UWB ultra-wideband positioning signals tau cuam tshuam thiab cuam tshuam los ntawm ib puag ncig ib puag ncig xws li phab ntsa, iav, thiab cov khoom siv sab hauv xws li desktops thaum lub sijhawm nthuav tawm, ua rau muaj kev cuam tshuam ntau yam.Lub teeb liab hloov pauv hauv ncua sij hawm, amplitude, thiab theem, uas ua rau lub zog attenuation thiab txo qis ntawm cov teeb liab-rau-suab nrov piv, ua rau lub fact tias cov thawj mus txog lub teeb liab tsis ncaj qha, ua rau muaj ntau yam yuam kev thiab ib tug txo nyob rau hauv positioning raug. .Yog li ntawd, kev ua haujlwm zoo ntawm cov nyhuv multipath tuaj yeem txhim kho qhov tseeb ntawm qhov chaw, thiab cov txheej txheem tam sim no rau suppressing multipath feem ntau muaj xws li MUSIC, ESPRIT, thiab ntug kev tshawb nrhiav cov tswv yim.
3. NLOS impact
Line-of-sight propagation (LOS) yog thawj zaug, thiab yuav tsum tau ua ua ntej kom ntseeg tau tias qhov tseeb ntawm cov teeb liab ntsuas tau, thaum cov xwm txheej ntawm lub hom phiaj ntawm lub xov tooj ntawm tes thiab lub hauv paus chaw nres tsheb tsis tuaj yeem ua tiav, kev nthuav tawm ntawm lub teeb liab tsuas yog ua tiav nyob rau hauv tsis-line-of-pom tej yam kev mob xws li refraction thiab diffraction.Nyob rau lub sijhawm no, lub sijhawm ntawm thawj tus mem tes tuaj txog tsis sawv cev rau tus nqi tiag tiag ntawm TOA, thiab cov kev taw qhia ntawm thawj tus mem tes tuaj txog tsis yog tus nqi tiag tiag ntawm AOA, uas yuav ua rau muaj qhov yuam kev ntawm qhov chaw.Tam sim no, txoj hauv kev tseem ceeb los tshem tawm qhov tsis yog-kab-ntawm-pob qhov yuam kev yog Wylie txoj kev thiab txoj kev sib raug zoo tshem tawm.
4. Qhov cuam tshuam ntawm tib neeg lub cev ntawm qhov chaw raug
Lub ntsiab tseem ceeb ntawm tib neeg lub cev yog dej, dej ntawm UWB wireless pulse teeb liab muaj lub zog nqus, ua rau lub teeb liab lub zog attenuation, xws li cov ntaub ntawv sib txawv, thiab cuam tshuam rau qhov kawg ntawm qhov chaw.
5. Kev cuam tshuam ntawm cov teeb liab nkag mus tsis muaj zog
Txhua lub teeb liab nkag mus rau ntawm phab ntsa thiab lwm qhov chaw yuav tsis muaj zog, UWB tsis muaj qhov tshwj xeeb.Thaum UWB qhov chaw nkag mus rau phab ntsa cib zoo tib yam, lub teeb liab yuav tsis muaj zog li ntawm ib nrab.Kev hloov pauv ntawm lub sijhawm xaim hluav taws xob vim yog kev nkag mus rau phab ntsa kuj tseem cuam tshuam rau qhov tseeb ntawm qhov chaw.
Vim tib neeg lub cev, lub teeb liab nkag tau los ntawm qhov tseeb ntawm qhov cuam tshuam yog qhov nyuaj rau kev hla, NXP thiab German LaterationXYZ lub tuam txhab yuav dhau los ntawm cov txheej txheem tshiab sensor layout kev daws teeb meem los txhim kho UWB thev naus laus zis, tsis tau muaj ib qho kev qhia tshwj xeeb ntawm cov txiaj ntsig tshiab. , Kuv tsuas tuaj yeem raug tso tawm los ntawm lub vev xaib raug cai ntawm NXP cov lus tshaj tawm yav dhau los los ua qhov cuam tshuam kev kwv yees.
Raws li kev txhawb nqa los txhim kho qhov raug ntawm UWB, Kuv ntseeg tias qhov no yog thawj zaug ntawm tag nrho NXP raws li lub ntiaj teb tus thawj coj UWB neeg ua si los cuam tshuam nrog cov tuam txhab tsim khoom lag luam tam sim no ntawm kev hloov pauv loj hauv qhov xwm txheej thiab kev tiv thaiv kev lag luam.Tom qab tag nrho, UWB thev naus laus zis tam sim no tseem nyob rau theem pib ntawm kev txhim kho, thiab cov nqi sib xws, daim ntawv thov, thiab nplai tseem tsis tau ruaj khov, lub sijhawm no, cov tuam txhab tsim khoom hauv tsev tau txhawj xeeb txog UWB cov khoom sai li sai tau rau thaj av. thiab kis tau, mus txeeb lub khw, tsis muaj sij hawm los saib xyuas UWB qhov tseeb los txhim kho kev tsim kho tshiab.NXP, raws li ib tug ntawm cov saum toj kawg nkaus players nyob rau hauv lub teb ntawm UWB, muaj ib tug ua tiav cov khoom ecosystem raws li zoo raws li ntau xyoo ntawm kev sib sib zog nqus plowing ntawm cov ntaub ntawv sau zog, ntau xis nyob rau hauv lub UWB innovation.
