Projektbeschreibung
Intelligente Städte erhalten Impulse durch modernste Fernerkundung
Die Erkennung von Parameteränderungen ist in vielen Bereichen unentbehrlich, von der Gesundheit über den Reifendruck bis hin zu intelligenten Gebäuden und industriellen Anwendungen. Die Technologie der verteilten faseroptischen Sensorik geht noch einen Schritt weiter. Der Aspekt der „Verteilung“ bezieht sich auf die Möglichkeit, Informationen nicht an bestimmten Stellen, sondern entlang des gesamten Glasfaserkabels zu lesen, ähnlich wie bei der diskreten im Gegensatz zur analogen Abtastung in der Elektronik. Im Rahmen des EU-finanzierten Projekts SLAM-DAST werden zwei hochmoderne Technologien der verteilten faseroptischen Sensorik in einem kostengünstigen Glasfaserkabel angewendet, um die Fernüberwachung riesiger Mengen an Informationen über Entfernungen von bis zu 100 km zu ermöglichen. Das System verspricht, das Potenzial spannender neuer Anwendungen für intelligente Städte – und nicht nur für diese – zu erhöhen.
Ziel
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.
