Description

technical field [0001] The invention belongs to the fields of electronic information, artificial intelligence, sensor technology and gas detection, and in particular relates to an artificial intelligence olfactory dynamic response map gas detection and identification method. Background technique [0002] The detection and identification of trace gas is widely used in chemical industry, food, environment and other fields, so fast and accurate trace gas detection method is especially important. Traditional gas detection methods rely on a single gas sensor based on physical and chemical principles, such as metal-semiconductor gas sensors, electrochemical gas sensors, infrared gas sensors, and gas sensors based on magnetic properties. Sensors generally have cross-sensitivity, poor stability and selectivity, and the response characteristics are easily affected by environmental factors such as temperature and humidity. Moreover, accurate qualitative and quantitative identification...
