Abstract

The invention discloses an odor concentration OU value algorithm based on a multi-component gas detector sensor array, and the algorithm comprises the steps: building an odor concentration OU value calculation formula in multiple scenes based on a combined variable, a specific gravity coefficient and a comprehensive adjustment coefficient; acquiring each gas concentration value acquired in the multi-component gas detector sensor array; determining an application scene; and according to the application scene, substituting the obtained gas concentration values into an odor concentration OU valuecalculation formula in the corresponding scene to obtain an odor concentration OU value. According to the invention, a PLS mathematical analysis model is established without artificial olfactory discrimination of result values; the odor concentration OU value of the actual environment is directly calculated according to the theoretical olfaction threshold parameter of the odor key gas factor in combination with the empirical coefficient of the application scene; according to the method, subjective interference and instrument debugging cost are reduced, monitoring results are objective, data results of the same application scene have uniformity and comparability, the calculation process is simple and visual, and the goodness of fit with odor concentration theoretical results is high.

Description

technical field [0001] The present application relates to the technical field of gas detection, in particular, to an algorithm of odor concentration OU value based on a sensor array of a multi-component gas detector. Background technique [0002] At present, the known method for calculating the OU value of the odor concentration is the classic artificial three-point comparative olfactory identification method, that is, through a group of sniffer noses, each sniffer gradually Dilute to no smell, the multiple of gas dilution is the odor concentration value, the olfactory identification results (dilution multiples) of each of the 5 sniffers take the logarithm Lg with a base of 10 and then take the average value, Then use this average value to take the anti logarithm of base 10 to calculate, and the calculated result is the standard three-point comparison formula to smell and distinguish the odor concentration result value. Although this method is a national standard method, it...
