Modeling And Verification Of Simulation Test Manager Of Train Control System Based On O-MaSE

The simulation testing technology of train control system is a important aspect to the development of technology and security of China's railway, especially the CTCS-3level train control system.In this paper, to the issue on how to improve and enhance the methods and quality of the Simulation Test Bench of CTCS-3level train control system, according to the theoretical background of Multi-agent system, using the theory as the core of the modeling method of the O-MaSE, the overall structure of the Simulation Test Bench is described and constructed. Given an example of the Simulation Test Manager as the core of the Bench, a distributed architecture mode of the Simulation Test Manager based on O-MaSE is proposed.The use of modeling tool of O-MaSE, the Agent Tool, to analyze needs of the Bench, divided the overall goal of the CTCS-3level Simulation Test Bench into several sub-goals and associated and mapped them, which reduces the overall complexity of system. At the same time, the Bench is organizational and sub-tasks corresponding to the goals are distributed, the organization's internal structure features are formally presented, the role models of corresponding tasks are set completely, Agents corresponding to tasks are assembled, then the structure analysis of Agents is transformed to the distributed deployment. Completed the design idea of models that agents play roles-roles maintain capabilities-capabilities provide services-services complete tasks-tasks achieve goals.Finally, by simulation testing the scene of train real-time operation of the CTCS-3level Test Sequences, the rationality of distributed architecture of the Simulation Test Manager is verified, the simulation reliability and quality and expansibility of the Simulative Test Bench of train control system combined with the O-MaSE theory are improved.
