农业数据网格体系研究

    Architecture of agricultural data grid system

    • 摘要: 由于农业数据具有地理分布、异构和动态等特性,网络环境下农业数据的分发组织和高效能处理是一个非常复杂且具有挑战性的问题。该文设计了层次式的农业数据网格系统软件体系结构;研究了基于时空本体的农业元数据建模、农业数据空间聚类与映射、多系统信息协同和层次访问控制机制等关键技术;构建了农业数据网格节点应用环境。测试检验结果表明,所设计的农业数据网格体系具有良好的网络高性能传输能力。

       

      Abstract: High performance processing of agricultural data in the grid environment is a complex and difficult problem, mainly due to agricultural data geographic distribution, heterogeneity and variety. A multi-layered software architecture for agricultural data grid system was designed. Agricultural meta-data model based spatio-temporal ontology, spatial clustering and mapping for agricultural data, information cooperation, role-based access control were researched. The application environment of agricultural data grid node was constructed. The inspection experiment indicates that the agricultural data grid system provides high performance computation and communication capability.
