介绍了所研制的一个人工嗅觉装置,详细叙述该装置对呈香物质的识别过程。实验结果表明,采用SuperSAB 算法可以显著地提高人工嗅觉装置对香气物质的分析识别速度,为在线检测提供了条件,同时实验结果的准确性也较满意。关键词: 人工嗅觉系统;气体传感器阵列;前向神经网络;SuperSAB 算法Abstract : A new artificial olfaction device is introduced ,and the process of odorant recognition by this device is gone in details. The results for seven odor substances show that the super self2adapting back propagation (Super - SAB) algo2 rithm can effectively improve recognition speed of the presented device ,which creates conditions for real2time measure2 ment. And furthermore ,the recognition correction rate percent is satisfactory.Key words : artificial olfaction system;odor sensor array ;feed2forward neural networks ;SuperSAB algorithm
