Ukadaulo wa Bluetooth umatsimikizira mphamvu yolumikizira. Zida zopitilira 3.6 biliyoni zimatumiza chaka chilichonse pogwiritsa ntchito Bluetooth kulumikiza. Kwa mafoni, mapiritsi, ku ma PC, kapena kwa wina ndi mzake.
Ndipo Bluetooth imathandizira njira zambiri zolumikizirana. Atatha kuwonetsa mphamvu zolumikizira zosavuta, Bluetooth tsopano ikuthandizira kusintha kwa ma beacon padziko lonse lapansi kudzera pamalumikizidwe owulutsa, ndikufulumizitsa misika yatsopano, monga nyumba zanzeru, kudzera mu kulumikizana kwa mauna.
Mabaibulo a Wailesi
Wailesi yoyenera, ntchito yoyenera.
Kugwira ntchito mu 2.4GHz yopanda chilolezo cha mafakitale, sayansi ndi zamankhwala (ISM) pafupipafupi bandi, ukadaulo wa Bluetooth umathandizira njira zingapo zamawayilesi zomwe zimathandiza opanga kupanga zinthu zomwe zikugwirizana ndi zomwe zimafunikira kulumikizidwa kwa msika wawo.
Kaya ndi chinthu chomwe chimawulutsa mawu apamwamba kwambiri pakati pa foni yam'manja ndi sipika, kutumiza data pakati pa piritsi ndi chipangizo chachipatala, kapena kutumiza mauthenga pakati pa masauzande ambiri munjira yopangira makina, mawayilesi a Bluetooth Low Energy ndi Basic Rate/Enhanced Data Rate adapangidwa. kukwaniritsa zosowa zapadera za opanga padziko lonse lapansi.
Bluetooth Low Energy (LE)
Wailesi ya Bluetooth Low Energy (LE) idapangidwa kuti igwire ntchito yamagetsi ochepa kwambiri, ndipo imakongoletsedwa ndi njira zosinthira deta. Kuti azitha kugwira ntchito modalirika mu band ya frequency ya 2.4 GHz, imagwiritsa ntchito njira yolimba ya Adaptive Frequency Hopping yomwe imatumiza deta pamayendedwe 40. Wailesi ya Bluetooth LE imapatsa opanga kusinthasintha kwakukulu, kuphatikiza zosankha zingapo za PHY zomwe zimathandizira mitengo ya data kuchokera ku 125 Kb/s mpaka 2 Mb/s, komanso mphamvu zingapo, kuchokera pa 1mW mpaka 100 mW. Imathandiziranso zosankha zachitetezo mpaka pagulu la boma, komanso ma topology angapo pamanetiweki, kuphatikiza point-to-point, broadcast, and mesh.
Bluetooth Basic Rate/Data Yowonjezereka (BR/EDR)
Wailesi ya Bluetooth BR/EDR idapangidwa kuti igwire ntchito yotsika mphamvu ndipo imakometsedwa kuti igwiritse ntchito zotsatsira deta monga ma audio opanda zingwe. Imathandiziranso njira yolimba ya Adaptive Frequency Hopping, kutumiza deta pamayendedwe 79. Wailesi ya Bluetooth BR/EDR imaphatikizapo zosankha zingapo za PHY zomwe zimathandizira mitengo ya data kuchokera ku 1 Mb/s mpaka 3 Mb/s, ndipo imathandizira milingo yamagetsi angapo, kuyambira 1mW mpaka 100 mW. Imathandizira zosankha zingapo zachitetezo komanso malo ochezera pa intaneti.
Zosankha za Topology
Zipangizo zimafuna njira zingapo zolumikizirana.
Kuti zikwaniritse zosowa zamalumikizidwe opanda zingwe za anthu osiyanasiyana opanga mapulogalamu, ukadaulo wa Bluetooth umathandizira zosankha zingapo za topology.
