【摘要】 传统的GIS／GPS车辆监控系统已经不能适应现代物流的信息化、网络化和社会化趋势，越来越迫切的需要和国际互联网技术(INTERNET)结合，以达到对物流企业优化资源配置、提高市场竞争力。因此GPS、GIS、与INTERNET等各项先进技术的融合形成了现在的网络GPS(WEBGPS)。网络GPS综合了INTERNET与GPS，GIS的优势与特色，取长补短，它解决了原来使用GPS／GIS车辆监控系统所无法克服的障碍。 本论文在分析了GIS技术，GPS技术，SMS技术以及INTERNET技术的基础上，从系统总体设计的角度阐述了网络GPS监控中心的设计及实现的全过程，完整地实现了定位数据的传输、电子地图的网络发布、移动车辆的监控及其运动轨迹的描绘，并由此构建了一个监控网站，供网络用户访问。在设计过程中，针对网络延迟较大，不利于监控显示的问题，提出了将移动车辆运动轨迹的描绘从服务器转移到客户端来完成的思想，并采取了相应的技术实现了这一思想。 虽然由于时间与精力有限，本次研究实现的WebGPS软件功能有限，但已经具备了一个网络GPS监控中心的基本功能。相信随着研究的继续深入，功能的进一步完善，此监控中心的使用将大大提高车辆的运营效益，增强运输业的竞争能力，具有显著的经济效益。更多还原

【Abstract】 Traditional Supervising and controlling system based on GIS/GPS has not been suit modem carrying trade, it needs information ,network and socialization. It needs more and more combine with Internet to optimize resource scheme and improve competition in market. So GPS, GIS, Internet and other advanced technologies are combined to form WebGPS now. WebGPS integrate each superority and trait from GPS, GIS and Internet, learn from others’s strong points to offset one’s weakness, solved the obstacle that Traditional Supervising and controlling system based on GIS/GPS can’t conquer.The thesis analysed the technology about GPS, GIS and Internet, and expatiated the whole process about the design and realization of the supervising and controlling center based on WebGPS. The thesis realized the transmission of GPS information, the issuance of electronic map in the internet, the supervising and controlling of vehicle and the discription of it’s track, and composed a network station to serve for network users. In the process of the design, because the delay of the internet is badly and infect the display fo the supervising and controlling process, we bring forward the idea that the track is described in client side not server side , and realized this idea using some certain technology.Because of the limitation of time and energy, the functions realized in this research are limit, but it’s enough to be the basical functions of a supervising and controlling center based on WebGPS. I think the research is continue, and the function are consummated, the use of this supervising and controlling center will improve the benefit of the vehicles and enhance the competility of carrying trade. It will benefit us greatly.更多还原
