Kev Ntsuas Hluav Taws Xob (EMI)yog lub suab nrov hauv tshuab hluav taws xob uas cuam tshuam nrog teeb liab cable thiab txo qhov kev ncaj ncees ntawm lub teeb liab. EMI feem ntau yog tsim los ntawm kev siv hluav taws xob hauv tshuab hluav taws xob xws li lub zog thiab cov tshuab;
hluav taws xob cuam tshuam yog ib qho hluav taws xob tshwm sim uas tib neeg tau tshawb pom ntev dhau los. Nws yuav luag zoo tib yam li kev siv hluav taws xob. Qhov tshwm sim tau nrhiav tau tib lub sijhawm.
Nyob rau xyoo 1981, cov kws tshawb fawb British tau tshaj tawm tsab xov xwm" Ntawm kev cuam tshuam", uas cim pib ntawm kev tshawb fawb txog kev cuam tshuam. Xyoo 1989, British Hauv Paus Xa Lus thiab Cov Xov Tooj Sib Tham tau cuam tshuam qhov teeb meem cuam tshuam hauv kev sib txuas lus,
thiab cov kev soj ntsuam ntawm cov teeb meem cuam tshuam tau pib tsim thiab kev tsim kho.
Shielding kuj:los ntawm kev pib qhov pib ntxias (eddy tam sim no) tsim hauv tus neeg xyuas pib shielded, lub zog muaj zog crosstalk yog nqus tau.
Lub zog uas tsis nqus yuav tsom tawm rov qab los ntawm tus neeg saib xyuas kev tiv thaiv thiab cov paib kab thiab thaum kawg nqus.
| Kev cuam tshuam hluav taws xob (EMI) | |
| Qhov cuam tshuam los ntawm lub hauv paus | Ntau zaus band |
| VLF cuam tshuam los ntawm cov khoom siv | Hauv qab 30Hz |
| Fais fab zaus thiab cov khoom sib cuam tshuam rau lub suab | 50Hz thiab nws qhov kev sib haum xeeb |
| Tus neeg nqa khoom ntau cuam tshuam cov khoom siv | 10kHz ~ 300kHz |
| Xov tooj cua hauv xov tooj cua thiab yees duab cuam tshuam | 300kHz |
| Microwave cuam tshuam los | 300MHz ~ 100GHz |
Hauv Is Taws Nem, feem ntau muaj teeb meem zoo li no: Lub network cable yuav tsum tau hla cov kav hlau thaum lub sij hawm kho kuv lub tsev. Tom qab lub sijhawm ntev, Kuv pom tias lub network ceev qeeb.
Niaj hnub no, peb tus neeg ua yeeb yam, Lianfu, tau siv ntau tshaj 3 xyoos tshawb nrhiav thiab tsim cov ntaub thaiv tshiab uas haum rau lub zog thiab cov kab taw.
Peb hu nws C-Shield. C-Shield tsis tsuas yog muaj kev tiv thaiv zoo heev tab sis kuj tsis nce tus nqi ntawm cov neeg tsim khoom. Cov ntaub thaiv npog kuj tseem tuaj yeem hloov kho qhov kev tiv thaiv,
uas tsis tsuas yog haum rau kev ua lag luam tam sim no' s tiv thaiv EMI, tab sis kuj tsim nyog rau kev xav tau kev ua lag luam yav tom ntej.
Txhawm rau daws teeb meem EMI ntawm cov khoom, yog tias nws tuaj yeem xav tau thaum pib ntawm cov khoom tsim, nws tuaj yeem txuag nyiaj ntau lub sijhawm thiab tom qab. Txij li cov tswvyim tam sim no ntawm EMI Design-in tsis muaj ntau yam, thiab vim tias qhov kev npaj ua ntej tsis tuaj yeem lav tias cov khoom tiav tuaj yeem ua tiav raws li kev ntsuas hluav taws xob, kev ntsuas cov teeb meem EMI yog qhov tseem ceeb heev rau cov tsim qauv engineers thiab EMI engineers Cov khoom siv no tuaj yeem txo qhov haujlwm ntau rau cov qauv tsim engineers thiab tsim nyog pom zoo.
