Research on distributed simulation framework of train control system based on SOA

Service Oriented Architecture (SOA) provides a new mode for the distributed computer simulation which has the characteristic of scalability, reusability and interoperability. In order to meet the needs of reusability and continuous development functions of the train control simulation system, this paper proposes a distributed simulation framework based on SOA; Meanwhile, using the hierarchical structure, the framework is divided to four levels which include simulation management level, simulation application level, simulation basic resource level and simulation middleware level to achieve scalability, reusability and interoperability. SOA and four hierarchical structure together can support for the compatibility and sustainable of train control simulation system. Finally, Chinese train control system level 3 (CTCS-3) is taken as a case, and the availability and scalability of the framework have been analyzed.
