Dab tsi yog Txoj Cai Ua Haujlwm Thiab Cov Txheej Txheem Kev Ua Haujlwm ntawm RFID Labels?

Lub hauv paus ntsiab lus ua haujlwm ntawm electronic tags

Lub hauv paus ntsiab lus ua haujlwm ntawm RFID thev naus laus zis tsis yog qhov nyuaj: lub cim nkag mus rau hauv qhov chaw sib nqus, tau txais lub xov tooj cua zaus teeb liab los ntawm lub tshuab txiav, thiab xa tawm cov ntaub ntawv cov khoom khaws cia hauv lub nti (PassiveTag) los ntawm kev tsim txiaj ntawm lub zog tau los ntawm qhov induction tam sim no. , lossis nquag xa cov teeb liab ntawm qee zaus (ActiveTag); tus decoder nyeem cov ntaub ntawv thiab txiav txim siab nws, thiab tom qab ntawd xa mus rau hauv cov ntaub ntawv hauv nruab nrab rau kev ua cov ntaub ntawv cuam tshuam.

RFID (xov tooj cua zaus identification) system muaj ob ntu: nyeem ntawv / sau ntawv thiab hluav taws xob transceiver. Tus nyeem ntawv xa tawm electromagnetic pulses los ntawm tus kav hlau txais xov, lub transceiver tau txais cov pulses thiab xa cov ntaub ntawv khaws cia rau tus nyeem ntawv raws li cov lus teb. Nyob rau hauv qhov tseeb, qhov no yog ib tug tsis-hu rau nyeem, sau los yog tshem tawm cov txheej txheem ntawm cov ntaub ntawv nyob rau hauv lub cim xeeb.

Kev hais lus, "smart tag" muaj RFID Circuit Court uas suav nrog RFID nti nrog RFID xov tooj cua zaus thiab ib lub voj voog xov tooj cua nyias, uas tau muab tso rau hauv daim ntawv ua ke nrog cov ntawv yas. Feem ntau, daim ntawv lo yog nplaum rau daim ntawv no, thiab qee cov ntaub ntawv tseem ceeb tuaj yeem luam tawm kom meej rau ntawm daim ntawv lo. Cov cim npe ntse tam sim no feem ntau yog qhov loj ntawm daim npav rho nyiaj, thiab rau cov khoom xa tuaj me me kuj tseem muaj 4.5 x 4.5 cm loj cim npe, nrog rau cov ntawv cim puag ncig nrog lub cheeb ntawm 4.7 cm siv rau hauv CDs thiab DVDs.

Qhov kom zoo dua ntawm transceiver technology piv rau lwm yam ID technologies xws li barcodes los yog sib nqus kab txaij yog lub wireless txuas ntawm tus nyeem ntawv thiab transceiver: lub tsev nyeem / sau tsis xav tau kev sib cuag nrog lub transceiver thiab thiaj li ua tau tag nrho kev koom ua ke rau hauv cov khoom. Qhov no txhais tau hais tias lub transceiver yog tsim rau hnyav ib puag ncig thiab hais tias lub transceiver yog insensitive rau ya raws, av thiab mechanical influences. Yog li, lub transceiver system muaj kev ntseeg siab heev, ceev cov ntaub ntawv tau txais thiab, tiam sis tsis kawg, kev ua haujlwm thiab cov ntawv txuag.

Dab tsi yog technical parameters ntawm daim ntawv lo hluav taws xob?

Cov kev tsis sib haum xeeb ntawm daim ntawv lo hluav taws xob feem ntau yog lub zog xav tau ntawm daim ntawv ua kom lub zog, nyeem / sau nrawm ntawm cov ntaub ntawv daim ntawv lo, tus nqi sib kis ntawm cov ntaub ntawv daim ntawv lo, lub peev xwm ntawm cov ntaub ntawv daim ntawv lo, pob loj ntawm daim ntawv lo, nyeem / sau deb ntawm daim ntawv lo, kev ntseeg siab ntawm daim ntawv lo, kev ua haujlwm zaus ntawm daim ntawv lo thiab tus nqi ntawm daim ntawv lo, thiab lwm yam.

