摘　　要：为了在零网络编程的情况下实现虚拟仪器的远程测控,通过对虚拟仪器技术和网络技术的研究,提出了一种采用B/S结构并基于Applet与Servlet的虚拟仪器远程测控系统模型。运用UML"4+1"视图模型进行了系统用例视图、逻辑视图、进程视图以及部署视图的设计,并在设计中详细讨论了系统的网络交互和数据传递。虚拟仪器远程测控系统具有零网络编程和零虚拟仪器软件修改的特点。应用实例表明该系统模型可以实现实时远程测控。On the basis of research of the technology of virtual instrument and network, a B/S structure model of the remote measurement and control system of virtual instrument based on Applet and Servlet （AS-VIRMCS） was presented to implement remote measurement and control without network programming. Further, the UML＂4＋1＂ view model was used to design a set of system diagrams such as use-case diagram, logical diagram, concurrency diagram and deployment diagram, which discussed network interaction and information transmission in detail. The AS-VIRMCS system is characterized by no network programming and no reworking in the software of virtual instrument. Finally, it was proved that the system model can do well in remote measurement and control by an application.
