| With the rapid development of Beijing Urban Railway Transit, the traditional maintenance system can not adapt to the current situation any more. The application of computer and network has provided an effective method to solve analogic problem by improving working efficiency and sorting all kinds of useful information for the sake of better maintenance and management. Through studying and analyzing the the background of oversea relating application system, this thesis discusses the MIS development of Beijing urban railway maintenance, linked to a subject on Beijing mass transit.Firstly, according to the theory of software engineering, the function of the system has been designed from the practical work on railway maintenance, and then its sub-module has been subdivide, through the use of WebGIS technology. In the concrete process of data collection,Java language is used to manipulate Excel files by invoking package Jxl, also, design pattern is in use to function file upload, etc. These functions enable the working staff to have a better knowledge of the status of the railway, and they can guide the process of maintenance.Secondly, based upon the thorough study on the maintenance work of Beijing railway tansit line, this thesis has classified the statistical data and uses the relational database principle to establish the table and the database with some system interface for system updating and merging. Meanwhile, this thesis offers one model of the network frame of the system, which offers some possible solutions to the common problems.Finally, this thesis makes detailed analyses on the base of practical research and development to discuss the key technological issues, such as database connection, and it has also discussed the way of database pool to realize solutions to solve a quantity of question in heterogeneous source connected. |
