Imvamisa ye-RFID Ehlukile Inesimiso Somsebenzi Esihlukile

 

Insimbi, Uketshezi, kanye Nenkinga Yezindlela Eziningi Ezikhungweni Zangempela

 

Insimbi idala ama-eddy currents asusa imvamisa ye-resonant yethegi kude nebhendi yokusebenza yomfundi. Lo mphumela wokuhlukanisa wenza inlay ye-UHF evamile efundeka kahle ekhadini ingabonakali eshalofini lensimbi.-kumathegi ensimbi anezendlalelo zokushiya isikhala kanye nejometri ye-antenna elungisiwexazulula lokhu, kodwa lindela ukukhokha u-$0.80-2.50 umaka ngamunye uma uqhathanisa no-$0.08-0.15 wokufakwa okujwayelekile (intengo yomsabalalisi ka-2024, ubuningi obungu-10K+).

 

Ukuphazamiseka koketshezi kulandela indlela ehlukile. Silinganise lokhu ngokuqondile phakathi nomshayeli wezokuthutha wesiphuzo: ibhodlela elilodwa le-PET elingu-500ml elibekwe ku-10cm ukusuka kuthegi, umfundi ebangeni elingamamitha angu-2, lehlise izinga lokufunda eliphumelelayo lisuka ku-98% laya ku-34% lisebenzisa ama-dipole inlays ajwayelekile ku-915 MHz. Amasistimu e-LF asebenza ngo-134 kHz awazange abonise ukuwohloka okulinganisekayo ekusethweni okufanayo kokuhlolwa{9}}okungakho ama-chips okufakelwa kwezilwane esebenzisa lelo bhande.

 

I-Multipath inkinga ethile ye-UHF-engavamile ukuvela kumadokhumenti omthengisi. Amagagasi kagesi agxuma ama-rack ensimbi, phansi kukakhonkolo, nezinto zokusebenza, afika kumfundi ngezindlela eziningi. Uma lezi zindlela ziphazamisa ngokulimazayo, uthola izindawo ezingenalutho lapho amathegi angafundiwe.

 

Sibhale lokhu ngesikhathi sokufakwa kwesitoreji esibandayo ngaphandle kwase-Rotterdam: izindawo eziyisikhombisa ezingenalutho ezihlukile endaweni engu-400m², ngayinye engu-15-20cm ububanzi ngokusekelwe kugridi yokuskena ngeZebra MC3390R ephathwa ngesandla ekulungisweni okungu-50cm. Ukuhambisa iphalethi amayintshi ayisithupha kubuyise amathegi ekuxhumaneni. Ukulungiswa kwakudinga ukushintshwa kusukela kolayini{7}}abahlukanisiwe baye koyisiyingi{13}}okuthiwa abamhlophe, okunciphise ukufakwa okusebenzayo kothiyo ngalunye cishe ngo-30% futhi kwasiphoqa ukuthi sengeze izifundi zephothali ezimbili ezengeziwe. Izingxenyekazi zekhompuyutha ezengeziwe nokufakwa: €3,200. Isifundo: uma indawo yakho ine-metal racking ebalulekile, sebenzisa ibhajethi yokuhlola indawo ye-RF ngaphambi kokuphothula ukufakwa komfundi. Ezindaweni ezicabangela ukusetshenziswa kwe-UHF RFID ezindaweni{14}}ezisindayo, lezi zindleko zenhlolovo zincane uma ziqhathaniswa nokuxazulula inkinga ngemva kokuthunyelwa.

