Abstract

To achieve timely and effective monitoring of the health status of bridge power cables, as well as to address the deficiencies in the existing monitoring system such as incomplete functional and state evaluation, we propose a multi-parameter state monitoring system based on fiber Bragg grating (FBG) sensing technology and microelectromechanical systems (MEMS) sensing technology. This system enables vibration, strain, temperature, and deformation measurements of both the bridge power cable and its expansion compensation device. In order to comprehensively evaluate the health status of the bridge power cable, we introduce a comprehensive fusion model for multi-state assessment. Furthermore, to enable real-time monitoring capabilities, we have developed a web-based monitoring system that can receive real-time sensor data and present it to users through an intuitive visual interface. Finally, by applying our proposed model to Zhoushan–Daishan Bridge in Zhoushan City as an example, we validate its feasibility and effectiveness in enhancing performance and practicality of bridge power cable monitoring systems.

桥梁电缆健康状态监测系统及多状态量融合评价研究

为实现对桥梁电力电缆健康状态的及时有效监测，并解决现有监测系统功能和状态评估不完整等不足，提出了一种基于光纤布拉格光栅（FBG）传感技术和微机电系统（MEMS）传感技术的多参数状态监测系统。该系统能够测量桥梁电力电缆及其膨胀补偿装置的振动、应变、温度和变形。为了对桥梁电力电缆的健康状况进行综合评估，提出了一种多状态综合融合评估模型。此外，为了实现实时监控功能，我们开发了一个基于网络的监控系统，可以接收实时传感器数据，并通过直观的视觉界面将其呈现给用户。最后，以舟山市舟山-岱山大桥为例，验证了该模型在提高桥梁电力电缆监测系统性能和实用性方面的可行性和有效性。
