摘要: 针对目前图编程设计软件对界面的形式化描述不规范而导致的数据交互能力不强的问题,提出了一种基于XML的嵌入式异构域图编程数据标准描述方法。以IEC61131-3和IEC61499标准为基础,将图元表示为表现型和执行型部分,抽象出图编程数据标准描述模型及图元构件关系。通过对其形式化定义与描述,为图编程数据描述文件的交互提供转换基础,提高图编程数据的交互能力。可行性和有效性得到了实验验证。

Abstract: To deal with the problems of data exchange among embedded heterogeneous domains caused by non-standard description of user interface, a standard description approach based on XML is proposed. Taking IEC61131-3 and IEC61499 standard as basis, graphical controls are expressed as visible part and executable part. A standard graphical data description model and the relationship among graphical controls are abstracted. The formal definition and description of the model provide the basis for conversion of graphical programming data and improve the ability of data interaction. The effectiveness and feasibility of description approach are verified by the experiment.