Kuchokera pamalumikizidwe osavuta ofikira pamawu omvera pakati pa foni yam'manja ndi wokamba nkhani, kuwulutsa maulumikizidwe othandizira njira yopezera ntchito pa eyapoti, kulumikizana ndi mauna othandizira ma automation akunyumba, Bluetooth imathandizira zosankha zakutsogolo zomwe zimafunikira kuti zikwaniritse zapadera. zosowa za opanga padziko lonse lapansi.
MFUNDO-KUPITA-MFUNDO
Point-to-Point (P2P) yokhala ndi Bluetooth BR/EDR
P2P topology yomwe ikupezeka pa Bluetooth® Basic Rate/Enhanced Data Rate (BR/EDR) imagwiritsidwa ntchito pokhazikitsa kulumikizana kwa chipangizo cha 1: 1, ndipo imakongoletsedwa kuti imveke bwino, ndikupangitsa kuti ikhale yabwino kwa olankhula opanda zingwe, zomvera m'makutu ndi opanda manja mgalimoto m'galimoto. machitidwe.
Ma waya opanda zingwe a Bluetooth
Zomverera m'makutu za Bluetooth ndizofunikira kukhala nazo pama foni am'manja. Mayankho atsopano ochita bwino kwambiri amakulolani kuti muyimbe ndikulandila mafoni muofesi kapena popita pomwe mumaperekanso zosankha za nyimbo zapamwamba kwambiri.
mafoni Bluetooth okamba
Kaya ndi zosangalatsa zapamwamba m'nyumba kapena njira yonyamulika ya kugombe kapena paki, pali woyankhulira wa mawonekedwe ndi kukula kulikonse kuti akwaniritse zosowa zanu zenizeni. Ngakhale zili choncho mu dziwe.
M'galimoto machitidwe
Chofunikira kwambiri pamsika wamagalimoto, ukadaulo wa Bluetooth uli m'magalimoto opitilira 90% omwe amagulitsidwa lero. Kufikika kwa zingwe za Bluetooth kumatha kupititsa patsogolo chitetezo cha oyendetsa ndikuwonjezera chisangalalo chamgalimoto.
Point-to-Point (P2P) yokhala ndi Bluetooth LE
P2P topology yomwe ikupezeka pa Bluetooth Low Energy (LE) imagwiritsidwa ntchito pokhazikitsa kulumikizana kwa chipangizo cha 1: 1, imakonzedwa kuti isamutsidwe, ndipo ndiyabwino pazinthu zolumikizidwa pazida monga zotsata zolimbitsa thupi ndi zowunikira zaumoyo.
Masewera & kulimbitsa thupi
Bluetooth LE imapereka kusamutsa kwa data ndi kugwiritsa ntchito mphamvu zochepa, zomwe zimapangitsa kuti zikhale zotheka kukonzekeretsa mitundu yonse yamasewera ndi zida zolimbitsa thupi zolumikizidwa ndi zingwe. Masiku ano, mayankho a Bluetooth amayambira pakutsata zolimbitsa thupi mpaka pazida zamakono zomwe zimathandiza kukonza bwino kachitidwe ka akatswiri othamanga.
Thanzi ndi thanzi
Kuchokera pamisuwachi ndi zowunikira kuthamanga kwa magazi kupita ku makina onyamula a ultrasound ndi x-ray, ukadaulo wa Bluetooth umathandizira anthu kuyang'anira ndikuwongolera moyo wawo wonse ndikupangitsa kuti azithandizo azachipatala azipereka chisamaliro chosavuta.
PC zotumphukira & Chalk
Mphamvu yoyendetsera Bluetooth imakumasulani ku mawaya. Kuchokera pa laputopu kupita ku mafoni a m'manja, zida zomwe mumalumikizana nazo tsiku lililonse zimayenda mwachangu. Kaya ndi kiyibodi, trackpad, kapena mbewa, chifukwa cha Bluetooth, simufunikanso mawaya kuti mukhale olumikizidwa.
