Amakhasimende amaningikungenzeka angazi indlela yokukhethaimodeli efanelelapho bonaThenga ibha ikhodi isithwebuli isibhamu. Wukuthi kungcono ukukhetha1D noma 2D? Futhi kuthiwani nge-wiredfuthi isithwebuli esingenantambo? Namuhla ake silungise umehluko phakathi kwezikena ze-1D neze-2D, futhi sikuncomele ukuthengisa okuhle kwemikhiqizo yesithwebuli emakethe.
1.Uyini umehluko phakathi kwezikena ze-1D ne-2D?
Skusho ukuthi ukhuluma,Iskena sebhakhodi ye-1D singaskena kuphela ibhakhodi ye-1D, isithwebuli sebhakhodi engu-2D singaskenakokubiliIbhakhodi ye-1D ne-2D. Futhi ngokwenani, intengo yesithwebuli sebhakhodi ye-1D izoba ishibhile kuneskena sebhakhodi ye-2D.
Kusukela ngo-1D isithwebuliayikwazi ukuskena2D ibhaikhodis, ngabe lokhu kusho ukuthiIsithwebuli se-2Dkuzoba ngcono kuneIskena se-1D? OHhayi cha,Iskena se-1D ube nenzuzo kufundaingibhakhodi ende uma kuqhathaniswa, ikakhulukazi njengamabhakhodi amade kumaphasela okusebenza. Ngenkathi isithwebuli se-2D sifunda i-CMOS, eqhubekaisithombe esithathwe ukuhlaziya ibhakhodi,ngakho-ke ikhono layo lokuqopha alilihle njengeskena se-1D.
2.Izinhlobo zamakhodi e-1D
Kunezinhlobo eziningi zeAmabhakhodi we-1D, futhi kunezinhlelo zekhodi ezivamile ezingaphezu kwamashumi amabili, kanje.
I-Code39 (Ikhodi ejwayelekile engu-39), ikhodi ye-Codabar (ikhodi ye-Cudebar), ikhodi engu-25 (ikhodi ejwayelekile engu-25), ikhodi ye-Matrix25 (ikhodi ye-Matrix 25), ikhodi ye-UPC-A, ikhodi ye-UPC-E, ikhodi ye-ITF25 (ikhodi ye-Cross 25), EAN -13 ikhodi (EAN-13 ibhakhodi yempahla yamazwe ngamazwe), ikhodi ye-EAN-8 (i-EAN-8 ibhakhodi yempahla yamazwe ngamazwe), Ikhodi 11, Ikhodi 93, ikhodi ye-ISBN, Ikhodi yeposi yaseChina (okuhlukile kwekhodi ye-Matrix 25), ikhodi ye-MSI , ikhodi ye-ISSN, ikhodi ye-Code128 (ikhodi ye-Code128, okuhlanganisa nekhodi ye-EAN128), i-Code39 EMS (ikhodi ye-EMS ekhethekile engu-39).
3.Izinhlobo zamakhodi e-2D
I-International Association of Automatic Identification Manufacturers (AIM) kanye ne-American Standardization Association (ANSI) baqedele amazinga ophawu lwezinhlelo zekhodi ye-2D njenge-PDF417, QR Code, Code 49, Code 16K kanye ne-Code One.
Ucwaningo lwaseChina ku2Dikhodiubuchwepheshe baqala ngo-1993.We sisungule ezethu izindinganiso kazwelonke zekhodi ye-2D: ikhodi yegridi yegridi ye-2D (SJ/T 11349-2006) kanye nekhodi ye-matrix yekhodi engu-2D (SJ/T 11350-2006).
Ngokuvamile, i-2DIkhodi esivame ukuyisebenzisa ngokuvamile ibhekisela ku-QR Code,njengeIfomethi yekhodi ye-QR ye-Alipay, inkokhelo ye-WeChat, amathikithi esitimela, njll.
4.Iziphi izigaba zokuskena okungenantambo?
