语法制导生成的虚拟仪器开发平台

Virtual Instrument Development Environment Generated by Syntax-directed Method

如何以一种与特殊的图形用户接口无关的形式一致地描述数据流可视化编程语言及其开发平台,成为虚拟仪器开发平台自动生成的主要问题。该文以自主研制的开发平台LabScene为例,形式化地描述其中最主要的3个部分:编辑,运行,调试,把这些形式化的描述翻译成C#语言,实现自动生成,为以非数据流为核心的虚拟仪器开发平台的自动生成提供参考依据。

The key problem of auto-generation of virtual instrument development environment is how to congruously describe DataFlow Visual Programming Language（DFVPL）and its environment in a way independent of a particular GUI implementation. With the example of virtual instrument development environment, LabScene formally describes three most important parts： edition, execution and debugging, and translates them into C# language to realize auto-generation of virtual instrument development environment. The method is the reference of auto-generation of virtual instrument development environment which is not build on dataflow.
