The Design And Implementation Of Prophase Management System In Power Supply Companies

The preliminary planning and management of power supply companies’ projects is the construction foundation for the development of the power industry.With the continuous improvement of power construction,the implementation of power engineering is becoming more and more difficult.At present,we are faced with the problems of low work efficiency,nonstandard pre-project planning and large budget.Therefore,planning project information in the pre-project stage can effectively help the project to carry out pre-planning and management control.Aiming at the problem of project prophase management in power industry,this paper firstly analyzes the research background of system design and the research status at home and abroad,and expounds the research significance of the system design.Then,the research objectives and overall requirements of the system are analyzed,the design requirements of each module of the system are determined and described by use case diagram,and the overall architecture,network structure,module function and data model of the system are completed.ASP.NET platform is used to implement the pre-project management system,and the implementation process of each functional module is described separately.Based on MVC design pattern,the system architecture is designed hierarchically,and scientific and information management methods are adopted to improve the pre-project work management.Finally,black box testing is carried out on the system,and Load Runner is used to describe the system performance testing process.The result analysis shows that the design meets the system performance requirements.The specific research contents and results are as follows:(1)In the analysis of system requirements,the method of data modeling is adopted.Firstly,the system requirements and development objectives are summarized.Secondly,the system project model is built by UML.The system requirements are described from the system development objectives,requirements overview,functional requirements and performance requirements respectively.Finally,the choice of ASP.NET development platform is determined.(2)In the detailed design of the system,the system architecture design and the system network topology structure design are carried out first,then the system function structure design such as system management,project basic data management,project plan management,approval management,project fund management and project file management are respectively completed,and finally the system database design is carried out.(3)In the realization of system functions,the realization process of the system is described by using class diagram and sequence diagram.The function realization methods of system management module,project basic data management module,project plan management module,approval management module,project fund management module and project file management module are introduced respectively,and the corresponding function realization test interface is displayed.(4)In the system test and analysis,LoadRunner software is used to record the test script to describe the system performance test process.The performance test shows that it meets the system performance requirements.The actual operation shows that the system can effectively improve the management level and methods in the early stage of the project,solve the problems of chaotic management system and backward management methods in the early stage of the project,and ensure the smooth progress of the preliminary work of the project.
