RFID yog dab tsi?

RFID (Radio Frequency Identification) yog ib hom kev sib txuas lus wireless uas sib txuas nrog kev siv hluav taws xob los yog electrostatic coupling nyob rau hauv xov tooj cua zaus ntawm cov electromagnetic spectrum kom cim tus yam khoom, tsiaj, los yog neeg.RFID yog siv nyob rau hauv ntau yam kev siv. , nrog rau cov ntawv thov xws li tsiaj microchips, automotive microchip anti-tub sab tub nyiag khoom, kev nkag mus, tswj chaw nres tsheb, cov kab ntau lawm automation, thiab kev tswj cov khoom siv.

Nws ua haujlwm li cas?

RFID system yog tsim los ntawm peb lub hauv paus tseem ceeb: cov cim npe hluav taws xob, kav hlau txais xov thiab nyeem ntawv.

Electronic tags: tseem hu ua transponders, nyob rau hauv cov khoom uas tau txheeb xyuas, yog cov ntaub ntawv nqa khoom nyob rau hauv RFID system, khaws cia cov khoom cov ntaub ntawv tshwj xeeb.

Kav hlau txais xov: Siv rau kev xa xov tooj cua xa xov tooj cua, txuas tus nyeem ntawv thiab cov cim npe, paub txog kev xa cov ntaub ntawv wireless.

Nyeem ntawv: Siv los nyeem cov ntaub ntawv hauv daim ntawv lo thiab xa mus rau cov ntaub ntawv ua haujlwm rau kev ua haujlwm ntxiv.

 

Cov txheej txheem ua haujlwm ntawm RFID thev naus laus zis yog kwv yees li hauv qab no:

Cov txheej txheem txheeb xyuas: Thaum ib yam khoom uas muaj lub cim hluav taws xob nkag mus rau qhov kev txheeb xyuas ntawm tus nyeem ntawv, tus nyeem ntawv xa xov tooj cua los qhib lub cim hluav taws xob.

Cov ntaub ntawv xa mus: Tom qab lub cim hluav taws xob tau txais lub teeb liab, nws xa cov ntaub ntawv khaws cia rov qab rau tus nyeem ntawv los ntawm tus kav hlau txais xov.

Kev ua cov ntaub ntawv: Tom qab tus nyeem tau txais cov ntaub ntawv, nws ua tiav los ntawm cov khoom nruab nrab, thiab thaum kawg xa cov ntaub ntawv ua tiav rau lub khoos phis tawj lossis lwm cov ntaub ntawv ua haujlwm.
