In this paper, a new type of hull structure long base stress sensor is introduced. When the ship changes under external or internal forces, the fiber Bragg grating fixed between two bases is deformed. The deformation of the fiber grating and the wavelength change of the fiber grating are basically linear. By demodulating the end of the compensation algorithm, we can get the fiber wavelength and the ship structure stress. Therefore, the actual structural strength of the hull is accurately mastered, which provides a stable and reliable device for long-term detection and health monitoring of hull structure in the field of ocean ships.
