Milkiileyaasha guryaha qaarkood ayaa ogaadey in albaabkooda garaashka ay u soo baxaan sifiican ugama shaqeeyaan si sax ah ka dib markii loo beddelo iftiinka hogaaminaya. Qodobkaani wuxuu sahmi doonaa sababta ay tani u dhacdo iyo sida loo xaliyo dhibaatada iyada oo aan la xallin waxtarka tamarta.
Waa maxay sababta nalalka hogaaminaya ay faragelin ku sameyn karaan furitaanka albaarka albaarka albaarka garaashka?
Rf dhawaq
Qaar ka mid ah nalalka tayada hoose ama kuwa si xun loo gaashaamay Haddii dhawaqa dhawaqyada la soo saaray oo ay la socdaan furitaanka albaabka albaabka garaashka - caadi ahaan 300-400 MHz ama 900 MHz-waxay faragelin ku sameyn kartaa astaan udhaxeysa meel fog iyo furitaanka.
Faragelinta Korantada Korantada
Darawalka gudaha ama awooda korantada ee iftiinka loo yaqaan 'LED' wuxuu abuuri karaa buuq koronto. Marka qaylada ay ku soo noqnoqoto kuwa u dhow kuwa ay isticmaalaan nidaamyada albaab ee garaashka, waxay carqaladeyn kartaa astaan kantaroolka fog, gaar ahaan hadii aan lahayn xakamaynta EMI ee habboon.
Modutch Pulse ballaadhan (PWM)
Nalalka badan ee hogaamiya waxay u isticmaalaan tikniyoolajiyadda PWM si ay u xakameeyaan iftiinka. PWM si dhakhso ah ayey u beddeshaa hogaamiyaha iyo damida, abuurista iswaafajinta sare-soo-soo-gaadhka. Carqaladahan waxay sababi karaan faragelinta soo noqnoqda ee raadiyaha (RFI), kaas oo xannibi kara ama qallooci kara calaamadaha ay heleen albaabka albaabka garaashka.
Calaamadaha caanka ah ee faragelinta
Sideed ku ogaaneysaa in albaabkaaga garaashka uu hogaaminayo faragalin? Halkan waxaa ah qaar ka mid ah calaamadaha caadiga ah ee faragelinta:
- Meesha fog ayaa ka shaqeysa markii aad ugu dhowdahay furitaanka garaashka albaabka garaashka.
- Furitaanka albaabka garaashka ayaa si isdaba joog ah uga jawaabaya. Mararka qaarkood way shaqaysaa, mararka qaarkood ma aha, gaar ahaan marka nalka uu socdo.
- Meel fog kama shaqeyneyso albaabka garaashka gabi ahaanba, laakiin jireedkiisa darbiga ayaa wali shaqeynaya.
- Dhibaatadu waxay dhacdaa ka dib markii lagu beddelo guluubka cusub ee hogaaminaya ama la kulanka.
Sida loo xaliyo ama looga fogaado dhibaatada
Isticmaalayaasha dhamaadka:
● Isticmaal nalalka la xaqiijiyay ee la xaqiijiyey
Waxaad u baahan tahay inaad doorato nalalka hogaamiya ama xayndaabyada lagu xaqiijiyey isugeynta elektaroonigga ah. Alaabada lagu calaamadeeyay FCC Qeybta 15 Fasalka B ama CEC EMC waxay muujinayaan in la tijaabiyay si ay u soo saaraan faragelinta rf ee hooseeya sidaas darteedna ay u badan tahay inay farageliyaan albaabka albaabkaaga albaabkaaga.
● Beddel booska iftiinka
Haddii faragalintu dhacdo, iskuday inaad u dhaqaaqdo booqashada iftiinka ee ka fog furitaanka albaarka albaabka garaashka (ama anteenadiisa la soo qaado). Xitaa dhaqaajinta iftiinka mitir ama laba meel ka baxsan waxay yareyn kartaa faragelinta calaamadaha.
● Ku dar miirayaasha ama anteenada
Xaaladaha ay faragalintu sii socoto, ku darista shaandhaynta RFI iyo anteenooyinka dibadda ayaa laga yaabaa inay gacan ka geystaan xakamaynta saqafka ay ka dhasheen darawalka khafiifka ah iyo hagaajinta soo dhaweynta astaamaha.
Loogu talagalay Soo-saareyaasha Iftiiminta:
● Hagaajinta naqshada Darawalka
Darawalada hogaamiya ayaa ah isha guud ee faragelinta elektaroonigga ah. Si loo yareeyo faragelinta, soosaarayaasha waa inay kujirtaa shaandhaynta EMI ee saxda ah iyo tallaabooyinka samatabbixinta. Adeegsiga qaybo tayo sare leh ayaa sidoo kale ka hortagaya isbeddelada isbeddelka hadda jira, taas oo horseedi karta sanqadha raadiye.
● Tijaabada u hoggaansanaanta EMC
Nalalka hogaamiya waa inay la kulmaan heerarka EMC ee jawiga la degayo si loo hubiyo inaysan soo kicin faragelinta waxyeelada leh ee xaaladaha hawlgalka caadiga ah.Iftiiminta Tri-Cabbirka Tri-CaddiladaWaxaa la meel mariyey imtixaanka EMC oo ku habboon in lagu isticmaalo baarkinka dhulka hoostiisa ah.
● Waxbarashada macaamiisha
Soo-saareyaashu waxay bixin karaan isticmaaleyaasha rakibaadda iyo hagida meelaynta wax soo saarka si loo yareeyo halista faragelinta. Buugaagta rakibaadda fudud ama fiidiyowyada khadka tooska ah waxay yareyn karaan khaladaadka adeegsadaha waxayna wanaajin karaan waxqabadka guud ee barnaamijyada adduunka dhabta ah.
Gabagabo
Luminair tayo hooseeya ayaa u badan inuu faragalin ku sameeyo furitaanka albaarka albaarka albaabka. Haddii aad rabto inaad ka fogaato dhibaatadan, dooro badeecado la xaqiijiyey oo si wanaagsan loo qaabeeyey.
