Itekhnoloji esele isetyenziswa ngokuqhelekileyo ngaphakathi endlini ibandakanya itekhnoloji ye-ultrasonic, itekhnoloji ye-infrared, i-ultra-wideband (UWB), isazisi samaza kanomathotholo (RFID), iZig-Bee, iWlan, ukulandelela okubonakalayo kunye nokubeka indawo, indawo yonxibelelwano ngeselula, indawo yeBluetooth, kunye ne-geomagnetic positioning.
Ukubekwa kwe-Ultrasound
Ukuchaneka kokubekwa kwe-Ultrasound kunokufikelela kwiisentimitha, kodwa i-ultrasonic attenuation ibalulekile, ichaphazela uluhlu olusebenzayo lokubeka.
Ukuma kwe-infrared
Ukuma kwe-infrared ukuchaneka kunokufikelela kwi-5 ~ 10 m. Nangona kunjalo, ukukhanya kwe-infrared kuvalwe ngokulula ngezinto okanye iindonga kwinkqubo yokuhambisa, kwaye umgama wokuhambisa umfutshane. Inkqubo yokubeka inobunzima obuphezulu kwaye ukusebenza kunye nokusebenza zisahluka kobunye ubugcisa.
UWB indawo
Ukuma kwe-UWB, ukuchaneka ngokuqhelekileyo akukho ngaphezu kwe-15 cm. Nangona kunjalo, ayikavuthwa. Eyona ngxaki iphambili kukuba inkqubo ye-UWB ikwi-bandwidth ephezulu kwaye inokuphazamisana nezinye iisistim zonxibelelwano ezingenazingcingo.
RFID indawo yangaphakathi
I-RFID yokubeka indawo yangaphakathi echanekileyo yi-1 ukuya kwi-3 m. Ukungalungi zezi: umthamo wokuchongwa uncinci, ufuna isixhobo esithile sokuchonga, indima yomgama, ayinakho unxibelelwano, kwaye akukho lula ukudibanisa kwezinye iinkqubo.
Ukubekwa kweZigbee
Ukuchaneka kokubeka itekhnoloji yeZigbee kunokufikelela kwiimitha. Ngenxa yobume bendawo yangaphakathi entsonkothileyo, kunzima kakhulu ukuseka imodeli echanekileyo yokusasaza. Ke ngoko, ukuchaneka kokubeka itekhnoloji yeZigBee kulinganiselwe kakhulu.
Ukubekwa kweWLAN
Ukuchaneka kokubeka iWLAN kunokufikelela kwi-5 ukuya kwi-10 m. Inkqubo yokubeka i-WiFi inezingeloncedo ezifana neendleko eziphezulu zokufakela kunye nokusetyenziswa kwamandla amakhulu, okuthintela ukuthengiswa kweteknoloji yokubeka ngaphakathi. Ukuchaneka kwendawo jikelele yokubeka ukukhanya kokulandelela ukukhanya yi-2 ukuya kwi-5 m. Nangona kunjalo, ngenxa yeempawu zayo, ukufezekisa itekhnoloji ye-optical positioning echanekileyo, kufuneka ixhotyiswe ngee-sensor optical, kwaye i-sensor ye-directivity iphezulu. Ukuchaneka kokubeka unxibelelwano lweselula aluphezulu, kwaye ukuchaneka kwayo kuxhomekeke ekusasazweni kwezikhululo zesiseko esihambahambayo kunye nobukhulu bokugubungela.
Ukuchaneka kokumiswa kwe indawo ye-geomagnetic ingcono kune-30 m. Izinzwa zemagneti zezona zinto ziphambili ezimisela ukujongwa kwe-geomagnetic kunye nokuma. Iimephu ezichanekileyo zesalathiso sommandla wemagnethi kunye nolwazi oluthembekileyo oluhambelana ne-algorithms nazo zibaluleke kakhulu. Iindleko eziphezulu ze-geomagnetic sensors ezichanekileyo zithintela ukuthandwa kwe-geomagnetic positioning.
Ukubekwa kweBluetooth
Itekhnoloji yokumisa iBluetooth ilungele ukulinganisa imigama emifutshane kunye nokusetyenziswa kwamandla aphantsi. Isetyenziswa kakhulu kwindawo encinci yokubeka ngokuchaneka kwe-1 ukuya kwi-3 m, kwaye inokhuseleko oluphakathi kunye nokuthembeka. Izixhobo zeBluetooth zincinci ngobukhulu kwaye kulula ukuzidibanisa kwiiPDA, iiPC, kunye neeselfowuni, ngoko ke zithandwa ngokulula. Kubathengi abadibanise izixhobo eziphathwayo zeBluetooth, nje ukuba umsebenzi weBluetooth wesixhobo uvuliwe, inkqubo yokubeka iBluetooth yangaphakathi inokugqiba indawo. Xa usebenzisa le teknoloji kwindawo yokubeka umgama omfutshane wangaphakathi, kulula ukufumana isixhobo kwaye ukuhanjiswa kwesignali akuchatshazelwa ngumgca wokubona. Xa kuthelekiswa nezinye iindlela ezidumileyo zokubeka ngaphakathi endlini, kusetyenziswa amandla aphantsi eBluetooth 4. 0 Indlela yokubeka esemgangathweni yangaphakathi ineempawu zeendleko eziphantsi, iskim esilula sokusasaza, impendulo ekhawulezayo kunye nezinye iimpawu zobugcisa, kunye nabavelisi besixhobo esiphathwayo seBluetooth 4. 0 ukukhuthazwa kokuchazwa komgangatho kukhokelele kumathuba angcono ophuhliso.
Ukusukela ekubhengezweni komgangatho weBluetooth 1, kuye kwakho iindlela ezahlukeneyo ezisekwe kwitekhnoloji yeBluetooth yokumiswa kwangaphakathi, kubandakanya indlela esekwe kubhaqo loluhlu, indlela esekwe kwimodeli yosasazo lomqondiso, kunye nendlela esekwe kungqamaniso lweminwe. . Indlela esekelwe kuluhlu lokuchongwa lunokuchaneka kokubeka okuphantsi kunye nokuchaneka kwendawo yi-5 ~ 10 m, kwaye indawo echanekileyo malunga ne-3 m ngokusekelwe kwimodeli yosasazo lomqondiso, kunye nokuchaneka kwendawo esekelwe kwintsimi yokulinganisa iminwe yeminwe yi-2 ~ 3. m.
Ukubekwa kwebhakana
Ii-iBeacons zisekelwe kwiBluetooth 4.0 BLE (iBluetooth Low Energy). Ngokukhutshwa kwetekhnoloji ye-BLE kwiBluetooth 4.0 kunye ne-Apple's derivation eyomeleleyo, izicelo ze-iBeacons ziye zaba yeyona teknoloji ishushu. Kule mihla, ii-hardware ezininzi ezihlakaniphile sele ziqalisile ukuxhasa ukusetyenziswa kwe-BLE, ngakumbi kwiifowuni eziphathwayo ezisanda kufakwa kuluhlu, kwaye i-BLE iye yaba luqwalaselo oluqhelekileyo. Ke ngoko, ukusetyenziswa kwetekhnoloji ye-BLE yokubeka indawo yangaphakathi yeefowuni eziphathwayo ibe yindawo eshushu yezicelo ze-LBS zangaphakathi. Kwindlela yokumisa iBluetooth, indlela esekwe kumandla entsimi ukuthelekisa iminwe inokona kuphezulu kwaye isetyenziswa ngokubanzi.
