Uma kuziwa ekukhokheni okungashintshiwe, kulula ukucabanga ngenkokhelo ye-ETC, eqaphela ukukhokha okuzenzakalelayo kwebhuleki lemoto ngobuchwepheshe bokuxhumana befrikhwensi yomsakazo we-RFID. Ngokusetshenziswa okuhle kobuchwepheshe be-UWB, abantu bangakwazi futhi ukubona ukungeniswa kwesango nokubanjwa okuzenzakalelayo lapho behamba esitimeleni.
Muva nje, inkundla yekhadi lebhasi lase-Shenzhen "i-Shenzhen Tong" kanye ne-Huiting Technology ngokuhlanganyela bakhiphe isisombululo sokukhokha se-UWB "sebhuleki elingaxhunyiwe ku-inthanethi elingenayo inductive" lesango lesitimela esingaphansi komhlaba. Ngokusekelwe ohlelweni lwefrikhwensi ye-RADIO enama-chip amaningi, isisombululo samukela isixazululo esigcwele sokuphepha se-"eSE+ COS+NFC+BLE" se-Huiting Technology, futhi siphethe i-chip ye-UWB yendawo yendawo kanye nokwenza okuphephile. Ngomakhalekhukhwini noma ikhadi lebhasi elishumekwe ne-UWB chip, umsebenzisi angakwazi ukuzibonakalisa ngokuzenzekelayo lapho edlula ibhuleki, futhi aqedele ukuvuleka nokudonswa kweremothi yemali yokugibela.
Ngokusho kwenkampani, isisombululo sihlanganisa i-NFC, i-UWB nezinye izimiso zomshayeli ku-chip ye-Bluetooth SoC enamandla aphansi, kunciphisa ubunzima bokuthuthukisa isango ngokuguqulwa okuhlanganisiwe kwe-modular, futhi kuyahambisana nesango le-NFC. Ngokwesithombe esisemthethweni, isizinda sesiteshi sase-UWB kufanele sibe sesangweni, futhi ububanzi bokuhlonza imali ebanjwayo bungaphakathi kuka-1.3m.
Akuvamile ukuthi i-UWB (Ubuchwepheshe be-Ultra-wideband) isetshenziswe ekukhokheni okungashintshisi. Embukisweni we-Beijing International Urban Rail Transit Exhibition ngo-Okthoba 2021, i-Shenzhen Tong kanye ne-VIVO baphinde babonisa uhlelo lokusebenzisa “inkokhelo yedijithali ye-RMB engashintshisi ye-RMB yamabhuleki esitimela esingaphansi komhlaba” okusekelwe kubuchwepheshe be-UWB, futhi bathola ukukhokha okungashintshisi nge-chip ye-UWB+NFC. nge-VIVO prototype. Ngaphambilini ngo-2020, i-NXP, i-DOCOMO kanye ne-SONY baphinde bakhipha ukuboniswa kwezicelo ezintsha zokuthengisa ze-UWB enxanxatheleni yezitolo, okuhlanganisa inkokhelo enganaki, inkokhelo efinyelelekayo yokupaka, kanye nezinsizakalo zokukhangisa nezimakethe ezinembayo.
Ukuma Okuqondile + Inkokhelo Engazweli, I-UWB Ifaka Inkokhelo Yeselula
I-NFC, i-bluetooth, i-ir iyinkambinkimbi emkhakheni wesicelo sokukhokha sensimu eseduze, i-NFC (eduze nobuchwepheshe bokuxhumana bensimu) ngenxa yezimpawu zokuvikeleka okuphezulu, akudingeki ukuthi ixhunywe kugesi, yamanje kumamodeli ajwayelekile asetshenziswa kabanzi umakhalekhukhwini, ezindaweni ezifana ne-Japan ne-South Korea, izingcingo eziphathwayo ze-NFC zingasetshenziswa njengokuqinisekisa ukugibela esikhumulweni sezindiza, ezokuthutha, ukhiye wonogada bokungena ekhadini le-IC, ikhadi lesikweletu, ikhadi lokukhokha, njll.
