Amakhebula Omsindo Avikelekile E-EMI Yezindawo Zezokwelapha

Izikhungo zezokwelapha zithembele ku-EMI evikelekile ikhebula lomsindo ukuqinisekisa ukudluliswa kwesignali okucacile. Amadivayisi azwelayo ahlala evikelekile ekuphazamisekeni. Izibhedlela eziningi ziyakhetha eyenziwe ngekhebula lomsindo lase-thailand ngokwethembeka. Ukukhetha kahle ikhebula kusekela ukuphepha kwesiguli nokusebenza okunembile kwemishini.

Okuthathwayo Okubalulekile

• Izintambo zomsindo ezivikelwe nge-EMI vikela imishini yezokwelapha ebucayi ekuphazamisekeni, uqinisekise amasignali anembile nokuphepha kwesiguli.
• Izintambo ezingavinjiwe zingabangela umsindo kanye nokungasebenzi kahle emishinini ebalulekile njengezihlinzeki-nhliziyo, kubeke impilo yesiguli engcupheni.
• Ukukhetha izintambo ezisezingeni eliphezulu, ezivikelwe kahle ezihlangabezana nezindinganiso zokuphepha zisiza izibhedlela zigcine izinhlelo zezokwelapha ezithembekile neziphephile.

Ukubaluleka Kwekhebula Lomsindo Elivikelwe I-EMI Ezikhungweni Zezokwelapha

Ukuqonda i-EMI kanye Nemithombo Yayo Ekunakekelweni Kwezempilo

Ukuphazamiseka kwe-electromagnetic, noma i-EMI, kuthinta amasistimu amaningi kagesi ezibhedlela. I-EMI ivela kokubili emithonjeni engenantambo nenezintambo. Ezilungiselelweni zokunakekelwa kwezempilo, imithombo evamile ihlanganisa:

• Amaselula
• Imisakazo ye-Walkie-talkie
• Amanethiwekhi angenantambo
• Abasizi bedijithali yomuntu siqu
• Amadivayisi e-Bluetooth

Wonke amadivaysi kagesi akhipha imisebe ye-electromagnetic. Amaselula avame ukunakwa kakhulu ngenxa yemvamisa namandla awo. Ngisho nemishini engaklanyelwe ukudlulisa amasignali ingakhipha imisebe ye-radiofrequency. Izinkinga eziningi ze-EMI zenzeka lapho ama-transmitter angenawaya esebenza eduze kakhulu nezinto ezibucayi. Izibhedlela manje zenza izinqubomgomo zokulinganisa izidingo zokuxhumana ngomakhalekhukhwini nobungozi be-EMI. Abasebenzi kumele bagcine amadivaysi okuhambisa okungenani imitha eyodwa ukusuka kusukela emishinini yezokwelapha ebalulekile ukunciphisa ukuphazamiseka.

Izingozi Zekhebula Lomsindo Engavinjiwe Yezisetshenziswa Zezokwelapha

Akuvinjiwe ikhebula lomsindo kungadala ubungozi obungathi sína ezindaweni zezokwelapha. I-EMI yethula umsindo kagesi ongafuneki ophazamisa amasistimu kagesi. Lo msindo wehlisa izinga lesignali futhi ungabangela amaphutha kumishini enembayo. Ezibhedlela, izinto ezibucayi zidinga izimpawu ezihlanzekile ukuze zisebenze kahle. I-EMI ingahlanekezela amasiginali omsindo noma ibangele ukuthi okokusebenza kungasebenzi kahle.

Izintambo ezingavinjiwe zingabamba i-EMI kanye nokuphazamiseka kwefrikhwensi yomsakazo, okuholela emsindweni, ekuhlanekeni kwezimpawu, nasekufundeni okungamanga. Amadivayisi afana nama-pacemaker, ama-defibrillator, namamonitha asengozini kakhulu. Izintambo zazo zingasebenza njengezimpondo, okuzenza zibe maningi amathuba okuba zibambe ukuphazamiseka. Lokhu kungase kubangele ukungasebenzi kahle kwedivayisi, ama-alamu angamanga, noma ukusebenza okungalungile kwezinto zokusebenza ezisindisa ukuphila. Ukuvikela okufanelekile kukhebuli yomsindo kusiza ukuvimbela ukushaqeka kukagesi, ukunyuka kwamandla, nokuhluleka kwesekethe. Izintambo ezivikelekile zisebenzisa izinto ezifana ne-aluminium foil noma i-copper braid ukuvimba noma ukuqondisa kabusha i-EMI. Lokhu kuvikela kuqinisekisa ukusebenza okuthembekile kanye nezimpawu ezinembile zamadivayisi ezokwelapha abucayi.

Qaphela: Ikhebuli yomsindo evikelekile igcina ukucaca kwesignali nokusebenza kwedivayisi, ivimbela ukuphazamiseka okungafaka engozini ukunakekelwa kwesiguli.

Ukuphepha Kwesiguli Nokunemba Kokuxilongwa

Ukuphepha kwesiguli kuncike ezintweni zokwelapha ezinembile nezithembekile. I-EMI ingaphazamisa ukuhlonza izithombe namadivayisi okuqapha. Imishini enamandla amakhulu njenge-MRI kanye nezikena ze-CT zikhipha izinkambu ezinamandla kazibuthe kagesi. Lezi zinkambu zingaphazamisana nezisetshenziswa eziseduze. Amanethiwekhi angenantambo nezinye izinto zikagesi zengeza endaweni ephithizelayo kazibuthe kagesi ezibhedlela.

