Paper Abstract

12 Infrared absorption method in analyzing gas components is a traditional spectrum analyzing method of gas. Nevertheless, the distribution of the absorption spectrum of a certain kind of gas intercrosses with another's, which means that the absorption peaks of two kinds of gases are near very close. So, when those kinds of gases aforementioned are mixed together, the spectrum analysis will have the cross sensitivity. In this paper, the genetic neural network algorithm is adopted to recognize the patterns of the mixed gases with three components in the simulation recognition. The genetic algorithm decreases the cross sensitivity of the gas sensor. Especially the staged-sectional method is used to increase the recognition accuracy of various over-limit value.
