Yintoni iRfid Electronic tag?
Iithegi ze-elektroniki ze-RFID zisetyenziswa kakhulu kubomi bemihla ngemihla kunye nemisebenzi yemveliso yomntu wonke. Ayiphuculi kakhulu ukusebenza kwemveliso kuphela, kodwa izisa uncedo oluninzi kubomi bemihla ngemihla babantu. Ke namhlanje ndiza kukwazisa iithegi ze-elektroniki ze-RFID kuwe.
Zisebenza njani iithegi ze-elektroniki ze-RFID
Iithegi zeRFID zisebenzisa iifrikhwensi zikanomathotholo ezingasebenzi ngeengcingo ukwenza uthungelwano lwedatha olungendlela-mbini phakathi komfundi kunye nekhadi lefrikhwensi yerediyo ukuphumeza injongo yokuchonga okujoliswe kuko kunye notshintshiselwano ngedatha. Okokuqala, emva kokuba ithegi ye-elektroniki ye-RFID ingene kumhlaba wemagnethi, ifumana isiginali yerediyo ethunyelwa ngumfundi, kwaye emva koko isebenzisa Amandla afunyenwe ngoku i-induced athumela ulwazi lwemveliso olugcinwe kwitshiphu (ithegi yokwenziwa okanye ithegi yokwenziwa), okanye ithegi ithumela ngokusebenzayo umqondiso wokuphindaphinda okuthile (ithegi esebenzayo okanye ithegi esebenzayo), kwaye umfundi uyalufunda ulwazi alugqibe. Ekugqibeleni, ithunyelwa kwisixokelelwano solwazi esisembindini ukwenzela ukusetyenzwa kwedatha efanelekileyo.
Ukuqulunqwa kweethegi ze-elektroniki ze-RFID
Ithegi ye-elektroniki ye-RFID epheleleyo inamacandelo amathathu: umfundi/umbhali, ithegi ye-elektroniki, kunye nenkqubo yolawulo lwedatha. Umgaqo wayo wokusebenza kukuba i-Reader ikhupha amandla amaza erediyo yefrikhwensi ethile ukuqhuba isekethe ukuthumela idatha yangaphakathi. Ngeli xesha, uMfundi ngokulandelelana Fumana kwaye utolike idatha kwaye uyithumele kwisicelo sokuqhubekeka okuhambelanayo.
1. Umfundi
Umfundi sisixhobo esifunda ulwazi kwithegi ye-elektroniki ye-RFID okanye sibhale ulwazi olufuna ukuligcina kwithegi. Ngokuxhomekeke kulwakhiwo kunye nobuchwepheshe obusetyenzisiweyo, umfundi unokuba sisixhobo sokufunda/sokubhala kwaye liziko lolawulo lolwazi kunye nokusetyenzwa kwenkqubo yeRFID. Xa inkqubo yeRFID isebenza, umfundi uthumela amandla erediyo yerediyo ngaphakathi kwendawo ukuze enze intsimi ye-electromagnetic. Ubungakanani bendawo buxhomekeke kumandla othumelo. Iithegi ezingaphakathi kwendawo yokugubungela umfundi zishukunyiswa, zithumele idatha egcinwe kuzo, okanye ziguqule idatha egcinwe kuzo ngokwemiyalelo yomfundi, kwaye inokunxibelelana nenethiwekhi yekhompyuter nge-interface. Amacandelo asisiseko omfundi ahlala ebandakanya: i-antenna ye-transceiver, i-frequency generator, i-loop-locked loop, i-modulation circuit, i-microprocessor, imemori, i-demodulation circuit kunye ne-peripheral interface.
(1) I-antenna ye-Transceiver: Thumela imiqondiso yerediyo yerediyo kwiithegi, kwaye ufumane imiqondiso yokuphendula kunye nolwazi lwethegi olubuyiswe ziithegi.
(2) Ijeneretha yokuphindaphinda: ivelisa i-frequency yokusebenza kwenkqubo.
(3) I-loop evaliweyo yesigaba: yenza isignali efunekayo yokuthwala.
(4) Isekethe yokumodareyitha: Layisha umqondiso othunyelwe kwithegi kwi-carrier wave kwaye uyithumele ngesekethe yerediyo.