Ubuchwepheshe be-UWB ultra-wideband, enezici zokuphendula ze-ultra-wideband pulse (UWB-IR) nanosecond, kuhlanganiswe ne-TOF, i-TDoA/AoA esukela ku-algorithm, okuhlanganisa izigcawu zomugqa wokubona (LoS) kanye ne-non-line-of-sight (nLoS ) izigcawu zingafinyelela ukunemba kokuma kwezinga lesentimitha. Ezihlokweni ezedlule, i-Iot Media yethule uhlelo lokusebenza endaweni enembile yasendlini, okhiye bemoto yedijithali neminye imikhakha ngokuningiliziwe. I-UWB inezici zokunemba kokuma okuphezulu, izinga eliphezulu lokudlulisela, ukumelana nokuphazamiseka kwesignali kanye nokucasha, okuyinikeza izinzuzo zemvelo ekusetshenzisweni kwenkokhelo engenzi inzuzo.
Umgomo wokukhokha okungenazwelo kwesango lesitimela ulula kakhulu. Omakhalekhukhwini namakhadi ebhasi anomsebenzi we-UWB angathathwa njengethegi ye-UWB yeselula. Lapho isiteshi sesisekelo sithola ukuma kwendawo kwethegi, sizokhiya ngokushesha bese siyilandela. Inhlanganisela ye-UWB ne-eSE security chip +NFC ukuze kuzuzwe inkokhelo yokubethela evikelekile yezinga lezezimali.
Uhlelo lokusebenza lwe-NFC+UWB, olunye uhlelo lokusebenza oludumile ukhiye obonakalayo wemoto. Emkhakheni wokhiye bedijithali bezimoto, ezinye izinhlobo ezimaphakathi neziphezulu ze-BMW, i-NIO, i-Volkswagen nezinye izinhlobo zamukele uhlelo lwe-“BLE+UWB+NFC”. Ukuzwa okukude kwe-Bluetooth kuvusa i-UWB ukuze kudluliselwe ukubethela kwedatha, i-UWB isetshenziselwa ukubona okunembile okusukela, futhi i-NFC isetshenziswa njengesikimu esiyisipele sokuhluleka kwamandla ukuzuza ukulawula kokuvula ngaphansi kwebanga elihlukahlukene nezimo zokunikezwa kwamandla.
Isikhala Sokunyuswa kwe-UWB, Impumelelo noma Ukwehluleka kuncike Ohlangothini Lomthengi
Ngaphezu kokuma okunembile, i-UWB iphinde iphawuleke ekudluliselweni kwedatha ebangeni elifushane ngesivinini esikhulu. Kodwa-ke, emkhakheni we-inthanethi yezimboni Yezinto, ngenxa yokwethulwa okusheshayo nokuthandwa kwemakethe kwe-wi-fi, i-Zigbee, i-BLE namanye amazinga omthetho, i-UWB isakwazi ukubeka indawo yasendlini enembayo, ngakho-ke isidingo ku-B- imakethe yokugcina iyizigidi kuphela, ehlakazekile. Imakethe yamasheya enjalo inzima kubakhiqizi be-chip ukufeza ukutshalwa kwezimali okusimeme.
Iqhutshwa yisidingo semboni, i-C-end yabathengi be-inthanethi Yezinto isiphenduke inkundla yempi eyinhloko ezingqondweni zabakhiqizi be-UWB. Ama-electronics abathengi, amathegi ahlakaniphile, ikhaya elihlakaniphile, izimoto ezihlakaniphile, nokukhokha okuvikelekile sekube yizimo eziyinhloko zocwaningo nezokuthuthukiswa kwe-NXP, Qorvo, ST kanye namanye amabhizinisi. Isibonelo, emikhakheni yokulawula ukufinyelela okungenazwelo, inkokhelo enganaki kanye nekhaya elihlakaniphile, i-UWB ingenza ngendlela oyifisayo Izilungiselelo zekhaya ngokusho kolwazi lwe-ID. Kuma-electronics abathengi, amafoni e-UWB kanye nezingxenyekazi zekhompuyutha zabo zingasetshenziselwa indawo yasendlini, ukulandelela izilwane ezifuywayo, kanye nokudluliswa kwedatha okusheshayo.
