提出一种基于因特网的远程检定方案,并利用虚拟仪器开发工具语言LabVIEW具体构建了一个以标准源远程检定数字多用表的系统。该系统在实现自动检定的基础上,允许客户远程监控检定过程并实时查看检定结果;并针对新需求,增加了计算检定数据测量不确定度的功能。
A remote verification scheme based on the Internet was proposed and a system for remotely verifying the DMM with a standard source was constructed by using the virtual instrument development tool language LabVIEW. On the basis of automatic verification, the system allows customers to remotely monitor and verify the verification process and view the verification results in real time. In addition, the system adds the function of calculating the uncertainty of measurement data verification for new requirements.
