网络环境下桥梁协同预警系统设计与集成技术

Design and Integration Technology of Coordinated Early Warming System for Bridges under Network Environment

桥梁健康监测系统存在的问题是不支持群体间的协同工作,这一缺陷致不能反映桥梁安全受控的本质,障碍了桥梁健康监测系统的进一步发展。该文介绍了在网络环境下,桥梁协同预警系统设计与集成技术。桥梁预警系统从支持群体的协同工作为目标,首先采用群体内应用C/S结构,群体间应用B/S结构的分布式设计方法建立了网络环境下桥梁与预警系统的体系结构,分析了组成预警系统的各个层次的主要功能,通过对预警系统的业务流程进行分析,认为系统集成的关键技术是接口设计。最后以损伤识别后一个连续梁桥在设计地震下的抗震性能评估为例,对系统的可行性进行了验证。

The existing problem in the bridge health monitoring system is not to support the coordination work among the bridge group.This fault results in not able to reflect the security control of bridge and to obstruct the further development of the bridge health monitoring system.The article introduces the design and integration technology of coordinated early warming system for the bridge under the network environment.As the objective of supporting the coordination of group,the C/S structure is applied within the group for the early warming system of bridge.The application of B/S structural distribution design method among the groups sets up the system structure of bridge and early warming system under the network environment.The article analyzes the main functions to compose each level of the early warming system,and considers that the key technology of system integration is the interface design after the analysis of the operation flow of early warming system.The feasibility of the system is validated according to the evaluation of seismic performance of a continuous beam bridge under the design earthquake after the damage identification.
