Dab tsi ua ibRFID nyeem ntawvUa tiag tiag?

Nov yog qee yam tsis muaj leej twg qhia koj ntawm RFID cov rooj sib tham: ib nrab ntawm cov neeg nyeem tau teeb tsa hauv cov tsev khaws khoom tam sim no ua tau zoo dua li cov tshuab barcode lawv hloov. Tsis yog vim tias thev naus laus zis tsis ua haujlwm-nws ua-tab sis vim cov tuam txhab yuav cov neeg nyeem tib yam lawv yuav lwm yam khoom siv, thiab qhov ntawd yog qhov teeb meem nyob ntawd.

Kuv tau siv kaum ob xyoos saib cov lag luam hlawv los ntawm RFID pob nyiaj siv. Lub RAIN Alliance tuaj yeem khav txog 52.8 billion daim ntawv xa tawm xyoo tas los, tab sis qhov uas lawv tsis tshaj tawm yog pes tsawg ntawm cov ntawv no tsis tau nyeem kom raug, lossis tau nyeem nees nkaum zaug thaum lawv yuav tsum tau nyeem ib zaug, lossis tsoo tag nrho cov khoom lag luam vim tias ib tus neeg spec'd tus nyeem ntawv tsis raug rau cov hlau - hnyav ib puag ncig.

Yog li cia peb tham txog dab tsi RFID cov neeg nyeem ua tau tiag tiag, ua li cas tawg, thiab yuav ua li cas kom tsis txhob nkim rau 6 daim duab pom.

Tus nyeem ntawv txoj hauj lwm (Simple dua li cov neeg muag khoom ua kom nws suab)

Tshem tawm qhov kev lag luam thiab tus nyeem ntawv ua peb yam: nws qw rau hauv chav tsev, mloog cov lus teb, thiab txiav txim siab dab tsi rov qab los. Qhov ntawd yog nws. Lub complexity nyob rau hauvua li casnws ua tej yam ntawd.

Teb ceev:Tus nyeem ntawv RFID yog cov khoom siv uas tsim cov xov tooj cua, xa cov lus txib rau RFID cim npe, tau txais cov lus teb tag, lim cov ntawv luam tawm, thiab xa cov ntaub ntawv siv tau rau software. Hauv kev ua haujlwm, tus nyeem ntawv tsis yog "scanner" nkaus xwb; nws yog RF tswj taw tes uas txiav txim siab thaum twg, qhov twg, thiab yuav ua li cas tag cov ntaub ntawv dhau los ua kev lag luam.

RFID Reader vs Tag vs. Kav hlau txais xov: Dab tsi Txhua Qhov Ua Tau

Cov neeg tshawb nrhiav feem ntau sib xyaw cov nyeem ntawv, cim npe, thiab tus kav hlau txais xov. Lub cim muaj tus cim. Lub kav hlau txais xov tsim cov cheeb tsam nyeem. Tus nyeem ntawv tswj hwm qhov kev sib tham, ua kom muaj lub cim tsis zoo thaum xav tau, txiav txim siab cov lus teb, thiab xa cov ntaub ntawv huv mus rau lub tswv tsev. Rau kev piav qhia tob dua ntawm huab cua- sib pauv hloov pauv, saib phau ntawv qhia txog qhov noYuav ua li cas RFID tags sib txuas lus nrog cov neeg nyeem.

Qhov system	Txoj hauj lwm tseem ceeb	Dab tsi tuaj yeem ua yuam kev
RFID tag	Khaws EPC, UID, lossis cov neeg siv cov ntaub ntawv uas txheeb xyuas cov khoom.	Chip yuam kev, tsis muaj zog kav hlau txais xov tsim, tsis zoo tso, hlau detuning, kua nqus.
RFID kav hlau txais xov	Tsim qhov chaw nyeem tiag tiag thiab txiav txim siab polarization, kab dav dav, thiab cov duab npog.	Tshaj - nyeem ntawv, qhov muag tsis pom kev, lub kaum sab xis tsis zoo, nce tsis ncaj ncees lawm, tsis ntev cable poob.
RFID nyeem ntawv	Tswj fais fab, zaus hopping lossis channel siv, tiv thaiv -kev sib tsoo, tag cov lus txib, lim, thiab cov ntaub ntawv tso tawm.	Tsawg tus neeg txais kev hnov mob, tsis zoo los tiv thaiv- kev sib tsoo, kev txhawb nqa API tsis muaj zog, tsis txaus rau kev ntsuas ib puag ncig.

