Zeminwe scanner njengendlela uqinisekiso lomsebenzisi

Ukuza kuthi ga ngoku, le computerization yoluntu kwenza sijonge iindlela ezahlukeneyo ukunciphisa ukufikelela ulwazi egcinwe kwi computer. Ngaphezu koko, ugunyaziso lomsebenzisi kunye nenkqubo uqinisekiso nephasiwedi yenye ixhaphakileyo, noxa kuneengxaki ezininzi. Elinye kukhuseleko lokugqitha inokuba umsebenzisi uqinisekiso wasungula parameters, ezifana zeminwe. Kwaye kuthatha nje vuavanyisi weminwe kunye software ezinxulumene, nto leyo iza ngefoni.

Yintoni na le vuavanyisi weminwe

isikeni zeminwe isixhobo elifundeka umfanekiso womwe zonke iimpawu zayo ngendlela limwe, kwaye edlulisela umphumo scan ukuya software. isicelo ezizodwa uthelekisa umfanekiso kunye imodeli obuyiyile ibakala lokugqitha wasungula.

Types of yabavavanyi fingerprint

Zonke yabavavanyi fingerprint, ezisetyenziswa ngoku, ukuze zihlelwe ngokwamaqela amathathu, zisekelwe kumgaqo ebonakalayo yokusebenza:

- semiconductor (electronic);

- Optical;

- ultrasound.

yabavavanyi semiconductor

Olu hlobo isithwebuli ufumana umfanekiso ngokusekelwe kwiipropati semiconductor ukuba utshintshe kwinkalo qhagamshelana lwemifanekiso pamwe kunye isithwebuli. Ukusebenza kolu hlobo ayisuse uya kulala ubugcisa ezininzi:

- Capacitive yabavavanyi. Ukusebenza yabavavanyi ezinjalo isiphumo ukuba amandla kwi PN-utshintsho isixhobo semiconductor yahluka phezu emile weminwe zoqhagamshelwano kunye iziqalelo semiconductor ye matrix.

- a yabavavanyi uxinzelelo-onovakalelo. Zeminwe scanner yale hlobo esebenza usebenzisa uluhlu ekhethekileyo lweziqalelo piezoelectric. Xa Ucikicane wadibana isizalo, ikhephu abeke uxinzelelo phezu kwakhe, nokudandatheka, ngokulandelelanayo, akukho. Ngokusekelwe ingcinezelo ebangelwa isizalo, nomfanekiso kwakheka.

- Thermo-yabavavanyi. ayisuse le hlobo baba abenzi boluvo babesebenzisa eziquka izinto pyroelectric. Ezi abenzi boluvo ingxelo umahluko ubushushu, emva kokuba iguqulelwa ibe ombane.

- yabavavanyi RF. Yabavavanyi yale hlobo luqulathe mikroantenn ukuba ukujikelezisa uphawu obuthathaka, yaye ukuphendula kwixabiso weminwe efunyenwe amandla electro-isizathu esabangela umfanekiso fingerprint lokugqibela.

- Indlela Yokutshayelela thermo-yabavavanyi. Efanayo thermo-yabavavanyi. Umahluko kuphela kukuba kufuneka ubambe umnwe wakho phezu komhlaba ukuskena, kwaye ayisebenzi nto.

- Capacitive isithwebuli efakwa. Ithekhnoloji for ukuvelisa umfanekiso womwe iyafana kwi capacitance, kodwa indlela yokulungiselela ungachazwa ukuba ngomnwe okwenzelwa kumphezulu isixhobosovavanyo lwemifanekiso.

- RF isithwebuli efakwa. Umgaqo esebenza ngayo ezi zixhobo kuyafana njengakwi izixhobo radio-rhoqo, kodwa indlela yokususa umfanekiso isicelo iminwe ukuya kwisixhobo, kwaye ubambe umnwe wakho kuyo kumphezulu wayo.

yabavavanyi nabizayo

Zeminwe scanner yale hlobo ifumana image umnwe ngokusebenzisa indlela optical. Ukusebenza iingcinga olu hlobo are ubugcisa ezahlukeneyo

- FTIR-yabavavanyi. Ezi zixhobo zisebenzisa ukusebenza vangama lwangaphakathi kakuhle.

- Umthambo-optic yabavavanyi. Le woluvo Fingerprints iyi matrix ifayibha enombala, apho ifayibha nganye iqulathe photocell.

- yabavavanyi Electro-enombala. umfanekiso Ukulungiselela livela Polymer electrooptic nesebenzisa umaleko kukukhanya-esikhupha.

- Optical efakwa scanner. Olu hlobo nezixhobo zomsebenzi izixhobo ukuphuculwa ifayibha apho umfanekiso kuyimfuneko ukuba enze umnwe wenu phesheya komhlaba kwaye silusebenzise.

- roller yabavavanyi. Ukuze ufumane umfanekiso kufuneka ubambe umnwe wakho phezu roller, apho wenza imifanekiso ngomnwe ngeepateni papillary.

- yabavavanyi Non-contact. finger scan lwenziwa ngendlela licwecwe. Ngomnwe lusetyenziswa umngxuma apho ekwezi kwimithombo emininzi, kunye nekhamera eyakhelwe-ngaphakathi 'liphuhlisa umfanekiso umnwe.

yabavavanyi ultrasound

Olu hlobo sixhobo uphosa phezu amaza cuke kwi ngomnwe, kwaye zisekelwe phezu kumgama elilinganisiweyo kwamaza eboniswe kwi misinga kunye neengqameko lwakhiwe umfanekiso. Olu hlobo sixhobo yohlukile ukusuka ngentla bahlola ukuba scanning japan umgangatho ongcono.
