Khetha ukuhlunga kwe-EMI kwamabhodi anezingqimba eziningi ukuze unciphise ukuphazamiseka

Ungayikhetha kanjani imisebe ye-electromagnetic kanye nobuchwepheshe bokuhlunga be-EMI obufanele amabhodi anezingqimba eziningi ukunciphisa ukuphazamiseka kweminye imishini nezinhlelo

Isingeniso:

Njengoba ubunkimbinkimbi bezinto zikagesi buqhubeka bukhula, izinkinga ze-electromagnetic interference (EMI) sezibaluleke kakhulu kunangaphambili. I-EMI ingaba nomthelela omubi ekusebenzeni kwamasistimu kagesi futhi ibangele ukungasebenzi kahle noma ukwehluleka. Ukuxazulula le nkinga, ubuchwepheshe bokuhlunga be-electromagnetic radiation kanye ne-EMI bubalulekile kumabhodi anezinhlaka eziningi. Kulokhu okuthunyelwe kwebhulogi, sizoxoxa ngokuthi ungakhetha kanjani ubuchwepheshe obufanele ukuze unciphise ukuphazamiseka kwamanye amadivayisi namasistimu.

1. Qonda izinhlobo ezahlukene zokugxambukela:

Ngaphambi kokungena enqubweni yokukhetha, kubalulekile ukuba nokuqonda okucacile kwezinhlobo ezahlukene zokuphazamiseka. Izinhlobo ezijwayelekile zifaka i-EMI eyenziwe, i-radiated EMI, kanye ne-EMI yesikhashana. I-EMI eyenziwayo isho umsindo kagesi oqhutshwa ngamandla noma izintambo zesignali. I-EMI esakazwayo, ngakolunye uhlangothi, ingamandla kazibuthe kagesi akhishwa emthonjeni. I-EMI edlulayo ifaka i-voltage engazelelwe noma ama-spikes amanje. Ukunquma uhlobo oluthile lokuphazamiseka obhekene nakho kuzosiza ukunciphisa ubuchwepheshe bokuhlunga obufanele.

2. Nquma ububanzi befrikhwensi:

Imishini kagesi eyehlukene isebenza ngamaza ahlukene. Ngakho-ke, kubalulekile ukunquma ububanzi befrikhwensi lapho ukuphazamiseka okwenzeka khona. Lolu lwazi luzosiza ekukhetheni amasu okuhlunga afanele afana nebanga lokuvama kokuphazanyiswa. Isibonelo, uma ukuphazamiseka kwenzeka kumafrikhwensi aphezulu, isihlungi se-band-pass singase sifaneleke, kuyilapho ukuphazamiseka kwefrikhwensi ephansi kungase kudinge isihlungi se-low-pass.

3. Sebenzisa ubuchwepheshe bokuvikela:

Ngaphezu kobuchwepheshe bokuhlunga, ubuchwepheshe bokuvikela nabo bubalulekile ekunciphiseni ukuphazamiseka. Ukumboza izingxenye ezizwelayo noma amasekhethi ngezinto ezihambisayo kungasiza ukuvimba imisebe ye-electromagnetic. Amathini avikelwe nge-conductively noma ensimbi avame ukusetshenziselwa le njongo. Lapho ukhetha okokuvikela okulungile, cabangela izici ezifana ne-conductivity, ukujiya, kanye nokulula kokuhlanganiswa kumabhodi ezendlalelo eziningi.

4. Funa ubuchwepheshe ekwakhiweni kwebhodi lezingqimba eziningi:

Ukudizayina amabhodi ezendlalelo eziningi anciphisa ukuphazamiseka kudinga ubungcweti bokuhlelwa kanye namasu omzila. Ukusebenza nochwepheshe ogxile ekwakhiweni kwebhodi lezendlalelo eziningi kungasiza ekuhlonzeni izindawo ezingaba nokuphazamiseka kanye nokuthuthukisa isakhiwo ukuze kuncishiswe izinkinga ezinjalo. Ukubekwa kwengxenye efanele, ukucatshangelwa kwendiza yaphansi, kanye nokulawulwa kokuphazamiseka komzila ngezinye zezici ezibalulekile ezifaka isandla ekwakhiweni kwebhodi lezinhlaka eziningi.

5. Hlola futhi uqinisekise:

Uma amasu okuhlunga kanye namasu okuklama esesetshenzisiwe, kubalulekile ukuhlola nokuqinisekisa ukusebenza kwesixazululo esikhethiwe. Ukuhlola kungenziwa kusetshenziswa isamukeli se-EMI kanye nokuhlaziya i-spectrum ukukala inani lokuphazamiseka elikhona. Lesi sinyathelo sizosiza ukuhlonza noma yikuphi ukuthuthukiswa okuqhubekayo okungadingeka futhi kuqinisekiswe ukuthi ubuchwepheshe obukhethiwe empeleni kunciphisa ukuphazamiseka kwamanye amadivaysi namasistimu.

Ngokufigqiwe

Ukukhetha imisebe ye-electromagnetic efanele kanye nezindlela zokuhlunga ze-EMI zamabhodi ezendlalelo eziningi kubalulekile ukuze kuncishiswe ukuphazamiseka kwezinye izinto zokusebenza nezinhlelo. Ukuqonda izinhlobo zokugxambukela, ukunquma ububanzi bemvamisa, ukusebenzisa amasu okuvikela, ukufuna ubuchwepheshe ekwakhiweni kwebhodi lezingqimba eziningi, nokuhlola nokuqinisekisa izixazululo ezikhethiwe zonke izinyathelo ezibalulekile kule nqubo. Ngokulandela le mihlahlandlela, ungaqinisekisa ukusebenza okuphezulu nokuthembeka kwamasistimu akho e-elekthronikhi kuyilapho unciphisa imiphumela emibi yokugxambukela kwe-EMI.
