WANG Wei-wei, ZHANG Sai-nan. Electronic nose system based on PCA and BP hybrid neural network algorithm[J]. 2014, 33(4): 90-92. DOI: 10.13873/j.1000-97872014.04.043.
through hardware design scheme consists of data acquisition module and microprocessor module
an electrical noise system is designed and developed based on six kinds of Figaro metal-oxide gas sensor array for real time food non-destructive examination( NDE). As for the software design scheme
the principal component analysis( PCA) and back propagation( BP) are utilized and used to analyze gas"fingerprint information"database by LabVIEW. The experimental results show that the designed electronic nose system can distinguish different types of vinegar accurately
and provide a convenient method for vinegar quality evaluation.
