Embodiment Construction
[0055] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0056] Before introducing the scheme of this application, the previous research work of the inventor of this case is introduced.
[0057] The inventors of this case found through experimental research that, for a single odor molecule, the response signal strength of the electronic nose sensor can be expressed as:
[0058] s=γm
[0059] Among them, s is the total response value of the sensor to the odor molecule A, and m is the total adsorption amount of the odor molecule A, which i...

The invention discloses a method and a device for identifying a tobacco essence. The method only comprises the following steps: obtaining transient response signal values of t measurement points of an electronic nose sensor array for volatile components of a to-be-identified tobacco essence; building a response matrix R by employing the obtained values, and carrying out factorization on the response matrix R, so as to obtain an adsorption quality form matrix C, an adsorption quality coefficient matrix N and an odor characteristic matrix gamma; and further treating the three matrixes to obtain a plurality of three-dimensional stereograms of odor maps for representing the to-be-identified tobacco essence, comparing with the odor maps and the corresponding relationships between the preset tobacco essence type and the odor maps, so as to determine the type of the to-be-identified tobacco essence. According to the method disclosed by the invention, identification for the tobacco essence is carried out by virtue of software program, so that the problems of high cost and long identification time, caused by an artificial smoke panel test, are avoided; and lots of experiments prove that the identification efficiency for the tobacco essence is very high.
Description
technical field [0001] The present application relates to the technical field of odor identification, and more specifically, to a method and device for identifying tobacco flavor. Background technique [0002] Tobacco essence can play the role of flavoring and seasoning to cigarettes, and endow cigarettes with a certain characteristic fragrance. The existing tobacco flavor identification process is mainly identified through the sense of smell of the sensory evaluation personnel. [0003] However, this existing evaluation method not only brings subjective differences to the evaluation of the quality of tobacco flavors, but also needs to organize a number of personnel with qualification certificates to carry out the identification of tobacco flavors, resulting in the identification of tobacco flavors. Problems that cost a lot and take a long time to identify. Contents of the invention [0004] In view of this, the present application provides a method and device for identi...
