Abstract

The utility model relates to an intelligent fire-fighting detection module which comprises a smog sensor circuit and a single chip control circuit, wherein an output signal of the smog sensor circuit is transmitted to the single chip control circuit through a trigger circuit; an output signal control of the single chip control circuit is sent to a carrier signal phase-locking circuit; and the output signal of the carrier signal phase-locking circuit is sent to a frequency-selecting amplifying emission circuit. An electric carrier mode is adopted for alarming by the intelligent fire-fighting detection module, namely, an electric carrier alarming mode is realized without utilizing professional wiring; when a fire disaster happens and the smog is sensed by a smog sensor, a single chip is utilized to judge, and then a carrier signal is sent by the electric carrier, an alarming signal is received by a carrier host machine, and an acousto-optic alarm is sent for reminding an operator on duty of the fire disaster.

Description

Intelligent fire-fighting detection module

Technical field

The utility model relates to a kind of detection module, particularly be a kind of intelligent fire-fighting detection module.

Background technology

Existing fire alarm system, major part are to report to the police through the wired alarming pattern, and it connects up complicated, and will destroy original structure, but at some special occasions, just can not destroy original structure and outward appearance like ancient building.

The utility model content

The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of intelligent fire-fighting detection module is provided.

The utility model solves the technical scheme that its technical matters adopted: intelligent fire-fighting detection module; Comprise smoke transducer circuit and single chip machine controlling circuit; The output signal of said smoke transducer circuit transfers to single chip machine controlling circuit through trigger circuit; The output signal controlling of said single chip machine controlling circuit is sent to the carrier signal phase lock circuitry, and the output signal of carrier signal phase lock circuitry sends to the frequency-selecting amplification emissioning circuit.

Preferably, said smoke transducer circuit adopts TGS-202 smoke transducer IC1 to gather smoke signal, and its output terminal is connected with resistance R 1, R2.

Preferably, said trigger circuit are made up of resistance R 3, the adjustable potentiometer KP that 2N6028 unijunction transistor VT and output terminal thereof connect.

Preferably, said carrier signal phase lock circuitry 21 is made up of LM567 tone decoder IC3 and peripheral capacitor C 4, resistance R 6, resistance R 7 thereof.

Preferably, said frequency-selecting amplification emissioning circuit is made up of elementary L1, capacitor C 5, the capacitor C6 of triode VT1, audio-frequency transformer (AFT) T, and its secondary L2 through audio-frequency transformer (AFT) T, capacitor C 7 are sent data-signal to the carrier wave main frame.

Through adopting above-mentioned technical scheme, the beneficial effect of the utility model is: the utility model adopts the power carrier mode to report to the police, and promptly need not specialty connect up; Realize through the power carrier alarm mode, when breaking out of fire, when smoke transducer is sensed smog; After the single-chip microcomputer judgement, send carrier signal through power carrier, the carrier wave main frame receives alerting signal; Send sound and light alarm, remind the operator on duty that fire has taken place.

Fig. 2 is the circuit theory diagrams of the utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is done further to specify.

Like Fig. 1, shown in Figure 2; The intelligent fire-fighting detection module of the utility model; Comprise smoke transducer circuit 1 and single chip machine controlling circuit 2; The output signal of said smoke transducer circuit 1 transfers to single chip machine controlling circuit 2 through trigger circuit 11, and the output signal controlling of said single chip machine controlling circuit 2 is sent to carrier signal phase lock circuitry 21, and the output signal of carrier signal phase lock circuitry 21 sends to frequency-selecting amplification emissioning circuit 22.

Said smoke transducer circuit 1 adopts TGS-202 smoke transducer IC1 to gather smoke signal; Its output terminal is connected with resistance R 1, R2; Said trigger circuit 11 are made up of resistance R 3, the adjustable potentiometer KP that 2N6028 unijunction transistor VT and output terminal thereof connect, and this circuit has adopted the mode of DC heating.When gas or smokescope increase, TGS-202 smoke transducer IC1 internal resistance step-down, A point current potential rises rapidly; After the time-delay of resistance R 1, capacitor C 1 integration, the 2N6028 unijunction transistor VT conducting that is triggered forms a positive step signal on resistance R 3; Because 2N6028 unijunction transistor VT conducting is isolated the output low-potential signal through diode VD1, this signal is input to the 34th pin I/O end of single-chip microcomputer IC2; After single-chip microcomputer IC2 judgment processing; By the carrier signal phase lock circuitry 21 that LM567 tone decoder IC3 and peripheral capacitor C 4, resistance R 6, resistance R 7 thereof constitute, its oscillation frequency is by the parameter determining of capacitor C 4, resistance R 6, and carrier frequency is adjusted in the 150-300KHZ scope; Elementary L1, capacitor C 5, capacitor C6 by triode VT1, audio-frequency transformer (AFT) T constitute frequency-selecting amplification emissioning circuit 22; The 2nd pin output high level signal by single-chip microcomputer IC2 makes LM567 tone decoder IC3 obtain working power, and LM567 tone decoder IC3 starts working; Be coupled on local telephone network speaking wire or the AC network AC220V power lead and send by secondary L2, the capacitor C 7 of audio-frequency transformer (AFT) T, send data-signal to the carrier wave main frame.After the carrier wave main frame received information, display alarm address azimuth information was reminded the operator on duty, and breaking out of fire should arrive on-the-spot fire extinguishing.

An above-described preferred embodiment that is merely the utility model can not limit the scope that the utility model is implemented, and every equalization of being done according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
