Several Data Analysis And Processing of Electronic Nose Data Preprocessing Subsystem

Electronic nose is a kind of system that imitates biological olfactory organs. It uses different response sequences of gas sensor array to identify gas The electronic nose system consists of gas sensor array subsystem, electronic nose data analysis subsystem, electronic nose pattern recognition subsystem and electronic nose result discrimination subsystem. The development of electronic nose has two significant directions: miniaturization and systematization. This paper introduces the functions and components of the electronic nose system, focusing on several data analysis of process in the electronic nose system. There are mainly k-nearest neighbor, linear discriminant, principal component analysis and cluster analysis. The processing characteristics of these methods are analyzed and explained.
