Design And Implementation Of Cost Management System For Sichuan Power Transmission And Transformation Project Based On J2EE

In order to meet the increasing power demand of residents and enterprises,a provincial power company needs to start construction of multiple power transmission and transformation projects every year,and also maintain the existing power transmission and transformation infrastructure.However,the power company itself does not have the construction capacity and needs to pass The bidding method outsources the power transmission and transformation project to a professional construction company.The cost management department of the power company needs to estimate the cost of the entire project and control the progress.However,the current cost management department uses Excel tables or paper to record,and its efficiency is very low.In order to change the existing power transmission and transformation project cost management mode,cost management The department decided to promote the informatization construction of cost management business.The main purpose of this paper is to develop a cost management system for power transmission and transformation projects.According to the theory of software engineering,it can be divided into requirements analysis,system design,system implementation and testing.This article first investigates the project management of power transmission and transformation projects of a provincial power company,and visits the company’s leaders and employees of the cost management department to determine the functions that the power transmission and transformation project cost management system should have;secondly,according to the system requirements,gather together The characteristics of the system,the developers designed the basic project information,project cost management,project schedule management,project material management,and system management modules;finally,the developers coded and tested the system function modules according to demand analysis and system design content.Prepare for the system to go live.Developers designed project bidding management,project cost management,project schedule management,project material management,system management and other functions according to user needs,and then designed and coded these functions.This article is based on the J2 EE platform and has carried out an in-depth development of the cost management of power transmission and transformation projects.The data storage platform used is the SQL Server 2012 database,and the third-party gateway technology is used to realize the bid-winning notification function and the progress alarm function.Developers use a large number of functional plug-ins and design patterns in the coding process,which not only improves the development efficiency,but also increases the stability of the system.At present,the cost management system for power transmission and transformation projects has been deployed to the power company,which not only reduces the workload of the cost management department,but also improves the internal management level of the power company,which has been widely praised by users.
