桥梁预警系统异构数据库分布式引擎模块设计

Design of Distributed Engine Module of Bridge Alarming System Heterogeneous Database

针对桥梁预警系统群体间协同工作对信息共享的需求,从群体协同工作与面向应用的集成角度对桥梁预警系统异构数据库的集成方式进行了研究。提出了包含用户界面、异构集成模块和存储层三部分的桥梁预警系统异构数据库集成模式。该异构数据库集成模型由桥梁结构表征方法,命令解析模块和数据综合模块组成。在异构数据集成的基础上,实现了预警系统群体间的信息共享,为群体协同工作提供了技术支撑。最后通过模拟管理群体向预警系统提出获取桥梁抗震评估请求对异构集成模块的可实现性进行了验证。

In order to support information sharing needs for groups cooperation in bridge Manning system, the integration mode of the bridge alarming system heterogeneous database was proposed based on collaborative work and integration of application oriented. The proposed mode includes user interface layer, integration module and storage layer. The heterogeneous database model is composed of bridge structure expression, command disintegration module and data comprehensive module. Based on heterogeneous database integration, information sharing among groups was achieved to provide technical support for groups＇collaborative work. By a simulation process of management group＇ s request for bridge seismic evaluation from alarming system, the feasibility of the distributed engine was validated finally.
