Kana zvasvika kune isiri-inductive kubhadhara, zviri nyore kufunga nezve ETC kubhadhara, iyo inoziva kubhadhara otomatiki kwemabhureki emotokari kuburikidza nesemi-inoshanda RFID radio frequency kutaurirana tekinoroji.Nekushandiswa kwakanaka kweUWB tekinoroji, vanhu vanogona zvakare kuona gedhi induction uye otomatiki kubviswa kana vachifamba munzira yepasi.
Munguva pfupi yapfuura, Shenzhen bhazi kadhi chikuva "Shenzhen Tong" uye Huiting Technology vakabatana vakaburitsa UWB kubhadhara mhinduro ye "non-inductive off-line brake" ye subway gedhi.Kubva pane yakawanda-chip yakaoma RADIO frequency system, mhinduro inotora yakazara stack yekuchengetedza mhinduro ye "eSE + COS + NFC + BLE" yeHuiting Technology, uye inotakura UWB chip yenzvimbo nenzvimbo uye yakachengeteka kutengeserana.Kuburikidza nenharembozha kana kadhi rebhazi rakaiswa chip yeUWB, mushandisi anogona kuzvizivisa oga paanenge achipfuura bhureki, uye opedzisa kuvhura uye kubvisa mari yekubhadhara.
Sekureva kwekambani, mhinduro inobatanidza NFC, UWB uye mamwe madhiraivha mapuroteni mune yakaderera simba Bluetooth SoC chip, inoderedza kuoma kwekusimudzira gedhi kuburikidza neyakasanganiswa modular shanduko, uye inowirirana neiyo NFC gedhi.Zvinoenderana neiyo yepamutemo pikicha chiitiko, iyo UWB base station inofanirwa kunge iri pagedhi, uye huwandu hwekuzivikanwa hwemubhadharo wekubvisa uri mukati me1.3m.
Hazvishamisi kuti UWB (Ultra-wideband tekinoroji) ishandiswe mukubhadhara kusiri-inductive.PaBeijing International Urban rail Transit Exhibition muna Gumiguru 2021, Shenzhen Tong neVIVO vakaratidzawo chirongwa chekushandisa che "non-inductive digital RMB kubhadhara kwe subway brake" zvichienderana neUWB tekinoroji, uye vakaziva kubhadhara kusiri-inductive kuburikidza neUWB+NFC chip yakatakurwa. neVIVO prototype.Pakutanga muna 2020, NXP, DOCOMO neSONY zvakare yakaburitsa ratidziro yezvitsva zvekutengesa zveUWB muMall, kusanganisira kubhadhara kusinganzwisisike, kubhadhara kunowanikwa kwekupaka, uye kushambadzira chaiko uye masevhisi ekushambadzira.
Precise Positioning + Insensitive Payment, UWB Inopinda Mobile Payment
NFC, bluetooth, ir iri mainstream mumunda wepadhuze yekubhadhara munda application, NFC (padhuze nefield communication tekinoroji) nekuda kwehunhu hwekuchengetedzeka kwakanyanya, haidi kubatanidzwa kune magetsi, iyo iripo mumamodhi akajairika anoshandiswa zvakanyanya mukati. nharembozha, munzvimbo dzakaita seJapan neSouth Korea, NFC nharembozha dzinogona kushandiswa senhandare yendege yekumisikidza, chekufambisa, chivakwa chekuvakisa kiyi IC kadhi, kadhi rechikwereti, kadhi rekubhadhara, nezvimwe.
UWB Ultra-wideband tekinoroji, ine Ultra-wideband pulse siginecha (UWB-IR) nanosecond mhinduro maitiro, akasanganiswa neTOF, TDoA/AoA inotangira algorithm, inosanganisira mutsara wekuona (LoS) zviratidziro uye isiri-mutsara-wekuona (nLoS ) zviratidziro zvinogona kuwana centimita-level yekumisikidza kwayo.Muzvinyorwa zvakapfuura, Iot Media yakaunza iyo application mune yemukati chaiyo chinzvimbo, makiyi emota yedhijitari uye mamwe minda zvakadzama.UWB ine hunhu hwekurongeka kwepamusoro, mwero wekutapurirana, chiratidzo chekuvhiringidza kuramba uye kupindira, izvo zvinozvipa mabhenefiti echisikigo mukushandiswa kwekubhadhara kusiri-inductive.
Nheyo ye subway gedhi kusanzwa kubhadhara kuri nyore.Nharembozha uye makadhi ebhazi ane UWB basa anogona kutorwa senge yeUWB nharembozha.Kana base chiteshi chaona nzvimbo yeti tag, inobva yavhara nekuitevera.UWB uye eSE chengetedzo chip + NFC musanganiswa kuti uwane chiyero chemari chakachengeteka chekubhadhara kubhadhara.
NFC + UWB application, imwe yakakurumbira application ndiyo mota chaiyo kiyi.Mumunda wemakiyi emagetsi edhijitari, mamwe epakati uye epamusoro-ekupedzisira emhando dzeBMW, NIO, Volkswagen nemamwe mabhureki atora chirongwa che "BLE + UWB + NFC".Bluetooth kure sensing inomutsa UWB yekutepfenyura data, UWB inoshandiswa kune chaiyo kubva pakuona, uye NFC inoshandiswa senge backup chirongwa chekutadza kwemagetsi kuzadzisa kuvhura kudzora pasi pechinhambwe chakasiyana uye magetsi emagetsi.
