Design And Implementation Of Large Screen Visualization System Based On Adaptive Vector Graphics Rendering Technology

With the development of data of large screen display technology, large enterprises in the planning, construction, operation, maintenance, marketing, human resources,financial, material and other business full range monitoring and analysis needs have become increasingly prominent, in order to achieve the business activities of enterprises of consolidated supervision. Therefore need to provide an easy and intuitive large screen display application and support for large screen, desktop and mobile applications, such as a variety of carriers, the carrier of rich large screen display show and desktop query,drilling analysis, to meet the national grid company headquarters, provincial and municipal levels a total of 287 block operation construction of large screen monitor.Through the analysis of customer needs, to understand the difficulty of the construction of the big screen is the need to support 287 pieces of different resolution screen splicing, need to provide a "design, and more use of large screen display system.Therefore, system adopts the technology selection based on vector graphics rendering,can be arbitrary zoom rendering as dot matrix graphics rendering. System uses the C / S architecture construction, the breakdown structure for a client, a server and a data service three sub systems, by drawing a vector, vector analysis and image stitching,highlighting the large screen rendering flexibility and resolution adaptive. Among them,the client uses C# development language construction, to meet the drawing fine operational requirements, the server is considered across heterogeneous systems access convenience, use java language to build, through the socket and client communication;in order to satisfy the different third party data sources of data access by independent outside data acquisition services, using java as a development language. In the image mosaic, the x86 and distributed rendering and image stitching technology to replace traditional centralized image mosaic device, in order to meet the resolution of the large screen splicing fast loading and reduce the investment cost of the hardware requirements. The final form contains a designer, player, controller, data acquisition as the main function of large screen display system.Through a series of tests on the system, the results prove that the realization of functions to meet the requirements, the availability of the system is verified. The vector drawing technology of large screen display system with the realization of a multiple fastadaptability design, the distributed image acquisition and rendering architecture can quickly build and expand and can better satisfy the mass of large screen splicing construction demand.
