Research on Correction Algorithm of Vehicle Gas Sensor Measurement Results

针对车载气体传感器测量准确度低的问题,运用前向和反向两种修正算法对其测量结果进行后修正处理,从而提高测量数据的可信度。通过车载气体传感器与固定监测点分析仪器的测量结果进行比较,验证了这两种算法,测量结果修正后,测量误差降低了50%。此外,又提出了基于这两种算法的多级修正模型,并对其进行评估,经过测试,两种算法在该模型上的测试结果基本满足需要。

In order to solve the problem that the measurement accuary of the vehile gas monitoring sensor is low.Forward and reverse modified algorithms were used to post-correct their measurement,thus improved the credibility of the measurement data.Through the comparison between the measurement results of the vehicle gas sensor and the fixed monitoring point analysis instrument,the two algorithms were verified,and the measurement error is reduced by 50%after the measurement result was corrected.In addition,a multilevel modified model based on these two algorithms was proposed and evaluated,and the test results of these two algorithms on the model satisfied the demand basically.
