Iindaba

Iithegi ze-elektroniki ze-RFID zenziwe ngeethegi, iincwadi zokufunda ze-rfid kunye nokugcinwa kwedatha kunye neenkqubo zokucubungula.Ngokweendlela ezahlukeneyo zonikezelo lwamandla, i-RFID inokwahlulwa ibe ziindidi ezintathu: iRFID esebenzayo, i-semi-active RFID, kunye ne-RFID yokwenziwa.Imemori yitshiphu ene-eriyali.Ulwazi olukwi-chip lunokusetyenziswa ukuchonga into ekujoliswe kuyo.Umsebenzi ophambili kukuchonga iimpahla.

Umahluko phakathi kwethegi esebenzayo, enesiqingatha-esebenzayo kunye ne-passive ye-RFID ngolu hlobo lulandelayo:

1. Iingcamango

I-rfid esebenzayo inikwa amandla ngebhetri eyakhelweyo, udidi lweethegi zombane ezichazwa ngeendlela ezahlukeneyo zobonelelo lwamandla eethegi ze-elektroniki, kwaye idla ngokuxhasa ukuchongwa komgama omde.I-RFID esebenzayo iSemi-esebenzayo sisimakishi esikhethekileyo esidibanisa iingenelo zeethegi zeRFID ezisebenzayo. kunye neethegi ze-RFID zokwenziwa.Kwiimeko ezininzi, ihlala ingena kwindawo eleleyo kwaye ingasebenzi, kwaye ayithumeli zimpawu zeRFID kwihlabathi langaphandle.Kuphela xa ingaphakathi kuluhlu lwesignali yokuvula ye-activator ye-frequency ephezulu, ithegi esebenzayo iya kuvula kwaye isebenze i-rfid ye-Passive, oko kukuthi, i-tag ye-radio frequency tag ithatha imo yokusebenza yomthwali, inamandla okuchasa ukuphazamiseka, abasebenzisi banokwenza ukufunda nokubhala idatha eqhelekileyo, ukusebenza kakuhle kukulungele kakhulu kwiqonga lesicelo esikhethekileyo, kwaye umgama wokufunda unokufikelela ngaphezu kweemitha ezili-10.

2. Umgaqo wokusebenza

Ithegi ye-elektroniki esebenzayo ithetha ukuba amandla omsebenzi wethegi anikezelwa yibhetri.Ibhetri, inkumbulo kunye ne-eriyali kunye zenza ithegi ye-elektroniki esebenzayo.Ngokwahlukileyo kwifom yokuvula yefrikhwensi yerediyo yokwenziwa, i-RFID esebenzayo ixhotyiswe ngento yokugcina ezimeleyo ngaphakathi.Amandla agcweleyo, kwaye usathumela ulwazi ngokuseta ibhendi yefrikhwensi phambi kokuba kufakwe ibhetri.
Iithegi ezisebenzayo zinomgama omkhulu wokusebenza, umthamo omkhulu wokugcina, kunye namandla ekhompyuter anamandla ngenxa yonikezelo lwamandla oluqhubekayo, kwaye banokuthumela ngenkuthalo imiqondiso equlethe ulwazi olusebenzisanayo kwiifrikhwensi ezithile kumfundi.Ukuthembeka kokusebenza kuphezulu, kwaye umgama wokuhambisa umqondiso ude.Nangona kunjalo, ngenxa yempembelelo yamandla ebhetri, ubomi beethegi ezisebenzayo bukhawulelwe, ngokubanzi kuphela iminyaka eyi-3-10.Ngokusetyenziswa kwamandla ebhetri kwithegi, umgama wokuhanjiswa kwedatha uya kuba mncinci kwaye ube mncinci, oya kuchaphazela ukusebenza okuqhelekileyo kwenkqubo yeRFID.

