Abstract
The present invention relates to chemical industry fire protection technologies fields, refer specifically to a kind of chemical industry fire fuel identification method based on combustion product, its step are as follows：A, the incendivity object sample for choosing the higher chemical of purity, sample is put into smoke generating apptss and is burnt, and the flue gas that burning is generated inputs mixing arrangement；B, the flue gas of mixing in mixing arrangement is inputted several light rooms, the acquisition indoor direct light of light and scattering light by capillary is influenced generated change in radiation intensity data by flue gas；C, it enters data into the database of computer foundation, randomly selects the partial data in database as training set, be trained by Randomforest algorithms, then training set is tested to determine validity with remaining data；The influence for the flue gas centering long wave light that the present invention is generated by the different comburants of identification, collecting sample data establish large database concept, learnt by Randomforest machine algorithms, realize the quick analysis and response of scene of a fire comburant, reduces the risk and rescue difficulty of chemical industry fire.
Description
Technical field
The present invention relates to chemical industry fire protection technologies fields, refer specifically to a kind of chemical industry fire fuel knowledge based on combustion product
Other method.
Background technology
Due to the complexity that chemical industry place article is placed, once it is difficult quick identification fire source and fuel kind that fire, which occurs,
Class.Such as in the event of PORT OF TIANJIN, due to lacking the understanding for explosive category, fire fighter takes incorrect fire extinguishing side
Method results in the casualties and property loss of bigger.Therefore the quick determination for fire cause class, especially fuel type
It quickly determines for controlling fire behavior, it is most important to reduce loss.Since the burn incompletely of fuel inherently produces in fire process
Raw a large amount of flue gas, and numerous studies show flue gas caused by different types of fuel in color, temperature, grain size, surface shape
State and density etc. are all different, and therefore, it is necessary to a kind of technologies that fire fuel can be identified by flue gas, for fire
The quick emergency response at calamity scene.
Invention content
In view of the defects and deficiencies of the prior art, the present invention intends to provide one kind can recognizing different flue gases to difference
The direct projection and scattering of wavelength light influence, and establish large database concept and carry out Randomforest training, improve burning things which may cause a fire disaster resolution and sound
Speed is answered, the chemical industry fire fuel identification method based on combustion product of chemical industry fire risk is reduced.
To achieve the goals above, the present invention uses following technical scheme：
A kind of chemical industry fire fuel identification method based on combustion product of the present invention, its step are as follows：
A, the incendivity object sample for choosing the higher chemical of purity, sample is put into smoke generating apptss and is burnt, so
Start the flue gas that the first fan in smoke generating apptss generates burning afterwards and inputs mixing arrangement；
B, the first fan is closed, the flue gas of mixing in mixing arrangement is passed through capillary by the second fan started in mixing arrangement
Pipe inputs several light rooms, the acquisition indoor direct light of light and scattering light is influenced generated change in radiation intensity data by flue gas；
C, it enters data into the database of computer foundation, randomly selects the partial data in database as training
Collection, is trained, then tested training set with determination with remaining data in database by Randomforest algorithms
Validity.
According to above scheme, the mixing arrangement is separately connected 10 identical light rooms, and 10 by 10 capillaries
The middle long wave light of 10 kind different wave lengths of the wave-length coverage between 275nm-930nm is respectively adopted in light room.
According to above scheme, the light room includes straight line chamber, light source, scattered light sensor and direct projection optical sensor, light
It is equipped with lens on front side of source outgoing plane, scattered light sensor and direct projection optical sensor.
According to above scheme, any indoor direct light of light and scattering light convert the equal synchronous transfer of data to database
It is interior to keep the consistency of data.
According to above scheme, the air intake of the smoke generating apptss is equipped with HEPA filters.
The present invention has the beneficial effect that：The shadow for the flue gas centering long wave light that the present invention is generated by the different comburants of identification
It rings, collecting sample data are established large database concept, learnt by Randomforest machine algorithms, realize the quick of scene of a fire comburant
Analysis and response reduce the risk and rescue difficulty of chemical industry fire.
