| description | The invention discloses a buried pipeline suspension state distributed optical fiber monitoring device and a monitoring method thereof, and belongs to the technical field of structure safe monitoring.The monitoring device comprises optical fiber sensors and a data acquisition instrument; the optical fiber sensors are longitudinally and parallelly fixed to the positions, equivalent to the 3 o'clock position, the 9 o'clock position and the 12 o'clock position on a clock, of the outer wall of a buried pipeline; and longitudinal strain data of the pipeline are obtained through the optical fiber sensors, bent stain data are extracted, and the suspension position and length of the pipeline are recognized according to the suspension pipeline additional bending moment distribution characteristics. Compared with a traditional pipeline monitoring method, the advantages of real-time monitoring, remote sensing and distributed measuring are achieved. The stain distribution state of the whole length of the pipeline can be |
