Problems solved by technology

[0003] The traditional classification of single-clump tea aroma types is mainly achieved through manual review, which requires damage detection of samples
Moreover, the results of manual review are affected by the subjective consciousness and physiological state of the reviewers, which is not conducive to obtaining high-precision and repeatable test results
Among the detection methods for tea aroma types, there is no technology and method that can quickly classify the aroma types of single-clump tea

Abstract

The invention relates to a single-cluster tea aroma type classification method and device based on bionic olfaction, computer equipment and a storage medium. The method comprises the following steps:collecting a correction sample set of single cluster tea leaves; wherein the correction sample set comprises a plurality of correction samples of single cluster tea leaves with different aroma types;an electronic nose with a sensor array is used for collecting a time sequence sensing signal generated when volatile matter gas of the calibration sample reacts with the sensor array; characteristic variable values are extracted from the time sequence sensing signals, and a characteristic variable matrix is constructed after standardized preprocessing is conducted on the characteristic variable values; and constructing a single-cluster tea aroma type classification model according to the characteristic variable matrix in combination with the aroma type label of the correction sample. By adopting the method, aroma type classification can be quickly and efficiently carried out on single cluster tea leaf samples.

Description

technical field [0001] The present application relates to the technical field of quality detection, in particular to a method, device, computer equipment and storage medium for classifying single-clump tea aroma types based on bionic sense of smell. Background technique [0002] Dancong tea is one of the three most fragrant teas in the world, mainly produced in Chaozhou City, Guangdong Province, China. According to the data in 2018, the planting area of ​​Dancong tea in Chaozhou reached 193,000 mu, the total output of tea was 24,000 tons, and the output value exceeded 3.5 billion yuan. For example, Chaozhou flower-flavored "Fenghuang Dancong Tea" and honey-flavored "Lingtou Dancong Tea" are the two main products in the region, both of which were granted geographical indication protection in 2013. In order to improve the benefits of Dancong tea industry, in the process of realizing the modernization and large-scale production of Dancong tea, ensuring the quality of aroma typ...
