Research And Design Of Middleware Platform For The Comprehensive Dispatching System Of High-Speed Railway

The high-speed railway integrated dispatching system integrated the train operation dispatching, the transportation planning management, the power dispatching, the motor train unit dispatching, the comprehensive maintain system, the passenger service and so on. The key issues are how to realize transparent data sharing and the Interoperability between the subsystem. This thesis is focus on the important question to conduct the correlation research.At first, the functional requirements of Chinese high-speed railway integrated dispatching system are analyzed in detail, the integrated dispatching system's frame based on the general technical platform used Process-Oriented methodology is proposed. Then through the comparison and selection of the application subsystem's interconnection way , the layering distribution interconnection structure of integrated dispatching system is determined, and the corresponding general technical platform structural model is also given. In this foundation, with the combination of the characteristic of the high-speed railway integrated dispatching system , one method is presented to solve the interoperability question between the isomerism platform , exited in the high-speed railway integrated dispatching system, using middleware technology based on CORBA. The whole scheme of the middleware has been put forward, and the layered-interoperability model based on the CORBA principle, including the interoperability model collectivity design, management service design in service interoperability layer and communication interoperability layer design are designed. Furthermore, RTCORBA platform---TAO is selected to carry on the discussion to the correlation realization technology of Interoperability middleware, the multi-thread and the double cushion parallel processing technology are used to realize it, the interface and the arithmetic flow of management service in interoperability layer have been designed in detail . Finally , the integrated dispatching experiment system with the interoperability middleware is built for the analogy experiment with the simulation experimental project of Beijing-Shanghai high-speed railway integrated dispatching system , the test result indicate : The layered interoperability model design is feasible, the common software-bus based on the distributed middleware has been realized, has the good Interoperability and application software integration ability. The research results should have certain reference value to the research and development for Chinese high-speed railway integrated dispatching system.
