【摘要】 开发长途光缆网络集中监管系统对于光缆网络实施集中式维护管理，提高管理效率和维护质量具有重要意义。本文建立了用于即时Web-OLAP的ODS模式，提出了基于Push／Pull模式的光缆故障实时告警技术，解决了光缆网络拓扑图的实现和优化问题，实现了三层体系结构的监管系统集成。本文的研究成果得到了实际应用。 第一章，给出了课题的研究背景和意义，介绍了监管系统相关技术的研究现状，分析了开发监管系统面临的一些问题，阐述了本文的研究内容与总体结构。 第二章，在对原有系统模式分析和DB、ODS、DW三种模式分析比较的基础上，采用了“自底向上”为主的技术路线建立ODS模式，研究了ODS模式建立的关键技术问题，建立了基于ODS的即时Web-OLAP的体系结构。 第三章，给出了实时告警的Push／Pull模式，设计了告警数据文件接口、基于映射的告警点定位新算法和告警图标网络拓扑图上定位算法，给出了基于Windows Socket进行网络应用开发的原理，采用基于CSocket的Push技术来实现告警事件的推送，利用传统的基于Http的Pull技术来实现告警页面的拉取。 第四章，对传统的利用MapXtreme平台实现WebGIS的方法进行改进，提出了基于MapX的WebGIS实现模型，给出了防障动态图标在光缆网络拓扑图上的定位算法，设计了基于事件状态位和图标状态位的快速更新图标方法，解决了网络拓扑图显示数据和数据库数据以及各客户端显示数据的一致性问题。 第五章，从系统集成的角度出发，分析了监管系统的网络组成以及软件体系结构和功能；结合工程应用，给出了系统的应用实例。 最后，对本文的研究工作进行总结与展望。更多还原

【Abstract】 Developing the COS(concentratedly overseeing system) of LFON(long-distance fiber optic network) is very important for concentratedly maintaining and managing the LFON. it can greatly improve the efficiency of management and the quality of maintenance. This dissertation constructs the ODS pattern for the Web-OLAP, presents the realtime alarm technologies of fiber optic breakdown based on Push/Pull pattern, solves the realization and optimization problems for the topological graph of fiber optic network, realizes the system integration among the three layer architecture patterns. The research results have been applied to practice.In chaper 1, the research background and significance of the subject are introduced. Then the current research state of its relative technologies is presented and some faced problems during the development are analyzed. Finally, the research content and main framework of this dissertation are described briefly.In chapter 2, based on the analysis of the original systems and the comparison among the DB, ODS and DW three patterns, the "from bottom to top" technology route is adopted to build up the ODS pattern. Then the key technology problems of the building process are studied. At last the Web-OLAP system architecture on the basis of ODS is established.In chapter 3, the Push/Pull pattern is gived out for the system realtime alarm. And the file interface of the alarm data, the algorithm of alarm position based on mapping and the algorithm of alarm icon position on the topological graph are designed. After explaining the principle of network software development using the Windows Socket, the Push technology based on CSocket is adopted to push alarm event and the Pull technology based on Http to pull the alarm page.In chapter 4, according to the traditional method using the MapXtreme platform to realize the WebGIS, the new WebGIS realization model based on MapX is put forward. Then the algorithm of defensive icon position on the topological graph and the icon refresh method based on event state and icon state are designed. Lastly, thedata consistency problems of the new model are presented and solved.In chapter 5, from the point of system integration, the integrating network, software structure and software capability of the COS are analyzed. And then the system examples are introduced on the engineering applications.In chapter 6, all achievements of this dissertation are summarized and the prospect of the research is given.更多还原
