Nhanho-ne-Nhanho EMC/EMI Analysis Maitiro
Kuitisa Pre-compliance Testing
Kuziva zvinogona kuitika EMI nyaya kare
Kuongororwa kwekutevedzera mitemo kunobatsira kuona matambudziko eEMI panguva yekutanga kwekugadzirwa kwechigadzirwa. Nzira iyi yekudzivirira kunonoka kunodhura uye inoita kuti chigadzirwa chako chirambe chiri panguva yakatarwa.
Kuziva dhizaini nyaya kutanga mukuita kunogona kudzivirira kunonoka kusingatarisirwe mukutangwa kwechigadzirwa uye kuderedza mitengo ine chekuita nekunonoka-nhanho kuyedzwa. Kwekutanga EMC kuyedzwa kunogonesa kuzivikanwa panguva yekubuda kana kusadzivirirwa nyaya, zvichibvumira shanduko inodiwa yedhizaini pasina kukanganisa hurongwa hwekuvandudza. Pamusoro pezvo, kugadzirisa nyaya dzeEMC kunogona kuwedzera kuita kwechigadzirwa.
Kuti utange, tevera nhanho idzi:
Sarudza iyo inoshanda EMC zviyero zvechigadzirwa chako.
Ita pre-kutevedzera bvunzo kufumura zvinogona kuitika EMI matambudziko.
Sarudza yakaremerwa EMC bvunzo lab yepamutemo certification mushure mekugadzirisa chero nyaya.
Kushandisa nguva-domain uye real-time scanning
Nguva-domain uye chaiyo-nguva yekuongorora matekiniki inobvumidza iwe kuona EMI nekukurumidza uye nemazvo. Real-time scanning inotora zviratidzo zvenguva pfupi izvo nzira dzechinyakare dzinogona kupotsa. Izvi zvinoita kuti utarise zvese zvinogona kukanganisa masosi. Shandisa EMI bvunzo inogamuchira ine chaiyo-nguva yekutarisisa kugona kugadzirisa maitiro uye kugadzirisa huchokwadi.
Kuyera Radiated Emissions
Kumisikidza antenna uye kuisa iyo DUT
Radiated emission bvunzo inoongorora iyo electromagnetic simba rinoburitsa mudziyo wako munzvimbo. Kuti uwane mhedzisiro chaiyo, isa mudziyo uri pasi pekuyedzwa (DUT) pane inotenderera uye siyanisa kureba kweiyo antenna yekugamuchira pakati pe1 kusvika 4 metres. Shandisa semi-anechoic chamber kuti uderedze ruzha rwekumashure uye uve nechokwadi chekuyera kuyerwa.
Kuenzanisa mhedzisiro kumiganhu yekuteerera
Mushure mekuunganidza data, enzanisa kuyerwa kweradiated emissions kune miganhu yekuteerera inotsanangurwa neakakodzera zviyero. Shandisa spectrum analyzer kana EMI test receiver kuongorora zvabuda. Kana iyo inoburitsa yakapfuura miganhu, ungangoda kugadzirisa dhizaini yako kuti uderedze kupindira.
Kuyera Inoitwa Emissions
Kushandisa LISNs yemagetsi tambo yekuyedza
Yakaitwa emission bvunzo inoyera electromagnetic kukanganiswa inofamba netambo dzemagetsi. A Line Impedance Stabilization Network (LISN) inova nechokwadi chekusagadzikana uye kusefa masaini asingadiwe kubva kune magetsi. Izvi zvinokutendera kuti uzvitsaurire uye kuyera kuburitswa kubva kuDUT nemazvo.
Kuongorora kuburitswa kwemafuta achipesana nezviyero
Kana uchinge wapedza zviyero, ongorora zvawanikwa uchienzanisa nemaitiro anoshanda. Kana hutsi hwakaitwa hwakapfuura miganhu inotenderwa, funga kushandisa matekiniki akaita sekudzivirira kana kusefa kurerutsa nyaya. Ongorora zvakare mudziyo kuti uone kuenderana.
Kuita Immunity Testing
Simulating electromagnetic kukanganisa
Kudzivirirwa kwekudzivirira kunoongorora kuti mudziyo wako unoshanda sei kana uchinge wafumurwa nekukanganiswa kwemagetsi. Kutevedzera kukanganisa uku kunosanganisira nzira dzinoverengeka:
EFT (Electrical Fast Transient) : Shandisa EFT/burst generator uye capacitive coupling clamp kuti uise zvinokanganisa mumagetsi kana masaini emagetsi.
Kuedzwa kweKukwira Kwesimba : Tevedzera kukwira kwesimba uchishandisa jenareta yekukwira kwesimba uye zvishandiso zvekubatanidza, uchishandisa zvakananga zvikanganiso kumasaini.
Kuongororwa Kwekudzivirira Kusashanda : Isai common-mode disruptions mumagetsi netambo dzemasaini uchishandisa generator yemasaini nematransducer.
Kudzivirirwa kweRF kwakaitwa : Isa masaini eRF mutambo dzine network dzakatsanangurwa dzekubatanidza.
Kubatanidza Munda Nemwaranzi : Gadzira minda ine maantenna nema waveguides munzvimbo dzakadzivirirwa kuti uderedze kupenya.
