摘要
在虚拟编组系统中多列车形成虚拟编队运行,自动驾驶技术能够实现高精度速度/位置控制,提升列车运行效能。自动驾驶与虚拟编组条件下的列车运行过程将集中运行控制、调度指挥、自动化驾驶为一体。本文首先从概念与关键技术两方面分析了虚拟编组特性,其次分析了列车自动驾驶系统特性;从列车受力与运行动力学方程及其研究方法原理方面分析了单列车运行过程,最后系统分析了多列车编队运行模式。旨在促进列车运行控制与运输组织管理体系整合向综合自动化与自主化方向发展,为新一代轨道交通运营管理技术体系的建立提供参考。
Multiple trains run in formation in the virtual coupling system. Automatic train operation(ATO)can realize the speed/position control with high precision, so as to enhance the efficiency of trains run. The train operation process under ATO and Virtual Coupling can integrate the operation control, dispatching, and automatic driving. Firstly, this paper analyzed the features of virtual coupling from perspectives of conception and key technique, then it analyzed the ATO characteristics. From the points of train forces and dynamics equations of train operation as well as its related principles and methods for research, it analyzed the operation process for single train. Finally, it analyzed the operation modes of multiple trains formation. The purpose of this paper is to promote the integration of train operation control and transportation organization system towards the direction of comprehensive automation and autonomation, and to provide the references for the building of rail transport operation and management system of the new generation.
