Dab tsi yog Cov Txheej Txheem ntawm RFID System?

Kev sib xyaw ntawm RFID System

 

Ib tug raug RFID system feem ntau yog tsim los ntawm plaub qhov chaw: nyeem ntawv, hluav taws xob tag, RFID middleware, thiab daim ntawv thov system software. Feem ntau, cov khoom nruab nrab thiab daim ntawv thov txheej txheem software tau sau ua ke hu ua daim ntawv thov system, raws li qhia hauv daim duab 1-2.

 

Hardware Components

 

Nyeem ntawv

 

 

1) Xov tooj cua zaus InterfaceLub luag haujlwm tseem ceeb ntawm lub xov tooj cua zaus interface module yog raws li hauv qab no:

(1) Tsim siab - zaus kis tau tus mob rauqhibhluav taws xob tag thiab muab lub zog rau nws.

(2) Hloov kholub teeb liab kis tau tus mob kis tau cov ntaub ntawv mus rau lub electronic tag.

(3) Txais thiab demodulatexov tooj cua zaus teeb liab los ntawm hluav taws xob tag.

Lub xov tooj cua zaus interface muaj ob lub teeb liab sib cais, siv raws li cov ntaub ntawv xa mus rau ob qho kev qhia, mus rau thiab los ntawm cov ntawv hluav taws xob thiab tus nyeem ntawv. Cov ntaub ntawv xa mus rau lub cim hluav taws xob yog xa mus los ntawm lub chaw xa xov hluav taws xob, thiab cov ntaub ntawv los ntawm cov khoom siv hluav taws xob tau txais los ntawm lub receiver ceg channel.

 

2) Logic Control UnitLub logic tswj chav tseem hu ua tus nyeem / sau module, thiab nws cov haujlwm tseem ceeb yog raws li hauv qab no:

(1) Sib txuas lusnrog rau daim ntawv thov system thiab ua cov lus qhia xa los ntawm daim ntawv thov system.

(2) Tswjcov txheej txheem kev sib txuas lus ntawm tus nyeem ntawv thiab lub cim hluav taws xob.

(3) Encoding thiab decodingntawm cov cim.

(4) Encryption thiab decryptionntawm cov ntaub ntawv kis ntawm tus nyeem ntawv thiab tag.

(5) Ua haujlwmanti-kev sib tsoo algorithm.

(6) Txheeb xyuastus neeg nyeem ntawv thiab tag.

 

3) Kav hlau txais xovLub kav hlau txais xov yog ib qho khoom siv uas hloov tau cov hluav taws xob tsis zoo rau hauv cov teeb liab tam sim no, lossis hloov cov teeb liab tam sim no mus rau hauv hluav taws xob nthwv dej rau kev sib kis. Nyob rau hauv RFID system, tus nyeem ntawv yuav tsum xa xov tooj cua zaus zog los ntawm tus kav hlau txais xov los tsim ib qho chaw electromagnetic. Electromagnetic teb yog siv los txheeb xyuas cov cim hluav taws xob. Yog li ntawd, qhov ntau ntawm electromagnetic teb tsim los ntawm tus kav hlau txais xov ntawm tus nyeem ntawv yog qhov chaw nyeem tau ntawm tus nyeem ntawv.

 

Electronic Tag

 

