The Research on Artificial Olfaction System-Electronic Nose

摘要

This paper has presented an artificial olfactory system, based on the structure and mechanism of biological olfactory system. The main goal of our study was to expound the principle of olfaction system of human body. It has complex structure model and of which structure and mechanism still under exploration. We built the model of sensory system mechanism, depicted the olfactory mechanism of the olfactory, and compared the different methods of pattern recognition. The result will show that the SOM method of pattern recognition accord by and large with human mode, and is better than the BP neural network.
