Abstract: Systems and methods for utility pole localization employing a DFOS/DAS interrogator located at one end of an optical sensor fiber remotely capture dynamic strains on the optical sensor fiber induced by acoustic events. A captured two-dimensional spatiotemporal map in an ambient noisy environment is analyzed by a trained machine learning model which then automatically detects an area in which a pole is located without requiring domain knowledge. Original DFOS/DAS signals are separated into pole regions and non-pole region time series for machine learning model training. A contrastive loss function measures similarities between low-frequency and high-frequency features. A Gaussian distribution is applied to the original signals to generate weighted labels to eliminate effects of label noise. The machine learning model fuses low-frequency and high-frequency features in the frequency domain for pole region classification.

Abstract: A cooling system performance early warning method based on dictionary learning is disclosed. A sensor and an oil pump frequency converter are arranged on a cooler of the cooling system to measure operation data of the cooling system. A PLC controller is installed on the cooler to collect the measured operation data and connected with a cloud server, and the cloud server first performs offline dictionary learning on the data, so as to establish a performance cads warning model for each group of coolers respectively. After the offline dictionary learning stage is completed, an online early warning stage is entered, and the established performance early warning model is used to carry out a real-time performance early warning of the cooling system. The early warning method can use the established performance early warning model to carry out real-time performance early warning, which has the advantages of real-time, realizability and strong pertinence.

Abstract: A solar powered, self-contained DFOS extender that includes a wide-angle camera and a microphone. The DFOS extender monitors the perimeter constantly or at predetermined time intervals both visually and acoustically. It analyses these signals and if an alarming event is detected (such as an animal, a human, a car, or a truck seen or heard), then the DFOS extender generates a coded vibration via its in-built acoustic modem. These coded vibrations are detected by the fiber and an event log is generated. Consequently, a trespasser or false alarms (animals) are detected before they are within detectable distance of the underground DFOS optical sensor fiber. Advantageously, our DFOS extender can be placed in critical locations along a border where an increased detection range is desired and may later be relocated/reinstalled at other locations as well.
