【摘要】 随着城市轨道交通的迅速发展,对各类地铁运营人员的需求大增。传统的培训方式由于费用高、效率低,已无法满足要求。在这种背景下,利用计算机仿真技术来进行培训的方式应运而生,这种方式不仅费用低,而且效率高。而地铁行车调度仿真培训系统作为整个OCC(运营控制中心)调度仿真培训系统的重要组成部分,将为OCC行车调度人员的培训提供强有力的支持。行车调度仿真的核心内容是模拟线路上车流(简称虚拟列车群)的运行情况,为整个轨道交通综合仿真培训系统提供所有列车对象仿真模型,每一列车模型都是以牵引计算理论为基础,建立运行模型,列车由虚拟司机驾驶,列车的运行受信号系统和运行图的约束。当前国内对列车群的研究,主要是针对列车运行图的铺画和运行线的调整,仿真模块大多是模拟列车按铺画的运行图运行的情况,对线路条件、列车特性及信号系统特点处理的都比较简单。因此,本文对虚拟列车群的设计与开发具有非常重要的现实意义。本文结合地铁OCC行车调度仿真培训系统的功能,在对虚拟列车群功能深入了解的基础上,对虚拟列车群模块进行了设计开发。本文首先明确了行调仿真培训系统的功能、组成以及列车运行相关基础环境；然后,针对城市轨道交通列车运行之特点,对虚拟列车群进行功能需求分析；在此基础上,对列车群模块进行了详细的设计与实现,主要包括：虚拟司机数据结构的设计及实现；列车运行模型的建立及具体实现；ATP的建模与实现；列车群控制管理功能的设计与实现。最后,将虚拟列车群模块应用到行调仿真培训系统中,结合该仿真培训系统的功能,对列车群功能进行了测试与验证。并具体从两个案例出发,阐述列车群功能的仿真实现及该系统对行调人员的培训功能。仿真结果表明,将此列车群模块应用到仿真培训系统中,不仅能为调度员提供一个真实的运营环境,还能验证线路的通过能力,并能模拟各种非正常行车,实现对调度人员的培训功能。更多还原

【Abstract】 With the rapid development of the railway,more and more railway dispatchers are needed.Because of too much expense and low efficiency the traditional way of training railway dispathers hasn’t already met the requirement. So that a kind of new training way that using computer simulation technology to train railway dispathers emerges,which is low expense and high efficiency.And OCC traffic dispatcher simulation training system is an important part of the OCC dispatcher simulation training system.It will provide strong support for the railway traffic dispatcher training.Simulating the operation of train flow on line (virtual train group) is the core content of the OCC traffic dispatcher simulation.It provides all the train simulation model for the entire rail transit comprehensive simulation training system.Every train establishes the operation model on the basis of traction calculation theory.The train is drived by virtual driver,and constrainted by signal system and train diagram.Nowdays,the research of train group at home is mainly to aim at the shop painting and adjustment of the train diagram, and the line condition, train properties and characteristics of signal system treatment are quite simple.Therefore, in this paper,the design and development of virtual train group has very important practical significance.Combined to the function of the metro OCC dispatching simulation training system the virtual train group is designed and developed on the basis of the realization of the function of the virtual train group.This paper first introduces the function and composition of the simulation training system and the basic environment related train operation.Then,combined to the characteristic of train operation,virtual train group has been made detailed functional requirement analysis.Then,the modules are designed and implemented,including the design and implement of data structure for virtual driver,the modeling and implementation of train operation,the modeling and implementation of ATP,the design and implemention for train group control management function.Finally,the virtual train group is applied to the simulation training system.Combined with the function of the simulation training system,the function are tested and verificated.And from two concrete cases,this paper expounds the impletement of the simulation of train group and the function for training dispatchers.The simulation results show that the train group module is applied to the simulation training system,not only can provide the dispatcher a real operation environment,but also can verify the ability of the line through,and can simulate various abnormal driving,realize the dispatcher training function.更多还原
