Ngokubanzi, iskena sebhakhowudi sinokwahlulwa zibe ngamacandelo amabini: iskena sebhakhowudi eneentambo kunye neskena sebhakhowudi engenazingcingo ngokohlobo losasazo.
Wired barcode scanner ngokuqhelekileyo usebenzisa ucingo ukuqhagamshelaumfundi webhakhowudikunye nesixhobo sekhompyutha esiphezulu sonxibelelwano lwedatha. Ngokweeprothokholi zonxibelelwano ezahlukeneyo, zinokwahlulwa zibe: ujongano lwe-USB, ujongano lweserial, ujongano lwezibuko lebhodi yezitshixo kunye nezinye iintlobo zojongano. Isixhobo sebhakhowudi engenazingcingo sinokwahlulwa ngokwezi ndidi zilandelayo ngokwemigaqo yothumelo engenazingcingo: wireless 2.4G, Bluetooth,433Hz,zegbee, WiFi.Wired barcode scanner ujongano lonxibelelwano1. I-interface ye-USBUjongano lwe-USB lolona jongano lusetyenziswa kakhulu kwiskena sebhakhowudi, kwaye luqhele ukusetyenziswa kwiinkqubo zeWindows, iMAC OS, Linux, Unix, Android kunye nezinye iinkqubo.
Ujongano lwe-USB ludla ngokuxhasa ezi ndlela zintathu zilandelayo zonxibelelwano lweprotocol.USB-KBW: USB keyboard port, efana nendlela yokusebenzisa i-USB keyboard, yeyona ndlela ixhaphakileyo yonxibelelwano, iplagi kunye nokudlala, akuyomfuneko ukufaka abaqhubi. , kwaye ayixhasi ulawulo lokuqalisa. Ngokuqhelekileyo sebenzisa i-Notepad, i-WORD, i-notepad ++ kunye nezinye izixhobo zemveliso yombhalo ukuvavanya.USB-COM: i-USB virtual serial port (Virtual Serial Port). Xa usebenzisa olujongano lonxibelelwano, kudla ngokuba yimfuneko ukuhlohla umqhubi we-serial port. Nangona i-interface ye-USB yomzimba isetyenzisiwe, lunxibelelwano lwe-analog serial port, enokuxhasa ulawulo lwe-trigger yomyalelo, kwaye idla ngokufuneka isetyenziswe. Uvavanyo lwesixhobo se-serial port, njenge-serial port debugging assistant etc.USB-HID: Ikwaziwa ngokuba yi-HID-POS, yi-high-speed USB transmission protocol. Akuyomfuneko ukufaka abaqhubi. Ngokuqhelekileyo kufuna ukuphuhlisa isoftware ehambelanayo yokufumana intsebenziswano yedatha kwaye inokuxhasa ulawulo lwetrigger yomyalelo.
