|
摘要
为了采用计算机仿真技术研究CBTC系统,构建了基于计算机,网络及虚拟现实技术的CBTC仿真测试系统。其所提供的可视化线路及列车仿真运行环境具有可控性、无破坏性、安全性、可重复性和经济性以及可实现性等显著优点。虚拟现实作为仿真测试中的人机互动接口及仿真过程及结果的直观体现载体,是系统中不可或缺的一部分。
本文对虚拟现实和CBTC仿真测试系统做了简要介绍,针对原有三维视景显示系统所存在的不足,重点研究了如何使用虚拟现实关键技术为CBTC仿真测试系统构建一个更为先进、方便、实用、逼真的显示系统。
论文将虚拟现实关键技术与CBTC仿真测试系统实际要求相结合,通过实物虚化、动态模型、多视点显示、人机交互及声音仿真技术的运用,真实的再现了CBTC仿真测试环境,可实现单车仿真运行,多车追踪仿真运行,不但可用于运行控制策略,系统集成方案分析,也可用于关键子系统测试及系统集成测试等方面。
最后,本文给出了CBTC仿真测试系统在试验线上的实际应用,具体叙述了针对试验线实际情况构建虚拟现实环境的过程和所使用的关键技术。此次仿真测试过程中,虚拟现实在前期实验室测试和后期现场测试中,提供了真实流畅的显示效果和方便高效的人机交互,为系统的成功应用做出了贡献。
In order to research the CBTC system with computer simulation technology, the CBTC simulation and test system is built based on computer, network and virtual reality technology. Visual simulation environment is provided for line and train simulation, the platform is controllable, safe, repeatable, economic and realizable. As the human-machine interface and visible display platform of the simulation and test, the virtual reality is one of the indispensable parts of the whole system. The CBTC simulation and test system and virtual reality are briefly introduced in this paper, because the former 3D display platform has some defects, the application of virtual reality key technology in the system is emphasized in order to compose an advanced, convenience, practicable and vivid display platform for the CBTC simulation and test system.
The requirements of the system and the key technologies of virtual reality are adequately considered, by applying the technology of real-time modeling, dynamic model, multi-viewpoints display, human-machine interaction and sound simulation, the CBTC simulation and test environment is vividly recurred so that the system can simulate single train running and trace of multi-trains. Also, operation control policy and system integration scheme can be analyzed, key subsystem and system integration can be tested by using this system.
Finally, the actual application of the CBTC simulation and test system is provided. The process of creating the virtual reality environment and the usage of the key technology are concretely described. The virtual reality provide the system with vivid and smooth display effect and convenient and effective human-machine interaction during the prophase test in the libratory and anaphase spot test, contribute to the success of the simulation and test system.
