Abstract


CTCS-3 Train Control System is a \Do a good job of CTCS-3 train control system of technological innovation, has far-reaching implications of China's railway train control system technology development and raise the level of communication signal equipment and technology. CTCS-3 Train Control System technology innovation will rely on the Wuhan-Guangzhou, Zhengzhou-Xi'an, Guangzhou-Shenzhen-Hong Kong Passenger Line construction projects, through the introduction of the key technologies of the train control system, the joint design, joint development, joint research, and combined with the successful application of the CTCS- two technologies, build CTCS-3 train control system in line with China's national conditions and road situation, with independent intellectual property rights. RBC (Radio Block Center, hereinafter referred to as RBC) is one of the core equipment of CTCS-3 Train Control System, the first before use to make a complete functional testing is essential. In this thesis, RBC test. First, a detailed analysis of the functional requirements of RBC cited seven functions of the power-on self-test, security, link management, train information management, driving license management, RBC handover management, vehicle mode management, database management system, and a brief description of the RBC with the interface between the various devices, simulation test platform and complete feature data flow test reaction RBC test methods; Secondly, RBC workflow object, its model to generate use case diagram, state diagram , activity diagrams, and extract features of modeling diagrams, design test cases; then introduces the principles of necessity and design of the test sequence, divided and described the scene to participate in all RBC scenario-based design ideas design and generate test sequences according to the basic scenario and the alternative scene in series; Finally, using TTworkbench tool designed and implemented based on TTCN-3 the RBC test the system, to simulate the RBC simulation testing support environment to achieve a The function of the control and management of the testing process, a detailed description of the process of the realization of the test system, simulation experiments and analysis of the experimental results. The innovative point of this paper is to draw on the methods of communication protocol testing, the use of black-box testing of the new standardized TTCN-3 language test train control equipment RBC. Simulation analysis showed that the design proposed in this paper is feasible.