Thaum koj siv zog rau tus nyeem ntawv, nws tsim lub zog RF ntawm txhua qhov zaus koj siv -125 kHz rau cov khoom qub qub, 13.56 MHz yog tias koj tab tom ua NFC lossis lub tsev qiv ntawv, lossis 860-960 MHz rau UHF systems uas txhua tus neeg siv tam sim no. Lub zog no radiates los ntawm tus kav hlau txais xov mus rau hauv cov neeg muag khoom hu ua "nyeem cheeb tsam" tab sis qhov tseeb zoo li qhov pom tsis pom ntawm lub tshuab hluav taws xob uas hloov cov duab raws li cov hlau nyob ze, pob zeb ntom ntom, thiab seb ib tug neeg nres lub forklift hauv qhov chaw tsis ncaj ncees lawm.

Rau cov ntawv cim passive (uas yog 95% ntawm kev xa tawm), cov teeb liab kis tau ob npaug. Nws powers tag lub nti THIAB nqa cov lus txib nug. Lub cim npe sawv, hloov kho lub teeb liab nrog nws cov ntaub ntawv, thiab thaws rov qab rau tus nyeem ntawv. Qhov teeb liab backscatter no rov qab los ntawm lub zog tsis txaus ntseeg - peb tab tom tham 60-70 dB hauv qab uas tau kis, uas txhais tau tias yog tus nyeem ntawv qw ntawm 1 watt, lub cim ntxhib rov qab ntawm 0.0000001 watts.

Tus nyeem ntawv txais yuav tsum xaiv qhov ntxhi ntawm nws tus kheej qw. Qhov no yog vim li cas cov neeg nyeem pheej yig pheej yig - lawv skimp ntawm qhov tau txais circuitry, thiab mam li nco dheev koj tshaj tawm 10-meter nyeem ntau dhau los ua 3 meters nrog cov khoom tiag tiag ntawm cov txee tiag.

Kev sib pauv tag nrho yuav siv sijhawm 3-20 milliseconds rau ib lub cim, nyob ntawm seb koj cov ntaub ntawv ntau npaum li cas thiab cov txheej txheem twg koj tab tom khiav. Ceev txaus uas nws xav tau tam sim ntawd, qeeb txaus tias yog tias koj tab tom sim nyeem 500 lub cim ya yav dhau los ntawm lub conveyor ntawm 2 meters ib ob, koj yuav tsum tau ua lej.

The Reader's Job (Simpler Than Vendors Make It Sound)

Yog vim li cas koj nyeem Range Specs yog dag

Txhua lub lawj muag RFID qhia tib daim duab: tus nyeem ntawv txuas nrog lub kav hlau txais xov, nrog lub zoo meej arc qhia nyeem ntau yam. "Txog 12 meters!" lawv hais. Thiab technically, lawv tsis dag. Nyob rau hauv lub RF anechoic chamber, nrog ib lub cim ntawm kev taw qhia zoo meej, ntawm qhov zoo tshaj plaws kub, tsis muaj kev cuam tshuam, mounted rau ua npuas ncauj, koj yuav ntaus 12 meters.

Hauv koj lub tsev khaws khoom? Koj yuav tau txais 4-6 meters nyob rau ib hnub zoo.

Nov yog dab tsi noj koj qhov ntau:

Tag orientation tua koj ua ntej.