Covelectronic tag(electronic tag), tseem hu uantse daim ntawv lo(smart label), hais txog micro-cov cim me me uas tsim los ntawm ib qhoIC chipthiab awireless kev sib txuas lus kav hlau txais xov. Nws tsim - hauv xov tooj cua zaus kav hlau txais xov yog siv los sib txuas lus nrog tus nyeem ntawv. Thaum lub kaw lus ua haujlwm, tus nyeem ntawv xa tawm cov lus nug (lub zog) teeb liab, thiab lub cim (passive) rectifies ib feem ntawm cov lus nug tau txais (lub zog) teeb liab rau hauv DC fais fab mov rau lub voj voog hauv lub tshuab hluav taws xob ua haujlwm; lwm qhov ntawm lub zog teeb liab yog hloov kho los ntawm cov ntaub ntawv cov ntaub ntawv khaws cia hauv cov ntawv hluav taws xob thiab xa rov qab rau tus nyeem ntawv. Daim npav hluav taws xob yog cov ntaub ntawv muaj tseeb ntawm Xov Tooj Cua Kev Qhia Txog Kev Ntsuas, thiab nws daim ntawv thov nws txawv raws li cov xwm txheej sib txawv. Piv txwv li, nyob rau hauv lub tshav pob ntawm cov tsiaj nrhiav thiab tracing, nws yog hu ua tsiaj tag, tsiaj tracing tag, los yog electronic dog tag; nyob rau hauv qhov chaw uas tsis yog- nres kev sau xov tooj lossis kev tswj xyuas lub tsheb, nws yog hu ua daim npav IC daim npav ntev - deb, ntev - tsheb npav, lossis daim ntawv tsav tsheb hluav taws xob; hauv kev tswj xyuas kev nkag mus, nws yog hu ua daim npav nkag lossis tag nrho -hauv-ib daim npav. Cov qauv sab hauv ntawm daim npav hluav taws xob tau pom hauv daim duab 1-4.

 

 

Cov haujlwm ntawm cov modules hauv lub tshuab hluav taws xob tau piav qhia raws li hauv qab no:

(1) Kav hlau txais xov:Siv rautxaislub teeb liab xa los ntawm tus nyeem ntawv thiab xa cov ntaub ntawv thov rov qab mus rau tus nyeem ntawv.

(2) Qhov Voltage Regulator:Hloov cov xov tooj cua zaus xov tooj cua xa los ntawm tus nyeem ntawv mus rau hauv DC fais fab mov, khaws lub zog los ntawm lub capacitor loj, thiab tom qab ntawd muab lub zog ruaj khov los ntawm qhov hluav taws xob stabilizing circuit.

(3) Modulator:Cov ntaub ntawv xa los ntawm lub logic tswj Circuit Court yog modulated los ntawm lub modulation circuit thiab ces loaded mus rau lub kav hlau txais xov thiab xa mus rau tus nyeem ntawv. (4)Demodulator:Tshem tawm cov cab kuj nthwv dej kom rho tawm qhov tseeb modulated teeb liab.

(5) Logic Control Unit:Siv rautxiav txim siablub teeb liab xa los ntawm tus nyeem ntawv thiab xa cov ntaub ntawv rov qab rau tus nyeem ntawv raws li nws xav tau.

(6) Chav tsev cia khoom:suav nrogEEPROM thiab ROM, ua qhov chaw rau kev ua haujlwm thiab khaws cov ntaub ntawv txheeb xyuas.

 

Software Components

 

Middleware

 

Middlewareyog ib qho kev ywj pheej software lossis kev pabcuam. Distributed application software siv cov software no los qhia cov peev txheej ntawm cov thev naus laus zis sib txawv. Middleware yog nyob rau saum toj ntawm lub operating system ntawm cov neeg siv khoom thiab cov neeg rau zaub mov, tswj xyuas cov peev txheej thiab kev sib txuas lus hauv network. Raws li pom nyob rau hauv daim duab 1-5, RFID middleware plays lub luag hauj lwm nruab nrab ntawm cov hluav taws xob tag thiab daim ntawv thov kev pab cuam. Daim ntawv thov kawg siv cov txheej txheem dav davApplication Programming Interfaces (API)muab los ntawm cov khoom nruab nrab los nyeem cov ntaub ntawv hluav taws xob tag. Ua li no, txawm tias cov ntaub ntawv software khaws cov ntaub ntawv hluav taws xob lossis rov qab -kawg daim ntawv thov raug ntxiv lossis hloov los ntawm lwm cov software, lossis yog tias hom RFID nyeem ntawv nce, daim ntawv thov kawg tseem tuaj yeem ua tiav yam tsis muaj kev hloov kho, daws teeb meem kev tu vaj tse complexity ntawm ntau - mus rau -ntau yam kev sib txuas.

