Compania american\u0103 de telecomunica\u021bii Verizon \u0219i compania japonez\u0103 NEC tocmai au finalizat cu succes<\/a><\/noindex> testele de pe teren ale sistemului integrat de monitorizare a mediului urban \u0219i a evenimentelor prin intermediul liniilor obi\u0219nuite de fibr\u0103 optic\u0103. Nu sunt necesare investi\u021bii globale noi \u2013 toate cablurile de fibr\u0103 optic\u0103 au fost deja instalate de mult timp \u00een p\u0103m\u00e2nt de c\u0103tre compania Verizon \u0219i sunt folosite pentru transmiterea de date \u00een re\u021beaua sa. Acesta este aspectul unic al proiectului: pentru prima dat\u0103, operatorul a folosit linii comerciale de fibr\u0103 optic\u0103 active pentru colectarea datelor.<\/p>\n

Tehnologie monitoriz\u0103rii<\/a><\/noindex> Datele seismice \u0219i condi\u021biile de temperatur\u0103 ale cablurilor de fibr\u0103 optic\u0103 au fost utilizate timp de aproximativ 10 ani, de exemplu, \u00een domeniul extrac\u021biei de petrol. \u00cen ora\u0219, aceast\u0103 tehnologie este atractiv\u0103 pentru monitorizarea circula\u021biei \u0219i a evenimentelor de pe str\u0103zi, precum \u0219i pentru controlul st\u0103rii infrastructurii urbane, sub forma drumurilor, tunelurilor, podurilor \u0219i cl\u0103dirilor. \u00cen cadrul testelor, sistemul de monitorizare Verizon \u0219i NEC, bazat pe AI (re\u021bea neural\u0103 convolu\u021bional\u0103), a putut determina densitatea circula\u021biei \u00een fluxul de ma\u0219ini, vectorul de mi\u0219care \u0219i accelera\u021bia anumitor vehicule, greutatea acestora, precum \u0219i incidentele de pe drum (coliziuni \u0219i chiar \u00eempu\u0219c\u0103turi). Aceast\u0103 informa\u021bie va ajuta nu doar la \u00eembun\u0103t\u0103\u021birea circula\u021biei, ci \u0219i la sprijinirea serviciilor de \u201eprim r\u0103spuns\u201d, cum ar fi poli\u021bia, ambulan\u021ba \u0219i echipele de salvare.<\/p>\n

Principiul de func\u021bionare al unui astfel de sistem de monitorizare se bazeaz\u0103 pe analiza dispersiei inverse a semnalului optic (eco) \u00een cablul de fibr\u0103 optic\u0103, atunci c\u00e2nd deforma\u021biile de temperatur\u0103 sau vibra\u021biile genereaz\u0103 o interferen\u021b\u0103 fizic\u0103 \u00een liniile de comunica\u021bie, care este corectat\u0103 de transceiverele optice. Dac\u0103 aceste informa\u021bii sunt captate de receptoare speciale \u0219i analizate cu ajutorul AI, atunci se pot corela evenimentele specifice cu fiecare sector \u201eascultat\u201d.<\/p>\n

Compania Verizon \u00ee\u0219i extinde activ infrastructura de fibr\u0103 optic\u0103. \u00cen fiecare lun\u0103, aceasta \u00ee\u0219i cre\u0219te lungimea infrastructurii cu aproximativ 1400 mile (2253 km). \u00cen cazul \u00een care serviciul de monitorizare a situa\u021biei de pe str\u0103zi devine solicitat, Verizon este preg\u0103tit\u0103 s\u0103-l implementeze pe tot teritoriul Statelor Unite, unde este prezent\u0103 sau unde este nevoie.<\/p>\n
