【中文摘要】 地质信息在煤矿安全生产过程中扮演着基础性的角色。为应对煤矿地质信息管理和煤矿生产决策的需要,论文以地质信息共享为主线,研究了基于Web Services架构下的地质信息集成模型,构建了异源、异构、异库的复杂地质信息集成平台。论文首先分析了地质信息的特点,以及煤矿信息集成管理的需求,重点研究了煤矿地质信息集成的相关理论、方法和关键技术。针对煤矿地质信息的多源性、信息表达格式多样性,以及信息的空间分布性,论文将本体匹配、元数据集成理论、框架集成理论和开源技术相结合,实现了Web Services架构下的地质信息集成平台。论文取得的主要成果有:(1)论文分析了地质信息具有的结构性和非结构性数据共存特性,研究了元数据的集成模式,提出了煤矿地质信息的结构化集成管理模型。利用提取地质信息的关键属性,构建结构化的索引/元数据库,采用关联、依赖模式和本体匹配的综合算法,构建了地质信息的主题查询模型;(2)论文针对煤矿地质信息产生的分散性,用户的分散性,以及地质信息在煤矿企业决策过程中的流向,设计了索引/元数据集中,源数据分散储存的地质信息集成共享平台;(3)论文开展了元数据的语义一致性研究,提出建立煤...更多矿地质元数据的原则,设计了基于描述型元数据、维护型元数据和应用型元数据类型的煤矿地质信息元数据应用实例;(4)论文以元数据集成理论的语义一致性映射技术,解决矢量数据的语义不一致,可对不同结构化的空间数据实现动态提取与转换;(5)论文采用开源组件及MapServ.C等动态连接库,以PHP和Python脚本语言构建了Web Services架构下的地质信息平台模型,实现了符合煤矿规范和图例的信息共享系统,(6)论文采用了Ajax的XMLHttpRequest异步通讯技术,丰富了Web用户的交互功能,实现矢量地图的漫游、缩放与定制;该论文有图25幅,表4个,参考文献97篇。  还原

L9x } W&~u0【英文摘要】 Geological information plays a fundamental role in coal mine production and safety. In response to mine geological information management and decision-making needs of coal mine production, with the main line of geological information sharing, thesis researches the geological information integration model on Web Services framework, and constructs an integration platform for complex geological information of different sources, heterogeneous and different databases.At first, thesis analyses the characteristics of geological information, as well as the needs of coal mine information integrated management, it researches taking focus on the related theories, methods and key technologies for the integration of mine geological information. Considering about the multi-sources, diversity of expression format and the spatial distribution nature of mine geological information, thesis combines open-source technology with ontology matching theory, metadata integration theory and framework integratio...更多n theory, and has realized the geological information integration platform on Web Services framework.Main achievements include:(1)Thesis analyses the coexistence characteristics of structured and unstructured data geological information has, studies the integration model of meta-data, it also constructs a structured integrated management model for mine geological information. Through extracting key attributes of geological information, thesis has established Index / meta-database, using association, dependence model and ontology matching algorithms, thesis has built a theme query model of geological information.(2)To the dispersion of geological information and users, as well as the flowing direction of geological information on decision-making process of coal mine enterprises, thesis designs integration & sharing platform of geological information, the storage of index/ metadata is concentrated and source data is disperse.(3)Thesis studies the semantic consistency of meta-data, proposes the principles for establishing coal mine geological metadata, designs application example of coal mine geological information metadata based on the description metadata, maintenance metadata and application metadata types.(4)By the semantic consistency mapping technology of metadata integration theories, thesis has resolved the semantic inconsistencies of vector data, the dynamic extraction and conversion of diverse structured spatial data can be achieved. (5)Using open source components and dynamic link library such as MapServ.C, thesis has built a geological information platform model on Web Services framework by PHP and Python scripting language, and has realized the coal mine information-sharing system according with the criterions of coal mines and legend requirements.(6)Thesis adopts the XML Http Request asynchronous communication technology of Ajax, enriches the interactive function for Web users, realizes the panning, zooming in/out and customizing of vector map.  还原水利论文*d]x/M%^|#I
