摘要

根据相关国标设计了一种便携式逆反射系数测试仪，用于测量交通标志、机动车车身标识和高能见度警示服等材料的逆反射系数。分析、比较了逆反射系数测量原理，基于相对测量法研制了逆反射系数测试仪。该逆反射系数测试仪以白色发散光作为光源，可以在近距离下模拟逆反射标识的实际工作状况，完成逆反射系数的测量。介绍了逆反射系数测试仪中光学系统、光电转换电路和STM32F103C8T6单片机控制系统的设计方法，建立了基于最小行车安全距离的逆反射系数测试角度的选择模型，完成了逆反射系数测试仪不确定度的评估。最后，利用研制的便携式逆反射系数测试仪进行了实验测试。结果显示：在测试条件为（0.1~199.9）cd·lx

-1

·m

-2

时，其示值误差的最大值为4.40%；当测试条件大于199.9 cd·lx

-1

·m

-2

时，示值误差的最大值为1.31%，符合GB 26377-2010对示值误差的要求。设计的逆反射系数测试仪具有小型化和智能化的优点，对现场检测交通安全标识、机动车车身标识等具有实际意义。

Abstract

A portable retroreflection coefficient detector was designed according to relevant national standards to measure the retroreflection coefficients of the traffic signs

vehicle body markings and high visibility warning clothes. The measuring principles of retroreflection coefficients were analyzed and compared

and the retroreflection coefficient detector was developed based on the relative measurement method. White reflecting light was used as the divergent light source of the retroreflection coefficient detector

and it could simulate the actual working condition of retroreflection objectives in a short distance and to complete the measurement of the retroreflection coefficients. The designs of optical system

photoelectric conversion circuit and STM32F103C8T6 single-chip control system in the detector were introduced. A selection model for the test angles of retroreflection coefficients was established based on minimum safety driving distance

and the uncertainty of the retroreflection coefficient detector was evaluated. Finally

a test experiment was performed by using the portable retroreflection coefficient detector. The experiment results show that the maximum value of the indication error is 4.40% in the test range of (0.1-199.9) cd·lx

-1

·m

-2

and that is 1.31% in the test range greater than 199.9 cd·lx

-1

·m

-2

which meets the requirement of GB 26377-2010 for indication errors. The portable retroreflection coefficient detector has advantages of miniaturization and intellectualization and has practical significance to detect the traffic safety signs and vehicle body signs.
