Embodiment Construction

[0026] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] The invention adopts the public information model CIM as the standard data model for inter-system data exchange, parses the information data from the private data model XML file of the application system, and converts it into a model data file conforming to the CIM semantics and grammatical structure according to the mapping rules. The present invention is based on a kind of mapping system adopted here, its structural diagram is as follows figure 1 As shown, it mainly includes a file parsing module, a mapping unit and a data model storage unit, wherein the file parsing module is used to extract file data information; the mapping unit allows users to configure model mapping rules according to different applications of their own systems and implement the system through mapping rules. Conversion between private data ...

Abstract

The invention relates to a mapping method and a system of a system data model to a CIM. The method includes configuring model mapping rules, receiving model files from corresponding application systems, and verifying and analyzing the model files to obtain information data of the application systems; judging whether model mapping rule files are loaded by the mapping system, if the files are not loaded, building a mapping rule between a private data model and the CIM through a configuration tool for model mapping rules; according to the mapping rule, private information data of the application systems are converted into CIM data and are stored in a CIM library through a mapping unit; and finally, obtaining all information data by browsing the list structure of a whole CIM data library, organizing information data according to resource description framework (RDF) specifications, exporting standard CIM / extensible markup language (XML) files for being called by other application services and components.

Description

technical field [0001] The invention relates to the field of power system automation, in particular to a mapping method and system from a system data model to a CIM model. Background technique [0002] With the rapid development and popularization of computer technology and communication technology, the informatization of the power industry is developing rapidly, and the interaction and sharing of data between a large number of application systems in power companies is becoming more and more frequent. However, when developing and designing application systems, the power system model Descriptions vary, and how a power system is described usually depends on the application. These application systems are often designed and developed by different manufacturers. Based on different operating systems and data platforms, the data and information formats are incompatible with each other. The resulting "information island" phenomenon makes it impossible for enterprise resources to be ...
