Research On Automatic Train Operation Based On Urban Rail Trainsit 3D Simulation System

With the rapid development of China's rail transit industry,more and more simulation studies have also been applied to the field of rail transit by scholars.Similarly,as a kind of simulation technology,three-dimensional simulation technology is increasingly applied to the field of rail transit.In this paper,a laboratory's three-dimensional simulation system for subway trains based on MSTS(Microsoft Train Simulation)is used and the train client of the 3D simulation system is used as the research object.Combined with actual ATO,ATO simulation system is designed and the single train client's automatic operation is implemented on the 3D simulation platform.This paper makes use of 3D simulation resources and uses the reserved interface function to connect the designed ATO simulation system to the 3D simulation synthesis platform.It is hoped that the structure and function of the entire platform will be improved and a comprehensive simulation platform for the urban rail transit ATC system will be built up based on 3D simulation.First,this paper introduces the 3D simulation comprehensive platform,including the 3D simulation system and interface function and summarizes the real ATO's structure and function then leads out the work of this paper.Afterwards,the overall design and overall implementation of the ATO simulation system are described separately which are realized in combination with database,and the difference between the simulation system and the actual ATO system and the reasons for the differences are explained.Combined with the summary of the operation strategy,this paper designed the core control algorithm.In VS2013,the ATO simulation system is implemented by C# object-oriented language,and this paper realizes the connection to the ATS simulation system and the train client of the simulation system respectively and implements the test of automatic operation of single tarin object in 3D simulation sysytem.Finally,the ATO simulation system is tested and compared with the driver's driving.The test results reach the proposed functional requirements,and the parameters affecting the performance of the ATO simulation system are proposed.The simulation of the train control system is applied to the 3D simulation platform successfully.
