Iskena sebhakhowudi sisixhobo esisetyenziselwa ukufunda ulwazi oluqulethwe kwibhakhowudi. Zingahlelwa njengezekena zebhakhowudi, i-omni-directional barcode scanners, i-handheld barcode scanners njalo njalo. Kukho kwakhonaIskena sebhakhowudi ye-1D kunye ne-2D. Isakhiwo somfundi webhakhowudi ngokuqhelekileyo siqulathe la macandelo alandelayo: umthombo wokukhanya, isixhobo sokufumana, izinto zokuguqula i-photoelectric, i-decoding circuit, i-computer interface. Umgaqo osisiseko wokusebenza weskena sebhakhowudi ngolu hlobo lulandelayo: ukukhanya okukhutshwa ngumthombo wokukhanya kuqondiswe ngenkqubo ye-optical kwisimboli yebhakhowudi. Ukukhanya okubonakalisiweyo kubonakaliswe kwi-converter ye-photoelectric ngokusebenzisa inkqubo ye-optical kwaye itolikwa yi-decoder njengophawu lwedijithali olunokwamkelwa ngokuthe ngqo kwikhompyutheni.
1. iskena se-omni-directional asikwazi ukufunda ibhakhowudi ngokuchanekileyo izizathu kunye nezisombululo
1.1Ingxaki yomthombo wokukhanya:
Umthombo wokukhanya ubaluleke kakhulu ekufundeni ibhakhowudi, kuba umthombo wokukhanya kufuneka unikeze ukukhanya okwaneleyo kunye nokufana ukuze kuqinisekiswe ukuba ibhakhowudi ibonakala ngokucacileyo. Ukuba ii-omni directional scannerinengxaki yomthombo wokukhanya, njengokungonelanga kwemvelaphi yokukhanya, unikezelo lomqadi olungalinganiyo, njl. njl., kuya kubangela ukuba iskena singakwazi ukufunda ibhakhowudi ngokuchanekileyo.
1.2 Ingxaki yoMgangatho:
Umgangatho webhakhowudi unempembelelo enkulu kwisiphumo sokuskena. Umzekelo, ukuba umbala webhakhowudi umnyama kakhulu okanye umboniso uphezulu kakhulu, kuya kuchaphazela isakhono sokuqaphela iskena. Ukongeza, umgangatho woshicilelo olambathayo, imfiliba okanye eyonakeleyo ibhakhowudi inokuchaphazela iziphumo zokuskena.
1.3 Ukuskena iingxaki zoyilo lwentloko:
Uyilo lweI-omni-directional bar code scannerintloko inokuba nengxaki yokunxaxha kwe-angular okanye isantya sokuskena esingazinzanga. Ukuba intloko yokuskena ayikwazi ukubamba ngokuchanekileyo iimpawu zebhakhowudi, okanye ukuba igqwethiwe okanye iphazamisekile ngexesha lentshukumo, iya kubangelaiskenaukusilela ukufunda ibhakhowudi ngokuchanekileyo.
1.4 Iingxaki ze-Software Algorithm.
I-algorithms yokuskena ibalulekile ekufundeni ikhowudi yebha. Ii-algorithms zesoftware kufuneka zixhase iintlobo ezahlukeneyo zebhakhowudi, zikwazi ukoyisa iziphumo zokukhanya okujikeleze, ukunciphisa izinga lekhowudi yobuxoki, kwaye ube nokukwazi ukwenza uchongo olukhawulezayo.
Ukuba unomdla okanye umbuzo ngexesha lokukhetha okanye ukusetyenziswa kwaso nasiphi na iskena sebhakhowudi, nceda Cofa ikhonkco elingezantsi thumela umbuzo wakho kwiposi yethu esemthethweni.(admin@minj.cn)ngqo!MINJCODE uzibophelele kuphando kunye nophuhliso lwetekhnoloji yesikena sebhakhowudi kunye nezixhobo zokusebenza, inkampani yethu ineminyaka eli-14 yamava oshishino kwiinkalo zobungcali, kwaye yamkelwa kakhulu luninzi lwabathengi!
2. Isisombululo
2.1 Kwingxaki yomthombo wokukhanya, uyilo lomthombo wokukhanya olunge ngakumbi lunokusetyenziswa ukuqinisekisa ukukhanya okwaneleyo kunye nokufana. Okwangoku, ngenxa yengxaki yoshicilelo lwebhakhowudi, umgangatho kunye nokuchaneka kwebhakhowudi yoshicilelo kunokuphuculwa ukuze kuqinisekiswe ukuba ibhakhowudi ibonakala ngokucacileyo. Ukuskena iingxaki zoyilo lwentloko, ukwakheka kwentloko yokuskena kunokuphuculwa ukuphucula ukunyamezela ukuphambuka kwe-angular kunye nokuzinza kwesantya sokuskena. Kwii-algorithms zesoftware, i-algorithms yokuskena inokuphuculwa ukuphucula ukuqondwa kweentlobo ezahlukeneyo zebhakhowudi kunye nokuchasana nokuphazamiseka kokukhanya okungqongileyo. Ukuba yingxaki yehardware, nceda uqhagamshelane nesiqinisekiso sobugcisa.
Abafundi bebhakhowudi ye-Omni-directionalzisetyenziswa kakhulu kumashishini ahlukeneyo, ngakumbi ukuthengisa, ukuhanjiswa kunye nokugcinwa kwempahla, kwaye ziphucule kakhulu ukusebenza kokuskena kunye nokuchaneka. Nangona kunjalo, izikena zebhakhowudi ze-omni-directional zisenengxaki yokungakwazi ukufunda iibhakhowudi ngokuchanekileyo, nto leyo ekwabubunzima obuqhelekileyo bobugcisa. Ngolwazi oluthe kratya lwemveliso kwi-omni-directional qr scanners, ncedaQhagamshelana nathi!
