虚拟基准、虚拟量仪、虚拟仪器和误差分离技术

VD,VG,VI & EST

深入阐述了虚拟仪器 (VI)的概念、组成、特征及其发展方向 ,分别论述了基于 VI的虚拟量规 (VG)和虚拟测量 (VM)的各自内涵 ,以及采用虚拟基准 (VD)的巨大优越性。指出虚拟基准是实施 VG和 VM的技术关键 ,误差分离技术 (EST)是虚拟基准 (VD)的理论基础之一。最后指出 ,VI,VD,VM和 EST有效集成才能实现真正意义上的几何量虚拟测试仪器系统。

In the Paper,the conception,construction,important features and development direction of Virtual Instrument(VI),and the great superiority and bright prospect of using Virtual Datum (VD) are represented.The connotation of Virtual Gauge (VG) and Virtual Measurement (VM) Based on VI is given.It is pointed out that Virtual Datum is one of the key technologies of carrying out VG and VM,the Error Separation Technique (EST) is the theoretical basis of Virtual Datum,and only by the effective integration of VI,VD,VM and EST can the virtual instrument system for measuring geometric quantities be realized in a real sense.
