Njengoko sisazi, kumxholo we-Intanethi yeZinto, ukufunyanwa kunye nokusetyenziswa kolwazi lwendawo kuya kuba kubaluleke ngakumbi. Xa kuthelekiswa nokubekwa ngaphandle, indawo yokusebenza yendawo yangaphakathi inzima kwaye ithambile, kwaye itekhnoloji yayo yahluke kakhulu. Ngokomzekelo, abasebenzi befektri abahlakaniphile kunye nokulawulwa kwempahla kunye nokucwangciswa, ulawulo lokhuseleko lwemveliso, ukukhangela imoto yokupaka imoto ephantsi komhlaba, abasebenzi bezakhiwo ezihlakaniphile / ulawulo lokubeka iindwendwe, ukuhamba kwendawo yomboniso, njl.
Ngokubanzi, sinokwahlula itekhnoloji yokubeka yangaphakathi Wi-Fi indawo, indawo yeZigBee, indawo yeBluetooth, indawo ye-UWB, indawo yeRFID, indawo yesathelayithi, indawo ebangela isantya esisezantsi, indawo yesiseko sesikhululo, indawo yeacoustic, indawo yokubona, indawo yegeomagnetic, njl. njl. kwaye Bluetooth.
Imodyuli yeWi-Fi
Ukubekwa kwe-Wi-Fi kwaqala ukusetyenziswa kwindawo yokubeka iliso kubasebenzi ngokusekelwe kwiithegi zokubeka malunga no-2010. Ngo-2013, izicelo ezifana nokufunyanwa kwe-Wi-Fi ngokusekelwe kwiifowuni eziphathwayo nazo zavela.
Okwangoku, indawo ye-Wi-Fi yitekhnoloji ethandwayo yokubeka indawo yangaphakathi, kwaye indlela yokumisa isekelwe kwindlela yokwandisa amandla omqondiso kunye nendlela yokuqaphela umnwe weminwe.
Indlela yemodeli yosasazo yamandla omqondiso ibhekiselele ekusebenziseni imodeli ethile yokuphela kwetshaneli ecingelwayo kwimeko-bume yangoku ukuqikelela umgama phakathi kwetheminali kunye nendawo eyaziwayo ye-AP ngokobudlelwane bayo bemathematika. Ukuba umsebenzisi uva imiqondiso emininzi ye-AP, inokudlula kumacala amathathu Ukumisa i-algorithm ukufumana ulwazi lwendawo yomsebenzisi; indlela yokuchonga iminwe isekelwe kwiimpawu zokusasazwa kwesibonakaliso se-Wi-Fi, idatha yokufumanisa i-APs ezininzi idibaniswe nolwazi lweminwe, kwaye indawo enokwenzeka yento ehambayo iqikelelwa ngokuthelekisa neenkcukacha zereferensi.
Kwezinye iimeko apho ukuchaneka kokubeka kwinqanaba lemitha, i-Wi-Fi ingasetyenziselwa ukugubungela. Le teknoloji ifanelekile ukubeka kunye nokuhamba kwabantu / iimoto, amaziko onyango, iindawo zokuthenga, iipaki zemixholo, kunye nezinye iimeko.
Imodyuli yeBluetooth
Malunga ne-2014, itekhnoloji yokumisa esekwe kwiBluetooth yaqala ukusetyenziswa kwindawo yokubeka iliso kunye nokubeka.
NgoJulayi 2017, i-Bluetooth mesh yasungulwa ngokusemthethweni. Ngonyaka kunye nesiqingatha, ngaphezu kweemveliso ze-105 kunye nemisebenzi ye-Bluetooth mesh network ziye zaqinisekiswa, kubandakanywa iichips, i-protocol stacks, iimodyuli, kunye nabanikezeli bemveliso ye-terminal.
Ukuze kuhlangatyezwane nemfuno ekhulayo yenkonzo yenkonzo yendawo, umgangatho omtsha weBluetooth 5.1 wongeze umsebenzi wesalathiso, onokunceda isixhobo ukuba sicacise isalathiso somqondiso weBluetooth, kwaye emva koko uncede umphuhlisi ukuba atolike isisombululo seBluetooth sokusondela. isalathiso sesixhobo ukufumana indawo ye-centimeter-level echanekileyo yeBluetooth yokubeka inkqubo.
Izisombululo zenkonzo yeBluetooth ezisekelwe kwindawo zihlulwe ngokubanzi zibe ngamacandelo amabini: izisombululo ezikufutshane kunye neenkqubo zokubeka. Nokuba kukwindawo yexesha langempela okanye indawo yangaphakathi, umgaqo uyafana. Oko kukuthi, i-RSSI (amandla omqondiso afunyenweyo) yongezwa kwipakethi yokuhanjiswa kwepakethi yedatha, kwaye uluhlu olusondeleyo lwemveliso luyinyani nge-RSSI. I-algorithm yokulinganisa, kwaye ekugqibeleni ugqibezele ukuma kwangaphakathi.
Ukuma kweBluetooth, okoko nje isixhobo seBluetooth sivuliwe, ungasifumana. Ngokukhutshwa kwe Bluetooth 5.x kunye nee-smartphones / iipads / iilaptops ezininzi ezidityaniswa neBluetooth, iBluetooth kulindeleke ukuba ithathe isabelo esikhulu ngakumbi kwimarike yenkonzo esekwe kwindawo. Ngokutsho kwe-"2019 Bluetooth Market Update", iinkonzo zendawo ziye zaba sisisombululo seBluetooth esikhula ngokukhawuleza, kwaye izinga layo lokukhula ngonyaka kulindeleke ukuba lifike kwi-43% kwiminyaka emihlanu ezayo.
