摘要
文中介绍了气体传感器特性曲线拟合的最新研究。由于传统的模型及方法已不能满足现代科学对数据精度与曲线匹配性高的要求,需要采取一种有效的、低误差的改进校准方案。文中采用虚拟仪器技术与最小二乘法大幅度提高了气体传感器的测量精度。
The latest research into the gas sensor＇s calibration models and methods is introduced. Since traditional models and methods fail to meet the data precise requirement in the modern science, a scheme with better efficiency and lower error for improving calibration is needed. In this paper, the technique of the virtual instrument and the method of leastsquare is proposed, which can largely improve the measurement precision of the gas sensors.