UHF RFID yog polarization-sensitive. Yog tias koj lub cim npe kav hlau txais xov yog perpendicular rau tus nyeem ntawv tus kav hlau txais xov polarization, koj qhov kev nyeem ntawv poob qis los ntawm 90%. Qhov no yog vim li cas qhov kev teeb tsa portal xav tau plaub lub kav hlau txais xov yam tsawg kawg nkaus - koj tab tom sim npog txhua txoj hauv kev uas lub thawv tuaj yeem hla ntawm lub qhov rooj. Kuv saib lub chaw faib khoom siv $80K rau cov nyeem thiab cov kav hlau txais xov ua ntej ib tus neeg paub tias lawv lub thawv corrugated tau taw qhia 90 degrees los ntawm qhov kev sib koom ua ke xav tau. Lawv tau mus ntxiv ob lub kav hlau txais xov ntxiv thiab tseem tsis tau ntaus lawv lub hom phiaj nyeem ntawv.

Hlau nyob txhua qhov chaw thiab nws ntxub koj.

Muab ib daim ntawv RFID rau ntawm cov hlau saum npoo thiab cov hlau luv tawm ntawm daim npav tus kav hlau txais xov. Tag mus tsaus. "Tab sis peb yuav ntawm -hlau tag!" Tseeb, thiab cov no ua haujlwm zoo hauv chav kuaj. Hauv daim teb, koj pom tias "on-hlau" txhais tau tias "flat tiv thaiv hlau" thiab koj cov ntawv cim tau tiag tiag ntawm cov thawv uas qee zaum tawm tsam hlau, qee zaum tsis yog, qee zaum ntawm cov ces kaum. Tam sim no koj tab tom cuam tshuam nrog ntau qhov kev xav txog qhov twg lub teeb liab tawm ntawm peb qhov chaw ua ntej tsoo lub cim, thiab koj qhov 8-meter nyeem ntau dhau los ua 8 centimeters. Los yog 12 meters. Los yog nws nyeem tib daim ntawv plaub caug zaug vim hais tias lub teeb liab yog bouncing ib ncig zoo li pinball.

Dej absorbs RF ntawm 900 MHz

zoo li koj yuav tsis ntseeg. Pallets ntawm lub raj mis dej? Npau suav phem. Puas muaj dab tsi uas muaj dej ntau? Tsis nco qab nyeem tas li. Muaj ib qho laj thawj cov khw muag khaub ncaws nyiam RFID-cov ntaub ntawv nyeem huv. Tab sis sim taug qab rooj plaub ntawm cov kaus poom kua zaub thiab koj yuav nkag siab tias vim li cas cov zaub mov faib tau qeeb los txais yuav.

Cable khiav tseem ceeb tshaj li leej twg lees.

Qhov 10-meter cable khiav ntawm koj tus nyeem ntawv mus rau koj lub kav hlau txais xov? Koj nyuam qhuav poob 5 dB, uas txhais tau li ib nrab ntawm koj qhov kev nyeem ntawv. Siv cov cable pheej yig thiab koj poob ntau dua. Kuv tau kuaj pom "cov neeg nyeem tsis tau" uas yog cov neeg nyeem zoo kawg nkaus txuas nrog kev sib txuas lus hauv qab daus uas tau poob 8-9 dB. Hloov $ 40 ntawm cable, mam li nco dheev lub kaw lus ua haujlwm.

Qhov Kev Xaiv Zaus Tsis muaj leej twg piav kom raug

Koj tau txais peb pawg los xaiv los ntawm, thiab tsob ntoo txiav txim siab yooj yim dua li cov neeg muag khoom ua piv txwv:

125 kHz (LF)

yog tias koj tab tom sau tsiaj, xav tau nyeem hauv dej, lossis muaj cov cai tswj hwm uas yuam koj ntawm no. Qhov ntev ntawm cov ntaub ntawv yog 10 cm. Hloov cov ntaub ntawv yog qeeb. Tag nqi $2-5 txhua. Yuav luag tsis muaj leej twg xaiv qhov no ntxiv lawm tshwj tsis yog lawv yuav tsum tau.

