Izinzwa ze-alamungokuvamile isebenza ngokuthola izinguquko zomzimba ezifana nokunyakaza, ukushintsha kwezinga lokushisa, imisindo, njll. Uma inzwa ithola ushintsho, izothumela isignali kusilawuli, futhi isilawuli sizocubungula isignali ngokuvumelana nemithetho echazwe ngaphambilini, futhi ekugcineni ingakwazi. nikeza i-alamu nge-buzzer, isibonisi noma ezinye izindlela.Ngokungeziwe ekutholweni koshintsho lomzimba, izinzwa ze-alamu nazo zisebenza ngokuthola ukuphazamiseka kumasignali angenantambo, amandla amaza kagesi, nezinye izici.Isibonelo, izinzwa kazibuthe zeminyango engenazintambo zithola ukuthi iminyango namafasitela avaliwe yini ngokuthola ukuphazamiseka kwezimpawu ezingenantambo;Ama-motion detectors e-PIR (pyroelectric) athola ukunyakaza ngokuthola amasiginali womuntu we-pyroelectric.Ngaphezu kwalokho, inzwa ye-alamu ingaphinda isebenzise ubuchwepheshe bezinzwa obuhlukene ukuze isebenze ngokuya ngesimo sohlelo oluthile.Ngokwesibonelo, i-alamu yomlilo ingasebenzisa izinzwa zentuthu;auhlelo lokuphepha ekhayaungasebenzisa izinzwa ze-infrared, njalonjalo.

Umgomo wokusebenza nokusebenza kwezinzwa ze-alamu kubalulekile ekuphepheni nasekuthembekeni kwazo.Ngakho-ke, izinzwa ze-alamu zidinga ukuhlolwa okuqinile kanye nezitifiketi ukuze kuqinisekiswe ukuthi zikwazi ukubona ngokunembile imicimbi echazwe ngaphambilini futhi zikhalise i-alamu.Ngesikhathi esifanayo, izinzwa ze-alamu zidinga ukunakekelwa njalo nokuhlolwa ukuze kuqinisekiswe ukusebenza kwazo okufanele.Isibonelo, izinzwa zentuthu zidinga ukuhlanzwa njalo ukuze kuvinjelwe ama-alamu angamanga ngenxa yokunqwabelana kwentuthu, futhi izitholi ezinyakazayo ze-PIR zidinga ukulinganiswa njalo ukuze kuqinisekiswe ukuthi zingathola ukunyakaza ngokunembile.Ngokuvamile, inzwa ye-alamu iyisisetshenziswa sokuvikela esibaluleke kakhulu esingasisiza sithole futhi sinqande izinsongo ezihlukahlukene zokuphepha kusengaphambili.Ngakho-ke, sidinga ukuyinakekela futhi siyisebenzise ngendlela efanele ukuze siqinisekise ukuthi ingasebenza kahle.
Izinkambu zokusetshenziswa kwezinzwa ze-alamu zibanzi kakhulu futhi zikhula njalo.Angasetshenziswa ezinhlelweni zokuphepha zasekhaya, amasistimu wokwakha ezishintshayo, amasistimu ezishintshayo zezimboni, amasistimu okuphatha izimoto, amasistimu okunakekelwa kwezempilo, nokunye.
Kumasistimu okuvikela ekhaya, izinzwa ze-alamu zingasetshenziswa ukuthola ukuthi iminyango namafasitela avuliwe, ukubona izinto ezihambayo, njll., ukuze kuvikelwe ukuphepha komndeni.
Ekwakheni amasistimu ezishintshayo, izinzwa ze-alamu zingasetshenziswa ukuqapha izinhlelo zokuvikela umlilo, izinhlelo zokuqapha imvelo, njll. ukuvikela ukuphepha kwabasebenzi.
Kuzinhlelo ezishintshayo zezimboni, izinzwa ze-alamu zingasetshenziswa ukuqapha imigqa yokukhiqiza, ukubona ukwehluleka kwemishini, njll., ukuze kuthuthukiswe ukusebenza kahle kokukhiqiza.
Ezinhlelweni zokulawulwa kwethrafikhi, izinzwa ze-alamu zingasetshenziswa ukuqapha izimo zethrafikhi, ukubona izingozi zomgwaqo, njll., ukuze kuqinisekiswe ukuphepha kwethrafikhi.
Kuzinhlelo zokunakekelwa kwezempilo, izinzwa ze-alamu zingasetshenziswa ukuqapha impilo yesiguli, ukuthola ukwehluleka kwemishini yezokwelapha, njll. ukuze kugcinwe iziguli ziphilile.
Ngaphezu kwezinhlelo zokusebenza ezishiwo ngenhla, izinzwa ze-alamu zingasetshenziswa nakweminye imikhakha, njenge:
Ukuqapha Imvelo: Izinzwa ze-alamu zingasetshenziswa ukuqapha izinga lomoya, izinga lamanzi, ukungcoliswa komhlabathi, njll.
Ukuvikelwa Kwezilwane: Izinzwa ze-alamu zingasetshenziswa ukuqapha imizila yokufuduka kwezilwane, ukubona imisebenzi yezilwane, njll.
Ezolimo: Izinzwa ze-alamu zingasetshenziswa ukuqapha umswakama wasepulazini, umswakama wenhlabathi, izinga lokushisa elizungezile, njll.
Ukuphepha komphakathi: Izinzwa ze-alamu zingasetshenziswa ukuqapha ukuhamba kwabantu, imililo, njll. ezindaweni zomphakathi.
Imisebenzi kanye nobubanzi bokusetshenziswa kwezinzwa ze-alamu zikhula njalo, futhi zizoba ingxenye ebalulekile yezinhlelo ezihlakaniphile nezizenzekelayo zesikhathi esizayo.
An inzwa ye-alamungokuvamile iqukethe inzwa ngokwayo, iyunithi yokulawula, i-trigger, idivayisi ye-alamu, njll.
Inzwa ngokwayo iyingxenye eyinhloko yenzwa ye-alamu, eqapha indawo ezungezile futhi ikhiqize idatha.
Iyunithi yokulawula iyisikhungo sokulawula senzwa ye-alamu, esetshenziselwa ukucubungula idatha ekhiqizwe inzwa futhi ihlulele ukuthi i-alamu idinga ukucushwa.
I-trigger iyingxenye yokuphuma kwenzwa ye-alamu, lapho iyunithi yokulawula ihlulela ukuthi i-alamu idinga ukuqaliswa, izothumela isignali kusiqhubi.
Idivayisi ye-alamu iyindlela yokugcina ye-alamu yenzwa ye-alamu, okungaba i-buzzer, ukukhanya, umlayezo wombhalo weselula, ucingo, inethiwekhi, njll.
Isimiso sokusebenza senzwa ye-alamu sithi: inzwa ihlale iqapha indawo ezungezile futhi ikhiqize idatha.Ngokusekelwe kule datha, iyunithi yokulawula iyahlulela ukuthi i-alamu idinga ukucushwa.Lapho i-alamu idinga ukuqaliswa, iyunithi yokulawula ithumela isignali ku-trigger, futhi i-trigger ithumela isignali kudivayisi ye-alamu, ekugcineni ibona umsebenzi we-alamu.
