Kuyika m'nyumba kumatha kuonedwa ngati malo opanda kanthu ogwiritsira ntchito, ndipo palibe ukadaulo woyenera kwambiri kuti ukwaniritse ntchitoyi. Zizindikiro za GPS za m'nyumba ndizosauka, ndipo malo a RSSI amachepa chifukwa cha kulondola komanso kusiyanasiyana, ndipo ndizovuta kupereka ntchito zokhutiritsa. Kutulutsidwa kwaposachedwa kwa bulutufi 5.1 yabweretsa njira yatsopano yopezera mayendedwe, yomwe ingapereke kulondola kwa malo a centimita, ndipo imapereka yankho lodalirika laukadaulo pakuyika m'nyumba.
Momwe mungakwaniritsire malo a "centimeter-level" a Bluetooth 5.1?
Pambuyo pa kukhazikitsidwa kwa Direction Finding mu Bluetooth 5.1 core specification, kulondola kwa malo a Bluetooth kumatha kukonzedwa kukhala "centimeter-level". Izi zili choncho chifukwa ntchito yopeza mayendedwe a Bluetooth 5.1 imapangidwa makamaka ndi zinthu ziwiri zoyikira, zomwe ndi AoA (Angle of Arrival) ndi AoD (Angle of Departure).
AoA ndi njira yopezera azimuth ndi mtunda wa transmitter ndi wolandila ndi triangulation poyesa njira yakufika kwa ma sign omwe akuyandikira wolandila, makamaka kwa RTLS (dongosolo lenileni la nthawi), kutsatira zinthu ndi chidziwitso chodziwika bwino. Chipangizo chowongolera chimagwiritsa ntchito mlongoti umodzi kuti utumize seti yeniyeni ya mapaketi opeza mayendedwe, ndipo chipangizo cholandirira chimakhala ndi tinyanga zambiri. Ma antennas osiyanasiyana a chipangizo cholandirira adzakhala ndi nthawi yocheperako polandila paketi yopeza mayendedwe a chipangizo choyikira. Kusintha kwa gawoli komwe kumachitika chifukwa cha siginecha yam'mbali pa mlongoti wolandila kumatchedwa zitsanzo za IQ za siginecha. Kenako santhulani mtengo wa IQ kuti mupeze chidziwitso cholondola cha chipangizocho.
Kodi Bluetooth 5.1 Imakwaniritsa Bwanji Centimeter-Level Positioning
AoD imagwiritsanso ntchito ukadaulo wamagawo azizindikiro, ma triangulation ake amachitidwa poyesa komwe amanyamulira ma siginecha kuchokera pa transmitter, makamaka pamakina oyika m'nyumba. Tekinoloje yopeza mayendedwe iyi ndiyoyenera kuyang'anira zinthu zamkati, kukonza, ndi kusunga. Woyimilirayo amatumiza mapaketi opeza mayendedwe kudzera m'magulu angapo a antenna, ndipo choyikapo chimalandira paketi yopeza mayendedwe ndikuwerengera zomwe zidayikidwa pazitsanzo ndi kusanthula kwamitengo ya IQ.
Kodi Bluetooth 5.1 Imakwaniritsa Bwanji Centimeter-Level Positioning
Kuphatikiza njira za AoA ndi AoD, kulondola kwa malo kwa Bluetooth 5.1 kwafika pamlingo wa centimita, ndipo kumatha kukwaniritsa malo amkati a 3D.
Kodi nkhaniyi ikukuthandizani kuti mutuluke mum'mene Bluetooth 5.1 imagwiritsidwira ntchito poyikira mulingo wa centimita? Ngati sichoncho, musazengereze kulumikizana ndi Feasycom kuti mudziwe zambiri.
Feasycom ndi imodzi mwamabizinesi oyambirira komanso akuluakulu Opanda zingwe ku China. Zogulitsa zathu ndizo Gawo la Bluetooth, Wi-Fi Module, Bluetooth Beacon, Gateway, ndi Mayankho Opanda zingwe. Chonde pitani patsamba lathu www.feasycom.com kuti mudziwe zambiri kapena pempho SAMPILI ZAULERE.
