The utility model relates to an intelligent type cable fiber grating strain transducer which is suitable for the cable bearing structures of cable-stayed bridges, suspension bridges, arch bridges and the like. The intelligent type cable fiber grating strain transducer comprises a fiber grating (1), first steel pipes (3), second steel pipes (2), a protective steel pipe (6) and a supporting seat (4), wherein the diameter of the second steel pipes (2) is smaller than the diameter of the first steel pipes (3) and is smaller than the diameter of the protective steel pipe (6), the middles of the second steel pipes (2) are axially provided with grooves, the middles of the first steel pipes (3) penetrate through a perforation at an upper area of the supporting seat (4) and are connected on the supporting seat (4), both ends of the protective steel pipe (6) are respectively sleeved at one end of the two first steel pipes (3), the other ends of the first steel pipes (3) are sleeved at one end of the second steel pipes (2), the fiber grating (1) penetrates through the second steel pipes (2), the first steel pipes (3) and the protective steel pipe (6), a grid area of the grating is arranged at the central position of the protective steel pipe (6), and tail fibers at both ends of the fiber grating (1) are led out from the other ends of the two second steel pipes (2). The utility model can enhance the survival rate of a fiber grating transducer and fibers in the manufacture and application processes of cables and ensures the reliability of the embedding process of the fiber grating transducer.
