Inzwa ye-infrared noma inzwa ye-radar yokukhanya kwe-LED?

Eminyakeni yamuva nje, ngaphansi kwethonya le-inthanethi, ukusetshenziswa kwe-smart home sekuvame kakhulu, futhi isibani sokungeniswa singomunye wemikhiqizo eyodwa ethengiswa kakhulu. Kusihlwa noma ukukhanya kumnyama, futhi othile uyasebenza ebangeni lokungeniswa kwecala, lapho umzimba womuntu ushiya noma umisa umsebenzi ngemva kokulibaziseka, yonke inqubo ngaphandle kokushintsha ngesandla, futhi nganoma isiphi isikhathi ukucisha ukukhanya ukonga kakhulu amandla kanye nokuvikelwa kwemvelo. Izibani zokungeniswa zilula kakhulu izandla zamahhala ngesikhathi esifanayo zingasindisa ugesi, ongakwazi ukuthanda, kodwa kunezinhlobo eziningi zokungeniswa ezimakethe emakethe, ukuthi ungakhetha kanjani? Namuhla, ake sikhulume ngezinzwa zomzimba ezijwayelekile kanye nokuzwa kwerada.

Tumehluko wesimiso sokungeniswa

Ngokusekelwe kumgomo we-Doppler effect, inzwa ye-radar ithuthukisa ngokuzimela umjikelezo wokudlulisa nokwamukela we-antenna ye-planar, ibona ngobuhlakani indawo ezungezile ye-electromagnetic, ilungise ngokuzenzakalelayo isimo sokusebenza, icuphe umsebenzi ngokuhambisa izinto, futhi ikhanyise lapho izinto ezihambayo. faka ububanzi bezinzwa; Lapho into ehambayo ihamba ngemva kokulibaziseka kwamasekhondi angu-20, ukukhanya kuyacishwa noma ukukhanya kukhanyiswe kancane, ukuze kuzuzwe umphumela wokonga amandla ohlakaniphile. Isimiso sezinzwa zomzimba womuntu: i-infrared ye-pyroelectric infrared, umzimba womuntu unokushisa komzimba okungaguquki, ngokuvamile kumiswa ku-32-38 degrees, ngakho-ke izokhipha ubude begagasi obuthile obungaba ngu-10um infrared, i-passive infrared probe iwukubona umzimba womuntu ukuze ukhiphe infrared. nomsebenzi. Imisebe ye-infrared igxile kunzwa ye-infrared ngemva kokuthuthukiswa yisihlungi se-Fishel. Inzwa ye-infrared ivamise ukusebenzisa izakhi ze-pyroelectric, ezilahlekelwa ibhalansi yokushaja lapho izinga lokushisa lemisebe ye-infrared yomzimba womuntu lishintsha, likhulule ukushaja ngaphandle, futhi umjikelezo olandelayo ungacupha isenzo sokushintsha ngemva kokutholwa nokucubungula.

 Tumehluko wokuzwela kokungeniswa

Izici zokuzwa kwerada: (1) ukuzwela okuphezulu kakhulu, ibanga elide, i-engeli ebanzi, ayikho indawo efile. Akuthintwa imvelo, izinga lokushisa, uthuli, njll., futhi ibanga lokungeniswa ngeke lifinyezwe. (2) Kukhona ukungena okuthile, kodwa kulula ukuphazanyiswa udonga, ukuzwela kokuphendula kuyancipha, futhi kubangelwa kalula ukuphazamiseka kwemizimba ehambayo njengezinambuzane ezindizayo. Kuvamile emagaraji angaphansi komhlaba, ezitebhisini, emihubheni yesuphamakethe nakwezinye izindawo zokusebenza, ezilungele ukusetshenziswa nsuku zonke.

Izici zokuzwa komzimba womuntu: (1) ukungena okunamandla, okungahlukaniswa kalula yizithiyo, okungathintwa izinto ezihambayo njengezinambuzane ezindizayo. (2) Isimiso sokungeniswa kwe-infrared ye-pyroelectric sisetshenziselwa ukuqalisa isenzo senzwa ngokuqoqa izinguquko zamandla e-infrared, futhi ibanga lokungeniswa nobubanzi kufushane, okungahle kube lula ekushintsheni kwezinga lokushisa elizungezile. Ukungeniswa kwe-infrared yomuntu akufanelekile kakhulu ukusetshenziswa ezindaweni zokupaka ngenxa yokuzwela kwayo okuphansi kokusabela, kodwa kulungele kakhulu ukukhanyisa kwephasishi, njengamaphasishi, amaphasishi, amagumbi angaphansi, izindawo zokugcina impahla, njll.

 Tuyahluka ngokubukeka

Ukungeniswa kwe-radar kusebenzisa amandla okungeniswa kanye nokushayela kokukodwa, okulula ukukufaka, ukubukeka okulula nokuhle. Inzwa yomzimba womuntu kufanele idalule inzwa yomzimba womuntu eyamukelayo ukuze iqoqe izinguquko zamandla e-infrared emvelweni. Inzwa yangaphandle ye-infrared izothinta ukubukeka nomuzwa, kuzoba nezithunzi ezimnyama lapho ukhanyisa isibani, futhi akulula ukuyifaka.

 Ukukhethwa kwezibani

Isibani sokungeniswa siwuhlobo olusha lomkhiqizo wokukhanyisa ohlakaniphile ongalawula ngokuzenzakalelayo umthombo wokukhanya ngemojula yokungeniswa. Imojula yokungeniswa empeleni iyisekhethi yokulawula ukushintshwa okuzenzakalelayo, kunezinhlobo eziningi, njengokuthi "ukulawula izwi", "trigger", "induction", "ukulawula ukukhanya" nokunye kwesibani "akusebenzi", "ukuphuka kalula" nokunye. ezinye izinkinga, ngokuvamile zicabangele inkimbinkimbi yasekuqaleni - ukwehluleka kwemojula yokungeniswa, kodwa abakhiqizi bokukhanyisa abajwayelekile bamanje banokuhlolwa okuhambisanayo kokuphila, bazoba ezindaweni ezihlukene ukulingisa ukuhluleka, Ukukhetha uphawu oluthembekile kubaluleke kakhulu.I-Lediant Ukukhanyisa kubambe iqhaza ngokujulile embonini yokukhanyisa iminyaka engu-17, futhi bekulokhu kubambelela ekwenzeni izibani ezisezingeni eliphezulu kuphela, ukuze amakhasimende akwazi ukuphumula futhi aneliseke.
