1. anti-interference ndi electromagnetic kugwirizanitsa
1. Tanthauzo la kusokoneza
Kusokoneza kumatanthawuza kusokonezeka komwe kumachitika chifukwa cha phokoso lakunja komanso mafunde opanda pake a electromagnetic pakulandila module ya crystal yamadzi.Ingatanthauzidwenso ngati kusokonezeka komwe kumachitika chifukwa cha mphamvu zosafunikira, kuphatikiza kukhudzidwa kwa zizindikiro zina, kutulutsa kwabodza, phokoso lopanga, ndi zina zotero.
２.Kugwirizana kwa electromagnetic ndi anti-interference
Kumbali imodzi, zida zamagetsi ndi mabwalo amagetsi ndi kusokoneza kwakunja, kumbali inayo, zidzasokoneza dziko lakunja.Choncho, chizindikiro chamagetsi ndi chizindikiro chothandiza ku dera, ndipo maulendo ena amatha kukhala phokoso.
Ukadaulo wotsutsana ndi kusokoneza wamagetsi ndi gawo lofunikira la EMC.EMC imayimira e lectro MAG chinthu netic Compatibility, chomwe chimatanthawuza kuti electromagnetic Compatibility.Kugwirizana kwa electromagnetic ndi ntchito ya zida zamagetsi zomwe zimagwira ntchito zawo pamalo opangira ma elekitirodi popanda kuyambitsa kusokoneza kosalekeza.
Kugwirizana kwa Electromagnetic kuli ndi matanthauzo atatu: 1. Zipangizo zamagetsi zitha kuletsa kusokoneza kwamagetsi akunja.2. Kusokoneza kwa electromagnetic komwe kumapangidwa ndi zida zomwezo kudzakhala kochepa kuposa malire omwe adayikidwa ndipo sikudzakhudza magwiridwe antchito amagetsi ena pamalo omwewo;3. Kugwirizana kwa Electromagnetic kwa chipangizo chilichonse chamagetsi ndikoyezeka.
Zinthu zitatu zotsutsana ndi kusokoneza
Pali zinthu zitatu zopanga kusokoneza kwa ma elekitiroma: gwero la kusokoneza kwa ma elekitiroma, njira yolumikizirana ndi kusokoneza kwa ma elekitiroma, zida zomveka komanso kuzungulira.
1. Magwero osokoneza ma elekitiroleti akuphatikizapo zosokoneza zachilengedwe komanso zosokoneza zopangidwa ndi anthu.
2. Njira zolumikizirana zosokoneza ma elekitiromagineti ndi monga conduction ndi radiation.
(1) kugwirizana kwa conduction: Ndizochitika zosokoneza zomwe phokosolo limayendetsedwa ndikuphatikizidwa kuchokera ku gwero lachisokonezo kupita ku zipangizo zowonongeka ndi dera kudzera mu kugwirizana pakati pa gwero losokoneza ndi zipangizo zomveka.Dera lopatsirana limaphatikizapo ma conductor, zida zoyendetsera zida, magetsi, ma impedance wamba, ndege yapansi, resistors, capacitors, inductors ndi mutual inductors, etc.
(2) Kuphatikizika kwa ma radiation: Chizindikiro chosokoneza chimafalikira pakatikati mwa mawonekedwe a ma radiation a electromagnetic wave, ndipo mphamvu yosokoneza imatulutsidwa m'malo ozungulira molingana ndi lamulo la kufalitsa kwamagetsi.Pali mitundu itatu yodziwika bwino yolumikizira ma radiation: 1. Mafunde a electromagnetic otulutsidwa ndi mlongoti wosokoneza amalandiridwa mwangozi ndi mlongoti wa zida zomvera.2.Malo a electromagnetic space amalumikizidwa motsatana ndi kondakitala, yemwe amatchedwa field-to-line coupling.3.Kuphatikizika kwamphamvu kwa ma sigino amtundu wapakati pakati pa ma conductor awiri ofanana kumatchedwa kulumikizana kwa mzere ndi mzere.