CHONSE
Bluetooth Low Energy (LE) imathandizira kulumikizana kopanda zingwe kwakanthawi kochepa ndipo imagwiritsa ntchito ma topology angapo pamanetiweki, kuphatikiza topology yowulutsa pazida zambiri (1: m) kulumikizana ndi chipangizo. The Bluetooth LE broadcast topology imathandizira kugawana zidziwitso zakomweko ndipo ndiyoyenera kuyankha kwa ma beacon, chidziwitso chachiwongola dzanja (PoI) ndi zinthu ndi ntchito zopezera njira.
Ma beakoni okonda chidwi
Kusintha kwa nyali kuli pa ife. Ogulitsa adatengera ma beacon a malo okonda chidwi (PoI) koyambirira, koma mizinda yanzeru tsopano ikupeza njira zambiri zosinthira moyo wa nzika ndi alendo. Ntchito mkati mwa malo osungiramo zinthu zakale, zokopa alendo, maphunziro ndi zoyendera ndizosatha.
Kupeza zinthu
Kodi munatayapo makiyi, chikwama kapena chikwama chanu? Ma beacons a Bluetooth amathandizira kutsata kwazinthu zomwe zikukula mwachangu ndikupeza msika. Njira zotsika mtengo zotsata zinthu zimakuthandizani kupeza pafupifupi chilichonse chomwe muli nacho. Ambiri mwa mayankhowa amaperekanso maukonde otsogola ozikidwa pamtambo ndi ntchito.
Ma beacons opeza njira
Kodi mukuvutika kupeza njira yodutsa ma eyapoti omwe ali ndi anthu ambiri, masukulu kapena masitediyamu? Maukonde a ma beacon okhala ndi ntchito zopezera njira atha kukuthandizani kuti mufikire pachipata chomwe mukufuna, nsanja, kalasi, mpando kapena malo odyera. Zonse kudzera pa pulogalamu pa foni yanu yam'manja.
MESH
Bluetooth® Low Energy (LE) imathandizira ma mesh topology kuti akhazikitse kulumikizana kwa zida zambiri mpaka zambiri (m:m). Kuthekera kwa ma mesh kumakonzedwa kuti apange maukonde akulu akulu kwambiri ndipo ndi koyenera kupanga makina opangira okha, ma sensor network ndi njira zotsatirira katundu. Ma network a Bluetooth mesh okha ndi omwe amabweretsa kugwirizana kwapadziko lonse lapansi komanso kukhwima, kodalirika, komwe kumalumikizidwa ndiukadaulo wa Bluetooth pakupanga zida zamafakitale.
Kupanga zochita zokha
Njira zatsopano zowongolera ndi zodzipangira zokha, kuyambira pakuwunikira mpaka kutenthetsa / kuziziritsa mpaka chitetezo, zikupanga nyumba ndi maofesi kukhala anzeru kwambiri. Maukonde a Bluetooth mesh amathandizira nyumba zanzeruzi, zomwe zimathandiza makumi, mazana kapena masauzande a zida zopanda zingwe kuti azilumikizana modalirika komanso motetezeka.
Ma network opanda zingwe
Msika wa wireless sensor network (WSN) ukukula mwachangu. Makamaka m'mafakitale a WSNs (IWSN) komwe makampani ambiri akupanga ndalama zambiri komanso kukonza bwino ma WSN omwe alipo. Maukonde a Bluetooth mesh adapangidwa kuti akwaniritse kudalirika, scalability ndi zofunikira zachitetezo cha ma IWSN.
Kutsata chuma
Wokhoza kuthandizira topology yowulutsa, Bluetooth LE idakhala njira yowoneka bwino yotsatirira katundu pa RFID yogwira. Kuphatikizika kwa ma mesh network kudakweza malire amtundu wa Bluetooth LE ndikukhazikitsa njira zotsatirira chuma za Bluetooth kuti zigwiritsidwe ntchito m'malo omanga akuluakulu komanso ovuta.
