Abstract

The utility model relates to an alarm controller which belongs to the technical field of alarms, and solves the problem that at present an ordinary lock has an anti-theft function without alarm. The utility model is composed of an electronic module 1, a switch 2, a piezoelectric sheet 3 and a battery 4, wherein, the electronic module 1 is composed of integrated blocks IC1, IC2, transistors BG 1, BG 2, D1, D2, a resistor, a capacitor and a vibrating detector Q; the switch 2 is connected or linked with the latching mechanism of the lock. The utility model has the advantages of smart structure, simple structure, convenience for the linkage with various locks and adoption locks with switches to form anti-theft alarm products, reliable anti-theft performance and good effect of strong alarm sounds. The utility model can be used for the anti-theft alarm of a motorcycle, a bicycle, a strong box, a cabinet, a desk, a bag, etc.

Description

A kind of alarm control unit

The utility model is a kind of miniature automatic alarm control unit, connects with various common locksets to do the use of automatic alarm lock tool, or adopts the belt switch tapered end to have the burglar alarm product of one's own.

At present, most of locksets are mechanical types, and its anti-theft pick-proof is to improve soundness and mechanism's exquisiteness, but can not prevent the burglar that plays one's cards well, can not burglar alarm, and its reliability is influenced.

The purpose of this utility model is to provide a kind of electronic alarm device to common lockset, makes this series products upgrading and improves anti-theft effect; Simultaneously warning device is carried out auto-control Design, make product have good practical value.

The utility model is design like this: alarm control unit is made up of electronic module 1, switch 2, piezoelectric patches 3, battery 4, it is characterized in that electronic module 1 is by ic chip ₁, IC ₂, transistor BG ₁, BG ₂, D ₁, D ₂, resistance, electric capacity and vibrating detector Q form oscillating mode electronics automatic alarm circuit and be packaged into modular construction; Electronic module 1 is drawn six roots of sensation connection lead and is linked with switch 2, piezoelectric patches 3, battery 4 respectively; The blocking mechanism of switch 2 and lockset is connected or links.

Switch 2 gives electronic module 1 power supply by battery 4 by switch 2, IC in the electronic module 1 when the lockset block action _1b, R ₃, C ₂Form the locking delay circuit, 10 seconds locking preparatory stages were provided.

Vibrating detector Q adopts unidirectional mercury cut-off, and very small vibration is promptly closed, by ic chip _1c, IC _1a, capacitor C ₁The oscillator of forming passes through BG ₁, IC ₂, BG ₂Be connected on the piezoelectric patches 3.

Piezoelectric patches 3 has the parallel connection boosting resonant inductance, and is encapsulated in the electronic module 1.

The utility model has the advantages that: adopt the modular package structure, volume is little, firm, waterproof, anti-pounding.Structure is small and exquisite, and is simple, is convenient to link to each other by switch with the various types lockset very much, constitutes oscillating mode automatic antitheft alarm lock, guarantees the stolen reliably warning exactly during by sled of lockset, has the stronger deterrence sound.

Below in conjunction with accompanying drawing the utility model is elaborated.

More than three accompanying drawings constitute a most preferred embodiment of the present utility model.

It two as principle is: when lockset rotates locking with key, cause projection to break away from and stir pin, by spring force depress switch K closure, beginning A point current potential is a high level, IC _1bOutput low level is passed through D ₃Make IC _1cLocking.No matter vibrating detector Q state how, IC _1dKeep low level, BG ₁, BG ₂All end, so do not produce alarm sound.A point current potential is with C ₂Charging reduces gradually, IC after 10 seconds _1bOutput switching activity is a high level, and the locking preparatory stage finishes.Because D ₃Buffer action, can not make IC _1cUpset.In the phase was waited in warning, as long as vibrating detector Q has very small vibration, mercury contact will be closed, IC _1c, C _1a, C ₁Structure or positive feedback vibration are through IC _1dAnti-phase driving BG ₁Conducting, IC ₂Conducting is through BG ₂Amplifying provides the HTD piezoelectric patches to send alarm sound.During the warning, IC _1aThe output high level is through D ₂Give C ₃Rapid charge, IC subsequently _1aBe output as low level, C ₃Pass through R ₄Discharge is through R ₄C ₃After time, make IC _1cOutput becomes high level, IC _1dOutput low level, BG ₁By stopping warning.Suitably select R ₄C ₃Can control time of fire alarming about 20～25 seconds.Vibrating detector Q is subjected to then continuous alarm of continuous shaking.Piezoelectric patches HTD goes back the parallel connection boosting inductance L except that itself has sound-aid cavity, can regulate oscillation frequency and make L and H TD generation parallel resonance make the HTD two ends obtain maximum voltage, and sound improves greatly, thereby plays the burglar alarm effect effectively.
