The Design And Implementation Of The Actual Train Graphs Information Management System

Train graph is the base of railway transportation management and the working plan of transportation department. Since 1960's, China has made many great achievements in the field of computer-made-base train graph. However, the information management of actual train graph is still in the lower level. At present, train actual data collected from monitor device fixed on locomotives can only be stored in the form of text owing to lack of special data management system. In order to make full use of these data in railway management department at all levels, it is essential to set up a new management information system of actual train graph.This thesis is mainly concerned about how to design and realize a new information management system of actual train graph. The thesis first analyses the Client/Server structure of this new system and puts forward the distribution mode of the system database, based on the new research result, the overall framework of system has been designed. What's more, the function modules have also been worked out to meet the functional needs of the system.The thesis also analyses the design plan of system database, including its security, transaction management and ADO data access technology. Finally, the thesis discusses some concrete techniques in drawing train graph, particularly focusing on the way of organizing data which are used to draw graphs. The designing of data exchange function has been discussed in the thesis.The new train actual graph information management system can provide some new ways to analyse and manage the train actual running data, and greatly improve the work efficiency of the railway management of different railway departments, such as locomotive and dispatch department.
