多气体传感器信号样条回归信息处理

Signal Processing of Multi-gas Sensors Based on Spline Regression

用样条回归分析方法于电子鼻系统中多气体传感器信号信息处理.针对牛肉样本建立了牛肉新鲜度样条回归模型,并对该模型进行了回归分析.研究结果表明,所提出的方法适用于电子鼻系统对牛肉新鲜度检测中的信息处理.

Regression analysis is a mathematic tool to study the relationship between a variable and other relevant variables. Spline regression analysis is used in the multi-gas sensor signal information for an electronic nose system. This paper presents beef freshness spline regression model according to beef sample, and carries out regression analysis for this model. The result shows it is proper to identify beef freshness in beef sample with an electronic nose system.
