| 摘 要： | 为了解决现有的单一AOV网和树模型不能描述G语言语法的双重关系,即基于数据流的数据流向关系和程序控制的容器控制关系,在层图和其子集兄弟图定义的基础上,提出兄弟AOV网的概念,用它来构造G语言的基本结构模型,并结合兄弟AOV网的排序和元素的关系传递规则实现了G语言的运行模型。在自主研制的虚拟仪器开发平台LabScene中应用了此模型,使开发出的虚拟仪器可以按照用户设计的控制方式结合数据流向来解析运行。

| Abstract: | In order to resolve the problem that the single AOV network and the existing tree model cannot express the dual relations of the syntax of the graphic language,i.e.,the data directional relation based on the dataflow and the vessel control relation of the program control,a concept of brother AOV network was suggested based on the definitions of lager graph and its subset, brother graph,to form a basic structural model of the graphic language,and its operation model was realized in combination with the sorting and the node relation transmission rules of the AOV network.This model has been applied to the self-developed virtual instrument developing platform called LabScene and makes the virtual instrument run by parsing method according to the control pattern and dataflow designed by the user. |
