【摘要】：随着轨道交通技术的进步和对城市快捷交通、绿色环保出行方式的追求,拥有环境友好、运载量大、便捷稳定和智能化水平高等优点的现代有轨电车逐步取代了传统有轨电车而在各大城市兴起,作为一种新型的轨道交通模式,现代有轨电车拥有电车调度指挥系统、智能旅客跟踪系统及信号机自动感应系统等智能化模块。要使上面各智能模块可以有效稳定的运行,也为了给乘客提供更加舒适安全人性化的乘坐体验,我们需要为现代有轨电车系统提供高精度、稳定、可靠的实时定位列车信息。列车监视系统是有轨电车智能交通系统中重要的一环,其关键在于要精准的掌握列车当前位置及状态信息,为了较好的实现这一目的,本文系统尝试结合Java编程软件、SQLServer数据库技术、现代通讯技术实现列车定位技术、全球卫星定位系统、地理信息系统来予以综合实现,最终使得监测者能够实时监控车路状态,极大提高运输效率,确保行车安全可靠。本文的研究内容重点在于如何快速准确地实时监控列车,并将监控结果显示在PC终端,整个流程实现了四块结构的整合：(1)列监系统将GPS/北斗导航、FRID应答器系统得到的位置信息运用相应算法加以修正；(2)车载硬件通过Zigbee模块将信息传递给列监平台,涉及到TCP/IP通讯模式及串口通讯模式的具体研发；(3)获取转辙机、信号机、股道信息是否占用等信息,并将列车信息、转辙机、信号机等状态信息传入列车监视系统系统并准确显示,保证上下游设备通讯状态的良好稳定。(4)列监平台将信息完整准确显示,系统采用Java面向对象的编程理念,及多线程技术,三层架构支撑的编辑模式,可以让系统拥有更好的可移植性,不同领域的部件加上公用的方法库,以及流畅无耦合性的接口让平台运用于其他运输行业也会方便简捷。
[Abstract]:With the development of rail transit technology and the pursuit of fast urban transportation and green travel mode, it has a friendly environment and a large amount of transportation. Modern trams, which have the advantages of convenience, stability and intelligence, have gradually replaced the traditional trams and become popular in major cities. As a new mode of rail transit, modern trams have a tram dispatching command system. Intelligent passenger tracking system and automatic sensing system, etc. In order to make the above intelligent modules run effectively and stably, and to provide passengers with a more comfortable, safe and humane ride experience, We need to provide high-precision, stable and reliable real-time positioning train information for modern tram systems. Train monitoring system is an important part of the intelligent transportation system of tram. The key is to accurately grasp the current position and status information of the train. In order to achieve this purpose, this paper attempts to combine Java programming software with SQL Server database technology and modern communication technology to realize train positioning technology. The global positioning system (GPS) and the geographic information system (GIS) are integrated to enable the monitor to monitor the road status in real time and greatly improve the transportation efficiency. This paper focuses on how to monitor the train quickly and accurately in real time and display the monitoring results in PC terminal. The whole process has realized the integration of four structures: 1) the system of column monitoring, which uses the corresponding algorithm to modify the position information obtained by GPS / Beidou navigation / FRID transponder system) the on-board hardware transfers the information to the train monitoring platform through the Zigbee module. The research and development of TCP/IP communication mode and serial communication mode are related to the acquisition of information such as switch machine, signal machine, track information, etc., and the train information, switch machine, etc. The state information, such as signal machine, is introduced into the train monitoring system and displayed accurately, which ensures the good and stable communication status of the upstream and downstream equipment. The platform displays the information completely and accurately. The system adopts the object-oriented programming concept of Java and multi-thread technology. The editing mode supported by the three-tier architecture enables the system to have better portability, with components in different areas plus a common library of methods, and a smooth, uncoupled interface that makes the platform easier and easier to use in other transport industries.
