Sibutsetelo Izingxenye eziyisisekelo zehardware of Fingerprint Scanner

Ukuze kuvikeleke ngomonakalo owenziwe umuntu kanye nomsebenzi we-electromagnetic kusuka ekuvutheni kwekhoyili ngenxa yokugeleza kwamanje ngenxa yekhoyili ye-electromagnetic ngesizathu esithile, kusetshenziswa ubuchwepheshe bokuqapha kwamanje ekwakhiweni kwesithwebuli zeminwe.

Ukuqapha okuqondayo kanye nokukhiya nge-elekthronikhi kufakwa ezindaweni ezahlukahlukene. Uma umugqa wokuxhumana kanye nomugqa wokuhambisa amandla uhlukaniswa, inani lemizi lekhebula lizokwanda nakanjani, futhi izingozi zokuphepha zizokwanda. Le ndatshana yamukela ubuchwepheshe obuningi obuningi, besebenzisa ikhebula elingama-core kuphela ukufeza ukulethwa kwamandla nokuhanjiswa kolwazi.

Ekupheleni kokudlulisela, ukhiye we-elekthronikhi uqinisa isibonakaliso sedatha elungisiwe ngokusebenzisa i-pulse transformer t bese uyithumela; Ekupheleni kokuthola, i-pulse transformer t igxathuza phansi isinali yedatha etholakele bese uyithumela ku-demodulator ukunciphisa ukulahleka kwesiginali yenethiwekhi ngesikhathi sokudluliselwa. Ukuze sinciphise ukuphazamiseka okuhambisanayo phakathi kokuxhumana nokunikezwa kwamandla, ukukhethwa kwe-choke l kanye ne-copactic capacitor c kufanele kubhekwe ngokuphelele.

Umhleli uzokhala lapha: Isisekelo esiyisisekelo sesithwebuli somunwe empeleni asinankinga enkulu ukusiqonda, futhi ukusebenza kwamazinga okuphepha kuphakeme impela kunalokho kukhiye wendabuko wendabuko, ngakho-ke kuyathandwa kakhulu ngokuthenga kwasekhaya. Lapho ufaka futhi uyisebenzise, ​​ungafisa ukuqhathanisa futhi ubheke umgomo oyisisekelo wokusebenza wesithwebuli somunwe, okuzotholwa nakanjani umphumela wokuthola umzamo!
