【摘要】 我国高速铁路已进入了快速发展时期。为了确保高速列车的安全运行,迫切需要装备性能先进、安全、可靠、高效的列车运行控制系统。CTCS3级列控系统是基于无线通信实现列车车载设备与无线闭塞中心(RBC)的双向信息传输的列控系统,其中列车自动防护系统(ATP)是整个列控系统车载设备的核心,它的主要任务是对列车运行控制信息进行综合处理,生成目标—距离模式曲线,监控列车运行速度,实现列车的自动超速防护。本文在剖析CTCS3级列控车载设备结构和功能的基础上,对基于通信的列车防护系统(ATP)关键算法和模型进行了深入研究。本文首先介绍了国内外列车控制系统的发展与现状,阐述了国内车载设备的发展现状。然后,在分析国内、外典型的ATP安全制动模型的基础上,分别对这两种安全制动模型进行了仿真计算,并对仿真结果进行了比较。针对列车出现空转、滑行时会对列车制动距离产生影响,本文讨论了车载ATP对空转、滑行两种列车特殊运行工况的检测方法,并对空转、滑行下测速、测距方法进行了研究,并在此基础上对之前建立的安全制动模型进行了相应的修正。为了验证国内典型安全制动模型的可用性,本文分析了CTCS3级系统车载设备组成结构、功能、接口等需求,对车载ATP以及人机交互界面DMI进行了仿真,实现了包括：最具限制速度曲线合成、不同工作模式下速度防护曲线的计算、超速防护、工作模式切换等车载子系统主要功能。更多还原

【Abstract】 Our country’s high-speed railway has already been in the time of rapid development. In order to assure operation safety of high-speed railway, train operation control system that is advanced, safe, reliable and efficient is necessary. CTCS3 train control system is based on the wireless communication to implement the two-way information transmission between train-borne equipment and Radio Block Center (RBC), while ATP (Automatic Train Protection) is the core part of the whole train-borne equipment. ATP’s main task is to process integratedly train operation’s control information to generate distance to go model curve, monitor train speed and achieve ultimately the train’s automatic over-speed protection.Based on the analysis of the structure and function of CTCS3 train-borne equipment, this paper studies deeply in key algorithms and models of the ATP based on communication. Firstly, this paper describes the development and current status of domestic and international train control system and elaborates the development and current status of domestic train-borne equipment. Then on the basis of analyzing domestic and foreign typical ATP safe braking model, the two models are simulated respectively and the simulation results are compared. Against the affect of train’s spin and slide, this paper discusses the train-borne ATP’s detection method of two special operation conditions of spin strain and slide train, studies the method about the measuring speed and distance in the condition of spin and slide and amends accordingly the established safe braking model formerly.In order to verify the availability of domestic typical safe braking model, this paper analyzes the requirements of CTCS3 train control system equipment’s composition, function, interface and so on and simulates the train-borne ATP and DMI (Driver Machine Interface) to implement the main function about train-borne subsystem including synthesis of most restricted speed profile, the calculation of speed protection curve of different models, speed protection, mode switch and so on.更多还原