 

 

I-Global Frequency Allocation kanye Nocupho Lokuthobela

 

Ukwabiwa kwe-UHF spectrum kuyahlukahluka ngokwanele phakathi kwezifunda lapho okokusebenza okuthengelwe imakethe eyodwa kungase kungabi semthethweni kwenye:

• i-America esenyakatho: 902-928 MHz, kufika ku-4W EIRP
• EYurophu: 865-868 MHz, 2W ERP esiphezulu nge-ISO/IEC 18000-63 ngayinye
• Japan: 920 MHz ibhendi, ejwayelekile 2012
• China: 920-925 MHz

Amathegi ngokwawo ngokuvamile ayisifunda-i-agnostic{1}}Iphrothokholi ye-EPC Gen2 igxuma kububanzi obugcwele obungu-860-960 MHz. Isicupho sokuthobela sisekuthengweni kwabafundi. I-Zebra FX9600 ethengwe nge-firmware yase-US ayikwazi ukusebenza ngokusemthethweni e-EU ngaphandle kokukhanyisa kabusha, futhi amanye amamodeli omfundi awakusekeli nhlobo ukumiswa kabusha kwenkambu.

 

Elinye lamakhasimende ethu, umkhiqizi wezinto zikagesi ezithengwayo elinama-DC e-Texas nase-Poland, lifunde lokhu lapho indawo yabo yase-Poland ithola abafundi abayisi-8 abangakwazi ukuphinda bamiswe. U-15% abawulondolozile ekuthengeni kumnikezeli oyedwa wase-US ubabize u-200% wezingxenyekazi zekhompuyutha ezishintshayo kanye nokubambezeleka kokuba bukhoma-. Ngokukhishwa{6}}kwezifunda eziningi, cacisa okuhlukile kwe-firmware yesifunda ku-PO noma usebenze nabasabalalisi abagcina izinguqulo ze-EU/US/APAC ngokuhlukene.

 

I-HF ku-13.56 MHz kanye ne-LF ku-125-134 kHz ivunyelaniswa emhlabeni jikelele nemikhawulo yamandla engaguquki.Kumaphrojekthi ochungechunge lokunikezela ngempahla enqamula izifunda ezintathu noma ngaphezulu zokulawula, lokhu kufana kungadlula ibanga elifushane lokufunda, ikakhulukazi uma okunye kuphatha ama-SKU abafundi abaningi.

 

 

Ukukhetha Imvamisa Yezimo Eziqondile Zokuthunyelwa

 

Nansi ingqondo yesinqumo esiyisebenzisa ngempela namakhasimende:

Isibalo se-crossover yezindlekokuncike kakhulu ekuminyana kwabafundi. Ukuze uthole-ukusetshenziswa kwendawo eyodwa okuvamile (umfundi oyedwa ongashintshi ohlanganisa indawo efundwayo engu-20-30m² efundwayo, izinti ezine), izindleko eziphelele zesistimu ye-HF zilingana noma zidlula i-UHF ngaphansi kwamathegi acishe abe ngu-5,000. Ngaphezu kwamathegi angama-50,000, i-UHF iwina ngenani eliphelele ngoba inani lethegi liyabusa. Ububanzi be-5K-50K budinga ukumodela ngesibalo sangempela somfundi kanye nevolumu yethegi-indawo edinga amaphuzu okufunda ayi-12 izofinyelela inzuzo yezindleko ze-UHF ngokushesha kakhulu kunoyedwa odinga amabili.

 

Ukwenza Isinqumo Sokuthengwa Kwempahla

 

Umbuzo awukona ukuthi iyiphi ibhendi yefrikhwensi ye-RFID engcono emhlabeni wonke. Yilapho umshini wokuhlanganisa kazibuthe kagesi ohambisana nezingqinamba ezithile zendawo yokuthunyelwa, izindawo zokulawula ezihilelekile, kanye nesamba sesabelomali sephrojekthi okuhlanganisa nengqalasizinda.

 

Ngezinhlelo zokusebenza eziqondile-zokulawula ukufinyelela, inkokhelo,{1}}uhlu lwendlela echaziwe{2}}inketho ngokuvamile isobala phakathi nemizuzu emihlanu yokubuyekeza izimo zesayithi. Ngokusetshenziswa okuyinkimbinkimbi okuhlanganisa izinto ezixubile,{4}}imisebenzi enqamula imingcele, noma izimfuneko zebanga lokufunda elingajwayelekile, inqubo yokukhetha izuza ocwaningweni lwesayithi ye-RF kanye nokumodela izindleko ngaphambi kokuzibophezela ekuthengeni ihadiwe.
