【摘要】：配电网统一信息模型是实现智能配电网信息交互和应用集成的基础,但模型版本更迭和私有扩展造成的信息模型异构会导致语义冲突,导致互操作的失败。为解决这些问题,文章实现了基于本体映射分析的公共信息模型在不同版本间的转换映射方法。首先提出了基于本体的信息模型转换映射算法,通过SAX解析确定CIM/RDF中待转换的元素,设计深度搜索算法得出待转换类和属性的映射规则库。在此基础上,使用扩展样式表转换语言(XSL transformation,XSLT)技术实现了CIM/RDF等实例数据向不同版本模型定义的数据格式的映射,完成了异构域XML的自动转换,并以变化较大的变压器模型作为算例说明转换过程和方法。文中成果为异构模型交互提供了模型映射基础,有助于信息交换总线上实现异构模型的辨识与交互。
[Abstract]:The unified information model of distribution network is the foundation of intelligent distribution network information interaction and application integration, but the heterogeneous information model caused by model version change and private extension will lead to semantic conflict and failure of interoperation. In order to solve these problems, this paper implements the transformation mapping method between different versions of common information model based on ontology mapping analysis. Firstly, an ontology based mapping algorithm for information model transformation is proposed. The elements to be transformed in CIM/RDF are determined by SAX analysis, and the mapping rules of classes and attributes are obtained by designing a depth search algorithm. On this basis, the extended stylesheet transformation language (XSL transformation,XSLT) is used to realize the mapping of instance data such as CIM/RDF to the data format defined by different version models, and the automatic transformation of heterogeneous domain XML is accomplished. The transformation process and method are illustrated by a transformer model with a large variation as an example. The results of this paper provide the basis of model mapping for the interaction of heterogeneous models, and are helpful to the identification and interaction of heterogeneous models on the information exchange bus.
