Kutheni iMetal itshabalalisa iRFID yokufunda uluhlu - kwaye kutheni "ukuphazamiseka" ligama elingalunganga
Uninzi lweenjineli ezifake i-RFID kwindawo yokugcina iimpahla okanye kumgangatho wemveliso ziye zabetha eludongeni olunye: iithegi ezifundeka ngokugqibeleleyo kwiibhokisi zekhadibhodi zithi cwaka ngokupheleleyo xa zifakwe kwishelufu yentsimbi okanye kwizindlu zezixhobo ze-aluminiyam. Ingqondo yethuku kukubiza oku kuphazamiseka kwentsimbi ye-rfid, kwaye igama libambelele kulo lonke ishishini. Kodwa kwinqanaba loyilo lwe-eriyali, into eyenziwa yintsimbi kwithegi yeRFID ayikokuphazamisana nonomathotholo{2}}kwingqondo yobunjineli. Kukutshintsha okuphindaphindayo okubangelwa kukuba umphezulu oqhubayo ube yinxalenye yesakhiwo se-eriyali. Umahluko ubalulekile kuba utshintsha ukulungiswa.
Umseki wejenali yeRFID uMark Roberti uyizekelise ngokuchanekileyo le nto: ukubeka ithegi yeRFID kwintsimbi kufana nokuchukumisa ihanger yebhatyi yentsimbi kwi-eriyali yerediyo yakho ye-FM. Isikhululo sihla siye kwi-static hayi ngenxa yokuba isibonakaliso esitsha sivele, kodwa ngenxa yokuba i-eriyali ayisalungiswanga kwifrikhwensi echanekileyo (Ijenali yeRFID).
Nje ukuba uqonde ukuba ukungaphumeleli okuphambili kukudityaniswa kunokuphazamiseka kwangaphandle, izisombululo zobunjineli zenza ingqiqo njengezicwangciso zokuzahlula i-eriyali: i-ferrite absorbers, i-ceramic substrates, kunye ne-electromagnetic band gap materials.
Ngokusekwe kwiipateni ezibonwe kumashumi amabini eminyaka yokuvelisa iithegi ze-RFID ezichasene -zesinyithi kunye namakhulukhulu okusasazwa kwabathengi, eli nqaku licalula iindlela ezintathu ezibonakalayo emva kokubonisa umqondiso we-rfid kwintsimbi, lithelekisa izisombululo ezine zobunjineli kunye{1}}nedatha yokusebenza elinganisiweyo, kwaye iquka iipateni ezimbini zokusilela eziphumelela uvavanyo lokuqala lokwamkelwa kunye neenyanga ezingaphezulu kuphela emva koko. Ukuba uyaphononongaanti-ithegi zentsimbi zezixhobo zentsimbi, iiracks zeseva, okanye izixhobo zeshishini, isakhelo sesigqibo kwisiqingatha sesibini sakhiwe kuloo meko yokusetyenziswa.
Iindlela ezintathu ezibulala ukusebenza kweTag kwiMetal Surfaces
Ibinzana elithi "intsimbi ibulala i-RFID" yinto yokwenza lula kakhulu. Izinto ezintathu ezahlukeneyo ezibonakalayo zinoxanduva, kwaye nganye ifuna imilinganiselo yobunjineli eyahlukileyo.