Ukubekwa kweBluetooth kusetyenziselwa ukumisa abantu/impahla yexabiso elikhulu nakwizinga elikhulu, ezinje ngeeholo ezinomgangatho omnye okanye iivenkile, iiholo zemiboniso, amabala emidlalo, iindawo zokugcina iimpahla, iifektri.
I-UWB
Kwiminyaka yakutshanje, njengoko izisombululo ze-chip ye-UWB zikhulile kwaye iindleko ziye zawa, iinkampani zasekhaya ezifunda iteknoloji yokubeka i-UWB ziye zavela. I-UWB iteknoloji yokumisa i-wireless enezinga eliphezulu lokudluliselwa (ukuya kwi-1000Mbps okanye ngaphezulu), amandla okuhambisa aphantsi kunye nokukwazi ukungena okunamandla.
Ukubekwa kwe-UWB yi-multi-sensor usebenzisa i-TDOA (ixesha lokuFika kweXesha, ixesha lokufika) kunye ne-AOA yokubeka i-algorithm yokuhlalutya indawo yelebula, kunye nesisombululo seendlela ezininzi, ukuchaneka okuphezulu, ukuchaneka kwendawo kunokufikelela kwinqanaba le-centimeter kunye nezinye iimpawu.
I-TDOA yindlela yokubeka usebenzisa umahluko wexesha lokufika, okwabizwa ngokuba yi-hyperbolic positioning. Ikhadi lethegi lithumela umqondiso we-UWB ngaphandle, kwaye zonke izikhululo ezisisiseko ngaphakathi kwe-wireless coverage yethegi ziya kufumana isignali engenazingcingo. Ukuba izikhululo ezibini ezisisiseko ezinamanqaku olungelelwaniso awaziwayo zifumana umqondiso kunye nomgama phakathi kwethegi kunye nezikhululo ezibini ezisisiseko zahlukile, ngoko ke amaxesha apho izikhululo ezibini ezisisiseko zifumana khona umqondiso ziyahluka.
Iisistim zokumisa ezisekwe kwixesha leSiginali, ezifana ne-UWB, kufuneka ziphinde zisetyenziswe xa zidibana nokuvaleka eludongeni. Kwindawo efanayo, inani lamagumbi liya kuphinda kabini, kwaye ukusetyenziswa kwesikhululo sesiseko kuya kuphinda kabini. Kuya kuba lula ukuhambisa izikhululo ezisisiseko kwiindawo ezivulekileyo.
Amashishini ngoku asebenzisa itekhnoloji yokubeka i-UWB ngamatonela, izityalo zemichiza, iintolongo, izibhedlele, amakhaya abongikazi, imigodi, kunye namanye amashishini.
Ukuthelekiswa kobuchwephesha bokubeka indawo kwinethiwekhi yendawo
Ubuchwephesha bokumisa obukhankanywe ngasentla obusekwe kuthungelwano lwendawo engenazingcingo, phakathi kwabo, inkqubo yokubeka i-Ultra-wideband, ukuchaneka kokumiswa ngokubanzi ukuya kuthi ga kwinqanaba leesentimitha, kodwa uluhlu lwesicelo sokumisa olunjalo luncinci, inethiwekhi kufuneka iphinde isetyenziswe, kunye nabasebenzisi. Isidingo sokusebenzisa imiqondiso ezinikeleyo, isixhobo sokulinganisa sineendleko eziphezulu zokuphunyezwa. Nangona ukuchaneka kwezinye iindlela zokubeka kumbi kancinane, iindleko nazo ziphantsi. Ngokuqhelekileyo, amandla omqondiso asetyenziswa njengesalathiso.
Olu hlobo lothungelwano lwengingqi olungenazingcingo lusetyenziswa ngokubanzi kwimiboniso yangaphakathi. Ngenxa yempembelelo enzima yendawo yangaphakathi, amandla okufumana umqondiso aya kuguquguquka ngokulula. Kunzima ukufezekisa indawo echanekileyo usebenzisa amandla omqondiso kuphela.
Ngoko ke, kuxhomekeke kwiiparamitha zokulinganisa, ukubeka indawo kunokufezekiswa ngokusebenzisa indlela esekelwe kwixesha lokufika komqondiso ofunyenweyo kunye nendlela esekelwe kwi-angle yokufika komqondiso ofunyenweyo.
Ubuchwephesha obuthathu be-Wi-Fi, iBluetooth kunye ne-UWB, ngokuchaneka kokubeka, i-UWB inokufikelela kwindawo yezinga le-centimeter-level, i-Bluetooth inqanaba le-centimeter-to-meter level, kunye ne-Wi-Fi kuphela ukuchaneka komgangatho wemitha; Ngokumalunga nokuphazamiseka, i-UWB ingcono kakhulu kunezinye ezimbini; ngokomgama wothumelo, iWi-Fi yeyona ikude, i-UWB yeyesibini, kwaye iBluetooth yeyona imfutshane; Ukwengeza; Ngokumalunga neendleko zokwakha, iindleko ze-UWB ziphezulu kakhulu kune-Wi-Fi kunye neBluetooth, i-Wi-Fi kunye neBluetooth zikwazi kangcono ukusebenzisana nee-smartphones zanamhlanje; Ngokuphathelele ukusetyenziswa kwamandla, iBluetooth isebenzisa amandla amancinci, i-UWB yeyesibini, kwaye i-Wi-Fi iphezulu. Ukuba siqwalasela zonke ezi zinto, iBluetooth inokuba nethuba elihle lokuba yifashoni entsha kwimarike yendawo yangaphakathi, kwaye obunye ubuchwephesha buya kuba nezabo iimarike.
