Abstract
The utility model relates to a theftproof strong acoustooptic synchronous alarm which is composed of an instrument casing, a receiving unit, a signal amplification control unit and an alarming unit, wherein a photoelectric switch K is connected in series between the signal receiving unit and operating voltage; the signal amplification control unit comprises an input terminal, an output terminal, a power amplifying circuit and a power supply. 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
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.
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.
