Embonini yesimanje, kwezokwelapha kanye nakweze-elekthronikhi zabathengi, ukulinganisa izinga lokushisa okunembile kubalulekile. Njengobuchwepheshe obuthuthukisiwe bokulinganisa izinga lokushisa obungathintani, inzwa yokushisa ye-IR (infrared) isakazeka ngokushesha futhi ishintsha izindlela zokuqapha izinga lokushisa ezimbonini eziningi ngempendulo yayo esheshayo, ukunemba okuphezulu kanye nokuphepha.
Ngokuqhubeka kwezobuchwepheshe, ubuchwepheshe bokulinganisa izinga lokushisa buhlala busungulwa. Izinzwa zokushisa zokuthintana zendabuko, njenge-thermocouples kanye nama-thermistors, yize zisasebenza ezinhlelweni eziningi, zinemikhawulo ezimweni ezithile, njengokungakwazi ukukala izinga lokushisa lezinto ezihambayo, izinto ezishisayo, noma izinto okunzima ukuzifinyelela. Izinzwa zokushisa ze-IR zinqoba le mikhawulo futhi zivula amathuba amasha ngokuphelele okulinganisa izinga lokushisa.
Umgomo wokusebenza wenzwa yokushisa ye-IR
Inzwa yokushisa ye-IR ilinganisa izinga lokushisa lento ngokuthola imisebe ye-infrared eyikhiphayo. Ngokomthetho kaStefan-Boltzmann, noma iyiphi into enokushisa okungaphezu kwe-zero ngokuphelele izokhipha imisebe ye-infrared. Uhlelo lwe-optical ngaphakathi kwenzwa yokushisa ye-IR luqoqa le misebe ye-infrared bese luyigxilisa kumtholi. Umtholi uguqula imisebe ye-infrared ibe yisignali kagesi, futhi ngemva kokucubungula isignali, ukufundwa kokushisa kokukhipha kokugcina.
Inzuzo enkulu
1. Ukulinganisa okungathintani:
Izinzwa zokushisa ze-IR azidingi ukuthintana ngqo nento elinganiswayo, ngakho-ke zingalinganisa ngokuphephile izinga lokushisa lezinto ezishisayo, ezihambayo, noma okunzima ukuzifinyelela. Lokhu kubaluleke kakhulu ezindaweni ezifana nokukhiqizwa kwezimboni, ukuxilongwa kwezokwelapha kanye nokucubungula ukudla.
2. Impendulo esheshayo nokunemba okuphezulu:
Izinzwa zokushisa ze-IR zisabela ngokushesha ezinguqukweni zokushisa futhi zinikeze ukufundwa kwezinga lokushisa ngesikhathi sangempela. Ukunemba kwayo kokulinganisa ngokuvamile kungafinyelela ku-±1°C noma ngaphezulu, okuhlangabezana nezidingo zezinhlelo zokusebenza eziningi.
3. Ububanzi bokulinganisa:
Inzwa yokushisa ye-IR ingalinganisa izinga lokushisa elibanzi kusukela ku--50°C kuya ku-+3000°C futhi ifanelekela izindawo ezahlukahlukene zokushisa okukhulu.
4. Ukulinganisa kanye nokuthwebula izithombe okunezici eziningi:
Ezinye izinzwa zokushisa ze-IR ezithuthukisiwe zingathatha izilinganiso zamaphuzu amaningi noma zikhiqize izithombe zokusatshalaliswa kwezinga lokushisa, eziwusizo ekuhlaziyweni kwezithombe zokushisa kanye nokuphathwa kokushisa.
Isimo sohlelo lokusebenza
Izinzwa zokushisa ze-IR zisetshenziswa ezinhlobonhlobo zezicelo, okuhlanganisa:
1. Ukukhiqiza kwezimboni:
Isetshenziselwa ukuqapha izinga lokushisa kwezinqubo zokucubungula insimbi, ukushisela, ukusakaza kanye nokwelapha ukushisa ukuqinisekisa ikhwalithi yomkhiqizo kanye nokuphepha kokukhiqiza.
