Multi-component gas detection method and device based on electronic nose system

The invention provides a multi-component gas detection method and device based on an electronic nose system, and the method comprises the steps: collecting a multi-component gas sample through the electronic nose system, carrying out the gas type recognition of the multi-component gas sample, obtaining a recognition result of the multi-component gas sample, and collecting the multi-component gas sample as a training set; under the condition that the gas types of the multi-component gas samples are determined, the test set is input into a trained mixed neural network, a two-dimensional detection result of the test set is obtained, and the two-dimensional detection result comprises the gas concentration of each dimension of gas in the multi-component gas samples corresponding to the test set. According to the invention, multi-distance concentration detection of the multi-component gas can be realized, so that the detection accuracy and the detection efficiency of the multi-component gas sample are improved. 本发明
