Abstract
The utility model discloses a gate security protection warning circuit, including trigger circuit, switch circuit and auto -lock warning circuit, trigger circuit includes switch S1, resistance R3, electric capacity C2 and electrode slice A, and switch circuit includes triode V2 and triode V3, and auto -lock warning circuit includes triode V4 and relay K. The utility model discloses gate security protection warning circuit combines together through gate switch and electrode slice, realizes dual protection controller's function to the circuit utilizes the characteristic of relay, makes the alarm in case triggered will continued work, the no longer influence in the source of being triggered, thus prevent that the burglar from destroying the source of triggering and causing the alarm to become invalid, have consequently that the function is various, alarm effect good, trigger sensitive advantage.
Description
Technical field
The utility model is related to a kind of warning circuit, specifically a kind of gate security alarm circuit.
Background technology
With the continuous improvement of living standard, security protection work of the people to family is day by day paid attention to, especially night master
When people sleep soundly, thief slips in family and steals valuables, therefore, it is very effective anti-that burglar alarm is installed at home
Robber's mode.But the alarm for being used for average family on market is simultaneously few, using infrared ray, gate more than several alarms of minority
The devices such as switch the defect such as there is also reflection insensitive, rate of false alarm be high as trigger source, and for veteran burglar,
It is easy to crack this kind of alarm, so as to take the measure of cracking, continues to commit a crime.
Utility model content
The purpose of this utility model is to provide a kind of simple structure, gate security alarm circuit easy to use, to solve
The problem proposed in certainly above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme：
One kind gate security alarm circuit, including triggers circuit, on-off circuit and self-locking alarm circuit；The triggers circuit
Including switch S1, resistance R3, electric capacity C2 and electrode slice A, on-off circuit includes triode V2 and triode V3, self-locking alarm circuit
Including triode V4 and relay K；
Emitter stage, loudspeaker B, the contact K-1 of power supply VCC and relay K of one end connecting triode V3 of the switch S1,
The other end of switch S1 connects the other end of the contact K-1 of resistance R3, electric capacity C2, the base stage of triode V2 and relay K, resistance
The other end connection electrode piece A of the other end connection electric capacity C1, the emitter stage of triode V2 and relay K, electric capacity C2 of R3, three poles
The base stage of the colelctor electrode connecting triode V3 of pipe V2, the colelctor electrode connection electric capacity C1 and resistance R4 of triode V3, resistance R4's is another
The base stage of one end connecting triode V3, the colelctor electrode of triode V4 connects the other end of loudspeaker B, the emitter stage connection of triode V4
The other end of relay K.
As preferred version of the present utility model：The switch S1 is gate controlled switch.
As preferred version of the present utility model：The relay K is normally opened contact relay.
Compared with prior art, the beneficial effects of the utility model are：The utility model gate security alarm circuit passes through
Gate controlled switch and electrode slice combine, and realize the function of dual security protection control, and circuit is using the characteristic of relay so that report
Alert device be once triggered will continuous firing, no longer affected by trigger source, so as to prevent burglar's destruction trigger source from causing to report to the police
Device fails, thus with vdiverse in function, warning effect it is good, trigger sensitive advantage.
Description of the drawings
Fig. 1 is the circuit diagram for gating security alarm circuit.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Refer to Fig. 1, one kind gate security alarm circuit, including triggers circuit, on-off circuit and self-locking alarm circuit；Institute
Stating triggers circuit includes switch S1, resistance R3, electric capacity C2 and electrode slice A, and on-off circuit includes triode V2 and triode V3, from
Lock warning circuit includes triode V4 and relay K；
Emitter stage, loudspeaker B, the contact K-1 of power supply VCC and relay K of one end connecting triode V3 of the switch S1,
The other end of switch S1 connects the other end of the contact K-1 of resistance R3, electric capacity C2, the base stage of triode V2 and relay K, resistance
The other end connection electrode piece A of the other end connection electric capacity C1, the emitter stage of triode V2 and relay K, electric capacity C2 of R3, three poles
The base stage of the colelctor electrode connecting triode V3 of pipe V2, the colelctor electrode connection electric capacity C1 and resistance R4 of triode V3, resistance R4's is another
The base stage of one end connecting triode V3, the colelctor electrode of triode V4 connects the other end of loudspeaker B, the emitter stage connection of triode V4
The other end of relay K.
Switch S1 is gate controlled switch.Relay K is normally opened contact relay.
Operation principle of the present utility model is：Switch S1 is gate controlled switch, and, when door is closed, inside disconnects for it, and door is opened
When, inside conducting, electrode slice A is arranged on the inner side of door handle, and when using, switch on power VCC, under normal circumstances in S1 constantly
Open, and electrode slice A false touches are signaled, triode V2 cut-offs, therefore V3 and V4 are turned off, relay K is failure to actuate, and loudspeaker B does not send out
Raw, when someone opens door, staff Touching electrode A, human induction current is added in the base stage of triode V2 after electric capacity C2,
So that the colelctor electrode of triode V2 has electric current to export, it is added on triode V3 and turns it on, the electric current for flowing through triode V3 is passed through
Resistance R4 is added on triode V4, and V3 conductings, loudspeaker B sends chimes of doom, while relay K is powered, the K-1 adhesives of its contact, electricity
Road enters self-locking state, even if therefore staff leaves electrode slice, circuit still normally, chimes of doom will not interrupt, if steal
Thief discovers in advance the presence of electrode slice, wearing gloves or destruction electrode slice, then when burglar opens the door and come in, in gate controlled switch S1
Portion turns on, again such that triode V2 is connected, later step is identical with above-mentioned, reaches the function that self-locking is persistently reported to the police.
