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.
