本文在梳理城市轨道交通产业计量需求的基础上,分析了产业计量服务城市轨道交通产业(以下简称“城轨产业”)的应用路径。一、城轨产业的计量需求分析城轨产业的主要计量需求如图1所示。1.量传溯源的需求在现有计量技术条件下,城轨大部分通用计量设备都能得到有效量值溯源,但部分新型专用计量设备,如地铁的第三轨接触网测量仪等,并不能直接通过现有的计量标准进行量值溯源,需计量技术人员开发专用的计量标准和建立新
On the basis of combing the metrological requirements of urban rail transit industry, this paper analyzes the application path of industrial metrology service urban rail transit industry (hereinafter referred to as “urban rail industry”). First, the metrology needs of the urban rail industry The main metrological needs of the urban rail industry as shown in Figure 1. 1. The demand of mass traceability Under the existing measurement technology, most of the common metrology equipment of urban railways can be traced back to effective quantities, but some new type of special measuring equipment, such as the third rail contact net measuring instrument of the subway, etc. Not directly through the existing measurement standards for traceability, the need to measure the technical staff to develop specific measurement standards and the establishment of new
