The Design And Realization Of Train-travel Simulation System Base On3D Scene

In the graphics technology becomes more mature, visual simulation technology becomes more widely used in the national economy and national defense and other fields. In rail transport, trains and passengers, the technical staff to better grasp the rail transport related technology required for effective skills training, because the particularity of rail transport is often difficult to skills training and on-site practice, training and practice the skills of touch makes training efficiency is not high. The use of visual simulation intuitive and immersive can effectively compensate for this lack of visual simulation also has economy, flexibility, security and repeatability, etc., will be more and more applications in skills training and simulation experimental and other fields.This article uses the VC++platform and OpenGL graphics interface as a development environment, a three-dimensional simulation of train operation process perspective. Train operation according to the needs of drivers in the system by adding train, railway signaling systems, and is closely related technology train operation simulation.This system design includes the following aspects:1, According to the requirements, design system solutions, and the system is divided into four sub-levels:three-dimensional model layer, model-driven layer, data models and logical layers, lay the foundation for the system development work.2, Using a variety of three-dimensional modeling techniques to construct3D world of train operation, constitute the three-dimensional world of the visual object modeling, design, model-driven. System visual objects divided into two categories:Natural class object and rail facilities and equipment objects.3, The two types of train operation control signal system control logic simulation, the realization and the station interlocking section block basic functions, on this basis, the design model drive train, train control model running on different paths, a true reflection of the train state of motion. Finally to complete the traction, braking, train control and other functions train driving simulation.This finally realized based on three-dimensional visual simulation of train operation system, to achieve the desired design goals.
