In specific implementation process, the air near 1 fetching portion smoke exhaust ventilator of air acquisition module, and air is transmitted
Into operational module 2, air is transmitted to compression submodule 21 by operational module 2, and compression submodule 21 compresses air, should
Compression process is gradually to carry out Real Time Compression, is gradually increased in the atmospheric density for being subjected to real-time successional compression, unit bodies
The turbidity of air gradually increases in product, and the weak light source that light source submodule 22 emits is in the air to gradually reduce in unit volume
It is interior to be influenced by more impurity, cause weak light source when propagating to receiving submodule 23, receiving submodule 23 receives
The target light light intensity that sends out of weak light source become smaller.Since compression process is continuing always, receiving submodule 23 receives obtained mesh
Mark light light intensity persistently reduces.In the process, computing module constantly carries out mesh according to the target light that receiving submodule 23 receives
The calculating of light light intensity is marked, and result of calculation is transmitted to processing module 3.When compressing 21 continuous compressed gas of submodule,
Compression module sends Real Time Compression degree to processing module 3.Processing module 3 is using Real Time Compression degree as abscissa, by target light reality
Time is pretended draws plane coordinate system for ordinate, and the Real Time Compression degree and target light that are received according to each time point are real-time
Light intensity carries out the drafting of the real-time light intensity curve graph of target light.After completing, processing module 3 calculates real-time according to derivative theorem
The corresponding differential numerical value in each position on light intensity curve, the target light of the differential numerical value, that is, weak light source transmitting is in current real-time ring
Degree of change under border.There are the real-time degree of change of target light light intensity under normal air state, processing module 3 in processing module 3
The deviation of the real-time degree of change of target light under present air state is carried out according to the real-time degree of change of target light under normal air state

Reference chart is Fig. 1, Fig. 3.For embodiment one, the difference of the present embodiment is：
Be provided under normal air state as a kind of preferred embodiment of the present invention, in the processing module 3, target light via
In compression 21 compressed air of submodule when traveling to receiving submodule 23, mesh that processing module 3 is measured according to reaction module 4
Mark the target distribution curve flux that the real-time light intensity of light is drawn.
As a kind of preferred embodiment of the present invention, the processing module 3 is by the target distribution curve flux under normal air state
Overlapped in the same coordinate system with the target distribution curve flux under present air state, the processing module 3 according to curve graph into
The judgement of row curve location relationship, the control module 5 carry out the manipulation of system according to the judging result.
In specific implementation process, when processing module 3 judges that current goal light curve is located at below normal target light curve
When, processing module 3 judges that current air mass is poor, and system works；When processing module 3 judges the current goal light
When curve has intersection point with the normal target light curve, processing module 3 calculates current goal light curve and is located at normal target
The area in the section of light curve lower section and top, and judge size, under the area that judgement is located above is more than and is located at
When the area of side, processing module 3 judges under the current working efficiency of smoke exhaust ventilator that oil smoke will not be accumulated；When judgement is located above
Area be less than underlying area when, processing module 3 judges under the current working efficiency of smoke exhaust ventilator that oil smoke can be accumulated,
The judgement of processing module 3 needs to increase working efficiency, and processing module 3 increases to 5 transmission power of control module to be instructed, control module 5
Increase the lampblack-pumped dynamics of smoke exhaust ventilator.
