The Design And Implementation Of HN Nuclear Power Construction Management System Base On Parallel Download

The system of Nuclear power construction management is a management mode and it is important means of nuclear power construction management in China,the computer is the modern management mode that it is the most important platform for the construction of nuclear power projectse The use of existing management mode of management,so as to realize the "everything rule-based was responsible for everything,how to use the concept of nuclear power management is very important through the construction of nuclear power project management practical significance for nuclear power construction safety management and orderly.The management of nuclear power construction projects in China is still in its infancy,and the application of enterprise level architecture construction management system is still very few.Therefore,how to make use of the existing computer technology level and change the traditional management mode has become the urgent task of modern nuclear power enterprise project construction management.Combining with the construction of nuclear power project management HN the traditional business process,under the environment of computer network,It is to carry out the design and development of NH nuclear power construction management system based on J2EE system architecture,the research the overall functional coverage of HN nuclear power construction process construction of nuclear power is a new milepost of tube.It is the main research target through the construction of HN nuclear power construction management system based on J2EE framework.From the business framework of the overall needs analysis and design,it needs establishing security management,construction management,progress management,quality management module composed of construction management system.Secondly,the system structure of the paper is divided into the presentation layer on the level of the system,logic layer,data access layer,each layer between can deal with different business logic which is improve system efficiency and reduce the coupling degree between the system.Third,design and development of the system interface using HTML and JS language interface,the system can send the actual user request to the business logic layer by encapsulating interface,business logic layer on the first user request analysis,and call the interface method and data layer interact,thus completing the system request the whole process of operation.Fourth,This system uses the parallel downloading algorithm of nuclear power construction related information file downloads,the algorithm can download files from the file at the position of nuclear power construction is selected by the user at any time,and when the download to the end position sequence,can not continue to download to download the Shi Gongwen nuclear power,at the same time the algorithm can stop at any time to download.The implementation of this algorithm reduces the waiting time of users downloading nuclear power construction related information files,and the algorithm does not affect other users to download the relevant information files of nuclear power construction in the same sequence,thus greatly improving the timing of the system.As the system requires more data,the system uses ORACLE11g as the data storage structure,and provides data backup function,so as to ensure the integrity and security of data.Finally,the system function test and performance test are carried out to verify the design and implementation of the system to meet the actual user needs of the enterprise.Through the practical application of the system shows that the construction of this system has good versatility,convenient operation system,it meets the existing business process,improve the system security and practicability,the system interface is to meet the construction schedule requirements of nuclear power project management friendly.The implementation of this system effectively improves the efficiency of project construction management,which improves the level of enterprise informatization and has a good market prospects.
