Detection device and detection method of optical fiber sensing device

The invention discloses a detection device and detection method for an optical fiber sensing device, and the device comprises two transverse plates, and the sides, away from each other, of the two transverse plates are fixedly connected with U-shaped plates. A vertical block is held and moved leftwards, the vertical plate drives a moving plate to move through a cross rod, the moving plate drives a circular block to move through a connecting rod, the circular block drives a sharp block to be separated from the top of a rubber strip and moves the vertical block leftwards or rightwards, the cross plate drives an optical fiber sensor to move, thrust on the vertical plate is released, and the optical fiber sensor is fixed. An electric telescopic rod is reversely started to extrude a rotating rod through a T-shaped block, and the rotating rod drives a rectangular block to move through a transverse block, so that the two optical fiber sensors move away from each other, and the positions of the optical fiber sensors