13.56 MHz (HF)

yog tias koj tab tom them nyiaj, NFC kev sib koom ua ke hauv xov tooj, lub tsev qiv ntawv, lossis kev tshuaj xyuas tshuaj uas koj xav tau tag- qib kev ruaj ntseg. Nyeem ntau yog nyob rau hauv ib 'meter'. Cov ntawv yog pheej yig ($ 0.10-0.50). ISO 15693 tus qauv yeej ua haujlwm thoob plaws cov neeg muag khoom, uas tsis tshua muaj nyob hauv RFID ntiaj teb. Cov qhab no ntaus siab tshaj nws qhov hnyav rau cov ntawv thov tshwj xeeb tab sis muab cov saw hlau cov neeg feem ntau hla nws vim qhov kev nyeem ntau dhau kev txwv.

860-960 MHz (UHF)

rau txhua yam. Qhov no yog qhov ntim qhov twg, qhov twg qhov kev tsim kho tshiab yog, qhov teeb meem nyob qhov twg. Kev nyeem ntawv tuaj yeem ntaus 10+ meters nrog cov cuab yeej tsim nyog thiab cov xwm txheej zoo. Tag nqi $0.05-0.15 hauv ntim. Koj tuaj yeem nyeem ntau pua lub cim ib pliag. But you pay for that performance with complexity-metal interference, liquid absorption, regulatory fragmentation across regions, and dense reader environments that require actual RF engineering to get right.

Cov txheej txheem kev cai yog messier tshaj nws yuav tsum yog. North America tau txais 902-928 MHz nrog zaus hopping, uas yog huv si. Teb chaws Europe tau daig nrog 865-868 MHz thiab yuav tsum tau mloog- ua ntej - tham cov txheej txheem uas tso koj cov peev txheej. Asia yog fragmented los ntawm lub teb chaws. Yog tias koj tab tom xa mus thoob ntiaj teb, koj tuaj yeem yuav cov neeg nyeem tshwj xeeb hauv cheeb tsam lossis koj yuav cov neeg nyeem uas txhawb nqa ntau pawg thiab lees tias lawv raug nqi ntau dua thiab ua haujlwm tsis zoo dua li thaj tsam-optimized units.

Yam twg RFID Reader Frequency Fits Qhov Project?

Kev xaiv zaus yuav tsum pib nrog kev lag luam ua haujlwm, tsis yog phau ntawv teev npe. Ib txoj haujlwm ua tsiaj txhu, lub tsev so daim npav, chaw ua haujlwm-hauv- chaw nres tsheb, thiab chaw nres nkoj- qhov rooj qhov rooj yuav siv tau RFID, tab sis lawv tsis xav tau tib tus nyeem ntawv. Kev xa tawm UHF thoob ntiaj teb feem ntau yog tsim los ntawm EPC Gen2 / ISO 18000-6C style kev sib txuas lus; GS1 piav txog nwsEPC Gen2 huab cua interface raws tu qauvraws li lub cev thiab kev xav tau rau UHF RFID systems.

Daim ntawv yuav khoom:Rau cov haujlwm thoob ntiaj teb UHF, tsis txhob xav tias ib tus nyeem ntawv teeb tsa ua haujlwm txhua qhov chaw. RAIN RFID qhov kev taw qhia taug qab cov kev faib cheeb tsam hauv cheeb tsam hauv 860-960 MHz band, thiab cov kev cai no cuam tshuam rau kev nyeem ntawv teeb tsa, kav hlau txais xov fais fab, thiab kev ua tiav. Saib covRAIN RFID system tsim cov txheej txheemua ntej standardizing tus qauv nyeem ntawv thoob ntiaj teb.

Dab tsi Tiag Tiag (Cov Lus Qhia Los Ntawm Kev Ua Tsis Taus)

Feem ntau RFID tsis ua haujlwm tsis yog kev ua haujlwm thev naus laus zis. Lawv yog cov kev cia siab tsis sib haum, kev npaj tsis zoo, lossis cov neeg koom ua ke uas spec'd los ntawm phau ntawv teev npe yam tsis tau mus xyuas lub xaib. Nov yog qhov kuv pheej pom:

Portal kev teeb tsa uas nyeem txhua yam tshwj tsis yog qhov lawv yuav tsum tau nyeem.

