The higher demands for detecting systems are proposed in the functional and user - friendly interface to meet a virtual instrument in the present. Combining with configuration and control of software bus technology, based on the software bus configuration of the virtual instrument control system, the design method is proposed in the traditional technology of virtual instrument, different functions of the virtual instrument system are generated to achieve dynamic test of online, 3D virtual control is built by using of GDI ＋ and by loading different software bus control. In ensuring the safe operation of the system, the functionality in the test configuration of field devices and the system scalability are real：zeal.针对当前虚拟仪器对测量仪器系统在功能和人性化操作界面上所提出的要求，以传统虚拟仪器技术为基础，结合软总线控件技术和组态技术，提出了一种基于软总线控件组态化的虚拟仪器系统设计方法，同时利用GDI＋构建了3D虚拟控件库．通过加载不同的软总线控件进行简单的配置，既可生成典型信号分析系统，又可生成具有不同功能的其他虚拟仪器系统，进而完成在线动态测试．在保证系统安全运行的前提下，实现测试现场设备的功能组态化，增强了系统的可扩展性．
