Kungani amasignali ejika enza ukuchofoza?

Wonke umuntu kade akujwayela ukuthi uma kuvulwa amasignali ajikayo emotweni kuzwakale ukucofa. Abaningi bayithatha kalula le nto futhi abacabangi ngisho nokuthi yini ebenza babe emotweni yesimanje, nokuthi bayadingeka yini manje. Ake sibheke umlando kuqala.

Umlando wokuvela kwemisindo ehambisana nokufakwa kwesignali yokujika

Izimpawu zokuphenduka zinesikhathi eside ezimotweni. Ekuqaleni kwemboni yezimoto, ama-levers mechanical asetshenziselwa ukukhombisa ukuphenduka, kodwa ekupheleni kweminyaka engu-30 yekhulu leminyaka elidlule, izimpawu zokujika zikagesi zavela ezimotweni. Futhi ngemva kwamashumi ambalwa eminyaka, yonke imoto yayifakwe lo mshini olula, njengoba ubukhona benkomba yokuqondisa kwakudingeka ngokomthetho.

Yini eyayichofoza kumasignali ejika ngalezo zinsuku? Ukukhanyisa kokukhanya kusikhombisi sokuqondisa kunikezwe ukusebenza kwesiphazamisi samanje se-bimetallic. Lapho ipuleti le-bimetallic ngaphakathi kwesiphazamisi lishisisiwe, lalivala isekethe kagesi kuqala ngomkhawulo owodwa, bese kuthi kwesinye, kube ngalo mzuzu lapho ukuchofoza kwenzeka khona. Kamuva, ama-bimetallic breaker athathelwa indawo yi-impulse relays, nayo eyenza ukuchofoza okuyisici.

Umgomo wokusebenza kwe-relay umi kanje. I-impulse relay iwuzibuthe kagesi. Lapho i-current isetshenziswa kukhoyili ye-electromagnetic, kuvela inkambu kazibuthe, eheha i-armature etholakala ngaphakathi kwesistimu futhi ivule isekethe kagesi. Lapho i-current iphela, insimu yamagnetic iyanyamalala, futhi i-armature ibuyela endaweni yayo ngosizo lwesiphethu. Kungalesi sikhathi sokuvala umjikelezo kagesi lapho kuzwakala khona ukuchofoza okuyisici. Kuze kube yilapho isignali yokujika icishwa, umjikelezo uzophinda, futhi ukuchofoza kuzozwakala esinyathelweni ngasinye.

Yile misindo ehlotshaniswa nokusebenza kwezimpawu zokujika.

Yini echofoza ezimotweni zesimanje

Ezimotweni zanamuhla, azisekho ama-bimetallic breaker kanye ne-impulse relays, kodwa ukuchofoza kusele.

Manje isimiso sokusebenza kwezimpawu zokujika sihluke ngokuphelele. Ikhompyutha esebhodini, kwezinye izimo i-relay, inesibopho sokuvula nokukhanyisa inkomba yokuqondisa, kodwa sekuyisikhathi eside iyeka ukwenza imisindo ngesikhathi sokusebenza. Ukuchofoza okujwayelekile kulingiswa ngokuzenzela futhi kwenziwa kabusha izipikha, futhi akuzwakali nhlobo kumadivayisi. Futhi ezimweni ezingavamile kuphela lapho ungezwa khona umsindo obukhoma ovela ekusakazweni okubekwe ngokuqondile kule njongo ngaphansi kwedeshibhodi.

Eminyakeni yamuva nje, imboni yezimoto iye yadlulela phambili, futhi esikhundleni sokuchofoza okujwayelekile lapho uvula ukujika, ungezwa noma yini kusukela kuma-clacks kuya kuma-croaks.

Eqinisweni, konke lokhu kuchofozwa nomsindo akusadingeki, futhi kunalokho kuwukuhlonipha isiko. Futhi ungakwazi ukususa umsindo kuzilungiselelo noma nanoma yimuphi osebenza ngogesi.

Kungani kukhona ingoma?

Ngaphambi kokwenza umshini, umshayeli uvula inkomba yendlela abese exwayisa ngayo abanye abasebenzisi bomgwaqo ngenhloso yakhe. Uma lo mshayeli ekhohliwe ukucisha isignali yokujika (noma engazange acime ngokuzenzekelayo), wephula imithetho futhi akhohlise abanye ngezenzo zakhe. Ngakho, ukuchofoza isignali yokujika yokusebenza yazisa umshayeli ngesidingo sokuyivala ngesikhathi esifanele futhi kuvimbele isimo esiphuthumayo emgwaqeni.

Uma le misindo iphazamisa othile, ungavele uvule umsakazo kakhulu, futhi ukuchofoza kuzofiphala ngokushesha ngemuva.

Manje sekucacile ukuthi izinkinobho zivela kuphi emotweni uma amasignali ejika evuliwe, isizinda sokwenzeka kwawo kanye nenjongo yesimanje. Sekuyisikhathi eside le misindo ijwayelekile, futhi ukuthi iyoba yinto yesikhathi esidlule noma iyohlala esikhathini esizayo, isikhathi siyosho.
