Feem ntau, barcode scanner tuaj yeem muab faib ua ob pawg: wired barcode scanner thiab wireless barcode scanner raws li hom kev sib kis.
Wired barcode scanner feem ntau siv cov xaim los txuas raubarcode nyeem ntawvthiab lub khoos phis tawj sab saud rau kev sib txuas lus cov ntaub ntawv. Raws li cov kev sib txuas lus sib txawv, feem ntau lawv tuaj yeem muab faib ua: USB interface, serial interface, keyboard port interface thiab lwm yam interfaces. Lub wireless barcode ntaus ntawv tseem tuaj yeem muab faib ua pawg hauv qab no raws li kev sib txuas lus wireless: wireless 2.4G, Bluetooth, 433Hz, zegbee, WiFi.Wired barcode scanner kev sib txuas lus interface1. USB interface Lub USB interface yog qhov feem ntau siv interface rau barcode scanners, thiab feem ntau tuaj yeem siv rau Windows systems, MAC OS, Linux, Unix, Android thiab lwm lub tshuab.
USB interface feem ntau tuaj yeem txhawb nqa peb txoj kev sib txuas lus sib txawv hauv qab no.USB-KBW: USB keyboard chaw nres nkoj, zoo ib yam li txoj kev siv USB keyboard, yog txoj kev sib txuas lus ntau tshaj plaws, ntsaws thiab ua si, tsis tas yuav nruab cov tsav tsheb. , thiab tsis txhawb kev hais kom ua kev tswj hwm. Feem ntau siv Notepad, WORD, notepad ++ thiab lwm cov ntawv tso tawm cov cuab yeej los sim.USB-COM: USB virtual serial chaw nres nkoj (Virtual Serial Port). Thaum siv qhov kev sib txuas lus no, feem ntau nws yog qhov tsim nyog rau nruab ib lub chaw nres nkoj virtual tsav. Txawm hais tias siv lub cev USB interface, nws yog ib qho analog serial chaw nres nkoj kev sib txuas lus, uas tuaj yeem txhawb nqa kev tswj hwm kev tswj hwm, thiab feem ntau yuav tsum tau siv. Serial chaw nres nkoj cov cuab yeej kuaj, xws li serial chaw nres nkoj debugging assistant etc.USB-HID: Kuj hu ua HID-POS, nws yog ib tug high-ceev USB kis raws tu qauv. Nws tsis tas yuav nruab cov tsav tsheb. Nws feem ntau yuav tsum tsim kom muaj qhov sib txuam tau txais software rau cov ntaub ntawv sib cuam tshuam thiab tuaj yeem txhawb nqa kev tswj hwm kev tswj hwm.
2.serial portThe serial port interface tseem hu ua serial kev sib txuas lus lossis serial kev sib txuas lus interface (feem ntau hu ua COM interface). Nws feem ntau yog siv dav hauv kev lag luam. Nws muaj cov yam ntxwv ntawm kev sib kis ntev, kev sib txuas lus ruaj khov thiab txhim khu kev qha, thiab tsis nyob ntawm cov txheej txheem nyuaj. Nws txoj kev sib txuas yog ntau yam ntau yam, xws li DuPont kab, 1.25 davhlau ya nyob twg kab, 2.0 davhlau ya nyob twg kab, 2.54 davhlau ya nyob twg kab, thiab lwm yam. Tam sim no, lub scanner feem ntau siv TTL theem teeb liab thiab RS232 teeb liab tso zis, thiab lub cev interface feem ntau yog 9- tus pin serial chaw nres nkoj (DB9). Thaum siv qhov chaw nres nkoj serial, koj yuav tsum tau them sai sai rau kev sib txuas lus raws tu qauv (chaw nres nkoj naj npawb, parity me ntsis, cov ntaub ntawv me, nres me ntsis, thiab lwm yam). Piv txwv li, feem ntau siv serial chaw nres nkoj raws tu qauv: 9600, N, 8, 1.TTL interface: TTL interface yog ib hom serial chaw nres nkoj, thiab cov zis yog ib theem teeb liab. Yog hais tias nws yog ncaj qha mus rau lub computer, cov zis yog garbled. TTL tuaj yeem dhau los ua RS232 kev sib txuas lus los ntawm kev ntxiv ib qho chaw nres nkoj nti (xws li SP232, MAX3232). Hom kev sib txuas no feem ntau yog siv los txuas ib leeg-chip microcomputer. Feem ntau siv DuPont kab lossis kab davhlau ya nyob twg los txuas ncaj qha rau VCC, GND, TX, RX plaub tus pins sib txuas lus. Txhawb kev hais kom ua trigger.RS232 interface: RS232 interface, tseem hu ua COM chaw nres nkoj, yog qhov chaw nres nkoj txheem, uas feem ntau tuaj yeem txuas ncaj qha rau cov khoom siv hauv computer. Thaum siv, serial chaw nres nkoj cov cuab yeej yuav tsum tau rau ib txwm tso zis, xws li serial chaw nres nkoj debugging pab, hyper terminal thiab lwm yam cuab yeej. Tsis tas yuav nruab tus tsav tsheb. Txhawb kev hais kom ua.
3.keyboard chaw nres nkoj interfaceCov keyboard chaw nres nkoj interface kuj hu ua PS/2 interface, KBW (Keyboard Wedge) interface, yog 6-pin ncig interface, ib qho kev sib txuas siv hauv cov keyboards thaum ntxov, tam sim no siv tsawg dua, barcode keyboard keyboard chaw nres nkoj hlau yog feem ntau peb muaj ob lub connectors, ib tug yog txuas nrog lub barcode ntaus ntawv, ib tug yog txuas nrog lub computer keyboard thiab lwm yam yog txuas nrog lub party computer. Feem ntau siv cov ntawv sau tawm ntawm lub computer, ntsaws thiab ua si.
