Thaum nws los txog rau kev them nyiaj tsis-inductive, nws yooj yim xav txog kev them nyiaj ETC, uas ua tiav kev them nyiaj tsis siv neeg ntawm lub tsheb nres los ntawm semi-active RFID xov tooj cua zaus sib txuas lus thev naus laus zis. Nrog kev siv zoo ntawm UWB thev naus laus zis, tib neeg kuj tuaj yeem paub txog lub rooj vag induction thiab txiav tawm tsis siv neeg thaum lawv mus ncig hauv subway.
Tsis ntev los no, Shenzhen daim npav tsheb npav platform "Shenzhen Tong" thiab Huiting Technology tau koom ua ke tso tawm UWB kev daws teeb meem them nqi ntawm "tsis-inductive off-line brake" ntawm lub rooj vag subway. Raws li ntau-chip complex RADIO frequency system, qhov kev daws teeb meem no siv tag nrho cov kev daws teeb meem kev ruaj ntseg ntawm "eSE + COS + NFC + BLE" ntawm Huiting Technology, thiab nqa UWB chip rau qhov chaw nyob thiab kev lag luam muaj kev nyab xeeb. Los ntawm lub xov tooj ntawm tes lossis daim npav tsheb npav uas muaj UWB chip, tus neeg siv tuaj yeem paub nws tus kheej thaum hla lub nres, thiab ua tiav qhov qhib thiab rho tawm ntawm tus nqi.
Raws li lub tuam txhab, qhov kev daws teeb meem no sib koom ua ke NFC, UWB thiab lwm yam kev cai tsav tsheb rau hauv lub nti Bluetooth SoC uas muaj zog tsawg, txo qhov nyuaj ntawm kev txhim kho lub rooj vag los ntawm kev hloov pauv modular, thiab sib xws nrog lub rooj vag NFC. Raws li daim duab raug cai, chaw nres tsheb UWB yuav tsum nyob ntawm lub rooj vag, thiab qhov ntau thiab tsawg ntawm tus nqi txiav tawm yog nyob hauv 1.3m.
Nws tsis yog qhov txawv txawv rau UWB (Ultra-wideband technology) siv rau hauv kev them nyiaj tsis-inductive. Ntawm Beijing International Urban rail Transit Exhibition thaum Lub Kaum Hli 2021, Shenzhen Tong thiab VIVO kuj tau ua qauv qhia txog daim ntawv thov "kev them nyiaj digital RMB tsis-inductive rau subway nres" raws li UWB technology, thiab tau txais kev them nyiaj tsis-inductive los ntawm UWB + NFC chip nqa los ntawm VIVO prototype. Ua ntej xyoo 2020, NXP, DOCOMO thiab SONY kuj tau tshaj tawm qhov kev ua qauv qhia txog UWB cov ntawv thov muag khoom tshiab hauv Mall, suav nrog kev them nyiaj tsis muaj kev xav, kev them nqi nres tsheb nkag tau, thiab kev tshaj tawm thiab kev lag luam meej.
Kev Tso Chaw Tseeb + Kev Them Nyiaj Tsis Muaj Kev Xav, UWB Nkag Mus Rau Kev Them Nyiaj Txawb
NFC, bluetooth, ir yog ib qho tseem ceeb hauv kev siv nyiaj ze ze. NFC (kev sib txuas lus ze ze) vim muaj kev ruaj ntseg siab, tsis tas yuav txuas nrog lub hwj chim, tam sim no hauv cov qauv tseem ceeb siv dav hauv xov tooj ntawm tes, hauv cov chaw xws li Nyiv Pooj thiab Kaus Lim Qab Teb, NFC xov tooj ntawm tes tuaj yeem siv ua daim npav IC, daim npav rho nyiaj, daim npav them nyiaj, thiab lwm yam.
