Ngokuvamile, isithwebuli sebhakhodi singahlukaniswa sibe izigaba ezimbili: isithwebuli sebhakhodi enentambo nesithwebuli sebhakhodi engenantambo ngokuya ngohlobo lokudlulisela.
Iskena sebhakhodi enentambo ngokuvamile sisebenzisa intambo ukuxhumaumfundi webhakhodikanye nedivayisi yekhompyutha ephezulu yokuxhumana kwedatha.Ngokusho kwezinqubo zokuxhumana ezihlukene, ngokuvamile zingahlukaniswa zibe: isixhumi esibonakalayo se-USB, isixhumi esibonakalayo se-serial, isixhumi esibonakalayo sembobo yekhibhodi nezinye izinhlobo zokuhlangana.Idivayisi yebhakhodi engenantambo ingabuye ihlukaniswe izigaba ezilandelayo ngokuya nge-wireless transmission protocol: wireless 2.4G, Bluetooth,433Hz,zegbee, WiFi.Isithwebuli sebhakhodi enentambo esibonakalayo1.Isixhumi esibonakalayo se-USBIsixhumi esibonakalayo se-USB siyisixhumi esibonakalayo esisetshenziswa kakhulu kwizikena zebhakhodi, futhi ngokuvamile singasetshenziswa ezinhlelweni ze-Windows, i-MAC OS, i-Linux, i-Unix, i-Android nezinye izinhlelo.
Isixhumi esibonakalayo se-USB ngokuvamile singasekela izindlela ezintathu zokuxhumana zephrothokholi ezilandelayo.I-USB-KBW: Imbobo yekhibhodi ye-USB, efana nendlela yokusebenzisa ikhibhodi ye-USB, iyindlela yokuxhumana esetshenziswa kakhulu, ipulaki nokudlala, ayidingi ukufaka abashayeli. , futhi ayisekeli isilawuli sokucupha umyalo.Ngokuvamile sebenzisa i-Notepad, WORD, notepad++ namanye amathuluzi okukhipha umbhalo ukuze uhlole.I-USB-COM: Imbobo ye-serial ebonakalayo ye-USB (Imbobo ye-Virtual Serial).Uma usebenzisa lesi sikhombimsebenzisi sokuxhumana, ngokuvamile kuyadingeka ukuthi ufake umshayeli wembobo ye-virtual serial.Nakuba kusetshenziswa isixhumi esibonakalayo se-USB, iwukuxhumana kwembobo ye-analog, engasekela ukulawulwa kokuqalisa umyalo, futhi ngokuvamile kudingeka kusetshenziswe.Ukuhlola ithuluzi lembobo ewuchungechunge, okufana nomsizi wokulungisa iphutha wembobo ye-serial njll.I-USB-HID: Eyaziwa nangokuthi i-HID-POS, iyiphrothokholi yokudlulisa i-USB enesivinini esikhulu.Ayidingi ukufaka abashayeli.Ngokuvamile idinga ukuthuthukisa isofthiwe yokwamukela efanayo yokusebenzisana kwedatha futhi ingasekela ukulawula kokucupha umyalo.