Qhov thib ob, NXP lub sijhawm no mus rau millimeter-theem UWB, kuj pom qhov tsis muaj peev xwm ntawm kev txhim kho yav tom ntej ntawm UWB thiab ntseeg tau tias kev txhim kho qhov tseeb yuav coj cov ntawv thov tshiab rau kev ua lag luam.
Hauv kuv lub tswv yim, qhov upside ntawm UWB yuav txuas ntxiv txhim kho nrog kev nce qib ntawm 5G "txoj kev tsim kho tshiab", thiab txuas ntxiv nthuav nws cov nqi sib koom ua ke hauv cov txheej txheem ntawm kev txhim kho kev lag luam ntawm 5G ntse empowerment.
Yav dhau los, nyob rau hauv 2G / 3G / 4G network, mobile positioning scenarios tau tsom rau kev hu xov tooj thaum muaj xwm ceev, kev nkag mus rau qhov chaw raug cai, thiab lwm yam kev siv, qhov kev xav tau qhov tseeb ntawm qhov chaw tsis siab, raws li Cell ID ntxhib qhov tseeb qhov tseeb ntawm kaum ntawm meters mus rau pua pua. ntawm meters.Thaum 5G siv txoj kev coding tshiab, beam fusion, loj-scale kav hlau txais xov arrays, millimeter yoj spectrum, thiab lwm yam technologies, nws loj bandwidth thiab kav hlau txais xov array technology, muab lub hauv paus rau high-precision nrug ntsuas thiab high-precision lub kaum sab xis ntsuas.Yog li ntawd, lwm qhov ntawm UWB sprint nyob rau hauv qhov tseeb yog kev txhawb nqa los ntawm cov keeb kwm yav dhau los, thev naus laus zis thev naus laus zis, thiab kev cia siab rau kev thov txaus, thiab UWB qhov tseeb sprint no tuaj yeem suav tias yog kev teeb tsa ua ntej kom tau raws li kev hloov pauv ntawm kev txawj ntse digital.
Cov lag luam twg yuav Millimeter UW qhib?
Tam sim no, kev lag luam kev faib tawm ntawm UWB yog qhov tseem ceeb ntawm B-end dispersion thiab C-end concentration.Hauv daim ntawv thov, B-kawg muaj cov ntaub ntawv siv ntau dua, thiab C-kawg muaj qhov xav paub ntau ntxiv rau kev ua haujlwm mining.Hauv kuv lub tswv yim, qhov kev tsim kho tshiab no tsom mus rau qhov chaw ua haujlwm tau sib sau ua ke qhov zoo ntawm UWB nyob rau hauv qhov tseeb qhov chaw, uas tsis yog tsuas yog coj cov kev ua tau zoo rau cov ntawv thov uas twb muaj lawm tab sis kuj tsim cov hauv kev rau UWB los qhib qhov chaw thov tshiab.
Hauv kev ua lag luam B-kawg, rau cov chaw ua si, cov chaw tsim khoom, cov lag luam, thiab lwm yam xwm txheej, qhov chaw tsis sib haum xeeb ntawm nws thaj chaw tshwj xeeb yog qhov tseeb, thiab qhov chaw qhov tseeb tuaj yeem lav tau zoo ib yam, thaum cov xwm txheej zoo li no tseem muaj qhov xav tau ruaj khov rau qhov kev nkag siab qhov tseeb, los yog yuav dhau los ua millimeter-theem UWB yuav sai sai no yog tsom rau qhov zoo ntawm kev ua lag luam.
Nyob rau hauv qhov xwm txheej mining, nrog rau kev nce qib ntawm kev txawj ntse mine kev tsim kho, fusion kev daws teeb meem ntawm "5G + UWB qhov chaw" tuaj yeem ua rau lub tshuab mining ntse ua tiav qhov chaw nyob hauv lub sijhawm luv luv, ua tiav kev sib xyaw ua ke ntawm qhov tseeb qhov chaw thiab kev siv hluav taws xob tsawg, thiab paub txog cov yam ntxwv ntawm kev ua haujlwm siab, muaj peev xwm loj thiab lub sijhawm tos ntev, thiab lwm yam, tib lub sijhawm, raws li kev tswj hwm kev nyab xeeb ntawm mine, nws tuaj yeem siv los xyuas kom muaj kev nyab xeeb ntawm mine thiab kev tswj kev nyab xeeb ntawm mine.Nyob rau tib lub sijhawm, raws li qhov xav tau nyuaj rau kev tswj hwm kev nyab xeeb ntawm kuv, UWB tseem yuav siv rau hauv kev tswj hwm txhua hnub ntawm cov neeg ua haujlwm, thiab tsheb khiav.Tam sim no, lub teb chaws muaj qee qhov ntsuas ntawm cov mines txog 4000 los yog li ntawd, thiab qhov nruab nrab qhov kev thov rau txhua qhov chaw nres tsheb thee yog li 100 lossis li ntawd, los ntawm qhov uas nws tuaj yeem kwv yees tias tag nrho cov kev thov rau qhov chaw nres tsheb thee hauv paus yog hais txog. 400,000, tus naj npawb ntawm cov thee miners tag nrho txog 4 lab tus tib neeg los yog li ntawd, raws li 1 tus neeg 1 daim ntawv lo, qhov kev thov rau UWB tags txog 4 lab los yog li ntawd.Raws li cov neeg siv khoom kawg tam sim no los yuav ib tus nqi lag luam, kev lag luam thee hauv UWB "chaw nres tsheb hauv paus + tag" kho vajtse lag luam yog kwv yees li 4 billion hauv cov nqi tso tawm.
