Zisebenza Njani Iithegi zeRF?

Kule mihla kunye neminyaka, unxibelelwano olungenazingcingo luthathe indlela esinxibelelana ngayo kwinqanaba elitsha. Ukubona iingenelo ezininzi zonxibelelwano olungenazingcingo, umntu akanakuzibamba kodwa uyazibuza ukuba abantu basinda njani ngaphandle konxibelelwano olungenazingcingo kwixesha elidlulileyo. Ukusetyenziswa kokuchongwa kwamaza kanomathotholo yenye yeendlela ezaziwayo oluthe unxibelelwano lwavela ngayo ekuhambeni kweminyaka.

Okumangalisayo kukuba, abantu abaninzi abakaqondi ukuba isebenza njani okanye intsingiselo yethegi yeRFID. Emva koko, siya kwazisa intsingiselo yeethegi zeRFID kunye nendlela esebenza ngayo.

Yintoni i-RFID?

I-RFID ligama eliqhelekileyo lokuchonga itekhnoloji yerediyo. Luhlobo lonxibelelwano olungenazingcingo olusebenzisa i-electrostatic okanye i-electromagnetic coupling kwicandelo lamaza kanomathotholo kwi-electromagnetic spectrum. Ineenzuzo zesantya sothumelo olukhawulezayo, ukuchasana nokungqubana, ukufundwa okukhulu, kunye nokufunda ngexesha lokunyakaza.

Ziziphi iithegi zeRFID?

Ithegi ye-RFID yimveliso yesekethe edibeneyo, eyenziwe nge-chip RFID, i-eriyali kunye ne-substrate. Iithegi zeRFID ziza kwiimilo ezininzi kunye nobukhulu. Ezinye zisenokuba zincinane njengekhozo lerayisi. Ulwazi olukule mibhalo lungabandakanya iinkcukacha zemveliso, indawo, kunye nezinye iinkcukacha ezibalulekileyo.

Zisebenza njani iithegi zeRFID?

Iinkqubo ze-RFID zisebenzisa amacandelo amathathu aphambili: ii-transceivers, ii-eriyali, kunye nee-transponders. Indibaniselwano ye-eriyali yokuskena kunye ne-eriyali yokuskena ibizwa ngokuba si-interrogator okanye i-RFID reader. Kubalulekile ukuqaphela, nangona kunjalo, ukuba kukho iindidi ezimbini zabafundi be-RFID: abamileyo kunye neselula.

Iithegi ze-RFID ziqulethe ulwazi olugcinwe nge-elektroniki kwaye lusebenza njengeethegi zokuchongwa kwezinto. Iithegi zichonga, zihlele kwaye zilandelele ii-asethi ezithile. Ziqulethe ulwazi oluninzi kunye nomthamo wedatha kuneekhowudi zebhakhowudi. Ngokungafaniyo nebarcodes, kwinkqubo yeRFID iithegi ezininzi zifundwa ngaxeshanye kwaye idatha ifundwa okanye ibhaliwe kwiithegi. Ungahlela iithegi zeRFID ngeendlela ezahlukeneyo ngokusekwe kumandla, frequency, kunye nefom factor. Ukuze isebenze, zonke iithegi zifuna umthombo wamandla ukunika amandla itshiphu kwaye uthumele kwaye ufumane idatha. Indlela i-tag iwafumana ngayo amandla imisela ukuba ngaba isenziwa, isiqingatha sokwenziwa, okanye iyasebenza.

Abafundi be-RFID banokuphathwa okanye badityaniswe ngokusisigxina njengezixhobo eziqhagamshelwe kwinethiwekhi. Isebenzisa amaza erediyo ukuhambisa umqondiso ovula ithegi yeRFID. Nje ukuba isebenze, ithegi ithumela amaza kwi-eriyali, apho iguqulwa ibe yidatha.

I-transponder inokufumaneka kwithegi ye-RFID ngokwayo. Ukuba ujonga kuluhlu olufundwayo lweethegi zeRFID, uya kubona ukuba ziyahluka ngokusekwe kwizinto ezahlukeneyo, kubandakanya iRFID frequency, uhlobo lokufunda, uhlobo lwethegi, kunye nokuphazamiseka kokusingqongileyo. Ukuphazamiseka kunokuvela kwabanye abafundi be-RFID kunye neethegi. Iithegi ezinonikezelo lwamandla anamandla zinokuba noluhlu olude lokufunda.

Kutheni usebenzisa iithegi zeRFID?