2.Imbobo ye-serialI-serial port interface ibizwa nangokuthi ukuxhumana kwe-serial noma i-serial communication interface (evame ukubizwa ngokuthi isixhumi esibonakalayo se-COM).Ngokuvamile isetshenziswa kabanzi emkhakheni wezimboni.Inezici zebanga elide lokudlulisela, ukuxhumana okuzinzile nokuthembekile, futhi akuxhomekile ezinhlelweni eziyinkimbinkimbi.Izindlela zokusebenzelana kwayo zihlukahlukene Izinhlobonhlobo, njengolayini we-DuPont, ulayini wetheminali ongu-1.25, ulayini wetheminali ongu-2.0, ulayini wetheminali ongu-2.54, njll. Njengamanje, isithwebuli sivamise ukusebenzisa isignali yezinga le-TTL nokuphuma kwesignali ye-RS232, futhi isixhumi esibonakalayo esibonakalayo ngokuvamile singu-9- pin serial port (DB9).Uma usebenzisa imbobo ye-serial, udinga ukunaka iphrothokholi yokuxhumana (inombolo yembobo, i-parity bit, i-data bit, i-stop bit, njll.).Isibonelo, iphrothokholi yembobo yomkhiqizo evame ukusetshenziswa: 9600, N, 8, 1.TTL interface: I-TTL interface iwuhlobo lwembobo ye-serial, futhi okukhiphayo kuyisignali yeleveli.Uma ixhunywe ngqo kukhompuyutha, okuphumayo kuyavaleka.I-TTL ingaba ukuxhumana kwe-RS232 ngokungeza i-serial port chip (efana ne-SP232, MAX3232).Lolu hlobo lwesixhumi esibonakalayo luvame ukusetshenziselwa ukuxhuma i-single-chip microcomputer.Ngokuvamile sebenzisa ulayini we-DuPont noma ulayini wetheminali ukuze uxhume ngokuqondile i-VCC ehambisanayo, GND, TX, RX izikhonkwane ezine ukuze uxhumane.I-Support command trigger.Isixhumi esibonakalayo se-RS232: I-interface ye-RS232, eyaziwa nangokuthi imbobo ye-COM, iyimbobo ye-serial evamile, ngokuvamile engaxhunywa ngokuqondile emishinini yekhompyutha.Uma isetshenziswa, amathuluzi embobo yomkhiqizo ayadingeka ekukhipheni okuvamile, okufana nomsizi wokulungisa iphutha wembobo, itheminali ye-hyper namanye amathuluzi.Asikho isidingo sokufaka umshayeli.Ukusekela umyalo trigger.
3.Isixhumi esibonakalayo sembobo yekhibhodiIsixhumi esibonakalayo sembobo yekhibhodi sibuye sibizwe nge-PS/2 esibonakalayo, isixhumi esibonakalayo se-KBW (Keyboard Wedge), iyisixhumi esibonakalayo esiyindilinga esingu-6-pin, indlela yokuxhumana esetshenziswa kumakhibhodi okuqala, okwamanje asetshenziswa kancane, intambo yembobo yekhibhodi yebhakhodi ngokuvamile ezintathu Kunezixhumi ezimbili, eyodwa ixhunywe kudivayisi yebhakhodi, enye ixhunywe kwikhibhodi yekhompiyutha kanti enye ixhunywe kukhompyutha yokusingatha.Ngokuvamile sebenzisa okukhipha umbhalo kukhompuyutha, ipulaki futhi udlale.
4. ezinye izinhlobo zezindawo zokusebenzelanaNgaphezu kwalezi zindawo ezinezintambo ezingenhla, ibhakhodi izosebenzisa ezinye izinhlobo zezindlela zokuxhumana, njengokuxhumana kwe-Wiegand, ukuxhumana kwe-485, ukuxhumana kwembobo yenethiwekhi ye-TCP/IP nokunye.Lezi zindlela zokuxhumana ngokuvamile azisetshenziswa kakhulu, ngokuvamile ngokusekelwe endleleni yokuxhumana ye-TTL kanye nemojula yokuguqula ehambisanayo ingenziwa, futhi ngeke ngizethule ngokuningiliziwe lapha.I-Wireless Barcode Scanner Communication Interface1.
I-wireless 2.4GHz2.4GHz isho ibhendi yefrikhwensi yokusebenza.