Mining thiab mining zoo ib yam li cov xwm txheej uas muaj kev pheej hmoo siab thiab cov roj rho tawm, cov chaw tsim hluav taws xob, cov nroj tsuag tshuaj, thiab lwm yam., kev tswj xyuas kev nyab xeeb xav tau rau qhov kev xav tau ntawm qhov tseeb yog siab dua, UWB qhov chaw qhov tseeb rau millimeter-theem kev txhim kho yuav pab sib sau ua ke nws qhov zoo hauv thaj chaw zoo li no.
Hauv kev tsim khoom lag luam, kev tsim khoom, thiab kev xa khoom, UWB tau dhau los ua cov cuab yeej rau kev txo nqi thiab kev ua haujlwm zoo.Cov neeg ua haujlwm siv cov khoom siv tes nrog UWB thev naus laus zis tuaj yeem nrhiav tau thiab tso ntau qhov chaw;Kev tsim kho ntawm kev tswj hwm kev sib koom ua ke ntawm UWB thev naus laus zis hauv kev tswj hwm cov khoom lag luam tuaj yeem saib xyuas txhua yam khoom siv thiab cov neeg ua haujlwm hauv cov tsev khaws khoom hauv lub sijhawm tiag tiag, thiab ua tiav cov khoom lag luam tswj hwm, kev tswj hwm cov neeg ua haujlwm, thiab tib lub sijhawm kuj ua tiav cov khoom siv tsis raug thiab tsis raug. turnover los ntawm AGV cov cuab yeej, uas tuaj yeem txhim kho kev ua haujlwm zoo.
Tsis tas li ntawd, lub millimeter dhia ntawm UWB tseem tuaj yeem qhib cov ntawv thov tshiab hauv kev thauj mus los.Tam sim no, lub tsheb ciav hlau txoj kev tswj hwm lub luag haujlwm feem ntau yog nyob ntawm qhov chaw satellite ua kom tiav, rau qhov chaw nyob hauv av ib puag ncig nrog rau hauv nroog cov tsev siab siab, canyons, thiab lwm yam xwm txheej, qhov chaw satellite yog qhov ua tsis tiav.UWB thev naus laus zis hauv tsheb ciav hlau CBTC qhov chaw thiab kev taw qhia, kem rau hauv kev sib tsoo kom tsis txhob muaj kev sib tsoo thiab ceeb toom ntxov, tsheb ciav hlau nres, thiab lwm yam, tuaj yeem muab kev txhawb nqa kev ntseeg siab dua rau kev nyab xeeb thiab tswj kev thauj mus los.Tam sim no, hom ntawv thov no hauv Tebchaws Europe thiab Tebchaws Meskas tau tawg ua daim ntawv thov.
Hauv kev ua lag luam C-terminal, UWB precision mus rau millimeter-theem kev txhim kho yuav qhib cov ntawv thov tshiab uas tsis yog cov yuam sij digital rau lub tsheb.Piv txwv li, tsis siv neeg valet nres tsheb, tsis siv neeg them nyiaj, thiab lwm yam.Nyob rau tib lub sijhawm, raws li kev txawj ntse technology, kuj tuaj yeem tuaj "kawm" tus neeg siv cov qauv kev txav thiab tus cwj pwm, thiab txhim kho kev ua haujlwm ntawm kev tsav tsheb tsis siv neeg.
Hauv kev lag luam ntawm cov neeg siv khoom siv hluav taws xob, UWB tuaj yeem dhau los ua tus qauv thev naus laus zis rau cov xov tooj smartphones hauv qab nthwv dej ntawm lub tsheb-tshuab sib cuam tshuam ntawm cov yuam sij tsheb digital.Ntxiv rau qhov qhib qhov chaw thov dav dav rau kev tso npe thiab tshawb nrhiav cov khoom lag luam, UWB qhov kev txhim kho qhov tseeb tuaj yeem qhib qhov chaw thov tshiab rau cov khoom siv sib cuam tshuam.Piv txwv li, UWB qhov tseeb muaj peev xwm tswj tau qhov kev ncua deb ntawm cov khoom siv, los kho qhov kev tsim kho qhov tseeb, rau qhov kev ua si, suab, thiab yees duab kom muaj kev paub zoo dua.
