Research And Implementation Of Simulation Teaching Platform For Train Operation Diagram

High-speed railway traffic scheduling and establishment of train operation diagrams are used to coordinate the work of various departments of rail transport,which can ensure safe and punctual operation of trains,and improve the quality of train services.Besides teaching students a wealth of theoretical knowledge,colleges and universities should translate theory into practice,teaching students the ability of practical operation.So modeling of the locomotive to get various parameters and form graphics,is more intuitive and real.The platform is used for qualitative simulation analysis of the trajectory of the train diagram and the simulation of the station and train entry and exit situation,which hardware circuit of lower position machine as a crew stations and trains and the host computer as a control center.The host computer is used to simulate the entry and exit situation,and complete the drawing of the train diagram.The lower position machine uses IAR for MSP430,which completes the serial port initialization and the control of the peripheral module.According to the data,the host computer controls the lower machine and completes real-time control and real-time action through the serial port.The platform takes MSP430F149 as the main chip to build train operation diagram simulation Teaching platform which has the main power module,communication module andrelay control module.To complete the host computer instructions,the host computer using visual studio 2015(C#)winform builds the host computer platform.It mainly includes manually entering data for the users,data processing and integration,formation of the operation diagram based on data,and complete the communication process in the train cursor.Through system debugging of the upper and lower machines,it finally shows that the lower position machine can give real-time action and feedback data according to the host computer command.As the control center,the platform can provide for the users the graph data recording and analysis of run charts,which can meet the teaching requirements and the purpose,achieving desired operational results.This platform is very important for the research and teaching of train operation control and railway traction system safety.
