【摘要】 车站列控中心是客运专线列控系统的核心设备,它不仅要实现控制有源应答器的报文输出和临时限速的核对与执行,还要负责ZPW-2000A/K轨道电路的编码、区间信号机点灯逻辑、站间通信、区间及站内轨道电路改方等逻辑功能。列控中心担负着列车行车安全的重大责任,因此很有必要对其进行深入研究,以完善列控中心功能,但其功能强大、结构复杂、通信接口众多、造价高昂,在学校实验室条件下要对列控中心进行实设备研究是难以实现的。仿真作为一门综合性学科已有多年历史,仿真用模型代替实体,具有经济、安全和试验周期短等特点。利用计算机仿真列控中心的有源应答器报文生成过程、模拟临时限速命令的核对与执行的交互过程、控制LEU输出有源应答器报文,不仅大大节约了列控中心设备的试验费用,并与轨道电路编码模块、区间轨道电路改方模块相结合,对研究客运专线列控中心的功能具有重要现实意义。论文的主要内容包括绪论,客运专线列控中心仿真系统分析,有源应答器报文模块分析,车站有源应答器报文数据分析,有源应答器报文生成与临时限速处理实现等部分。论文在分析列控中心仿真系统的基础上,对有源应答器报文生成与临时限速处理模块进行需求分析;根据软件设计原则结合本系统的具体要求,进行系统软件的总体设计;文中描述了系统主要功能:有源应答器进路报文的生成,临时限速命令的校核和执行,临时限速报文包的临时生成,有源应答器报文的组包发送。最后通过系统联调,很好地达到了列控中心功能仿真的目的。更多还原

【Abstract】 The train control center of train station is the core equipment of train control system in passenger railway lines. It is not only active to achieve the control of active balise message output and the checking and executing of temporary speed restriction,but also responsible for those functions such as ZPW-2000A/K track circuit code,the logic of section signal lighting, inter-station communication, direction-changing of section and station.The train control center takes on the major responsibility for traffic safety,therefore,it is necessary to do some research and improve the function of it.However, the constructure and functional requirements are so complicated, and there are too many communicaton interfaces, and it costs a lot. So it is difficult to do research with actual equipments in laboratory circumstances.As a comprehensive method which has been using for many years, simulation has replace the entity and has character of economical, safe, and efficiency.The computer simulation includes active balise message generation process, the check and execution of temporary speed restriction, and the output of active balise’s telegram, and the application of the model such as track circuit code and direction-changing in section, this method means too much about saving expenditure and research on the actual train control center.The main contents of this dissertation includes introduction,the analysis of train control center simulation system, analysis of active balise telegram module,the analyses of active balise telegram data, and the generating of active balise telegram and the managing of temporary speed restriction.Based on the analysis of the simulation of the train control center system, this dissertation analyzes the requirement of the generating of active balise telegram and the managing of temporary speed restriction module. The software design is under the standard for software design principle and system demands. This dissertation describes the detail design method of the primary function modules which consists of generating of active balise route telegram, check and executing of temporary speed restriction, the generating of temporary speed restriction telegram, and active balise telegram packet and sending. At last, it has well reached the purpose of systematic function simulation through debugging systematically.更多还原