Ukuskena okungenantambongizingahlukaniswa zibeizinhlobo ezintathu:I-Bluetoothokungenantambo, 2.4Gokungenantambo, 433MHZokungenantambo.Umehluko omkhulu walezi zindlela ezintathu ezingenazintambo zimi kanje.
Ibanga lokudluliswa kwe-Bluetooth (obala): 5~15 amamitha, ikhompuyutha kanye nomakhalekhukhwini/iphedi/ithebhulethinge-Bluetooth ingasetshenziswa.
Ibanga lokudlulisela le-2.4G (ebaleni):50 amamitha ~ 100 amamitha, udinga yangaphandleI-USBumamukeli kukhompuyutha.
433MHZ ibanga yokudlulisela (ebaleni): 200 amamitha, kodwaabanyeamazwe alawula umsakazolokho akunjalokuvunyelwe ukusebenzisa i-433MHZ.
Ngokuvamile, uma isabelomali sanele, kunconywa ukuthi kubekwe kuqala izibhamu zeskena ezingenantambo. Izikena ezingenantambo aziboshiwe ngentambo, yona'kulula kakhulu futhi kuyashesha ukuyisebenzisa.
5.Isincomo somkhiqizo weskena sebhakhodi engenantambo
MJ2880,Isithwebuli sebhakhodi engenantambo ye-bluetooth engu-2D
--Sekela amakhodi ebha ye-1D ne-2D, nokusekela ukuskena kwesikrini kudivayisi yeselula
--Umthamo webhethri omkhulu 2000mah, ungahlala isikhathi eside ukusetshenziswa kwamahora angu-8 ngaphandle kwenkokhiso.
--Okubili kusetshenziswe njengesithwebuli esinezintambo nesingenantambo
--Imodi eqhubekayo, Imodi ye-Manual, imodi yenzwa ezenzakalelayo ozikhethela yona
--Imodi yokulayisha esheshayo nemodi yokusungula ngokuzikhethela

6.Isincomo somkhiqizo wesithwebuli sebhakhodi enentambo
Inzuzo yesithwebuli esinezintambo i-plug-and-play, asikho isidingo sokubhanqa noma ukufaka umshayeli. Ngaphezu kwalokho, isithwebuli esinezintambo sibiza kakhulu.
Okomthengisi ojwayelekilekanye nesitolo esikhulu, isithwebuli sekhodi yebha ye-2D esiphathwayo siyisinqumo esihle. Ngenxa yokuthi kubiza kancane, iskena kokubili amabhakhodi ezimpahla kanye nomakhalekhukhwiniamakhodi, it iqinile futhiukumelana nokushaqeka, ingama iwa ukusuka kumamitha ama-2 ukuphakama ukuya kukhonkolo.
Ezitolo ezinkulu, ezinxanxatheleni zezitolo nakwezinye izitolo ezinokugeleza kwethrafikhi ephezulu, lapho kudingeka khona isivinini sokuskena esisheshayo, ukunemba okuphezulu, ukusetshenziswa okulula,ipulatifomu yesithwebuli sekhodi yedeskithophukuyisinqumo esihle. Ipulatifomu yesithwebuli sedeskithophu incane engeke ithathe isikhala esiningi. Ngoba ingafakwa kudeskithophu, ungakhulula izandla zakho, futhi's ukonga umsebenzi. Ukuskena okuzenzakalelayo newindi elikhulu lokuskena, kusiza ukuzwa nokufunda ibhakhodi ngokushesha, ukuze kusheshiswe ukusebenza kahle nokuthuthukisa ukwaneliseka kwamakhasimende.
Uma unentshisekelo noma umbuzo ngesikhathi sokukhetha noma ukusetshenziswa kwanoma yisiphi isithwebuli sekhodi yebha, wamukelekile kuXhumana nathi! MINJCODEuzibophezele ocwaningweni nasekuthuthukisweni kwebhakhodiisithwebuliubuchwepheshe kanye nemishini yokufaka isicelo,inkampani yethu ineminyaka engu-14 yesipiliyoni sembonini emikhakheni yobungcweti, futhi iye yaqashelwa kakhulu iningi lamakhasimende!
