采用网络通信、数据库、GIS等技术构建一种分布式环卫中心车辆运输管理信息系统。系统采用GPRS网络、Internet网络实现了数据通信，利用功能强大SqlServer数据库管理系统实现了数据的存储、更新，通过MapX组件式GIS技术对地图进行操作、管理，实现了鹰眼窗口。提供了多窗口界面，方便了用户对系统的操作、管理，提出并实现了转发中心的设计思想，实现了多个车载、多个地磅与不同位置的分中心数据通信的分布式结构，提高了数据传输的稳定性、可靠性，为大规模车辆运输数据采集奠定了基础。本系统为环卫中心管理部门的规划、决策提供了强有力的技术支持。

Design of a Distributed Management Information System of Vehicle Transportation of Environment Sanitary Center

A distributed environment sanitary management information system is designed by the use of network, communication, database, GIS. The system makes use of GPRS, Internet to realize data communication, utilizes SqlServer, namely, a strong database management system to store, update data of the system, and uses MapX which is a com GIS technology to manipulate, manage the map, and to design eagle-eye map window. A mulit-window interface is given to provide the user a convenient method to operate the system. Moreover, a transmitting data center is presented to realize a distributed structure that transmits data from multi-vehicle-terminal, multi-platform-balance to multi-sub-center so that the stability and reliability of the system is improved, and lays a good foundation to collect lots of data of a large -scale vehicle transportation. In short, the system provides a powerful technique support for environment sanitary management center to work out plans and make a decision.
