分布式网络化桥梁结构安全监测系统研究

提出以一个专家系统为分析方法,由三级网络结构组成的分布式网络化结构监测和健康分析系统的网络框架,适用于桥梁的主要结构状态监测及健康评估,为桥梁从定期检测向预测检修模式提供技术保障。该监测系统经过一年多的考验表明,光纤光栅的稳定性和耐久性满足桥梁结构长期健康监测的要求,为桥梁结构的健康诊断提供了依据。

Research on a Distributive Network System for the Safety Monitoring of Bridge Structure

The paper proposed the framework of distributive network system for structure monitoring and health analyzing,which based on expert systems as the main diagnosing resort,was composed of a tripe stage hierarchic structure and could be used for system state monitoring and health evaluating of the main structure of bridge and may serve as the important technical guarantor that change the planned overhaul to premonitory repair for bridges.The monitoring systems had withstood ordeal for more than one year proved that their durability and stability satisfied the need of health monitoring for bridge,and information could be provided for structural health diagnosis.
