The invention discloses an intelligent device for detecting a sloping state of an optical cable cross-connecting cabinet. The optical cable cross-connecting cabinet comprises an optical cable cross-connecting cabinet base. The intelligent device is located on the optical cable cross-connecting cabinet base. The intelligent device comprises a weight m, a permanent
magnet A, a spring piece, a fixed point A, a
fiber grating, a fixed point B, an
optical fiber, a permanent
magnet B and a weight M. The weight m is connected with the permanent
magnet A, the spring piece adheres to the lower surface of the permanent magnet A, the
optical fiber is fixed to the spring piece through the fixed point A and the fixed point B, the
fiber grating is welded between two sections of optical cables, the permanent magnet B is arranged on the weight M, and the weight M is located on the optical cable cross-connecting cabinet base. According to the technical scheme, the intelligent device has the advantages of being passive, high in
electromagnetic interference resistance and sensitivity, resistant to
corrosion and long in service life, the safety, stability and reliability of the communication network operation are improved, and the fault risk is lowered.
