Design And Application Research Of Train Control Center Simulation Training System In CTCS Level-3

Train control center is the key technology and core ground equipment in train control system to improve the transportation efficiency and ensure the safety.With the continuous updating of Chinese high-speed railway signal technology,the promotion of the Belt and Road,and more and more high-speed lines are put into operation.The railway team at the scene urgently needs a group of high-level signal equipment operation and maintenance personnel.The training of railway front-line staff and students has become the bottleneck of railway safety operation.The field equipment is generally in all-weather working condition.It is impossible to provide students with opportunities for theoretical training and practical operation.It is of great practical significance to develop a set of train control center(TCC)simulation training system for college students and field personnel that is highly close to the actual scene,simple and easy to understand.This thesis firstly analyzes the research status and existing problems of the TCC simulation training system,describes the system structure,basic functions and system interfaces.According to relevant technical specifications and the overall functional requirements of the TCC,the overall functional framework and simulation model of the system were established.Aiming at the many shortcomings of current experimental teaching and traditional training mode,the thesis analyzes the user needs of students and personnel.Secondly,it is proposed to design the overall scheme of the system in a hierarchical way,which is divided into two functional modules of simulation and training.The function modules such as the balise arrangement,the encoding function of the track circuit,the function definition of the balise packet,the message preparation and the processing of the temporary speed limit information are designed.In order to get closer to the actual operation scene,the training module covers more station types.The design of the stations selected the high-speed railway station,relay station,as well as the teaching materials in 6502 standard example station.Finally,the thesis uses the object-oriented software development technology to program each functional module under the system development platform of Microsoft Visual Studio 2005.It realizes the human-machine display interface,operation and maintenance terminal,balise message query,track circuit carrier frequency information display,train control data playback,online examination training and other functional modules.The system can work normally according to the expected effect after the joint test.Train control center simulation training system integration of a variety of training cases.Participants can learn basic signal knowledge,train station operation and safety knowledge on the system platform.At the same time,with the cooperation of other signal subsystems,it can complete the whole line simulation running in complex scenes and various fault states.Through the interactive way of text display,voice broadcast and online test and evaluation,the system enables users to have a good experience process and training effect.
