Ukuqashelwa kwezigxivizo zeminwe, njengobunye bobuchwepheshe bokuhlonza i-biometric, ikakhulukazi kusebenzisa umehluko ekuthunjweni kwesikhumba seminwe yabantu, okungukuthi, ama-ridge nezigodi zokuthungwa.Njengoba iphethini yezigxivizo zeminwe yomuntu ngamunye, izindawo zokunqamuka nezimpambanomgwaqo zihlukile, , futhi zihlala zingashintshile ukuphila kwakho konke, ngakho ukuqashelwa kwezigxivizo zeminwe sekuphenduke ubuchwepheshe obusetshenziswa kakhulu nobuvuthwe kakhulu phakathi kobuchwepheshe obuningi bebhayomethrikhi.Njengamanje, ukuqashelwa kwezigxivizo zeminwe sekusetshenziswe kabanzi ekuphenyweni kobugebengu, ukulwa nobushokobezi, ukuphepha kwezwe, ukulwa nezidakamizwa, ukuphepha komphakathi, njll. futhi futhi kusetshenziswa kabanzi kumaselula, amakhompyutha, ama-ATM, ukulawula ukufinyelela kanye nezinhlelo zewashi nsuku zonke. ukuphila.
Umgomo wokusebenza wokuqashelwa kwezigxivizo zeminwe ngokuyinhloko uhlanganisa imisebenzi emithathu: ukufundwa kwezithombe zezigxivizo zeminwe, izici zokukhipha, nokuqhathanisa izigxivizo zeminwe.Ubuchwepheshe obujwayelekile bokuqaphela izigxivizo zeminwe yizi: optical, capacitive, kanye ne-ultrasonic.
Ukubonwa kwezigxivizo zeminwe ezibonakalayo
Ukuqashelwa kwezigxivizo zeminwe kuwubuchwepheshe bokuqaphela izigxivizo zeminwe ezinomlando omude.Isebenzisa izimiso ze-refraction yokukhanya nokubonisa ukuhlonza izigxivizo zeminwe.I-engeli ye-refraction yokukhanya okukhishiwe emigqeni engalingani ebusweni bezigxivizo zeminwe nokukhanya kokukhanya okubonisiwe kuzohluka, ngaleyo ndlela kuqoqwe ukukhanya okuhlukile nezinga lobumnyama lolwazi lwesithombe ukuze kuqedelwe ukuqoqwa kwezigxivizo zeminwe.
Izifundi zeminwe yokubona zinezidingo eziphezulu zomthombo wokukhanya kanye nokuxhumana phakathi kwezigxivizo zeminwe nenzwa, futhi zidinga ukuthintana kahle kwezigxivizo zeminwe nokuqondanisa.Ngakho-ke, amamojula wezigxivizo zeminwe ezibonakalayo ngokuvamile athatha indawo enkulu futhi anezidingo ezithile zokushisa nomswakama, futhi ukunemba kokuqashelwa Kwawo akulungile kakhulu.Inzuzo yalobu buchwepheshe ukuthi buyizindleko eziphansi futhi bufanele izicelo ezijwayelekile zokuqashelwa kwezigxivizo zeminwe, njengemishini yokuhambela izigxivizo zeminwe.
Ukuqashelwa kwezigxivizo zeminwe ezinamandla
Ukuqaphela izigxivizo zeminwe ezinamandla kuyinkimbinkimbi kakhulu kunokubonwa kwezigxivizo zeminwe ezibonakalayo.Umgomo wayo ukuhlanganisa inzwa yokucindezela, i-capacitive sensing, inzwa eshisayo nezinye izinzwa ku-chip.Uma isigxivizo somunwe sicindezela ngaphezulu kwe-chip, inzwa yangaphakathi ye-capacitive izokwakha isithombe sezigxivizo zeminwe ngokusekelwe emehlukweni wokushaja (noma umehluko wezinga lokushisa) okhiqizwe i-crest yesigxivizo seminwe nomkhombe, okudinga ukuthintana okuhle phakathi kwesigxivizo seminwe nenzwa.
