CTCS-2 Train Control Simulation Training System

High-speed railway train control system is the key technology and core equipment of high-speed railway signal system to ensure safe operation of the train and improve transport efficiency.With the increasing density of Chinese high-speed railway network,promoting the belt and road and investing a large number of high-speed rail line into operation in recent years,the scarcity of utilization and maintenance personnel of high-speed rail equipment has become a bottleneck restricting the development of the railway industry.As an important part of the train control system,the safe and stable operation of vehicle equipment is closely related to the technical level of the train driver and the maintenance personnel.How to improve technical level of the railway frontline workers has become an urgent problem to be solved by the railway transportation department.Due to security and many other factors,on-site vehicle equipment provides students with less chance of principle of teaching and operating practice.Therefore,the development of a set of high-speed railway train control simulation training system has important practical value and practical significance.Firstly,this paper expatiates on the structure of CTCS-2 train control system,the basic functions and working mode of the vehicle equipment.On this basis,training system user needs,entire simulation training system requirements and vehicle training subsystem functional requirements to be analyzed.According to the specific needs of different groups,such as high-speed railway train drivers,vehicle equipment maintenance personnel and college students,training contents are analyzed in detail.Secondly,overall design and implementation scheme of the vehicle training subsystem are put forward.In order to improve training effect and make training system closer to the actual operating situation,CTCS-2 train control simulation training system selects high-speed railway station,relay station and non-distribution station of CTCS2 and CTCS0 standard station which are consistent with the scene in the station design.Besides,CTCS2 section and two-line four-aspect automatic block section are selected in that design.According to design of functional architecture of the vehicle training subsystem,the function is divided into simulation function and training function.Simulation function includes simulated driving interface,train overspeed protection,information receiving and processing,train operation calculation,train operation record and train operation control.In addition to detailed analysis and design of the three simulation function modules including simulated driving interface,train overspeed protection,information receiving and processing,the training function module and communication protocol are also analyzed and designed in detail.Finally,the thesis takes Visual Studio 2005 as the development platform of vehicle training subsystem,completing the development of vehicle training subsystem by computer simulation technology and object-oriented development method.This method has achieved a complete simulation of vehicle training subsystem and completed basic knowledge training,basic operations training of vehicle equipment,train operation scene display,vehicle equipment failure training and other training functions on this basis.The vehicle training subsystem integrates a wealth of training cases that participating students can choose selective learning according to their own needs.At the same time,the vehicle training subsystem can cooperate with other subsystems to realize overall function display of the whole train control system in different types of stations and different format sections.Currently,the system has been installed,debugged and tested in the high-speed railway signal system comprehensive laboratory of Lanzhou Jiaotong University.To a certain extent,the system improves the basic theoretical knowledge and practical operation ability of the students from the feedback information of the trainees.