I-EMI ingehlisa isithunzi ukunemba kwemiphumela yokuxilonga. Kungase kubangele ikhwalithi yesithombe ephansi, ama-artifact, noma ngisho nokwehluleka ezingxenyeni ze-elekthronikhi. Lokhu kungaholela ekuxilongweni okungalungile noma ekubambezelekeni kokwelashwa, ikakhulukazi ezimeni eziphuthumayo. Isibonelo, ukungasebenzi kahle kwe-pacemaker okudalwe i-EMI kusuka engutsheni yokufudumala kagesi kuxazululwe kuphela ngemva kokukhishwa kwengubo nokuhlelwa kabusha kwedivayisi. Ukutholwa kusenesikhathi kanye nokuncishiswa kwe-EMI kubalulekile ukuvimbela imiphumela emibi.

Izibhedlela zisebenzisa ukuvikela, ukuhlunga, ukubeka phansi, kanye nokuzihlukanisa ukuze zivikele imishini. Abamukeli bokuhlolwa kwe-EMI basiza ukuqapha ukukhishwa kwekhabhoni nokuqinisekisa ukuthotshelwa kwezindinganiso zokuphepha. Lezi zinyathelo zigcina izithombe zezokwelapha nezokuqapha zinembile futhi ziphephile ezigulini.

Izibhedlela ezitshala imali kukhebula lomsindo elivikelwe yi-EMI zinciphisa ingozi yamaphutha okuxilonga futhi zithuthukise imiphumela yesiguli.

Isebenza Kanjani Ikhebula Lomsindo Elivikelwe I-EMI nokuthi Yini Ongayibheka

Izinhlobo Zokuvikela Kukhebula Yomsindo

Ikhebula lomsindo elivikelwe yi-EMI lisebenzisa izinto ezikhethekile ukuvimba amasiginali kazibuthe kagesi angafuneki. Izinhlobo eziyinhloko zokuvikela zihlanganisa i-foil, i-braided, i-spiral, kanye nokuvikela okuhlangene. Ukuvikela i-foil kugoqa i-conductor ngelendlalelo elincane lensimbi, elinikeza ukumbozwa okugcwele ngokumelene nokuphazamiseka kwe-high-frequency. Isivikelo esilukiwe sisebenzisa i-mesh yethusi elukiwe, enikeza ukuvikeleka okuqinile nokuvumelana nezimo, ikakhulukazi ngokumelene ne-EMI yefrikhwensi ephansi. Ukuvikela okuvunguzayo kunikeza ukuguquguquka nesisindo esincane kodwa amandla amancane. Ukuvikela okuhlanganisiwe kusebenzisa izindlela ezimbili noma ngaphezulu zokuvikela okuphezulu. Ithusi lihlala liyinto evamile kakhulu ngenxa ye-conductivity ephezulu kanye nokumelana nokugqwala. I-NINGBO JINGYI ELECTRONIC Co., LTD. isebenzisa isivikelo sethusi esithuthukisiwe emikhiqizweni yayo yekhebula yomsindo wezokwelapha ukuze kuqinisekiswe ukusebenza okuthembekile ezindaweni eziphezulu ze-EMI.

Izici Eziyinhloko Zekhebuli Yomsindo Evikelekile Yekhwalithi Ephezulu ye-EMI

Ikhebuli yomsindo yekhwalithi ephezulu yokusetshenziswa kwezokwelashwa kufanele ibe nesivikelo esiqinile se-EMI, ukwakhiwa okuhlala isikhathi eside, kanye isisekelo esifanele. Ikhebula kufanele lisebenzise izinto zokuqondisa njenge-foil noma ucingo olulukiweyo ukuze limunce ukuphazamiseka. Ukwakhiwa kwamapheya asontekile kusiza ukunciphisa umsindo. Izindlela ezinhle zokubeka phansi zigcina amasignali ephephile futhi ezinzile. Ukuqina kubalulekile ngoba izindawo zezokwelapha zingaba nzima. Izintambo eziguqukayo zenza ukufaka kube lula, kodwa kusafanele zivikele ku-EMI. I-NINGBO JINGYI ELECTRONIC Co., LTD. iklama izintambo zayo kokubili amandla nokuguquguquka, isekela ukwethembeka kwesikhathi eside ezibhedlela.

Amazinga Okulawula kanye Nokuthotyelwa Kwekhebula Lomsindo Wezokwelapha

Ikhebula elilalelwayo lezokwelapha kufanele lihlangabezane nezindinganiso eziqinile ukuze kuqinisekiswe ukuphepha nokusebenza. E-United States, izintambo kufanele ziphumelele ukuhlolwa kokukhishwa kwe-FCC. EYurophu, kokubili ukukhishwa nokuhlolwa kokugomela kuyadingeka ngaphansi koMyalelo we-EMC. Amazwe ase-Asia afana neChina neSouth Korea nawo adinga ukuphuma nokuhlolwa kokugomela. Ukuhambisana namazinga afana ne-IEC 60601-1-2 kubalulekile kumishini yezokwelapha. Izibhedlela kufanele zikhethe izintambo kubahlinzeki abathembekile abafana ne-NINGBO JINGYI ELECTRONIC Co., LTD., abalandela le mithetho ukuze baqinisekise ukusebenza okuphephile nokusebenza kahle.

• Izintambo zomsindo ezivikelwe yi-EMI zivikela amadivaysi abalulekile njengama-pacemaker nama-ventilators ekuphazamisekeni, asekela ukuphepha kwesiguli nokunakekelwa okuthembekile.
• Izinsiza zosizo zokufakwa nokuqeqeshwa okufanele ukuhlangabezana namazinga okugunyazwa futhi ugweme amaphutha abizayo.

Abaphathi bezindawo kufanele babeke phambili lawa makhebuli ukuze bagcine amazinga aphezulu futhi bavikele izinto ezibucayi.
