Research And Implementation Of EMU Communication Simulation System Between EMU And Ground

With the great development of railway,Railway transportation equipment, locomotives and rolling has changed from the traditional train to EMU which has a higher demand to real-time and accuracy communications of vehicles.By using of computer simulation and simulating the actual running of EMU,the realization of EMU vehicles real-time communications to understand status information of EMU is very necessary.In this paper,the objectives of the study is simulating automatic communication between EMU and ground,we strive for breakthrough in real-time and accuracy,which will provide some referenced value for our railway information construction integrating with the world.Firstly,The paper present the research significance of the communication between EMU and ground,then we analyze the theory of the communication between EMU and ground.On the base of detailed analysis of the needs,we divide the system into four parts according to the information system,communication service and data flow:EMU Simulation System,EMG Simulation,LAIS Simulation,Ground Data Handling System. Against the parts,the paper gives out the design proposal and concrete implementation. EMU Simulation System simulates the running of the EMU which is used to generate status data.After information collection,handling,data is transmitted from EMG Simulation to LAIS Simulation.Information is handled in LAIS Simulation and then it is transmitted to the ground,as soon as the ground receives the information,it will analyze,save and display the information,which achieves the real-time communication between EMU and the ground.The research result of the paper has experienced and verified on the CRH2 EMU and in the lab.We also make some accuracy and real-time analysis.EMU Communication Simulation System between EMU and Ground provide some important decision support to the security traffic of EMU.
