Use Cases
A major importance of distributed sensing lies within the field of critical infrastructure monitoring. Three different use cases are planned for the flexible system: 1) Test the sensing system in high voltage power cables to monitor the temperature along the cable infrastructure, 2) The supervision of telecommunication infrastructure using an existing fiber network to detect events in the perimeter of the equipment like detection of fiber cables manipulation in data centers and 3) Investigate the supervision of water supply network to detect leakage induced temperature and strain changes in surrounding soil but also detect infrastructure manipulations .
Powerlines supervision
Distributed temperature and acoustic sensing will be used to collect information on the status of powerlines.
Also, FBG (Fiber Bragg Grating) arrays will be interrogated to further demonstrate and validate the flexibility of the system.
Telecommunication supervision
Using the system information will be collected on external impacts threatening the fiber infrastructure, e.g. fire, stress, heavy machinery in the perimeter of fiber cables that could risk fiber integrity. Investigations will be also performed to increase security of unmanned network sites.
Water supply supervision
Water leaks will be detected via changing sound generated by water flow, but also FBG array-based supervision to detect temperature and strain variation caused by lost water combined with methods of machine learning to detect water loss at an early stage.
