Incuro zitandukanye za RFID zifise ingingo ngenderwako y'akazi itandukanye

 

Ivyuma, Amazi, n’Ingorane y’Inzira nyinshi mu Bibanza Vy’ukuri

 

Ivyuma birarema amashanyarazi y’inzira y’amazi (eddy currents) ahindura incuro z’ijwi ry’ivyo bimenyetso biva ku nzira umusomyi akoresha. Ivyo bituma igikoresho gisanzwe c’UHF gisomwa neza ku makarata kitaboneka ku gitereko c’icuma.Ku-ivyuma bifise ibipande vy'imirongo n'ubuhinga bwa antene bwahinduwegutorera umuti ivyo, ariko witege kwishura $0.80-2.50 ku tag ugereranije n’$0.08-0.15 ku bikoresho bisanzwe (2024 igiciro c’abatanga, 10K+ ubwinshi).

 

Intambara y’amazi ikurikira uburyo butandukanye. Ivyo twabipimye ataco bimaze mu gihe c’igerageza ry’ivy’ibinyobwa: icupa rimwe ry’imiti 500ml rya PET ryari riri ku rugero rwa 10cm uvuye ku kimenyetso, umusomyi ku ntambwe ya metero 2, ryagabanyije igipimo co gusoma neza kuva kuri 98% gushika kuri 34% hakoreshejwe ubuhinga bwa dipole inlays ku 915 MHz. LF systems zikora kuri 134 kHz ntizerekanye ukuntu zishobora gusenyuka mu gihe kimwe c’igerageza-ni co gituma ibice vy’ibikoko bikoresha iyo nzira.

 

Multipath ni ikibazo kidasanzwe ca UHF-kiboneka gake mu nyandiko z'abaguzi. Imiraba y’umuyagankuba iraguruka iva ku bitanda vy’ivyuma, hasi muri beton be n’ibikoresho, igashika ku musomyi biciye mu nzira nyinshi. Iyo izo nzira zibangamiye mu buryo busambura, uronka uturere tutagira ikintu aho ama tags adasoma.

 

Ivyo twavyanditse mu gihe c’ugushiraho ububiko bukonje hanze ya Rotterdam: uturere indwi dutandukanye tw’ubusa mu burebure bwa 400m2, umwe wese afise ubwaguke bwa 15-20cm bishingiye ku gupima uruzitiro n’igikoresho ca Zebra MC3390R gifatwa mu minwe ku 50cm. Kwimurira paleti amasentimetero atandatu vyatumye ama tags asubira mu guhanahana amakuru. Ivyo vyasaba ko duhindura antene ziri mu murongo-zifise amabara menshi tuja ku ma antene y’umurongo-afise amabara abiri, ivyo bikaba vyagabanyije ubushobozi bwa antene imwe imwe ku bice nka 30% maze bituma twongerako ibindi bikoresho bibiri vy’ugusoma urugi. Ibindi bikoresho n'ugushiraho: €3,200. Icigwa: nimba ikibanza cawe gifise ivyuma vyinshi, nushireho ingengo y’imari y’ubushakashatsi ku kibanza ca RF imbere y’uko uheza gushiramwo abasomyi. Ku bibanza biriko birazirikana gukoresha UHF RFID ku bidukikije vy’ivyuma-biremerera, iki kiguzi c’ubushakashatsi ni gito ugereranije n’ugutorera umuti ingorane inyuma yo gukoresha.

 

 

Ugutanga incuro kw'isi yose n'umutego wo kwubahiriza

 

Ugutanga urumuri rwa UHF biratandukanye cane hagati y’uturere ku buryo ibikoresho vyaguriwe isoko rimwe bishobora kuba bitemewe n’amategeko mu rindi:

• Amerika ya ruguru: 902-928 MHz, gushika ku 4W EIRP
• Uburayi: 865-868 MHz, 2W ERP irengeye ku ISO/IEC 18000-63
• Ubuyapani: Umurongo wa 920 MHz, washizweho mu 2012
• Ubushinwa: 920-925 MHz

Ivyiyumviro ubwavyo muri rusangi ni akarere-atagira ubwenge-EPC Gen2 porotokole igendagenda mu rwego rwose rwa 860-960 MHz. Umutego wo kwubahiriza amategeko uri mu gutanga amasoko y’abasomyi. Zebra FX9600 yaguzwe na firmware ya Amerika ntishobora gukora mu buryo butegekanijwe n’amategeko mu Muryango w’Ubumwe bw’Uburayi ata gusubira guca ibibatsi, kandi ibigereranyo bimwe bimwe vy’abasomyi ntibishigikira gusubira gutunganya ivy’umurima na gato.

 

Umwe mu bakiriya bacu, umuhinga mu vy’ubuhinga bwa none afise ama DC muri Texas no muri Polonye, ​​ivyo yarabimenye igihe ikigo cabo co muri Polonye caronka abasomyi 8 batashobora gusubirwamwo. 15% bazigamye bagura ku mucuruzi umwe wo muri Amerika vyabatwaye 200% mu gusubirira ibikoresho no gutevya go-live. Ku bijanye n'ugutangaza mu karere kenshi, sobanura uburyo bwo gukoresha porogaramu y'akarere muri PO canke ukore n'abatanga amakuru babika amaverisiyo ya EU/US/APAC atandukanye.

 

HF ku 13.56 MHz na LF ku 125-134 kHz zihuye kw’isi yose n’imipaka y’ububasha idahinduka ..Ku migambi y’uruhererekane rw’ibikoresho ijabuka uturere dutatu canke turenga, ukwo guhuza gushobora kurenga urugero rugufi rwo gusoma, cane cane iyo ubundi buryo ari ugucungera SKU z’abasomyi benshi.

 

 

Guhitamwo incuro ku bintu vyihariye vyo gukoresha

 

Ehe ingingo dukoresha mu vy'ukuri n'abaguzi:

Ibara ry'igicirobivana cane n’uburemere bw’abasomyi. Ku bijanye n’ugukoresha akarere kamwe - (umusomyi umwe adahinduka apfutse akarere k’ugusoma 20-30m2, ama antene ane), igiciro cose c’uburyo bwa HF kingana canke kiruta UHF iri munsi y’ibimenyetso nka 5.000. Hejuru y’ama tags 50.000, UHF iratsinda kugiciro cose kuko igiciro c’ama tags ari co kiganza. 5K-50K range isaba gukora modele n’igitigiri c’abasomyi nyaco n’umubare w’ibimenyetso-ikigo gikeneye amanota 12 yo gusoma kizotera inyungu y’igiciro ca UHF vuba cane kuruta kimwe gikeneye bibiri.

 

Gufata ingingo yo gutanga amasoko

 

Ikibazo si ikihe bandi y’incuro za RFID ari nziza kw’isi yose. Ni uburyo bwo gufatanya amashanyarazi bujanye n’ingorane zidasanzwe z’ibidukikije vyo gukoresha, ububasha bujejwe gucungera, n’ingengo y’imari yose y’umugambi harimwo n’ibikorwa remezo.

 

Ku bikorwa vyoroshe-ubugenzuzi bw'ukwinjira, kwishura, gusobanura-ububiko bw'inzira-uguhitamwo akenshi kugaragara mu minota itanu y'ugusubiramwo ivy'urubuga. Ku bikorwa bikomeye birimwo ibikoresho bivanze, ibikorwa vyo kujabuka-imipaka, canke ibisabwa bidasanzwe vyo gusoma, uburyo bwo guhitamwo burangukira ku bushakashatsi bw’aho RF iri no gushushanya igiciro imbere y’uko umuntu yiyemeza kugura ibikoresho.