2. Insimu yezokwelapha:
Ukuze kulinganiswe izinga lokushisa elingathintani nabantu, ikakhulukazi ngesikhathi sobhubhane, izinzwa zokushisa ze-IR zisetshenziswa kabanzi ezikhumulweni zezindiza, eziteshini, ezikoleni nasezakhiweni zamahhovisi nakwezinye izindawo zokuhlola izinga lokushisa, ukutholakala ngokushesha kweziguli ezinomkhuhlane.
3. Ukucubungula ukudla:
Isetshenziselwa ukuqapha izinga lokushisa kwemigqa yokukhiqiza ukudla ukuqinisekisa ukuthi izinga lokushisa lokudla ngesikhathi sokucubungula, ukugcinwa kanye nokuthuthwa lihlangabezana nezindinganiso zezempilo.
4. Ukuphathwa Kwezakhiwo Nokusebenza Kwamandla:
Ukuhlaziywa kwezithombe zokushisa kwezakhiwo ukuze kutholakale izindawo zokuvuza kokushisa, kuthuthukiswe ukusetshenziswa kwamandla, futhi kuthuthukiswe ukusebenza kahle kwamandla kwezakhiwo.
5. I-Electronics Yabathengi:
Kuhlanganiswe namafoni ahlakaniphile namadivayisi ahlakaniphile asekhaya ukuze kuqashwe izinga lokushisa elizungezile kanye nokuphathwa kwezinga lokushisa ledivayisi ukuze kuthuthukiswe ulwazi lomsebenzisi.
Umbono wesikhathi esizayo
Ngokuqhubeka kwentuthuko kwezobuchwepheshe, ukusebenza kwezinzwa zokushisa ze-IR kuzothuthukiswa kakhulu, futhi izindleko zizoncishiswa kancane kancane. Esikhathini esizayo, kulindeleke ukuthi isetshenziswe kabanzi emikhakheni eminingi, njengezolimo ezihlakaniphile, izimoto ezingenabashayeli kanye namarobhothi ahlakaniphile. Ngesikhathi esifanayo, ngokuthuthukiswa kwe-Intanethi Yezinto kanye nobuchwepheshe bedatha enkulu, izinzwa zokushisa ze-IR zizohlanganiswa namanye amadivayisi ahlakaniphile ukuze kufezwe ukuqapha nokucubungula izinga lokushisa okuhlakaniphile nokuzenzekelayo.
Ucwaningo lwesigameko:
Ngesikhathi sobhubhane lwe-COVID-19, izinzwa zokushisa ze-IR sezibe ithuluzi elibalulekile lokuhlola izinga lokushisa lomzimba. Izindawo eziningi zomphakathi, njengezikhumulo zezindiza, iziteshi nezikole, zifake izinzwa zokushisa ze-IR ukuze kutholakale izinga lokushisa ngokushesha, zithuthukise ngempumelelo ukusebenza kahle kokuhlola futhi zinciphise ingozi yokutheleleka okuthelelanayo. Isibonelo, isikhumulo sezindiza samazwe ngamazwe sifake izinzwa eziningi zokushisa ze-IR ngesikhathi sobhubhane, ezingabona izinga lokushisa labantu abangaphezu kwe-100 ngomzuzu ngokwesilinganiso, okuthuthukisa kakhulu ukusebenza kahle kokuhlola.
Isiphetho:
Ukuvela kwenzwa yokushisa ye-IR kubonisa ukuthi ubuchwepheshe bokulinganisa izinga lokushisa bungene enkathini entsha. Akugcini nje ngokuthuthukisa ukunemba nokusebenza kahle kokulinganisa izinga lokushisa, kodwa futhi kunikeza ukwesekwa okuqinile kokuqapha izinga lokushisa nokuvikelwa kokuphepha ezimbonini eziningi. Ngokusetshenziswa kwayo kabanzi emikhakheni ehlukahlukene, izinzwa zokushisa ze-IR ngokuqinisekile zizoletha ukulula nokuphepha okwengeziwe ekukhiqizweni nasekuphileni kwabantu.
