The invention discloses an optical fiber transverse stress detector, and the detector comprises a plurality of assembly units which are sequentially connected from top to bottom, each assembling unitis cylindrical, a groove is formed in the upper surface of each assembling unit, a protruding part is arranged on the lower surface of each assembling unit, and the protruding parts and the grooves ofthe adjacent assembling units are matched. A plurality of longitudinal notches are formed in the periphery of the assembling unit and used for installing optical fibers. The protruding part of one assembling unit is matched with the groove of the other assembling unit, the protruding part and the groove of the other assembling unit are assembled in sequence to form an overall detector structure,a plurality of longitudinal notches are formed in the periphery of each assembling unit, and a through longitudinal notch is formed in the outer side of each overall detector structure so that the corresponding testing optical fiber can be installed. The detector can be inserted into a mounting hole needing to monitor transverse stress, and when a monitoring environment swings, the optical fiber transverse stress detector can deform in a high-precision and high-timeliness mode.
Description
technical field [0001] The invention belongs to the field of optical fiber sensing, and more specifically relates to an optical fiber transverse stress detector. Background technique [0002] Rescue environment monitoring is an important task in safety monitoring. It has the characteristics of large scale, large differences in emergency rescue environments, and real-time dynamic monitoring. Therefore, some conventional point-based monitoring methods can no longer meet the requirements. Optical time domain reflectometry is a new type of photoelectric sensing and monitoring technology. The optical time domain reflectometer works through the back Rayleigh scattering signal generated in the optical fiber under test. Therefore, the optical time domain reflectometer can measure the transverse direction of the light The stress reacts so that the loss of the fiber due to bending can be measured. [0003] In the prior art, the method of directly burying the optical fiber is usually ...
