【摘要】：隨著數(shù)據(jù)大屏展示技術(shù)的發(fā)展,大型企業(yè)在規(guī)劃、建設(shè)、運(yùn)行、檢修、營銷、人資、財(cái)務(wù)、物資等業(yè)務(wù)全方位監(jiān)測分析需求日益突出,從而實(shí)現(xiàn)對(duì)企業(yè)的經(jīng)營活動(dòng)進(jìn)行綜合監(jiān)管。因此需要提供直觀方便的大屏展示應(yīng)用,支持大屏、桌面、移動(dòng)應(yīng)用等多種載體,通過這些載體進(jìn)行豐富的大屏展示展現(xiàn)以及桌面查詢、鉆取分析,滿足國家電網(wǎng)公司總部、省、市三級(jí)共287塊運(yùn)營監(jiān)控大屏的建設(shè)。通過對(duì)客戶需求的分析,了解到本次大屏建設(shè)的難點(diǎn)在于需要支撐287塊不同分辨率的屏幕拼接,需要提供一套“一次設(shè)計(jì)、多地使用”的大屏展示系統(tǒng)。因此,系統(tǒng)采用基于過可任意縮放、點(diǎn)陣?yán)L制的矢量圖形繪制技術(shù)作為圖形繪制作為技術(shù)選型。系統(tǒng)采用C/S架構(gòu)構(gòu)建,將架構(gòu)細(xì)分為客戶端、服務(wù)端和數(shù)據(jù)服務(wù)三個(gè)子系統(tǒng),通過矢量繪制、矢量解析和圖像拼接的方式,適應(yīng)大屏畫面繪制的靈活性和分辨率適應(yīng)性要求。其中,客戶端采用C#開發(fā)語言構(gòu)建,以滿足圖形繪制的精細(xì)操作需求;服務(wù)端考慮異構(gòu)系統(tǒng)接入的便利性,選用JAVA語言構(gòu)建,通過Socket與客戶端進(jìn)行通信;為滿足多種第三方數(shù)據(jù)源的數(shù)據(jù)接入需求,采用獨(dú)立外掛式服務(wù)方式構(gòu)建數(shù)據(jù)采集器。在圖像拼接時(shí),采用X86服務(wù)分布式繪制與圖像拼接技術(shù)替代傳統(tǒng)集中式圖像拼接器,以滿足大分辨率的拼接畫面快速和降低硬件投資成本的要求。最終形成包含設(shè)計(jì)器、播放器、控制器、數(shù)據(jù)采集器為主體功能的大屏展示系統(tǒng)。通過對(duì)本系統(tǒng)的一系列測試,結(jié)果證明實(shí)現(xiàn)的功能符合要求,系統(tǒng)的可用性得到驗(yàn)證。采用矢量繪制技術(shù)的大屏展示系統(tǒng)具備實(shí)現(xiàn)一次設(shè)計(jì)多處適應(yīng)的快速能力,其分布式的圖像采集與繪制架構(gòu)能夠快速的構(gòu)建和擴(kuò)展,能較好滿足大規(guī)模拼接大屏建設(shè)需求。
[Abstract]:With the development of data display technology, large-scale enterprises in planning, construction, operation, maintenance, marketing, human capital, finance, materials and other business comprehensive monitoring and analysis needs are increasingly prominent. In order to achieve the business activities of enterprises to conduct comprehensive supervision. Therefore, we need to provide intuitive and convenient large screen display applications, support large screen, desktop, mobile applications and other carriers, through these carriers to display a wealth of large screen display and desktop query, drilling analysis, to meet the State Grid Corporation headquarters, Provincial, municipal, a total of 287 operation monitoring screen construction. Through the analysis of customer demand, we know that the difficulty of this large screen construction lies in the need to support 287 screen splicing with different resolution, and to provide a large screen display system with "one time design, multiple use". Therefore, the system adopts vector drawing technology based on arbitrary scaling and dot matrix rendering as the technology selection. The system is constructed with C / S architecture. The architecture is subdivided into three subsystems: client, server and data service. Through vector rendering, vector analysis and image splicing, the system adapts to the flexibility and resolution adaptability of large screen rendering. Among them, the client is constructed with C # development language to meet the need of fine operation of drawing, and the server takes into account the convenience of heterogeneous system access, chooses JAVA language to construct, and communicates with the client through Socket. In order to meet the data access requirements of various third party data sources, a data collector is constructed by using independent external service. In image mosaic, the traditional centralized image mosaic is replaced by X86 service distributed rendering and image mosaic technology, which can meet the requirements of fast stitching with large resolution and reducing the cost of hardware investment. Finally, a large screen display system with the main functions of designer, player, controller and data collector is formed. Through a series of tests on the system, the results show that the function of the system meets the requirements and the usability of the system is verified. The large screen display system using vector rendering technology has the ability to design multiple adaptations in a single time. Its distributed image acquisition and rendering architecture can be constructed and expanded quickly and can meet the needs of large screen construction.
