Kuphatikiza pa USB, ndi njira zina ziti zoyankhulirana (mitundu yamawonekedwe) zomwe zilipo pa scanner ya barcode?

Nthawi zambiri, scanner ya barcode imatha kugawidwa m'magulu awiri: scanner ya barcode yokhala ndi ma waya ndi barcode scanner yopanda zingwe kutengera mtundu wapatsira.

Wired barcode scanner nthawi zambiri amagwiritsa ntchito waya kulumikizawowerenga barcodendi chipangizo chapamwamba chapakompyuta cholumikizirana ndi data. Malinga ndi njira zosiyanasiyana zoyankhulirana, nthawi zambiri amatha kugawidwa kukhala: mawonekedwe a USB, mawonekedwe a serial, mawonekedwe a doko la kiyibodi ndi mitundu ina yolumikizirana. Chipangizo cha barcode opanda zingwe chingathenso kugawidwa m'magulu otsatirawa malinga ndi ndondomeko yotumizira opanda zingwe: opanda zingwe 2.4G, Bluetooth,433Hz,zegbee, WiFi.Wired barcode scanner interface1. Mawonekedwe a USBMawonekedwe a USB ndi mawonekedwe omwe amagwiritsidwa ntchito kwambiri pamasina a barcode, ndipo amatha kugwiritsidwa ntchito pamakina a Windows, MAC OS, Linux, Unix, Android ndi machitidwe ena.

Mawonekedwe a USB nthawi zambiri amatha kuthandizira njira zitatu zotsatirazi zoyankhulirana zama protocol.USB-KBW: USB kiyibodi doko, ofanana ndi njira yogwiritsira ntchito USB kiyibodi, ndi ambiri ntchito njira kulankhulana, pulagi ndi kusewera, safuna kukhazikitsa madalaivala. , ndipo sichigwirizana ndi kuwongolera koyambitsa. Nthawi zambiri gwiritsani ntchito Notepad, WORD, notepad ++ ndi zida zina zotulutsa mawu kuti muyese.USB-COM: USB virtual serial port (Virtual Serial Port). Mukamagwiritsa ntchito njira yolumikiziranayi, nthawi zambiri pamafunika kukhazikitsa dalaivala wa serial port. Ngakhale mawonekedwe amtundu wa USB amagwiritsidwa ntchito, ndi kulumikizana kwa doko la analogi, komwe kumatha kuthandizira kuwongolera koyambitsa, ndipo nthawi zambiri kumafunika kugwiritsidwa ntchito. Kuyesa kwa zida za doko, monga serial port debugging assistant etc.USB-HID: Imadziwikanso kuti HID-POS, ndi protocol yothamanga kwambiri ya USB. Siziyenera kukhazikitsa madalaivala. Nthawi zambiri imayenera kupanga pulogalamu yofananira yolandila kuti igwirizane ndi data ndipo imatha kuthandizira kuwongolera zoyambitsa.

2.serial portThe serial port interface imatchedwanso serial communication kapena serial communication interface (yomwe nthawi zambiri imatchedwa mawonekedwe a COM). Nthawi zambiri amagwiritsidwa ntchito m'mafakitale. Zili ndi makhalidwe a mtunda wautali wotumizira, kulankhulana kokhazikika komanso kodalirika, ndipo sikudalira machitidwe ovuta. Mawonekedwe ake ndi Njira Zosiyanasiyana, monga DuPont line, 1.25 terminal line, 2.0 terminal line, 2.54 terminal line, etc. pini siriyo doko (DB9). Mukamagwiritsa ntchito doko la serial, muyenera kulabadira njira yolumikizirana (chiwerengero cha doko, parity bit, data bit, stop bit, etc.). Mwachitsanzo, ma protocol omwe amagwiritsidwa ntchito nthawi zambiri: 9600, N, 8, 1.TTL mawonekedwe: mawonekedwe a TTL ndi mtundu wa doko losalekeza, ndipo zotulukapo ndi chizindikiro. Ngati chikugwirizana mwachindunji ndi kompyuta, linanena bungwe ndi garbled. TTL ikhoza kukhala kulumikizana kwa RS232 powonjezera chip serial port (monga SP232, MAX3232). Mawonekedwe amtunduwu nthawi zambiri amagwiritsidwa ntchito kulumikiza kachipangizo kakang'ono kachipangizo kakang'ono. Nthawi zambiri gwiritsani ntchito mzere wa DuPont kapena mzere wotsiriza kuti mulumikizane ndi VCC, GND, TX, RX mapini anayi kuti mulumikizane. Support command trigger.RS232 interface: RS232 interface, yomwe imadziwikanso kuti COM port, ndi doko lokhazikika, lomwe nthawi zambiri limatha kulumikizidwa mwachindunji ndi zida zamakompyuta. Zikagwiritsidwa ntchito, zida za serial port zimafunikira kuti zitheke bwino, monga serial port debugging assistant, hyper terminal ndi zida zina. Palibe chifukwa choyika dalaivala. Thandizo la lamulo loyambitsa.

3.keyboard port interfaceMawonekedwe a doko la kiyibodi amatchedwanso mawonekedwe a PS/2, mawonekedwe a KBW (Keyboard Wedge), ndi mawonekedwe ozungulira a 6-pin, njira yolumikizira yomwe imagwiritsidwa ntchito pamakiyibodi oyambirira, omwe amagwiritsidwa ntchito pang'ono, waya wa barcode kiyibodi nthawi zambiri atatu Pali zolumikizira ziwiri, chimodzi chimalumikizidwa ndi chipangizo cha barcode, chimodzi chimalumikizidwa ndi kiyibodi ya kompyuta ndipo chimzake chimalumikizidwa ndi kompyuta yolandila. Nthawi zambiri gwiritsani ntchito mawu otuluka pakompyuta, pulagi ndi kusewera.

