摘　　要：研究了一种基于虚拟现实技术的视景仿真系统,并将其应用于地铁列车运行控制仿真系统中。设计了基于数值分析的通信数据的拟合算法,很好的解决了视景输出的实时性问题。从视景仿真模块与列车运行仿真平台间的通信、场景模型的建立和简化、视景仿真程序等方面对该系统进行了介绍,并给出了视景仿真结果。该仿真系统已应用于北京地铁环线基于通信的列车控制(CBTC)实验线路的研究与开发。A visual simulation system based virtual reality was introduced and the system was implemented in trains operation control simulation system. The algorithm of data fit was_designed according to the analysis of numerical value, and the problem of the visual output in real-time was resolved by the algorithm. The system was reviewed from the communication between the visual simulation and the platform of simulation system, the establishment and predigestion of model environment, and the visual simulation software. Based on personal computer as hardware platform, this visual simulation system has been used in the Beifing metro simulation system based on CBTC technology.
