摘　　要：针对冰箱贮存的肉类与蔬菜新鲜度检测需求,设计了基于智能电子鼻的新鲜度检测仪器。针对食品新鲜度特定气体的检测目标,设计了新型的气体传感器阵列,使用单片机及通信技术,研制出一台小型电子鼻仪器,实现了冰箱内食品信息的快速采集和检测以及数据通信功能。采用线性判别分析方法(LDA)及主成分分析(PCA)等算法实现了冰箱内食品种类和新鲜度的智能识别。在实际应用中,该仪器可根据冰箱保鲜贮存的特定低温环境,改进专用的检测气室和识别算法。In order to detect the freshness of refrigerator stored pork and vegetables, the design of freshness detection system based on intelligent electronic nose is proposed. Combined with the principal of MOS sensors array, the small size electronic nose system is to be built with single chip microcomputer and its communication function, which achieves the goal of fast detection, data communication, using Linear Discriminant Analysis （LDA） and Linear Discriminant Analysis （PCA） method to identify the freshness and classify different kind of food. According to the low-temperature circumstance of refrigerator, special detection chamber and methods are improved.