I-semi-active rfid, iithegi ze-elektroniki eziqhelekileyo ezisebenzayo zisebenza kwi-433M frequency band okanye i-2.4G frequency band.Isebenza kakuhle emva kokuba ivuliwe.Umgama wokuvula we-activator ye-high-frequency activator ulinganiselwe, kwaye awukwazi ukuqaliswa ngokuchanekileyo kumgama omncinci kunye noluhlu oluncinci.Ngale ndlela, ithegi esebenzayo ibekwe kunye ne-activator ye-low-frequency activator njengendawo yesiseko, kunye neendawo ezahlukeneyo zesiseko zifakwe kwiindawo ezahlukeneyo, kwaye ke indawo enkulu isebenzisa umfundi omde ukuchonga nokufunda umqondiso, kwaye emva koko ulayishe umqondiso kwiziko lolawulo ngeendlela ezahlukeneyo zokulayisha.Ngale ndlela, yonke inkqubo yokuqokelela umqondiso, ukuhanjiswa, ukusetyenzwa, kunye nesicelo kugqityiwe.
Ngokufana nethegi esebenzayo, ithegi ye-semi-active nayo inebhetri ngaphakathi, kodwa ibhetri ibonelela kuphela ngenkxaso yesekethe egcina idatha kunye nesekethe egcina i-voltage yokusebenza ye-chip, kwaye isetyenziselwa ukuqhuba isiphaluka esidibeneyo. ngaphakathi kwethegi ukugcina imo yokusebenza.
Phambi kokuba ithegi ye-elektroniki ingene kwimeko yokusebenza, ibikwimo eleleyo, elingana nethegi yokwenziwa.Ukusetyenziswa kwamandla ebhetri ngaphakathi kwithegi kuncinci kakhulu, ngoko ke ibhetri ingahlala iminyaka emininzi okanye ukuya kuthi ga kwiminyaka eyi-10.Xa ithegi ye-elektroniki ingena kwindawo yokusebenza yomfundi, ivuselelwa ngumqondiso werediyo othunyelwa ngumfundi, kwaye ithegi ingena kwimeko yokusebenza.Amandla ethegi yombane avela ikakhulu kumandla kanomathotholo omfundi, kwaye ibhetri yangaphakathi yethegi isetyenziswa ikakhulu ukwenza indawo yerediyo.Amandla angonelanga.

Ukusebenza kweethegi ze-fid esebenzayo kuchatshazelwa kakhulu bubungakanani bethegi, indlela yokumodareyitha, ixabiso lesekethe Q, ukusebenza kwesixhobo kunye nobunzulu bomodulation.Iithegi zePassive azinawo unikezelo lwamandla okwakhelwe ngaphakathi, kwaye ubukhulu becala zinikwa amandla ngamaqadi athunyelwe ngumfundi weRFID.
Xa isiginali yerediyo ye-electromagnetic field ibekwe kuyo ithegi yomelele ngokwaneleyo, ulwazi lwedatha olugcinwe kwichip lunokuthunyelwa kumfundi, ngokuqhelekileyo kubandakanya ulwazi lwethegi yesazisi, itekeni ekujoliswe kuyo okanye idatha efanelekileyo yomnini. .
Nangona umgama weethegi ze-elektroniki ze-passive umfutshane, ixabiso liphantsi, ubungakanani buncinci, ubomi benkonzo bude kakhulu, kwaye bunokusebenza kwiindawo ezahlukeneyo ezinzima, kwaye banokuhlangabezana neemfuno zeenkqubo ezininzi zesicelo ezisebenzayo phantsi kweendlela ezahlukeneyo. imimiselo kanomathotholo.Isetyenziswa kakhulu kwimarike.

Ungayikhetha njani ithegi yeRFID?
Iithegi ze-elektroniki ezisebenzayo zinomgama omde wokusebenza, kwaye umgama phakathi kweethegi ze-RFID ezisebenzayo kunye nabafundi be-RFID banokufikelela kumashumi eemitha, okanye namakhulu eemitha, kodwa bachatshazelwe ngamandla ebhetri, ixesha lokuphila lifutshane, kwaye umthamo mkhulu kunye neendleko. phezulu.
Iithegi ze-elektroniki ze-Passive zincinci ngobukhulu, zilula ngobunzima, ziphantsi kweendleko kwaye zinde ebomini.Zingenziwa kwiimilo ezahlukeneyo ezifana namaphepha okanye amaqhosha, kwaye zisetyenziswe kwiindawo ezahlukeneyo.Ekubeni kungekho mbane wangaphakathi, umgama phakathi kweethegi ze-RFID kunye nabafundi be-RFID ulinganiselwe, ngokuqhelekileyo ngaphakathi kweemitha ezimbalwa okanye ngaphezulu kweemitha ezilishumi, efuna ngokubanzi abafundi be-RFID bamandla aphezulu.
Semi-active RFID: Ixabiso liphakathi, kodwa umsebenzi umncinci, kwaye iimfuno zesicelo esisebenzayo zincinci.
