Description du projet
Des villes intelligentes bénéficient d’une technologie de pointe de détection à longue distance
La détection des changements de paramètres est essentielle pour tous les domaines, de la santé à la pression des pneus en passant par les maisons intelligentes et les applications industrielles. Les technologies de détection distribuée par fibres optiques (D-FOS) permettent d’aller encore plus loin. L’aspect «distribution» fait référence à la capacité de lire les informations non pas à des endroits spécifiques mais tout au long du câble à fibre optique, à l’instar de l’échantillonnage discret ou analogique pour l’électronique. Le projet SLAM-DAST, financé par l’UE, intègre deux technologies D-FOS de pointe combinées à un câble à fibres optiques peu coûteux pour permettre la surveillance distante d’une grande quantité d’informations à des distances pouvant atteindre 100 km. Le système promet entre autres de renforcer les capacités de nouvelles applications très intéressantes pour les villes intelligentes.
Objectif
Distributed Acoustic Sensing (DAS) and Distributed Temperature-Strain Sensing (DTSS) are two ground-breaking Distributed Fibre Optic Sensor (D-FOS) technologies that allow large-scale measuring and mapping of acoustic vibrations, temperature, mechanical deformations, and pressure in a large variety of consumer-based, civil, industrial, and environmental applications, in particular for attaining the widespread technological nerve system in smart city environments, for instance in smart home/household monitoring (heating, survelliance, fire detection, structural heath, and so forth), as well as in product distribution/logistics (traffic, distribution and plant monitoring).
DAS and DTSS employ a low-priced optical fibre cable installed along the assets (e.g. homes/households in a neighborhood) to be monitored for up to 100 km through an interrogator equipment that sweeps a “virtual sensor” to measure the physical parameters individually at any cable point.
This project main objective is to develop, prototype and demonstrate, both in civil/industrial and especially in household/smart-city case studies, a new, cost-effective, Smart LightwAve Multi-modal Distributed Acoustic Strain and Temperature photonic sensing system (SLAM-DAST), which will integrate:
- Distributed Temperature and mechanical deformation (Strain) Sensing (DTSS) and
- Distributed Acoustic vibrations optical Sensing (DAS)
SLAM-DAST aims at securing the conditions of a disruptive market exploitation, at an industrial as well as at a large scale consumer-oriented level, of the project’s results by:
- supporting the product characterisation-standardisation through open access to performance test benches;
- adopting open innovation policies about general system architecture and embedded data pre-processing;
- promoting vendor interoperability through the use of open standards and formats;
- creating shared value through knowledge-spreading and international networking with key market access points.
