摘要：本文结合我们开发的一套用于电工仪表检定的虚拟仪器系统，讨论了虚拟仪器系统开发过程中两个主要问题：一是接口及通讯，二是人机界面及数据处理。计算机经GPIB总线采集各项测试数据，通过自行开发的测试软件，实现对仪器设备的程控及各项参数设置，并对测试数据自动处理，生成检测报告。

Abstracts: According to a virtual apparatus system for electric apparatus verification developed by ourselves, this paper discussed two problem existed in the process of designing virtual verification system. The first problem is interface and communication. The second problem is man-machine interface and data processing. The computers collect various measurement data by GPIBbus, realize program controlled and parameter setup by measurement software developed by ourselves, auto-process measure data and produce measurement report.
