Xa kufikwa kwintlawulo engeyiyo eyokukhuthazayo, kulula ukucinga ngentlawulo ye-ETC, efezekisa intlawulo ezenzekelayo yebrake yesithuthi ngokusebenzisa ubuchwepheshe bonxibelelwano lwerediyo ye-RFID esebenza kancinci. Ngokusetyenziswa kakuhle kwetekhnoloji ye-UWB, abantu banokuqonda ukungeniswa kwesango kunye nokuncitshiswa ngokuzenzekelayo xa behamba kwi-subway.
Kutshanje, iqonga lekhadi lebhasi laseShenzhen i-“Shenzhen Tong” kunye neHuiting Technology zikhuphe isisombululo sokuhlawula se-UWB “sebhuleki engasebenziyo” yesango le-subway. Ngokusekelwe kwinkqubo ye-RADIO frequency eyinkimbinkimbi ye-multi-chip, isisombululo samkela isisombululo sokhuseleko olupheleleyo se-“eSE+ COS+NFC+BLE” yeHuiting Technology, kwaye sithwala itshiphusi ye-UWB kwindawo yendawo kunye nentengiselwano ekhuselekileyo. Ngefowuni ephathwayo okanye ikhadi lebhasi elifakwe itshiphusi ye-UWB, umsebenzisi unokuzazisa ngokuzenzekelayo xa edlula ibhuleki, aze agqibezele ukuvula kunye nokutsalwa kwemali yokuhlawula ekude.
Ngokutsho kwenkampani, isisombululo sidibanisa i-NFC, i-UWB kunye nezinye iiprotokholi zomqhubi kwi-Bluetooth SoC chip enamandla aphantsi, sinciphisa ubunzima bokuphucula isango ngokuguqulwa kwemodyuli okudibeneyo, kwaye siyahambelana nesango le-NFC. Ngokwesigcawu somfanekiso esisemthethweni, isikhululo sesiseko se-UWB kufuneka sibe sesangweni, kwaye uluhlu lokuchongwa komrhumo wokutsalwa lungaphakathi kwe-1.3m.
Akuqhelekanga ukuba i-UWB (iteknoloji ye-Ultra-wideband) isetyenziswe kwintlawulo engeyiyo eye-inductive. Kwi-Beijing International Urban rail Transit Exhibition ngo-Okthobha ka-2021, i-Shenzhen Tong kunye ne-VIVO nazo zibonise inkqubo yesicelo "sentlawulo yedijithali ye-RMB engeyiyo eye-inductive ye-subway brake" esekelwe kwitekhnoloji ye-UWB, kwaye zafezekisa intlawulo engeyiyo eye-inductive nge-UWB+NFC chip ethwalwa yi-VIVO prototype. Ngaphambili ngo-2020, i-NXP, i-DOCOMO kunye ne-SONY nazo zikhuphe umboniso wezicelo ezintsha ze-UWB kwi-Mall, kubandakanya intlawulo engabonakaliyo, intlawulo yokupaka efikelelekayo, kunye neenkonzo zentengiso ezichanekileyo kunye nokuthengisa.
Ukubeka Indawo Echanekileyo + Intlawulo Engakhathaliyo, i-UWB Ingena Kwintlawulo Yeselfowuni
I-NFC, i-bluetooth, i-ir zizinto eziphambili kwicandelo lesicelo sentlawulo esikufutshane, i-NFC (iteknoloji yonxibelelwano ekufutshane) ngenxa yeempawu zokhuseleko oluphezulu, akufuneki iqhagamshelwe kumbane, umbane kwiimodeli eziqhelekileyo usetyenziswa kakhulu kwiifowuni eziphathwayo, kwiindawo ezifana neJapan neSouth Korea, iifowuni ze-NFC zingasetyenziswa njengoqinisekiso lokungena kwisikhululo seenqwelomoya, uthutho, isitshixo somlindi wokungena kwisakhiwo ikhadi le-IC, ikhadi letyala, ikhadi lokuhlawula, njl.
