虚拟仪器系统动态重构管理技术研究

Research on the dynamic reconfiguration management technology of virtual instrumentation system

针对目前虚拟仪器平台的功能由仪器厂商来定义而导致测量仪器功能单一和灵活性差的问题,在基于现场可编程虚拟仪器内核和XVIML的基础上提出了的动态可重构虚拟仪器的总体架构,开发了动态重构管理平台管理构件的装配、连接和一致性约束,完成了虚拟仪器系统的开发环境和运行环境的统一,用户可以快速自定义测量系统的功能。

Based on field programming virtual instrumentation（FPVI） and XVIML（XML-Based Virtual Instrument Markup Language） model, the architecture of dynamic reconfigurable virtual instrumentation is proposed to solve the problem of single function and bad flexibility of tradition virtual instrumentation. Dynamic reconfiguration management system has been realized to manage assembly,connection and consistency constraints of component. In this way, the development and running environment of measurement system has been unified to realize fast reconfiguration of measurement system.