4. mitundu ina ya ma interfacesKuwonjezera pa mawaya angapo omwe ali pamwambawa, bar coder idzagwiritsanso ntchito njira zina zoyankhulirana, monga Wiegand communication, 485 communication, TCP/IP network port communication ndi zina zotero. Njira zoyankhuliranazi nthawi zambiri sizimagwiritsidwa ntchito kwambiri, nthawi zambiri zimatengera njira yolankhulirana ya TTL kuphatikiza gawo losinthika lofananira limatha kukwaniritsidwa, ndipo sindidzawafotokozera mwatsatanetsatane apa.Wireless Barcode Scanner Communication Interface1.

 

Wopanda zingwe 2.4GHz2.4GHz amatanthauza gulu la ma frequency ogwirira ntchito.

1.2.4 GHzISM (Industry Science Medicine) ndi gulu la ma frequency opanda zingwe lomwe limagwiritsidwa ntchito poyera padziko lonse lapansi. Tekinoloje ya Bluetooth imagwira ntchito mu band ya frequency iyi. Kugwira ntchito mu 2.4GHz frequency band kumatha kugwiritsa ntchito mokulirapo. Ndipo mphamvu zotsutsana ndi kusokoneza, zomwe zimagwiritsidwa ntchito kwambiri m'nyumba ndi malonda. Tekinoloje yomwe imagwiritsidwa ntchito potumiza maulendo ang'onoang'ono opanda zingwe ndi ma conduction.Protocol yolumikizirana yopanda zingwe ya 2.4G ili ndi ntchito zambiri, ndipo ili ndi maubwino othamanga mwachangu, kugwiritsa ntchito mphamvu pang'ono, kuphatikizika kosavuta, ndi zina. The wireless 2.4G barcode scanner nthawi zambiri imakhala mtunda wotumizira panja wa 100-200 metres, komanso ndi scanner yomwe imagwiritsidwa ntchito kwambiri. Njira yolumikizirana opanda zingwe. , Koma chifukwa 2.4G wavelength ndi lalifupi ndi mkulu pafupipafupi malowedwe mphamvu ndi ofooka, ambiri m'nyumba kufala mtunda akhoza kufika mamita 10-30. Owerenga barcode opanda zingwe a 2.4G nthawi zambiri amafunika kukhala ndi cholandila cha 2.4G cholumikizidwa ndi chipangizocho kuti atumize deta.

2. Bluetooth opanda zingwe Bluetooth Gulu la Bluetooth ndi 2400-2483.5MHz (kuphatikiza gulu la alonda). Iyi ndi 2.4 GHz short-range radio frequency band ya mafakitale, sayansi, ndi zamankhwala (ISM) bandi yomwe simafuna laisensi (koma osati yosaloledwa) padziko lonse lapansi.Bluetooth imagwiritsa ntchito ukadaulo wa frequency hopping kugawa zomwe zimatumizidwa mu mapaketi a data, zomwe zimafalitsidwa kudzera mumayendedwe 79 osankhidwa a Bluetooth. Bandwidth ya njira iliyonse ndi 1 MHz. Bluetooth 4.0 imagwiritsa ntchito malo a 2 MHz ndipo imatha kukhala ndi mayendedwe 40. Njira yoyamba imayambira pa 2402 MHz, njira imodzi pa 1 MHz, ndipo imatha pa 2480 MHz. Ndi ntchito ya Adaptive Frequency-Hopping (AFH), nthawi zambiri imadumphira maulendo 1600 pa sekondi. Itha kulumikizidwa ku chipangizo chokhala ndi ntchito ya Bluetooth kudzera munjira zosiyanasiyana zolankhulirana (monga HID, SPP, BLE), komanso imatha kulumikizidwa ndi kompyuta popanda ntchito ya Bluetooth kudzera pa cholandila cha Bluetooth. Ndizosavuta kugwiritsa ntchito. Owerenga barcode opanda zingwe a Bluetooth nthawi zambiri amagwiritsa ntchito Class2 low-power Bluetooth mode, yomwe imakhala ndi mphamvu zochepa, koma mtunda wotumizira ndi waufupi, ndipo mtunda wapadziko lonse ndi pafupifupi mita 10. Pali njira zina zolumikizirana opanda zingwe monga433MHz, Zeggbe, Wifi ndi njira zina zoyankhulirana zopanda zingwe. Makhalidwe a 433MHz opanda zingwe ndi kutalika kwa mafunde, mafupipafupi otsika, kuthekera kolowera mwamphamvu, mtunda wautali wolankhulana, koma kufooka koletsa kusokoneza, mlongoti waukulu, ndi mphamvu. Kudya kwambiri; mankhwala ntchito opanda zingwe Zeggbe kulankhulana luso ndi luso nyenyezi Intaneti; Wifi opanda zingwe sagwiritsidwa ntchito pang'onopang'ono m'malo ogwiritsira ntchito mfuti, komanso amagwiritsidwa ntchito kwambiri posonkhanitsa, kotero sindifotokoza mwatsatanetsatane apa.

Kupyolera muzomwe zili pamwambazi, titha kumvetsetsa bwino njira zina zoyankhulirana za barcode scanner wamba, ndikupereka maumboni osankha chinthu choyenera cha barcode scanner mtsogolo. Kuti mudziwe zambiri za barcode scanner, landirani kuLumikizanani nafe!Email:admin@minj.cn