Kuyedzwa kweReverberation Chamber : Gadzira munda wakafanana wakakomberedza mudziyo uri kuyedzwa (DUT) nekushandisa mareflection mukamuri rakagadzirirwa.
Idzi nzira dzinoita kuti mudziyo wako ugone kumira chaiwo-epasirese electromagnetic matambudziko pasina kukanganisa kushanda kwayo.
Kuongorora kushanda kwechigadzirwa pasi pekunetseka
Panguva yekuyedzwa kusadzivirirwa, tarisa mashandiro emudziyo wako pasi pekushushikana. Tarisa kune chero kusashanda, kuderedzwa kwekushanda, kana maitiro asingatarisirwi. Semuyenzaniso, tarisa kana mudziyo ukaramba uchishanda zvawaitarisira kana uchinge wasangana nezvinovhiringa. Kana mashandiro acho adonha, tsvaga chikonzero uye shandisa shanduko yekugadzira kuti uvandudze kusimba. Iyi nhanho inovimbisa kuti chigadzirwa chako chinosangana nezvinodiwa zvekuteedzera uye chinoita zvakavimbika munzvimbo yachiri kuda.
Compliance Testing
Kugadzirira kuyedzwa zviri pamutemo kumaLab akabvumidzwa
Kuyedzwa kwekuteerera kunoitwa mumaLab akatenderwa ane maturusi epamberi uye nharaunda dzakadzorwa. Usati waronga bvunzo, ita shuwa kuti mudziyo wako wakanyatso ongorora pre-kutevedzera. Kugadzirira uku kunoderedza njodzi yekukundikana panguva yekuongororwa kwepamutemo. MaLab akatenderwa anotevera maprotocol akasimba kuona kuti mudziyo wako unosangana nezvinodiwa zvekuburitsa uye kusadzivirirwa. Kudyidzana neaya maLab kunovimbisa mibairo chaiyo uye yakatsetseka certification maitiro.
Kuve nechokwadi chezvinyorwa zvizere uye mishumo
Mapepa akakodzera akakosha pakuyedza kutevedzera. Unganidza uye ronga magwaro ese anodiwa pamberi pebvunzo kuti agadzirise maitiro ekuongorora. Vavarira kupedzisa 75-80% yezvinyorwa basa remumunda risati ratanga. Tevedza nhanho idzi kuti uve nechokwadi chezvinyorwa zvakakwana:
Gadzira raibhurari yezvinodiwa kuti utsanangure mazinga ekuteerera anoshanda.
Ita ongororo yekutevedzera njodzi yekuona njodzi dzinogona kuitika.
Gadzira nzira yekuyedza kuti uve nechokwadi chekuongorora kunoshanda.
Pamusoro pezvo, shandisa yakajairwa kushuma fomati kudonongodza zvimiro zvepolicy uye chero shanduko dzakaitwa panguva yekuyedza. Manyoro akakwana haangotsigire kutevedza chete asiwo anorerutsa kuongororwa kweramangwana uye kugadzirisa kwechigadzirwa.
Kududzira Mhedzisiro uye Kugadzirisa Matambudziko eEMI
Kuongorora Test Data
Kuziva mapatani uye anomalies
Kuongorora bvunzo data inhanho yakakosha muEMC/EMI ongororo. Iwe unogona kuona mapatani uye anomalies uchishandisa akati wandei matekiniki:
Nzira dzinoenderana nemitemo : Idzi dzinoshandisa mitemo yakatarwa kare, senge miganho, kuti dzione zvinhu zvisina kujairika zvakajeka.
Matekiniki ekudzidza kwemuchina : Maitiro akadai sekuunganidza zvinhu mumapoka kana miti yesarudzo anobatsira kuwana mapatani akavanzika mumaseti makuru edata.
Kudzidza kwakadzama : Manetwork etsinga anogona kuona mapatani akaomarara asi anoda ruzivo rwakakura rwakanyorwa.
Kuongororwa kwemhando yedata : Kuongorora nguva dzose kunovimbisa kuvimbika kwedata, izvo zvakakosha kuti pave neruzivo rwakarurama.
Nekushandisa nzira idzi, unogona kuona kwainobva kukanganisa uye kugadzira mhinduro dzinoshanda dzekudzigadzirisa.
Kuenzanisa zviwanikwa kune zvikumbaridzo zvekuteerera
Paunenge uchinge waona mapatani, enzanisa mhinduro dzebvunzo kune zvikumbaridzo zvekuteerera zvakatsanangurwa mumiyero yakakodzera. Semuenzaniso, kana zviyero zvako zveEMI zvichidarika zvinobvumidzwa, unofanirwa kuongorora chikonzero. Iyi nhanho inovimbisa kuti mudziyo wako unosangana nezvinodiwa zvekuteedzera uye kudzivirira zvirango zvingangoitika.
Troubleshooting Common EMI Matambudziko
Kuburitsa kwakawandisa kubva kune magetsi
Kuchinja magetsi emagetsi kunowanzo gadzira yakakwira mazinga eEMI. Izvi zvinobuda zvinogona kuguma nekugadzirwa kwakashata kana kusasefa kwakakwana.
