The CTCS3 Simulation And Test Platform--Research On CTC Field Equipment Simulation Subsystem

At present, the application of traffic control system in foreigner countries is very prevalent. The development of high-speed traffic goes rapidly. With the high-speed development of Chinese railway, a kind of train control system which can ensure the safety and efficiency of train operation emerges as the times require combined Chinese situation. It's the third level of CTCS which integrates the pivotal technology of ETCS based on the second level of CTCS. Because the foreign countries refuse to convey their core technology, we must research the emulation and testing technology platform to provide assistant design, developing method, validating and testing way to CTCS-3.The paper gives a brief introduction of the architecture, subsystems' function and flow of data of the CTCS3 train control simulation and testing platform, also decentralized self-discipline and CTC are introduced. The primary research of this paper is CTC Field Equipment Simulation Subsystem in each station of the system. The aim is to emulate multi-station in one computer via IDE C++ Builder 6.0.The mission of the paper is to build the model of the station; connect to the emulating manager; configure the corresponding parameters from emulating manager, and connect to interlock and RBC by the Ethernet. The debugging with them is demanded; Besides, CTC Field Equipment Simulation Subsystem' key functions such as route search; prearrangement and sending these results to interlock are required. Besides other functions such as multi-station management and communication monitoring are realized.Started with the background, conception, function and the technology condition of dispersive and autonomic CTC, this paper has elaborated on the structure, function, flow of data and all the modules of CTC Field Equipment Simulation Subsystem in detail. Moreover, in the end, the paper has introduced the core arithmetic and technology which have been used in the design. In addition, the results of debugging in subsystem and interface modules are displayed and analyzed.At present, the CTC Field Equipment Simulation Subsystem has accomplished the debugging with interlock and emulating manager.
