基于蒙特卡洛法的计价器检定不确定度评定

Uncertainty evaluation of taximeter verification based on Monte Carlo method

采用蒙特卡洛法评定出租汽车计价器检定测量不确定度,讨论GUM法与MCM法评定过程中的差异。基于Python开源库开发了面向计价器计量工作的MCM法评定计价器不确定度软件,提供直观详细的输出量概率密度分布图以及报告结果,并验证了GUM法的结果。研究表明,GUM法与MCM法都适用于计价器检定测量不确定度评定。

Monte Carlo method is used to evaluate the measurement uncertainty of taximeter verification,and the differences in the evaluation process between GUM method and MCM method are discussed.Based on the python open source library,the software for evaluating the uncertainty of the taximeter by the MCM method is developed for the measurement work of the taximeter,which provides intuitive and detailed output probability density distribution graphs and report results,and verifies the results of the GUM method.The results show that both the GUM method and the MCM method are suitable for the evaluation of the measurement uncertainty of the taximeter verification.
