Kooxda RF waxay joojisaa shaandhada

Rf band stocleader techle the tech., Hal-abuurka ugu dambeeya ee tikniyoolajiyadda howsha at-signal - kooxda ayaa joojisay shaandhada (BSF). Miitarkan goynta-goynta ayaa loogu talagalay in si wax ku ool ah loo eego qaybaha soo noqnoqda ee gaarka ah iyadoo loo oggolaanayo inteeda kale ee seenyaalaha si ay ugu gudbaan faragelinta ugu yar.

Band-ka jooji miirayaasha, oo sidoo kale loo yaqaan faashad stors-ka miirayaasha, waa aalado muhiim ah oo ku saabsan elektiroonigga iyo isgaarsiinta. Awooda ay u leedahay xakamaynta soo noqnoqoshada aan la rabin ee kudhawaad ​​nooc cayiman gudaheed ayaa ka dhiga qayb muhiim ah oo ku saabsan codsiyada sida wax ka qabashada maqalka, yareynta fiidiyaha soo noqnoqda, iyo falanqaynta baarlamaanka ee galmada.

Miirayaasheena bandstop waxay bixiyaan saxsanaanta aan kala sooca lahayn iyo waxqabadka, hubinta in kaliya qaybaha xiisaha badan ee danta la xakameeyo inta ay sii wadeen is-dhex-galka guud. Heerkan saxsanaanta ayaa muhiim u ah xaaladaha halka jiritaanka soo noqnoqoshada gaar ah oo hoos u dhajisa tayada calaamadaha ama faragalinta wax soo saarka la doonayo.

Mid ka mid ah faa'iidooyinka ugu waaweyn ee kooxdeena joojiso miirayaasha waa is-weydaarsashadooda. Waxay si aan kala go 'lahayn ugu dhexgali kartaa nidaamyo kala duwan iyo aalado, oo ay ku jiraan qalabka maqalka, shabakadaha isgaarsiinta, iyo aaladaha caafimaadka. Haddii aad ka shaqeyso wax soo saarka maqalka, isgaarsiinta bilaabista ama kormeerka jir ahaaneed, kooxdeena ayaa joojisay miirayaasha inay bixiyaan xalka lagu kalsoonaan karo ee maareynta qaybaha soo noqnoqda ee aan la rabin.

Intaa waxaa sii dheer, shaandhadayada kooxda xabaalaha ah ayaa injineer ah si loo bixiyo wax qabad joogto ah oo la isku halleyn karo, hubinta xasilloonida muddada-dheer iyo cimri dherer. Naqshadeynta adag iyo qaybo tayo sare leh ayaa ka dhigaya inay ku habboon yihiin dalbashada codsiyada warshadaha iyo sidoo kale mashaariicda R & D.

Marka la soo koobi karo, miirayaashayada bandstop-ka ah waxay matalaan horumar ku saabsan tikniyoolajiyadda howsha dil, iyadoo la siinayo hoos u dhac sax ah oo wax ku ool ah oo ah qaybo soo noqnoqda oo gaar ah. Iyada oo is-xakameynteeda iyo isku halaynta, waxay ku habboon tahay xirfadleyda iyo cilmi-baarayaasha doonaya xalka waxqabadka sare ee maareynta faragelinta soo noqnoqda. Khibrad u yeelo farqiga u dhexeeya shaandhayntayada Pardstop-ka oo fur fur Awoodda buuxda ee Codsiyada Diwaanka Digniintaada.
