The distributed optical fiber sensing technology has the advantages of large data acquisition amount, small sampling interval, high testing precision, long distance and the like compared with the traditional monitoring method. In recent years, the distributed optical fiber sensing technology is developed rapidly, and has a great deal of engineering application in the fields of communication, civil engineering, energy, rock and soil and the like, and monitoring aspects such as pile foundation structure, tunnel deformation, slope instability, landslide instability and the like, but reports that the technology is adopted to simultaneously monitor deformation damage of a granary and storage capacity environment (temperature) in a granary are rarely seen at home and abroad.