U-Chen Zhenqi, oyi-CEO yakwa-Newwick, inkampani yasekhaya yama-chip e-UWB, wake wathi “amafoni ahlakaniphile nezimoto, njengamatheminali ahlakaniphile futhi abalulekile esikhathini esizayo esinenqwaba ye-inthanethi yazo zonke izinto, kuzoba futhi imakethe enkulu kunazo zonke engaba khona yobuchwepheshe be-UWB”. Ucwaningo lwe-ABI lubikezele ukuthi ama-smartphones anikwe amandla e-UWB ayizigidi ezingama-520 azothunyelwa ngo-2025, futhi ama-32.5% awo azohlanganiswa ne-UWB. Lokhu kunikeza abakhiqizi be-UWB okuningi abangacabanga ngakho, futhi u-Qorvo ulindele ukuthunyelwa kwe-UWB ukufanisa ukusetshenziswa kwe-Bluetooth esikhathini esizayo.
Nakuba okulindelwe ukuthunyelwa kwe-chip kukuhle, u-Qorvo uthe inselele enkulu embonini ye-UWB ukuntuleka kochungechunge lwezimboni oluphelele lokuyisekela. Amabhizinisi ama-chip e-UWB aphezulu ahlanganisa i-NXP, i-Qorvo, i-ST, i-Apple, i-Newcore, i-Chixin Semiconductor, i-Hanwei Microelectronics namanye amabhizinisi, kuyilapho ukusakazwa okuphakathi kunabakhiqizi bokuhlanganisa amamojula, abakhiqizi beziteshi eziyisisekelo zamalebula, omakhalekhukhwini kanye nabakhiqizi bezingxenyekazi zekhompyutha.
Ngokushesha inkampani ibambe iqhaza ekuthuthukisweni kwe-chip ye-UWB, inani elikhulu le- "MaoJian", kodwa isengakwazi ukuntuleka kokumiswa kwe-chip, imboni inzima ukwakha amazinga okuxhumana ahlanganisiwe njenge-bluetooth, ukufinyelela okuphakathi nendawo okuphansi kwesidingo sabathengisi beketango lezimboni. ukusebenzisa icala lesicelo esiningi, qalisa umsebenzisi emsebenzini we-UWB imvamisa yokusetshenziswa, kusukela endaweni yemiphumela, Impumelelo noma ukwehluleka kwemakethe ye-UWB kubonakala kuphumule ohlangothini lwabathengi.
Ekupheleni
Ukukhuthazwa kwenkokhelo engenazwelo ye-UWB, ngakolunye uhlangothi, kuncike ekutheni omakhalekhukhwini abanomsebenzi we-UWB eyakhelwe ngaphakathi bangasakazwa yini emakethe. Njengamanje, amamodeli athile kuphela we-Apple, Samsung, Xiaomi kanye ne-VIVO asekela i-UWB, kanye ne-OPPO futhi yethula uhlelo “lokuxhuma inkinobho eyodwa” lwekesi lefoni yeselula ye-UWB, ngakho ukuthandwa kwemodeli nomphakathi kusekulinganiselwe. Kusazobonakala ukuthi ingakwazi yini ukuhambisana nokuduma kwe-NFC komakhalekhukhwini, futhi ukufinyelela kusayizi we-bluetooth kusengumbono. Kodwa uma sibheka “ekungeneni” kwabakhiqizi bamanje bezingcingo, usuku lwe-UWB njengendinganiso ngeke lube kude kakhulu.
Ngakolunye uhlangothi, kunokuqanjwa okusha okungapheli kwezimo zokuphela kwabathengi ezivame kakhulu. I-UWB yokulandela umkhondo wabathengi, indawo, isilawuli kude, inkokhelo inwetshwa abakhiqizi abamaphakathi: i-Apple's Airtag, i-One Finger ye-Xiaomi, okhiye bemoto yedijithali ye-NiO, ukuma kwesignali ye-Huawei yasendlini, irada ye-NXP ye-ultra-wideband, inkokhelo kamasipala we-Huidong... Izinhlobonhlobo kuphela izinhlelo ezintsha zokwandisa imvamisa yokufinyelela kwabathengi zilokhu zishintsha, ukuze abathengi bakwazi ukuzwa ukuhlanganiswa okungenamingcele kobuchwepheshe nokuphila, okwenza i-UWB ibe igama elanele ukuphula umbuthano.