2.I-serial portI-serial port interface ikwabizwa ngokuba yi-serial communication okanye i-serial communication interface (edla ngokubizwa ngokuba yi-COM interface). Ngokuqhelekileyo isetyenziswa ngokubanzi kwintsimi yezoshishino. Ineempawu zokuhanjiswa komgama omde, unxibelelwano oluzinzileyo noluthembekileyo, kwaye aluxhomekanga kwiinkqubo ezinzima. iindlela zayo ujongano ezahlukeneyo ezahlukeneyo, ezifana umgca DuPont, 1.25 umgca terminal, 2.0 umgca terminal, 2.54 umgca terminal, njalo njalo. Okwangoku, iskena ngokuqhelekileyo sisebenzisa TTL isiginali kunye RS232 uphawu output, kwaye ujongano ngokomzimba idla ngokuba 9- i-pin ye-serial port (DB9). Xa usebenzisa i-port ye-serial, kufuneka ubeke ingqalelo kwiprotocol yonxibelelwano (inombolo ye-port, i-parity bit, i-data bit, i-stop bit, njl.). Umzekelo, i-serial port protocol esetyenziswa ngokuqhelekileyo: 9600, N, 8, 1.TTL ujongano: Ujongano lweTTL luhlobo lwezibuko lothotho, kwaye imveliso yinqanaba lophawu. Ukuba iqhagamshelwe ngokuthe ngqo kwikhompyuter, imveliso idityanisiwe. I-TTL ingaba yi-RS232 yonxibelelwano ngokongeza i-chip ye-serial port (efana ne-SP232, MAX3232). Olu hlobo lojongano ludla ngokusetyenziswa ukudibanisa i-microcomputer ye-single-chip. Ngesiqhelo sebenzisa umgca weDuPont okanye umgca wetheminali ukuqhagamshela ngqo iVCC ehambelanayo, GND, TX, RX izikhonkwane ezine zokunxibelelana. Inkxaso yomyalelo we-trigger.RS232 interface: I-interface ye-RS232, eyaziwa ngokuba yi-COM port, i-port ye-serial ye-serial, edla ngokudityaniswa ngokuthe ngqo kwizixhobo zekhompyutha. Xa zisetyenziswa, izixhobo ze-port yesiriyali ziyafuneka kwimveliso eqhelekileyo, njenge-serial port debugging assistant, hyper terminal kunye nezinye izixhobo. Akukho mfuneko yokufaka umqhubi. Inkxaso yomyalelo wokuqalisa.
3.ujongano lwezibuko lebhodi yebhodiUjongano lwezibuko lebhodi ikwabizwa ngokuba yi-PS/2 ujongano, KBW (Keyboard Wedge) ujongano, lujongano olusetyhula olu-6-pin, indlela yojongano olusetyenziswa kwiibhodi zakuqala, ezisetyenziswa ngoku ngaphantsi, ibarcode keyboard port wire is ngokuqhelekileyo ezintathu Kukho iziqhagamshelo ezimbini, enye iqhagamshelwe kwisixhobo sebhakhowudi, enye iqhagamshelwe kwikhibhodi yekhompyuter kwaye enye iqhagamshelwe kwikhompyuter yenginginya. Ngokuqhelekileyo sebenzisa imveliso yombhalo kwikhompyuter, iplagi kunye nokudlala.
4. ezinye iintlobo ze-interfacesUkongezelela kule miba ingentla apha ngentla, ibar coder iya kusebenzisa ezinye iindlela zonxibelelwano, ezifana nonxibelelwano lwe-Wiegand, unxibelelwano lwe-485, i-TCP/IP network port communication njalo njalo. Ezi ndlela zonxibelelwano zihlala zingasetyenziswa kakhulu, ngokuqhelekileyo zisekelwe kwindlela yonxibelelwano ye-TTL kunye nemodyuli yokuguqulwa ehambelanayo inokuphunyezwa, kwaye andiyi kubazisa ngokubanzi apha.I-Wireless Barcode Scanner UNxibelelwano lwe-Interface1.
Wireless 2.4GHz2.4GHz ibhekisa kwibhendi yamaza okusebenza.
1.2.4GHzI-ISM (i-Industry Science Medicine) yibhendi yefrikhwensi engenazingcingo esetyenziswa esidlangalaleni kwihlabathi. Itekhnoloji yeBluetooth isebenza kule bhendi yamaza. Ukusebenza kwi-2.4GHz frequency band unokufumana uluhlu olukhulu losetyenziso. Kunye nesakhono esinamandla sokuchasa ukungenelela, ngoku sisetyenziswa ngokubanzi kumasimi asekhaya kunye nezorhwebo. Itekhnoloji esetyenziselwa ukuhanjiswa kwe-wireless kunye nokuqhuba.I-protocol ye-wireless ye-2.4G yonxibelelwano inoluhlu olubanzi lwezicelo, kwaye ineenzuzo zesantya sokuhambisa ngokukhawuleza, ukusetyenziswa kwamandla aphantsi, ukudibanisa okulula, njl njl. umgama wothumelo lwangaphandle we-100-200 yeemitha, kwaye ikwasesona siskena sebhakhowudi sisetyenziswa kakhulu. Indlela yonxibelelwano engenazingcingo. , Kodwa ngenxa yokuba ubude be-2.4G bufutshane kwaye amandla okungena aphezulu anamandla, umgama oqhelekileyo wokuhanjiswa kwangaphakathi ungafikelela kuphela kwi-10-30 yeemitha. Abafundi bebhakhowudi be-2.4G abangenazingcingo badla ngokufuna ukuxhotyiswa ngesamkeli se-2.4G esiplagwe kwisixhobo sokuhambisa idatha.
