Asebenza Kanjani Amathegi e-RFid?

Kulesi sikhathi samanje, ukuxhumana okungenantambo sekuthathe indlela esixhumana ngayo yafika ezingeni elisha. Lapho ebona izinzuzo eziningi zokuxhumana okungenantambo, umuntu akakwazi ukuzibamba kodwa uyazibuza ukuthi abantu basinda kanjani ngaphandle kokuxhumana okungenantambo esikhathini esidlule. Ukusetshenziswa kokuhlonza ifrikhwensi yomsakazo kungenye yezindlela ezaziwayo lapho ukuxhumana kuthuthuke ngayo eminyakeni edlule.

Kuyamangaza ukuthi abantu abaningi abakaqondi ukuthi isebenza kanjani noma ukuthi i-RFID ithegi isho ukuthini. Okulandelayo, sizokwethula incazelo yamathegi e-RFID nokuthi isebenza kanjani.

Iyini i-RFID?

I-RFID yitemu elivamile lobuchwepheshe bokuhlonza ifrikhwensi yomsakazo. Iwuhlobo lokuxhumana okungenantambo olusebenzisa i-electrostatic noma i-electromagnetic coupling engxenyeni yefrikhwensi yomsakazo we-electromagnetic spectrum. Inezinzuzo zezinga lokudlulisela okusheshayo, ukulwa nokushayisana, ukufunda ngezinga elikhulu, nokufunda ngesikhathi sokunyakaza.

Ayini amathegi e-RFID?

Ithegi ye-RFID ingumkhiqizo wesekethe ohlanganisiwe, owakhiwa i-chip RFID, i-antenna ne-substrate. Omaka be-RFID bafika ngezindlela eziningi nosayizi. Ezinye zingaba zincane njengohlamvu lwerayisi. Ulwazi olukulawa malebula lungabandakanya imininingwane yomkhiqizo, indawo, nenye idatha ebalulekile.

Asebenza kanjani amathegi e-RFID?

Amasistimu e-RFID asebenzisa izingxenye ezintathu eziyinhloko: ama-transceivers, ama-antenna, nama-transponder. Inhlanganisela ye-transceiver kanye ne-antenna yokuskena ibizwa ngokuthi i-interrogator noma umfundi we-RFID. Kuyaqapheleka, nokho, ukuthi kunezinhlobo ezimbili zabafundi be-RFID: ezimile kanye neselula.

Amathegi e-RFID aqukethe ulwazi olugcinwe nge-elekthronikhi futhi asebenza njengamathegi okuhlonza into. Omaka bahlonza, bahlukanise futhi balandelele amafa athile. Aqukethe ulwazi olwengeziwe namandla edatha kunamabhakhodi. Ngokungafani namabhakhodi, ohlelweni lwe-RFID amathegi amaningi afundwa kanyekanye futhi idatha ifundwa noma ibhalwe kumathegi. Ungakwazi ukuhlukanisa omaka be-RFID ngezindlela ezahlukene ngokusekelwe emandleni, imvamisa, kanye nesici sefomu. Ukuze asebenze, wonke amathegi adinga umthombo wamandla ukuze anike amandla i-chip futhi adlulisele futhi amukele idatha. Ukuthi ithegi iwathola kanjani amandla inquma ukuthi i- passive, i-semi-passive, noma iyasebenza.

Izifundi ze-RFID zingaphatheka noma zinamathiselwe unomphela njengamadivayisi axhumeke kunethiwekhi. Isebenzisa amaza omsakazo ukudlulisa isignali eyenza ithegi ye-RFID isebenze. Uma isicushiwe, ithegi ithumela igagasi ku-antenna, ngaleso sikhathi iguqulwa ibe idatha.

I-transponder ingatholakala kuthegi ye-RFID ngokwayo. Uma ubheka ububanzi bokufundwayo bomaka be-RFID, uzobona ukuthi bayahlukahluka ngokusekelwe ezintweni ezihlukahlukene, okuhlanganisa imvamisa ye-RFID, uhlobo lomfundi, uhlobo lomaka, nokuphazamiseka okuvela endaweni ezungezile. Ukuphazamiseka kungavela futhi kwabanye abafundi be-RFID namathegi. Omaka abanamandla kagesi bangase babe nobubanzi obude bokufunda.

Kungani usebenzisa amathegi e-RFID?

