The Design and Implementation of Urban Rail Transit Driving Simulation System Based on Real Scene

Driving simulation systems in urban rail transit are widely used in teaching demonstration, pre-service training and engineering theory research or other fields. The high-precision, large-scale, real-time interaction of simulation has been a goal of researchers. How to coordinate these parameters according to demand, and optimize algorithms and frameworks are currently a hot research. This paper presents the idea of using real scene modeling technique to develop large-scale urban rail transit driving simulation system. Real scene modeling technique has many advantages, including 1) Strong sense of the scene and high experience, 2) The process of production is simple and fast, 3) High scalability and compatibility. Accordingly, designed system can achieve these features: multi-train and multi-line's co-simulation, real-time interactive experience of user and different-location synchronous compatibility. This paper focused on solving massive real-scene data processing, construction and real-time synchronous adjustment of timeline, automatic generation technique about the real-scene model of large-scale rail network, and other technologies. In the case of Fangshan line Beijing. The design includes collection, filter and process of data; implementation and deployment of the system, effectiveness analysis and other embodiments of the steps. The results show that: the plan and system this paper designed can be implemented, taking into account the balance of precision and efficiency, and has a strong promotional value.