Itekhnoloji ye-UWB ultra-wideband, eneempawu zempendulo ye-nanosecond ye-ultra-wideband pulse signal (UWB-IR), idityaniswe ne-TOF, i-TDoA/AoA ranging algorithm, kubandakanya izigcawu zomgca wokubona (LoS) kunye nezigcawu ezingezizo zomgca wokubona (nLoS) zinokufikelela kubuchule bokubeka i-centimeter-level. Kumanqaku adlulileyo, i-Iot Media ingenise usetyenziso kwindawo echanekileyo yangaphakathi, izitshixo zemoto zedijithali kunye nezinye iinkalo ngokweenkcukacha. I-UWB ineempawu zokuchaneka okuphezulu kwendawo, izinga eliphezulu lokudlulisela, ukumelana nokuphazamiseka kwesignali kunye nokubanjwa, nto leyo eyinika iingenelo zendalo ekusebenziseni intlawulo engeyiyo i-inductive.
Umgaqo wokuhlawula ngokungakhathaliyo kwisango lendlela ephantsi komhlaba ulula kakhulu. Iifowuni eziphathwayo kunye namakhadi ebhasi anomsebenzi we-UWB anokuthathwa njengethegi yeselula ye-UWB. Xa isikhululo sesiseko sibona indawo yethegi, siya kuyitshixa kwaye siyilandele ngoko nangoko. I-UWB kunye ne-eSE security chip + inhlanganisela ye-NFC ukufezekisa intlawulo ekhuselekileyo ye-encryption kwinqanaba lezemali.
Usetyenziso lwe-NFC+UWB, olunye usetyenziso oludumileyo sisitshixo semoto esibonakalayo. Kwicandelo lezitshixo zedijithali zeemoto, ezinye iimodeli eziphakathi neziphezulu zeBMW, iNIO, iVolkswagen kunye nezinye iimpawu ziye zamkela inkqubo ethi “BLE+UWB+NFC”. I-Bluetooth remote sensing ivuselela i-UWB ukuze idlulisele idatha ngokubethela, i-UWB isetyenziselwa ukuqonda ngokuchanekileyo, kwaye i-NFC isetyenziswa njengesicwangciso sokugcina ukusilela kombane ukufikelela kulawulo lokuvula phantsi kweemeko ezahlukeneyo zomgama kunye nokunikezelwa kombane.
Ukwandiswa kwesithuba, impumelelo okanye ukusilela kwe-UWB kuxhomekeke kwicala labathengi
Ukongeza ekubekeni ngokuchanekileyo, i-UWB ikwaphawuleka kakhulu ekudlulisweni kwedatha ngesantya esiphezulu kumgama omfutshane. Nangona kunjalo, kwicandelo le-intanethi yezinto zoshishino, ngenxa yokungeniswa ngokukhawuleza kunye nokuthandwa kwemarike ye-wi-fi, iZigbee, iBLE kunye neminye imigangatho yeprotocol, i-UWB isenokukwazi ukubeka ngaphakathi ngokuchanekileyo, ngoko ke imfuno kwimarike ye-B-end ikwizigidi kuphela, ezisasazeke kakhulu. Imarike yesitokhwe enjalo kunzima kubavelisi beetships ukufezekisa utyalo-mali oluzinzileyo.
Iqhutywa yimfuno yeshishini, i-C-end consumer Internet of Things iye yaba yindawo ephambili yemfazwe ezingqondweni zabavelisi be-UWB. I-electronics yabathengi, ii-smart tag, ikhaya elikrelekrele, iimoto ezikrelekrele, kunye nentlawulo ekhuselekileyo ziye zaba ziimeko eziphambili zophando nophuhliso lwe-NXP, Qorvo, ST kunye namanye amashishini. Umzekelo, kwicandelo lolawulo lokufikelela olungenamvakalelo, intlawulo engabonakaliyo kunye nekhaya elikrelekrele, i-UWB inokwenza ngokwezifiso iiSetingi zasekhaya ngokweenkcukacha ze-ID. Kwi-electronics yabathengi, iifowuni ze-UWB kunye nezixhobo zazo zingasetyenziselwa indawo yangaphakathi, ukulandelela izilwanyana zasekhaya, kunye nokudluliselwa kwedatha ngokukhawuleza.
