Sida aan ognahay, marka la eego macnaha guud ee internetka ee Waxyaabaha, helitaanka iyo ku dhaqanka macluumaadka goobta ayaa noqda mid aad iyo aad muhiim u ah. Marka la barbardhigo meelaynta dibadda, jawiga shaqada ee meelaynta gudaha waa mid aad u adag oo jilicsan, tignoolajiyadasuna aad ayey u kala duwan tahay. Tusaale ahaan, shaqaalaha warshadda smart iyo maamulka xamuulka iyo jadwalka, maaraynta badbaadada wax soo saarka, baarkinka dhulka hoostiisa ee baabuurka navigation, shaqaalaha dhismaha smart / maamulka meelaynta booqdaha, bandhig goobta navigation, iwm.
Guud ahaan, waxaan u qaybin karnaa tignoolajiyada meelaynta gudaha Wi-Fi meelaynta, meelaynta ZigBee, meelaynta Bluetooth, meelaynta UWB, meelaynta RFID, meelaynta dayax-gacmeedka, meelaynta kiciyeyaasha-hooseeya, meelaynta saldhiga saldhiga, meelaynta dhawaaqa, meelaynta indhaha, meelaynta geomagnetic, iwm. Aynu ka wada hadalno saddexda tignoolajiyada meelaynta gudaha gudaha ee WiFi, UWB iyo Bluetooth.
module Wi-Fi
Meelaynta Wi-Fi ayaa la bilaabay in lagu dabaqo dhinaca kormeerka shaqaalaha iyadoo lagu saleynayo meelaynta summada agagaarka 2010. Sannadkii 2013, codsiyada sida ogaanshaha Wi-Fi ee ku salaysan taleefannada gacanta ayaa sidoo kale soo baxay.
Waqtigan xaadirka ah, meelaynta Wi-Fi waa tignoolajiyada meelaynta gudaha ee caanka ah, qaabkeeda meelayntuna waxay ku salaysan tahay habka fidinta xoogga calaamada iyo habka aqoonsiga faraha.
Habka faafinta xoogga calaamada waxaa loola jeedaa isticmaalka nooc gaar ah oo kanaalka sii dhacaya oo loo maleynayo jawiga hadda jira si loo qiyaaso masaafada u dhexeysa terminaalka iyo goobta la yaqaan AP iyadoo loo eegayo xiriirkeeda xisaabeed. Haddii isticmaaluhu uu maqlo calaamado badan oo AP ah, waxa uu dhex mari karaa saddexda dhinac ee Positioning algorithm si uu u helo macluumaadka goobta isticmaaluhu; Habka aqoonsiga faraha wuxuu ku salaysan yahay sifooyinka faafinta ee calaamadda Wi-Fi, xogta ogaanshaha ee APs badan ayaa lagu daraa macluumaadka faraha, iyo booska suurtogalka ah ee shayga dhaqaaqa waxaa lagu qiyaasaa marka la barbardhigo xogta tixraaca.
Xaaladaha qaarkood halka saxnaanta meelaynta ay tahay heerka mitirka, Wi-Fi waxa loo isticmaali karaa caymis. Farsamadani waxay ku habboon tahay meelaynta iyo socodka dadka/baabuurta, xarumaha caafimaadka, xarumaha wax iibsiga, jardiinooyinka mawduucyada, iyo xaaladaha kale.
Qaybta Bluetooth
Qiyaastii 2014, tignoolajiyada meelaynta ku salaysan Bluetooth ayaa bilowday in lagu dabaqo dhinaca la socodka iyo meelaynta.
Bishii Luulyo 2017, mesh Bluetooth ayaa si rasmi ah loo bilaabay. Sannad iyo badh gudahood, in ka badan 105 badeecooyin leh hawlaha shabakadda mesh Bluetooth ayaa la shahaadeeyay, oo ay ku jiraan chips, xidhmooyin borotokoolka, qaybo, iyo alaab-qeybiyeyaal alaabeed.
Si loo daboolo baahida sii kordheysa ee suuqa adeegga goobta, heerka cusub ee Bluetooth 5.1 wuxuu ku daray hawl jiho ah, kaas oo ka caawin kara aaladda inuu caddeeyo jihada calaamadda Bluetooth-ka, ka dibna ka caawinta horumariyaha inuu fasiro xalka u dhowaanshaha Bluetooth jihada aaladda si loo gaadho meel-beeg sentimitir ah Nidaamka meelaynta saxda ah ee Bluetooth.
Xalalka adeegga Bluetooth-ku-salaysan ee goobta ku salaysan ayaa guud ahaan loo qaybiyaa laba qaybood: xalalka u dhow iyo nidaamyada meelaynta. Hadday tahay meelaynta waqtiga-dhabta ah ama meelaynta gudaha, mabda'a ayaa la mid ah. Taasi waa, habka RSSI (helay xoogga signalada) waxaa lagu daraa gudbinta baakidhka xogta, iyo qiyaasta qiyaasta alaabta waxaa lagu sawiraa RSSI. Algorithm cabbirka, iyo ugu dambeyntii dhammaystir meelaynta gudaha.
Meelaynta Bluetooth-ka, ilaa iyo inta shaqada Bluetooth-ka aaladda ay shidantahay, waad heli kartaa. Iyadoo la sii daayay Bluetooth 5.x iyo talefanno badan oo casriga ah/pads/laptop-yada ku xidhan Bluetooth, Bluetooth waxa la filayaa in ay qayb badan ka qaadato suuqa adeega ku salaysan. Marka loo eego "Cusbooneysiinta Suuqa Bluetooth 2019", adeegyada goobtu waxay noqdeen xalka ugu kobaca badan ee Bluetooth, heerka kobaca sanadlaha ee isku dhafka ah ayaa la filayaa inuu gaaro 43% shanta sano ee soo socota.
