1, infraredi-sensor headlampisimiso sokusebenza
Idivayisi eyinhloko yokungeniswa kwe-infrared inzwa ye-infrared ye-pyroelectric yomzimba womuntu.Inzwa ye-infrared ye-Human pyroelectric infrared: umzimba womuntu unezinga lokushisa elingaguquki, ngokuvamile cishe amadigri angu-37, ngakho-ke izokhipha ubude begagasi obuthile obungaba ngu-10UM infrared, i-passive infrared probe iwukubona i-infrared ekhishwa umzimba womuntu cishe ngo-10UM kanye nomsebenzi.Imisebe ye-infrared ekhishwa umzimba womuntu cishe engu-10UM ithuthukiswa yisihlungi selensi yeFresnel futhi igxiliswe kunzwa ye-infrared.
Inzwa ye-infrared ivamise ukusebenzisa i-pyroelectric element, elahlekelwa ibhalansi yokushaja lapho izinga lokushisa lokukhanya kwe-infrared lomzimba womuntu lishintsha, likhipha inkokhiso ngaphandle, futhi umjikelezo olandelayo ungacupha isenzo sokushintsha ngemva kokutholwa nokucubungula.Uma othile engena ebangeni lokuzwa kokushintshwa, inzwa ekhethekile ithola izinguquko ku-spectrum ye-infrared yomzimba womuntu, inkinobho ishintsha ngokuzenzakalelayo emthwalweni, umuntu akashiyi ububanzi bokuzwa, inkinobho izoqhubeka nokuvula;Ngemva kokuba umuntu ehambile noma kungekho senzo endaweni yezinzwa, ukubambezeleka kokushintsha (ISIKHATHI siyalungiseka: imizuzwana engu-5-120) kuvala umthwalo ngokuzenzakalelayo.Infrared induction switch induction Angle 120 degrees, 7-10 metres away, isikhathi esandisiwe singalungiswa.
2. Umgomo wokusebenza weisibani senzwa yokuthinta
Umgomo wesibani senzwa yokuthinta ukuthi ukufakwa kwangaphakathi kwe-electronic touch ic kwakha iluphu yokulawula nge-electrode lapho kuthintwa isibani.
Lapho umzimba womuntu uthinta i-electrode yokuzwa, isignali yokuthinta idluliselwa ekugcineni kokuthinta ngokushaya umshini oqondile ukuze ukhiqize isignali ye-pulse, bese ukuphela kokuzwa kokuthinta kuzothumela isignali ye-trigger pulse ukulawula ukukhanya;Uma uyithinta futhi, isignali yokuthinta izodluliselwa ekugcineni kwenzwa yokuthinta ngokushaya ngamandla okwamanje ukukhiqiza isignali ye-pulse, ngalesi sikhathi isiphetho senzwa yokuthinta izoyeka ukuthumela isignali ye-trigger pulse, lapho i-AC inguziro, ukukhanya. izocishwa ngokwemvelo.Nokho, ngezinye izikhathi ngemva kokuhluleka kwamandla noma ukuntengantenga kwe-voltage nakho kuzoba nokukhanya kwawo, uma ukuzwela kwesignali yokwamukela ukuthinta kuyiphepha elihle kakhulu noma indwangu ingalawulwa.
3, elawulwa ngezwiI-headlamp yokungeniswaisimiso sokusebenza
Umsindo ukhiqizwa ukudlidliza.Amaza omsindo ahamba emoyeni, futhi uma ehlangana nokuqinile, azodlulisela lokhu kudlidliza kokuqinile.Izingxenye ezilawulwa yizwi ziyizinto ezizwela ukushaqeka ezivulwa uma kunomsindo (ukumelana kuba kuncane) futhi kunqanyulwe lapho kungekho msindo (ukumelana kuba kukhulu).Khona-ke ngokwenza ukubambezeleka phakathi kwesifunda kanye ne-chip, isifunda singanwetshwa isikhathi esithile lapho kunomsindo.
4, isimiso sokusebenza sesibani sokungenisa ukukhanya
Imojula yenzwa yokukhanya kuqala ithola ubukhulu bokukhanya bese inquma ukuthi kumele ibekwe eceleni futhi ikhiye imojuli ngayinye yesibani senzwa ye-LED ye-infrared.Kunezimo ezimbili:
Emini noma lapho ukukhanya kunamandla, imojula yokungeniswa kwe-optical ikhiya imojuli yokungeniswa kwe-infrared kanye nemojula yokulibaziseka yokushintsha ngokuya ngenani lokungeniswa.
Ebusuku noma lapho ukukhanya kumnyama, imojula yenzwa yokubona izobeka imojuli yenzwa ye-infrared kanye nemojula yokulibaziseka esimweni sokulinda ngokuya ngevelu yenzwa.
Ngalesi sikhathi, uma umzimba womuntu ungena ebangeni lokungeniswa kwesibani, imodyuli yokungeniswa kwe-infrared izoqala futhi ibone isignali, futhi isignali izokwenza imodyuli yokulibaziseka yokulibaziseka ukuvula isibani sokungeniswa kwe-infrared infrared.Uma umuntu eqhubeka nokunyakaza phakathi kwebanga lakho, ukukhanya kwenzwa yomzimba ye-LED kuzokhanya, lapho umuntu ehamba ibanga lakho, ayikho isignali yenzwa ye-infrared, futhi inkinobho yokulibaziseka ivala ngokuzenzakalelayo ukukhanya kwenzwa ye-LED ngaphakathi kwenani lokusetha isikhathi. .Imojuli ngayinye ibuyela emuva kokubekwe eceleni bese ilinda umjikelezo olandelayo.
