Scheme Design Of The Power Supply Fixed Equipment Maintenance Information System

Recent years, with the progress of Passenger Dedicated Line's (PDL) construction, the length of PDL has been increased continuously; the importance and workload of fixed equipment maintenance in power supply system have been increased at the same time. It has become an important topic to study the power supply fixed equipment maintenance information system.Firstly, a simple introduction of PDL's maintenance management mode and the current status application in informationization is given in this paper. Considering the development trend of PDL's informationization in power supply fixed equipment management, a conclusion is given out that it is necessary to study a management information system for PDL's power supply fixed equipment maintenance.Secondly, through the research from the PDL's management departments, the analysis of demands, key business progress and data flow progress are completed. Considering the specific business targets, the overall design of the power supply fixed equipment maintenance information system is completed, including the whole architecture, the network structure, the application function modules and the information interfaces of the system.Thirdly, the design of the system refers to the principles and methods of developing a management information system and the method of combining the structure-design and object-oriented design is chosen in the paper. The solution of the system is focused on the advantages and disadvantages between Client/Server mode and Browser/Server mode as an emphasis. The mode combined C/S and B/S is chosen because of its high security, strong interaction and large amount of data requirement.Finally, the overall technology scheme of the system is put forward in this paper. The realization scheme of the software in C/S mode is give out considering the current status. At last, the login interface, the main interface and the interface of equipment management are realized and some application functions are also realized in the equipment management module.
