The working principle of the invention is: in temperature detecting module, the electric current of power supply VCC output passes through by chip IC 1, chip
Power after the constant-current source circuit of IC2 and its peripheral components composition to thermistor RS, the resistance value of thermistor RS with temperature change
Change and changes, so that the input voltage of 4 pin 2 of chip IC is influenced, when the temperature in monitoring area is higher than setting value, chip
The input voltage of IC4 is high level, and chip IC 2 is temperature signal buffer stage, and chip IC 3 is that temperature signal lags comparative degree, right
By thermistor feedback Lai voltage signal clamped down on, warning circuit will not work immediately, prevent opening repeatedly for warning circuit
It opens and turns off, reduce the aging speed of component, only after the environment temperature in monitoring area is lower than setting value for a period of time,
High level signal OUT1 is exported to single-chip microcontroller Master Control Center by 3 pins of chip IC 4, and single-chip microcontroller Master Control Center passes through
Coder-decoder inside STC89C52 single chip is analyzed and processed alarm signal, and exports to pinhole cameras, control
The unlatching of monitoring device, records the voice and image information of monitoring area, and will trigger information by GPRS module and be transferred to and make
The mobile phone and fire department of user, while combined aural and visual alarm is opened, short-distance alarm signal is issued, reminds neighbouring miner timely
It withdraws.
In Smoke Detection module, when non smoke in monitoring area, starting of the infrared light-emitting diode D1 to mix up in advance
Galvanoluminescence.The infrared light reduces its internal resistance after being received by phototriode VT1, so that infrared light-emitting diode D1 and photosensitive
Electric current in triode VT1 series circuit increases, and the luminous intensity of infrared light-emitting diode VD1 increases accordingly, phototriode
VT1 internal resistance further decreases.So circulation just forms strong positive feedback process, until making the electric current in series connection photosensitive circuit
Reach maximum value, triode VT2 is connected through diode D2 in the pressure drop generated on resistance R1, triode VT3 cut-off, alarm
Circuit does not work.When the hurried increase of the smog in monitoring area, the translucency in air deteriorates, at this time phototriode VT1
The luminous flux received reduces, and internal resistance increases, and the electric current in photosensitive circuit of connecting also reduces therewith, the hair of light emitting diode D1
Luminous intensity also weakens therewith.The process for just foring negative-feedback is so recycled, makes the electric current in series connection photosensitive circuit until reducing
To initial current value, the voltage on resistance R9 also drops to critical value, and triode VT2 is connected, and issues alarm signal OUT2 to singly
Pian Ji control centre, it is identical when subsequent processing mode is with above-mentioned temperature alarming.Any one triggering of two ways will trigger report
Alert circuit.
System monitors monitoring area in real time using temperature and smog double check mode, when encountering fire condition,
The image information of alarm region can also be acquired, and is sent remotely to mobile phone and the fire-fighting portion of user by Internet of Things GPRS module
Door, greatly reduces the fire rescue time, therefore system has the advantages that precision is high, vdiverse in function and monitoring effect is good.
