摘要
综合考虑调度(监控)中心建设公共信息平台的实际现状,提出了公共信息平台的数据访问服务体系架构,该架构分适配器层和数据服务层2层设计。其中,适配器层实现将存储在异构关系数据库中的模型、XML模型以及可通过CIS接口访问的模型等多种格式的模型集成到公共信息平台的建模环境中,并对这些模型进行语义转换,同时兼容不同时期的CIM版本;数据服务层完成对外提供具有标准语义的、遵循IEC61970的CIS服务以及遵循IEC61968的消息服务。对适配器层中的通用数据库访问组件、XML文件访问组件、CIS接口访问组件以及语义转换组件等的设计思想、结构和特点进行了详细阐述。该服务架构应用于实际系统取得了良好的运行效果。
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.