UWB Kuwedzera Nzvimbo, Kubudirira kana Kutadza kunoenderana nedivi reVatengi
Pamusoro pekumisikidza kwakaringana, UWB zvakare inoshamisa mune ipfupi-kure-kumhanya kufambisa data.Nekudaro, mumunda weindasitiri Internet yeZvinhu, nekuda kwekukurumidza kusuma uye kufarirwa kwemusika kwewi-fi, Zigbee, BLE uye mamwe maprotocol standards, UWB ichiri kukwanisa kukwira-chaiyo nzvimbo yemukati, saka kudiwa muB- kuguma kwemusika kunongova mumamiriyoni, ayo akapararira.Musika wemari wakadaro wakaoma kune vanogadzira chip kuti vawane mari yakachengeteka.
Inotungamirwa nekudiwa kwemaindasitiri, iyo C-yekupedzisira mutengi Internet yeZvinhu yave iyo huru nhandare yehondo mupfungwa dzevagadziri veUWB.Zvemagetsi zvevatengi, ma tag akangwara, imba yakangwara, mota dzakangwara, uye kubhadhara kwakachengeteka zvave iwo akakosha ekutsvagisa uye kusimudzira mamiriro eNXP, Qorvo, ST uye mamwe mabhizinesi.Semuenzaniso, muminda yekusakendenga yekuwana kutonga, kubhadhara kusinganzwi uye smart imba, UWB inogona kugadzirisa imba Zvirongwa zvinoenderana neruzivo rweID.Mumagetsi evatengi, nhare dzeUWB nehardware yavo inogona kushandiswa munzvimbo yemukati, kutevedza mhuka dzinovaraidza, uye kukurumidza kutumira data.
Chen Zhenqi, CEO weNewwick, kambani yemumba yeUWB chip, akambotaura kuti "mafoni akangwara nemota, seakanyanya kukosha uye akangwara materminal mune ramangwana ruzhinji Internet yezvese, ichavewo musika mukuru ungangoita weUWB tekinoroji".ABI Tsvagiridzo yakafanotaura kuti 520 miriyoni UWB inogonesa mafoni achatumirwa panosvika 2025, uye 32.5% yawo ichabatanidzwa neUWB.Izvi zvinopa vagadziri veUWB zvakawanda zvekufunga nezvazvo, uye Qorvo inotarisira kuti UWB inotumirwa ienderane nekushandiswa kweBluetooth mune ramangwana.
Nepo tarisiro yekutakura chip yakanaka, Qorvo akati dambudziko guru reUWB indasitiri kushaikwa kweketani yakazara yemaindasitiri kuti itsigire.UWB's upstream chip enterprises anosanganisira NXP, Qorvo, ST, Apple, Newcore, Chixin Semiconductor, Hanwei Microelectronics nemamwe mabhizinesi, nepo rukova rwepakati rune vanogadzira mamodule ekubatanidza, vagadziri vezviteshi zvelabel, nharembozha uye vanogadzira hardware.
Nekukurumidza kambani iri kuita kugadzirwa kweUWB chip, huwandu hukuru hwe "MaoJian", asi inogona kuramba ichishaikwa yekumisikidza chip, indasitiri yakaoma kuumba yakabatana yekubatanidza zviyero sebluetooth, yepakati uye yakaderera kusvika kweiyo maindasitiri cheni vatengesi vanoda. kushandisa yakawanda application kesi, konzeresa mushandisi pane basa reUWB frequency yekushandiswa, kubva padanho remhedzisiro, Kubudirira kana kukundikana kwemusika weUWB kunoratidzika kunge kunozorora padivi revatengi.
Pakupedzisira
Kukwidziridzwa kweUWB kusanzwa kubhadhara, kune rumwe rutivi, kunoenderana nekuti nharembozha dzine yakavakirwa-mukati UWB basa dzinogona kufarirwa pamusika.Parizvino, mamwe mamodheru eApple, Samsung, Xiaomi uye VIVO anotsigira UWB, uye OPPO inotangisawo "bhatani-rimwe rekubatanidza" chirongwa cheUWB mbozha mbozha kesi, saka kufarirwa kwemuenzaniso uye veruzhinji kuchiri kushoma.Izvo zvinoramba zvichionekwa kana zvichigona kubata nekuzivikanwa kweNFC munharembozha, uye kusvika saizi yebluetooth ichiri chiono.Asi tichifunga kubva ku "roll-in" yevagadziri vefoni ikozvino, zuva reUWB seyakajairwa harizove kure zvakanyanya.
Kune rimwe divi, kune kusingaperi hunyanzvi hwepamusoro frequency mutengi kupera kwezviitiko.UWB yekutsvagisa vatengi, nzvimbo, kudzora kure, kubhadhara kuri kuwedzerwa nevagadziri vepakati: Apple's Airtag, Xiaomi's One Finger, NiO's digital car keys, Huawei's fusion sign indoor positioning, NXP's Ultra-wideband radar, Huidong's metro kubhadhara... zvirongwa zvitsva zvekuwedzera kuwanda kwekuwanikidzwa kwevatengi zvinoramba zvichichinja, kuitira kuti vatengi vanzwe kusanganisa kusingagumi kwehunyanzvi uye hupenyu, zvichiita kuti UWB ive izwi rakakwana kutyora denderedzwa.
