Research On Railway Multi-work Joint Simulation Training System Based On CTC Scheduling Operation

With the rapid development of railway in China,railway transportation has become an indispensable part of social economy and daily life,and it has made great contributions to promoting economic development and relieving traffic pressure.As the command center of railway operation,the centralized dispatching system unifies the dispatching,plans the operation and coordinates the work of various departments of railway transportation.The working level and functional quality of the operators in railway operation,especially those in dispatching,will directly affect the operation efficiency of railway and affect the safety of trains.The rapid development of the railway has greatly increased the training needs of railway operators.Since field equipment is used for railway operations,there are few opportunities for operators in operation related industries to conduct training,especially for joint training.So the analysis and design of the railway multi-service joint simulation training system is of great practical significance for the training of the related operators.Based on the existing railway comprehensive operation simulation training system and the actual needs of the railway site,this thesis develops relevant practical scenarios based on the actual faults,abnormal conditions and related standard operations of the railway site,combined with the actual training needs of the teaching and business skills,to schedule operations for the CTC operators of the job types involved in the relevant scenes conduct joint training on the integration of theory and practice,and conduct subjective and objective assessments of the trainees according to the relevant disposal processes and operation skills of the scenes.This thesis mainly includes 4 parts.(1)Study the existing centralized dispatching system,analyze the functional topology of the CTC system,and learn the dispatching and command operation flow.(2)Analyze the functions and training needs of railway multi-service joint operation,design the overall implementation plan of the system.This system is divided into 5 subsystems: trainer training management system,traffic dispatching simulation system,station operation simulation system,train driving simulator system,and ground environment server.Conduct demand analysis on each system.(3)Design the detailed functions of the trainer training management system,traffic dispatching simulation system,and station operation simulation system,focusing on the process flow of course editing,managing,and evaluating the course scene in the trainer system.Taking Visual Studio as the integrated development environment,MFC and QT framework are used for interface development,combined with SQL Server database,TCP / IP protocol,fault injection and other technologies to implement system functions.(4)Use the line data of the Cheng Sui high-speed railway to verify the function of the railway multi-service joint simulation training system and test the system simulation and training functions.According to the verification results,the railway multi-service joint simulation training system designed in this thesis can conduct standard and failure scenario training,evaluate the training results of the participating trainees,which can effectively reduce training costs and improve training efficiency,and reduce the burden on teachers.