1.Lub zog yuav tsum tau ntawm daim ntawv lo ua kom

Thaum daim ntawv lo hluav taws xob nkag mus rau qhov chaw nyeem-sau ua haujlwm, tau txais cov ntawv nyeem-sau los tawm xov tooj cua zaus teeb liab excitation, daim ntawv lo nkag rau hauv lub xeev ua haujlwm. Daim ntawv lo ua kom lub zog hais txog kev ua kom lub tshuab hluav taws xob daim ntawv lo chip Circuit Court lub zog ntau yam uas xav tau, daim ntawv thov hluav taws xob no thiab cov ntawv nyeem-sau hauv qee qhov kev ncua deb, kev nyeem-sau tuaj yeem muab cov ntawv xov tooj hluav taws xob txaus rau lub zog ntawm lub zog.

2.Qhov nyeem-sau ceev ntawm cov ntaub ntawv sau npe

Kev nyeem ntawv ceev ntawm daim ntawv sau npe suav nrog kev nyeem ntawv nrawm thiab sau nrawm, kev nyeem ntawv nrawm yog hais txog cov ntawv sau hluav taws xob yog nyeem-sau ntawv nrawm, kev sau nrawm yog hais txog cov ntawv sau hluav taws xob cov ntaub ntawv sau nrawm, dav dav cov ntaub ntawv xav tau daim ntawv lo nyeem-sau rau qib millisecond.

3.Lub pob loj ntawm daim ntawv lo

Daim ntawv lo pob loj feem ntau yog nyob ntawm qhov loj ntawm lub kav hlau txais xov thiab lub hwj chim, thiab lwm yam, nyob rau hauv ntau zaus muaj qhov sib txawv ntawm cov pob loj, pob loj me me rau qib millimeter, loj rau qib centimeter.

Yog tias qhov loj ntawm daim ntawv lo hluav taws xob me me, nws muaj ntau yam kev thov, tsis hais cov khoom loj lossis cov khoom me me tuaj yeem teeb tsa. Txawm li cas los xij, kev nrhiav qhov loj me me thiab tsis zoo, yog tias daim ntawv lo hluav taws xob tsim muaj qhov loj, tuaj yeem ua rau qhov loj ntawm lub kav hlau txais xov, yog li tuaj yeem txhim kho cov ntawv nyeem hluav taws xob zoo.

4.Lub peev xwm ntawm daim ntawv lo lus qhia

Lub peev xwm ntawm cov ntaub ntawv daim ntawv lo yog hais txog lub tshuab hluav taws xob daim ntawv lo nqa lub cim xeeb uas muaj rau kev sau cov ntaub ntawv. Cov ntaub ntawv muaj peev xwm loj, thiab daim ntawv lo hluav taws xob yog "pem hauv ntej" hom lossis "backstage" yam ntsig txog.

(1) "Backstage" hom ntawv hluav taws xob

Lub "backstage" hom hluav taws xob daim ntawv lo los ntawm kev nyeem-sau sau cov ntaub ntawv, tom qab ntawd tuaj yeem siv lub network thiab lub khoos phis tawj database kev sib txuas, yog li feem ntau hais lus, tsuav yog lub cim xeeb hluav taws xob muaj ntau tshaj 200 (ntsis), yuav muaj peev xwm ua tau. haum cov khoom code. Yog tias xav tau cov khoom kom ntxaws ntxiv, hom ntawv hluav taws xob no xav tau los ntawm cov ntaub ntawv keeb kwm yav dhau los muab.

