Master control cpu is the signal processing unit of core component based on stc89c52 single-chip microcomputer.
Dual power supply module is combined by line voltage and accumulator and forms.
The operation principle of the present invention is: as shown in Figure 2: in temperature detecting module, the electric current of power supply vcc output passes through by core
Power to critesistor rs after the constant-current source circuit of piece ic1, chip ic2 and its peripheral components composition, the resistance of critesistor rs
Variation with temperature and change, thus affecting the input voltage of chip ic4 pin 2, when the temperature in monitor area be higher than set
During value, the input voltage of chip ic4 is high level, and chip ic2 is temperature signal buffer stage, and chip ic3 is that temperature signal is delayed
Comparative degree, clamps down on to feeding back, by critesistor, the voltage signal coming, warning circuit will not work immediately, prevents warning circuit
Be repeatedly switched on and off, reduce components and parts aging speed, only when the ambient temperature in monitor area be less than setting value one
After the section time, it is added on buzzer b so that buzzer b sends out by 3 pin output high level signal out1 parts of chip ic4
Go out chimes of doom, this signal is also transmitted to master control cpu, master control cpu simultaneously, by the coder-decoder within stc89c52 single-chip microcomputer
Alarm signal is analyzed process, and exports to electromagnetic valve, foam spray is opened by electromagnetic valve, reaches emergent fire extinguishing work(
Can, small-sized fire suppression also can there be is certain interception to large-sized fire, system will trigger also by gprs module
Information transfer is to the mobile phone of user and fire department.
As shown in Figure 3: in Smoke Detection module, when non smoke in monitor area, infrarede emitting diode d1 is with advance
The initial current mixing up lights.This infrared light is made its internal resistance reduction so that infraluminescence two pole after phototriode vt1 reception
Electric current in pipe d1 and phototriode vt1 series circuit increases, and the luminous intensity of infrarede emitting diode vd1 accordingly increases,
Phototriode vt1 internal resistance reduces further.So circulation just defines strong positive feedback process, until making the photosensitive electricity of series connection
Electric current in road reaches maximum, and the pressure drop producing on resistance r1 makes audion vt2 turn on through diode d2, audion vt3
Cut-off, warning circuit does not work.When the hurried increase of the smog in monitor area, the light transmission of in the air deteriorates, now photosensitive
The luminous flux that audion vt1 receives reduces, and its internal resistance increases, and the electric current in series connection photosensitive circuit also reduces therewith, and luminous two
The luminous intensity of pole pipe d1 also weakens therewith.So circulation just defines degenerative process, makes the electricity in series connection photosensitive circuit
Until being reduced to initial current value, the voltage on resistance r9 also drops to marginal value to stream, so that audion vt29 is turned on, sends alarm signal
Number out2 to master control cpu, subsequent treatment mode is identical when reporting to the police with said temperature.Any one triggering of two ways will trigger
Warning circuit.
System carries out monitor in real time using temperature and smog double check mode to monitor area, when running into fire condition,
Extinguishing device can also be automatically turned on, effectively reduce spreading of the intensity of a fire, and user is sent remotely to by Internet of Things gprs module
