According to the smell identification method, the smell identification system and the smell alarm system based on the electronic nose disclosed by the patent number CN 113341079B, the problem that the detection accuracy and the detection speed of the electronic nose are dependent on a smell identification algorithm applied to the electronic nose is mainly solved. In general, in the odor recognition algorithm, the magnitude of the response peak of each sensor to the target gas and the direction of the response peak are used as characteristic values, and then the characteristic values are distinguished by using a classification algorithm in machine learning, and classification calculation can be performed by using the shape of the whole response peak and a curve recovered after the response to the gas as characteristic values. The latter is rarely, if ever, employed because the efficiency of the algorithm is relatively low and it takes longer. For the former, the method of using the response peak value is usually to perform the value calculation at least when the sensor response to the target gas enters a steady state or maximum peak value. For either the resistive or electrochemical type gas sensor, it takes about two minutes to reach a steady state of response, and therefore, the time to start the value calculation is long, and the time to determine the target gas is long. If the maximum peak value is adopted for calculation, the time for starting the value calculation is longer, but the following problems still exist in the actual use process.
