No full textThe present invention relates to a process for continuously monitoring, in real time and at different altitudes, airborne pollutants. In particular, by using a multi-rotor flying platform, a fluid dynamic conveyance system, a specific sensor and a remote transmission system for transmitting the collected data, it is possible to monitor the presence, and possibly also the concentration, of airborne pollutants along vertical transepts and/or spatial trajectories. The process is implemented by coupling single elements, appropriately built and integrated, according to a predefined sequence and by imposing a certain operational procedure. In particular, it must be pointed out that: - the multi-rotor platform has no humans aboard and is controlled remotely, although it includes an on-board automatic flight stabilization system and a system for stopping the flight in the event of failures and/or malfunctions. - the fluid dynamic conveyance system consists of a truncated-cone element arranged in the upper part of the platform and securely anchored thereto; more in detail, the length of this element is such that it allows the monitored air to be taken partly outside the interference field of the rotors, and the flow inlet and outlet areas are so arranged as to allow the air to flow without any hindrance. - the airborne pollutant sensor is located in the upper part of the platform, at the base of the fluid dynamic conveyance system, and its sensitive part is immersed in the outgoing flow. The platform, assembled with the fluid dynamic conveyance system, a specific sensor and a system for remotely transmitting the collected data, is flown along vertical trajectories where stop points are imposed at different altitudes and repositioning shifts are made by means of translational movements. The vertical transepts are obtained by imposing paths that follow lines orthogonal to the ground plane and with one vertex lying therei
New guidelines for Environmental Monitoring and advanced technologies for 3D field data acquisition
No full textNegli ultimi anni il modello “sorgente-percorso-bersaglio” è diventato un approccio comune a più settori scientifici per affrontare problematiche più o meno complesse in ambito ambientale.
Tale modello pur mostrando la sua validità nel discretizzare gli “attori”, gli scenari e le relative interazioni, ha portato alla luce anche gli attuali limiti connessi alle tecniche ed alle tecnologie coinvolte nelle fasi di acquisizione dei dati sul campo; in particolare, va sottolineato che questi ultimi risultano sempre indispensabili sia nella fase di “scoperta” delle nuove fenomenologie, sia in quella di validazione dei modelli numerici.
Nel lavoro qui sinteticamente introdotto verranno presentate, attraverso esempi applicativi basati su indagini condotte dal nostro gruppo di ricerca, nuove tecniche e tecnologie per il campionamento nella e dalla matrice aria di parametri ambientali, cercando di evidenziarne non solo l’efficacia ma, anche le nuove relazioni funzionali introdotte a supporto della modellistica numerica.
In particolare, partendo dai requisiti di missione (in particolare dallo scenario operativo, dalla sensoristica e dai sistemi di propulsione/sostentamento, guida e controllo) verranno proposte le piattaforme volanti più idonee a supporto dell’attività di campionamento, approfondendo anche quelle “unmanned”.
Nel panorama delle tecnologie relative al “remote sensing” saranno presentate esperienze dirette relative allo sviluppo di sistemi UAV LTA dotati di sensori a “film spesso”, SAS, biosensori e termografia IR.
I dati rilevati sino ad oggi in recenti campagne di acquisizione condotte nella regione Campania, raccolti con sistemi prototipali a tecnologia “mista”, saranno mostrati supportando considerazioni di carattere qualitativo per sviluppi futuri ed in particolare nell’ambito dell’ingegneria sanitaria ambientale.
L’originalità di quanto emerso nelle indagini appena citate è connessa anche all’approccio utilizzato per la discretizzazione dello “scenario/percorso” da osservare, considerato “continuous full 3D” e non semplicemente analizzato attraverso piani rappresentativi. Inoltre, ogni campagna di prelievi è stata effettuata con la sinergia di competenze e strumenti multidisciplinari (ingegneria, microbiologia, meteorologia, ecologia, ...) permettendo delle correlazioni tra fenomenologie apparentemente “sconnesse” e tracciando nuove linee guida per un approccio non convenzionale al monitoraggio ambientale

Aerial infrared thermography: an effective tool to support government bodies in environmental police actions
No full textThe activities of our research group, “Environmental Sanitary Engineering” of the Department of Environmental Science - University of Naples PARTHENOPE, are focused on the following:
- Environmental pollution (prevention, monitoring, modeling and controlling);
- Environmental reclaim processes and technologies (water, soil and gas emissions treatment, reutilization and enhancement);
- Integrated and sustainable resources management.
In regard to the previously mentioned activities, our research group started the development of several scientific applied researches, discovering new methods and new technologies to perform an advanced environmental monitoring; particularly, the applied system is distinguished by joined use of aerial platforms (“manned” and “unmanned”) and advanced sensors (IR cameras HD, thick film solid state sensors, biosensors, QCM, digital HD photo/video 360°, etc.). Our system allows a 3D environmental monitoring according to “source – path – target” model; as matter of fact, the monitoring so improved allow us a full description of the investigated environmental scenario.
Moreover, during last years we cooperate with several specialized police forces and environmental protection agencies to detect Illegal sanitary sewer and storm-drain connections, Illegal discharges, illegal landfills and other “anomalies” produced by illegal actions.
So far we have scanned several miles of the coast and flown on critical zones using different aerial platforms technologies (ULM, UAV LTA, Tethered Balloon, multirotors mini-UAV) and a digital HD IR-Camera (manufactured by FLIR): a university curriculum for environmental police specialists was developed and, today, our expertise and specific equipment could add valuable assistance to support Government Bodies in environmental police actions.
The presentation scheduled at first the close examination of the operational scenario and, subsequently it brought to the definition of the integrated system and of the validating technologies; it will finally exhibit the effectiveness of the integrated system through the analysis of applied "test beds"
