摘要
以LabVIEW9.0为测试平台,利用PCI—1710HG数据采集卡、传感器阵列设计构成智能电子鼻系统。虚拟仪器开发平台LabVIEW用于实时监测、显示采集曲线和数据、结合改进后的BP神经网络进行分析以得到不同体积分数的气体。对系统进行了测试,采用不同阻值的精密电阻器替代传感器进行测试,测试系统的精度和稳定度。
An intelligent electronic nose system based on LabVIEW 9.0,PCI—1710HG data acquisition card and sensor array is designed.Virtual instrument development platform LabVIEW is used for real-time monitoring and displaying of collection curve and data.Combined with the improved BP neural network to analyze and get the volume fraction of different gases.Test on the system is carried out and sensor array is replaced by different value of precise resistance to test the precision and stability of the system.
