基于天牛检测的电子鼻系统设计

Design of Electronic Nose System Based on the Detection of Longicorn

天牛是危害园林植物的主要害虫之一,植物被侵害后会产生气体。本文基于电化学气体传感器阵列、信号调理、数据采集及计算机Labview处理模块设计构建电子鼻系统;并介绍了系统的总体结构,传感器阵列、硬件电路、软件设计;最后通过配置不同气体对系统进行了定性识别实验,结果表明,所设计的电子鼻系统对天牛所产生的气体辨识率可达90%以上。

Beetle is one of the main pests of garden plants,the plant will produce gas after the invasion.In this paper,the electrochemical gas sensor array,signal conditioning,data acquisition and computer Labview processing module design based on electronic nose system construction;and introduces the overall structure of the system,the design of hardware circuit,software and sensor array;finally through the allocation of different gases on the system of the qualitative recognition experiment,the results show that the electronic nose system design institute the longicorn gas identification rate is more than90%.
