Description of drawings
Fig. 1 is an electrical block diagram of the present utility model and as Figure of abstract.
Embodiment
A kind of as shown in Figure 1 instant alarming device, comprise the warning circuit that is arranged in the casing, warning circuit comprises integrated circuit (IC), amplifying triode V, capacitor C, resistance R 1-R6, unidirectional thyristor VT1, VT2, VT3, LED 1, LED2, LED3, loudspeaker BL, power switch S, gauge tap S1, S2, S3, power supply E, unidirectional thyristor VT1 wherein, VT2, anodal and the current-limiting resistance R1 of VT3, R3, the connection of R5 one end connects positive source through power switch S, unidirectional thyristor VT1, VT2, the VT3 control utmost point is respectively through gauge tap S1, S2, S3 and current-limiting resistance R1, R2, the other end of R3 connects, unidirectional thyristor VT1, VT2, the VT3 negative pole respectively with current-limiting resistance R2, R4, R6 one end, filter capacitor C positive pole, the integrated circuit (IC) vdd terminal, loudspeaker BL one end connects, current-limiting resistance R2, R4, the other end of R6 is through LED 1, LED2, LED3 connects power supply E negative pole, filter capacitor C negative pole connects power supply E negative pole, integrated circuit (IC) OSC1, OSC2 end oscillation resistance R7 in parallel, integrated circuit (IC) VSS termination power E negative pole, the base stage of integrated circuit (IC) O/P termination amplifying triode V, the collector of amplifying triode V connects the other end of loudspeaker BL, and the emitter of amplifying triode V connects power supply E negative pole.
1, when gauge tap S1～S3 does not press, unidirectional thyristor VT1～VT3 does not work so integrated circuit (IC) has power supply because of the nothing electric current that sets out is in cut-off state.If during a certain switch closure (as S1), unidirectional thyristor VT1 obtain to set out electric current and conducting this moment, power supply E to integrated circuit (IC), makes integrated circuit (IC) obtain power work by unidirectional thyristor VT1.The alert audio signal that integrated circuit (IC) produces promotes loudspeaker BL and sounds the alarm after triode V amplifies.Power supply E lights LED 1 by current-limiting resistance R2 simultaneously, indicates the position of being monitored.
If more than 2 roads alarm lamps close simultaneously, circuit can be worked in the same old way, and corresponding light emitting diode all can be lighted.Desire to make circuit to stop to report to the police, have only disconnecting power switch S.
3, this circuit is as burglar alarm usefulness, and the choosing of integrated circuit (IC) must be caused trouble SEL1, SEL2 all place vacant state, and this is that the sound that sends is the police car sound equipment.
4, gauge tap S1～S3 also can adopt magnetic control, mode such as light-operated to realize control.
