Analyzing and processing, and export to relay module, relay module can open heating tube or refrigerator pipes according to the signal of input,
Temperature inside machine room is regulated and controled.
When machine room inside non smoke, infrarede emitting diode D1 is lighted with the initial current for mixing up in advance.The infrared light
Reduce its internal resistance after being received by phototriode VT1 so that infrarede emitting diode D1 and phototriode VT1 series circuits
In electric current increase, the luminous intensity of infrarede emitting diode VD1 accordingly increases, and phototriode VT1 internal resistances further reduce.
So circulation just defines strong positive feedback process, until make the electric current in series connection photosensitive circuit reach maximum, in resistance
The pressure drop Jing diode D2 produced on R1 turn on audion VT2, and audion VT3 cut-offs, warning circuit does not work.Work as high-voltage line
In neighbouring environment during the hurried increase of smog, the light transmission in air deteriorates, the luminous flux that now phototriode VT1 is received
Reduce, its internal resistance increase, the electric current connected in photosensitive circuit also reduces therewith, and the luminous intensity of light emitting diode D1 also subtracts therewith
It is weak.So circulation just defines degenerative process, makes the electric current in series connection photosensitive circuit until being reduced to initial current value, electricity
Voltage on resistance R9 also drops to marginal value, turns on audion VT2, sends alarm signal in the second A/D converter, the 2nd A/
D transducers are processed input signal, are converted into being transferred to single-chip microcomputer, an A/ after the machine language that single-chip microcomputer is capable of identify that