UWB ultra-wideband thev naus laus zis, nrog rau lub teeb liab ultra-wideband (UWB-IR) nanosecond teb cov yam ntxwv, ua ke nrog TOF, TDoA / AoA rangeing algorithm, suav nrog kab pom (LoS) scenes thiab tsis pom (nLoS) scenes tuaj yeem ua tiav qhov tseeb ntawm centimeter. Hauv cov ntawv dhau los, Iot Media tau qhia txog daim ntawv thov hauv kev tso chaw sab hauv tsev, cov yuam sij tsheb digital thiab lwm yam hauv kev nthuav dav. UWB muaj cov yam ntxwv ntawm qhov tseeb ntawm qhov chaw siab, tus nqi kis tau siab, kev cuam tshuam teeb liab thiab kev cuam tshuam, uas muab nws cov txiaj ntsig ntuj hauv kev siv kev them nyiaj tsis-inductive.
Lub hauv paus ntsiab lus ntawm kev them nyiaj tsis muaj kev cuam tshuam ntawm lub rooj vag hauv av yog qhov yooj yim heev. Xov tooj ntawm tes thiab daim npav npav nrog UWB ua haujlwm tuaj yeem suav tias yog UWB mobile tag. Thaum lub hauv paus chaw nres tsheb pom qhov chaw ntawm lub tag, nws yuav xauv tam sim ntawd thiab ua raws li nws. UWB thiab eSE kev ruaj ntseg chip + NFC ua ke kom ua tiav qib nyiaj txiag kev nyab xeeb encryption them nyiaj.
Daim ntawv thov NFC + UWB, lwm daim ntawv thov nrov yog lub tsheb virtual key. Hauv kev lag luam ntawm cov yuam sij digital tsheb, qee cov qauv nruab nrab thiab siab ntawm BMW, NIO, Volkswagen thiab lwm lub npe tau txais yuav cov txheej txheem ntawm "BLE + UWB + NFC". Bluetooth chaw taws teeb sensing tsa UWB rau kev xa cov ntaub ntawv encryption, UWB siv rau kev pom qhov tseeb, thiab NFC siv ua cov txheej txheem thaub qab rau kev ua tsis tiav ntawm lub zog kom ua tiav kev tswj hwm qhib hauv ntau qhov deb thiab cov xwm txheej ntawm lub zog.
Qhov Chaw Nce UWB, Kev Ua tiav lossis Kev Ua Tsis Tau Zoo Nyob ntawm Sab Neeg Siv Khoom
Ntxiv rau qhov chaw raug, UWB kuj tseem ceeb heev hauv kev xa cov ntaub ntawv luv luv thiab ceev. Txawm li cas los xij, hauv kev lag luam Internet of Things, vim muaj kev qhia sai thiab kev lag luam nrov ntawm wi-fi, Zigbee, BLE thiab lwm yam qauv protocol, UWB tseem muaj peev xwm ua haujlwm tau zoo hauv tsev, yog li qhov kev thov hauv kev lag luam B-end tsuas yog nyob rau hauv lab, uas yog qhov sib txawv. Kev ua lag luam zoo li no nyuaj rau cov tuam txhab tsim khoom siv chip kom ua tiav kev nqis peev ruaj khov.
Tsav los ntawm kev thov kev lag luam, C-end neeg siv khoom Internet ntawm Yam tau dhau los ua qhov chaw sib ntaus sib tua tseem ceeb hauv lub siab ntawm cov chaw tsim khoom UWB. Cov khoom siv hluav taws xob rau cov neeg siv khoom, cov cim npe ntse, lub tsev ntse, lub tsheb ntse, thiab kev them nyiaj ruaj ntseg tau dhau los ua qhov tseem ceeb tshawb fawb thiab kev txhim kho ntawm NXP, Qorvo, ST thiab lwm lub tuam txhab. Piv txwv li, hauv cov teb ntawm kev tswj hwm kev nkag mus tsis raug, kev them nyiaj tsis raug thiab lub tsev ntse, UWB tuaj yeem kho qhov chaw hauv tsev raws li cov ntaub ntawv ID. Hauv cov khoom siv hluav taws xob rau cov neeg siv khoom, UWB xov tooj thiab lawv cov khoom siv kho vajtse tuaj yeem siv rau qhov chaw nyob hauv tsev, kev taug qab tsiaj, thiab kev xa cov ntaub ntawv sai.
