I-Radio Frequency Identification (RFID) iyiteknoloji engenantambo esebenzisa amaza omsakazo ukukhomba ngokuzenzakalelayo nokulandelela amathegi aqoshwe ezintweni.
I-Revolution Engabonakali: I-RFID (Radio Frequency Identification) izihlobanise buthule ngaphakathi kwendwangu yempilo yansuku zonke, ngokuvamile isebenza ngemuva kwezigcawu zezingqalasizinda ezibaluleke kakhulu emhlabeni. Kusukela ekhadini lokuhamba olithinta ukuze uye emsebenzini, kuya ekulandeleleni okungenazihibe kwempahla ezitolo zesimanje zokudayisa, i-RFID iyinjini ethule yokusebenza kahle.
I-Value Proposition: Amandla eqiniso e-RFID alele ekwazi kwayo ukuxhumanisa izwe elingokoqobo nelidijithali. Inikeza ukunemba kwempahla okungakaze kube khona (ngokuvamile okuthuthukisa ububanzi obusuka ku-65% kuya ku-99%), yenza izinqubo ezisebenzisa abasebenzi ngokuzenzakalelayo, futhi inikeza ukubonakala kwesikhathi sangempela okwenza ukwenza izinqumo eziqhutshwa idatha.
I-RFID ayizange ivele njengombono ophelele owodwa. Yakhiwa ngemibono eminingi emashumini eminyaka: ukubuyiswa kwamarada, ama-transponder asebenzayo, i-backscatter engenzi lutho, inkumbulo ye-semiconductor, futhi kamuva izindinganiso ezivulekile ze-EPC.
I-RFID yakhula ivela kumarada: amaza omsakazo ayathunyelwa, abuye asetshenziswe ebangeni, futhi ahunyushwe. Ngesikhathi seMpi Yezwe II, amasistimu okukhomba umngane-noma-isitha (IFF) engeza ama-transponder endizeni ukuze aphendule imiyalezo yokuqalisa (interrogation) kunokubuyisa kuphela.
Iphepha lika-Harry Stockman mayelana nokuxhumana ngokusebenzisa amandla abuyayo wachaza umqondo oyisisekelo we-backscatter: idivayisi ingakwazi ukuguqula i-carrier ebuyayo kunokwakha uqobo lwayo isignali yomsakazo enomthamo ogcwele.
Ilungelo lobunikazi le-transponder lika-Mario Cardullo lachaza i-tag enikwa amandla yisignali yokuqalisa (interrogation) enenkumbulo engashintshwa. Lesi sakhiwo siyisandulela sokuqala samasistimu e-RFID lapho i-tag ingesona isibuko esingaguquki kuphela.
Ilungelo lobunikazi lika-Charles Walton lokuhlonza ngogesi lisebenzise amasekethe e-resonant angenzi lutho (passive) aphazamisa inkambu yomfundi ngamafrikhwensi abhalwe ngekhodi. Lokhu kuchaza igatsha lekhadi lokufinyelela le-RFID: ubunikazi bungafakwa ku-load ye-RF ebekwa yinto engasebenzisi lutho (passive) eyethula emfuninini/umfundi (reader).
Imisebenzi kahulumeni kanye neyasemalabhorethri yathuthela i-RFID ekulandeleni izinto zenuzi, ekwenzeni ukuqoqwa kwentela ngokuzenzakalelayo, ekuboneni izilwane, nasekufinyeleleni kwezakhiwo. Lezi zinhlelo zibonise ukuthi ubunikazi ngamaza omsakazo bungakwazi ukusinda ezinkanjini zangempela, ezimotweni, emhlambini, nasezindaweni zomsebenzi.
Amasistimu e-UHF andise ibanga lokufunda, kanti i-MIT Auto-ID Center yaphushela ama-tag anentengo ephansi aphethe i-serial number, kuyilapho idatha yomkhiqizo ihlala ezinhlelweni zenethiwekhi. I-EPCglobal Gen2 yabe isinikeza imithombo yolayini wokuhlinzeka isisekelo esihlanganyelwe se-air-interface.
