摘要：
为更准确地检测机动车超速监测系统现场测速误差,以社会车辆为目标速度源,在机动车超速监测系统的临近位置,架设更高精度的测速装置,对相同速度监测和图像采集区域内的社会车辆,进行同步测量和同步图像采集,通过对比两者的速度量值实现对超速监测系统的检定校准。该装置用于检定道路超速监测系统的速度量值线性与误差,可以测量足够多的社会车辆样本,重点选取限速点附近的速度测量值进行对比分析。装置安装简单,使用方便,可以大幅提升检定效率与操作安全性。

Abstract: In order to accurately detect the velocity error of motor vehicle speed monitoring system, a high accuracy velocity measurement device was set up next to the vehicle speed monitoring system. The device is able to carry out synchronous measurement and synchronous image acquisition on the social vehicles in the area of equal speed monitoring and image acquisition. Based on a target velocity source of social vehicles, the vehicle speed monitoring system was verified and calibrated by comparing the two velocity values between the target vehicle and measured vehicle. In order to verify the linearity and error of the measured velocity values of the monitoring system, the proposed verification device is able to measure as many samples of social vehicles as possible and comparatively analyze the measured velocity values around the limited value. The device is easy to install and convenient to use. It can significantly improve the efficiency of verification and operational safety.