(2) "Front desk" hom hluav taws xob daim ntawv lo

Hauv kev xyaum, lub xaib no qee zaum tsis yooj yim rau kev khaws cia hauv online, uas yuav tsum tau nce qhov nco ntawm daim ntawv lo hluav taws xob, xws li nce mus rau ntau txhiab khoom mus rau kaum tawm txhiab ntawm cov khoom, kom cov ntawv sau hluav taws xob tuaj yeem siv nws tus kheej. , tsis tas yuav xyuas cov ntaub ntawv database, daim ntawv lo hluav taws xob no tuaj yeem hu ua "pem hauv ntej" hom ntawv hluav taws xob. Tab sis nyob rau hauv kev xaiv ntawm "foreground" hom hluav taws xob daim ntawv lo yuav tsum xyuam xim rau, feem ntau hais lus loj lub cim xeeb nyeem lub sij hawm ntev, tsuas yog nyob rau hauv cov sij hawm yam tsis tseem ceeb heev, tab sis yuav tsum tau paub cov khoom kom paub meej ntxiv, tsuas yog siv. hom ntawv hluav taws xob no.

5. Qhov sib txawv ntawm daim ntawv lo

Qhov kev nyeem-sau qhov deb ntawm daim ntawv lo yog hais txog kev ua haujlwm deb ntawm daim ntawv lo thiab tus nyeem ntawv. Qhov kev nyeem-sau qhov deb ntawm daim ntawv lo, nyob ze ntawm qib millimeter, deb mus txog 20 meters lossis ntau dua. Tsis tas li ntawd, feem ntau ntawm cov kab ke nyeem qhov deb thiab sau qhov deb yog qhov sib txawv, kev sau nrug yog li 40 feem pua ​​​​rau 80 feem pua ​​​​ntawm kev nyeem ntawv deb.

6. Tus nqi sib kis ntawm cov ntaub ntawv tag

Tus nqi kis tau tus mob ntawm cov ntaub ntawv daim ntawv lo suav nrog ob qho tib si, ntawm ib sab yog daim ntawv lo hluav taws xob los nyeem-sau cov lus tawm tswv yim cov ntaub ntawv kis tau tus mob, ntawm qhov tod tes yog los ntawm kev nyeem-sau sau cov ntaub ntawv tus nqi.

7. Lub sijhawm ua haujlwm ntawm daim ntawv lo

Kev ua haujlwm zaus ntawm daim ntawv lo yog hais txog qhov zaus siv thaum daim ntawv lo ua haujlwm, tuaj yeem ua tau tsawg zaus, siab zaus, ultra-siab zaus thiab microwave.

8. Kev ntseeg tau ntawm daim ntawv lo

Kev ntseeg tau ntawm daim ntawv lo thiab daim ntawv lo ua haujlwm ib puag ncig, qhov loj me, cov khoom siv, zoo, daim ntawv lo thiab nyeem-sau nrug thiab lwm yam. Piv txwv li, thaum nyob rau ntawm txoj siv conveyor, thaum daim ntawv lo tau nthuav tawm thiab nyeem ib tus zuj zus, qhov tseeb ntawm kev nyeem ntawv yog ze rau 100 feem pua. Tab sis ntau yam yuav txo tau qhov kev cia siab ntawm daim ntawv nyeem thiab sau ntawv, ib zaug nyeem cov ntawv nyeem ntau dua, qhov nrawm ntawm lub cim, qhov yuav tshwm sim tsis nyeem lossis nyeem tsis tau.

Nyob rau hauv ib qhov project daim ntawv thov ntawm daim ntawv ntsuam xyuas qhia tau hais tias thaum siv 10000 hluav taws xob tag, 60 hluav taws xob tag nyob rau hauv ib xyoos los ntawm kev puas tsuaj, los ntawm kev puas tsuaj ntawm cov feem ntawm tsawg tshaj li 0.1 feem pua, thiaj li yuav tiv thaiv kev puas tsuaj ntawm cov cim npe hluav taws xob thiab qhov tsis yooj yim uas tshwm sim los ntawm bar code thiab cov cim hluav taws xob nyob rau tib lub sijhawm yog ib qho kev kho kom zoo, yog li koj tuaj yeem luam cov ntawv hluav taws xob sai sai raws li cov ntaub ntawv sau tseg hauv bar code. Tsis tas li ntawd, ib yam khoom los tso ob daim ntawv hluav taws xob hauv rooj plaub kuj yog ib txoj hauv kev, tab sis yuav ua rau tag nrho qhov project raug nqi siab dua.
