摘要
研制了一套由51单片机和厚膜传感器阵列组成的电子鼻系统,并介绍了该系统的工作原理。对不同气体通过传感器阵列产生的响应信号进行了数据采集,利用BP神经网络对样本进行分析识别,并在显示终端实现气体成分的定性或定量显示。
An electronic nose system made up by 51 single-chip microcomputer and thick film sensors is developed.And the working principle of the system is introduced.The response signal is collected from different gas sensors.Samples of the gases are identified and analyzed by BP neural network.In the end,the results of analysis about gas composition will be displayed by qualitative and quantitative methods.
