Abstract
The utility model relates to an anti theft alarm circuit, which belongs to the electronic anti theft technology art. After being depressurized by the transformer, rectified by the bridge rectifier circuit and stabilized by the three terminal regulators, the 220V power source supplies power to the post circuit. The signal output end of the pyroelectric infrared sensor is connected with the foot 14 of the infrared processing application specific integrated circuit, the foot 2 of which is connected with the triode base by a resister. The triode emitter is connnected with the negative terminal of the power source, and a coil of a relay is connected between the triode collector and the positive terminal of the power source, which together with the power input end of the audio integrated chip is connected with the normally open contact of the relay. The signal output end of the audio integrated chip is connected with the triode base. The triode emitter is connnected with the negative terminal of the power source, and a loudspeaker is connected between the triode collector and the power input end of the audio integrated chip. As the technical proposal is adopted, the model has the advantages and effective results of audio alarm, good effects and low manufacture cost.
Description
Affiliated technical field
The utility model relates to a kind of anti-theft warning circuit, belongs to the electronic anti-theft technical field.
Background technology
At present, existing electronic anti-theft warning circuit has two kinds basically, and a kind of is the anti-theft warning circuit that utilizes the Doppler effect principle design, and a kind of is to utilize heat to release the anti-theft warning circuit of infrared sensor design, although can both play the burglar alarm effect, all be single chimes of doom.
Summary of the invention
The purpose of this utility model provides a kind of anti-theft warning circuit, and it is to utilize technical mature heat to release the infrared anti-theft alarm circuit and the language integrated chip combines, and when making anti-theft warning circuit work, directly barks out the sound of " catching a thief "
The purpose of this utility model is achieved in that circuit releases infrared sensor by heat, the infra red treatment special IC, the language integrated chip, resistance, electric capacity, transformer, three terminal regulator, triode, bridge rectifier circuit, relay, loudspeaker are formed, the 220V power supply is by the transformer step-down, the bridge rectifier circuit rectification, after the three terminal regulator voltage stabilizing backward the level circuit supply, resistance, annexation in the electric capacity by specification accompanying drawing connects, the signal output part that heat is released infrared sensor links to each other with 14 pin of infra red treatment special IC, it is characterized in that: 2 pin of infra red treatment special IC link to each other with the base stage of triode by resistance, the emitter of triode connects the negative pole of power supply, succeed the coil of electrical equipment between the collector of triode and the positive source, the power input of positive source and language integrated chip is succeeded the normally opened contact of electrical equipment, the signal output part of language integrated chip connects the base stage of triode, the emitter of triode connects the negative pole of power supply, connects loudspeaker between the integrated chip power input end of the collector of triode and language.Heat is released the model P288 of infrared sensor, the model of infra red treatment special IC SNS9201 SX-1, the model KD56029 of language integrated chip, the model 78L05 of three terminal regulator.The circuit original paper is welded in the circuit board according to the annexation in the Figure of description, and be placed in the suitable shell.
Because adopt technique scheme, the advantage and the good effect that are had are: language alarm, effective, cost is not high yet.