Lub tuam txhab teeb tsa lub qhov rooj qhov rooj nkag los nyeem cov khoom xa tawm sab nraud. Tus nyeem ntawv ua haujlwm zoo- nyeem txhua yam khoom tagged hauv lub tsev khaws khoom hauv 15 ko taw ntawm lub qhov rooj, suav nrog cov khoom uas tsis thauj khoom. Cov khoom lag luam poob vim nws xav tias txhua yam tsuas yog sab laug. Qhov teeb meem? Lawv ua kom zoo rau kev nyeem ntau tab sis tsis nco qab txog kev nyeem cheeb tsamciam teb. Koj xav tau lub zog txaus los nyeem cov ntawv hla dhau ntawm lub portal, tab sis tsis yog ntau npaum li koj nyeem mus rau thaj chaw uas nyob ib sab. Qhov no yuav tsum xaiv tus kav hlau txais xov, qhov chaw, lub zog tu, thiab qee zaum RF- nqus cov khoom los tsim cov cheeb tsam uas tau hais tseg. Nws tsis nyuaj tab sis nws xav tau ib tus neeg uas nkag siab cov qauv hauv teb, tsis yog ib tus neeg uas tuaj yeem xa cov kav hlau txais xov.

"Peb mam li txheeb xyuas qhov chaw tso npe tom qab" cov haujlwm.

Tag kev tso kawm yog tag nrho cov kev ua si. Cov khw muag khaub ncaws hnav cov ntawv lo ntawm cov cim dai lossis xaws rau hauv cov nyiaj seam - ua haujlwm zoo kawg nkaus. Electronics manufacturers sim tag cov khoom nyob rau hauv anti- hnab zoo li qub- tsis ua hauj lwm vim hais tias lub hnab metalized shields tag. Ib tus neeg muag khoom tsheb uas kuv tau ua haujlwm nrog yog tagging cov thawv rov qab. Lawv dai tag rau ntawm phab ntsa. Cov thawv ntim khoom. Hlau thawv phab ntsa thaiv cov cim npe hauv nruab nrab ntawm pawg. Kev nyeem ntawv yog 40%. Peb tau txav cov cim npe mus rau lub thawv daim di ncauj qhov chaw uas lawv tsis muaj kev tiv thaiv- nyeem tus nqi mus rau 97%. Ob nti sib txawv hauv kev tso kawm, 2.5x kev txhim kho hauv kev ua haujlwm.

Cov neeg nyeem tsis pom zoo txuag nyiaj ua ntej, raug nqi nyiaj mus ib txhis.

Koj tuaj yeem yuav tus nyeem ntawv UHF rau $ 400 lossis $ 4,000. Tus nqi pheej yig muaj -70 dBm receiver rhiab heev. Tus nqi kim muaj -80 dBm. Qhov sib txawv ntawm 10 dB yog 3x qhov sib txawv hauv kev nyeem ntau, uas txhais tau hais tias tus nyeem ntawv pheej yig xav tau 3x ntau tus kav hlau txais xov los npog tib thaj chaw. Tsuas yog cov kav hlau txais xov cov chaw nres nkoj raug nqi nyiaj, yog li tam sim no koj xav tau cov neeg nyeem ntau dua, kev sib txuas lus ntau dua, ntau cov txheej txheem. TCO ntawm cov neeg nyeem pheej yig feem ntau yog siab dua, lawv tsuas yog zais nws hauv lub sijhawm xa tawm es tsis txhob muab tso rau hauv qhov kev tsocai.

Zero cuam tshuam kuaj kom txog thaum nws lig dhau lawm.

UHF RFID ua haujlwm hauv ISM band nrog Wi-Fi, Bluetooth, xov tooj tsis muaj zog, thiab microwave ncu. Kuv tau kuaj pom cov teeb meem nyeem tau tshwm sim los ntawm Wi-Fi nkag point 30 ko taw deb, muaj lub suab nrov nrov nkag rau hauv tus nyeem ntawv tau txais txoj hauv kev, thiab-Kuv tus kheej nyiam- lub tsev xov tooj ntawm tes kav hlau txais xov cuam tshuam nrog kev teeb tsa kev nyeem ntawv ru tsev. Cov lus teb yog RF qhov chaw tshawb fawb ua ntej koj yuav khoom, tsis yog tom qab koj tau teeb tsa 50 tus nyeem ntawv uas tsis ua haujlwm tas li.

