Research On The Comprehensive Dispatching System Of High-Speed Railway Interoperability Technique

High-speed Railway is a comprehensive dispatching system consisting of a large number of specialized subsystems and complex large system, which involves the transport organizations,locomotives and rolling stock, communication signal, power supply, security, monitoring, maintenance and rescue and other disciplines. Information on how these aspects together, unified planning and design, constitute a reasonable structure, complete functions, technically feasible in formation systems must use to a variety of cuttingedge technology, interoperability, technology is one of the key technologies of which this paper is to In view of this key technology research.In this paper, a detailed analysis of high-speed railway scheduling system is characterized by an integrated function of various subsystems configuration, the introduction of SOA architecture design method is proposed based on the exchange of information-sharing platform for the general framework of an integrated scheduling system, and its key techniques introduction; followed by the application subsystem interconnect than election to determine an integrated scheduling system interconnect structure with hierarchical and distributed. Then, this paper, an integrated high-speed rail dispatching system features an integrated dispatch system for the existence of heterogeneous platforms interoperability issues raised by real-time CORBA technology, interoperable middleware layer model, each application subsystem interoperability and integrated scheduling model hierarchical model of the system interoperability; and finally discussed based on real-time CORBA platform, interoperable middleware layers of the relevant implementation technology, using multithreaded and parallel processing of double-buffering techniques, focused on the service interoperability layer interface and the management services algorithmic process. This study results for future high-speed railway construction of an integrated dispatch system and a seri es of key technical issues must also a good inspiration.