(5) I-Microprocessor: yenza isignali ukuba ithunyelwe kwithegi, ichaza isignali ebuyisiwe yithegi, kwaye ithumele idatha edibeneyo kwiprogram yesicelo. Ukuba isixokelelwano sinoguqulelo oluntsonkothileyo, kufuneka kwakhona yenze umsebenzi wokucima ukuntsonkotha.
(6) Imemori: igcina iinkqubo zomsebenzisi kunye nedatha.
(7) Isekethe ye-Demodulation: Imodareyitha isiginali ebuyisiwe yithegi kwaye iyithumele kwi-microprocessor ukusetyenzwa.
(8) Ujongano lweperipheral: lunxibelelana nekhompyuter.
2. Ileyibhile ye-elektroniki
Iithegi ze-elektroniki zenziwe ngee-antenna ze-transceiver, iisekethe ze-AC / DC, iisekethe zokuchithwa kwe-demodulation, i-logic control circuits, imemori kunye neesekethe zokumodareyitha.
(1) I-antenna ye-Transceiver: Fumana imiqondiso evela kumfundi kwaye uthumele idatha efunekayo kumfundi.
(2) Isekethe ye-AC/DC: Isebenzisa i-electromagnetic field energy ekhutshwa ngumfundi kwaye iyikhuphe nge-voltage stabilizing circuit ukubonelela ngamandla azinzileyo kwezinye iisekethe.
(3) Isekethe ye-Demodulation: susa umthwali kwi-signal efunyenweyo kwaye udibanise uphawu lokuqala.
(4) Isekethe yokulawula ingqiqo: icacisa umqondiso ovela kumfundi kwaye ibuyisela umqondiso ngokweemfuno zomfundi.
(5) Imemori: ukusebenza kwenkqubo kunye nokugcinwa kwedatha yokuchonga.
(6) Isiphaluka sokumodareyitha: Idatha ethunyelwe yi-logic control circuit ilayishwe kwi-antenna kwaye ithunyelwe kumfundi emva kokulayishwa kwisekethe yokumodareyitha.
Iimpawu zeRFID iithegi zombane
Ngokubanzi, itekhnoloji yokuchonga irediyo yerediyo inezi mpawu zilandelayo:
1. Ukusetyenziswa
Itekhnoloji yethegi yeRFID ixhomekeke kumaza ombane kwaye ayifuni kunxibelelwano lwasemzimbeni phakathi kwamaqela amabini. Oku kuvumela ukuseka unxibelelwano kunye nonxibelelwano olupheleleyo ngokuthe ngqo kungakhathaliseki ukuba luthuli, inkungu, iplastiki, iphepha, umthi kunye nemiqobo eyahlukeneyo.
2. Ukusebenza kakuhle
Isantya sokufunda nokubhala se-RFID yenkqubo yethegi yombane ikhawuleza kakhulu, kwaye inkqubo yosasazo ye-RFID idla ngokuthatha ngaphantsi kwe-100 milliseconds. Abafundi be-RFID be-Frequency High-frequency banokuchonga kwaye bafunde imixholo yeethegi ezininzi ngaxeshanye, bephucula kakhulu ukuhanjiswa kolwazi.
3. Ukwahluka
Ithegi nganye yeRFID yohlukile. Ngembalelwano enye-to-enye phakathi kweethegi ze-RFID kunye neemveliso, ukujikeleza okulandelayo kwemveliso nganye kunokulandelwa ngokucacileyo.
4. Ubulula
Iithegi zeRFID zinesakhiwo esilula, izinga eliphezulu lokuqaphela, kunye nezixhobo zokufunda ezilula. Ngokukodwa njengoko itekhnoloji ye-NFC isiya ithandwa ngakumbi kwii-smartphones, ifowuni nganye yomsebenzisi iya kuba yeyona nto ilula yokufunda iRFID.
Kukho ulwazi oluninzi malunga neethegi ze-elektroniki ze-RFID. I-Joinet igxile kuphando kunye nophuhliso lwetekhnoloji ephezulu eyahlukeneyo iminyaka emininzi, incede uphuhliso lweenkampani ezininzi, kwaye izimisele ukuzisa izisombululo ezingcono ze-RFID tag yombane kubathengi.
