Tiknoolajiyada meelaynta gudaha ee sida caadiga ah loo isticmaalo waxaa ka mid ah tignoolajiyada ultrasonic, tignoolajiyada infrared, ultra-wideband (UWB), aqoonsiga soo noqnoqda raadiyaha (RFID), Zig-Bee, Wlan, goobaynta indhaha iyo meelaynta, meelaynta isgaarsiinta mobilada, meelaynta Bluetooth, iyo meelaynta geomagnetic.
Meelaynta Ultrasound
Saxnaanta meelaynta Ultrasound waxay gaari kartaa sentimitir, laakiin attenuation ultrasonic waa mid muhiim ah, taasoo saameynaysa kala duwanaanshaha wax ku oolka ah ee meelaynta.
Meelaynta infrared
Meelaynta infrared saxnaanta waxay gaari kartaa 5 ~ 10 m. Si kastaba ha ahaatee, iftiinka infrared ayaa si fudud u xannibaya walxaha ama derbiyada habka gudbinta, masaafada gudbintuna waa gaaban tahay. Nidaamka meelaynta ayaa leh heer aad u sarreeya oo kakanaanta iyo waxtarka iyo waxtarka ayaa weli ka duwan tignoolajiyada kale.
Meelaynta UWB
Meelaynta UWB, saxnaanta badanaa kama badna 15 cm. Si kastaba ha ahaatee, weli ma qaan gaarin. Dhibka ugu weyni waa in nidaamka UWB uu ku jiro xaddi sare oo xad dhaaf ah waxaana laga yaabaa inuu farageliyo nidaamyada kale ee isgaarsiinta wireless-ka.
Meelaynta gudaha RFID
Saxnaanta meelaynta gudaha RFID waa 1 ilaa 3 m. Khasaarooyinku waa: mugga aqoonsiga waa mid yar, wuxuu u baahan yahay qalab aqoonsi oo gaar ah, doorka masaafada, ma laha awood isgaarsiineed, mana fududa in lagu dhex daro nidaamyada kale.
Meelaynta Zigbee
Saxnaanta meelaynta tignoolajiyada Zigbee waxay gaari kartaa mitir. Sababtoo ah jawiga gudaha ee adag, aad bay u adagtahay in la sameeyo qaab faafin sax ah. Sidaa darteed, saxnaanta meelaynta tignoolajiyada meelaynta ZigBee aad bay u xaddidan tahay.
meelaynta WLAN
Saxnaanta meelaynta WLAN waxay gaari kartaa 5 ilaa 10 mitir. Nidaamka meelaynta WiFi wuxuu leeyahay faa'iido darrooyin sida kharashka rakibaadda oo sarreeya iyo isticmaalka awoodda badan, taas oo caqabad ku ah ganacsiga tignoolajiyada meelaynta gudaha. Saxnaanta guud ee meelaynta meelaynta iftiinka iftiinka waa 2 ilaa 5 m. Si kastaba ha noqotee, iyada oo ay ugu wacan tahay sifooyinkeeda gaarka ah, si loo gaaro tignoolajiyada meelaynta indhaha ee saxda ah, waa in lagu qalabeeyaa dareemayaasha indhaha, iyo jiheynta dareemedu waa mid sare. Saxnaanta meelaynta isgaadhsiinta mobaylada ma aha mid sare, saxnimadeeduna waxay ku xidhan tahay qaybinta saldhigyada mobilada iyo baaxada daboolida.
Saxnaanta meelaynta ee meelaynta geomagnetic ayaa ka fiican 30 m. Dareemayaasha magnetic waa qodobbada muhiimka ah ee go'aaminaya navigation geomagnetic iyo meelaynta. Khariidadaha tixraaca goobta magnetic deegaanka ee saxda ah iyo algoorithms-yada u dhigma macluumaadka magnetka ee la isku halayn karo ayaa sidoo kale aad muhiim u ah. Qiimaha sare ee dareemayaasha geomagnetic ee saxda ah ayaa horjoogsanaya caannimada meelaynta geomagnetic.
Meelaynta Bluetooth
Tiknoolajiyada meelaynta Bluetooth waxay ku habboon tahay cabbirida masaafooyinka gaaban iyo isticmaalka tamarta yar. Inta badan waxaa lagu dabaqaa meelaynta cabbir yar oo sax ah 1 ilaa 3 m, waxayna leedahay ilaalin dhexdhexaad ah iyo isku hallayn. Aaladaha Bluetooth-ku cabbirkoodu waa yar yahay waana sahlan tahay in lagu dhex geliyo PDA-yada, PC-yada, iyo talefannada gacanta, sidaa awgeed si fudud ayaa loo faafiyey. Macaamiisha isku daray aaladaha mobilada ee ku shaqeeya Bluetooth, ilaa inta shaqada Bluetooth ee aaladda ay shaqaynayso, nidaamka meelaynta gudaha ee Bluetooth ayaa go'aamin kara meesha. Markaad isticmaalayso tignoolajiyadan meelaynta fogaanta gudaha gudaha, way fududahay in la ogaado aaladda iyo gudbinta calaamaduhu ma saameynayso khadka-aragga. Marka la barbar dhigo dhowr hababka meelaynta gudaha ee caanka ah, iyadoo la adeegsanayo Bluetooth-ka awood yar 4. kor u qaadista qeexitaanka heerka ayaa horseeday rajooyin horumarineed oo wanaagsan.
Tan iyo markii la faafiyay heerka Bluetooth 1, waxaa jiray habab kala duwan oo ku saleysan tignoolajiyada Bluetooth ee meeleynta gudaha, oo ay ku jiraan habka ku saleysan ogaanshaha baaxadda, habka ku saleysan qaabka faafinta calaamadaha, iyo habka ku saleysan isbarbardhigga faraha goobta. . Habka ku salaysan qiyaasta qiyaasta ayaa leh saxnaanta meelaynta hoose iyo saxnaanta meelaynta waa 5 ~ 10 m, iyo saxnaanta goobta waxay ku saabsan tahay 3 m oo ku salaysan qaabka faafinta calaamadaha, iyo saxnaanta goobta oo ku salaysan xoojinta faraha goobta waa 2 ~ 3 m.
Beacon meelaynta
iBeacons waxay ku salaysan yihiin Bluetooth 4.0 BLE (Bluetooth Low Energy). Marka la sii daayo tignoolajiyada BLE ee Bluetooth 4.0 iyo soo saarista xooggan ee Apple, codsiyada iBeacons waxay noqdeen tignoolajiyada ugu kulul. Maalmahan, qalabyo badan oo casri ah ayaa bilaabay inay taageeraan codsiga BLE, gaar ahaan taleefannada gacanta ee dhawaanta liiska, iyo BLE waxay noqotay qaabaynta caadiga ah. Sidaa darteed, adeegsiga tignoolajiyada BLE meelaynta gudaha talefannada gacanta waxay noqotay meel kulul codsiyada gudaha LBS. Habka meelaynta Bluetooth-ka, habka ku salaysan isbarbardhigga faraha xoogga goobta ayaa leh saxnaanta ugu sareysa waxaana si ballaaran loo adeegsadaa.
