Research Progress of Pipeline Health Monitoring Based on Distributed Fiber Optic Sensing

Since its launch, the technology of distributed acoustic sensing (DAS) has garnered significant attention. DAS is a cutting-edge type of fiber-optic sensor technology that can be used for real-time, distributed, long-range monitoring. Researchers have made great strides in pipeline health monitoring in the last few years, and DAS technology has been the subject of extensive study. Beginning with the DAS operating principle, the fundamental idea behind DAS is explained, and the technical advancements of DAS are further clarified. The development of DAS application in pipeline health monitoring, including leakage monitoring, internal corrosion monitoring, and exterior intrusion monitoring, is then thoroughly introduced by going over several common tests. Lastly, a summary of the pressing issues and limitations facing the DAS-based pipeline health monitoring technology system is provided, along with an analysis of DAS's prospects for future development.