I-RFID yesimanje akuseyona into efunda i-tag kuphela. I-RAIN UHF, i-HF/NFC, ukuhlunga idatha emaphethelweni (edge filtering), ubunikazi ku-cloud, kanye nemibhalo yephasi lamkhiqizo (product passport) kuhlanganisa i-physics ye-RF nokuphathwa kwesoftware kanye nedatha yomjikelezo wempilo.
Ukuqonda i-RFID kudinga ukubheka i-physics eyisisekelo yama-radio waves kanye nokuqoqwa kwamandla. Lolu hlelo luthembele emgomeni we-'Backscatter' noma 'Inductive Coupling', kuye ngemvamisa.
Umfundi ukhiqiza i-carrier ye-RF eqhubekayo nge-antenna. Ama-tag angenzi lutho (passive) athatha ingxenye encane yaleyo nkambu ngokusebenzisa i-rectifier ne-charge pump ngaphakathi kwe-chip. I-chip iyavuka kuphela lapho amandla atholakele edlula umkhawulo wokuzwela, ngakho ibanga, inzuzo ye-antenna, ukulahleka kwekhebula, nokuma kwe-tag konke kubalulekile.
I-tag ye-UHF engenzi lutho (passive) ayiwakhiqizi umsakazo omusha. Iyashintsha i-load ku-antenna yayo phakathi kwezimo zokulingana (impedance states). Lokho kushintsha ukuthi kungakanani kwe-reader carrier okubuyiselwa emuva, kudale ama-sidebands amancane—umamukeli womfundi (reader receiver) wona uwayihlanganisa (demodulates) abe idatha ye-RN16, EPC, TID, noma inkumbulo yomsebenzisi.
Izinhlelo ze-LF ne-HF ikakhulukazi zisebenzisa i-magnetic inductive coupling enkambini eseduze. I-UHF RAIN RFID ikakhulukazi isebenzisa ukusabalala kwe-electromagnetic enkambini ekude. Ku-915 MHz, ubude begagasi buphakathi kuka-33 cm, ngakho ukufunda kwe-UHF okusebenzayo kulawulwa ukusabalala, ukubuyiswa, i-polarization, kanye ne-multipath.
Kudingeka kuvaleke izixhumanisi ezimbili. I-link eqondile (forward) kufanele ilethe amandla e-RF anele ukuze kusebenze i-tag. I-link ebuyayo (reverse) kufanele ibuyise i-backscatter eyanele ukuze idlule isisekelo sokuzwela somfundi. Ukufunda okwehlulekile kungavela kunoma yiluphi uhlangothi, yingakho ukulungisa amandla kuphela kungahlali kuyilungisa indlela yokusetshenziswa (deployment).
Amanzi amunca amandla e-UHF, kanti insimbi ibuyisela emuva noma yenza i-detune kuma-dipole tags ajwayelekile. Ama-tag ensimbi adinga i-spacer noma isakhiwo esiqondisiwe, ama-tag endwangu asebenzisa ijiyometri ye-antenna engamelana nokugoba, futhi imikhiqizo enamanzi ivamise ukufuna ukubekwa kude nendlela enokulahleka okuphezulu kakhulu.
Emikhakheni eminyene, abafundi (readers) abayizwa i-tag eyodwa ihlanzekile ngesikhathi esisodwa. Imijikelezo yokubala (inventory rounds) ye-EPC Gen2 isebenzisa i-anti-collision enama-slot. Ama-tag akhetha ama-slot, aphendule nge-RN16 engahleliwe, bese evezulula imininingwane ye-EPC ngemva kokuvunywa (acknowledgement). Ama-session flags asiza ukulawula ukuthi yiziphi ama-tag eziqhubeka nokuphendula.
Izinhlelo eziningi ze-passive RFID zisebenza ngomgomo othi 'Reader-Talks-First'. Umfundi ukhipha i-wave eqhubekayo (CW) yamandla e-RF. Lapho i-tag ingena kule nkundla, iyazithuthukisa futhi ilungisa ukubonakaliswa kwale wave ukuze ixhumane emuva.
