逆反射测量系统计量检定技术

Metrological Technology of Retroreflection Measurement System

针对目前交通运输行业缺少逆反射计量标准,逆反射计量数据的准确性、有效性和统一性无法得到保证的情况,以逆反射测量系统的工作原理和数学模型的研究为基础,制定检定技术方案,通过进行重复性试验、稳定性试验、不确定度评定和结果验证等技术建立起逆反射测量标准装置,然后通过逆反射测量标准装置→逆反射标准物质→逆反射测量仪的路径进行量值传递,从而建立起逆反射量值溯源传递链,实现了逆反射性能的量值统一和计量准确,填补了国家计量体系与交通计量体系在逆反射领域的空白。

At present, there is a lack of metrological standard of retroreflection in transportation industry. Accuracy, validity and unity of metrological data of retroreflection cannot be guaranteed. On the basis of working principle and mathematical model of retroreflection measurement system, metrological plan was worked out. By carrying out repeatability experiment, stability experiment, evaluation of uncertainty and verification of result, standard retroreflection measuring equipment was fabricated. Through the route of retroreflection standard equipment--retroreflection standard substance--retroreflectometer, the metrological chain was established, and value unity and accurate metering can be realized nationally. This work filled the blank of domestic metrological system and transport metrology in retroreflective field.
