Embodiment 4
One of embodiments of the present invention, the main technical schemes and embodiment 1,2 or 3 of the present embodiment are essentially identical,
The feature not laid down a definition in the present embodiment is no longer repeated herein using the explanation in embodiment 1,2 or 3.The present embodiment with
The difference of embodiment 1,2 or 3 is:
The laser beam of the Laser emission end transmitting is three color laser beams, and the three color laser beams are R, G, B color beam；
The laser pick-off end is for receiving the three color laser beams from Laser emission end, and the optical sensor is according to reception
Three color laser beams generate laser signal, the laser signal is the spectral signal for carrying three color laser beams spectral information；
The laser electronic control module receives the spectral signal from laser pick-off end；
In the present embodiment, the laser electronic control module is also stored with pre-set oily refractive index threshold value and water refractive index
Threshold value；The laser electronic control module calculates actual refractive index according to spectral signal, and actual refractive index and oil smoke ingredient are rolled over
The rate of penetrating is compared judgement, generates oil component signal or water constituent signal；
If the actual refractive index is in oily refractive index threshold range, oil component signal is generated.Illustrate in the oil smoke
In, oil component content is larger, and biggish wind speed is needed to absorb it；
If the actual refractive index is in oily refractive index threshold range, water constituent signal is generated.Illustrate in the oil smoke
In, water constituent content is larger, is absorbed using lesser wind speed to it；
The controller is for receiving oil component signal or water constituent signal from laser electronic control module；And according to being connect
The signal of receipts generates the speed considerations factor or revolving speed deceleration parameter, and sends it to blower electronic control module, enhancing or reduction wind
Speed.
If controller receives oil component signal, the speed considerations factor is generated, and by speed considerations factor blower electronic control module,
Enhance wind speed.
If controller receives water constituent signal, revolving speed deceleration parameter is generated, and by revolving speed deceleration parameter blower electronic control module,
Reduce wind speed.
