Nyeem tau Writable RFID Barcode Scanner

HW-1870C Readable Writable RFID Barcode Scanner yog ib qho kev ua haujlwm siab embedded module, ntxiv rau kev nyeem 1D 2D barcode QR code, nws tseem tuaj yeem nyeem RFID mifare card, lub kauj yog tag nrho ua ke hauv module (tsis muaj tus kav hlau txais xov sab nraud) , cov barcode thiab daim npav tswj hwm tau koom ua ke hauv PCB. Cov khoom no tsuas yog siv los ua ke rau hauv cov khoom siv rau kev pabcuam tus kheej, uas tuaj yeem siv rau kev ua tswvcuab daim npav rau tus kheej nug, rov them dua, noj, thiab lwm yam.; Nws tseem tuaj yeem siv rau hauv kev tswj hwm kev nkag mus, nyeem ntawv thiab sau ntawv tswj kev nkag mus, thiab qhib qhov rooj nrog QR cov lej rau cov qhua ib ntus.

HW-1870C barcode nyeem ntawv kev ua tau zoo yog qhov muaj zog, siv lub koob yees duab kis thoob ntiaj teb, 1GHz MCU cov ntaub ntawv muaj peev xwm ua tau zoo heev, tus nqi refresh tuaj yeem ncav cuag 60fps, cov neeg siv kev paub zoo heev; nyob rau hauv IC daim npav cov ntaub ntawv ua, nws tuaj yeem nyeem tau ceev daim npav thiab cov ntaub ntawv tawm mus rau lub cev, thiab nws kuj tseem siv tau los ua cov khoom siv sau ntawv. Nws yog ib qho tsim nyog los teeb tsa lub module kom nkag mus rau hom kev hais kom ua, thiab tom qab xa cov lus txib los ntawm qhov chaw nres nkoj serial, nws tuaj yeem ua haujlwm ntawm daim npav sau ntawv.

A: Qauv hauv 3 hnub ua haujlwm. thiab yog tias muaj Tshuag tuaj yeem xa tawm tam sim, yog OEM lossis ODM tsim. hnub xa khoom yog li 2 lub lis piam.

5. Kuv puas tuaj yeem tau txais qee cov qauv ntawm cov ntawv nyeem tau RFID barcode scanner? Lawv puas yog dawb?

A: Peb txhawb 1pc qauv txiav txim. Cov qauv yuav tsum tau them.Yog tias koj yuav ntau 200pcs, peb yuav rov qab cov nqi coj mus kuaj (suav nrog tus nqi thauj khoom.

Kev paub txog kev lag luam: Lub hauv paus ntsiab lus ntawm IC daim npav nyeem thiab sau ntawv

Lub Readable Writable RFID Barcode Scanner xa ib txheej ntawm electromagnetic nthwv dej nrog lub sijhawm ruaj khov rau daim npav IC. Muaj LC series resonant Circuit Court nyob rau hauv daim npav, thiab nws zaus yog tib yam li cov zaus tawm los ntawm tus nyeem ntawv. Nyob rau hauv txoj kev no, nyob rau hauv lub excitation ntawm electromagnetic tsis, LC resonant Circuit Court resonates, kom lub capacitance muaj ib tug nqi nyob rau hauv.

Ntawm qhov kawg ntawm lub capacitor no, lub twj tso kua mis unidirectional txuas nrog xa cov nqi hauv lub capacitor mus rau lwm lub capacitor cia. Thaum cov nqi them nce mus txog 2V, lub capacitor no tuaj yeem siv los ua cov khoom siv hluav taws xob los muab kev ua haujlwm voltage rau lwm cov circuits. Xa cov ntaub ntawv hauv daim npav lossis txais cov ntaub ntawv ntawm RFID Barcode Scanner.
