非接触式汽车速度计对测速仪现场检定结果的影响分析

随着经济发展,道路等级越来越高,汽车超速问题也日益凸显。机动车测速仪是交警部门用于执法的工作计量器具,其量值需经过溯源才能保障准确可靠。测速仪现场检定其中一种方法是采用非接触式汽车速度计作为标准装置,其在现场主要受到安装、车身抖动等环境因素的影响。本文介绍了机动车现场测速误差检定时各种因素引入的测量不确定度分量的计算。

With the economic development,the road ranks are getting higher and higher,and the problem of speeding cars is becoming more and more prominent.Motor vehicle speedometer is a working measuring instrument used by traff ic police departments for law enforcement,and its quantity must be traced back to ensure its accuracy and reliability.One of the methods of spot test of speedometer is the use of non-contact vehicle speedometer as standard device,which is mainly affected by environmental factors such as installation and body jitter.This paper introduces the calculation of the uncertainty component of measurement introduced by various factors during the spot speed measurement error verif ication of motor vehicles.
