Keeb Kwm & Daim Ntawv Thov
Lub ntiaj teb kev lag luam logistics loj hlob tas li, tab sis muaj ntau yam teeb meem hauv tus qauv logistics ib txwm muaj. Piv txwv li: Kev cia siab rau kev ua haujlwm tes yuav ua rau cov khoom tsis raug sijhawm lossis tsis tau suav. Tib lub sijhawm, nws siv sijhawm ntev los nkag thiab tawm hauv lub tsev rau khoom, cov khoom ntws qeeb, thiab nws nyuaj rau kev teeb tsa cov ntaub ntawv khoom. Kev siv RFID thev naus laus zis rau lub kaw lus xa khoom, ua ke nrog kev siv cov software systems xws li Manufacturing Execution System, Warehouse Management System thiab Logistics Execution System, tuaj yeem daws cov teeb meem no thiab ua tau raws li qhov xav tau ntawm cov saw hlau xa khoom. Nws tuaj yeem paub txog kev taug qab cov khoom los ntawm kev tsim khoom, kev khaws khoom, kev thauj mus los, kev faib khoom, mus rau kev muag khoom, thiab txawm tias rov qab ua tiav. Nws tsis tsuas yog txhim kho qhov kev ua haujlwm ntawm tag nrho cov saw hlau xa khoom, tab sis kuj txo qhov yuam kev ntau heev. Kev txhim kho qib kev txawj ntse tau dhau los ua ib feem tseem ceeb ntawm kev txhim kho ntawm cov logistics niaj hnub thiab cov saw hlau xa khoom.
1. Kev Txuas Ntxiv Rau Kev Tsim Khoom
Txhua yam khoom muaj ib daim nplaum rau UHF passive rfid cim npe nrog cov ntaub ntawv tseem ceeb sau rau ntawm nws, thiab cov nyeem RFID tau teeb tsa ntawm ntau qhov txuas tseem ceeb ntawm cov kab ntau lawm. Thaum cov khoom lag luam nrog UHF passive rfid tag dhau los ntawm tus nyeem RFID ruaj khov ua ntu zus, tus nyeem ntawv yuav nyeem cov ntaub ntawv ntawm cov khoom thiab xa cov ntaub ntawv mus rau MES system, thiab tom qab ntawd txiav txim siab qhov xwm txheej tiav ntawm cov khoom lag luam hauv kev tsim khoom thiab qhov xwm txheej ua haujlwm ntawm txhua qhov chaw ua haujlwm.
2. Kev Txuas Rau Chaw Khaws Khoom
Txuas Cov ntawv nplaum RFID ntev ntev passivemus rau qhov chaw ntawm cov khoom thiab pallets hauv lub tsev rau khoom. Cov cim ntse muaj cov lus qhia txog cov khoom, cov lej serial thiab lwm yam ntaub ntawv. Thaum cov khoom nkag thiab tawm hauv lub tsev rau khoom, cov nyeem RFID nyob ntawm qhov nkag thiab tawm tuaj yeem nyeem cov ntawv lo no. Thiab sau thiab ua tiav tsis siv neeg. Cov thawj coj tsev rau khoom tuaj yeem nkag siab cov ntaub ntawv tseeb ntawm cov xwm txheej khoom muag los ntawm WMS system.
3. Kev Txuas Mus Los
TxuasCov ntawv lo rau RAIN UHF RFID rau cov khoom, thiab teeb tsa cov nyeem RFID ntawm chaw nres tsheb npav, chaw nres tsheb ciav hlau, chaw nres nkoj, tshav dav hlau, qhov tawm ntawm txoj kev loj, thiab lwm yam. Thaum tus nyeem RFID nyeem cov ntaub ntawv ntawm daim ntawv lo, nws tuaj yeem xa cov ntaub ntawv qhov chaw ntawm cov khoom mus rau qhov chaw xa khoom hauv lub sijhawm tiag tiag. Yog tias cov ntaub ntawv ntawm cov khoom (qhov hnyav, ntim, ntau npaum li cas) pom tias tsis raug, tus nyeem RFID tuaj yeem tsav mus nyeem daim ntawv cim qhia. Yog tias cov khoom tsis pom tom qab tshawb nrhiav zaum ob, cov lus ceeb toom yuav raug xa mus rau qhov chaw xa khoom kom tiv thaiv cov khoom kom tsis txhob ploj lossis raug nyiag.
