Abstract

The invention discloses an odor recognition method based on machine sense of smell, comprising: acquiring a mixed response signal of a target mixed odor; judging whether there is an unknown response signal in the mixed response signal; if so, filtering out the unknown response signal from the mixed response signal, Obtain the target response signal, compare the target response signal with the template response signal in the preset database, and determine the odor type and content corresponding to the target response signal. Before processing the mixed response signals of mixed odors, the method first filters out the unknown response signals in the mixed response signals to avoid the impact of unknown odors on the recognition results, thereby improving the recognition efficiency, accuracy and the precision of odor quantitative analysis. Correspondingly, an odor recognition device, device and computer-readable storage medium based on machine sense of smell disclosed in the present invention also have the above-mentioned technical effects.

Description

technical field [0001] The present invention relates to the technical field of artificial intelligence, and more particularly, to a method, device, device and computer-readable storage medium for odor identification based on machine smell. Background technique [0002] At present, the application of machine olfactory technology is becoming more and more extensive, and there have been a large number of application cases in industrial gas monitoring, chemical product quality monitoring, indoor and outdoor environmental monitoring, medical diagnosis, identification of Chinese medicinal materials, etc. [0003] In these application fields, the monitored odors are mostly mixed odors, and the odor information in the electronic nose database is limited, so there must be unknown gases. In addition, the existing odor recognition technology does not consider the influence of unknown odors on the recognition result when processing the response signal of the sensor, which leads to a lar...
