J2ee-based Rail Freight Traffic Information System

The statistic work of wagon flow is necessary part in Railway Freight precise Statistic, it plays a very important role in the statistic accuracy of the freight ton-kilometer finished by administration, and it can reflect truly the status of input and output wagon flow on every boundary point. Along with the continuous development of information and network technology, the languages, such as ASP/ASP.Net,JSP,PHP, provide powerful technical support for building enterprise information platform. The database software such as Oracle,Sybase etc, provide technical guarantee for data exchange. J2EE lightweight framework combination is free and high efficient, it's the first selection in the development of middle-small enterprise WEB application system.Railway electronic consist system can provide with more accurate data for wagon flow statistics. The wagon flow information system adopt the railway electronic consist information. According to the result of path calculating, the work of statistic summary in wagon flow information figure is accomplished and the indirect wagon flow information is filtered. Month statistic report is created, the detail and summary data about wagon flow is sent to the railway ministry statistic center. The layered structure is applied in the system. It includes DAO layer, data persistence layer, service layer, control layer and view layer. The system presents with precise architecture, easy modification, quickly querying and accurate data.The real direction and changing situation of wagon flow is reflected from every angle. The accurate wagon flow statistic materials can be provided. Along with the implementation of the project, it can be grasped integrally in the whole railwaiy administration the detailed information of wagon flow. Through the research of the project, the means of wagon flow monitoring will have a leap forword, and statistical data quality will be improved.With the implementation of the project scheme, the level of informatization of wagon flow statistics will be lifted, the work load of the statisticians will be allivated, the accuracy and betimes character of statistic data will be enhanced, and amount of information of wagon flow statistic will be abundant. The wagon flow information dynamic management will be relized, the communication between the railway administration manager and the metrical operator will be convenient.The wagon flow statistic work will be finished more perfectly.Since the system putting into trail, the information of the whole wagon flow and the indirect wagon flow is provided, and it plays an important role in the work of wagon flow adjustment and wagon flow statistic analysis, especially it provides detail wagon flow information of TAI-JIAO line and HOU-YUE line transportation volume. To a certain degree, the betimes and accuracy of freight report form making is essured. And accurate indireat wagon flow information is provided for the task of increase transport and revenue and energy saving and lower consumption.
