Design And Application Of Rail Traffic Driving Simulation System

With the rapid development of rail transit in China,there is a growing demand and quality requirements for talents in rail transit.However,the relevant real equipment is expensive and has many specification limits.Moreover,the training cannot interfere with the on-site operation.In order to meet the needs of training teaching and scientific research,the relevant departments use the rail traffic driving simulation system to simulate the field equipment and the route environment.The method is low cost,and can train students through repeated practice so as to help them understand the operation process,be familiar with various application scenarios,master the method of fault handling,and develop emergency capabilities in emergency situations.In addition,the simulation system can be combined with the train dynamics model,the Automatic Train Protection model and the Automatic Train Operation model to realize the simulation and carry out the related experiments to verify the scientificalness of the related operation control algorithm and save the research cost.The design and application of rail traffic driving simulation system is studied in this thesis from two aspects:train-teaching function and research function.In this thesis,the rail traffic driving simulation system is designed and implemented by simulating the train console which based on Communication Based Train Control system.The system requirements and functional requirements are analyzed and the working principles are elaborated.The system is divided into man-machine interaction layer,logical judgment layer,data processing layer and information interaction layer.Firstly,the design of human-computer interaction layer and logical judgment layer is completed on the basis of the study of the layout and control logic of the actual console.Secondly,in order to complete the design of the data processing layer,the train dynamics model,the ATP automatic protection model and the ATO automatic running model are designed according to the traction specification,the ATP algorithm,the ATO algorithm and the related technical standards.Finally,the design of the information exchange layer is completed by using the UDP communication protocol to realize the information interaction with the Zone Controller and the Automatic Train Supervision system.In this thesis,LabVIEW is used as the programming language to complete the simulation of the rail traffic driving simulation system.And each submodule of the system is functionally tested.The test results show that the system interface interaction function,mode conversion function,simulation function of train operation control and communication function run well,and achieve the expected goal.The system can simulate the functions related to hardware devices,installed as a standalone system on a personal computer to simulate driving training and scientific research.In addition,the system has practical application in the laboratory CBTC system,and establishes communication with ATS,ZC,sand table and simulation train,and the joint debugging operation is normal.
