Mist type, and then according to above-mentioned corresponding relationship, obtain real-time smog type.For example, in water mist 2.5um or more bulky grain pole
It is few.If including the bulky grain of a large amount of 2.5um or more in current smog, show that current smog is not water mist.
2) according to the corresponding relationship of preset smoke particle peak concentration and smog type, smog type information is obtained.
Specifically, different smoke particle peak concentrations correspond to different smog types.For example, decocting the granule density peak of beefsteak
Value and the peak concentration of fire are different, so as to distinguish pan-fried beefsteak smog and fire hazard aerosol fog.
3) according to the corresponding relationship of preset smoke particle concentration pace of change and smog type, smog type letter is obtained
Breath.
Specifically, different smoke particle concentration paces of change corresponds to different smog types.For example, the smog of fire
The grain concentration rate of climb is exceedingly fast, and size particles mist has；The smoke particle concentration rate of climb of cigarette is slow, and little particle is more, thus
Fire hazard aerosol fog and smoke from cigarette can be distinguished.
Judgment module 23 is used to be judged whether according to the smog type information to issue alarm.
Specifically, according to acquired smog type information, judge whether it is the smog type for needing to alarm；If so,
Issue alarm；If it is not, then without alarm.For example, not issuing alarm then when the smog type information is smoke from cigarette；When
When the smog type information is fire hazard aerosol fog, then alarm is issued；When the smog type information is to decoct beefsteak smog, then not
Issue alarm.Therefore, by acquired smog type information, smog alarm can be efficiently sent out, avoids the hair of false alarm