I-Inductive Coupling (LF/HF): Isebenzisa inkundla kazibuthe. I-coil yomfundi kanye ne-tag coil zakha i-transformer. Isebenza kuphela ebangeni eliseduze (Near Field).
I-Radiative Coupling (UHF): Isebenzisa amaza e-electromagnetic. I-tag ibonisa ingxenye yamandla angenayo emuva kumfundi (Backscatter). Ivumela ukuxhumana okubanzi (Far Field).
I-Tag (Transponder): Yenziwe nge-microchip (IC) egcina idatha kanye ne-logic, exhunywe ku-antenna eqoqa amandla futhi idlulise amasignali. I-chip ne-antenna ziboshelwe ku-substrate (PET/Paper).
Umfundi (Interrogator): Ubuchopho bomsebenzi. Ikhiqiza isignali ye-RF, ithola impendulo ye-tag, futhi ihlukanisa idatha ye-binary. Abafundi bangase babe fixed (bafakwe eminyango ye-dock) noma abaphethe ngesandla (ngokusungula okuhambayo).
I-Antenna: Izwi nezindlebe zomfundi. Ilungisa inkundla ye-RF. Ama-antenna aqondaniswe ngendlela eyindilinga ahlukahlukene futhi angakwazi ukufunda ama-tag kunoma iyiphi indlela, kuyilapho ama-antenna aqondaniswe ngendlela eqondile enikeza ububanzi obude kodwa adinga ukuhlelwa kwe-tag okuthile.
Isebenzisa ukuxhumana kwe-inductive. Iqinile kakhulu eduze kwensimbi kanye noketshezi kodwa inebanga elifushane kakhulu kanye namanani edatha aphansi. Okujwayelekile kokufaka amathegi ezilwane kanye nokulawula ukufinyelela okulula.
Iphinda futhi isebenzise ukuxhumana kwe-inductive. Ilawulwa emhlabeni jikelele. I-NFC (Near Field Communication) iyingxenye ye-HF. Ilungele izinkokhelo eziphephile, amathikithi, kanye nokubandakanyeka kwabathengi ('thepha ukuze uxhume').
Isebenzisa ukuxhumana kwe-radiative. Okujwayelekile ochungechungeni lokuhlinzeka kanye nokuthengisa. Inikeza amabanga amade okufunda (afika ku-12m+), ukudluliswa kwedatha okusheshayo, kanye namakhono okufunda ngobuningi (amakhulu amathegi ngomzuzwana).
Akukho ibhethri. Inikwe amandla ngokuphelele yinkambu yomfundi. Impilo engapheli, izindleko eziphansi.
Ibhethri elingaphakathi le-on-board lokusakaza. Ibanga elide kakhulu (100m+) kodwa libiza kakhulu futhi linempilo elinganiselwe.
Ibhethri likhuphula isignali yokubuyisa kodwa aliyiqali. Izimo zokusebenzisa ezikhethekile.
Inombolo ye-serial eyingqayizivele, engashintshwayo eshiswe ngumkhiqizi. Ikhomba imodeli ye-chip.
Ibhange lememori elibhalekayo eligcina isihlonzi esiyingqayizivele sento (isb., i-SGTIN). Yilokhu abafundi abakufunayo.
Ibhange elingokuzithandela ledatha eyengeziwe efana nezinombolo ze-batch noma izinsuku zokuphelelwa yisikhathi.
Igcina Iphasiwedi Yokufinyelela (ukuvala idatha) kanye ne-Kill Password (ukuvala unomphela ithegi).
I-hardware ibona wonke amathegi izikhathi eziyi-100 ngomzuzwana. Umsebenzi we-software ukuhlunga lo 'msindo' ube yizenzakalo zebhizinisi ezinengqondo.
I-Middleware (njengezinga le-ALE) ihlala phakathi kwabafundi nezinhlelo zokusebenza. Ilungisa izilungiselelo zomfundi, iphatha i-firmware, futhi ihumushe amasiginali e-RF aluhlaza abe yidatha enengqondo.
