Research And Development Of The Expressway Toll Collection Network System And Distributed Database

In this papcr,I systemically introduce the design and software control iml)lernentatiOn of expressway toll collection system .Meanwhule,I discuss the popular distributed calculation model and the implementation of distributed databse system currently. There are two ways to implement distributed database: (1)distributed transactions; (2) Replication. This system is a basic applied field in intelligent Transportation System .The main feature lies in its highly integrated system. By utilizing advanced technologies of communication,computer scicnce,auto-control and video frequency monitoring, we achieve scientifically to manage expressway network toll collection . expressway network toll collection system uses Client/Server structuresWindows NT + Microsoft SQL Server are applied as DBMS(Database Management System),Besiig on those ,Clicnt terminal takeover toll collection control data collcction~ real-time rnonitoring~. data analysis and data statistic and so on .In my paper, I discuss the application programs on Client terminal and specify my work in detail.
