Ukuphathwa komcimbi kungenye yezindawo ezibalulekile zokuphathwa kwesimanje. Ingathuthukisa kahle ukusebenza kahle kwenhlangano kanye nekhwalithi yokusebenza yomcimbi, iqinisekise ukuqhubeka kahle komcimbi, futhi ifinyelele ngempumelelo umgomo womcimbi. Ngokuthuthukiswa kobuchwepheshe be-RFID, emicimbini yezemidlalo, izingqungquthela zebhizinisi nezinye izimo, kunganciphisa amandla abasebenzi kanye nezinsizakusebenza, konge isikhathi, futhi kusizwe abahleli bemicimbi nabaphathi bathuthukise ukusebenza kahle kokuphatha futhi kunciphise amaphutha.
1.Ukuphathwa kwemicimbi yezemidlalo
Ubuchwepheshe be-RFID ngokuvamile busetshenziselwa ukuhlela isikhathi emicimbini yokugijima emgwaqeni njengamarathoni amakhulu, ama-half marathon, namakhilomitha ayi-10. Ngokwe-AIMS, amathegi e-RFID esikhathi aqala ukungeniswa emijahweni yemarathon nguChampion Chip waseNetherlands ngonyaka ka-1995. Emiqhudelwaneni yokugijima emigwaqweni, kunezinhlobo ezimbili zamathegi esikhathi, eyodwa iboshelwa entanjeni yezicathulo; enye inanyathiselwe ngqo ngemuva kwebhibhu yenombolo futhi ayidingi ukugaywa kabusha. Amathegi asetshenziswayo asetshenziswa emijahweni eminingi yokugijima emgwaqeni ukuze kongiwe izindleko. Phakathi nomjaho, abafundi bekhaphethi bavamise ukubekwa ekuqaleni, ekupheleni kanye namaphoyinti okujika abalulekile, njll. ukuze kukhiqizwe insimu kazibuthe endaweni encane. I-antenna yethegi idlula endaweni kazibuthe ukuze ikhiqize okwamanje ukuze inike amandla i-chip ukuze ithegi ikwazi ukudlulisa amasignali. Ukuze i-antenna kakhaphethi ikwazi ukuthola futhi irekhode i-ID nesikhathi se-chip edlula kukhaphethi. Idatha yawo wonke amakhaphethi ihlanganiswa ibe isofthiwe ekhethekile ukuze kuhlungwe imiphumela yomdlali ngamunye futhi kubalwe isikhathi se-chip, njll.
Ukuhlaziywa Kokukhethwa Komkhiqizo
Ngenxa yokuthi i-marathon ibanjelwa ngaphandle futhi izixuku ziminyene, idinga isikhathi esinembile nokuqashelwa kwamabanga amade. Kulolu hlelo, izixazululo ze-UHF RFID zivame ukusetshenziswa, njenge-NXP UCODE 9, imvamisa yokusebenza ngu-860~960MHz, ISO 18000-6C kanye ne-EPC C1 Gen2 ehambisanayo, umthamo we-EPC 96bit, ububanzi bokushisa bokusebenza: -40 °C kuya ku-+85 °C, inezinzuzo zejubane eliphezulu, ukufundwa kweqembu, ukungqubuzana komaka abaningi, ibanga elide, ikhono eliqinile lokulwa nokuphazamiseka, izindleko eziphansi kanye nosayizi womaka omncane. Amalebula e-electronic e-RFID angananyathiselwa ngemuva kwebhibhu yenombolo yomsubathi. Amakomiti amaningi ahlela imicimbi azosebenzisa ilebula ye-RFID eyisipele eyodwa, ngoba lokhu kunganciphisa amathuba okufundwa okungamanga okubangelwa ukuphazamiseka komaka. Ihlinzeka ngohlelo lokusekelayo uma ngabe enye yalezi zisetshenziswa ihluleka.
Ezisetshenziswa ezingokoqobo, ngenxa yokuthi ilebula ye-RFID inamathiselwe ngemuva kwebhayibheli lenombolo futhi ihlukaniswa nomzimba womuntu ingcezu yezemidlalo kuphela, i-dielectric constant ehlobene yomzimba womuntu inkulu, futhi ukuthintana eduze kuzomunca amagagasi kagesi, okuzothinta ukusebenza kwe-antenna. Ngakho-ke, sizonamathisela ungqimba lwegwebu kuthegi ethi Inlay ukuze sigcine uthi lokumaka lusebangeni elithile ukusuka emzimbeni womuntu ukuze sinciphise umthelela wokufunda umaka. I-Inlay isebenzisa i-antenna efakwe i-aluminium kanye ne-PET. Inqubo yokufaka i-aluminium yenza izindleko zehlise. I-antenna isebenzisa i-dipole antenna enesigamu-wave enesakhiwo esinwetshiwe emikhawulweni yomibili: ikhulisa amandla emisebe, noma ingaqondwa njengokwandisa ukumelana kwayo nemisebe. I-radar cross-section inkulu futhi amandla e-backscattering anamandla. Umfundi uthola amandla aqinile aboniswa ithegi ye-RFID, futhi angasetshenziswa ngisho nasezimweni eziyinkimbinkimbi kakhulu.
Mayelana nokukhethwa kweglue, ngoba iningi lamapuleti enziwe ngephepha le-DuPont elinendawo emangelengele, futhi abasubathi bazokhipha umjuluko omningi phakathi nemiqhudelwano, amathegi e-RFID adinga ukusebenzisa ingcina esebenzisa izinyibilikisi zemvelo njengendlela qeda futhi ugcobe i-adhesive. Izinzuzo yilezi: Inokumelana okuhle kwamanzi, i-trong viscosity, akulula ukuchichima kokunamathelayo, imelana nokushisa okuphezulu futhi ingajwayela ukumaka kwangaphandle.