Specifications That matters (Thiab tus lej lag luam uas tsis yog)

Thaum koj tab tom sib piv cov nyeem, ntawm no yog dab tsi tiag tiag saib:

Tus txais rhiab heev yog huab tais.

Tus lej no, feem ntau tau hais hauv dBm, qhia koj tias qhov tsis muaj zog npaum li cas rau tus nyeem ntawv tuaj yeem txiav txim siab . -70 dBm yog qhov pib rau cov neeg siv khoom -qib units. -75 dBm yog qhov tsim nyog . -80 dBm lossis zoo dua yog qhov koj xav tau rau cov ntawv thov. Txhua 3 dB ntawm rhiab heev roughs doubles koj nyeem ntau los yog cia koj nyeem los ntawm cov ntaub ntawv tougher. Cov spec no feem ntau yog faus rau hauv cov ntaub ntawv vim nws tsis tau ntxim hlub, tab sis nws txiav txim siab seb koj lub cev ua haujlwm lossis tsis ua haujlwm.

Ua hwj huam vs. zoo radiated zog

Qhov teeb meem ntau dua hauv Tebchaws Europe dua li North America vim tias ETSI cov cai txwv ERP rau 2W thaum FCC txwv tau ua lub zog rau 1W. Cov neeg tsim khoom ua si qhov no nrog siab -tau txais kav hlau txais xov, uas yog qhov zoo tshwj tsis yog siab -tau txais cov kav hlau txais xov muaj qhov nqaim dav dav, uas txhais tau tias ntau lub kav hlau txais xov los npog koj cheeb tsam, uas txhais tau tias tus nqi siab dua. Nyeem cov specs kom zoo thiab xyuas kom tseeb tias koj tab tom sib piv cov teeb tsa sib npaug.

Kav hlau txais xov ports

txiav txim siab yooj. Ob -port nyeem ntawv yog pheej yig tab sis txwv koj cov kev xaiv kev pab them nqi. Plaub qhov chaw nres nkoj yog tus qauv rau kev teeb tsa ruaj khov. Yim qhov chaw nres nkoj muaj tab sis ntxiv tus nqi thiab qhov nyuaj uas koj tsis tshua xav tau. Tseem ceeb dua: tus nyeem ntawv tuaj yeem tswj hwm tus kav hlau txais xov chaw nres nkoj (lub sijhawm, lub zog, lub sijhawm) lossis nws tsuas yog puag ncig -robin los ntawm lawv? Kev tswj hwm ywj pheej ua rau muaj kev tiv thaiv zoo dua - kev sib tsoo kev ua haujlwm thiab kev sib cais ntawm cheeb tsam.

Anti-kev sib tsoo raws tu qauv txhawb nqa

cais cov kws tshaj lij thiab cov neeg siv khoom kho vajtse. EPC Gen2 (ISO 18000-6C) raws tu qauv yog lub hauv paus- yog tus nyeem ntawv tsis txhawb qhov no, tsis txhob yuav nws. Gen2v2 ntxiv cov yam ntxwv zoo li cov lus txib tsis tuaj yeem thiab cov ntawv pov thawj uas tseem ceeb rau cov ntawv thov tshwj xeeb tab sis tsis yog qhov yuav tsum tau muaj thoob ntiaj teb. Kev siv Q-algorithm txiav txim siab seb tus nyeem ntawv ua haujlwm zoo npaum li cas rau cov neeg tag. Static Q teeb tsa ua haujlwm yog tias koj muaj qhov ntsuas pom qhov ntom ntom. Kev hloov pauv Dynamic Q yog qhov tseem ceeb yog tias tag cov pej xeem sib txawv heev.

