大型桥梁结构智能健康监测系统集成技术研究

首先分析研究了桥梁健康监测系统的各个子系统的功能、特点、实现方法与硬软件系统,研究了完成桥梁健康监测任务对各个子系统协同工作的要求。提出了以LabW indows/LabVIEW为桥梁健康监测系统的核心软件,由它“指挥”、调用和驱动各个子系统的运行和数据的交互与通讯;以数据管理子系统的数据库作为桥梁健康监测系统的中心数据库,它不仅存储桥梁结构及其监测数据的全部信息,同时所有的数据交互均通过该数据库完成。建议采用B rower/Server系统模式将桥梁结构健康监测的各子系统相互结合,建立基于网络平台的开放式的实时在线智能健康监测系统。最后,为一座实际的三塔斜拉桥集成了一套健康监测系统。

A study on system integration technique of intelligent monitoring systems for soundness of long-span bridges

This paper analyzed all the subsystems in their functions,characteristics,implementations,and their hardware and software.A study was made on the requirement of concerted application of these subsystems for the soundness monitoring of long-span bridges.It was suggested that LabWindows/Lab VIEW is to be used as the main system to control the running of the subsystems and the interchanging of information among them.The database of a data menagement system is used as the central database,which stores not only the information of the bridge structure,but also the monitoring information.It was suggested to use Brower/Server system to connect all the subsystems,and an open,real time and online soundness monitoring system based on the network platform can be formed.Finally,a soundness monitoring system for a three-tower cable-stayed bridge was cited as an example.
