Ukuqatshelwa kweminwe, njengenye yeetekhnoloji ezininzi zokuchongwa kwebhayometriki, ikakhulu yenza ukusetyenziswa kweyantlukwano kwimizobo yolusu yeminwe yabantu, oko kukuthi, iinduli kunye neentlambo zokuthungwa.Ekubeni ipateni yoshicilelo lweminwe yomntu ngamnye, iindawo zokuqhawuka kunye neziphambuka zahlukile, , kwaye zihlala zingatshintshanga kubomi bonke, ngoko ke ukuqondwa kweminwe kuye kwaba yeyona nto isetyenziswayo kunye nobuchwephesha obuqolileyo phakathi kwetekhnoloji ezininzi zebhayometriki.Okwangoku, ukuqondwa kweminwe kuye kwasetyenziswa ngokubanzi kuphando lolwaphulo-mthetho, ukulwa nobunqolobi, ukhuseleko lwelizwe, ukuchasana neziyobisi, ukhuseleko loluntu, njl. njl. kwaye isetyenziswa ngokubanzi kwiifowuni eziphathwayo, iikhompyuter, ii-ATM, ulawulo lokufikelela kunye neenkqubo zewotshi kwimihla ngemihla. ubomi.
Umgaqo osebenzayo wokuqatshelwa kweminwe ikakhulu ubandakanya imisebenzi emithathu: ukufundwa kwemifanekiso yeminwe, ukukhupha iimpawu, kunye nokuthelekisa iminwe yeminwe.Iitekhnoloji eziqhelekileyo zokuqatshelwa kweminwe zezi: optical, capacitive, kunye ne-ultrasonic.
Ukuqaphela umnwe weminwe
Ukuqaphela iminwe yeminwe yitekhnoloji yokuqaphela iminwe enembali ende.Isebenzisa imigaqo ye-refraction yokukhanya kunye nokucamngca ukuchonga iminwe yeminwe.I-engile yerefraction yokukhanya okukhutshiweyo kwimigca engalinganiyo kumphezulu weminwe kunye nokukhanya kokukhanya okubonakalisiweyo kuya kwahluka, ngaloo ndlela kuqokelelwa ukukhanya okwahlukileyo kunye nenqanaba lobumnyama lolwazi lomfanekiso ukugqiba ingqokelela yeminwe.
Abafundi beminwe ye-Optical banemfuno eziphezulu zomthombo wokukhanya kunye noqhagamshelwano phakathi kweminwe kunye ne-sensor, kwaye ifuna uqhagamshelwano olulungileyo lweminwe kunye nokulungelelaniswa.Ke ngoko, iimodyuli zeminwe yeminwe zihlala zihlala kwindawo enkulu kwaye zineemfuno ezithile zobushushu kunye nokufuma, kwaye ukuchaneka kwayo akulunganga kakhulu.Inzuzo yale teknoloji kukuba yindleko ephantsi kwaye ifanelekile kwizicelo zokuqatshelwa kweminwe ngokubanzi, njengoomatshini bokuhamba beminwe.
Ukuqondwa kweminwe enobuchule
Ukuqondwa kweminwe enobuchule kunzima kakhulu kunokuqonda umnwe weminwe.Umgaqo wayo kukudibanisa ukuva uxinzelelo, i-capacitive sensing, i-thermal sensing kunye nezinye izinzwa kwi-chip.Xa i-fingerprint icinezela umphezulu we-chip, i-sensor ye-capacitive yangaphakathi iya kwenza umfanekiso weminwe ngokusekelwe kumahluko wentlawulo (okanye umahluko weqondo lokushisa) oveliswa yi-fingerprint crest kunye ne-trough, efuna unxibelelwano oluhle phakathi kweminwe kunye ne-sensor.
Inzuzo yokusebenzisa ukuqondwa kweminwe yecapacitive kukuba umgangatho womfanekiso uphezulu, ukugqwetheka kuncinci, kwaye umqondiso we-elektroniki uya kudlula elukhumbeni olufileyo kumphezulu womnwe, ngoko ke ukuqondwa komzimba ophilayo kunokwenziwa, okuphucula kakhulu ukhuseleko lokuqatshelwa kweminwe.Nangona kunjalo, ukuqondwa kweminwe yecapacitive nayo ineziphene zayo zendalo.Imifanekiso yeminwe yeminwe echanekileyo ifuna iinqununu eziphezulu ze-capacitive, eziza kwandisa kakhulu iindleko.Kwaye ngenxa yokuba i-capacitive fingerprint recognition ixhomekeke kwimiqolo kunye neentlambo zomnwe, ukuba ubuso bomnwe bungcolisekile ngokungcola okanye ukujuluka, kuya kutshintsha ulwazi lwe-texture ebusweni bomnwe, okukhokelela ekuqapheliseni okungalunganga.
Ukuqatshelwa kweminwe ye-ultrasonic
Ukuqaphela iminwe ye-ultrasonic bubuchwepheshe obutsha obusebenzisa amaza omsindo ukufumana ulwazi lweminwe.Inzwa ikhupha iipulses ze-ultrasonic, ezisasazekileyo kwaye zibonakaliswe xa zidibana neepatheni zeminwe.Inzwa ifumana isignali ye-ultrasonic ebonakalisiweyo kwaye ikhupha iimpawu zeminwe ngokuhlalutya utshintsho kwisignali.Abafundi beminwe ye-Ultrasonic banemfuno ezisezantsi zokunxibelelana phakathi kweminwe kunye nenzwa, ngoko banokusebenza xa kukho umgama othile ukusuka kumphezulu weminwe.Inzuzo yale teknoloji kukuchasana kwayo okukhulu nokungcola kunye nemikrwelo.Yindlela yokuchonga iminwe ethembisayo.Nangona kunjalo, ukuqatshelwa kweminwe ye-ultrasonic ayikho ngaphandle kweentsilelo zayo.Iindleko zokuqatshelwa kweminwe ye-ultrasonic iphezulu, kwaye ayiphenduli njenge-optical and capacitive fingerprint recognition.Kananjalo ayihambelani kakuhle neefilimu ezikhuselayo zezinye izinto, eziya kuthi zinciphise ukuqatshelwa kweminwe ye-ultrasonic.ukuchaneka.
Ithatyathwe kunye, i-optical, capacitive, kunye ne-ultrasonic fingerprint recognction zineenzuzo kunye neengxaki zazo.Ukuqatshelwa kweminwe yecapacitive ngoku yeyona nto isetyenziswa kakhulu, kodwa ukuqondwa kweminwe ye-ultrasonic kuneyona nto iphezulu yokhuseleko.Nangona ukuqondwa kweminwe yeminwe yeyona nto iphantsi kwindleko, inokhuseleko olubi kunye nokusebenza kokuqaphela.
I-Shenzhen Handheld-Wireless Technology Co, Ltd ibonelela ngokubamba izandla ezirhabaxa kunye neetafile ngoku ezixhasa umnwe weminwe, unokusebenziseka okuqinileyo kokusingqongileyo kunye nokuchasana nokukhohlisa okuphezulu.Zingasetyenziswa ngokubanzi kukhuseleko loluntu, ulawulo lokhuseleko loluntu, ukhuseleko, ulawulo lolawulo lokufikelela, njl.