Uluhlu lokufunda lwe-UHF RFID lunokwehla ukusuka kwi-8-10 yeemitha ukuya ngaphantsi kweesentimitha ezili-10 kwipleyiti yentsimbi ecaba.Oko kuthotywa okugqithisileyo kubuyela emva kwimbonakalo yamaza ombane (iatlasRFIDstore). Xa umfundi we-RFID ekhupha amaza erediyo ukuya kwithegi ebekwe phezu kwesinyithi, umphezulu wentsimbi ubuyisela umva umqondiso ngokutshintsha kwesigaba. Ukuba umehluko wesigaba usondela kwi-180℃, isiganeko kunye namaza abonakaliswe ngokuyinxenye okanye arhoxisa ngokupheleleyo omnye komnye, ukudala iindawo ezifileyo apho ithegi ifumana phantse akukho mandla. Okukhona umkhulu kwaye umcaba umphezulu wesinyithi, kokukhona unamandla esi siphumo sophindaphindo. Isinyithi esigobileyo okanye esinemingxuma sidala imbonakalo ebuthathaka, yiyo loo nto iithegi ngamanye amaxesha "zisebenza" kumbhobho wentsimbi kodwa zisilele ngokupheleleyo kwi-chassis yomncedisi osicaba. Lo matshini wodwa ubangela uninzi lokusilela kophazamiseko lwentsimbi ye-uhf rfid kwindawo yokugcina kunye neziko ledatha.
Ukufunxa koMqondiso kususa amandla itshiphu yethegi efunekayo ukuze isebenze.Isinyithi asibonisi nje amandla eRF. Ivelisa imisinga yeeddy xa ibekwe kwindawo etshintshanayo ye-electromagnetic, iguqula amandla eRF abe bubushushu. Kwiithegi ze-RFID ezingasebenziyo ezithembele ngokupheleleyo kumandla avuniweyo ukusuka kumqondiso womfundi, oku kufunxa kunokuthetha ukuba itshiphu ayinakuze ibe namandla. Impembelelo iyahluka kabukhali ngokuphindaphindiweyo: iithegi ze-UHF e- 860-960 MHz isibini esinobundlongondlongo ngemiphezulu eqhubayo, ngelixa iithegi ze-frequency eziphantsi-ze-125 kHz zigqobhoza iindawo zentsimbi ngokusebenzayo ngakumbi kodwa umbingelelo wokufunda uluhlu kunye nokuphuma kwedatha.
Ukukhutshwa kwe-eriyali yeyona ndlela ikhethekileyo kwintsimbi{0}}enxulumene nokusilela.I-eriyali yethegi esemgangathweni ye-RFID yenzelwe ukuphinda ivakale ngamaxesha athile, anje nge-915 MHz kwizicelo zaseMntla Melika ze-UHF. Xa i-eriyali ihleli ngokuthe ngqo kumphezulu wesinyithi, isinyithi sijoyina ngokufanelekileyo ulwakhiwo lwe-eriyali. Ukutshintsha kweresonant frequency, iimpedance changes, kunye netshiphu-ukuya{4}}ugqithiso lwamandla eeriyali luyawa. Ithegi ayizange "igxininiswe" ngumthombo wangaphandle. I-eriyali yayo iye yatshintshwa ngokwasemzimbeni yintsimbi engaphantsi kwayo. Yiyo loo nto i-rfid metal interference kwi-asethi yentsimbi ayinakulungiswa ngokunyusa amandla omfundi: ingxaki ikwithegi, hayi umfundi.
Nantsi ingongoma abaninzi abakhokelayo abayitsibayo: ezi ndlela zintathu azichaphazeli zonke iintsimbi ngendlela efanayo. Iintsimbi ezivuthayo njengentsimbi yekhabhoni zenza ilahleko eyomeleleyo yeeddi yangoku kuneentsimbi ezingezizo{1}ezinjengentsimbi yealuminiyam okanye intsimbi engatyiwayo. Ithegi elungiselelwe intsimbi inokungaqhubi kakuhle kubhedu. Kwaye ijometri ibalulekile njengesixhobo. Ithegi kubuso obusicaba bentsimbi -yentsimbi iziphatha ngendlela eyahlukileyo kwenye ekwisilinda yerhasi egobileyo.
Ukuba umthengisi wakho wethegi akakwazi ukukuxelela ukuba zeziphi iintlobo zesinyithi kunye neejiyometri imveliso yabo eyavavanywa ngokuchasene nayo, yiflegi ebomvu leyo phambi kokuba uzibophelele kumyalelo wesambuku.
