The input terminal is provided with a piezoelectric sound conducting piece S, and the output terminal is provided with a controllable silicon SCR. An alarm light S and an alarm bell F in the alarming unit are separated from the casing. The utility model overcomes the defect of poor acoustooptic effect of the existing alarms, and has the advantage of strong versatility. The theftproof strong acoustooptic synchronous alarm is suitable for the theft prevention of exhibition halls, museums, banks, etc.

Description

Anti-theft strong sound and optical synchronous alarm
The utility model relates to burglar alarm, the synchronous alarm of particularly a kind of antitheft strong acoustooptic.
Various theft-proof electron alarms or far infrared alarm are arranged at present, these alarm sound, light effect a little less than, and, because adopting combined installs, both signal received, controlled and carried out each unit of reporting to the police and all was assemblied in one, so be difficult to audiovisual beyond 20 meters, reliability is relatively poor.
Be to provide a kind of in the purpose of utility model and utilize existing weak acoustic alarm device, can cut off the electricity supply automatically by day in order to avoid the synchronous alarm of antitheft strong acoustooptic of false alarm as the signal receiving element.
The purpose of the utility model realizes by following technology case.The synchronous alarm of a kind of antitheft strong acoustooptic, it is by Instrument shell, signal receiving element, signal control amplifying unit and alarm unit are formed, it is characterized in that being connected in series an optoelectronic switch K between signal receiving element and operating voltage, signal amplifies control module and comprises input end, power amplification circuit, power supply and output terminal.Input end is provided with transaudient S of piezoelectric type, and output terminal is provided with controllable silicon SCR.Warning lamp D in the alarm unit 3Separate installation with alert tinkling of pieces of jade F with Instrument shell.The power amplification circuit that signal of the present utility model amplifies in the control module is provided with a transformer B 2With two triode BG 1, BG 2Triode BG 2The collector series connection resistance R 4Back and triode BG 1Base stage link to each other an end of the main winding of transformer B and triode BG 2Base stage link to each other other end series resistor R 3Back and triode BG 1Emitter link to each other.
Accompanying drawing provides an embodiment of the present utility model.
Fig. 1 is a wiring diagram of the present utility model.
Fig. 2 amplifies the circuit diagram of control module for signal.
Below, embodiment in conjunction with the accompanying drawings is further described the utility model.
Supply voltage 220V holds to fuse IRD and optoelectronic switch K supply signal receiving element from L end and N, the signal receiving element is existing common burglar alarm, when at day, optoelectronic switch K, can cut off the power supply of signal receiving element automatically, make it to be in off working state, penetrate the generation that the district causes false alarm because of need of work enters the width of cloth to avoid the relevant personnel.When the curtain of night comes, museum closes door, optoelectronic switch K 1, just connect the operating voltage of signal receiving element automatically, make it to enter duty.In case have people's illegal invasion width of cloth to penetrate crime in the zone, the signal receiving element just can amplify control module to signal by the output alarm signal.Signal amplifies control module and comprises input end, power amplification circuit, power supply and output terminal.The input end that signal amplifies control module is provided with transaudient S of piezoelectric type, and it can receive special tonequality, both alarm sounds of signal receiving element, and this audio signal amplified to turn give power amplification circuit for voltage signal.In power amplification circuit, the collector series connection resistance R of triode BG 4With triode BG 1Base stage link to each other an end of the main winding of transformer B and triode BG 2Base stage link to each other other end series resistor R 3Back and triode BG 1Emitter link to each other.Why S receives alarm signal when piezoelectric type is transaudient, and when changing audio signal into voltage, makes triode BG 1, and BG 2Obtain bias voltage and conducting, electric current is through transformer B 2Coupling, at transformer B 2Secondary winding obtain a current signal after amplifying.Be provided with controllable silicon SCK at output terminal, it is being controlled and is coming from transformer B 1The break-make of the supply and AC power supply that coupling comes.When the current signal of power amplification control module output is delivered to the control utmost point of controllable silicon SCR, just trigger its conducting, thereby the 280V voltage that power supply is come is transported to the alarm unit of back through controllable silicon.Alarm unit is by A.C. contactor, compositions such as warning lamp and alarm bell, and the 220V alternating voltage that amplifies control module from signal makes relay factory J 1, J 2All electric, J 2Normally opened contact J 2-1, J 2-2 and the J-3 adhesive.Make alarm bell F and warning lamp D 3Acoustic luminous.Relay J gets electric, and its normally closed contact J-1 and J-2 decontrol, and makes to be installed in the interior relay indicating light D of duty room 1And D 2Because of outage is extinguished, the prompting operator on duty judges the crime spot, takes an immediate action.High light warning lamp D 3Be contained in the optimum position that to shine whole exhibition room.Strong sound alarm bell F should be contained in the highest top layer of buildings, imitates tired to strengthen its sound.2RD, 3RD are fuse.Except warning lamp D 3, alarm bell F and signal lamp D 1, D 2Outward, all the other components and parts are installed in the housing, are arranged on antitheft scene.In case of necessity, the power supply of available panel box is as working power of the present utility model.B 1Selecting power for use is the step-up transformer of 3W, B 2Adopt MY-979 type output transformer, BG 1, BG 2Adopt 3GD201 type triode.SCR is general 3A controllable silicon.
Compared with prior art, the utility model has the advantages that simple in structure, the functional reliability height, cost is low holds concurrently, and the general character is strong, can with existing warning, form general powerful momentum, cause a kind of fear psychologically for the perpetrator, force its spiritual pressurized, the action error has been created advantage for the security personnel arrests criminal. In addition, also can be with the alarm signal of fire protection warning phone 119 as signal receiving element of the present utility model, thereby for the Emergency Light in fire house, place with point out synchronously the rapid ready work of fire-fighting work personnel to gain time and provide convenience.
