Optical fiber pre-warning systems (OFPS) based on Φ-OTDR are applied to many different scenarios such as oil and gas pipeline protection. The recognition of fiber vibration signals is one of the most important parts of this system. According to the characteristics of small sample set. we choose stochastic configuration network (SCN) for recognition. https://nnacilafwbkbaq.tokka-blog.com/35177677/the-impact-of-early-detection-and-intervention-on-congenital-heart-defects-in-infants-and-children-a-systematic-review
