BRIDGE INTELLIGENT CABLE SYSTEM WITH BUILT-IN FIBER GRATING SENSOR
A bridge intelligent cable system with a built-in fiber grating sensor is provided, which is applied in a cable bearing structure such as a cable-stayed bridge, a suspension bridge, and an arch bridge. The system includes an anchor cup (1), a wire dividing plate (5), a connecting cylinder (4), a fiber grating sensor, and a cable body (11), in which the fiber grating sensor includes a fiber grating strain sensor (9) and a fiber grating temperature sensor (10), tail fibers of the fiber grating strain sensor (9) and the fiber grating temperature sensor (10) are led out, the packaged fiber grating strain sensor (9) is fixedly connected to an outer-layer steel wire (3) of the connecting cylinder (4), the packaged fiber grating temperature sensor (10) is suspended on the steel wire (3) of the connecting cylinder (4), holes (5-1) are punched in the wire dividing plate (5), and a preserved steel pipe (7) is buried in advance in the connecting cylinder (4) and the anchor cup (1). The system improves survival rates of the fiber grating sensor and the fibers in cable manufacturing and application processes, ensures reliability of the embedding technology of the fiber grating sensor, and effectively leads a fiber grating signal out of the cable body without distortion.
