Design of data access services for common information platform
Bai Richang · Dianli zidonghua shebei · 2010
The status quo of common information platform construction in dispatch center is considered synthetically and its data access service architecture is presented,which is composed of the adapter layer and the data service layer.The models of different types,such as the models stored in the heterogeneous relational databases,XML models,the models accessible via CIS interface,are integrated into the modeling environment of communal information platform at the adapter layer,which carries out the semantic transformation.Different CIM versions are compatible.The data service layer provides the CIS services conforming to semantic standards and IEC61970 and the message services conforming to IEC61968.The design concept,configuration and features of the components of adapter layer,such as universal database access,XML file access,CIS interface access and semantic transformation,are discussed in detail.The system with the proposed service architecture has excellent operational effect.
