Tus nqi tseem ceeb ntawm PDA handheld scanning terminals yog nyob rau hauv lawv "cov ntaub ntawv tau txais tam sim" muaj peev xwm, uas tso siab rau peb qhov kev siv thev naus laus zis loj: infrared scanning, RFID nyeem ntawv thiab sau ntawv, thiab pom cov duab.
Infrared scanning thev naus laus zis: Los ntawm emitting infrared lub teeb ntawm ib zaus thiab tau txais cov teeb liab sib txawv tshwm sim los ntawm barcodes / QR codes, nws deciphers cov ntaub ntawv encoded. Nyob rau theem kho vajtse, infrared transmitter, receiver, optical system, thiab tswj Circuit Court ua hauj lwm ua ke kom ruaj ntseg nyeem ntawv txawm nyob rau hauv complex teeb pom kev zoo.
RFID nyeem ntawv thiab sau ntawv thev naus laus zis: Tsim nyog rau kev txheeb xyuas cov khoom tsis sib cuag. Thaum lub sijhawm ua haujlwm, lub cuab yeej scanning cheeb tsam yuav tsum tau ua raws li RFID lossis (ntawm qhov deb ntawm ob peb centimeters mus rau kaum centimeters). Thaum ua tiav, nws tuaj yeem nyeem cov ntaub ntawv xws li khoom naj npawb thiab batch tooj. Nws yog feem ntau siv rau cov khoom lag luam warehouse thiab nrhiav cov cuab yeej cuab tam.
Kev paub txog duab thev naus laus zis: tso siab rau siab -pixel koob yees duab thiab AI algorithms, nws txhawb kev kho ntse thiab paub txog QR cov lej thiab cov barcodes puas, txhim kho kev sib raug zoo hauv cov xwm txheej nyuaj.
