数字式多功能标准检定装置自动校验系统开发与应用

针对交直流仪表检验装置和数字多用表人工检定效率低的问题,以Delphi 7和Visual Studio作为开发工具,开发数字式多功能标准检定装置自动校验系统。系统分为数据通信、软件处理和系统数据库三个部分,实现了基本误差、输出稳定度、测量重复性、三相不对称度、波形失真度全自动校验,并增加了源输出稳定时间的自动设置和不确定度自动评定功能,具有测试准确度高、检测效率高、操作简单等优点,有很强的工程实用性。

Development and Application of Automatic Calibration System for Digital Multifunction Standard Verification Equipment

To the low efficiency problem of instrument calibration equipment and digital multimeter verification by manpower,an automatic calibration system for digital multifunction standard verification equipment is developed based on Delphi 7 and Visual Studio.The system is consist of data communication,software process and database,which can not only realize the automatic calibration of basic error,output stability,measurement repeatability,three-phase unbalance factor and waveform distortion,but also add functions like automatic setting of source output stable time and automatic assessment of uncertainty.The system has advantages of high measurement accuracy,high calibration efficiency,easy operation and thus has stronger engineer applicability.
