一氧化碳气体检测仪的算法设计

摘要

Based on the principle of infrared spectrum absorption, the detection of the carbon monoxide concentration is researched.in order to improve the equipment detetion accuracy without increasing cost, two-dimensional Lagrange interpolation algorithm is adopted to interpolate the measured alpha table.Experiments show that the error caused by Lagrange interpolation algorithm is within the allowable range of equipment error, and under the conditon of same accuracy, this algorithm requires less sampling points, which reduces the equipment cost.%基于红外光谱吸收原理,对一氧化碳的浓度检测进行研究.为了在不提高成本的条件下提高设备测量精度,采用二维拉格朗日插值算法对测量alpha表进行插值.实验表明,运用拉格朗日算法进行插值造成的误差在设备误差允许范围内.该方法在同样精度条件下,需要更少的采样点数,从而降低了设备成本.