Meelaynta Bluetooth-ka waxa loo isticmaalaa meelaynta dadka/hanti yar iyo baaxadba labadaba, sida hoolal hal dabaq ah ama dukaamada, hoolalka bandhiga, garoommada, bakhaarada, warshadaha.

Sanadihii la soo dhaafay, sida xalalka UWB chip ay qaangaareen kharashkuna hoos u dhacay, shirkadaha gudaha ee baranaya tignoolajiyada meelaynta UWB ayaa soo baxay. UWB waa tignoolajiyada meelaynta wirelesska oo leh xadiga gudbinta sare (ilaa 1000Mbps ama ka badan), awood gudbineed hooseeya iyo awood galmo oo xoogan.
Meelaynta UWB waa dareeme badan oo isticmaalaya TDOA (Farqiga Wakhtiga Imaansho, wakhtiga kala duwanaanshaha imaatinka) iyo AOA meelaynta algorithm si loo falanqeeyo booska summada, oo leh xalinta dariiqyada badan, saxnaanta sare, saxnaanta meelaynta waxay gaari kartaa heerka sentimitir iyo sifooyin kale.
TDOA waa hab meelaynta iyadoo la isticmaalayo kala duwanaanshaha wakhtiga imaatinka, sidoo kale loo yaqaan meelaynta hyperbolic. Kaarka sumadu wuxuu u soo diraa calaamada UWB dibadda, iyo dhammaan saldhigyada saldhigga ee ku dhex jira daboolka wireless-ka ee summada waxay heli doonaan signalka wireless-ka. Haddii laba saldhig oo saldhigeed oo la yaqaan dhibcaha isku-dubarid ay helaan calaamadda oo masaafada u dhaxaysa taaga iyo labada saldhig ay kala duwan tahay, markaa dhibcaha wakhtiga ay labada saldhigba calaamaduhu helayaan way kala duwan yihiin.
Nidaamyada meelaynta wakhtiga ku-salaysan calaamadda, sida UWB, waxay u baahan yihiin in dib loo hawlgeliyo marka ay la kulmaan xidhidhaanshaha gidaarka. Isla aagga, tirada qolalka ayaa labanlaabmi doona, isticmaalka saldhigga saldhigga ayaa sidoo kale labanlaabmi doona. Way sahlanaan doontaa in la geeyo saldhigyada meelaha bannaan.
Warshadaha hadda isticmaalaya tignoolajiyada meelaynta UWB waa tunnel, dhirta kiimikaad, xabsiyada, isbitaalada, guryaha dadka lagu xanaaneeyo, miinooyinka, iyo warshado kale.
Isbarbardhigga farsamada meelaynta shabakada degaanka
Tiknoolajiyada meelaynta ee kor ku xusan ee ku salaysan shabakada degaanka ee wireless, oo ay ka mid yihiin, nidaamka meelaynta ultra-wideband, saxnaanta meelaynta guud ahaan waa ilaa heer sentimitir, laakiin kala duwan ee codsiga meelaynta noocan oo kale ah waa yar yahay, shabakadu waxay u baahan tahay in dib loo hawlgeliyo, iyo dadka isticmaala. Baahida loo qabo in la isticmaalo calaamado go'an, qalabka cabbiraadda ayaa leh kharash fulineed oo sarreeya. Inkasta oo saxnaanta hababka kale ee meelaynta ay waxoogaa ka sii xun tahay, kharashka sidoo kale wuu hooseeyaa. Guud ahaan, xoogga ishaarada waxaa loo isticmaalaa tixraac ahaan.
Noocyadan shabakadaha aagga wirelesska ah ayaa guud ahaan lagu isticmaalaa muuqaallada gudaha. Sababo la xiriira saameynta adag ee deegaanka gudaha, xoogga soo dhaweynta calaamaduhu si fudud ayay isu beddeli doontaa. Way adag tahay in la gaaro meeleyn sax ah iyadoo la adeegsanayo xoogga calaamadda oo keliya.
Sidaa darteed, iyadoo ku xiran cabbirrada cabbirka, meelaynta ayaa sidoo kale lagu gaari karaa iyadoo la adeegsanayo hab ku salaysan wakhtiga imaatinka calaamadda la helay iyo hab ku salaysan xagasha imaatinka calaamadda la helay.
Saddexda teknooloji ee Wi-Fi, Bluetooth iyo UWB, marka la eego saxnaanta meelaynta, UWB waxay gaari kartaa meelaynta heerka sentimitir, Bluetooth waa heerka sentimitir-ilaa mitir, Wi-Fi waa saxnaanta heerka mitirka; Marka la eego faragelinta, UWB aad ayey uga fiican tahay labada kale; xagga fogaanta gudbinta, Wi-Fi waa ka ugu fog, UWB waa labaad, iyo Bluetooth waa ka ugu gaaban; waxaa dheer; Marka la eego kharashka dhismaha, kharashka UWB aad ayuu uga sarreeyaa Wi-Fi iyo Bluetooth, Wi-Fi iyo Bluetooth ayaa awood u leh inay la falgalaan taleefannada casriga ah ee maanta; Marka la eego isticmaalka korontada, Bluetooth waxay isticmaashaa tamarta ugu yar, UWB waa labaad, iyo Wi-Fi waa kan ugu sarreeya. Haddii aan tixgelinno dhammaan arrimahan, Bluetooth waxay u badan tahay inay haysato fursad wanaagsan oo ay ku noqoto moodada cusub ee suuqa meelaynta gudaha, iyo tignoolajiyada kale waxay yeelan doonaan suuqyo u gaar ah.