Ukufundwa okuluhlaza kuhlungwa emaphethelweni. Ama-algorithm asusa ukufundwa okuphindwe kabili, ahlunge ama-tag alahlekile, futhi ahlanganise idatha ibe yizenzakalo ezinengqondo njengokuthi 'Into Ifikile' noma 'Into Ihambile' ngaphambi kokuthumela efwini.
Idatha ehlanzekile idluliselwa kuma-ERP (SAP, Oracle) noma ama-WMS ngama-API, ama-Webhook, noma i-MQTT. Lokhu kuvumelanisa ngesikhathi sangempela kuqinisekisa ukuthi 'I-Digital Twin' ihambisana neqiniso elingokomzimba.
Ikhuphula ukunemba kwempahla efinyelela ku-99% ngokubala umjikelezo wamasonto onamaminithi, hhayi amahora. Inika amandla amagumbi okulinganisa ahlakaniphile, izibuko zomlingo, nokusebenza okungenazihibe kwe-BOPIS (Thenga Ku-inthanethi, Thatha Esitolo).
Ukuqinisekiswa okuzenzakalelayo eminyango yezindawo zokulayisha ('ASNs'). Ukulandelela ngesikhathi sangempela Izinto Zokuthutha Ezibuyiselwayo (amaphali, ama-totes). Ukudlulisela ngaphandle kokuhlukaniswa ngesandla.
Ukulandeleka okugcwele kwe-Work-in-Progress (WIP). Ukulandelela amathuluzi ukuvimbela i-FOD (Foreign Object Debris). Umlando ozenzakalelayo wezingxenye ezihlanganisiwe.
Ukulandelela imithi enezinombolo ukugwema ukukopishwa. Ukulandelela impahla yezinto ezibalulekile njengamaphampu e-IV. Ukulandelela amathuluzi okuhlinza ukuze kuthobelwe ukuhlanjululwa.
Amathegi okurekhoda izinga lokushisa aqapha ukudla okonakalayo kusukela epulazini kuya emfolokweni. Uma imikhawulo idluliwe, ithegi ifaka ifulegi entweni, iqinisekisa ukuphepha kokudla nokuthobela imithetho.
Ngaphambi kokuthenga amathegi, hlaziya indawo. Ukuphazamiseka kwe-RF (amashelufu ensimbi, amapayipi amanzi, amanethiwekhi e-Wi-Fi) kumele ahlolwe ukuze kubekwe abafundi ngendlela efanele.
Ithegi iya kuphi? Ukufaka amathegi 'Ezingeni Lezinto' kunikeza ukubonakala okugcwele kodwa kubiza kakhulu. 'Izinga Lecala' noma 'Izinga Lephalethi' lishibhile kodwa alinawo ama-granular. Ukubekwa kwethegi kuvumelana ukuqinisekisa ukufundeka.
Ukufaka amathegi uketshezi (amanzi amunca i-RF) kanye nezinsimbi (insimbi ibonisa/idiliza i-RF) kudinga amathegi akhethekile. Amathegi ensimbi asebenzisa i-spacer ukudala i-mini-chamber yesignali.
I-ROI ivela ekongeni kwabasebenzi (isikhathi esincane ngama-96% sokubala isitoko), ukuncishiswa kokuncipha (ukwazi ukuthi yini ebiwe nokuthi nini), nokwanda kokuthengisa (izinto zangempela eshalofini).
Ama-tag angakhiywa noma 'abulawa' (akhutshazwe unomphela) e-Point of Sale. Ama-tag e-Cryptographic avimbela ukukopisha ukuze kulwiwe nokukopisha.
Umhlaba usebenza ku-GS1 EPC Gen2 (ISO 18000-6C). Lokhu kuqinisekisa ukuthi i-tag ethengwe e-Vietnam ingafundwa ngumfundi e-US.
Ngokungafani ne-GPS, i-passive RFID ayikwazi ukulandelela abantu ebangeni elide. Kodwa-ke, ubumfihlo bomthengi buvikelwe ngezici 'Kill' kanye nezimpawu ezicacile.
