High-speed Railway Signal Simulation Training System

In recent years,with the development of Chinese railway,high-speed railway network structure has been optimized,the proportion of the application of high speed railway signal system equipments is also increasing,and the high level personnel demand for railway equipment application and maintenance has become a significant problem that restricts the development of railway industry.The skillful use and the rapid handling faults of Centralized Traffic Control System(CTC)can improve the efficiency of traffic dispatching,reduce the workload of field workers,and ensure the safety of transportation.The System's safe and stable operation is closely related to the technical level of field workers and maintenance personnel.The using equipments of CTC are running all the day that cause fewer opportunities for students to practice learning.To solve this problem,the development of a set of demonstration training and test function simulation training system which both on-site training and teaching with simple operation condition and highly similar with real equipments has important practical significance and practical value.Firstly,this thesis briefly introduces the structure and function of high-speed signal system.According to the training needs of users,through the analysis of the principle and the whole structure of CTC system,combined with on-site survey feedback and shortcomings of the current CTC system training,through the detailed analysis of simulation and training needs of CTC station simulation training system,the functional requirements of the train station simulation training subsystem of CTC are clarified.Secondly,the CTCS-2 and CTCS-0 level standard passenger station and the interval relay station and the no distribution station are selected to combine the simulation station,and the overall design and implementation plan of the CTC station simulation training subsystem are put forward.According to the functional architecture of CTC station simulation training subsystem design,the system level and function modules are divided,and detailed analysis and design of interface display,data processing,data communication and training management are accomplished,the realization of some functions of the simulation process have been described in detail.Finally,Microsoft Visual Studio 2005 is selected as the CTC station simulation training subsystem development platform,the software development of computer simulation technology and object-oriented technology is use to actualize the subsystem.Based on the software simulation function realization of the selected stations,the basic theory of training,practical training and online examination management etc.function are realized.CTC station simulation training subsystem can further improves trainees' participation in training through text display,voice broadcast,fault case reappearance and stepwise guided demonstration training.Moreover,teachers can formulate training programs according to their needs,and carry out the introduction of training content and examination question bank.At present,the high-speed signal simulation and training system has been installed and debugged in the comprehensive laboratory of Lanzhou Jiaotong University high-speed rail signal system.The software has reserved CTCS-3 level interface to facilitate the later software upgrade access.