UChen Zhenqi, i-CEO yeNewwick, inkampani yasekhaya ye-UWB chips, wakha wathi “iifowuni ezikrelekrele kunye neemoto, njengezona terminals zibalulekileyo neziphambili kwi-intanethi enkulu kuyo yonke into ezayo, ziya kuba yimarike enkulu yetekhnoloji ye-UWB”. I-ABI Research iqikelele ukuba ii-smartphones ezisebenzisa i-UWB ezizigidi ezingama-520 ziya kuthunyelwa ngo-2025, kwaye i-32.5% yazo iya kuhlanganiswa ne-UWB. Oku kunika abavelisi be-UWB okuninzi abanokucinga ngako, kwaye iQorvo ilindele ukuba ukuthunyelwa kwe-UWB kuhambelane nokusetyenziswa kweBluetooth kwixesha elizayo.
Nangona ulindelo lokuthunyelwa kweetshiphusi lulungile, uQorvo uthe owona mceli mngeni mkhulu kushishino lwe-UWB kukungabikho kwekhonkco elipheleleyo lemizi-mveliso lokulixhasa. Amashishini eetshiphusi aphezulu e-UWB aquka i-NXP, iQorvo, i-ST, i-Apple, i-Newcore, i-Chixin Semiconductor, i-Hanwei Microelectronics kunye namanye amashishini, ngelixa i-middle stream inabavelisi bokudibanisa iimodyuli, abavelisi bezikhululo zeeleyibhile, iifowuni eziphathwayo kunye nabavelisi bezixhobo ze-peripheral.
Ngokukhawuleza inkampani ibandakanyeka kuphuhliso lwe-chip ye-UWB, uninzi lwe-"MaoJian", kodwa isenokungabikho komgangatho we-chip, kushishino kunzima ukwenza imigangatho yoqhagamshelwano oludibeneyo njenge-bluetooth, abathengisi abaphakathi nabasezantsi kufuneka basebenzise imeko yesicelo esongezelelweyo, nto leyo ebangela ukuba umsebenzisi asebenzise i-UWB rhoqo, ukusuka kwinqanaba leziphumo, impumelelo okanye ukungaphumeleli kwemarike ye-UWB kubonakala ngathi kuxhomekeke kubathengi.
Ekugqibeleni
Ukukhuthazwa kwentlawulo engenabungozi ye-UWB, kwelinye icala, kuxhomekeke ekubeni iifowuni eziphathwayo ezine-UWB eyakhelwe ngaphakathi zinokuthandwa na kwimarike. Okwangoku, ziimodeli ezithile ze-Apple, Samsung, Xiaomi kunye ne-VIVO ezixhasa i-UWB, kwaye i-OPPO ikwaqalisa inkqubo "yoqhagamshelo oluneqhosha elinye" lwe-UWB mobile phone case, ngoko ke ukuthandwa kwemodeli kunye noluntu kusancinci. Kusafuneka kubonwe ukuba ingaba ingakwazi na ukufikelela kudumo lwe-NFC kwiifowuni eziphathwayo, kwaye ukufikelela kubungakanani be-bluetooth kusengumbono. Kodwa xa sijonga "ukungena" kwabavelisi beefowuni bangoku, usuku lwe-UWB njengomgangatho aluyi kuba kude kakhulu.
Kwelinye icala, kukho izinto ezintsha ezingapheliyo zeemeko zokuphela kwabathengi ezihlala ziphezulu. I-UWB yokulandelela abathengi, indawo, ulawulo olukude, intlawulo iyandiswa ngabavelisi be-midstream: I-Airtag ye-Apple, i-One Finger ye-Xiaomi, izitshixo zemoto zedijithali ze-NiO, indawo yokubeka uphawu lwe-fusion ye-Huawei ngaphakathi, i-radar ye-ultra-wideband ye-NXP, intlawulo ye-metro ye-Huidong… Kuphela ziinkqubo ezahlukeneyo ezintsha zokwandisa ukuphindaphindeka kokufikelela kwabathengi ezihlala zitshintsha, ukuze abathengi bazive ukuhlanganiswa okungenamda kwetekhnoloji nobomi, okwenza i-UWB ibe ligama elaneleyo lokuphula isangqa.
