Ukuba undwendwela umzi-mveliso wale mihla uze ubone izinto ze-elektroniki ezimangalisayo ezisebenza kwi-cell edityanisiweyo, uya kubona iintlobo ngeentlobo zezivamvo ezisemboniselweni. Uninzi lwezi luvo zineengcingo ezahlukeneyo zonikezelo lwamandla ombane, umhlaba kunye nomqondiso. Ukusebenzisa amandla kuvumela inzwa ukuba yenze umsebenzi wayo, nokuba kukujonga ubukho bentsimbi ye-ferromagnetic ekufutshane okanye ukuthumela isibane esikhanyayo njengenxalenye yenkqubo yokhuseleko yeziko. Izitshixo zoomatshini ezithobekileyo ezibangela ezi zivamvo, njengokutshintsha kweengcongolo, zifuna kuphela iingcingo ezimbini ukwenza imisebenzi yazo. Olu tshintsho lusebenza ngokusebenzisa imagnethi.
Yintoni iReed Switch?
Umtshini wengcongolo wazalwa ngo-1936. Yayiyi-brainchild ye-WB Ellwood e-Bell Telephone Laboratories, kwaye yafumana ilungelo layo elilodwa lomenzi ngo-1941. Ukutshintsha kujongeka njenge-capsule yeglasi encinci kunye neentambo zombane eziphuma kwindawo nganye.
Isebenza Njani Utshintsho Lwengcongolo?
Umtshini wokutshintsha uqulathe iincakuba ezimbini zeferromagnetic, zohlulwe ziimicrons ezimbalwa kuphela. Xa umazibuthe usondela kula ncakuba, ezi ncakuba zimbini ziyatsalana. Nje ukubamba, iiblade zivale abafowunelwa abavulwa ngokuqhelekileyo (NO), ukuvumela ukuhamba kombane. Ezinye izitshixo zeengcongolo zikwaqulathe uqhagamshelwano olungelulo lwe-ferromagnetic, olwenza isiphumo esiqhelekileyo esivaliweyo (NC). Umazibuthe osondelayo uya kuqhawula uqhagamshelwano kwaye umke kumfowunelwa otshintshayo.
Uqhagamshelwano lwakhiwe kwiindidi ezahlukeneyo zetsimbi, kuquka i-tungsten kunye ne-rhodium. Ezinye iindidi zide zisebenzisa i-mercury, ekufuneka igcinwe kwindawo efanelekileyo ukuze itshintshe ngokuchanekileyo. Imvulophu yeglasi ezaliswe yigesi engasebenziyo—edla ngokuba yinitrogen—itywina unxibelelwano kuxinzelelo lwangaphakathi phantsi kweatmosfera enye. Ukutywinwa kwahlula abafowunelwa, okuthintela ukubola kunye nazo naziphi na iintlantsi ezinokubakho ngenxa yentshukumo yoqhagamshelwano.
IReed Switch Application kwiLizwe lokwenyani
Uya kufumana izixhobo zoluvo kwizinto zemihla ngemihla ezifana neemoto kunye noomatshini bokuhlamba, kodwa enye yezona ndawo zibalaseleyo ezi zixhobo zisebenza kwii-alam zokuqhekeza. Ngapha koko, ii-alamu sisicelo esiphantse sigqibelele kobu buchwepheshe. Ifestile eshukumayo okanye ucango luhlala umazibuthe, kwaye isivamvo sihlala kwisiseko, sigqithisa umqondiso de kususwe umazibuthe. Xa ifestile ivuliwe—okanye ukuba kukho umntu oqhawula ucingo—kuya kukhala ialam.
Ngelixa ii-alam zokuqhekeza zilusetyenziso olugqwesileyo kukutshintsha kweengcongolo, ezi zixhobo zinokuba zincinci nangakumbi. Ukutshintsha okuncinci kuya kungena ngaphakathi kwezixhobo zonyango ezityisiweyo ezaziwa ngokuba ziiPillCams. Nje ukuba isigulana siginye i-probe encinci, ugqirha unokuyisebenzisa esebenzisa umazibuthe ngaphandle komzimba. Oku kulibaziseka kugcina amandla de iprobe ibekwe ngokuchanekileyo, nto leyo ethetha ukuba iibhetri ezisebhodini zinokuba ncinane nangakumbi, inkalo ebalulekileyo kwinto eyilelwe ukuhamba ngomjelo womntu wokwetyisa. Ngaphandle kobukhulu baso obuncinci, esi sicelo sikwabonisa indlela abanokuba novakalelo ngayo, njengoko ezi zivamvo zinokuchola indawo kazibuthe ngenyama yomntu.
Izitshixo zengcongolo azifuni umazibuthe osisigxina ukuze zisebenze; i-electromagnet relay inokuzivula. Ukusukela oko iBell Labs zaqala ukwenza olu tshintsho, ayimangalisi into yokuba ishishini leefowuni lisebenzise iireyidi zengcongolo kulawulo kunye nemisebenzi yenkumbulo de yonke into yahamba yedijithali ngeminyaka yoo-1990. Olu hlobo lwe-relay alusekho umqolo wenkqubo yethu yonxibelelwano, kodwa zisaxhaphakile kwezinye izicelo ezininzi namhlanje.
Izinto ezilungileyo zeReed Relays
I-sensor yesiphumo seHolo sisixhobo esinobume obuqinileyo esinokubona amasimi amagnetic, kwaye yenye indlela yokutshintsha ingcongolo. Iziphumo zeholo ngokuqinisekileyo zifanelekile kwezinye izicelo, kodwa ukutshintshwa kweengcongolo kubonakalisa ukohlula kombane okungaphezulu kwi-slid-state iqabane labo, kwaye bajongana nokunganyangeki kombane ngenxa yoqhagamshelwano oluvaliweyo. Ukongezelela, ukutshintshwa kweengcongolo kunokusebenza ngeendlela ezahlukeneyo zombane, imithwalo kunye nee-frequencies, njengoko utshintsho lusebenza nje ngocingo oluxhunyiwe okanye olunqanyuliweyo. Kungenjalo, uya kudinga inkxaso yesekethe ukwenza iisenso zeHolo zenze umsebenzi wazo.
Ukutshintsha kweReed kubonisa ukuthembeka okuphezulu ngokumangalisayo kumatshini wokutshintsha, kwaye bayakwazi ukusebenza kwiibhiliyoni zemijikelo ngaphambi kokusilela. Ukongeza, ngenxa yolwakhiwo lwabo olutywiniweyo, banokusebenza kwindawo eqhumayo apho intlantsi inokuba neziphumo ezibi. Ukutshintsha kweengcongolo kusenokuba bubuchwephesha obudala, kodwa kukude nokuba kuphelelwe lixesha. Unokufaka iipakethe eziqulathe iiswitshi zengcongolo kwiibhodi zesekethe eziprintiweyo (PCBs) usebenzisa oomatshini bokuchola kunye nendawo abazenzelayo.
Ulwakhiwo lwakho olulandelayo lunokubiza iintlobo ngeentlobo zeesekethe ezidityanisiweyo kunye nezixhobo, zonke eziye zaqala kwiminyaka embalwa edlulileyo, kodwa ungalibali iswitshi yengcongolo ethobekileyo. Igqibezela umsebenzi wayo osisiseko wokutshintsha ngendlela eqaqambileyo. Emva kweminyaka engama-80 yokusetyenziswa kunye nophuhliso, unokuthembela kuyilo oluzanyiwe lwengcongolo nolwenyani ukuba lusebenze ngokungaguqukiyo.
