VLC technology, i.e. the pom lub teeb kev sib txuas lus (VLC), muaj kev sib kis ntawm cov ntaub ntawv siv lub teeb. LEDs yog siv los ua transmitters, thaum photodetectors uas hloov lub teeb teeb liab mus rau hauv hluav taws xob impulses pab raws li receivers.
Siv VLC thev naus laus zis hauv ib puag ncig kev lag luam, qhov no yog qhov kev sib tw tshiab. Cov chaw tsim khoom muaj qhov cuam tshuam, xws li cov phab ntsa, cov khoom siv hlau thiab cov tshuab, uas tuaj yeem cuam tshuam rau lawv txoj haujlwm. Cov kws tshawb fawb los ntawm Fraunhofer IOSB-INA thiab Ostwestfalen-Lippe University of Applied Sciences hauv Lemgo, Lub Tebchaws Yelemees tau ua qhov kev ntsuas ntsuas los ntawm kev sim peb yam cuam tshuam: ambient teeb, hmoov av e reflections los ntawm qeeb-tsav neeg thiab tsheb.
Txhawm rau ntsuas qhov tshwm sim uas tshwm sim sai dua li ib millisecond, muaj cov thev naus laus zis siab heev. Cov kws tshawb fawb los ntawm National Institute of Optics (INO) ntawm CNR ntawm Florence thiab University of Florence tau patented ib lub cuab yeej raws li lub tswv yim VLC (Visible Light Communication) kev sib txuas lus thev naus laus zis kom tso cai rau tsheb thiab cov cim kev sib txuas lus hauv tsawg dua ib millisecond thiab zam kev sib tsoo.
VLC thev naus laus zis yog ua raws li lub tswv yim ntawm kev hloov kho qhov siv ntawm LED teeb kom xa cov ntaub ntawv digital: siv cov kab ke no thiab lub teeb pom kev ntawm tib neeg lub qhov muag, cov cuab yeej patented tso cai rau lub teeb tsheb thiab tsheb sib pauv cov ntaub ntawv wireless hauv tsawg dua. millisecond thiab zam kev cuam tshuam thiab txaus ntshai maneuvers. Txhua xyoo, qhov tseeb, nyob ib ncig ntawm 1.3 lab tus tib neeg tuag hauv kev sib tsoo hauv ntiaj teb, 3287 tus neeg ib hnub. Kev tsim cov cuab yeej muaj peev xwm tiv thaiv kev sib tsoo yuav ua rau txoj kev nyab xeeb dua thiab lub neej ntawm cov neeg tsav tsheb yooj yim dua.
Cov cuab yeej siv, tam sim no siv tau rau kev lag luam tsheb, kev teeb pom kev zoo rau pej xeem thiab cov paib txoj kev, yav tom ntej tuaj yeem siv rau ntau yam kev lag luam thiab pej xeem, xws li kev tiv thaiv, kev kho mob).
Cov thev naus laus zis tau nthuav tawm hauv kev ua haujlwm ua haujlwm, suav nrog cov thev naus laus zis hauv nqe lus nug nrog 5G thev naus laus zis, nrog kev ua tiav zoo. Muaj kev koom tes nrog cov tuam txhab uas nyiam siv IP txuas nrog daim ntawv thov patent no. Daim ntawv thov patent tsis ntev los no tau raug foob rau ib qho ntawm VLC thev naus laus zis rau cov ntawv thov hauv tsev cia puav pheej thiab / lossis chaw lag luam. Nyob rau hauv txoj kev no nws muaj peev xwm muab cov kev pabcuam tshiab rau cov neeg siv, thaum tseem tso cai rau lawv qhov chaw txawm tias nyob hauv ib puag ncig hauv tsev uas GPS thev naus laus zis tsis ua haujlwm.
