Izindaba

Amathegi e-electronic e-RFID akhiwe ngomaka, abafundi be-rfid kanye nezinhlelo zokugcinwa nokucubungula idatha.Ngokwezindlela ezahlukene zokuphakela amandla, i-RFID ingahlukaniswa ngezinhlobo ezintathu: i-RFID esebenzayo, i-semi-active RFID, ne-passive RFID.Inkumbulo iyichip enothi.Ulwazi oluku-chip lungasetshenziswa ukukhomba okuqondiwe.Umsebenzi oyinhloko ukuhlonza izimpahla.

Umehluko phakathi komaka be-RFID abasebenzayo, abangasebenzi kancane nabangasebenzi kanje:

1. Imiqondo

I-Active rfid inikwa amandla ibhethri elakhelwe ngaphakathi, isigaba samathegi e-elekthronikhi achazwa ngezindlela ezahlukene zokuphakela amandla amathegi e-elekthronikhi, futhi ngokuvamile asekela ukuhlonza amabanga amade.I-RFID esebenzayo i-semi-active umaka okhethekile ohlanganisa izinzuzo zamathegi e-RFID asebenzayo. kanye namathegi e-RFID asebenzayo.Ezimweni eziningi, ngokuvamile ingena esimweni sokungalali futhi ingasebenzi, futhi ayithumeli amasiginali e-RFID emhlabeni ongaphandle.Kuphela uma ingaphakathi kwebanga lesiginali lokuvula le-activator yemvamisa ephezulu, ithegi esebenzayo izovulwa futhi isebenzeI-rfid ye-Passive, okungukuthi, umaka wefrikhwensi yomsakazo we-passive wamukela imodi yokusebenza yenkampani yenethiwekhi, inamandla okumelana nokuphazamiseka, abasebenzisi bangenza ngokwezifiso ukufunda nokubhala idatha ejwayelekile, ukusebenza kahle kulula kakhulu endaweni yesikhulumi esikhethekile, futhi ibanga lokufunda lingafinyelela ngaphezu kwamamitha ayi-10.

2. Isimiso sokusebenza

Ithegi ye-elekthronikhi esebenzayo isho ukuthi amandla omsebenzi wethegi ahlinzekwa yibhethri.Ibhethri, inkumbulo kanye nothi kuhlangene kwakha ithegi ye-elekthronikhi esebenzayo.Ihlukile kuhlobo lokuvula lwefrikhwensi yomsakazo, i-RFID esebenzayo ifakwe isici sokulondoloza esizimele ngaphakathi.Amandla agcwele, futhi usathumela ulwazi ngokusetha ibhendi yefrikhwensi ngaphambi kokuba ibhethri lishintshwe.
Omaka abasebenzayo banebanga elikhudlwana lokusebenza, umthamo omkhulu wesitoreji, namandla ekhompuyutha aqinile ngenxa yokuphakela kwabo amandla okuqhubekayo, futhi bangathumela amasiginali aqukethe ulwazi olusebenzisanayo kumafrikhwensi athile kumfundi.Ukuthembeka kokusebenza kuphezulu, futhi ibanga lokudlulisela isignali lide.Kodwa-ke, ngenxa yethonya lamandla ebhethri, impilo yamathegi asebenzayo inomkhawulo, ngokuvamile kuphela iminyaka engu-3-10.Ngokusetshenziswa kwamandla ebhethri kuthegi, ibanga lokudluliswa kwedatha lizoba lincane futhi libe lincane, okuzothinta ukusebenza okuvamile kwesistimu ye-RFID.