1.2.4GHzI-ISM (Industry Science Medicine) iyibhendi yefrikhwensi engenantambo esetshenziswa esidlangalaleni emhlabeni.Ubuchwepheshe be-Bluetooth busebenza kule bhendi yefrikhwensi.Ukusebenza kubhendi yefrikhwensi engu-2.4GHz kungathola ububanzi obukhulu bokusetshenziswa.Futhi ikhono eliqinile lokulwa nokuphazamiseka, okwamanje elisetshenziswa kabanzi emikhakheni yasekhaya neyezohwebo.Ubuchwepheshe obusetshenziselwa ukudlulisa okungenazintambo nokuqhutshwa kwebanga elifushane.Iphrothokholi yokuxhumana engenantambo ye-2.4G inezinhlobonhlobo zezinhlelo zokusebenza, futhi inezinzuzo zesivinini sokudlulisa ngokushesha, ukusetshenziswa kwamandla okuphansi, ukubhanqa okulula, njll. Isithwebuli sebhakhodi ye-2.4G engenazintambo ngokuvamile ibanga lokudlulisela ngaphandle elingamamitha ayi-100-200, futhi liyisithwebuli sebhakhodi esisetshenziswa kakhulu.Indlela yokuxhumana engenantambo., Kodwa ngenxa yokuthi ubude begagasi be-2.4G bufushane futhi amandla okungena okuvama okuphezulu abuthakathaka, ibanga elijwayelekile lokudlulisela ngaphakathi endlini lingafinyelela kumamitha ayi-10-30 kuphela.Izifundi zebhakhodi ze-2.4G ezingenantambo ngokuvamile zidinga ukuhlonyiswa yisamukeli esingu-2.4G esixhunywe kumsingathi wedivayisi ukuze kudluliselwe idatha.
2. I-Bluetooth engenantambo I-BluetoothIbhendi ye-Bluetooth ingu-2400-2483.5MHz (kuhlanganisa nebhendi yonogada).Lena ibhendi yerediyo yebanga elifushane engu-2.4 GHz yebhendi yezimboni, ezesayensi, nezokwelapha (ISM) engadingi ilayisense (kodwa engalawulwa) emhlabeni wonke.I-Bluetooth isebenzisa ubuchwepheshe be-frequency hopping ukuze ihlukanise idatha edlulisiwe ibe amaphakethe edatha, asakazwa ngokulandelana ngamashaneli e-Bluetooth angama-79.Umkhawulokudonsa wesiteshi ngasinye ngu-1 MHz.I-Bluetooth 4.0 isebenzisa isikhala esingu-2 MHz futhi ingamukela iziteshi ezingama-40.Isiteshi sokuqala siqala ku-2402 MHz, isiteshi esisodwa nge-1 MHz, futhi siphela ku-2480 MHz.Ngomsebenzi we-Adaptive Frequency-Hopping (AFH), ngokuvamile igxuma izikhathi ezingu-1600 ngomzuzwana.Isifundi sebhakhodi ye-Bluetooth engenantambo sinesici esibaluleke kakhulu.Ingaxhunywa ocingweni olunohlelo lwe-Bluetooth ngezindlela eziningi zokuxhumana (njenge-HID, SPP, BLE), futhi ingaxhunywa kwikhompyutha ngaphandle kokusebenza kwe-Bluetooth kusetshenziswa isamukeli se-Bluetooth.Kulula ukuyisebenzisa.Abafundi bebhakhodi ye-Bluetooth engenantambo ngokuvamile basebenzisa imodi ye-Bluetooth enamandla aphansi ye-Class2, enamandla aphansi, kodwa ibanga lokudlulisela lifushane, futhi ibanga lokudlulisela elijwayelekile lingamamitha ayi-10. Kukhona ezinye izindlela zokuxhumana okungenantambo njenge433MHz, Zeggbe, Wifi nezinye izindlela zokuxhumana okungenantambo.Izici ze-wireless 433MHz ubude begagasi ende, imvamisa ephansi, amandla okungena aqinile, ibanga elide lokuxhumana, kodwa ikhono elibuthakathaka lokulwa nokuphazamiseka, i-antenna enkulu, namandla.Ukusetshenziswa okuphezulu;imikhiqizo esebenzisa ubuchwepheshe bezokuxhumana obungenawaya be-Zeggbe inekhono lokuxhumanisa inkanyezi;I-Wifi engenantambo isetshenziswa kancane kunkambu yokuskena isibhamu, futhi isetshenziswa kakhulu kusiqoqi, ngakho-ke ngeke ngiyethule ngokuningiliziwe lapha.
Ngolwazi olungenhla, singaziqonda ngokucacile ezinye izindlela zokuxhumana zesikena sebhakhodi esivamile, futhi sinikeze ireferensi yokukhetha umkhiqizo ofanele wesithwebuli sebhakhodi esigabeni sakamuva.Ukuze ufunde kabanzi mayelana nesithwebuli sebhakhodi, wamukelekile kuXhumana nathi!Email：admin@minj.cn
