Zikafika pamalipiro osagwiritsa ntchito inductive, ndizosavuta kuganiza za kulipira kwa ETC, komwe kumazindikira kulipira kokha kwa brake yamagalimoto kudzera paukadaulo wolumikizana ndi ma radio frequency a semi-active RFID. Ndi kugwiritsa ntchito bwino kwaukadaulo wa UWB, anthu amathanso kuzindikira kulowetsedwa pachipata ndikuchotsa zokha akamayenda munjanji yapansi panthaka.
Posachedwapa, pulatifomu ya mabasi ya Shenzhen "Shenzhen Tong" ndi Huiting Technology pamodzi adatulutsa njira yolipirira ya UWB ya "non-inductive off-line brake" pachipata cha subway. Kutengera ma multi-chip complex RADIO frequency system, yankho limatenga njira yonse yachitetezo cha "eSE + COS + NFC + BLE" ya Huiting Technology, ndipo imanyamula chipangizo cha UWB cha malo ndikusintha kotetezeka. Kudzera pa foni yam'manja kapena khadi ya basi yophatikizidwa ndi chip ya UWB, wogwiritsa ntchito amatha kudzizindikiritsa yekha akadutsa mabuleki, ndikumaliza kutsegula ndi kutsitsa mtengo wakutali.
Malinga ndi kampaniyo, yankho limaphatikiza ma protocol a NFC, UWB ndi ma driver ena mu chipangizo chotsika cha Bluetooth SoC, amachepetsa zovuta zokweza chipata kudzera pakusintha kwamitundu yophatikizika, ndipo imagwirizana ndi chipata cha NFC. Malinga ndi chithunzi chovomerezeka, malo oyambira a UWB akuyenera kukhala pachipata, ndipo chindapusa cha chindapusacho chili mkati mwa 1.3m.
Si zachilendo kuti UWB (ukadaulo wa Ultra-wideband) ugwiritsidwe ntchito pakulipira kopanda ndalama. Ku Beijing International Urban njanji Transit Exhibition mu Okutobala 2021, Shenzhen Tong ndi VIVO adawonetsanso njira yogwiritsira ntchito "malipiro osagwirizana ndi digito RMB ya brake yasitima yapansi panthaka" potengera ukadaulo wa UWB, ndipo adazindikira kuti kulipiritsa kosagwirizana ndi UWB + NFC chip. ndi VIVO prototype. M'mbuyomu mu 2020, NXP, DOCOMO ndi SONY adatulutsanso chiwonetsero chazogulitsa zatsopano za UWB mu Mall, kuphatikiza kulipira mopanda chidwi, kulipira kwa magalimoto opezeka, komanso kutsatsa kolondola ndi ntchito zamalonda.
Ma Positioning Enieni + Malipiro Osamva, UWB Ilowa Pamalipiro Pafoni
NFC, bluetooth, ir ndi ambiri m'munda wa pafupi malipiro munda ntchito, NFC (pafupi ndi munda luso kulankhulana) chifukwa cha makhalidwe a chitetezo mkulu, sayenera chikugwirizana ndi magetsi, panopa mu zitsanzo wamba ambiri ntchito mu foni yam'manja, m'malo monga Japan ndi South Korea, mafoni a m'manja a NFC angagwiritsidwe ntchito ngati kutsimikizira kokwerera ndege, mayendedwe, khomo lolowera kiyi IC khadi, kirediti kadi, kirediti kadi, ndi zina zambiri.
UWB ultra-wideband technology, yokhala ndi ultra-wideband pulse signal (UWB-IR) nanosecond yankho la nanosecond, kuphatikizapo TOF, TDoA/AoA kuyambira aligorivimu, kuphatikizapo mzere wa mawonedwe (LoS) ndi osawona mzere (nLoS) ) zithunzi zimatha kukwaniritsa kulondola kwamayendedwe a centimita. M'nkhani zam'mbuyomu, Iot Media idayambitsa pulogalamuyi mwatsatanetsatane m'malo am'nyumba, makiyi amagalimoto a digito ndi magawo ena mwatsatanetsatane. UWB ili ndi mawonekedwe olondola kwambiri, kuchuluka kwa kufalikira, kukana kusokoneza ma sign ndi kutsekereza, zomwe zimapatsa ubwino wachilengedwe pogwiritsira ntchito malipiro osagwiritsa ntchito ndalama.
Mfundo yolipira chipata chapansi panthaka ndiyosavuta. Mafoni am'manja ndi makhadi amabasi okhala ndi ntchito ya UWB amatha kuwonedwa ngati tag ya UWB. Malo oyambira akazindikira momwe tagi ilili, imatseka ndikuyitsatira. UWB ndi eSE chitetezo chip + NFC kuphatikiza kuti mukwaniritse zolipirira zotetezedwa zandalama.
Ntchito ya NFC + UWB, ntchito ina yotchuka ndi kiyi yagalimoto. Pankhani ya makiyi a digito yamagalimoto, mitundu ina yapakati komanso yapamwamba ya BMW, NIO, Volkswagen ndi mitundu ina yatengera dongosolo la "BLE + UWB + NFC". Kuzindikira kwakutali kwa Bluetooth kumadzutsa UWB pakutumiza kwa data, UWB imagwiritsidwa ntchito pakuzindikira kolondola, ndipo NFC imagwiritsidwa ntchito ngati njira yosunga zobwezeretsera kulephera kwamagetsi kuti ikwaniritse zowongolerera pamayendedwe osiyanasiyana komanso magetsi.