 

 

RFID Middleware feem ntau suav nrog cov hauv qab no4muaj nuj nqi:

 

1) Kev Sib Koom Tes thiab Kev Tswj Xyuas Nyeem Ntawv

Xaus- cov neeg siv tuaj yeem teeb tsa, saib xyuas, thiab xa cov lus txib mus rau tus nyeem ntawv los ntawm RFID nruab nrab software interface. Piv txwv li, kawg - cov neeg siv tuaj yeem teeb tsa tus nyeem ntawv kom kaw cia thaum muaj kev sib tsoo ntau zaus. Qee cov neeg tsim khoom nruab nrab ntawm RFID kuj tseem muab cov ntsaws- thiab- ua si ua haujlwm rau cov neeg nyeem, yog li kawg - cov neeg siv tsis xav tau cov lej program ntxiv thaum ntxiv hom tshiab nyeem.

 

2) Cov ntaub ntawv lim thiab ua haujlwm

Thaum cov ntaub ntawv xa tawm tsis raug tshwm sim lossis cov ntaub ntawv tsis raug tsim tawm, RFID cov khoom nruab nrab tuaj yeem kho qhov tsis raug thiab lim tawm cov ntaub ntawv rov ua dua los ntawm qee qhov algorithm. RFID middleware tuaj yeem tiv thaiv cov neeg nyeem sib txawv los ntawm kev sib tsoo thaum nyeem tib lub cim hluav taws xob, ua kom cov ntaub ntawv raug siab dua li qib nyeem ntawv.

 

3) Data Routing thiab kev koom ua ke

RFID middleware tuaj yeem txiav txim siab seb daim ntawv thov twg cov ntaub ntawv khaws tseg yuav tsum raug xa mus rau. RFID middleware tuaj yeem ua ke nrog cov software lag luam uas twb muaj lawm xws liEnterprise Resource Planning (ERP), Customer Relationship Management (CRM), thiabWarehouse Management System (WMS), muab cov ntaub ntawv routing thiab kev koom ua ke. Tib lub sijhawm, cov khoom nruab nrab kuj tuaj yeem khaws cov ntaub ntawv thiab xa mus rau ntau daim ntawv thov hauv cov khoom siv.

 

4) Kev Tswj Xyuas Txheej Txheem

Hauv kev tswj cov txheej txheem, RFID middleware saib xyuas cov ntaub ntawv ua haujlwm raws li kev cai thiab ua rau cov xwm txheej rau cov neeg siv khoom. Piv txwv li, hauv kev tswj cov khoom lag luam, cov khoom nruab nrab tuaj yeem teeb tsa los saib xyuas cov khoom lag luam kom muaj nuj nqis, thiab thaum cov khoom lag luam qib qis qis dua cov txheej txheem, RFID cov khoom nruab nrab yuav ua rau muaj kev tshwm sim ceeb toom rau cov ntawv thov software sib xws.

 

RFID Application System Software

 

 

RFID Application System Softwareyog software tsim rau cov kev xav tau ntawm kev lag luam sib txawv. Nws tuaj yeem tswj hwm tus nyeem ntawv nyeem thiab sau cov ntaub ntawv xov xwm hluav taws xob thiab suav hauv nruab nrab thiab ua cov ntaub ntawv sau tseg.

 

Daim ntawv thov system software tuaj yeem koom ua ke rau hauv e{0}} lag luam thiab e- tsoomfwv platforms, thiab ua ke nrog cov tshuab xws liERP, CRM, thiabWMStxhawm rau txhim kho kev ua haujlwm ntau lawm thoob plaws ntau yam kev lag luam.
