Kana zvasvika pakubhadhara kusiri kweinductive, zviri nyore kufunga nezve ETC payment, iyo inoita kuti mota ibhadhare otomatiki kuburikidza ne semi-active RFID radio frequency communication technology. Nekushandisa kwakanaka kwetekinoroji yeUWB, vanhu vanogonawo kuziva gate induction uye automatic deduction pavanenge vachifamba muchitima chepasi pevhu.
Munguva pfupi yapfuura, puratifomu yemakadhi emabhazi eShenzhen "Shenzhen Tong" neHuiting Technology vakaburitsa pamwe chete mhinduro yekubhadhara yeUWB ye "non-inductive off-line brake" yegedhi repasi pevhu. Zvichibva pasystem yeRADIO frequency system ine machipisi akawanda, mhinduro iyi inoshandisa mhinduro yekuchengetedza yakazara ye "eSE+ COS+NFC+BLE" yeHuiting Technology, uye inotakura chip yeUWB yenzvimbo uye kutengeserana kwakachengeteka. Kuburikidza nefoni mbozha kana kadhi rebhazi rakabatanidzwa neUWB chip, mushandisi anogona kuzvizivisa ega paanopfuura brake, uye kupedzisa kuvhura kure uye kubvisa mari yekufambisa.
Sekureva kwekambani, mhinduro iyi inobatanidza NFC, UWB nedzimwe nzira dzekutyaira muBluetooth SoC chip ine simba shoma, inoderedza kuoma kwekuvandudza gedhi kuburikidza nekuchinja kwemodular kwakabatanidzwa, uye inoenderana neGETI reNFC. Sekureva kwemufananidzo wepamutemo, chiteshi cheUWB chinofanira kunge chiri pagedhi, uye huwandu hwekuzivikanwa kwemari yekuderedzwa iri mukati me1.3m.
Hazvishamisi kuti UWB (Ultra-wideband technology) ishandiswe mukubhadhara kusingainductive. PaBeijing International Urban Rail Transit Exhibition muna Gumiguru 2021, Shenzhen Tong neVIVO vakaratidzawo hurongwa hwekushandisa "kubhadhara kweRMB yedhijitari kusingainductive yechitima chepasi pevhu" zvichibva pahunyanzvi hweUWB, uye vakabhadhara kusingainductive kuburikidza neUWB+NFC chip inotakurwa neVIVO prototype. Pakutanga kwa2020, NXP, DOCOMO neSONY vakaburitsawo kuratidzwa kwezvishandiso zvitsva zveUWB muMall, kusanganisira kubhadhara kusinganzwisisiki, kubhadhara kwekupaka kuri nyore, uye masevhisi ekushambadzira akanyatsojeka.
Kuisa Nzvimbo Yakakodzera + Kubhadhara Kusina Kufunganya, UWB Yapinda Mukubhadhara Kwefoni
NFC, bluetooth, ir inyanzvi mukushandisa payment application iri pedyo nefield, NFC (near field communication technology) nekuda kwehunhu hwayo hwekuchengetedza kwakanyanya, haifanirwe kubatanidzwa kumagetsi, magetsi ari mumamodheru anoshandiswa zvakanyanya mumafoni, munzvimbo dzakadai seJapan neSouth Korea, mafoni eNFC anogona kushandiswa senzira yekusimbisa bhodhi rendege, kutakurwa, key yekupinda muchivako IC card, credit card, payment card, nezvimwewo.
Tekinoroji yeUWB ultra-wideband, ine hunhu hwe ultra-wideband pulse signal (UWB-IR) nanosecond response, pamwe chete neTOF, TDoA/AoA ranging algorithm, kusanganisira line of sight (LoS) scenes uye non-line-of-sight (nLoS) scenes zvinogona kuwana centimeter-level positioning accuracy. Muzvinyorwa zvakapfuura, Iot Media yakaunza application mu indoor precise positioning, digital car keys nedzimwe nzvimbo zvakadzama. UWB ine hunhu hwe high positioning accuracy, high transmission rate, signal interference resistance uye interception, izvo zvinoipa mabhenefiti echisikigo mukushandisa non-inductive payment.
Nheyo yekubhadhara isina hanya negedhi repasi pevhu iri nyore kwazvo. Nharembozha nemakadhi emabhazi ane basa reUWB zvinogona kuonekwa seUWB mobile tag. Kana chiteshi chepasi chikaona nzvimbo yetag, chinoivhara nekuitevera. UWB ne eSE security chip +NFC musanganiswa kuti uwane muripo wekuchengetedza encryption wepamusoro-soro.
Chishandiso cheNFC+UWB, chimwe chishandiso chakakurumbira ikey yemotokari chaiyo. Munyaya yemakiyi edhijitari emotokari, mamwe mamodheru epakati neepamusoro eBMW, NIO, Volkswagen nedzimwe mhando dzakashandisa chirongwa che "BLE+UWB+NFC". Bluetooth remote sensing inomutsa UWB kuti itumirwe data encryption, UWB inoshandiswa kuona data rankings nemazvo, uye NFC inoshandiswa senzira yekuchengetedza magetsi kuti akwanise kuvhura pasi pemamiriro akasiyana-siyana edhijitari uye magetsi.
