Abstract

This invention discloses a method and system for health monitoring of precast concrete beams based on distributed optical fiber sensing, belonging to the field of intelligent monitoring technology. For a target building, the method determines the concrete beam structure and reconstructs it into a risk transmission network. It initializes the front-end deployed optical fiber sensor array, detects and determines the optical signal, introduces a signal encoder for optical signal encoding and encapsulation, determines lightweight structural data, transmits it back, and triggers a health assessment module to perform assessment, judgment, and health decision-making, thereby determining the structural health status of the concrete beam. This invention addresses the technical problems of low scene adaptability and high analysis complexity in existing technologies, leading to poor monitoring results. It achieves highly adaptable monitoring deployment, effectively balancing monitoring processing efficiency and accuracy.
