Teko ea EMI/EMC
Tekanyetso ea Electromagnetic Compatibility (EMC) e hlalosoa ho latela maemo a International Electrotechnical Commission (IEC) e le: sistimi kapa sesebelisoa se ka sebetsa ka mokhoa o tloaelehileng tikolohong ea motlakase moo se leng teng, 'me se ke ke sa kena-kenana le lits'ebetso le lisebelisoa tse ling. EMC e kenyelletsa EMI (electromagnetic interference) le EMS (electromagnetic tolerance).
(1) EMI ke lerata la motlakase le hlahisoang ke mochini ka booona ha o ntse o etsa mesebetsi ea ona, e leng kotsi ho litsamaiso tse ling (joalo ka ho korotla haholo, ho ama boroko ba batho ba o potileng);
(2) EMS e bua ka bokhoni ba mochini hore o se ke oa angoa ke tikoloho e potolohileng motlakase oa motlakase ha o ntse o etsa mesebetsi ea ona.
Hobaneng u nahana ka EMC bakeng sa lihlahisoa tsa elektroniki?
Litaba tsa EMC li amana le ho ts'epahala ha lihlahisoa tsa rona. Moralo oa EMC oa sehlahisoa, o kenyelletsang polokeho ea bophelo, o hloka ho ananeloa haholo.
- Ho fihlella 'maraka le litlhoko tsa taolo ea naha: litšitiso tsa khoebo ea tekheniki;
- Litlhokahalo tsa phihlello bakeng sa liindasteri tse khethehileng: sesole, literene, likoloi le liindasteri tse ling;
- Litlhoko tsa tumellano ea motlakase bakeng sa likarolo le litlhoko tsa ts'ebetso ea EMC bakeng sa sehlahisoa ka bosona;
- Litlhoko tsa ts'epahalo: khokahano e ntle ea motlakase e tiisa ts'epahalo ea lits'ebetso tsa mmaraka mme e hloka ho nahanoa ka maemo a fapaneng a ho sebetsa a feteletseng;
- Lisebelisoa tse ikhethileng, joalo ka ts'ireletso ea tlhaiso-leseling ea EMC: thibelo ea tlhahisoleseling ea seea-le-moea, tšitiso ea linotlolo tsa 433 tsa setso tsa koloi, jj.
Lintlha tse tharo tsa EMC
Bakeng sa mathata a EMC, re ka sebelisa mehlala ea potoloho ho aha mefuta ea mathata a EMC le ho fana ka tharollo. Taba ea pele, a re ke re tsebiseng litlhoko tse tharo tsa EMC: mehloli ea litšitiso, litsela tsa phatlalatso, le mehloli e hlokolosi. Har'a bona, tsela ea tšitiso ke eona e thata ka ho fetisisa ho ahlola. Mehloli ea tšitiso le lisebelisoa tse hlokolosi li ka tsejoa ka boiphihlelo.
Mehloli ea tšitiso ea lihlahisoa tsa elektroniki tikolohong ea electromagnetic e fapane, joalo ka:
(1) Phetiso e se nang mohala (4G, 5G, walkie-talkie): tšitiso ea RS
(2) Lehalima: ho kena-kenana le ho phahama ha matla
(3) 'Mele oa motho: Ho kena-kenana le ESD
(4) Ts'ebetso ea li-switches tsa motlakase: tšitiso ea EFT / CS
(1) Tsamaiso,
(2) Khokahano ea sebaka:
(2-1) Khokahano ea bokhoni:
(2-2) Coupling inductive:
joalo ka li-circuits tsa reset, li-circuits tsa sampole tsa sensor, li-circuits tsa puisano tsa data, li-circuits tsa audio le video, joalo-joalo kaofela li nkuoa e le li-circuits tse hlokolosi.
Mokhoa oa ho sebetsana le tšitiso ea elektronike
EMC e sebelisoa haholo ho rarolla mathata a tšitiso. Mekhoa e ka sehloohong hona joale e kenyelletsa
- Ho itšireletsa
- filthara

Ke lihlahisoa life tse lokelang ho lekoa bakeng sa EMC?
- Lisebelisoa tsa Multimedia: ho kenyelletsa lilaptop, libui, liamplifiers, lik'hamera, jj.
- Lisebelisoa tsa molumo: joalo ka libui, liamplifier, joalo-joalo.
- Lisebelisoa tsa ho amohela liphatlalatso: joalo ka seea-le-moea, joalo-joalo.
- Lisebelisoa tsa ka tlung: joalo ka mechini ea ho hlatsoa, li-air conditioner, lihatsetsi, joalo-joalo.
- Lisebelisoa tsa mabone: joalo ka mabone a tafole, li-tubes tsa neon, joalo-joalo.
- Lisebelisoa tsa theknoloji ea tlhahisoleseling: joalo ka li-microcomputer, likhomphutha tse nkehang, liprinta, jj.
- Lisebelisoa tsa video: joalo ka lik'hamera, lik'hamera, joalo-joalo.
- Lisebelisoa tsa taolo ea mabone a boithabiso: joalo ka li-consoles tsa DMX, jj.
- Lisebelisoa tsa motlakase: joalo ka li-drill tsa motlakase, joalo-joalo.
- Lisebelisoa tsa indasteri le tsa bongaka: joalo ka microscope, lisebelisoa tsa motlakase tsa bongaka, jj.
Ke lihlahisoa life tse lokelang ho lekoa bakeng sa EMC?
Re etsa liteko tsa EMC bakeng sa mefuta eohle ea lihlahisoa, ka hona, u seke oa tsilatsila ho ikopanya le rona ho buisana ka lihlahisoa tsa hau tsa elektroniki.
