电气化铁道远动数据库系统业务流程的UML建模

摘要:
电气化铁道远动系统由电力牵引变电所RTU、远动通道和铁路局电力调度中心主站端系统构成。分析了系统的数据流程,给出了流程图及系统实现的功能。运用统一建模语言(UML)进行设计,对处理高实时性一级数据采用基于发布/订阅的对象请求代理(CORBA)通知服务实现;描述了处理报警信息、后台服务器数据获取等。根据不同类型的数据有不同的特点及对应的应用范围也是不同的,提出要根据应用需要分别进行建模。通过在多个大型实际项目中的成功运行验证了建模的正确性。

Business service flow modeling with UML for electrified railway SCADA database system
Qu Zhijian  CHEN Jianyun  CHEN Qiulin
Abstract:
The electrified railway SCADA (Supervisory Control and Data Acquisition) system is composed of traction substation RTUs,communication channels and master station. The data business service flows of SCADA system are analyzed and the system functions and flow charts and provided. UML (Unified Modeling Language) is used in design and the real - time processing of the first grade dada is realized with CORBA (Common Object Request Broker Architecture) based on publication / subscription notification service. The alarm processing and server accessing are described. As different types of data have different characteristics and different application scopes,different applications should be modeled respectively. Successful applications in several projects have verified the correctness of the modeling with UML.
Key words:  electrified railway,SCADA system,UML,CORBA
