基于网格的桥梁远程结构状态评估系统研究*

利用网格技术基于开放式架构、通用技术规范以及标准中间件技术支持等优点，把分布的结构状态评估资源整合为网格服务，并在此基础上进行管理和调度，构建了基于网格的桥梁远程状态评估系统。设计了基于语义Web服务的网格服务模型来规范化服务的建模；结合Globus Toolkit 4（GT4）中间件,开发了网格服务管理模块，支持服务注册、搜索等功能；构建了基于agent技术的网格任务管理模块，支持结构状态评估任务的分解、分配、调度等功能。以洞庭湖大桥结构健康监测为背景，建立了应用原型。实践表明：系统能有效支持结构健康监

Research on remote structural-state-evaluation system for bridge based on grid

Taking advantage of the grid technique in open framework, general criterion, and standard middleware technology and so on, this paper proposed remote structural-state-evaluation system for bridge based grid, in which the distributing resources of structural state evaluation were defined as grid services, and under the management and control to evaluate the status of bridge.It designed grid service model based semantic Web to support formal modeling of grid service. By integrating Globus Toolkit 4 (GT4) middleware, also developed grid service manage module (GSMM) to provide functions for registry, discovery and so on. Furthermore, developed grid task manage module (GTMM) based agent technique to performs structural-state-evaluation task disassembling, scheduling and so on. Taking structural health monitoring for the Dongting Lake Bridge as application background, developed a prototype system. Practice shows that the system is able to offer effective way to apply the structural health monitoring.