Ukuze uqonde ukuthi ithegi ye-RFID isebenza kanjani, kufanele uqale uqonde izingxenye zayo, okuhlanganisa i-antenna, isekethe ehlanganisiwe (IC), kanye ne-substrate. Kukhona futhi ingxenye yethegi ye-RFID enesibopho sokubhala ngekhodi ulwazi, ebizwa ngokuthi i-RFID inlay.

Kunezinhlobo ezimbili eziyinhloko zamathegi e-RFID, ahluka ngokuya ngomthombo wamandla osetshenzisiwe.

Omaka abasebenzayo be-RFID badinga owabo umthombo wamandla (imvamisa ibhethri) kanye nesidluliseli ukusakaza isiginali kumfundi we-RFID. Bangakwazi ukugcina idatha eningi, babe nebanga elide lokufunda, futhi bayinketho enhle kakhulu yezixazululo ezinembayo ezidinga ukulandelela ngesikhathi sangempela. Ziningi futhi ngokuvamile zibiza kakhulu ngenxa yamabhethri adingekayo. Umamukeli uzwa ukuhanjiswa okungaqondile okuvela kumathegi asebenzayo.

Omaka abasebenzayo be-RFID abanawo umthombo wamandla futhi basebenzisa uthi nesekhethi ehlanganisiwe (IC). Uma i-IC ingaphakathi kwenkundla yomfundi, umfundi ukhipha amaza omsakazo ukuze anike amandla i-IC. Lawa mathegi ngokuvamile anqunyelwe olwazini oluyisisekelo lokuhlonza, kodwa mancane ngosayizi, anempilo ende (iminyaka engu-20+) futhi anezindleko eziphansi.

Ngokungeziwe kumathegi e-RFID angenzi lutho, kukhona namathegi e-RFID angenayo i-semi-passive. Kulawa mathegi, ukuxhumana kunikwa amandla yisifundi se-RFID futhi ibhethri lisetshenziselwa ukuqalisa ukujikeleza.

Abantu abaningi bacabanga ngamathegi ahlakaniphile njengamathegi nje e-RFID. Lawa malebula anomaka we-RFID oshumekwe kulebula yokuzinamathisela enebhakhodi enesici. Laba bomaki bangasetshenziswa ibhakhodi noma abafundi be-RFID. Ngamaphrinta edeskithophu, amalebula ahlakaniphile angaphrintwa ngokufunwa, ikakhulukazi amalebula e-RFID adinga okokusebenza okuthuthuke kakhulu.

Amathegi e-RFID asetshenziselwa ini?

Amathegi e-RFID asetshenziselwa ukukhomba nokulandelela noma iyiphi impahla. Zisiza ukukhulisa ukusebenza kahle njengoba zikwazi ukuskena izinombolo ezinkulu zamalebula ngesikhathi esisodwa noma amalebula angase abe ngaphakathi kwamabhokisi noma afihlwe ukuze angabonwa.

Yiziphi izinzuzo zamathegi e-RFID?

Omaka be-RFID banikeza izinzuzo ezimbalwa ngaphezu komaka bendabuko, okuhlanganisa:

Azidingi ukuthintana okubonakalayo. Ngokungafani namalebula ebhakhodi, adinga ukuthintana okubonakalayo nesithwebuli sebhakhodi, amathegi e-RFID awadingi ukuthintana okubonakalayo nesifundi se-RFID ukuze uskene.

Angaskenwa ngamaqoqo. Amalebula endabuko kufanele askeniwe ngalinye ngalinye, okwandisa isikhathi sokuqoqwa kolwazi. Nokho, amathegi e-RFID angaskenwa kanyekanye, enze inqubo yokufunda isebenze kahle.

Bangakwazi ukubethela imilayezo. Idatha efakwe kuthegi ye-RFID ingabethelwa, ivumele izisebenzi ezigunyaziwe kuphela ukuthi ziyifunde, kunokuvumela noma ubani ukuthi askene ulwazi.

Ziyakwazi ukumelana nezimo zemvelo ezinzima. Ngalo mqondo, amathegi e-RFID angakwazi ukumelana nokubanda, ukushisa, umswakama noma umswakama.

Ziyakwazi ukuphinda zisetshenziswe. Ngokungafani namabhakhodi, angakwazi ukuhlelwa ngemva kokuphrinta, ulwazi oluqukethwe kuma-chips e-RFID lungashintshwa, futhi amathegi e-RFID angasetshenziswa kabusha.

Uma kubhekwa izinzuzo eziningi ezinikezwa omaka be-RFID, abakhiqizi baphendukela kubo kancane kancane futhi balahle amasistimu amabhakhodi amadala.
