摘要
由中国计量科学研究院作为主导实验室的全国非接触式汽车速度计比对于2018年完成。作为机动车测速计量领域的首个固定地点的现场比对,参比实验室29家,其中27家为已建标的省级计量技术机构,全部比对结果为满意。介绍了比对的基本情况、技术方案,研究了比对方法和不确定度来源,提出了测速计量现场比对的特殊性,分析了比对结果。
The national comparison of non-contact speed meters was finished in 2018. The pilot lab was National Institute of Metrology,China. As the first comparison of fixed measurement spot type in on-site speed measuring metrology,29 participating laboratories were involved,among which 27 were provincial level metrological institutes. All participating laboratories got satisfied results. The technical background and comparison program were introduced,the comparison method and uncertainty components were studied,the metrological particularities of speed measurement were proposed,and the comparison results were analyzed.