Ukuze uqonde indlela i-tag ye-RFID esebenza ngayo, kufuneka uqale uqonde amacandelo ayo, kuquka i-eriyali, isekethe edibeneyo (IC), kunye ne-substrate. Kukwakho nenxalenye yethegi ye-RFID enoxanduva lokufaka ikhowudi yolwazi, ebizwa ngokuba yi-RFID inlay.

Kukho iindidi ezimbini eziphambili zeethegi ze-RFID, ezihluka ngokomthombo wamandla osetyenzisiweyo.

Iithegi ze-RFID ezisebenzayo zifuna umthombo wazo wamandla (ngokuqhelekileyo ibhetri) kunye ne-transmitter ukusasaza umqondiso kumfundi we-RFID. Bangakwazi ukugcina idatha eninzi, babe noluhlu olude lokufunda, kwaye lukhetho oluhle kakhulu lwezisombululo ezichanekileyo ezifuna ukulandelwa kwexesha langempela. Zininzi kwaye zibiza kakhulu ngenxa yeebhetri ezifunekayo. Umamkeli uva ukuhanjiswa kwe-unidirectional ukusuka kwiithegi ezisebenzayo.

Iithegi ze-RFID ezisebenzayo azinamthombo wamandla kwaye zisebenzisa i-eriyali kunye nesekethe edibeneyo (IC). Xa i-IC ingaphakathi kwebala lomfundi, umfundi ukhupha amaza erediyo ukunika amandla i-IC. Ezi thegi zihlala zilinganiselwe kulwazi olusisiseko, kodwa zincinci ngobukhulu, zinobomi obude (iminyaka eyi-20+) kwaye ziphantsi kweendleko.

Ukongeza kwiithegi ze-RFID ezingenzi nto, kukwakho neethegi ze-RFID ezingemi-passive. Kwezi thegi, unxibelelwano lunikwa amandla ngumfundi weRFID kwaye ibhetri isetyenziselwa ukuqhuba ukujikeleza.

Abantu abaninzi bacinga iithegi ezihlakaniphile njengeethegi ze-RFID nje. Ezi lebhile zinethegi ye-RFID efakwe kwileyibhile encamathelayo eneempawu zebhakhowudi. Ezi thegi zinokusetyenziswa yibhakhowudi okanye abafundi beRFID. Ngabashicileli bedesktop, iileyibhile ezikrelekrele zinokuprintwa ngokwemfuno, ngakumbi iileyibhile zeRFID zifuna izixhobo eziphezulu.

Zeziphi iithegi zeRFID ezisetyenziselwa ntoni?

Iithegi zeRFID zisetyenziselwa ukuchonga nokulandelela nayiphi na i-asethi. Banceda ukwandisa ukusebenza kakuhle njengoko bekwazi ukuskena amanani amakhulu eelebhile ngaxeshanye okanye iilebhile ezinokuba ngaphakathi kweebhokisi okanye zifihlwe ekubonweni.

Zeziphi iingenelo zeethegi zeRFID?

Iithegi zeRFID zibonelela ngeenzuzo ezininzi ngaphezulu kweethegi zemveli, kubandakanya:

Abafuni uqhagamshelwano olubonakalayo. Ngokungafaniyo neeleyibhile zebhakhowudi, ezifuna unxibelelwano olubonakalayo kunye neskena sebhakhowudi, iithegi zeRFID azifuni unxibelelwano olubonakalayo kunye nomfundi weRFID ukuskena.

Zinokuskenwa ngokweebhetshi. Iileyibhile zemveli kufuneka ziskenwe nganye nganye, kunyuswe ixesha lokuqokelela ulwazi. Nangona kunjalo, iithegi zeRFID zinokuskenwa ngaxeshanye, zenze inkqubo yokufunda isebenze ngakumbi.

Banokuyifihla imiyalezo. Idatha efakwe kwiikhowudi kwithegi ye-RFID inokuguqulelwa ngokuntsonkothileyo, ivumela kuphela abasebenzi abagunyazisiweyo ukuba bayifunde, kunokuvumela nabani na ukuba askene ulwazi.

Ziyakwazi ukumelana neemeko zokusingqongileyo ezinzima. Ngale ndlela, iithegi zeRFID ziyakwazi ukumelana nokubanda, ubushushu, ukufuma okanye ukufuma.

Ziyasetyenziswa kwakhona. Ngokungafaniyo neebarcodes, ezingenako ukuhlelwa emva kokushicilela, ulwazi oluqulethwe kwiitshiphusi zeRFID lunokutshintshwa, kwaye iithegi zeRFID zingaphinda zisetyenziswe.

Xa kunikwe izibonelelo ezininzi zeethegi zeRFID ezinikezelayo, abavelisi bajikela ngokucothayo kubo kwaye bakhuphe iinkqubo zakudala zebhakhowudi.