I-semi-active rfid, omaka be-elekthronikhi abavamile abasebenzayo basebenza kubhendi yefrikhwensi engu-433M noma ibhendi yefrikhwensi engu-2.4G.Isebenza kahle ngemuva kokucushwa.Ibanga lokuvula le-activator yefrikhwensi ephezulu lilinganiselwe, futhi alikwazi ukwenziwa lisebenze ngokunembile ebangeni elincane kanye nobubanzi obuncane.Ngale ndlela, umaka osebenzayo ubekwe ne-activator ye-low-frequency njengephoyinti lesisekelo, futhi amaphuzu ayisisekelo ahlukene afakwe ezindaweni ezahlukene, bese kuba enkulu Indawo isebenzisa umfundi webanga elide ukukhomba nokufunda isignali, futhi bese ilayisha isiginali esikhungweni sokuphatha ngezindlela ezihlukene zokulayisha.Ngale ndlela, yonke inqubo yokuqoqwa kwesignali, ukudlulisa, ukucubungula, nokufaka isicelo kuyaqedwa.
Ngokufanayo nethegi esebenzayo, ithegi esebenza kancane nayo inebhethri ngaphakathi, kodwa ibhethri inikeza kuphela usekelo lwesekhethi egcina idatha nesekhethi egcina i-voltage yokusebenza ye-chip, futhi isetshenziselwa ukushayela isekethe ehlanganisiwe. ngaphakathi kwethegi ukugcina isimo sokusebenza.
Ngaphambi kokuthi ithegi ye-elekthronikhi ingene esimweni sokusebenza, ibikade isesimweni sokungalali, esilingana ne-passive tag.Ukusetshenziswa kwamandla kwebhethri ngaphakathi kwethegi kuncane kakhulu, ngakho ibhethri lingahlala iminyaka eminingana noma ngisho neminyaka eyi-10.Lapho ithegi ye-elekthronikhi ingena endaweni yokusebenza yomfundi, ishukunyiswa isignali yefrikhwensi yomsakazo ethunyelwe ngumfundi, futhi umaki ungena esimweni sokusebenza.Amandla wethegi ye-elekthronikhi ikakhulukazi avela emandleni omsakazo womfundi, futhi ibhethri yangaphakathi yethegi isetshenziswa kakhulu ukwenza inkambu yefrikhwensi yomsakazo.Amandla anganele.

Ukusebenza komaki be-rfid abangenzi lutho kuthintwa kakhulu usayizi wethegi, indlela yokushintshashintsha, inani lesekethe Q, ukusebenza kwedivayisi nokujula kokushintshashintsha.Omaki be-Passive abanawo amandla okwakhelwe ngaphakathi, futhi ikakhulukazi banikwa amandla yimishayo ethunyelwe umfundi we-RFID.
Uma isignali yefrikhwensi yomsakazo wenkundla kazibuthe lapho ithegi itholakala iqine ngokwanele, imininingwane yedatha egcinwe ku-chip ingathunyelwa kumfundi, ngokuvamile okuhlanganisa ulwazi lomazisi, okuhlosiwe okuhlosiwe noma idatha efanele yomnikazi. .
Nakuba ibanga lamathegi e-passive electronic lilifushane, izindleko ziphansi, ubukhulu buncane, impilo yesevisi yinde kakhulu, futhi ingasebenza ezindaweni ezihlukahlukene ezinokhahlo, futhi ingahlangabezana nezidingo zezinhlelo zokusebenza eziningi ezisebenzayo ngaphansi kokwehluka okuhlukile. imithetho yomsakazo.Isetshenziswa kakhulu emakethe.

Ungakhetha kanjani ithegi ye-RFID?
Amathegi e-elekthronikhi asebenzayo anebanga elide lokusebenza, futhi ibanga eliphakathi kwamathegi e-RFID asebenzayo nabafundi be-RFID lingafinyelela amashumi amamitha, noma ngisho namakhulu amamitha, kodwa athintwa amandla ebhethri, isikhathi sokuphila sifushane, futhi ivolumu inkulu nezindleko. ngaphezulu.
Amathegi e-passive electronic mancane ngosayizi, alula ngesisindo, aphansi ngezindleko futhi made empilweni.Angenziwa amajamo ahlukene njengamashidi noma amabhande, futhi asetshenziswe ezindaweni ezahlukene.Njengoba kungekho ugesi wangaphakathi, ibanga eliphakathi kwamathegi e-RFID nabafundi be-RFID lilinganiselwe, ngokuvamile phakathi kwamamitha ambalwa noma ngaphezulu kwamamitha ayishumi, ngokuvamile okudinga abafundi be-RFID bamandla aphezulu.
I-RFID esebenza kancane: Intengo imaphakathi, kodwa umsebenzi mncane uma kuqhathaniswa, futhi izidingo zohlelo lokusebenza zincane uma kuqhathaniswa.
