CTCS-2 Train Control Simulation And Training System

Railway signal technology is developing rapidly in China,railway signals equipment and system update frequently.With the continues emergence of new technique,it is necessary for the signal equipment maintenance personnel and the train operation technicians to master the relevant technology quickly.Students in the school can have an experimental platform which is combined with actual closely,and have a deeper understanding of the principle and structure of the new technology.An experimental platform is needed to support the cutting-edge technology research of researchers and teachers.In order to solve the disadvantages of the traditional training mode,according to the actual application of the train control system in the field to simulation,and join the training function.The use of advanced computer simulation technology to develop a complete set of train control simulation and training system.Integrated with the basic principles of the train control system,the structure of the framework,interface module,data flow,transparent display,training and other functions.Firstly,this paper focuses on the characteristics of the system structure,functional principle and system interface of the temporary speed restriction subsystem.In view of the deficiency of traditional experimental teaching and training mode,the system will integrate a variety of practical operating scenarios that in order to adapt to different training objects and make the system coincide with the actual operation of the scene.Integrating the training function in the human-computer interaction interface,including the basic theory of train control system,operation of the temporary speed restriction command,temporary speed restriction common fault solution and temporary speed restriction subsystem maintenance training.Secondly,according to the functional requirements of the temporary speed restriction subsystem to design the overall framework.It includes a special railway line standard station for passenger transportation,existing railway standard station,block interval,repeater and no distribution station.Special railway line standard station for passenger transportation,the block interval between Shanghai and Beijing constitute a closed loop formed a three-station and four-interval ring structure.The simulation training subsystem includes temporary speed restriction subsystem simulation,dynamic display interface,selection of training customer,scene training examination management and so on.And the structure and function of each function module are described respectively.The key points are to discuss the temporary speed restriction command workflow,logic verification,management of temporary speed restriction command at boundary,design and implementation of the communication protocol between the temporary speed restriction subsystem and other subsystems.Finally,application of Visual Studio 2005 development tools,based on MFC,using VC++ programming language to complete temporary speed restriction simulation and training subsystem.Using modular design ideas to achieve the function of each module,communication with other subsystems.And complete the joint debugging and commissioning of temporary speed restriction subsystem and other subsystems.The system is fully integrated with all kinds of practical signal basic equipment status and train travelling function.It is embedded in training demonstration,operation test,theory examination and other functions.It can help students study and operation by themselves.The system not only simulate the conventional fault state,but also conduct training for complex scene analysis.Through precisely positioning and trouble-shooting to teach students step by step.Let students master solution of common failure in essence.Training function can use voice and text to explain the interpretation example,targeted topic test and automatic verification of the results.It has good interaction and user participation functions.
