High-speed Railway Signal Simulation Training System

In recent years,with the continuous improvement of comprehensive national strength and the continuous progress of science and technology,high-speed railway has developed rapidly and the speed of trains has become faster.China's high-speed rail has begun to become the business card of the world under the strategy of “one belt and one road”.With the increasing operation scale of high-speed railway and the increase of new sections and stations,the structure of high-speed railway network has been improved gradually.The rapid development of high-speed railway can't be separated from the development of technical equipment and the support of skilled technicians.The skilled and correct use of Centralized Traffic Control System(CTC)by railway scheduler staff is the precondition of ensuring the safe operation of train.The operation of railway scheduler staff must be accurate.Once the operation is improper,the railway accident will bring the railway transportation an unpredictable loss.As the using equipments of CTC is in the working condition all day,it is impossible for the newly dispatch staff to carry out the operation drill directly on the field equipment,which brings great trouble to the new recruits training work.The traditional teaching and training mode lacks the combination of theory and field operation practice,which leads to the new railway employees can't adapt to the working environment quickly and students can't really master the working principle of the equipment.Therefore,it is important to design and develop CTC center simulation training subsystem with teaching training function.Firstly,this thesis analyzes the hierarchical structure and function principle of CTC system in high speed railway dispatching and determines the general demand of CTC center simulation training subsystem.According to the different needs of the training personnel,the simulation and training requirements of CTC center simulation training subsystem are defined.Secondly,according to the overall demand of CTC center simulation training subsystem,the CTC center is hierarchical analyzed and functional modules are divided.The overall design scheme of CTC center simulation training subsystem is proposed.The train diagram module,command delivery module,station control module,communication interface module and training examination module are analyzed and designed in detail.Finally,the function modules of the simulation training system of CTC center are programmed with C++ language based on the MFC framework of Visual Studio 2005 platform.The simulation training subsystem of CTC center adds abundant training content,realizes the basic theory training and practical operation training of trainers,and enhances the participation of trainers by means of text display and voice interpretation.At present,the high-speed railway signal simulation system has been put into use in Lanzhou Railway Administration,Lanzhou Jiaotong University,Lanzhou Institute of Technology and other places.It is convenient for railway staff and students to learn systematically from the system structure and function to the operation and maintenance of specific equipment in the process of training and teaching experiment.
