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 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.
