Research And Implementation Of The Generation Method Of Movement Authority In Radio Block Center

The CTCS-3train control system is the important technical equipment to ensure the safe, reliable and efficient operation of high-speed train. The Radio Block Centre (RBC) is the key equipment of CTCS-3. Based on the information (i.e. track occupation status, route status, temporary speed restriction, etc.) received from the external trackside system (including station interlocking equipment, neighbor RBCs, temporary speed restriction server) and the information (position report) from on-board equipment, the RBC generates Movement Authority (MA) and sends it to the train under its control, to make the train run safely in the RBC controlled area. MA generation is the core function of RBC, which is the basis for RBC to perform the functions required under various operational scenarios. The generation of MA involves several aspects, including the track layout topology inside RBC, the correct mapping of all kinds of information on the topology and the effective train management.In this thesis, the generation method of MA is researched and implemented on the basis of RBC Simulator. Firstly, the requirement analysis for MA generation under major scenes (including the level transition, RBC/RBC hand-over, passing through neutral zone automatically, temporary speed restriction, Calling On mode, etc.) are carried out; the UML model of MA generation is established, including use case diagram, sequence diagram, collaboration diagram; the MA generation function is divided into train path management, MA calculation (creating MA, updating MA, shortening MA, etc.), and MA management (including MA type management, MA deletion, MA transmission, etc.) and other functional modules, and the class design is finished. Secondly, two schemes for MA generation, i.e. off-line MA generation and real-time MA generation are compared, and based on the latter one, the overall design and detailed design of the MA generation algorithm are completed, and the overall activity diagram and the activity diagram of the various sub-modules for the algorithm are established. Finally, on basis of the RBC Simulator, the MA module is implemented, and through the joint debugging with other subsystems in the CTCS-3integrated simulation platform, the correctness of the algorithm is verified.
