摘　　要：阐述了虚拟仪器技术发展的现状,结合USB系统现有监控手段的局限性提出构建基于VI技术的监控系统;分析了虚拟仪器监控系统网络模式;进行了USB系统监控设计;根据USB系统实际情况,利用LabVIEW软件对系统监控进行了模拟仿真。仿真结果表明,基于虚拟仪器技术的测控系统监控设计简洁高效,准确反映了实时信号的特征,大大拓展了系统监控台的功能,集成度高,能有效减少硬件设备的使用,节省大量装备经费,完全符合测控系统发展的需要。The development status of the virtual instrument technology is described in this paper. In consideration with the limitations of the existing monitoring means of the USB system, a proposal of building a monitoring system based on virtual in- strument technology was made. The network model of virtual instrument monitoring system was analyzed. The monitoring design of USB system was conducted. The monitoring system was simulated with LabVIEW software according to the actual situation of the USB system. The simulation results show that monitoring system based on virtual instrument technology is simple and effi- cient, which can accurately reflect the real-time characteristics of the signal, and greatly expand the functionality of the system monitoring station, and its high integration is effective in reducing the application of hardwares, and saving a lot of equipment funding. All of the above fully complies with the development demand of the measurement and control system.