Imithetho ezayo ye-EU izodinga ukuthi imikhiqizo ibe nerekhodi ledijithali lokusimama kwayo. I-RFID izothwala le datha yokugaywa kabusha kanye nomnotho oyindilinga.
Ukuqhubekela 'ngaphandle kwe-chipless' noma izimpondo zekhabhoni eziphrintiwe ukunciphisa izindleko kanye nomthelela emvelweni, okwenza i-RFID isebenze ngisho nezinto zokudla ezibiza kancane.
Amamodeli e-Machine Learning ahlaziya izigidi zamaphuzu edatha avela kubafundi be-RFID ukuze babike izithiyo zokuhlinzekwa ngaphambi kokuthi zenzeke.
I-RFID imele Ukuhlonzwa Ngemvamisa Yomsakazo. Nakuba igama lingase lizwakale liyinkimbinkimbi, umqondo ulula kakhulu: ubuchwepheshe obungenantambo obusebenzisa amagagasi omsakazo ukuhlonza ngokuzenzakalelayo nokulandelela amathegi aqoshwe ezintweni. Cabanga ngayo njengenguqulo engenantambo yebhakhodi. Kodwa-ke, ngokungafani nebhakhodi elidinga ukubonwa ukuze liskenwe, i-RFID isebenzisa amagagasi omsakazo ukuze 'ikhulume' nesifundi, okuyivumela ukuthi ihlonzwe ngaphandle komugqa oqondile wokubona.
Isistimu ye-RFID ayiyona idivayisi eyodwa; iyithimba labadlali abathathu abakhulu abasebenza ndawonye. Okokuqala, unayo i-RFID Tag (noma i-transponder), okuyi-microchip encane eqoshwe ku-antenna efakwa entweni ofuna ukuyilandelela. Okwesibili, unayo i-RFID Reader (noma i-interrogator), esebenza njengengqondo ethumela amasignali omsakazo ukuze ithole amathegi. Okokugcina, kukhona i-Antenna, esebenza njengelizwi nezindlebe zesifundi, isakaza isignali futhi ilalele impendulo yethegi. Ngokubambisana, bakha iluphu yokuxhumana engenazihibe.
Umlingo we-RFID wenzeka ngenqubo ebizwa ngokuthi 'ukuhlehla' noma 'ukuxhumana'. Kuqala lapho i-Reader ithumela isignali yamagagasi omsakazo nge-antenna yayo, ifuna noma yimaphi amathegi aseduze. Lapho ithegi ye-RFID engenzi lutho ingena kule ndawo, i-antenna yayo ithatha lawo mandla kusignali yesifundi. Lawa mandla avusa i-chip encane ngaphakathi kwethegi. Ithegi bese isebenzisa lawo mandla afanayo ukubonisa isignali emuva esifundini, ithwala inombolo yayo eyingqayizivele yokuhlonza. Isifundi sibamba lokhu kubonakala, sihlaziye inombolo, futhi siyithumele kusistimu yekhompyutha ukuze icutshungulwe - konke kwenzeka ngesikhashana.
Umehluko omkhulu ukuthi athola kuphi amandla abo. Amathegi e-Passive yiwona avamile futhi athengekayo; awanayo ibhethri ngaphakathi. Ahlala ethule aze 'avuswe' ngamandla avela kumagagasi omsakazo wesifundi se-RFID. Ngenxa yokuthi awanayo ibhethri, ashibhile futhi ahlala phakade. Amathegi e-Active, ngakolunye uhlangothi, anebhethri yawo eyakhelwe ngaphakathi. Lokhu kubavumela ukuthi bamemeze isignali yabo kakhulu futhi kude, bafinyelele ngaphezu kwamamitha angu-100, kodwa makhulu, abiza kakhulu, futhi ekugcineni azophelelwa ibhethri.
