Study on the development of a practical system for discrimination and concentration-estimation of domestic gases

摘要

Agas discrimination system which can estimate the concentration of the discriminated gases are proposed in this paper. TMS320C50 DSP by Texas Instruments and semiconductor gas sensor TGS823 by FIGARO Electronic are utilized for a data processing unit and a sensing probe, respectively. As for software, an artificial neural network and a fuzzy-neural network are used for the discrimination and the concentration- estimation of introduced gases, respectively.
