Iyini isimiso sezibani zokukhanyisa ezisetshenziswa ekufakweni?

1, i-infraredisibani sekhanda senzwaisimiso sokusebenza

Ithuluzi eliyinhloko lokufakwa kwe-infrared yi-pyroelectric infrared sensor yomzimba womuntu. I-pyroelectric infrared sensor yomuntu: umzimba womuntu unezinga lokushisa elingaguquki, ngokuvamile cishe ama-degree angu-37, ngakho-ke izokhipha ubude be-wavelength obuthile obungaba yi-10UM infrared, i-infrared probe engasebenzi iwukuthola i-infrared ekhishwa umzimba womuntu cishe i-10UM bese isebenza. Imisebe ye-infrared ekhishwa umzimba womuntu engaba yi-10UM ithuthukiswa yisihlungi se-Fresnel lens futhi igxile ku-infrared sensor.

Inzwa ye-infrared ivame ukusebenzisa i-pyroelectric element, elahlekelwa ibhalansi yokushaja lapho izinga lokushisa lemisebe ye-infrared yomzimba womuntu lishintsha, ikhipha ishaja ngaphandle, futhi isekethe elandelayo ingabangela isenzo sokushintsha ngemva kokutholwa nokucubungula. Uma umuntu engena ebangeni lokuzwa kokushintsha, inzwa ekhethekile ibona izinguquko ku-spectrum ye-infrared yomzimba womuntu, iswishi ishintsha ngokuzenzakalelayo umthwalo, umuntu akashiyi uhla lokuzwa, iswishi izoqhubeka nokuvula; Ngemva kokuba umuntu ehambile noma kungekho senzo endaweni yokuzwa, ukubambezeleka kokushintsha (ISIKHATHI siyalungiseka: imizuzwana emi-5-120) kuvala umthwalo ngokuzenzakalelayo. I-induction yokushintsha kokushintsha kwe-infrared I-Angle 120 degrees, amamitha angu-7-10 ukusuka lapho, isikhathi eside singalungiswa.

2. Isimiso sokusebenzaisibani sekhanda senzwa yokuthinta

Isimiso sesibani senzwa yokuthinta ukuthi ukufakwa kwangaphakathi kwe-electronic touch ic kwakha iluphu yokulawula ene-electrode lapho kuthintwa isibani.

Uma umzimba womuntu uthinta i-electrode yokuzwa, isignali yokuthinta idluliselwa ekugcineni kokuzwa kokuthinta ngokushaya ugesi oqondile ukuze kukhiqizwe isignali yokushaya, bese ukuphela kokuzwa kokuthinta kuzothumela isignali yokushaya kwe-trigger ukulawula ukukhanya; Uma uyithinta futhi, isignali yokuthinta izodluliselwa ekugcineni kokuzwa kokuthinta ngokushaya ugesi oqondile ukuze kukhiqizwe isignali yokushaya, ngalesi sikhathi ukuphela kokuzwa kokuthinta kuzoyeka ukuthumela isignali yokushaya kwe-trigger, lapho i-AC ingu-zero, ukukhanya kuzocinywa ngokwemvelo. Kodwa-ke, ngezinye izikhathi ngemva kokwehluleka kwamandla noma ukungazinzi kwe-voltage nakho kuzoba nokukhanya kwakho, uma ukuzwela kwesignali yokwamukela kokuthinta kukuhle kakhulu, iphepha noma indwangu nakho kungalawulwa.

3, kulawulwa yizwiisibani sekhanda se-inductionisimiso sokusebenza

Umsindo ukhiqizwa ukudlidliza. Amagagasi omsindo ahamba emoyeni, futhi uma ehlangana ne-solid, azodlulisela lokhu kudlidliza ku-solid. Izingxenye ezilawulwa yizwi ziyizinto ezizwela ukushaqeka ezivulwa uma kunomsindo (ukumelana kuba kuncane) futhi zinqanyulwe uma kungekho msindo (ukumelana kuba kukhulu). Ngemuva kwalokho ngokwenza ukubambezeleka phakathi kwesekethe ne-chip, isekethe ingandiswa isikhathi esithile lapho kunomsindo.

4, isimiso sokusebenza sesibani sokungeniswa kokukhanya

Imojuli yesensa yokukhanya iqala ibone ubukhulu bokukhanya bese inquma ukuthi kufanele ilinde futhi ikhiye imojuli ngayinye yesibani sesensa se-infrared se-LED. Kunezimo ezimbili:

Emini noma lapho ukukhanya kunamandla, i-optical induction module ikhiya i-induction module ye-infrared kanye ne-delay switch module ngokuya ngenani le-induction.

Ebusuku noma lapho ukukhanya kumnyama, i-optical sensor module izobeka i-infrared sensor module kanye ne-delay switch module esimweni sokulinda ngokwenani le-sensor.

Ngalesi sikhathi, uma umzimba womuntu ungena ebangeni lokungeniswa kwesibani, i-infrared induction module izoqala futhi ithole isignali, futhi isignali izoqala i-delay switch module ukuvula isibani sokungeniswa kwe-infrared se-LED. Uma umuntu eqhubeka nokuhamba ngaphakathi kwebanga lakhe, ukukhanya kwenzwa yomzimba we-LED kuzokhanya, lapho umuntu eshiya ibanga lakhe, akukho signali yenzwa ye-infrared, futhi i-delay switch icima ngokuzenzakalelayo ukukhanya kwenzwa ye-infrared ye-LED ngaphakathi kwenani lokusetha isikhathi. I-module ngayinye ibuyela emuva ekulindeni bese ilinda umjikelezo olandelayo.
