Kev sib piv ntawm RFID tsab ntawv cim npe thiab cov barcodes
Peb yog ib lub tuam txhab luam ntawv loj hauv Shenzhen Tuam Tshoj. Peb muaj cov phau ntawv luam tawm, phau ntawv xov xwm luam ntawv, phau ntawv luam ntawv, phau ntawv nyuaj, phau ntawv luam tawm, phau ntawv luam tawm, phau ntawv luam tawm, lub thawv ntim, daim qhia ntawv, txhua yam ntawm PVC, cov ntawv luam tawm, ntawv sau cia, hom tshwj xeeb ntawv xim luam tawm khoom, kev ua si cardand li ntawd.

Bar code tshuab, ib qho ntawm cov cim tsis paub zoo, tau loj hlob ntau tshaj 30 xyoo dhau los, tab sis ob peb lub tuam txhab tau kam txais yuav nws. Mus txog 1984, cov khw muag khoom loj xws li Wal-Mart yuam kom lawv cov neeg siv los txais yuav kev siv tshuab. Daim ntawv thov cov cai tau nthuav dav sai heev. Tam sim no, raws li lub ntiaj teb cov khoom muag muag khoom noj khoom haus tshaj plaws Wal-Mart, Chris, thiab Metro, cov khoom uas muab los ntawm lawv tus neeg yuav tsum muaj RFID (Cov Ntawv Xov Xwm Xov Tooj). Qhov no yog undoubtedly qhov kev thov kev lag luam los txhawb Wal-Mart los xaiv ntau hom kev qhia paub tsis siv neeg tuaj yeem. Piv nrog rau kev sib tiv tauj txoj kev siv tshuab bar code, RFID yog kev siv cov cim tsis siv neeg tsis paub zoo. Nws muaj hwj chim, muaj peev xwm loj, thiab nyeem tau ntawv zoo thiab ua kom tiav zoo dua rau hauv kev ua khoom muag.
Los ntawm txoj cai tshuab bar code rau RFID technology, lub tsev qiv ntawv automation tau mus txog ib txoj kev tawm mus ntev tom qab qhov kev hloov ntev: nrog rau RFID technology, lub tsev qiv ntawv hauv Singapore tau nce cov nqi qiv nyiaj los ntawm 30 zaug thiab tau txais kev cawmdim 28 lab daus las txhua xyoo. Tus nqi zog rau 2,000 cov neeg ua haujlwm.
Taw qhia rau 1 daim npav barcode thiab RFID hluav taws xob
1.1 qhov system barcode
Bar code system yog ib qho kev cai binary uas muaj cov kab khiav ua haujlwm thiab cov khoob khawm. Ib cov kab sib txawv ntawm cov dav thiab vos kab los tau muab txhais ua cov lej / ntawv sau. Nws nyeem los ntawm laser scanner (uas peb tam sim no hu ua "cwj mem lub teeb"), piv txwv li los ntawm ntau lub reflections ntawm lub laser ntawm cov kab dub thiab dawb khoob. Txawm hais tias lawv lub cev yog tib yam, muaj kev sib txawv meej ntawm cov cai ntawm cov cai ntawm kaum hom kev cai siv niaj hnub siv, thiab lub tsev qiv ntawv siv txoj cai 39.
1.2 RFID hluav taws xob
RFID electronic tag muaj ib tus kav hlau txais xov (lossis coil) thiab ib lub cim ntim. Lub nti yog ib qho-chip system nrog wireless transceiver thiab cia kev khiav dej num. Nws khaws cov ntaub ntawv hluav taws xob rau hauv ib hom qauv thiab tuaj yeem txheeb xyuas cov ntaub ntawv raws li xav tau. RFID electronic cov cim npe yog cais hauv cov cim npe tawm thiab cov cim npe. Lub tsev qiv ntawv siv cov cim npe tawm passive (cov cim npe nram no hais txog cov ntawv cim npe). Tom qab tau txais lub teeb liab los ntawm tus nyeem ntawv, cov ntawv xa cov ntaub ntawv khaws cia rau hauv lub nti los ntawm lub zog tau txais los ntawm kev ntxias tam sim no, yog li ntawd nws tseem hu ua passive tag. RFID electronic daim ntawv tuaj yeem ua rau ntau yam duab thiab qhov ntau thiab tsawg, nws tsis tshua muaj nyias, nws yooj yim, thiab tuaj yeem ua kom tau ntau yam ntaub ntawv ntawm lwm yam hlau, thiab muaj kev nyab xeeb.
