【摘要】：随着城市交通拥堵问题的日趋严峻,城市轨道交通在运量、速度、建筑用地、安全和环保等方面的优势受到了各国政府的重视,并已经成为各大城市基础设施建设发展的重点。然而,轨道交通的快速发展、列车车辆技术的不断提高,使得列车发生故障的概率也不断提高,并且故障类型日趋复杂,因此保障列车运行安全成为轨道交通发展的重中之重。传统的安全监测方法简单单一、相互独立、彼此之间缺乏联系,难以从总体上把握列车的运行状况,为了适应轨道列车的发展速度,进一步提高轨道列车的运行安全系数和设备运行效率,研发新一代综合性的城轨列车安全监控系统已经刻不容缓。本文在传统列车安全监测系统的研究基础上,提出了一种基于以太网技术的综合性城轨列车安全监测系统,该系统很好的弥补了传统监测系统在传输速率、吞吐量、传输协议和数据共享等方面的缺陷。具体来讲,本文的研究工作包括以下几个部分： (1)首先,通过对国内外列车安全监测系统的发展现状研究,指出了当前监测网络存在的主要问题。针对这些问题,提出了一种结合以太网和总线网络技术的新型网络架构,并对该网络的网络结构、监测设备、数据流向、通信协议、数据解析和存储过程进行了分析研究,满足了新时代对城轨列车安全监测网络提出的一系列要求。 (2)其次,根据城轨列车安全监测系统的数据存储和管理需求,本文利用关系型数据库,对系统数据存储的表单结构进行了研究设计。数据库的设计规范了系统内部数据的存储形式、降低了数据冗余度、节省了数据存储空间、提高了数据利用率、共享率以及查询效率,此外也为系统软件管理平台的开发奠定了基础。 (3)再次,本文运用模块化的设计思想,设计了城轨列车安全监测系统软件管理平台。该平台完成了系统用户管理、系统设备管理、设备实时状态监测、历史数据查询、报警信息查询、数据报表生成以及故障统计分析等一系列功能,为系统管理提供了一个友好的管理界面,对于提高了管理人员的工作效率、保障列车运行安全有着重要意义。
[Abstract]:With the increasingly serious problem of traffic congestion in the city, city track traffic in the traffic volume, speed, construction land, safety and environmental protection and other advantages has been the attention of governments, and has become a major focus of the development of city infrastructure construction. However, the rapid development of rail transportation, vehicle technology continues to improve, probability so the train fault is also rising, and the fault type is complicated, so to protect the safety of train operation become the priority among priorities of the development of rail transportation safety. The traditional monitoring method is simple and independent of each other, the lack of contact between each other, it is difficult to grasp the running status of the train, in order to adapt to the pace of development of railway train. To further improve the efficiency and safety of operation equipment for railway train, development of a new generation of comprehensive urban rail train safety monitoring system is imperative.
Based on the research of the safety monitoring system of the traditional train, put forward a comprehensive city Ethernet rail train safety monitoring system based on the system, it makes up for the throughput of traditional monitoring system in the transmission rate, transmission protocol and data sharing aspects of defects. Specifically, the research work of this paper includes the following several parts:
(1) first of all, through the research of the development status of train safety monitoring system at home and abroad, pointed out the main problems of the monitoring network. To solve these problems, we put forward a new network architecture with Ethernet and fieldbus network technology, and the network structure, monitoring equipment, data flow, communication protocol data, analysis and storage process were analyzed, meet a series of requirements for city rail train safety monitoring network is put forward in the new era.
(2) second, according to the data storage and management of safety monitoring system of city rail train, using the relational database, the form structure of data storage system is studied. The design of database design code stored within the system data, reduce the data redundancy, save data storage space, improves the data the utilization rate of the sharing rate and query efficiency, but also lays a foundation for the development of software management platform system.
(3) once again, this paper uses the idea of modular design, the design of software management platform of city rail train safety monitoring system. The platform to complete the user management system, equipment management system, real-time monitoring equipment, historical data query, alarm information query, data report generation and fault analysis of a series of functions, provide a friendly management interface for system management, to improve the efficiency of the management staff, have important significance to protect the safety of train operation.
