在分析无线闭塞中心(RBC)运营场景的基础上,研究利用Rhapsody建模工具建立RBC运营场景模型,并以RBC与外部系统之间的关系、列车状态和RBC移交列车为例,描述整个RBC运营场景的建模过程。用例图从最高层抽象出构成RBC系统的对象以及各个对象之间的相互关系,用状态图建立RBC各个场景的状态模型,用顺序图描述各个系统的信息交互顺序;利用Rhapsody中提供的动态模型执行功能,查找无线闭塞中心系统设计上的错误和缺陷,为完善RBC设计和系统开发提供依据。
Based on the analysis of RBC operating scenarios, this paper studies the use of Rhapsody modeling tools to establish the RBC operating scenario model and describes the relationship between RBC and external systems, train status and RBC hand-over trains as an example to describe the RBC operation Scene modeling process. The use case diagram abstracts the objects that constitute the RBC system and the interrelationships between the objects from the top. The state diagram of RBC scenes is established by using the state diagram, and the sequence of information exchange of each system is described by the sequence diagram. By using the dynamic model provided by Rhapsody Executive function, find the wireless center system design errors and defects, to improve RBC design and system development to provide the basis.
