【摘要】 车辆监控系统是集电子技术、通信技术和数据库技术在交通管理领域广泛应用而产生的一个崭新的领域。本设计利用现有的GPRS/GPS/GIS技术,针对铁路大型养路车设计出一个适用于08-32机型养路车的在线监控系统。它从铁路提速的实际情况出发,综合考虑了人、车、路等方面的因素,为铁路维修质量的提高和工作人员的操作方便提出了一系列解决方案,大大完善了大型养路车数据处理的功能,增强了人机的交互能力。本文首先对GPS、GPRS和GIS的基本理论进行了研究,并且对其在国内外的应用和现状进行了分析,然后将技术结合运用到系统设计中,并且提出了一个基于GPS/GPRS/GIS的养路车监控系统的设计方案。该监控系统是由下位机的车载终端系统、通讯服务器系统和上位机的监控终端系统三大部分组成,下位机负责数据采集;上位机负责数据显示、数据分析和数据处理;服务器负责连接上下终端的数据传送。当养路车开始维修作业时,车载终端的数据将经由通信服务器传达给监控终端,用户只需通过计算机的监控界面就能全面地了解维修当中的问题、全局地掌握铁路修复的质量。当机车遭遇抢劫、盗窃等情况时,车载终端将会及时向监控终端发出报警信号,通过该监控系统,用户可以及时地了解到目标机车的位置、速度、方向等相关信息。在此基础上,论文作者还针对上位机监控终端出现的软件安装维护问题,给出了不同用户不同模式的解决方案,对于非专业用户采用了C/S+B/S混合模式,该模式有效地提升了系统的维护性能,在实际运用中取得了较好的结果。基于GPS/GPRS/GIS的铁路养路车监控系统在铁路运输的安全性、可靠性方面有一定的实用价值,并且为保障维修质量、加强养路车管理、机车防盗、防抢等方面提出了一系列解决措施。此系统通过实际测试,其结果达到了预期的设计效果。更多还原

【Abstract】 ITS(intelligent traffic systems)is a new technology field that comes into being ,as soon as more electronic technology,communication technology and database technology were applied in traffic control .The design aim at railway maintaining-train ,using GPS/GPRS/GIS technology ,work out a Monitoring system that applies to 08-32 model Maintenance train .The design start from the actual situation of the train’s speedup to think the complication carefully about human ,trains and roads. Then it comes up with many situations in order to strengthen the quality of the railway’s Maintenance.In order to put theory into practice, the author researches many theories and applications of ITS and Monitoring system, and word out a detail design project . The system is consisted of train terminal system, supervising terminal system and communication server system .When the maintenance train work, the data is sending to the monitoring center by the communication service. While the maintenance train is hijacked, the monitoring system can send the help signal to the supervising center. According to the help signal, users can dispose the situation on time. In addition to these the author draw out a new solution based on software technology to improve the performance of the monitoring system .The monitoring system of railway maintenance train which is based on the GPS ,GPRS and GIS technology can produces a method to enhance the maintenance-train’s management and the ability of maintenance-train’s safe . The system has experienced practical test and achieve expectant result.更多还原
