Fig. 2 is the circuit structure schematic diagram of the combustible-gas detector of the present invention.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings：
As shown in Figure 1：The present invention include combustible-gas detector, Smoke Sensor, temperature sensor, information acquisition device,
A/D converter, central processing unit, transmitting set, radio receiver and warning device, the combustible-gas detector
The signal output part of signal output part, the signal output part of the Smoke Sensor and the temperature sensor is and described information
The signal input part connection of collector, the signal output part of described information collector pass through the A/D converter and the center
The signal input part connection of processor, the signal of the signal output part of the central processing unit and the transmitting set input
End connection, the signal output part wireless connection of the signal output part of the transmitting set and the radio receiver, institute
The signal output part for stating radio receiver is connected with the warning device.
Gas in Coal Mine hole, Smoke Sensor detection smog, temperature sensor are detected by combustible-gas detector
The temperature in ore deposit hole is detected, when these three signals produce any change, is alarmed, signal is gathered by information acquisition device,
A/D converter converts digital signals into analog signal, can send out central processing unit output signal by access in radio radio
Emitter, transmitting set are installed on outside ore deposit hole, so as to wirelessly be docked with radio receiver, avoid signal weak.
As shown in Figure 2：The combustible-gas detector is by gas sensor QM, first resistor R1, second resistance R2, the first electricity
Hold C1, the second electric capacity C2, diode VD, potentiometer RP and triode VT compositions.The first end of the gas sensor QM simultaneously with
The first end of heater strip connects with triode VT colelctor electrode in the positive pole of dc source, gas sensor QM, in gas sensor QM
Second end of heater strip is connected with first resistor R1 first end, gas sensor QM the second end while first with potentiometer RP
End, potentiometer RP sliding end, the first electric capacity C1 first end connect with second resistance R2 first end, and the of first resistor R1
Two ends connect with the negative pole of power supply, diode VD negative pole, the first electric capacity C1 the second end and the second electric capacity C2 first end simultaneously
Connect, potentiometer RP the second end is connected with diode VD positive pole, and second resistance R2 the second end is simultaneously with the second electric capacity C2's