2. IBluetooth engenazingcingo iBluetoothIbhendi yeBluetooth yi2400-2483.5MHz (kubandakanywa nebhendi yonogada). Le yi-2.4 GHz ibhendi yefrikhwensi yerediyo yoluhlu olufutshane yoshishino, inzululwazi, kunye nezonyango (ISM) ibhendi engafuni layisensi (kodwa ingalawulwayo) kwihlabathi jikelele.IBluetooth isebenzisa ubuchwepheshe be-frequency hopping ukwahlula idatha egqithisiweyo kwiipakethi zedatha, ezisasazwa ngokulandelelana kwiitshaneli ezichongiweyo zeBluetooth ezingama-79. I-bandwidth yetshaneli nganye yi-1 MHz. IBluetooth 4.0 isebenzisa isithuba se-2 MHz kwaye inokwamkela amajelo angama-40. Itshaneli yokuqala iqala kwi-2402 MHz, itshaneli enye nge-1 MHz, kwaye iphele kwi-2480 MHz. Ngomsebenzi we-Adaptive Frequency-Hopping (AFH), idla ngokuxhuma amaxesha angama-1600 ngesekhondi.Umfundi webhakhowudi yeBluetooth engenazingcingo unento ebaluleke kakhulu. Inokuqhagamshelwa kwisixhobo esinomsebenzi weBluetooth ngeendlela ezahlukeneyo zonxibelelwano (ezifana ne-HID, SPP, BLE), kwaye inokudityaniswa nekhompyuter ngaphandle komsebenzi weBluetooth nge-Bluetooth receiver. Iguquguquka ngakumbi ukuyisebenzisa. Abafundi bebhakhowudi yeBluetooth engenazingcingo ngokuqhelekileyo basebenzisa iClass2 yamandla aphantsi imowudi yeBluetooth, esebenzisa amandla aphantsi, kodwa umgama wothumelo umfutshane, kwaye umgama wothumelo jikelele umalunga neemitha ezili-10. Kukho ezinye iindlela zonxibelelwano ezingenazingcingo ezifana433MHz, Zeggbe, Wifi kunye nezinye iindlela zonxibelelwano wireless. Iimpawu ze-433MHz ezingenazingcingo zide ubude, i-frequency ephantsi, amandla okungena anamandla, umgama omde wonxibelelwano, kodwa amandla okuthintela ukuphazamiseka, i-eriyali enkulu kunye namandla. Ukusetyenziswa okuphezulu; iimveliso usebenzisa itekhnoloji yonxibelelwano yeZeggbe engenazingcingo inamandla onxibelelwano lweenkwenkwezi; I-Wifi engenazingcingo ayisetyenziswa kancinci kwindawo yesicelo sompu, kwaye isetyenziswa ngakumbi kumqokeleli, ngoko ke andizukuyazisa ngokweenkcukacha apha.
Ngokusebenzisa olu lwazi lungentla, sinokuqonda ngokucacileyo ezinye iindlela zonxibelelwano zeskena sebhakhowudi eqhelekileyo, kwaye sinikeze ireferensi yokukhetha imveliso yebarcode efanelekileyo yeskena kwinqanaba lamva. Ukufunda ngakumbi malunga neskena sebhakhowudi, wamkelekile kuQhagamshelana nathi!Email：admin@minj.cn
