Q3, resistance R1, resistance R2, resistance R3, capacitor C1, buzzer Y1, alarm lamp LED；
The positive terminal A1 is connected to the anode of feeder ear DC, and negative pole end B1 is connected to the cathode of feeder ear DC, feeder ear
The anode of DC is connected to capacitor C1 by diode D1, and the base stage of triode Q1 is connected to positive terminal A1, three poles by resistance R1
Pipe Q2 is connected in the connecting node of diode D1 and capacitor C1 by resistance R2, and the base stage of triode Q3 is connected by resistance R3
To the emitter of triode Q2, the collector of triode Q2 is connected to the connecting node of the anode of positive terminal A1 and feeder ear DC
On, the emitter of triode Q1 and triode Q3 are all connected to the cathode of feeder ear DC, the collector of diode D1, triode Q2
Be connected to the connecting node of the anode of positive terminal A1 and feeder ear DC, and between be provided with diode D2, the current collection of triode Q3
Alarm lamp LED, buzzer Y1 and alarm are connected in the connecting node of pole connection buzzer Y1, triode Q3 and buzzer Y1
Lamp LED is both connected in the connecting node of anode of positive terminal A1 and feeder ear DC.
The utility model has the following beneficial effects: the loss of electric current can be controlled and be lost without reason, inside battery meeting ensure that
Persistently there is electricity, electric quantity loss can be reduced, plays the effect of saving, environmental protection, power saving.
Detailed description of the invention:
Fig. 1 is the circuit diagram of the utility model.
Specific embodiment:
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines and is specifically illustrating, and the utility model is further described.
As shown in Figure 1, installing power alarm reminiscences additional by formula metal detection door, it is characterised in that: power including 220V
The positive terminal A1 and negative pole end B1 at end, detection door inside 12V feeder ear DC, diode D1, diode D2, triode Q1, three poles
Pipe Q2, triode Q3, resistance R1, resistance R2, resistance R3, capacitor C1, buzzer Y1, alarm lamp LED；
The positive terminal A1 is connected to the anode of feeder ear DC, and negative pole end B1 is connected to the cathode of feeder ear DC, feeder ear
The anode of DC is connected to capacitor C1 by diode D1, and the base stage of triode Q1 is connected to positive terminal A1, three poles by resistance R1
The base stage of pipe Q2 is connected in the connecting node of diode D1 and capacitor C1 by resistance R2, and the base stage of triode Q3 passes through resistance
R3 is connected to the emitter of triode Q2, and the collector of triode Q2 is connected to company of the positive terminal A1 even with the anode of feeder ear DC
It connects on node, the emitter of triode Q1 and triode Q3 is all connected to the cathode of feeder ear DC, diode D1, triode Q2
Collector is connected to positive terminal A1 and is even provided with diode D2, triode Q3 between the connecting node of the anode of feeder ear DC
Collector connection buzzer Y1, triode Q3 and buzzer Y1 connecting node on be connected with alarm lamp LED, buzzer Y1 and
Alarm lamp LED is both connected to positive terminal A1 even and in the connecting node of the anode of feeder ear DC, and buzzer Y1 and alarm lamp LED are simultaneously
Connection connection；
Feeder ear DC gives capacitor C1 quick charge, while triode Q1 is connected, while 12V voltage is connected through diode D2
It charges to DC, after triode Q1 conducting, triode Q2 cut-off ends triode Q3, buzzer Y1 and LED alarm lamp not work
Make, when certain reasons make to power off suddenly by formula metal detection door, after internal electric source is without 12V voltage output, makes through formula metal
