高速铁路综合调度仿真系统时空一致性的研究

Study on the Time-space Consistency of the High-speed Railway Integrated Dispatching Simulation System

随着计算机网络技术的发展,分布交互式仿真成为现代并行仿真技术之一并且得到广泛的应用。仿真时钟的推进是分布交互式仿真系统的关键技术。在对高速铁路综合调度仿真系统分析的基础上,指出综合调度仿真系统是一个混杂系统并对仿真系统中的关键技术———仿真时钟的推进,进行了详细的分析研究,提出了基于仲裁技术的仿真时钟推进算法,并在实际中加以应用。

Along with the development of the computer network technology, DIS (Distributed Interactive Simulation) is becoming one of the modern concurrent simulation technologies and is applied widely. Simulation clock pushing is the key technique in DIS. On the basis of analyzing the high-speed railway integrated dispatching simulation system, this paper points out that the integrated dispatching simulation system is a hybrid system, studies the key technology-simulation clock pushing-in detail, and presents the simulation clock pushing algorithm based on the arbitration technology.