Ithegi i-Semi-passive (ebizwa nangokuthi i-Battery-Assisted Passive noma i-BAP) liyingxube. Linobhethri elincane, kodwa ngokungafani nethegi esebenzayo, alisebenzisi lelo bhetri ukusakaza isignali. Kunalokho, ibhethri lisetshenziselwa kuphela ukugcina i-chip isebenza noma ukunika amandla izinzwa ezisendizeni (njengomrekhoda wokushisa). Isancike kusignali yomfundi ukuthi ibuyisele emuva. Lo mklamo uyinika ukuzwela okungcono nokwethembeka kokufunda kunethegi ejwayelekile engenzi lutho, ngaphandle kwezindleko eziphezulu nokukhipha amandla ethegi esebenza ngokugcwele.
I-RFID ayiyona 'usayizi owodwa olungela bonke'; isebenza 'emigwaqeni' ehlukene noma ebangeni lemvamisa kuye ngomsebenzi. Imvamisa Ephansi (LF) isebenza ku-125–134 kHz; inebanga elifushane kodwa iqine, ilungele ukulandelela izilwane. Imvamisa Ephezulu (HF) isebenza ku-13.56 MHz; lokhu kuhlanganisa ubuchwepheshe be-NFC obusetshenziselwa izinkokhelo namakhadi okhiye. Okokugcina, Imvamisa Ephezulu Kakhulu (UHF) isebenza ku-860–960 MHz; leli yigunya le-supply chain kanye nokuthengisa ngoba linikeza amabanga amade okufunda (afika ku-12m) kanye nesivinini esisheshayo sokudlulisa idatha.
Ibanga lokufunda lihluka kakhulu kuye ngohlobo lwethegi nemvamisa esetshenziswayo. Kumathegi e-LF kanye ne-HF/NFC, ibanga lifushane ngamabomu - ngokuvamile ukuthinta ibanga elingafika kumamitha angu-1 - ngenxa yokuphepha nokunemba. Amathegi e-Passive UHF, okuyijwayelekile yohlu lwempahla, ngokuvamile angafundwa ukusuka kumamitha angu-5 kuya kwangu-12. Uma udinga ibanga eliqinile, amathegi e-Active anebhethri angafundwa kalula ukusuka kumamitha angu-100+, okwenza alungele ukulandelela amaloli noma iziqukathi zokuthumela ezingadini ezinkulu.
Nakanjani! Lokhu kungenye yamandla amakhulu e-RFID uma kuqhathaniswa namabhakhodi. Isithwebuli sebhakhodi singafunda ikhodi eyodwa ngesikhathi, kodwa isifundi se-RFID singakwazi ukuhlonza amakhulu amathegi ngesikhathi esisodwa ngemizuzwana embalwa nje. Leli khono libizwa ngokuthi 'ukuskena ngobuningi' noma 'ukuphikisana'. Kusho ukuthi ungaswayipha isifundi esiphathwayo phezu kwebhokisi eligcwele amahembe angu-50 futhi uwalande ngaso leso sikhathi ngaphandle kokuvula ibhokisi.
Cha, futhi lokho kuyinzuzo enkulu. Amagagasi omsakazo anethuba lokungena ezintweni ezivamile. Lokhu kusho ukuthi isifundi se-RFID singakwazi 'ukubona' ithegi ngisho noma ingaphakathi ebhokisini lekhadibhodi, ingcwatshwe emthwalweni wezingubo, noma ifihlwe ngemuva kwepheneli yepulasitiki. Uma nje into ingeyona insimbi (eyibonisa amasignali) noma amanzi (awamunca), amagagasi omsakazo azohamba kuwo ukuze afunde ithegi.
Yebo, ziyizitha zemvelo zezimpawu ze-RFID ezijwayelekile. Izindawo zensimbi zenza njengesibuko samagagasi omsakazo, ziwabuyise futhi zivimbele ithegi ukuthi ingashaji. Uketshezi (njengamanzi ebhodleleni noma umzimba womuntu) lumunca amandla, linciphisa isignali. Kodwa-ke, onjiniyela bakuxazulule lokhu ngamathegi akhethekile 'On-Metal' asebenza njengesikhala sokuphakamisa i-antenna ngaphezulu kwendawo yensimbi, nangokushuna amathegi ngokuqondile ukuze asebenze kangcono eduze noketshezi. Ngakho-ke, nakuba kuyinselele, iyinye engaxazululeka.
