Njengoba sazi, kumongo we-inthanethi Yezinto, ukutholwa kanye nokusetshenziswa kolwazi lwendawo kuya ngokuya kubaluleke kakhulu. Uma kuqhathaniswa nokuma kwangaphandle, indawo yokusebenza yendawo yangaphakathi iyinkimbinkimbi futhi intekenteke, futhi ubuchwepheshe bayo buhluke kakhulu. Isibonelo, izisebenzi zasefekthri ezihlakaniphile nokuphathwa nokuhlelwa kwempahla, ukuphathwa kokuphepha kokukhiqiza, ukuzulazula kokusesha kwemoto yokupaka ngaphansi komhlaba, izisebenzi zebhilidi elihlakaniphile/ukuphathwa kokubekwa kwezivakashi, ukuzulazula kwendawo yombukiso, njll.
Ngokuvamile, singahlukanisa ubuchwepheshe bokubeka endlini kube Wi-Fi ukuma, ukuma kwe-ZigBee, ukuma kwe-Bluetooth, ukuma kwe-UWB, ukuma kwe-RFID, ukuma kwesathelayithi, ukuma kwe-trigger ye-low-frequency, ukuma kwesiteshi, ukuma kwe-acoustic, ukuma kwe-optical, ukuma kwe-geomagnetic, njll. Ake sixoxe ngobuchwepheshe obuthathu obujwayelekile bokumisa endlini be-WiFi, UWB futhi Bluetooth.
Imojula ye-Wi-Fi
Ukubekwa kwe-Wi-Fi kwaqala ukusetshenziswa emkhakheni wokuqapha abasebenzi okusekelwe kumathegi okumisa ngawo unyaka ka-2010. Ngo-2013, izinhlelo zokusebenza ezifana nokutholwa kwe-Wi-Fi ngokusekelwe kumakhalekhukhwini nazo zavela.
Njengamanje, ukubeka i-Wi-Fi kuwubuchwepheshe obudumile bokubeka endlini, futhi indlela yakho yokumisa isekelwe endleleni yemodeli yokusakaza amandla esignali kanye nendlela yokubona izigxivizo zeminwe.
Indlela yemodeli yokusabalalisa amandla esignali ibhekisela ekusebenziseni imodeli ethile yokufiphala yesiteshi ecatshangwa endaweni yamanje ukuze kulinganiswe ibanga phakathi kwetheminali nendawo eyaziwayo ye-AP ngokuvumelana nobudlelwano bayo bezibalo. Uma umsebenzisi ezwa amasignali amaningi e-AP, angadlula ezinhlangothini ezintathu ze-Positioning algorithm ukuze athole ulwazi lwendawo yomsebenzisi; Indlela yokuhlonza izigxivizo zeminwe isekelwe kuzici zokusakaza zesignali ye-Wi-Fi, idatha yokuthola yama-AP amaningi ihlanganiswa ibe ulwazi lwezigxivizo zeminwe, futhi indawo engaba khona yento ehambayo ilinganiselwa ngokuqhathanisa nedatha yereferensi.
Kwezinye izimo lapho ukunemba kokuma kuyileveli yemitha, i-Wi-Fi ingasetshenziselwa ukufakwa. Lobu buchwepheshe bufanele ukubekwa nokuzulazula kwabantu/izimoto, izikhungo zezokwelapha, izinxanxathela zezitolo, amapaki etimu, nezinye izimo.
Imodyuli yeBluetooth
Cishe ngo-2014, ubuchwepheshe bokumisa obusekelwe ku-Bluetooth baqala ukusetshenziswa emkhakheni wokuqapha nokubeka indawo.
NgoJulayi 2017, i-Bluetooth mesh yethulwa ngokusemthethweni. Onyakeni nohhafu, imikhiqizo engaphezu kwe-105 enenethiwekhi ye-Bluetooth mesh isiqinisekisiwe, okuhlanganisa ama-chips, izitaki zephrothokholi, amamojula, nabahlinzeki bemikhiqizo yetheminali.
Ukuze kuhlangatshezwane nesidingo esikhulayo semakethe yesevisi yendawo, izinga elisha le-Bluetooth 5.1 lengeze umsebenzi wokuqondisa, ongasiza idivayisi ukucacisa isiqondiso sesignali ye-Bluetooth, bese sisize unjiniyela ukuthi ahumushe isisombululo se-Bluetooth sokusondela isiqondiso sedivayisi ukuze kuzuzwe indawo yezinga lesentimitha Uhlelo lokumisa olunembile lwe-Bluetooth.
Izixazululo zesevisi ye-Bluetooth ezisekelwe endaweni ngokuvamile zihlukaniswa izigaba ezimbili: izixazululo eziseduze kanye nezinhlelo zokubeka indawo. Kungakhathaliseki ukuthi ukuma ngesikhathi sangempela noma ukuma kwangaphakathi, isimiso siyefana. Okusho ukuthi, indlela ye-RSSI (amandla esignali atholiwe) yengezwa ekudluliselweni kwephakethe ledatha, futhi ububanzi bomkhiqizo bufinyelelwa nge-RSSI. I-algorithm yokulinganisa, futhi ekugcineni uqedele ukuma kwangaphakathi.
Ukuma kwe-Bluetooth, inqobo nje uma umsebenzi we-Bluetooth wedivayisi uvuliwe, ungawuthola. Ngokukhululwa kwe I-Bluetooth 5.x kanye nama-smartphone/amaphedi/amakhompyutha aphathekayo amaningi amaningi ahlanganisa ne-Bluetooth, i-Bluetooth kulindeleke ukuthi ithathe isabelo esikhulu kakhulu emakethe yesevisi esekelwe endaweni. Ngokuvumelana ne "2019 Bluetooth Market Update", izinsiza zendawo seziphenduke isixazululo se-Bluetooth esikhula ngokushesha, futhi izinga layo lokukhula elihlanganisiwe lonyaka kulindeleke ukuthi lifinyelele ku-43% eminyakeni emihlanu ezayo.
