摘　　要：介绍了虚拟仪器的原理和系统构成 ;提出了利用VC + +高级编程软件组建基于PC -DAQ的虚拟仪器的关键技术 ,并创建了可视化的虚拟仪器面板 ;借助其先进的DLL和ActiveX技术实现了软件的模块化设计 ,提高了软件的可维护性、扩展性和开发效率。在此基础上 ,成功地开发了基于PC -DAQ面向精密测量的虚拟仪器 ,实现了检测的可视化、智能化。The principle and system structure of the virtual instrument are introduced. Making use of the visual C++ language, the key technologies of building virtual instrument are put forward based on the PC DAQ, and the interface of visual virtual instrument is developed. The software module is implemented by mean of the DLL and ActiveX in the Visual C++ language, so the maintainability, expansibility and efficiency of the software are remarkably improved. The virtual instrument of precision testing oriented has been developed, and the visualization, intelligent and automation in the measurement are achieved.
