Den amerikanska teleoperat\u00f6ren Verizon och det japanska f\u00f6retaget NEC har just framg\u00e5ngsrikt avslutat<\/a><\/noindex> F\u00e4ltpr\u00f6vningar av ett integrerat \u00f6vervakningssystem f\u00f6r den urbana milj\u00f6n och h\u00e4ndelser med hj\u00e4lp av vanliga optiska kommunikationslinjer. Inga nya globala investeringar kr\u00e4vs \u2013 alla optiska kablar har redan l\u00e4nge lagts i marken av Verizon och anv\u00e4nds f\u00f6r datatransmission i deras n\u00e4tverk. Detta \u00e4r projektets unikhet: f\u00f6r f\u00f6rsta g\u00e5ngen har operat\u00f6ren anv\u00e4nt aktiva kommersiella optiska kommunikationslinjer f\u00f6r datainsamling.<\/p>\n

\"Vanliga<\/p>\n

Tekniken f\u00f6r sp\u00e5rning<\/a><\/noindex> Seismiska data och temperaturmilj\u00f6 f\u00f6r optiska kablar har anv\u00e4nts i ungef\u00e4r 10 \u00e5r, till exempel inom oljeutvinning. I staden \u00e4r det attraktivt att anv\u00e4nda denna teknologi f\u00f6r \u00f6vervakning av r\u00f6relse och h\u00e4ndelser p\u00e5 gatorna, samt f\u00f6r att kontrollera tillst\u00e5ndet hos den urbana infrastrukturen i form av v\u00e4gar, tunnlar, broar och byggnader. I Verizon och NEC:s tester lyckades \u00f6vervakningssystemet baserat p\u00e5 AI (konvolutionellt neuralt n\u00e4tverk) best\u00e4mma trafikfl\u00f6det, r\u00f6relseriktning och acceleration av enskilda bilar, deras lastvikt, samt incidenter p\u00e5 v\u00e4garna (kollisioner och till och med skott). Denna information kommer inte bara att f\u00f6rb\u00e4ttra trafiken, utan \u00e4ven hj\u00e4lpa \"f\u00f6rsta responder\"-tj\u00e4nster som polis, ambulans och r\u00e4ddningstj\u00e4nst.<\/p>\n

Principen f\u00f6r hur ett s\u00e5dant \u00f6vervakningssystem fungerar baseras p\u00e5 analys av bak\u00e5tspridningen av det optiska signalet (ekot) i en fiberoptisk kabel, n\u00e4r temperaturdeformationer eller vibrationer skapar fysiska st\u00f6rningar i kommunikationslinjerna, vilka justeras av optiska s\u00e4ndare och mottagare. Om denna information samlas in av specialutrustning och analyseras med hj\u00e4lp av AI kan specifika h\u00e4ndelser kopplas till varje \"avlyssnad\" sektor.<\/p>\n

Verizon expanderar aktivt sitt fiberoptiska n\u00e4tverk. Varje m\u00e5nad \u00f6kar de l\u00e4ngden p\u00e5 infrastrukturen med cirka 1400 miles (2253 km). Om efterfr\u00e5gan p\u00e5 tj\u00e4nsten f\u00f6r \u00f6vervakning av l\u00e4get p\u00e5 gatorna \u00f6kar, \u00e4r Verizon beredda att rulla ut den i hela USA, d\u00e4r de n\u00e4rvarar eller det finns efterfr\u00e5gan.<\/p>\n
