ʻO ka mea maʻamau, hiki ke hoʻokaʻawale ʻia ka barcode scanner i ʻelua mau ʻāpana: wired barcode scanner a me wireless barcode scanner e like me ke ʻano o ka lawe ʻana.
Hoʻohana maʻamau ka scanner barcode uea i kahi uea e hoʻohui i kamea heluhelu barcodea me ka lako kamepiula luna no ka launa ʻikepili. Wahi a nā protocols kamaʻilio like ʻole, hiki ke hoʻokaʻawale ʻia lākou i: USB interface, serial interface, keyboard port interface a me nā ʻano mea like ʻole. Hiki ke hoʻokaʻawale ʻia ka hāmeʻa barcode uea i loko o nā ʻāpana e like me ke kaʻina hoʻoili uila: 2.4G uea, Bluetooth,433Hz,zegbee, WiFi.Wired barcode scanner communication interface1. ʻO ke kikowaena USB ʻO ka interface USB ka mea i hoʻohana nui ʻia no nā scanner barcode, a hiki ke hoʻohana pinepine ʻia i nā ʻōnaehana Windows, MAC OS, Linux, Unix, Android a me nā ʻōnaehana ʻē aʻe.
Hiki i ke kelepona USB ke kāko'o i nā ka'ina kama'ilio protocol 'ekolu. , a ʻaʻole kākoʻo i ka mana hoʻomaka kauoha. E hoʻohana maʻamau i ka Notepad, WORD, notepad++ a me nā mea hana kikokikona e hoʻāʻo ai.USB-COM: USB virtual serial port (Virtual Serial Port). Ke hoʻohana nei i kēia pānaʻi kamaʻilio, pono e hoʻokomo i kahi mea hoʻokele awa serial virtual. ʻOiai ua hoʻohana ʻia kahi interface USB kino, he kamaʻilio port serial analog, hiki ke kākoʻo i ka mana hoʻoiho kauoha, a pono e hoʻohana ʻia. ʻO ka hoʻāʻo ʻana i nā hāmeʻa port Serial, e like me ke kōkua debugging port serial etc.USB-HID: ʻIke ʻia hoʻi ʻo HID-POS, he protocol transmission USB kiʻekiʻe. ʻAʻole pono e hoʻokomo i nā mea hoʻokele. Pono ʻo ia e hoʻomohala i ka lako polokalamu loaʻa like no ka launa ʻana i ka ʻikepili a hiki ke kākoʻo i ka mana hoʻoiho kauoha.
2.serial portThe serial port interface ua kapa ʻia hoʻi ka serial communication a i ʻole serial communication interface (i kapa mau ʻia ʻo COM interface). Hoʻohana nui ʻia ia ma ke kahua ʻoihana. Loaʻa iā ia nā hiʻohiʻona o ka mamao hoʻouna lōʻihi, kamaʻilio kūpaʻa a hilinaʻi, ʻaʻole hilinaʻi i nā ʻōnaehana paʻakikī. He ʻano like ʻole kona ʻano hana, e like me DuPont line, 1.25 terminal line, 2.0 terminal line, 2.54 terminal line, a pēlā aku. pin serial port (DB9). Ke hoʻohana nei i ka port serial, pono ʻoe e hoʻolohe i ka protocol kamaʻilio (helu port, parity bit, data bit, stop bit, etc.). Eia kekahi laʻana, ka protocol port serial i hoʻohana pinepine ʻia: 9600, N, 8, 1.TTL interface: ʻO ke kikowaena TTL kahi ʻano o ka port serial, a ʻo ka mea hoʻopuka he hōʻailona pae. Inā pili pono ia i ke kamepiula, ua pōʻino ka puka. Hiki iā TTL ke lilo i kamaʻilio RS232 ma o ka hoʻohui ʻana i kahi chip port serial (e like me SP232, MAX3232). Hoʻohana mau ʻia kēia ʻano o ka interface e hoʻopili i kahi microcomputer chip hoʻokahi. E hoʻohana maʻamau i ka laina DuPont a i ʻole ka laina hope e hoʻopili pololei i nā pine VCC, GND, TX, RX ʻehā e kamaʻilio. Kākoʻo i ke kauoha trigger.RS232 interface: RS232 interface, i ʻike ʻia ʻo COM port, he awa serial maʻamau, hiki ke hoʻopili pololei ʻia i nā lako kamepiula. Ke hoʻohana ʻia, koi ʻia nā mea hana port serial no ka hoʻopuka maʻamau, e like me ke kōkua debugging port serial, hyper terminal a me nā mea hana ʻē aʻe. ʻAʻole pono e hoʻokomo i kahi hoʻokele. Kākoʻo i ka hoʻomaka kauoha.
3.keyboard port interfaceThe keyboard port interface is also called PS/2 interface, KBW (Keyboard Wedge) interface, is a 6-pin circular interface, an interface method used in early keyboards, now used less, the barcode keyboard keyboard port wire is ʻO ka maʻamau ʻekolu ʻElua mau mea hoʻohui, hoʻopili ʻia kekahi i ka hāmeʻa barcode, hoʻopili ʻia kekahi i ka papa keyboard a pili kekahi i ke kamepiula hoʻokipa. Hoʻohana maʻamau i nā huaʻōlelo ma ke kamepiula, hoʻopili a pāʻani.