Chen Zhenqi, CEO ntawm Newwick, lub tuam txhab UWB chip hauv tebchaws, ib zaug hais tias "xov tooj ntse thiab tsheb, ua qhov tseem ceeb tshaj plaws thiab cov chaw nres tsheb ntse hauv Is Taws Nem yav tom ntej ntawm txhua yam, kuj yuav yog lub khw loj tshaj plaws ntawm UWB thev naus laus zis". ABI Kev Tshawb Fawb tau kwv yees tias 520 lab lub xov tooj ntse UWB yuav raug xa tawm los ntawm xyoo 2025, thiab 32.5% ntawm lawv yuav raug koom ua ke nrog UWB. Qhov no muab ntau yam rau cov chaw tsim khoom UWB xav txog, thiab Qorvo xav tias cov khoom xa tuaj UWB yuav phim kev siv Bluetooth yav tom ntej.
Txawm hais tias kev cia siab tias kev xa khoom ntawm cov chips zoo, Qorvo tau hais tias qhov teeb meem loj tshaj plaws rau kev lag luam UWB yog qhov tsis muaj cov saw hlau ua lag luam tiav los txhawb nws. Cov tuam txhab lag luam chip upstream ntawm UWB suav nrog NXP, Qorvo, ST, Apple, Newcore, Chixin Semiconductor, Hanwei Microelectronics thiab lwm lub tuam txhab, thaum cov kwj deg nruab nrab muaj cov chaw tsim khoom sib xyaw module, cov chaw tsim khoom chaw nres tsheb, cov xov tooj ntawm tes thiab cov chaw tsim khoom kho vajtse peripheral.
Sai sai no lub tuam txhab tab tom koom nrog kev tsim cov UWB chip, ntau ntawm "MaoJian", tab sis tseem tsis muaj tus qauv ntawm cov chip, kev lag luam nyuaj rau tsim cov qauv kev sib txuas zoo li bluetooth, nruab nrab thiab qis dua ntawm cov khw muag khoom lag luam yuav tsum siv ntau daim ntawv thov, ua rau tus neeg siv khoom ntawm kev ua haujlwm ntawm UWB zaus ntawm kev siv, los ntawm qhov taw tes ntawm cov txiaj ntsig, Kev vam meej lossis kev ua tsis tiav ntawm kev ua lag luam UWB zoo li so ntawm sab neeg siv khoom.
Thaum Kawg
Qhov kev txhawb nqa ntawm UWB kev them nyiaj tsis muaj kev xav, ntawm ib sab tes, nyob ntawm seb cov xov tooj ntawm tes uas muaj UWB ua haujlwm puas tuaj yeem nrov hauv kev ua lag luam. Tam sim no, tsuas yog qee cov qauv ntawm Apple, Samsung, Xiaomi thiab VIVO txhawb nqa UWB, thiab OPPO kuj tso tawm "ib-khawm sib txuas" ntawm UWB lub xov tooj ntawm tes rooj plaub, yog li qhov nrov ntawm tus qauv thiab pej xeem tseem tsawg. Nws tseem yuav tsum tau pom tias nws puas tuaj yeem ntes tau NFC qhov nrov hauv xov tooj ntawm tes, thiab kev ncav cuag bluetooth qhov loj me tseem yog lub zeem muag. Tab sis txiav txim los ntawm "roll-in" ntawm cov tuam txhab xov tooj tam sim no, hnub ntawm UWB ua tus qauv yuav tsis deb dhau.
Ntawm qhov tod tes, muaj kev tsim kho tshiab tsis kawg ntawm cov xwm txheej kawg ntawm cov neeg siv khoom siv zaus siab. UWB rau kev taug qab cov neeg siv khoom, qhov chaw, kev tswj chaw taws teeb, kev them nyiaj tau nthuav dav los ntawm cov tuam txhab tsim khoom nruab nrab: Apple's Airtag, Xiaomi's One Finger, NiO's digital car keys, Huawei's fusion signal indoor positioning, NXP's ultra-wideband radar, Huidong's metro payment ... Tsuas yog ntau yam kev tsim kho tshiab los ua kom muaj zaus ntawm kev nkag mus rau cov neeg siv khoom hloov pauv tas li, kom cov neeg siv khoom tuaj yeem hnov qhov kev sib koom ua ke ntawm thev naus laus zis thiab lub neej, ua rau UWB dhau los ua lo lus txaus los rhuav tshem lub voj voog.
