【摘要】：隨著數(shù)字城市的發(fā)展，數(shù)字城市系統(tǒng)在許多方面都面臨嚴(yán)峻的挑戰(zhàn)。例如如何協(xié)調(diào)解決信息孤島問(wèn)題，大范圍三維場(chǎng)景瀏覽顯示問(wèn)題，服務(wù)范圍不均衡問(wèn)題，重復(fù)開(kāi)發(fā)問(wèn)題，服務(wù)資源相對(duì)匱乏問(wèn)題等。本文在分析數(shù)字城市面臨的諸多問(wèn)題的基礎(chǔ)上，試圖找出一條能夠解決上述問(wèn)題的途徑。首先，對(duì)數(shù)字城市的相關(guān)概念、數(shù)字城市的發(fā)展和數(shù)字城市開(kāi)發(fā)平臺(tái)等研究背景進(jìn)行了闡述，并對(duì)數(shù)字城市系統(tǒng)的功能、網(wǎng)絡(luò)結(jié)構(gòu)等進(jìn)行了設(shè)計(jì)；其次，對(duì)數(shù)字城市系統(tǒng)涉及到的緩存機(jī)制、內(nèi)存機(jī)制、Peer to Peer網(wǎng)絡(luò)模型和OpenAPI等關(guān)鍵技術(shù)進(jìn)行了研究；然后，基于ArcGIS Engine在.Net環(huán)境下對(duì)設(shè)計(jì)的數(shù)字城市系統(tǒng)平臺(tái)予以實(shí)現(xiàn)；最后，對(duì)研究?jī)?nèi)容進(jìn)行了總結(jié)，并指出數(shù)字城市系統(tǒng)有待進(jìn)行研究的技術(shù)。論文研究的主要內(nèi)容有：1.數(shù)字城市基礎(chǔ)地理信息空間數(shù)據(jù)和三維模型數(shù)據(jù)的磁盤(pán)緩存的創(chuàng)建以及三維數(shù)據(jù)緩存的內(nèi)存管理。2.數(shù)字城市系統(tǒng)的網(wǎng)絡(luò)拓?fù)浣Y(jié)構(gòu)的設(shè)計(jì)與實(shí)現(xiàn)3.磁盤(pán)緩存的傳輸與共享。4.數(shù)字城市系統(tǒng)平臺(tái)的功能、用戶(hù)界面和交互方式的設(shè)計(jì)與實(shí)現(xiàn)。5.數(shù)字城市系統(tǒng)的地理信息資源與互聯(lián)網(wǎng)資源的結(jié)合。論文的創(chuàng)新之處在于提出在三維數(shù)字城市系統(tǒng)平臺(tái)上根據(jù)數(shù)據(jù)類(lèi)型分別同時(shí)使用C/S結(jié)構(gòu)（客戶(hù)端—服務(wù)器結(jié)構(gòu)）和混合式P2P結(jié)構(gòu)（混合式對(duì)等網(wǎng)絡(luò)結(jié)構(gòu)）來(lái)有效管理數(shù)據(jù)流并同時(shí)均衡網(wǎng)絡(luò)載荷；側(cè)重對(duì)數(shù)字系統(tǒng)的用戶(hù)界面及交互方式的設(shè)計(jì)并結(jié)合第三方組件庫(kù)進(jìn)行系統(tǒng)平臺(tái)的美化，，增強(qiáng)用戶(hù)友好度；設(shè)計(jì)磁盤(pán)緩存的傳輸與共享并在對(duì)等網(wǎng)絡(luò)結(jié)構(gòu)的基礎(chǔ)上通過(guò).NET的遠(yuǎn)程通道技術(shù)并結(jié)合數(shù)據(jù)壓縮開(kāi)源庫(kù)予以實(shí)現(xiàn)；采用以O(shè)pen API為代表的互聯(lián)網(wǎng)資源與數(shù)字城市地理信息資源的結(jié)合有效解決數(shù)字城市系統(tǒng)在服務(wù)方面資源相對(duì)匱乏問(wèn)題。論文設(shè)計(jì)并實(shí)現(xiàn)的數(shù)字城市系統(tǒng)平臺(tái)經(jīng)過(guò)測(cè)試初步解決了當(dāng)前數(shù)字城市系統(tǒng)應(yīng)用所面臨的問(wèn)題，同時(shí)也存在許多不足，將在今后的研究中進(jìn)一步完善。
[Abstract]:With the development of digital city, digital city system is facing severe challenges in many aspects. For example, how to coordinate and solve the problem of information island, the problem of large scale 3D scene browsing and displaying, the problem of service scope imbalance, the problem of repeated development, the problem of relative scarcity of service resources, and so on. Based on the analysis of many problems faced by digital city, this paper tries to find a way to solve these problems. Firstly, the related concepts of digital city, the development of digital city and the research background of digital city development platform are expounded, and the function and network structure of digital city system are designed. The cache mechanism, memory mechanism, Peer to Peer network model and OpenAPI are studied. Then, the digital city system platform based on ArcGIS engine is implemented in .Net environment. This paper summarizes the research content and points out the technology to be studied in digital city system. The main content of the thesis is: 1. The creation of disk cache for digital city basic geographic information spatial data and 3D model data and the memory management of 3D data cache. The design and implementation of the network topology of digital city system. Disk cache transfer and sharing. 4. 4. Design and implementation of function, user interface and interactive mode of digital city system platform. 5. The combination of geographic information resources and Internet resources in digital city system. The innovation of this paper is that the C / S structure (client-server structure) and hybrid P2P structure (hybrid peer-to-peer network structure) are used simultaneously according to the data type on the 3D digital city system platform. Managing data flow and balancing network load at the same time; It emphasizes on the design of user interface and interaction mode of digital system and beautifies the system platform with the combination of third-party component library to enhance the user friendliness. The transmission and sharing of disk cache is designed and implemented through .NET remote channel technology and data compression open source library on the basis of peer-to-peer network structure. The combination of Internet resources represented by Open API and geographic information resources of digital city is used to solve the problem of relative shortage of service resources in digital city system. The digital city system platform designed and implemented in this paper has solved the problems in the application of the digital city system after testing, and at the same time, there are many shortcomings, which will be further improved in the future research.