4. nā ʻano mea ʻē aʻe Ma waho aʻe o nā mea i hoʻopili ʻia ma luna nei, e hoʻohana ka bar coder i kekahi mau ʻano ʻano o ke kamaʻilio ʻana, e like me ke kamaʻilio Wiegand, ke kamaʻilio 485, ke kamaʻilio awa pūnaewele TCP/IP a pēlā aku. ʻAʻole hoʻohana nui ʻia kēia mau ʻano kamaʻilio, ma muli o ke ʻano kamaʻilio TTL me ke ʻano hoʻololi e pili ana i hiki ke hoʻokō ʻia, a ʻaʻole au e hoʻolauna iā lākou i nā kikoʻī ma aneʻi. Wireless Barcode Scanner Communication Interface1.
ʻO 2.4GHz2.4GHz uea ʻole e pili ana i kahi pūʻulu alapine hana.
1.2.4GHzʻO ISM (Industry Science Medicine) kahi kāʻei alapine uila i hoʻohana nui ʻia ma ka honua. Ke hana nei ka ʻenehana Bluetooth i kēia pūʻulu alapine. ʻO ka hana ʻana ma ka band frequency 2.4GHz hiki ke loaʻa i kahi ākea nui o ka hoʻohana. A ʻoi aku ka ikaika anti-interference, i kēia manawa i hoʻohana nui ʻia i ka ʻohana a me nā ʻoihana kalepa. ʻO ka ʻenehana i hoʻohana ʻia no ka hoʻouna ʻana a me ka conduction. kahi mamao hoʻoili waho o 100-200 mika, a ʻo ia hoʻi ka mea hoʻohana maʻamau barcode scanner. He ala kamaʻilio uea ʻole. , Akā, no ka mea he pōkole ka hawewe nalu 2.4G a ua nāwaliwali ka hiki ke komo i ke alapine kiʻekiʻe, hiki i ka mamao o ka hoʻouna ʻana i loko o ka hale ke hiki i 10-30 mika wale nō. Pono ka poʻe heluhelu barcode 2.4G ueʻole e hoʻolako i kahi mea hoʻokipa 2.4G i hoʻopili ʻia i loko o ka mea hoʻokipa no ka lawe ʻana i ka ʻikepili.
2. uʻi Bluetooth Bluetooth ʻO ka pūʻulu o Bluetooth he 2400-2483.5MHz (me ka hui kiaʻi). ʻO kēia ka 2.4 GHz pōkole pōkole lekiō uila no ka hui ʻoihana, ʻepekema, a me ka lāʻau lapaʻau (ISM) ʻaʻole pono i ka laikini (akā ʻaʻole i hoʻoponopono ʻia) ma ka honua holoʻokoʻa. i hoʻouna ʻia ma o 79 mau kaha Bluetooth i koho ʻia. ʻO ka bandwidth o kēlā me kēia kahawai he 1 MHz. Hoʻohana ʻo Bluetooth 4.0 i ka 2 MHz spacing a hiki ke hoʻokomo i nā kaha 40. Hoʻomaka ka kaha mua ma 2402 MHz, hoʻokahi kaha no 1 MHz, a pau i 2480 MHz. Me ka hana Adaptive Frequency-Hopping (AFH), he 1600 mau manawa i kēlā me kēia kekona. Hiki ke hoʻopili ʻia i kahi hāmeʻa me ka hana Bluetooth ma o nā ʻano kamaʻilio like ʻole (e like me HID, SPP, BLE), a hiki ke hoʻopili pū ʻia i kahi kamepiula me ka hana ʻole o ka Bluetooth ma o ka mea hoʻokipa Bluetooth. ʻOi aku ka maʻalahi o ka hoʻohana. Hoʻohana maʻamau ka poʻe heluhelu barcode Bluetooth Wireless Class2 low-power Bluetooth mode, he haʻahaʻa ka hoʻohana ʻana i ka mana, akā pōkole ka mamao o ka hoʻouna ʻana, a ʻo ka mamao hoʻouna maʻamau ma kahi o 10 mika.433MHz, Zeggbe, Wifi a me nā ʻano hana kelepona ʻole. ʻO nā hiʻohiʻona o ka uila 433MHz ka lōʻihi haʻahaʻa haʻahaʻa, ka hiki ke komo ikaika, ka lōʻihi o ke kamaʻilio ʻana, akā nāwaliwali ka mana anti-interference, antenna nui, a me ka mana. Hoʻohana kiʻekiʻe; ʻO nā huahana e hoʻohana ana i ka ʻenehana kamaʻilio Zeggbe kelepona i hiki ke hiki i ka pūnaewele hōkū; ʻAʻole hoʻohana ʻia ʻo Wifi uila ma ke kahua noiʻi pū scanning, a ʻoi aku ka hoʻohana ʻana i ka ʻohi, no laila ʻaʻole wau e hoʻolauna iā ia i nā kikoʻī ma aneʻi.
Ma o ka ʻike ma luna, hiki iā mākou ke hoʻomaopopo maopopo i kekahi mau ala kamaʻilio o ka scanner barcoder maʻamau, a hāʻawi i kahi kuhikuhi no ke koho ʻana i kahi huahana scanner barcode kūpono i ka pae hope. No ka ʻike hou aku e pili ana i ka barcode scanner, aloha maikāhea iā mā˚ou!Email：admin@minj.cn
