Kodi mauna ndi chiyani?
Mesh Network ndi kapangidwe ka topology ka maukonde. Pakati pa netiweki ya Mesh, deta imatha kutumizidwa kuchokera ku node iliyonse kupita ku netiweki yonse, ndipo imodzi mwa node pamaneti ikalephera, netiweki yonse imathabe kulumikizana bwino, ili ndi maubwino ochezera pa intaneti komanso kuthekera kolimbana ndi kusokoneza. .
Kodi BLE Bluetooth ndi chiyani Mesh?
Bluetooth v5.0 idawonjezera gawo la BLE. Poyerekeza ndi bluetooth yachikhalidwe, ble mesh network ili ndi chivundikiro chachitali komanso kulumikizana kopanda malire, imathetsanso zovuta zolumikizirana ndi Bluetooth, tsopano imakhala magawo akulu a IOT.
BLE Mesh imakhala ndi Mobile ndi Node. Mobile amatanthauza foni yamakono. Smartphone ngati mbali yowongolera ma mesh network. Node ndi chipangizo cha node mu netiweki. BLE Mesh network ntchito imatheka kudzera njira yowulutsa. Njira zoyambira ndi izi:
- Kuwulutsa deta kuchokera mu node A;
- Node B imawulutsa zomwe zili mu node A mutalandira deta kuchokera ku node A.
- Ndi zina zotero, mwa njira ya matenda, mmodzi amadutsa khumi, khumi akufalikira, kotero kuti zipangizo zonse zopanda zingwe zalandira deta iyi.
Kugwiritsa ntchito njirayi molumikizana ndi ma algorithms athu anzeru kumatha kutumiza mauthenga bwino pamanetiweki ndikuchepetsa zovuta zomwe zimachitika chifukwa cha mphepo yamkuntho ndi sipamu. Ndipo BLE Mesh imasunganso zomwe zili mu netiweki kuti zipewe kuba deta yapaintaneti kudzera pakuwunika komanso kuwukira kwapakati.
Pangani makina owunikira anzeru ndi BLE Mesh. Dongosololi lili ndi mitundu iwiri ya zida zomwe zimaphatikizira kusinthana ndi magetsi anzeru, foni yam'manja monga kutha kwa maukonde. Choyamba, magetsi anzeru ndi masiwichi amagawidwa m'zipinda ziwiri, kenako amazigawa muukonde kudzera pa foni yanzeru, ndikuzigawa m'magulu malinga ndi manambala achipinda. Netiweki ya BLE Mesh yotere yatha, palibe chifukwa chowonjezera chida chilichonse cholumikizira. Magetsi awiri anzeruwa amatha kuwongoleredwa mwachindunji ndi chosinthira. Kuwongolera uku sikufuna kutenga nawo gawo kwa foni yamakono. Kupanga magulu ndikwaulere, mutha kusakaniza momasuka magetsi anzeru ndi masiwichi malinga ndi zomwe mumakonda. Smartphone imathanso kukweza magetsi anzeru mosavuta. Pamene chiwerengero cha magetsi anzeru pamanetiwo chikuwonjezeka, malo omwe ali ndi netiweki akuchulukiranso.
Ichi ndi chiyambi chabe, cholumikizidwa ndi netiweki ya BLE Mesh, imatha kuwonjezera masensa otsika kwambiri komanso zida zanzeru pamanetiweki. Kenako agawane ndi foni yamakono ndikuwathandiza kuti azigwira ntchito limodzi. Chirichonse chimakhala chanzeru.
Netiweki ya ZigBee Mesh imakhala ndi Coordinator(C), Router(R) ndi End Device(D) . Ma network onse amayendetsedwa ndi C, C amatha kulumikizana mwachindunji ndi D, koma ngati D ndi C zili patali kwambiri, ziyenera kulumikizidwa ndi R pakati. Sichingathe kuyankhulana pakati pa D ndi D, koma ikhoza kuonjezera R kuti ikulitse maukonde.
ubwino BLE Bluetooth thumba
BLE Mesh network ndiyosavuta, maukonde amapangidwa ndi zida zokha, ndipo safuna kutenga nawo gawo pa rauta. Mbali yowongolera imagwiritsa ntchito foni yanzeru, Pamene ikupereka mwayi kwa ogwiritsa ntchito, imapulumutsanso mtengo womanga netiweki. Chifukwa kukulitsa kwa netiweki sikufuna kuti rauta alowe nawo, maukonde ndi osavuta kuyika.
Kuphatikiza apo pali mwayi waukulu, masiku ano, mafoni anzeru, mapiritsi ndi makompyuta ali ndi Bluetooth, ogwiritsa ntchito amalumikizana ndi netiweki ya BLE Mesh kudzera pa Bluetooth, kupewa kuchedwa ndi ziwalo zomwe zimayambitsidwa ndi netiweki, komanso safunikira kukonza chipata cha Complex. Kupititsa patsogolo kwambiri kwa ogwiritsa ntchito.
Mwachidule mu mfundo zotsatirazi:
- Kapangidwe ka maukonde ndi kosavuta, kosavuta kuyika.
- sichifuna zida zoyendera ndi wogwirizanitsa, mtengo wake ndi wotsika.
- Kufikira kudzera pa Bluetooth, pewani kuchedwa kwa netiweki.
- Imathetsa vuto lakusintha chipata cha ogwiritsa ntchito omwe safuna maukonde osiyanasiyana
- Mafoni am'manja ali ndi Bluetooth, osavuta kulimbikitsa.
