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。
The electrified railway telecontrol system is composed of the RTU of the electric traction substation, the telecontrol channel and the master station system of the power dispatch center of the Railway Administration. The data flow of the system is analyzed, and the functions of the flow chart and system realization are given. UML is adopted to design, and a publish / subscribe-based Object Request Broker (CORBA) notification service is implemented for processing high level real-time data. Described are the handling of alarm information and background server data acquisition. According to different types of data have different characteristics and the corresponding scope of application is different, proposed to be based on the needs of the application modeling. The correctness of modeling was verified by successful operation in several large real projects.
