Njengoko itekhnoloji iba dibene ngakumbi kubomi bethu bemihla ngemihla, inkxalabo malunga nemitha ye-elektromagnetic (i-EMR) kwizixhobo ze-elektroniki ziyakhula. Ukutshintsha kwenethiwekhi kuyinxalenye ebalulekileyo kwiinethiwekhi zanamhlanje kwaye akukho njalo. Eli nqaku lixoxa ukuba ngaba i-switches ye-Switches ikhrit, amanqanaba e-radiation, kunye nefuthe kubasebenzisi.
Ithini imitha ye-electromagnetic?
Imitha ye-electromagnetic (i-EMR) ibhekisa kumandla ohamba ngendlela ngohlobo lwamaza e-elektromagnetic. La mathungo ayahluka kwi-frequency kwaye abandakanye amaza erediyo, i-microwaves, i-infrared, ukukhanya, i-ultraviolet, i-X-rays, kunye ne-gaymera rays. I-EMR iqhekezwe yimitha ye-ionif (i-radiation yamandla enokubangela umonakalo kwizicubu zebhayiloji, njenge-x-rays) kunye ne-rays engezantsi) kunye neemolekyuli ezingezizo kunye ne-microwave avens).
Ngaba i-switches yenethiwekhi ye-Emitromagnetic?
Inguqulelo yenethiwekhi sisixhobo se-elektroniki esisetyenziselwa ukudibanisa izixhobo ezahlukeneyo kwinethiwekhi yendawo yengingqi (LAN). Njengabaninzi bezixhobo ze-elektroniki, ukutshintsha kwenethiwekhi kwenza inqanaba elithile lemitha ye-electromagnetic. Nangona kunjalo, kubalulekile ukwahlula phakathi kohlobo lwemitha ekhutshiweyo kunye neziphumo zayo zempilo.
1. Uhlobo lwemitha yenethiwekhi
Inqanaba eliphantsi le-ionit: I-switch yenethiwekhi ikakhulu ikhupha imitha yenqanaba le-ionit, kubandakanya ireyithi yerediyo (i-RF) ye-radiation kwaye iphantsi kakhulu kwi-raquation ephantsi. Olu hlobo lomthamo luyafana nalo olukhutshwe zii-elektroniki zasekhaya kwaye alomelelanga ngokwaneleyo kwiiathom ze-iiotime okanye zinomonakalo ngqo wezicubu zebhayiloji.
Ukuphazamiseka kwe-electromagnetic (i-EMI): Ukutshintsha kwenethiwekhi kungakwazi ukuvelisa uphazamiso (i-EMI) ngenxa yemiqondiso yombane abaphathayo. Nangona kunjalo, ukutshintshwa kwenethiwekhi yanamhlanje yenzelwe ukunciphisa i-EMI kwaye ithobele imigangatho yeshishini ukuqinisekisa ukuba azibanga nguphi nakuphazamiseka kakhulu nezinye izixhobo.
I-2. Amanqanaba emisebe kunye nemigangatho
Ihambelana nemigangatho yokhuseleko: Ukutshintsha kwenethiwekhi kuxhomekeke kwimigangatho yolawulo ebekwe yimibutho efana neKhomishini yoNxibelelwano yoNxibelelwano (i-FCC) kunye neKhomishini yeZizwe zeMidlalo ye-Enctrotechnical (IEC). Le migangatho iqinisekisa ukuba izixhobo ze-elektroniki, kubandakanya ukutshintsha kwenethiwekhi, zisebenza ngaphakathi kwemida ekhuselekileyo ye-elektromagnetic radiation kwaye ayizizo iingozi zempilo.
Ukuvezwa kwe-radiation ephantsi: I-switch yenethiwekhi ihlala ikhupha amanqanaba aphantsi kakhulu kwimitha yokufakwa kweminye imithombo yemitha ze-electromagnetic, njengeeselfowuni kunye ne-wi-firs. Imitha yayingalunganga kwimida ekhuselekileyo esekwe zizikhokelo zamazwe.
Iziphumo zeMpilo kunye nokhuseleko
1. Uphando kunye nokufunyanwa
I-radiation ye-ionit: uhlobo lwemitha ekhutshwe yi-switches yenethiwekhi iwela phantsi kodidi lwemitha engekhoyo kwaye ayikhange idityaniswe nemiphumo yempilo ende kuphando lwezempilo kuphando olunzima kuphando olubi. Izifundo ezibanzi kunye nokuphononongwa yimibutho efana noMbutho wezeMpilo weHlabathi (i-WHO) kunye ne-Arhente yamazwe aphesheya komhlaza (iarc) azifumananga ubungqina obuphantsi (i-IARC) azifumananga ubungqina obuphantsi kwinethiwekhi ezibonakalayo zibeka emngciphekweni omkhulu.
Amanyathelo okhuseleko: Ngelixa imvumelwano yangoku yeyokuba imisebe engeyiyo ye-ionit evela kwi-Switch yenethiwekhi ayiyongozi, ihlala inobuqili ukulandela imikhwa yoKhuseleko. Ukuqinisekisa ukungqubana okufanelekileyo kwezixhobo ze-elektroniki, ukugcina umgama ofanelekileyo ukusuka kwizixhobo ze-elektroniki eziphezulu, kwaye emva kwezikhokelo zomenzi kunokunceda ukunciphisa nakuphi na ukuvezwa.
2. Ukubekwa esweni okulawulayo
Iiarhente zolawulo: Iiarhente ezinje nge-FCC kunye ne-IEC zilawula kwaye zibeke iliso kwizixhobo ze-elektroniki ukuqinisekisa ukuba bayayifezekisa imigangatho yokhuseleko. Ukutshintsha kwenethiwekhi kuvavanywa kwaye kuqinisekisiwe ukuqinisekisa ukukhutshwa kwemitha yemitha, kusemda okhuselekileyo, ukukhusela abasebenzisi kwimingcipheko enokubakho.
ukuququmbela
Njengamachaphaza amaninzi e-elektroniki, ukutshintsha kwenethiwekhi kwenza inqanaba elithile lemitha ye-electromagnetic, ngokuyintloko ngohlobo lwemitha esezantsi engaphantsi. Nangona kunjalo, le radiation ixhomekeke kwimida ekhuselekileyo esekwe yimigangatho yolawulo kwaye ayikhange idityaniswe kwiziphumo zempilo ezibi. Abasebenzisi banokusebenzisa inethiwekhi ngokutshintshela njengenxalenye yekhaya labo okanye inethiwekhi yeshishini ngokuzithemba, besazi ukuba izixhobo zenzelwe ukuba zisebenze ngokukhuselekileyo nangokufanelekileyo. ETodanga, sizimisele ukubonelela ngezisombululo ezisemgangathweni zenethiwekhi ezithotyelayo ngemigangatho yokhuseleko, ukuqinisekisa ukusebenza kwengqondo kunye noxolo lwengqondo kubathengi bethu.