Kev ntsuas ib puag ncig

dhuav txog thaum dej nkag rau hauv koj tus nyeem ntawv $3,000. IP65 yog qhov tsawg kawg nkaus rau cov khoom lag luam ib puag ncig. IP67 yog tias muaj kev nyab xeeb los yog huab cua raug. Kev khiav hauj lwm kub specs tseem ceeb yog tias koj tab tom xa mus rau hauv cov chaw khaws khoom tsis muaj xwm txheej-Kuv tau pom lub caij ntuj sov lub ru tsev kub kub txog 140℃F hauv Texas cov chaw faib khoom. Qhov ntawd tseem ceeb.

API thiab kev xaiv kev koom ua ke

txiav txim siab seb qhov kev xa tawm yuav siv li cas ob lub lis piam lossis rau lub hlis. Cov neeg nyeem zoo muab REST APIs huv si, SDKs rau lub platform loj, thiab cov ntaub ntawv tsim nyog nrog cov qauv ua haujlwm. Cov neeg nyeem tsis zoo muab rau koj 200-nplooj PDF sau los ntawm cov kws ua haujlwm uas tsis tau koom ua ke. LLRP raws tu qauv yog tus qauv tab sis kev siv LLRP los ntawm kos yog mob. Yog tias tus neeg muag khoom cov lus teb rau cov lus nug kev koom ua ke yog "tsuas yog siv LLRP," uas yog tus chij liab.

Los ntawm Tag Nyeem Rau Kev Ua Lag Luam: Cov Ntaub Ntawv Ua Haujlwm Cov Neeg Yuav Tsis Nco

Kev ua tiav RFID nyeem ntawv xa mus tsis tas thaum tus nyeem ntawv pom lub cim. Raw nyeem yog nrov. Tib EPC yuav raug ntes tau ntau zaus los ntawm ob peb lub kav hlau txais xov, lossis nws yuav raug nyeem los ntawm thaj chaw nyob sib ze. Tus nyeem ntawv lossis cov khoom nruab nrab yuav tsum tau hloov cov ntaub ntawv nyoos mus rau hauv cov xwm txheej tseem ceeb xws li "cov ntaub ntawv nkag mus rau hauv qhov rooj 3," "cov khoom muaj nqis tau pom nyob rau hauv txoj kab B," lossis "lub thawv rov qab mus rau qhov chaw nres tsheb."

Kev ntes:tus nyeem ntawv sau cov lus teb los ntawm ib lossis ntau lub kav hlau txais xov.
Lim:duplicate, tsis muaj zog, los yog tawm - ntawm - cheeb tsam nyeem raug tshem tawm raws li lub sij hawm, kav hlau txais xov, RSSI, los yog txoj cai kev lag luam.
Koom nrog:daim npav ID yog txuam nrog SKU, cov ntaub ntawv khoom vaj khoom tsev, thawv ID, tus neeg mob ID, lossis daim ntawv xaj ua haujlwm.
Trigger:lub kaw lus hloov kho cov khoom muag, qhib lub qhov rooj, txheeb xyuas cov khoom xa tuaj, ceeb toom cov neeg ua haujlwm, lossis sau cov ntaub ntawv rov qab rau lub cim.

Qhov no yog qhov uas pheej yig xa tawm feem ntau ua tsis tiav. Ib tus nyeem ntawv tuaj yeem ua "kev nyeem ntawv" thaum ERP, WMS, nkag mus rau qhov system, lossis mobile app tau txais cov xwm txheej phem. Rau cov haujlwm uas xav tau qhov tseeb rov ua dua, tsim software kev sib koom ua ke thiab zam kev tuav mus rau hauv tus tsav, tsis yog tom qab kev teeb tsa kho vajtse.

Hom Nyeem Ntawv Rau Cov Ntawv Thov tiag

Fixed readers for portal and overhead applications

Tsau nyeem ntawv rau cov ntawv thov portal thiab nyiaj siv ua haujlwm

yuav tsum tau ua ntau pua cov cim npe ib ob nrog cov ntawv nyeem zoo heev.
