The Design And Realization Of Power Distribution Management Information System On The Qingzang Railway

This paper is based on the management information system and the power distribution management for the QingZang railway. According to the current use of power-distribution management system, a research on the power distribution management information system for the QingZang railway is given in this paper and the design and realization are accomlished.Firstly, a simple introduction of the theory of the management information system and its development is given in this paper. The railway managing departments are tending to use more and more management information system to prove the working efficiency in our country. And the QingZang railway lies on the altiplano. Thus, it is hard to live along the railway line. So it is very necessary to manage the power distribution using the information system. Secondly, the demands of the management information system on the power distribution from the QingZang railway managing department are focused in this paper and at the same time the analyses of the customer demands are given out. Based on the above, a whole solving scheme and the design of the power distribution management information system, including the principles it should obey during the development process and the structure of the system are put forward in this paper. This paper also reveals the function models that should be realized in the system.The design of the system refers to the principles of developing a management information system and the method of combining the structure-design and object-oriented design is put forward in this paper. The design process of the system is established on the idea of the evolutional model and the spiral model. Finally, this paper ends with the detail design and implementation of the power distribution management information system for QingZang railway. The analysis of the technical design scheme and the choice of application platform are especially discussed in this paper. Finally, the function models are realized by programming, such as the power equipments management, power lines management and the paragraph management models.The system software structure is based on the client/middle level/sever three...
