Design And Realization Of Graphical Tool For Operation Mode Management System Of Power Communication Network

Operation mode managemennt of power communication network is an effective means to improve the operation efficiency of communication network, in which rendering operation mode graphics is an important part. This paper uses Rich Internet Applications development mode based on the Flex technology to design and implement graphical tool of communication network operation management system. This graphical tool changes the traditional manual edit mode, improves the efficiency of the drawing and realizes the intelligent and informationalized mode management. Firstly the management situation of power communication network operation mode is introduced, the development of graphical tool and its application situation in electric power system is summarized in this paper. On the base of analyzing the shortcomings existing in development mode of present graphics tools, combing with the features of communication network operation mode management, the Rich Internet Applications development mode based on Flex is proposed. Then the requirements analysis and design on the graphical tool are made, including system outline, function requirements and system attribute requirements, the overall design of system, function module, entity structure and user interface design, data storage design and centralized management. Finally, each functional module of the graphical tool is implemented based on the Flex technology, including drawing, zoom, select and block operation of the entity, scaling and navigation of the view, storage, printing and export of the graphics file, the implementation of graphic tool and other interfaces. And an example is used to verify the practicability of this graphical tool.