Cabanga ngebhakhodi njengepuleti lelayisense okufanele uthathe isithombe esicacile ukuze usifunde - udinga ukukhanya okuhle nomugqa oqondile wokubona. I-RFID injenge-E-ZPass toll transponder; idinga nje ukuba seduze nomfundi ukuze itholwe. Amabhakhodi 'afundwa kuphela' futhi ajwayelekile (akhomba uhlobo lomkhiqizo), kanti ama-tag e-RFID angaskenwa ngobuningi ngaphandle kokubonwa, angagcina izinombolo ze-serial eziyingqayizivele zento ngayinye, futhi amanye angabhala kabusha ngedatha entsha.
Leli yiphuzu elivamile lokudideka: NFC (Near Field Communication) empeleni uhlobo oluthile lwe-RFID. Isebenza ebangeni le-High Frequency (HF). Umehluko omkhulu usekusetshenzisweni nasebangeni. I-RFID ejwayelekile (ikakhulukazi i-UHF) yakhelwe ibanga nevolumu - ukulandela amabhokisi endaweni yokugcina impahla ukusuka kumamitha ayi-10. I-NFC yakhelwe ukusondela nokuphepha - ukudlulisa idatha ngokuphephile ngamasentimitha ambalwa nje, njengokuthepha ifoni yakho ukuze ukhokhe noma ukubhangqa isipika se-Bluetooth.
Ngokusekelwe ku-tag ngayinye, yebo. Ibhakhodi imahhala ngempela - iyinki nje ephepheni. I-tag ye-RFID engenzi lutho ihlanganisa i-microchip ne-antenna, ebiza noma yikuphi kusuka kumakhekhe angu-5 kuya kwangu-15. Kodwa-ke, ukubheka kuphela izindleko ze-tag kuphuthelwa isithombe esikhulu. Inani le-RFID livela ekongeni okukhulu kwabasebenzi (ukuskena i-inventory ngemizuzu esikhundleni sezinsuku) kanye nokuthuthuka okunembile (ukunciphisa ukulahlekelwa ukuthengisa ezintweni ezingekho esitokweni). Emahhovisi amaningi, lokhu kongiwe kokusebenza kudlula izindleko zama-tag.
Abathengisi basebenzisa i-RFID ukuze baqhubeke nokuphatha i-inventory yesikhathi sangempela, ukuvimbela ukwebiwa, kanye nezinqubo zokuphuma ngokushesha. Kusiza ekuqinisekiseni ukuthi amashalofu ahlala egcwele futhi kunciphisa isikhathi esidingekayo sokuthatha isitoko ngesandla. Esikhundleni sokubala ngesandla okwenzeka kanye ngonyaka, abasebenzi besitolo bangenza ukubala komjikelezo wamasonto onke ngemizuzu besebenzisa induku ephathwayo. Lokhu kuqinisekisa ukuthi uhlelo lwazi kahle ukuthi yini esitokweni, okwenza izici ezifana 'nama-Smart Fitting Rooms' (ancoma izinto ezihambisanayo) futhi kwenza 'Thenga Ku-inthanethi, Thatha Esitolo' (BOPIS) kuthembeke ngoba idatha yesitoko ilungile ngempela.
Ku-logistics, isivinini nokunemba kuyikho konke. Ama-RFID portals abekwa e-dock doors ukuze njengoba i-forklift iqhubela i-pallet yezimpahla elolini, uhlelo lufunda ngokuzenzakalelayo yonke into eyodwa kuleyo pallet, luqinisekisa ukuthunyelwa ngokumelene ne-oda ngaso leso sikhathi. Ludala umzila wedijithali wekhathoni ngalinye, luqinisekisa ukuthi izimpahla ezifanele ziya endaweni efanele ngaphandle kokudinga umuntu ukuthi ame futhi aqondise isithwebuli sebhakhodi ebhokisini ngalinye.