Inzuzo yokusebenzisa ukuqashelwa kweminwe ye-capacitive ukuthi ikhwalithi yesithombe iphezulu, ukuhlanekezela kuncane, futhi isignali ye-elekthronikhi izodlula esikhumbeni esifile ebusweni bomunwe, ngakho-ke ukuqashelwa komzimba ophilayo kungenziwa, okuthuthukisa kakhulu ukuphepha kokuqashelwa kwezigxivizo zeminwe.Kodwa-ke, ukuqashelwa kwezigxivizo zeminwe ezinamandla nakho kunokushiyeka kwakho okungokwemvelo.Izithombe zeminwe enembe kakhulu zidinga izinhlayiya ze-capacitive ezixinene kakhulu, ezizokwandisa kakhulu izindleko.Futhi ngenxa yokuthi ukuqashelwa kwezigxivizo zeminwe ezinamandla kuncike ezigodini nasezigodini zomunwe, uma ubuso bomunwe bungcoliswe ukungcola noma umjuluko, kuzoshintsha ulwazi lokuthungwa ebusweni bomunwe, okuholela ekubonweni okungalungile.
Ukuqashelwa kwezigxivizo zeminwe ze-Ultrasonic
Ukuqashelwa kwezigxivizo zeminwe ze-Ultrasonic ubuchwepheshe obusha obusebenzisa amaza omsindo ukuthola ulwazi lwezigxivizo zeminwe.Inzwa ikhipha ama-ultrasonic pulses, ahlakazekile futhi abonakale lapho ehlangabezana namaphethini wezigxivizo zeminwe.Inzwa ithola isignali ye-ultrasonic ebonisiwe futhi ikhiphe izici zezigxivizo zeminwe ngokuhlaziya izinguquko kusiginali.Izifundi zeminwe ze-Ultrasonic zinezidingo eziphansi zokuxhumana phakathi kwezigxivizo zeminwe nenzwa, ngakho-ke zingasebenza uma kunebanga elithile ukusuka endaweni yezigxivizo zeminwe.Inzuzo yalobu buchwepheshe ukumelana kwayo okukhulu nokungcola nokuklwebheka.Kuyindlela ethembisayo yokuhlonza izigxivizo zeminwe.Kodwa-ke, ukuqashelwa kwezigxivizo zeminwe ze-ultrasonic akunawo amaphutha akho.Izindleko zokuqashelwa kwezigxivizo zeminwe ze-ultrasonic ziphezulu, futhi aziphenduli njengokubonwa kwezigxivizo zeminwe ezibonakalayo ne-capacitive.Futhi ayihambisani kahle namafilimu okuvikela ezinye izinto, azokhawulela ukuqashelwa kwezigxivizo zeminwe ze-ultrasonic.ukunemba.
Kuhlanganiswe ndawonye, ukubonwa kwe-optical, capacitive, kanye ne-ultrasonic kunobuhle nobubi bazo.Ukuqashelwa kwezigxivizo zeminwe ezinamandla njengamanje kusetshenziswa kakhulu, kodwa ukuqashelwa kwezigxivizo zeminwe nge-ultrasonic kunesici esiphezulu sokuphepha.Nakuba ukubonwa kwezigxivizo zeminwe kuyindleko ephansi kakhulu, kunokuvikeleka okubi nokusebenza kokuqashelwa.
I-Shenzhen Handheld-Wireless Technology Co, Ltd inikezela ngezinto eziphathwayo ezimangelengele kanye namathebulethi okwamanje asekela izigxivizo zeminwe ezinamandla, anokusebenziseka okuqinile kwezemvelo kanye nokuphikisana okuphezulu kokulwa nomgunyathi.Zingasetshenziswa kabanzi ekuvikelekeni komphakathi, ukuphathwa kokuphepha komphakathi, ukuphepha, ukuphathwa kokulawula ukufinyelela, njll.