4. Lwm hom kev sib txuas Ntxiv rau saum toj no ob peb wired interfaces, bar coder kuj tseem yuav siv lwm hom kev sib txuas lus, xws li Wiegand kev sib txuas lus, 485 kev sib txuas lus, TCP / IP network chaw nres nkoj kev sib txuas lus thiab lwm yam. Cov kev sib txuas lus no feem ntau tsis siv ntau, feem ntau yog raws li TTL txoj kev sib txuas lus ntxiv rau cov kev hloov pauv hloov tau zoo tuaj yeem paub, thiab kuv yuav tsis qhia lawv kom meej ntawm no.Wireless Barcode Scanner Kev Sib Txuas Lus Interface1.
Wireless 2.4GHz 2.4GHz yog hais txog kev ua haujlwm zaus.
1.2.4GHz ceevISM (Industry Science Medicine) yog lub wireless zaus band uas tau siv rau pej xeem hauv ntiaj teb. Bluetooth technology ua haujlwm nyob rau hauv no zaus band. Ua haujlwm hauv 2.4GHz zaus band tuaj yeem tau txais ntau yam kev siv. Thiab muaj zog tiv thaiv kev cuam tshuam muaj peev xwm, tam sim no dav siv hauv tsev thiab kev lag luam. Technology siv rau kev sib txuas lus luv luv wireless thiab conduction.The wireless 2.4G kev sib txuas lus raws tu qauv muaj ntau yam kev siv, thiab muaj qhov zoo ntawm kev sib kis ceev ceev, tsis tshua muaj zog noj, yooj yim khub, thiab lwm yam. Lub wireless 2.4G barcode scanner feem ntau muaj. ib qho kev sib kis sab nraum zoov ntawm 100-200 meters, thiab nws kuj yog qhov feem ntau siv barcode scanner. Ib txoj kev sib txuas lus wireless. , Tab sis vim hais tias 2.4G wavelength yog luv luv thiab qhov muaj peev xwm nkag mus rau qhov muaj peev xwm tsis muaj zog, qhov kev sib kis sab hauv tsev tsuas yog ncav cuag 10-30 meters. Wireless 2.4G barcode nyeem ntawv feem ntau yuav tsum tau nruab nrog 2.4G receiver ntsaws rau hauv lub cuab yeej cuab tam rau kev xa cov ntaub ntawv.
2. wireless Bluetooth BluetoothCov band ntawm Bluetooth yog 2400-2483.5MHz (xws li tus neeg zov band). Qhov no yog 2.4 GHz luv-ntau lub xov tooj cua zaus band rau kev lag luam, kev tshawb fawb, thiab kev kho mob (ISM) band uas tsis xav tau daim ntawv tso cai (tab sis tsis muaj kev tswj hwm) thoob ntiaj teb.Bluetooth siv zaus hopping thev naus laus zis los faib cov ntaub ntawv xa mus rau hauv cov ntaub ntawv pob, uas tau sib kis los ntawm 79 txoj kev xaiv Bluetooth. Bandwidth ntawm txhua channel yog 1 MHz. Bluetooth 4.0 siv 2 MHz sib nrug thiab tuaj yeem ua tau 40 raws. Thawj channel pib ntawm 2402 MHz, ib channel ib 1 MHz, thiab xaus ntawm 2480 MHz. Nrog Adaptive Frequency-Hopping (AFH) muaj nuj nqi, nws feem ntau hops 1600 zaug ib ob.Lub wireless Bluetooth barcode nyeem ntawv muaj qhov tseem ceeb heev. Nws tuaj yeem txuas nrog lub cuab yeej nrog Bluetooth ua haujlwm los ntawm ntau txoj kev sib txuas lus (xws li HID, SPP, BLE), thiab nws tseem tuaj yeem txuas nrog lub khoos phis tawj yam tsis muaj Bluetooth ua haujlwm los ntawm Bluetooth txais. Nws yog siv tau yooj yim dua. Wireless Bluetooth barcode nyeem ntawv feem ntau siv Class2 low-power Bluetooth hom, uas muaj kev siv hluav taws xob tsawg, tab sis qhov kev sib kis tau luv luv, thiab kev sib kis dav dav yog li 10 meters.Muaj lwm txoj kev sib txuas lus wireless xws li433 MHz, Zeggbe, Wifi thiab lwm txoj kev sib txuas lus wireless. Cov yam ntxwv ntawm wireless 433MHz yog qhov ntev wavelength, tsawg zaus, muaj peev xwm nkag mus tau zoo, kev sib txuas lus ntev, tab sis tsis muaj peev xwm tiv thaiv kev cuam tshuam, kav hlau txais xov loj, thiab lub zog. Kev siv siab; cov khoom siv wireless Zeggbe kev sib txuas lus thev naus laus zis muaj peev xwm ntawm kev sib txuas hnub qub; wireless Wifi tsis tshua siv nyob rau hauv daim ntawv thov phom scanning, thiab siv ntau dua nyob rau hauv lub collector, yog li kuv yuav tsis qhia nws kom meej ntawm no.
Los ntawm cov ntaub ntawv saum toj no, peb tuaj yeem nkag siab meej txog qee txoj kev sib txuas lus ntawm cov khoom siv barcode scanner, thiab muab cov ntaub ntawv siv rau kev xaiv cov khoom siv barcode scanner tsim nyog nyob rau theem tom ntej.
