ukuchongwa kwefrikhwensi ye-dio Itekhnoloji (RFID) itshintshe indlela amashishini alandela kwaye alawula ngayo iiasethi, izinto ezisetyenzisiweyo kunye neekhonkco zokubonelela. Eyona nto iphambili kwinkqubo yeRFID yitshiphu yethegi yeRFID, egcina kwaye idlulise ulwazi ngaphandle kwentambo ngamaza erediyo. Ukukhetha itshiphu efanelekileyo yakho Ileyibhile yeRFID ibalulekile kwinkqubo yokulandelela esebenzayo nephumelelayo. Kweli nqaku, siza kuxoxa ngezinto ezibalulekileyo ekufuneka ziqwalaselwe xa kusenziwa esi sigqibo sibalulekileyo.
1. Iifrequencies kunye neMigangatho
Okokuqala, kufuneka uqwalasele i-frequency yokusebenza kwe-chip ye-RFID tag kunye nemigangatho eyilandelayo. I-frequency eqhelekileyo ibandakanya i-frequency ephantsi (LF), i-frequency ephezulu (HF) kunye ne-frequency ephezulu kakhulu (UHF). I-frequency nganye ineenzuzo zayo ezithile, iingxaki kunye neemeko zokusetyenziswa.
• Iithegi ze-LF RFID: Isantya sokusebenza siphakathi kwe-125 kHz ukuya kwi-135 kHz, umgama wokufunda nokubhala mfutshane, kwaye amandla okungena anamandla. Ingxaki kukuba umthamo wokugcina iithegi umncinci kwaye unokufaneleka kuphela kwizicelo zokuchonga ezikhawulezayo nezifutshane. Xa kuthelekiswa neethegi ze-HF RFID, inani lee-antenna zethegi liphezulu kwaye ixabiso liphezulu. Ukusetyenziswa okuqhelekileyo kolu hlobo lweethegi kubandakanya: ukuchonga izilwanyana, ukuchonga izikhongozeli, ukuchonga izixhobo, ukutshixa nge-elektroniki ukulwa nobusela (izitshixo zemoto ezine-transponder eyakhelwe ngaphakathi), njl.
• Iithegi ze-HF RFID: Isantya sokusebenza esiqhelekileyo: 13.56MHz. Inesantya sokudlulisa idatha esikhawulezayo kwaye ingafunda iithegi ezininzi ngexesha elinye. Kodwa umgama wokufunda nokubhala mfutshane kwaye amandla okungena kwamanzi okanye izinto zesinyithi abuthathaka. Ihlala isetyenziswa kwiimeko ezifana neekhadi ezikrelekrele, ulawulo lwethala leencwadi kunye neenkqubo zokuhlawula.
• Iithegi ze-UHF RFID: iifrikhwensi zokusebenza ezikuluhlu lwe-860 MHz ukuya kwi-960 MHz. Inomgama omde wokufunda nokubhala kunye nokukwazi ukudlulisa idatha ngesantya esiphezulu. Ingxaki kukuba inamandla okungena emanzini okanye kwizinto zesinyithi. Isetyenziswa kakhulu ekulandeleni izinto, kulawulo lwezinto ezisetyenzisiweyo nakwimizi-mveliso yokuthengisa.
Ukongeza, kufuneka uqwalasele umgangatho weRFID osetyenziswayo, njenge-EPC Global, i-ISO 18000, njl. Le migangatho ichaza ubungakanani bethegi, imvamisa, iiprotokholi zonxibelelwano kunye nezinye iimpawu.
2. Amandla okusebenzisa imemori kunye nedatha
Iitships zethegi zeRFID idla ngokuba nobukhulu obahlukeneyo bomthamo wememori, ukusuka kwiibhayithi ezimbalwa ukuya kwiiKB ezininzi. Xa ukhetha itshiphu, kufuneka uqwalasele ubungakanani bememori efunekayo kunye nokukwazi ukugcina idatha kunye nokucubungula. Umthamo wememori omkhulu unokubonelela ngendawo yokugcina idatha kunye namandla okucubungula, kwaye ufanelekile kwiimeko zesicelo ezifuna ukulandelela inani elikhulu lezinto.
3. Ukhuseleko kunye noBucala
Kubaluleke kakhulu ukuqinisekisa ukuba itshiphu yethegi ye-RFID inemisebenzi eyaneleyo yokhuseleko kunye nokhuseleko lwabucala. Cinga ngokukhetha itshiphu exhasa iindlela zokubethela kunye nokulawula ukufikelela ukuze kuthintelwe ukufundwa nokuphazanyiswa okungagunyaziswanga. Ukongeza, ungacinga ngeendlela zokufihla okanye zokuvala ukunciphisa uluhlu olufundekayo lweethegi ukuze ufumane ukhuseleko olongezelelekileyo.
4. Ixabiso kunye nokufumaneka
Xa ukhetha itshiphu ye-RFID tag, kufuneka kuqwalaselwe ixabiso kunye nokufumaneka kwayo. Ixabiso lisoloko liyinto ebalulekileyo kuyo nayiphi na isigqibo sokuthenga. Amaxabiso ayahluka phakathi kweempawu kunye neemodeli zeetshiphu, kwaye kuya kufuneka uzilinganisele ngokusekelwe kuhlahlo-lwabiwo mali lwakho kunye neemfuno zesicelo. Kwangaxeshanye, kubalulekile ukuqinisekisa ukuba itshiphu ekhethiweyo inekhonkco lokubonelela elithembekileyo kwaye kulula ukulidibanisa kwiinkqubo ezikhoyo.
5. Uvavanyo kunye noQinisekiso
Uvavanyo olufanelekileyo kunye nokuqinisekiswa ngamanyathelo abalulekileyo ngaphambi kokukhetha kokugqibela iitships ze-RFID tag. Oku kuquka ukuvavanya ukusebenza kwetships, ukuthembeka kunye nokhuseleko kwiindawo ezahlukeneyo kunye neemeko ukuqinisekisa ukuba iyahlangabezana neemfuno zesicelo sakho. Ukongeza, ungabhekisa kuphononongo kunye namava abanye abasebenzisi ukuze uvavanye ukufaneleka kwetships oyikhethileyo.
6. Ukuqwalasela iimfuno zolwandiso lwexesha elizayo
Njengoko ishishini lakho kunye netekhnoloji yakho zitshintsha, kunokufuneka wandise Inkqubo ye-RFID ukuxhasa imisebenzi engakumbi okanye ukuphatha idatha engaphezulu. Ke ngoko, xa ukhetha itshiphu yethegi yeRFID, nceda uqwalasele iimfuno zokwandiswa kwexesha elizayo kwaye ukhethe imodeli yetshiphu enokukhula. Oku kuya kuqinisekisa ukuba inkqubo inokuziqhelanisa ngokulula notshintsho lwexesha elizayo kunye nokukhula.
Isishwankathelo: Ukukhetha i-chip ye-RFID tag efanelekileyo kufuna ukuqwalaselwa ngokubanzi kwezinto ezininzi, kubandakanya ukuphindaphindwa kunye nemigangatho, amandla okukhumbula kunye nokucubungula idatha, ukhuseleko kunye nobumfihlo, iindleko kunye nokufumaneka, uvavanyo kunye nokuqinisekiswa, kunye neemfuno zokwandiswa kwexesha elizayo. Ngokuvavanya ngononophelo ezi zinto kunye nokwenza izigqibo ezinolwazi ngokusekelwe kwiimfuno zakho zesicelo, uya kukwazi ukukhetha i-chip ye-RFID tag efanelekileyo kwiprojekthi yakho.
