| Abstract: | A new distributed fiber optic sensor for oil pipeline leakage detection based on OTDR was presented,which was fixed along oil pipeline and made use of characteristic of OTDR.The construction of sensor and simulate experiment were presented.The feasibility,the precise location in long distance,stability and anti-disturbance of this sensor were also discussed.The sensor can test the loss of optic fiber along fiber distance,and the distributed fiber optic sensor for oil pipeline leakage detection can detect and locate oil leakage in 15 min with the location precision being 3 m. |
