to be lower than the threshold level of YF1, the level that blocks other pin passes through, and output presents ' 1 ' state, and the YF4-11 pin is ' 0 ' state, so lamp does not work.Night: because of photo resistance becomes big, cause YF1-1 pin level to be higher than the threshold level of YF1, the level of opening other pin passes through, and the state of YF4-11 pin is by the state decision of YF1-2 pin.When night, nobody passed through, YF1-2 still was ' 0 ' state, and the YF4-11 pin is ' 0 ' state still, so lamp does not work.This moment, circuit state was as follows: the reset of RS1-Q end causes that BG2 ends, the reset of RS2-Q end causes that BG3 ends, U _D5Cause BG4 conducting, BG5 to present one state through R25, cause the set of YF4-13 pin not influence the transmission of acousto-optic control signal by its collector electrode.

The course of work from " charging " state exchange to " illumination " state is: when having night the people to pass through, sound through BG ₁Amplify, when the negative half period of audio frequency, the YF1-2 pin presents ' 1 ' state, and the reset of YF1-3 pin causes the set of RS2-Q end, causes the BG3 conducting, causes DK1 to end, and at first finishes the program that stops " charging "; The reset of YF1-3 pin also causes the set of YF2-4 pin, charges to C3 through D6, works as U _C3When being higher than threshold level, cause the reset of YF3-10 pin, when the YF3-10 pin jumped to " 0 " under " 1 ", it was jumped down along triggering the set of RS1-Q end, causing the BG2 conducting through C6, R14 differential, and 16 of low-resistance is parallel on the R17, finished the change resistance before luminous; The reset of YF3-10 pin causes the set of YF4-11 pin, cause the DK2 conducting to make that L is luminous to provide illumination.

The course of work from " illumination " state exchange to " charging " state is: after audio signal, the YF1-2 pin causes the YF1-3 set for " 0 ", does not influence the state of RS2, causes the YE2-4 reset simultaneously, causes D6 to end isolation, causes U _C3Through the R5 discharge, work as U _C3When being lower than threshold level, cause the set of YF3-10 pin, cause the reset of YF4-11 pin, trigger the RS1-Q reset, cause BG2 to end through C7, R12 differential, make R16 withdraw from load, the electric current of the L that reduces to flow through is finished earlier and is become resistance work; The reset of YF4-11 pin causes DK2 to turn-off " illumination "; The YF4-11 pin jumps to " 0 " under " 1 " simultaneously, trigger the RS2-Q reset, cause BG3 to end, cause DK1 to turn on and off finishing pressure limiting copped wave through C8, R9 differential according to the output of IC2, return to " charging " state, the luminous indicating circuit of LD1 is operated in " charging " state.

The course of work that changes " meeting an urgent need " state from " normally " over to is: when the accident generation, fire protection control center sends accident and instructs when making grid power blackout, causes U _D5Be 0, cause that BG4 ends, the BG5 conducting, the current collection of BG5 is " 0 " state very, cause the reset of YF4-13 pin, cause YF4-11 pin set state, cause the DK2 conducting, make that L is luminous to provide illumination, blockade because of YF4-13 pin level "0", so the time-delay control level can not change the state of YF4-11 pin, so emergency lighting is kept burning day and night.

The course of work that changes " normal illumination " state from " meeting an urgent need " state over to is: when accident is removed, and power system restoration power supply, U _D5Cause BG4 conducting, BG5 to end, cause the set of YF4-13 pin, open the YF4-12 pin,, cause DK2 to turn-off, return to normal holding state through a delay cycle.