UWB Kuchulukitsa Malo, Kupambana kapena Kulephera Kumadalira Mbali ya Ogula
Kuphatikiza pa kuyika kolondola, UWB imakhalanso yodabwitsa kwambiri pakutumiza kwa data mtunda waufupi kwambiri. Komabe, m'munda wa mafakitale Internet Zinthu, chifukwa cha kuyambika mofulumira ndi kutchuka msika wa Wi-Fi, Zigbee, BLE ndi mfundo zina protocol, UWB akadali angathe mkulu-mwatsatanetsatane m'nyumba udindo, kotero kufunika mu B- msika wotsiriza uli m'mamiliyoni okha, omwe ali amwazikana. Msika woterewu ndi wovuta kwa opanga chip kuti akwaniritse ndalama zokhazikika.
Motsogozedwa ndi kufunikira kwamakampani, C-end ogula intaneti ya Zinthu yakhala gawo lalikulu lankhondo m'malingaliro a opanga UWB. Zamagetsi ogula, ma tag anzeru, nyumba zanzeru, magalimoto anzeru, komanso kulipira kotetezeka kwakhala njira zazikulu zofufuzira ndi chitukuko cha NXP, Qorvo, ST ndi mabizinesi ena. Mwachitsanzo, m'malo oletsa mwayi wofikira, kulipira mopanda chidwi komanso nyumba yanzeru, UWB imatha kusintha Zokonda kunyumba malinga ndi chidziwitso cha ID. Pamagetsi ogula, mafoni a UWB ndi zida zawo zitha kugwiritsidwa ntchito ngati m'nyumba, kuyang'anira ziweto, komanso kutumiza ma data mwachangu.
Chen Zhenqi, CEO wa Newwick, kampani yapanyumba ya UWB chip, adanenapo kuti "mafoni anzeru ndi magalimoto, monga ma terminals ofunikira kwambiri komanso anzeru kwambiri m'tsogolomu pa intaneti pa chilichonse, adzakhalanso msika waukulu kwambiri waukadaulo wa UWB". Kafukufuku wa ABI waneneratu kuti mafoni okwana 520 miliyoni a UWB adzatumizidwa pofika chaka cha 2025, ndipo 32.5% mwa iwo adzaphatikizidwa ndi UWB. Izi zimapatsa opanga UWB zambiri zoti aganizire, ndipo Qorvo amayembekeza kutumiza kwa UWB kuti kufanane ndi kugwiritsidwa ntchito kwa Bluetooth m'tsogolomu.
Ngakhale ziyembekezo za kutumiza chip ndizabwino, Qorvo adati vuto lalikulu pamakampani a UWB ndi kusowa kwa unyolo wathunthu wamafakitale kuti uthandizire. Mabizinesi a UWB akumtunda akuphatikiza NXP, Qorvo, ST, Apple, Newcore, Chixin Semiconductor, Hanwei Microelectronics ndi mabizinesi ena, pomwe mtsinje wapakatikati uli ndi opanga ma module ophatikizira, opanga masiteshoni, mafoni am'manja ndi opanga zida zotumphukira.
Mwamsanga kampani chinkhoswe mu chitukuko cha UWB Chip, lalikulu zedi "MaoJian", koma akhoza alibe muyezo wa Chip, makampani n'kovuta kupanga mfundo kulumikiza ogwirizana monga bluetooth, pakati ndi m'munsi kufikira mafakitale unyolo mavenda ayenera. kuti mugwiritse ntchito zambiri zogwiritsira ntchito, yambitsani wosuta pa ntchito ya UWB pafupipafupi yogwiritsira ntchito, kuchokera pazotsatira, Kupambana kapena kulephera kwa msika wa UWB kumawoneka kuti kukukhala kumbali ya ogula.
Pomaliza pake
Kukwezeleza kwa malipiro osakhudzidwa ndi UWB, kumbali imodzi, kumadalira ngati mafoni a m'manja omwe ali ndi ntchito ya UWB akhoza kutchuka pamsika. Pakadali pano, mitundu ina yokha ya Apple, Samsung, Xiaomi ndi VIVO imathandizira UWB, ndipo OPPO imakhazikitsanso dongosolo la "batani limodzi" la foni yam'manja ya UWB, kotero kutchuka kwachitsanzo ndi anthu akadali ochepa. Zikuwonekerabe ngati zingagwirizane ndi kutchuka kwa NFC pama foni am'manja, komanso kufikira kukula kwa bluetooth akadali masomphenya. Koma kutengera "kulowetsa" kwa opanga mafoni aposachedwa, tsiku la UWB monga muyezo silidzakhala kutali kwambiri.
Kumbali inayi, pali kusinthika kosatha kwa zochitika zapamwamba za ogula. UWB yotsata ogula, malo, chiwongolero chakutali, malipiro akukulitsidwa ndi opanga apakatikati: Airtag ya Apple, Chala Chimodzi cha Xiaomi, makiyi agalimoto a digito a NiO, Huawei's fusion sign indoor positioning, radar ya NXP's Ultra-wideband, Malipiro a metro a Huidong… Zosiyanasiyana zokha njira zatsopano zowonjezerera kuchuluka kwa ogula zimasintha, kotero kuti ogula azitha kumva kusakanikirana kopanda malire kwaukadaulo ndi moyo, kupanga UWB kukhala mawu okwanira kuswa bwalo.