4. Kev Txuas Rau Kev Faib Khoom
Thaum cov khoom muajRFID daim ntawv lo rau kev xa khoomThaum cov khoom raug xa mus rau qhov chaw faib khoom, lub tshuab nyeem RFID yuav nyeem cov ntaub ntawv ntawm txhua yam khoom ntawm lub pallet faib khoom. Lub kaw lus software cuam tshuam sib piv cov ntaub ntawv ntawm cov khoom nrog cov ntaub ntawv xa khoom, nrhiav pom qhov tsis sib xws, thiab tiv thaiv kev xa khoom yuam kev. Tib lub sijhawm, qhov chaw khaws khoom thiab qhov xwm txheej xa khoom ntawm cov khoom tuaj yeem hloov kho tshiab. Nrhiav seb koj qhov kev xa khoom pib thiab mus qhov twg, nrog rau lub sijhawm tuaj txog, thiab ntau ntxiv.
1.5 Kev Txuas Rau Kev Muag Khoom
Thaum ib yam khoom raug txuas nrog ib qho RFID daim ntawv nplaum, tsis yog tsuas yog lub sijhawm siv tau ntawm cov khoom tuaj yeem saib xyuas los ntawm cov software system, tab sis RFID nyeem ntawv ntsia ntawm lub txee them nyiaj kuj tseem siv tau los luam theej duab thiab them nqi rau cov khoom, uas ua rau cov khoom ua haujlwm zoo dua. Nws txo cov nqi zog ua haujlwm thiab txhim kho qib kev txawj ntse.
Kev Tshawb Fawb Txog Kev Xaiv Khoom
Thaum xaiv ib yam khoom, peb yuav tsum xav txog qhov permittivity ntawm cov khoom uas yuav tsum tau txuas, nrog rau qhov impedance ntawm lub chip thiab lub antenna. Feem ntau ntawm cov cim npe siv hauv kev lag luam logistics dav dav yog RFID cim npe rau cov thawv xa khoom, uas tau lo rau ntawm cov thawv ntawv. Yuav kom tiv thaiv cov khoom raug thauj mus los hauv cov thawv ntawv kom tsis txhob puas tsuaj, cov thawv ntawv logistics feem ntau yuav tsis raug rau qhov kub thiab txias lossis av noo ntev heev hauv ib puag ncig. Yog tsis muaj cov kev cai tshwj xeeb, peb cov cim npe logistics xaiv yog:
1) Cov khoom siv saum npoo yog daim ntawv kos duab lossis daim ntawv thermal, thiab cov kua nplaum yog kua nplaum dej, uas tuaj yeem ua tau raws li qhov xav tau thiab tswj tus nqi.
2) Cov khoom feem ntau loj dua thiab xav tau ntau cov ntaub ntawv kom luam tawm rau ntawm qhov chaw, yog li cov cim loj raug xaiv. (Xws li: 4 × 2”, 4 × 6”, thiab lwm yam.)
3)RFID daim ntawv lo rau kev xa khoom yuav tsum muaj qhov nyeem tau ntev, yog li ntawd yuav tsum muaj lub antenna loj nrog lub antenna loj. Qhov chaw cia khoom kuj yuav tsum loj, yog li siv cov chips nrog EPC nco ntawm 96bits thiab 128bits, xws li NXP Ucode 8, Ucode9, Impinj Monza 730, M750. Lub Alien H9 chip kuj siv, tab sis vim nws qhov chaw cia khoom loj dua ntawm 688 bits thiab tus nqi siab dua, muaj tsawg dua kev xaiv.
Cov Khoom Siv XGSun
Qhov zoo ntawm RFID cov cim npe rau kev taug qab logistics Muab los ntawm XGSun: Cov ntawv loj, cov yob me, ua raws li ISO18000-6C protocol, tus nqi nyeem cov ntaub ntawv ntawm daim ntawv tuaj yeem ncav cuag 40kbps ~ 640kbps. Raws li RFID anti-collision technology, tus naj npawb ntawm cov ntawv uas tuaj yeem nyeem tau tib lub sijhawm tuaj yeem ncav cuag li 1,000. Nws muaj kev nyeem thiab sau ceev ceev, kev ruaj ntseg ntawm cov ntaub ntawv siab, thiab ntau yam kev nyeem ntev hauv qhov zaus ua haujlwm (860 MHz -960 MHz), uas tuaj yeem ncav cuag 10 meters. Nws muaj peev xwm khaws cov ntaub ntawv loj, yooj yim nyeem thiab sau, kev hloov pauv ib puag ncig zoo heev, tus nqi qis, kev ua haujlwm siab, lub neej ntev thiab ntau yam kev siv. Nws kuj txhawb nqa kev hloov kho.