Ekunakekelweni kwezempilo, i-RFID ingaba ngumsindisi wempilo ngokoqobo. Isetshenziselwa ukulandela impahla enenani eliphezulu njengamaphampu okufaka kanye nezihlalo zabakhubazekile ukuze abahlengikazi bangachithi isikhathi besesha. Kubalulekile ukuphathwa kwemithi, kuqinisekisa ukuthi izidakamizwa ziyiqiniso futhi aziphelelwe yisikhathi. Isetshenziselwa futhi ukuphepha kwesiguli ngama-wristband ukuqinisekisa ukuthi ngubani ngaphambi kokuhlinzwa, futhi nokulandela amasiponji okuhlinzwa ukuqinisekisa ukuthi akukho okushiywe ngemuva ngemuva kokuhlinzwa.
Kungenzeka ukuthi uyisebenzisa nsuku zonke ngaphandle kokuqaphela! Ikhadi eliyinhloko olithinta ukuze ungene ehhovisi lakho noma i-fob oyisebenzisela isakhiwo sakho se-apartment isebenzisa LF noma HF RFID. Uma ubamba ikhadi eduze komfundi odongeni, umfundi unika amandla i-chip yekhadi, uhlola ikhodi yayo ye-ID eyingqayizivele ngokumelene nohlu lwedatha lwabasebenzisi abagunyaziwe, futhi uma ithola okufanayo, ivula umnyango. Kuphephile, kulula ukuphatha (amakhadi angasebenzi ngokushesha), futhi kulula.
Ukuvikeleka kuyahluka ngohlobo lwethegi, kodwa i-RFID yesimanje inezinketho eziqinile. Amathegi ayisisekelo sokusungula asebenza njengepuleti lelayisense - lifundeka esidlangalaleni kodwa alinamqondo ngaphandle kokufinyelela ku-database yangemuva. Kodwa-ke, ezinhlelweni ezizwelayo, sisebenzisa ama-crypto-tags anokubethela okusezingeni eliphezulu okungenakukopishwa. Ngaphezu kwalokho, amathegi angavikelwa ngephasiwedi ukuvimbela ukubhala okungagunyaziwe, okusho ukuthi akekho ongabhala ngaphezulu idatha yakho. Ukuze kube nemfihlo yabathengi, amathegi angathola 'Umyalo Wokubulala' ngesikhathi sokuthengisa, awenze angasebenzi unomphela.
Lena inganekwane ethandwayo ekhuthazwa ngamabhayisikobho, kodwa iqiniso linesabekayo kakhulu. Ngenkathi amakhadi amadala okusondela ayelula, amakhadi esikweletu esesimanje angenayo ukuthintana namaphasiphothi asebenzisa ukubethela okuyinkimbinkimbi kanye namakhodi ashintshayo ashintshayo. Lokhu kusho ukuthi idatha iyashintsha ngakho konke ukuthengiselana. Noma ngabe othile onomfundi onamandla wakwazi ukuxhumana nekhadi lakho, idatha abayitholile izoba yikhodi yesikhathi esisodwa engasizi ngalutho ekwenzeni ukuthengiselana okuzayo. Ingozi incane kakhulu emhlabeni wangempela.
Ikusasa limayelana nokuxhumeka yonke indawo. Siqhubekela emhlabeni lapho cishe yonke into ebonakalayo - kusukela ezingutsheni ozigqokayo kuya ekudleni okuthengayo - inobunikazi bedijithali. Siqhubekela ku-'Integrated IoT', lapho idatha ye-RFID ihlanganiswa ne-AI kanye ne-cloud analytics ukudala izindawo zokugcina impahla ezihlakaniphile nezindawo zokuthengisa ezizenzakalelayo ngokugcwele. Sibona futhi ukukhuphuka kwamathegi anobungane bemvelo enziwe ngephepha kunepulasitiki ukunciphisa imfucuza yepulasitiki.
