DTS (Distributed Temperature Sensing) is a fiber-optic technology that uses backscattered light to measure temperature continuously along an optical fiber. NECLA applies DTS in distributed acoustic and environmental sensing, enabling real-time monitoring of power lines, pipelines, and infrastructure. DTS provides scalable, non-intrusive sensing capabilities, and when paired with AI models, it allows researchers to detect anomalies, prevent failures, and ensure system reliability across large-scale networks.
Field trials of ambient noise-based automated methods for manhole localization and condition diagnostics using a real-time DAS/DTS integrated system were conducted. Crossreferencingmultiple sensing data resulted in a 94.7% detection rate and enhanced anomaly identification.