2 Kev sib piv ntawm qhov zoo thiab qhov tsis zoo ntawm ob
Thaum lub teeb cwj mem nyeem cov cai ntawm txoj cai, qhov kev ua lag luam yog tsawg tsawg, qhov ua tau tsawg tsawg, thiab ib lub bar yog ua tiav ib qho, uas yog ib qho yooj yim ua yuam kev, kev siv zog loj, thiab muaj kev cuam tshuam los ntawm tej yam kev mob. Nyob rau hauv kev sib piv, RFID hluavtom muaj ntau qhov zoo: nws nyeem ntawv Nws tsis xav pom lub teeb qhov chaw, muaj penetrability, tau ncaj qha nyeem cov ntaub ntawv los ntawm lwm cov ntaub ntawv, muaj peev xwm ua tau ntau yam ntawm RF cim npe tib lub sij hawm, kev ua haujlwm, simpligate kev siv zog, thiab taug qab yam khoom txoj hauj lwm nyob rau ntawm lub sij hawm, nrog rau qhov yuam kev tsawg heev thiab tej yam puag ncig. Tej yam tsis zoo. Tus tshaj tawm thiab pom ntawm ob yuav pom nyob rau saum toj rooj.
3 Cov teeb meem hluav taws xob hauv RFID hluav taws xob thiab txoj kev loj hlob zeem muag
Los ntawm bar code rau RFID lossis, nws twb tau paub txog txoj kev loj hlob tas mus li, kev tshawb kawm thiab kev txhim kho ntawm txoj cai bar - bar code + RFID tag - RFID tag. RFID technology thiab tsev qiv ntawv cov ntaub ntawv qhia zoo tshaj plaws rau kev tsim cov tsev qiv ntawv uas muaj digital thiab automated, tab sis tseem muaj qee cov teeb meem hauv RFID cov cim npe uas yuav tsum tau daws:
(1) Cov ntsiab lus tsis pub twg paub: kev tswj qhov kev tswj, txo tus nqi txo, kev ruaj ntseg yog heev nthuav.
(2) Cuam tshuam hauv kev siv tshuab: Raws li kev soj ntsuam xyuas los ntawm lub koom haum Auto-ID qhov chaw ua haujlwm, txawm tias muaj ob lo lus sau, 3% ntawm RFID nyeem tsis tau; tsuas yog 78% ntawm daim ntawv nrog rau ib daim ntawv lo yog nyeem. Tawm. Tsis tas li ntawd, RFID cov cim npe thiab cov nyeem ntawv muaj cov kev taw qhia thiab RF cov teeb tseg tau yooj yim thaiv los ntawm cov khoom, uas yog ib qho tseem ceeb rau yav tom ntej ntawm kev tsim technology hauv RF.
(3) Kev txo nqi: Tam sim no, tus nqi ntawm RFID tsab ntawv cim npe yog tseem heev. RFID tsab ntawv cim npe yog muab tso rau hauv 0, 1, 2, 3, 4, thiab 5. Qhov ntau dua tus naj npawb, ntau zog, Tus nqi tseem ntau dua.
(4) Formulation thiab kev siv ntawm cov qauv hauv thoob ntiaj teb: Sib koom nrog RFID; daim ntawv teev lus qhia hauv qab yog IS015693 tus qauv, 128b ~ EEPROM, 13.56 MHz kev khiav haujlwm. Daim ntawv thov ntawm RFID electronic tags nyob rau hauv lub tsev qiv ntawv, txawm tias nws tseem muaj qee cov teeb meem, kuv ntseeg tias yav tom ntej, nrog kev ua kom zoo dua qub kev siv tshuab, qhov kev kawm ntawm tsev qiv ntawv automation, txawj ntse, thiab digitization yuav loj hlob tuaj, thiab nws txoj kev loj hlob kev cia siab yog Broad.
