STUDY ON DISTRIBUTED FIBER OPTICAL PIPELINE SECURITY&PRE-WARNING SYSTEM
This paper describes a novel pipelinesecurity & per-warning system based on distributed fiber optical sensing which detects micro-vibration along pipeline, through fiber cable laying in one ditch. A special optical path was designed by redundant optical fiber cores among fiber cable. This new sensor technology detects illegal excavation through detect optical phase changes. This innovative signal analysis technology can avoid the disturbance of light intensity fluctuation and phase fading. Excavator, digging and impact of freely falling body were used to test this pipeline security & per-warning system. Different type of cable, such as straight buried cable, steel wire armored cable and silicone tube, were all test in order to test sensitivity. Field trail shows that this system can detect, alarm and locate different third party interference along pipeline.
