The Design And Visualization Of CTCS-2 Operational Scenarios

As China continues to expand the operation scale of high-speed train, the requirements of professional knowledge and skills are also constantly improving for operation and maintenance person. Better to learn the relevant knowledge becomes necessary. The process of train operation is divided into several links by operational scenarios. And it describes the work process and interaction information between devices in each link of the train control system. It’s conductive to understand the complex system working principle and control. As for the CTCS-2 train control system doesn’t have any relevant specifications on operating scenarios, it brings some difficulties for training and teaching. Therefore, to design CTCS-2 train control system related operational scenarios and visualize it becomes more meaningful.UML language is a graphical description tool, it can be a good description of the scene processes and interactions between subsystems; Combined with the UML language, domain-driven design approach can be a good method to analyze the model of train control system. The train control system in the domain model is the business logic to the virtual computer mapping. The created domain model running through the entire development process, can accurately guide the developers at all levels of architecture to develop the platform, and reproduce real operational scenarios.Based on this, the main contents of the paper are as follows:Firstly, combined with a variety of cases encountered in actual operation of CTCS-2 train control system, designing five main operational scenarios of CTCS-2.And for each operational scenarios design specific cases. At last, extract the term, interactive subsystems and interactive process of the scene and describe it standardized.Then based on these scenes, design visualization platform. Taking into account of the characteristics of the visualization platform, using domain-driven design method to design the core part of the platform architecture. Including the train control center, interlock, feult trigger module business of train control system Then build the corresponding business domain model by UML technology. Domain-driven design ideas can not only integrate experts into the devetopment team of the field, platform can express more accurate of the knowledge, but can be transferred to focus on business bgic rather than technology. The architecture of platform is clear, devetopment tasks assigned to developers are more clear and reasonable.Then follow the requirements of do ma in-driven design ideas, begin to realize the platform. To describe the technology implementation of each layer. In view of the existing technical problems, put forward the solutionFinally, based on GuanHui intercity line data of CTCS-2 train control system, to display the main operational scenarios of CTCS-2 train control system designed before. And it was used in WuHan training center.
