L'operatore di telecomunicazioni americano Verizon e la compagnia giapponese NEC hanno appena completato con successo<\/a><\/noindex> test di campo di un sistema integrato di monitoraggio dell'ambiente urbano e degli eventi attraverso normali linee di fibra ottica. Nessun grande investimento globale necessario: tutti i cavi ottici sono stati gi\u00e0 interrati da tempo dall'azienda Verizon e vengono utilizzati per la trasmissione dei dati nella sua rete. La particolarit\u00e0 del progetto \u00e8 che, per la prima volta, l'operatore ha sfruttato linee commerciali ottiche esistenti per la raccolta dei dati.<\/p>\n

\"Le<\/p>\n

Tecnologia monitoraggio<\/a><\/noindex> I dati sismici e le temperature ambientali dei cavi ottici vengono utilizzati da circa 10 anni, ad esempio nel settore dell'estrazione petrolifera. In citt\u00e0, questa tecnologia potrebbe essere allettante per monitorare il traffico e gli eventi nelle strade, oltre a controllare lo stato delle infrastrutture urbane come strade, tunnel, ponti e edifici. Nei test condotti da Verizon e NEC, il sistema di monitoraggio basato sull'IA (rete neurale convoluzionale) \u00e8 stato in grado di determinare la densit\u00e0 del traffico, la direzione di movimento e l'accelerazione di singoli veicoli, il loro peso, cos\u00ec come incidenti stradali (collisioni e persino spari). Queste informazioni non solo aiuteranno a migliorare il traffico, ma anche le agenzie di \"pronto intervento\" come la polizia, l'ambulanza e i servizi di salvataggio.<\/p>\n

Il principio di funzionamento di un sistema di monitoraggio di questo tipo si basa sull'analisi della retro scattering del segnale ottico (eco) all'interno del cavo in fibra ottica, dove le deformazioni termiche o le vibrazioni influenzano fisicamente le linee di comunicazione, le quali vengono corrette dai trasmettitori ottici. Se queste informazioni vengono raccolte tramite ricevitori specifici e analizzate con l'IA, \u00e8 possibile associare a ciascun settore \"ascoltato\" eventi ben definiti.<\/p>\n

Verizon sta attivamente ampliando la sua infrastruttura di cavi. Ogni mese aumenta la lunghezza della sua rete di circa 1400 miglia (2253 km). In caso di richiesta del servizio per monitorare la situazione sulle strade, Verizon \u00e8 pronta a estenderlo in tutto il territorio degli Stati Uniti, dove \u00e8 presente o dove sar\u00e0 richiesto.<\/p>\n
