In recent years, fiber-optical distributed acoustic sensing (DAS) has been applied to various large-scale infrastructure monitoring areas in smart cities, leading a new generation of fiber-optic IoT for ground listening. However, its single-task-focused postprocessing methods cannot achieve real-time efficient event recognition and localization concurrently. this article, two-level multitask learning (MTL) enhanced DAS (sDAS) system is proposed, the first time, simultaneously realize...
The fiber-optic distributed acoustic sensor (DAS), which utilizes existing communication cables as its sensing media, plays an important role in urban infrastructure monitoring and natural disaster prediction. In the face of a wide, dynamic environment areas, fast, accurate DAS signal recognition method is proposed with end-to-end attention-enhanced ResNet model. preprocessing, objective evaluation used to compare distinguishability different input features Euclidean distance between...
