Ukushintsha komhlanga ukudluliswa kukagesi okusetshenziswa indawo kazibuthe. Nakuba ingase ibukeke nje njengengcezu yengilazi enomthofu ophuma kuyo, iyithuluzi eliklanywe ngokujulile elisebenza ngezindlela ezimangalisayo ezinezindlela zokwenza ngokwezifiso ezisetshenziselwa ukusetshenziswa kwazo ezinhlelweni eziningi. Cishe wonke amaswishi omhlanga asebenza endaweni yamandla ahehayo: i-polarity ehlukile ikhula endaweni evame ukuvuleka. Lapho i-magnetism yanele, la mandla anqoba ukuqina kwezinsimbi zomhlanga, futhi ukuxhumana kudonsela ndawonye.
Lo mbono waqalwa ngo-1922 nguprofesa waseRussia, u-V. Kovalenkov. Kodwa-ke, ukushintshwa komhlanga kwagunyazwa ngo-1936 ngu-WB Ellwood eBell Telephone Laboratories eMelika. Indawo yokuqala yokukhiqiza ethi "Reed Switches" yafika emakethe ngo-1940 futhi ngasekupheleni kwawo-1950, kwasungulwa ukuhwebelana kwe-quasi-electronic ngesiteshi senkulumo esisekelwe kubuchwepheshe bokushintsha umhlanga kwaqaliswa. Ngo-1963 i-Bell Company yakhipha inguqulo yayo - uhlobo lwe-ESS-1 oluklanyelwe ukushintshaniswa kwe-intercity. Ngo-1977, cishe i-1,000 ukushintshana kwe-elekthronikhi yalolu hlobo kwase kusebenza kulo lonke elase-USA Today, ubuchwepheshe bokushintsha umhlanga busetshenziswa kukho konke kusukela kuzinzwa ze-aeronautical kuya ekukhanyeni kwekhabhinethi okuzenzakalelayo.
Kusukela ekuqashelweni kokulawulwa kwezimboni, kwehle njalo kuya kumakhelwane uMike efuna nje ukukhanya kokuvikela ukuthi kukhanye ebusuku ukuze amtshele uma othile eseduze kakhulu nasekhaya, ziningi izindlela zokusebenzisa lezi zinguquko nezinzwa. Okudingekayo nje inhlansi yobuhlakani bokuqonda ukuthi imisebenzi evamile yansuku zonke ingenziwa kanjani ibe ngcono ngeswishi noma idivayisi yenzwa.
Izici eziyingqayizivele zeswishi yomhlanga zibenza babe yisixazululo esiyingqayizivele senqwaba yezinselele. Ngenxa yokuthi akukho ukugqokwa komshini, isivinini sokusebenza siphezulu futhi ukuqina kuyathuthukiswa. Ukuzwela kwabo okungaba khona kuvumela izinzwa zokushintsha umhlanga ukuthi zishumekwe ngokujulile ngaphakathi kokuhlanganiswa kuyilapho zisasebenza uzibuthe ohlakaniphile. Ayikho i-voltage edingekayo ngoba yenziwe yasebenza ngozibuthe. Ngaphezu kwalokho, izici zokusebenza zokushintshwa komhlanga zizenza zilungele izimo zezulu ezinzima, njengokushaqeka nokudlidliza. Lezi zibaluli zifaka phakathi ukwenziwa kusebenze okungekona othintana naye, abathintwayo abavalwe nge-hermetically, ukujikeleza okulula, kanye nokuthi i-magnetism esebenzayo ihamba phakathi kwezinto ezingezona ayoni. Lezi zinzuzo zenza ukushintsha komhlanga kuphelele ezinhlelweni ezingcolile nezinzima. Lokhu kuhlanganisa ukusetshenziswa kwezinzwa ze-aerospace nezinzwa zezokwelapha ezidinga ubuchwepheshe obuzwela kakhulu.
Ngo-2014, i-HSI Sensing yathuthukisa ubuchwepheshe obusha bokushintsha umhlanga eminyakeni engaphezu kwengu-50: ukushintsha kweqiniso kwefomu B. Akuyona iswishi yefomu C ye-SPDT elungisiwe, futhi ayiyona iswishi ye-SPST echemile ngozibuthe yefomu A. Ngobunjiniyela bamaphethelo, buhlanganisa izindwani zomhlanga eziklanywe ngendlela ehlukile ezithuthukisa ubuhlakani obufana nobukhona bensimu kazibuthe esetshenziswa ngaphandle. Uma amandla kazibuthe enamandla anele amandla axoshayo athuthukiswe endaweni yokuxhumana aphusha amalungu amabili omhlanga aqhelelane, ngaleyo ndlela aphule ukuxhumana. Ngokususwa kwendawo kazibuthe, ukuchema kwabo kwemvelo kubuyisela ukuxhumana okuvamise ukuvaleka. Lena intuthuko yokuqala emisha ngempela kubuchwepheshe bokushintsha umhlanga emashumini eminyaka!
Kuze kube manje, i-HSI Sensing isaqhubeka nokuba ngochwepheshe bemboni ekuxazululeni izinkinga zamakhasimende ekufakeni inselele izinhlelo zokusebenza zokuklama ukushintsha komhlanga. I-HSI Sensing iphinde ihlinzeke ngezixazululo zokukhiqiza ezinembayo kumakhasimende afuna ikhwalithi engashintshi, engenakuqhathaniswa.