Kuwedzera kweUWB Nzvimbo, Kubudirira kana Kukundikana Zvinoenderana neRutivi rweVatengi
Pamusoro pekuiswa kwakarurama, UWB inoshamisawo mukutumira data nekukurumidza daro pfupi. Zvisinei, mumunda weInternet of Things yemaindasitiri, nekuda kwekukurumidzira kukuru uye kufarirwa kweWi-Fi, Zigbee, BLE nedzimwe protocol standards pamusika, UWB ichiri kukwanisa kuisa data rakarurama mukati meimba, saka kudiwa kweB-end musika kuri mumamiriyoni chete, ayo akapararira zvishoma. Musika wemasheya wakadaro unonetsa vagadziri vemachipisi kuti vawane mari inochengetedza nharaunda.
Zvichitungamirirwa nekudiwa kwemaindasitiri, C-end consumer Internet of Things yave nzvimbo huru yehondo mupfungwa dzevagadziri veUWB. Magetsi emagetsi evatengi, ma smart tag, dzimba dzakangwara, mota dzakangwara, uye muripo wakachengeteka zvave zvinhu zvakakosha pakutsvaga nekusimudzira NXP, Qorvo, ST nedzimwe makambani. Semuenzaniso, muminda yekudzora kupinda muchivande, kubhadhara kusinganzwisisike uye dzimba dzakangwara, UWB inogona kugadzirisa Magadzirirwo emba zvichienderana neruzivo rweID. Mumagetsi evatengi, mafoni eUWB nemidziyo yavo zvinogona kushandiswa munzvimbo yemukati, kuteedzera mhuka dzinovaraidza, uye kutumira data nekukurumidza.
Chen Zhenqi, CEO weNewwick, kambani yeUWB chip yemuno, akambotaura kuti "mafoni nemota, senzvimbo dzakakosha uye dzakangwara mune ramangwana reInternet pane zvese, zvichavewo musika mukuru weUWB tekinoroji". ABI Research yakafanotaura kuti mafoni e520 miriyoni ane UWB achatumirwa panosvika 2025, uye 32.5% awo achabatanidzwa neUWB. Izvi zvinopa vagadziri veUWB zvakawanda zvekufunga nezvazvo, uye Qorvo inotarisira kuti kutumirwa kweUWB kuenderane nekushandiswa kweBluetooth mune ramangwana.
Kunyange hazvo tarisiro yekutumirwa kwemachipisi yakanaka, Qorvo akati dambudziko guru kuindasitiri yeUWB kushaya cheni yakazara yemaindasitiri inoitsigira. Makambani eUWB anotungamira machipisi anosanganisira NXP, Qorvo, ST, Apple, Newcore, Chixin Semiconductor, Hanwei Microelectronics nemamwe makambani, nepo middle stream ine vagadziri vemamodule integration, vagadziri vema label base station, nharembozha uye vagadziri vemidziyo yekunze.
Kambani iri kukurumidza kugadzira chip yeUWB, ine huwandu hwakawanda hwe "MaoJian", asi ichiri kushaya standardization ye chip, indasitiri yakaoma kugadzira standards dzakabatana dzekubatanidza senge bluetooth, vatengesi vepakati nepazasi vemaindasitiri vanofanirwa kushandisa kesi yakawanda yekushandisa, zvichikonzera mushandisi pabasa reUWB frequency yekushandiswa, kubva pamhedzisiro, kubudirira kana kukundikana kwemusika weUWB kunoita sekunge kuri kudivi revatengi.
Pakupedzisira
Kukwidziridzwa kwekubhadhara kusina hanya kweUWB, kune rumwe rutivi, kunoenderana nekuti nharembozha dzine basa reUWB rakavakirwa mukati chete dzinogona kufarirwa mumusika here. Parizvino, mamwe mamodheru eApple, Samsung, Xiaomi neVIVO chete ndiwo anotsigira UWB, uye OPPO inotangawo chirongwa che "one-button connection" cheUWB mobile case, saka kufarirwa kwemodheru neveruzhinji kuchiri kushoma. Zvinoramba zvichionekwa kana ichikwanisa kusvika pakuzivikanwa kweNFC munharembozha, uye kusvika pahukuru hwebluetooth kuchiri chiono. Asi tichitarisa kubva pa "roll-in" yevagadziri vefoni varipo, zuva reUWB semazuva ese harizove kure zvakanyanya.
Kune rumwe rutivi, kune hunyanzvi husingaperi hwezviitiko zvevatengi zvinogara zvichiitika. UWB yekutevera vatengi, nzvimbo, kudzora kure, kubhadhara kuri kuwedzerwa nevagadziri vepakati: Apple's Airtag, Xiaomi's One Finger, makiyi emotokari edhijitari eNiO, Huawei's fusion signal indoor positioning, NXP's ultra-wideband radar, Huidong's metro payment… Zvirongwa zvakasiyana-siyana zvekuwedzera kuwanda kwevatengi zvinoramba zvichichinja, kuitira kuti vatengi vanzwe kubatanidzwa kwetekinoroji nehupenyu, zvichiita kuti UWB ive izwi rakakwana rekuputsa denderedzwa.
