摘　　要：天牛是危害林木的主要害虫之一,林木在受到天牛侵害时会产生挥发性物质。文中利用电化学气敏传感器构造传感器阵列,进行了相应的电路设计、抽气装置设计以及Labview软件设计,构造了一个较为完善的电子鼻动态系统。此系统可以识别受天牛侵害林木的气味信息特征,从而准确快速地检测天牛的存在。测试实验结果表明,设计的电子鼻系统对是否有天牛的辨识率可达90%。Longicorn is one of the main pests of forest,forest in the damaged infringed will produce volatile substances.In this paper,an array of sensors is constructed by using electrochemical gas sensors.And the circuit is designed accordingly,pumping device design and Labview software design,construct a perfect dynamic electronic nose system.This system can be identified by smell information characteristics of forest beetle infringement,so as to accurately detect the presence of longicorn fast.The experimental results show that the electronic nose system design is the identification rate of90% beetles on whether.