4. Njira yotsutsana ndi kusokoneza zinthu zitatu
amafotokoza dera ndi kuchuluka kwa kusokoneza komwe kukuwonetsedwa mu N, ndiye n angagwiritsidwe ntchito kutanthauzira NG * C / I formula: G monga mphamvu ya gwero la phokoso;C ndi chinthu cholumikizira chomwe gwero la phokoso limatumiza kumalo osokonezeka kudzera mwanjira ina;Ine ndikuchita zotsutsana ndi kusokoneza kwa dera losokonezeka.
G, C, I kutanthauza zinthu zitatu zotsutsana ndi kusokoneza.Zitha kuwoneka kuti kuchuluka kwa kusokoneza kwa dera kumayenderana ndi mphamvu g ya phokoso la phokoso, mofanana ndi coupling factor C, komanso mosiyana ndi ntchito yotsutsana ndi kusokoneza I ya dera losokonezeka.Kuti muchepetse n, mutha kuchita izi:
1. G kukhala ang'ono, ndiko kuti, kukhalapo kwa cholinga cha kusokoneza gwero lamphamvu m'malo kupondereza ang'onoang'ono.
2. C iyenera kukhala yaying'ono, phokoso munjira yopatsirana kuti lichepetse kwambiri.
3. Ndimawonjezera, m'malo osokoneza kuti nditenge njira zotsutsana ndi kusokoneza, kotero kuti mphamvu yotsutsa kusokoneza dera, kapena kupondereza phokoso pamalo osokoneza.
Mapangidwe a anti-interference (EMC) ayenera kuyambira pazifukwa zitatu kuti aletse kusokoneza ndikufikira muyezo wa EMC, ndiko kuti, kuletsa gwero la chisokonezo, kudula njira yamagetsi yolumikizirana komanso kukonza chitetezo chazida zokhudzidwa.
3. Mfundo yofufuza magwero a phokoso,
ziribe kanthu momwe zinthu zilili zovuta, ayenera choyamba kuphunzira njira yopondereza phokoso pagwero la phokoso.Mkhalidwe woyamba ndikupeza gwero losokoneza, chachiwiri ndikusanthula kuthekera kwa kupondereza phokoso ndikutengera njira zofananira.
Zina zosokoneza ndizodziwikiratu, monga mphezi, kutumiza kwa wailesi, gridi yamagetsi pakugwiritsa ntchito zida zamphamvu kwambiri.Gwero losokonezali silingathe kuchitapo kanthu pa gwero la kusokoneza.
Zozungulira zamagetsi zimakhala zovuta kupeza magwero osokoneza.Pezani gwero la kusokoneza ndi: panopa, voteji kusintha kwambiri ndi malo pakompyuta dera kusokoneza gwero.Mwamasamu, madera akulu a DI / dt Ndipo du / DT ndi omwe amasokoneza.
4. Mfundo zopezera njira zofalitsa phokoso
1. Gwero lalikulu la phokoso lophatikizana la inductive nthawi zambiri limakhala la kusintha kwakukulu kwamakono kapena ntchito yaikulu yamakono.
2. Kusiyanasiyana kwa magetsi kumakhala kwakukulu kapena kwakukulu pakugwira ntchito kwamphamvu kwambiri, kawirikawiri gwero lalikulu la capacitive coupling.
3. Phokoso la kuphatikizika wamba kumayambitsanso chifukwa cha kutsika kwa voliyumu pamtundu wamba chifukwa cha kusintha kwakukulu komwe kulipo.
4. Chifukwa cha kusintha kwakukulu pakali pano, chigawo chake cha inductance chifukwa cha zotsatira zake ndizovuta kwambiri.Ngati panopa sikusintha,.Ngakhale mtengo wawo wonse utakhala waukulu kwambiri, sizimayambitsa phokoso lolumikizirana kapena capacitive ndipo zimangowonjezera kutsika kwamagetsi kwanthawi zonse.
Zinthu zitatu zotsutsana ndi kusokoneza
