网络化测量仪器溯源检定方法初探

摘要

在梳理、总结网络化测量仪器特点基础上,根据上位机在网络化测量仪器中作用的差别,将其分为Ⅰ类网络化测量仪器和Ⅱ类网络化测量仪器两种类型;并在梳理网络化测量仪器溯源检定方法研究现状,并借鉴传统测量仪器和虚拟仪器溯源检定方法基础上,提出对Ⅰ类网络化测量仪器,可采用实验室检定、在线检定和离线检定三种方法来实现对其测量准确度等性能的溯源检定;而对Ⅱ类网络化测量仪器,则可采用在线检定和离线检定两种方法.最后,以网络化电能计量装置为例,说明了网络化测量仪器溯源检定的实施方法.%After summarizing the features of networked measurement instruments specifically, we devide them into classⅠnetworked measurement instrument and classⅡnetworked measurement instrument based on the different usage of host computer in networked measurement instrument. This paper proposes that we can adopt methods like laboratory calibration, online calibration or offline calibration to calibrate classⅠnetworked measurement instrument, and adopt methods like online calibration or offline calibration to calibrate classⅡnetworked measurement instrument based on summarizing the study achievements of traceability and calibration methods of networked measurement instrument and referring to the traceability and calibration methods of the traditional instrument and virtual instrument. Finally, net-worked electric energy metering system is used to explain the implement of traceability and calibration of the networked measurement instrument.