I-Bluetooth positioning isetshenziselwa kokubili indawo encane nenkulu yabantu/impahla, njengamahholo anesitezi esisodwa noma izitolo, amahholo emibukiso, izinkundla, izindawo zokugcina izimpahla, izimboni.
I-UWB
Eminyakeni yamuva nje, njengoba izixazululo ze-chip ye-UWB sezikhulile futhi nezindleko zehlile, izinkampani zasekhaya ezifunda ubuchwepheshe bokubeka i-UWB ziye zavela. I-UWB iwubuchwepheshe bokumisa okungenantambo obunezinga eliphezulu lokudlulisela (kufika ku-1000Mbps noma ngaphezulu), amandla okudlulisa aphansi namandla okungena aqinile.
Ukuma kwe-UWB kuyinzwa eminingi esebenzisa i-TDOA (Umehluko Wesikhathi Wokufika, isikhathi sokufika umehluko) kanye ne-algorithm yokubeka ye-AOA ukuze kuhlaziywe indawo yelebula, ngokulungiswa kwezindlela eziningi, ukunemba okuphezulu, ukunemba kokuma kungafinyelela izinga lesentimitha nezinye izici.
I-TDOA iyindlela yokuma usebenzisa umehluko wesikhathi sokufika, owaziwa nangokuthi ukuma kwe-hyperbolic. Ikhadi lethegi lithumela isignali ye-UWB ngaphandle, futhi zonke iziteshi eziyisisekelo ngaphakathi kokufakwa okungenantambo kwethegi zizothola isignali engenantambo. Uma iziteshi ezimbili eziyisisekelo ezinamaphoyinti aziwayo wokudidiyela zithola isignali kanye nebanga phakathi komaka kanye neziteshi ezimbili eziyisisekelo lihlukile, khona-ke amaphoyinti esikhathi lapho iziteshi ezimbili eziyisisekelo zithola khona isignali ahlukile.
Amasistimu wokuma asuselwa kusikhathi esignali, afana ne-UWB, adinga ukuphinda asetshenziswe uma ehlangabezana nokuvaleka kodonga. Endaweni efanayo, inani lamakamelo lizophinda kabili, futhi ukusetshenziswa kwesiteshi sesisekelo nakho kuzophindeka kabili. Kuzoba lula ukufaka iziteshi eziyisisekelo ezindaweni ezivulekile.
Izimboni ezisebenzisa ubuchwepheshe bokubeka i-UWB njengamanje ziyimigudu, izitshalo zamakhemikhali, amajele, izibhedlela, amakhaya asebekhulile, izimayini, nezinye izimboni.
Ukuqhathaniswa kobuchwepheshe bokubeka indawo kwenethiwekhi yendawo
Ubuchwepheshe bokumisa obalulwe ngenhla obusekelwe kunethiwekhi yendawo engenantambo, phakathi kwabo, isistimu yokumisa i-ultra-wideband, ukunemba kokumisa ngokuvamile kufika ezingeni lesentimitha, kodwa uhla lwesicelo sokuma olunjalo luncane, inethiwekhi idinga ukuphinda isetshenziswe, kanye nabasebenzisi. isidingo sokusebenzisa amasiginali azinikezele, okokusebenza kokulinganisa kunezindleko eziphakeme zokuqalisa. Nakuba ukunemba kwezinye izindlela zokubeka kubi kakhulu, izindleko nazo ziphansi. Ngokuvamile, amandla esignali asetshenziswa njengereferensi.
Lezi zinhlobo zamanethiwekhi wendawo angenazintambo ngokuvamile zisetshenziswa ezigcawini zasendlini. Ngenxa yethonya eliyinkimbinkimbi lendawo yasendlini, amandla okwamukela isignali azoguquguquka kalula. Kunzima ukufeza ukuma okunembile usebenzisa amandla esignali kuphela.
Ngakho-ke, kuye ngamapharamitha wokulinganisa, ukubeka indawo kungabuye kufezwe kusetshenziswa indlela esekelwe esikhathini sokufika kwesignali eyamukelwe kanye nendlela esekelwe ku-angle yokufika kwesignali eyamukelwe.
Ubuchwepheshe obuthathu be-Wi-Fi, i-Bluetooth ne-UWB, mayelana nokunemba kokubeka indawo, i-UWB ingafinyelela ukuma kwezinga lesentimitha, i-Bluetooth iyileveli yesentimitha ukuya kumitha, kanti i-Wi-Fi iwukunemba kwezinga lemitha kuphela; Mayelana nokuphazamiseka, i-UWB ingcono kakhulu kunezinye ezimbili; ngokwebanga lokudlulisela, i-Wi-Fi ikude kakhulu, i-UWB ingeyesibili, kanti i-Bluetooth yimfushane kakhulu; Ngaphezu kwalokho; Mayelana nezindleko zokwakha, izindleko ze-UWB ziphezulu kakhulu kune-Wi-Fi futhi i-Bluetooth, i-Wi-Fi ne-Bluetooth zikwazi kangcono ukuxhumana nama-smartphones anamuhla; Mayelana nokusetshenziswa kwamandla, i-Bluetooth isebenzisa amandla amancane, i-UWB ingeyesibili, kanti i-Wi-Fi iphezulu kakhulu. Uma sicabangela zonke lezi zici, i-Bluetooth ingase ibe nethuba elihle lokuba imfashini entsha emakethe yendawo yasendlini, futhi obunye ubuchwepheshe buzoba nezimakethe zabo.
