Mu myaka yashize, amaduka manini yo mu gihugu, amaduka acururizwamo hamwe n’ibindi bigo by’ubucuruzi byabonye inyungu nini z’ubucuruziSisitemu ya POSkubucuruzi bwubucuruzi, kandi bubatse sisitemu yubucuruzi ya POS.Igishushanyo nogushiraho ihame rya sisitemu y'urusobe yatangijwe muburyo burambuye mubinyamakuru bitandukanye byinganda.Uru rupapuro ruvuga cyane cyane uburyo bwo guhitamo imwe muri scaneri yubucuruzi ya barcode nkigice cyambere cyo kubona amakuru igice cya sisitemu yubucuruzi POS.
Hano haribintu bitatu bisanzwe byubucuruzi bwa barcode: scaneri ya barcode ya CCD, scaneri ya laser barcode na angeri ya laser barcode scaneri.
1. CCD barcode scaneriikoresha ihame ryo gufotora amashanyarazi (CCD) kugirango ushushanye uburyo bwo gucapa barcode, hanyuma ukayitandukanya.Ibyiza byayo ni: nta shaft, moteri, ubuzima bwa serivisi ndende.Igiciro kirahendutse.
Iyo uhisemo scaneri imwe ya CCD, ibipimo bibiri byingenzi ni: Ubujyakuzimu bwumurima:
Kuberako ihame rya CCD ryerekana amashusho risa na kamera, niba ushaka kongera ubujyakuzimu bwumurima, guhuza lens bihuye, kuburyo amajwi ya CCD ari manini cyane, ntibyoroshye gukora.CCD nziza igomba gusomwa idatsimbaraye kuri kode yumurongo, hamwe nubunini buringaniye kandi ikora neza.
Umwanzuro: Niba ushaka kunoza imiterere ya CCD, ugomba kongera igice cyibintu bigize fotosensitif ku ishusho.CCD ihendutse muri rusange ni pigiseli eshanu, soma EAN, UPC nandi ma code yubucuruzi arahagije, kubindi kumenyekanisha kode bizagorana.Hagati ya CCD irenze pigiseli 1024, zimwe ndetse kugeza kuri 2048pixe1, irashobora gutandukanya ibice bigufi bya 0.1mm kode yumurongo.
2. Thelaser barcode scanerini umurongo umwe wa scaneri ukoresheje lazeri ebyiri nkisoko yumucyo.Ifite ahanini ubwoko bubiri: indorerwamo izenguruka hamwe nindorerwamo ya vibrato
Ikoresha moteri yihuta kugirango itware itsinda rya prism kuzunguruka, kuburyo laser point imwe yoherejwe na tebes ebyiri iba umurongo.Uyu murongo wa laser wasikishijwe kode yumurongo ubwayo.Akabari kode yumukara ikurura lazeri nyinshi, naho umweru ugaragaza byinshi bya laser.Muri icyo gihe, urumuri rwerekanwe rugaragarira mu cyuma cya optique muri 'moteri', kandi cyibanda ku mashanyarazi atatu.Indorerezi mugihe cyateganijwe zerekana ko fotoelectric eshatu-tube urwego ruto kurwego rwumukandara wumukandara, nurwego rwo hejuru kumukandara wera.Nyuma yo kwongerwaho byinshi, umuraba wurukiramende urakorwa, kandi urukiramende rwurukiramende ruhuye na kode ya skaneri.Imiterere yabonetse yoherejwe kuri decoder ikoresheje umurongo wamakuru.'Decoder' mubyukuri ni microcomputer imwe imwe.Biterwa ahanini no guhagarika hamwe na chip imwe kugirango yandike igihe cyo gusimbuka.Ikusanyirizo ryegeranijwe ryashizwe kumurongo ukurikira cyangwa gusikana inyuma.Biterwa ahanini nigihe cyo kugereranya kwi compte kugirango ucike kode yumurongo uhuye.Mubikorwa bifatika, hariho ubwoko bwinshi bwimyandikire yumurongo, hamwe nudukingirizo twa paki zidasanzwe nkubuso bwa bubble, bityo decoding igice ikenera kwihanganira amakosa, ariko ntishobora gutanga kode yamakosa.Kugeza ubu, decoder igabanijwemo 8 bit na 32 bit, inyungu 8 bit ni igiciro, 32 bit ni umuvuduko.Isoko rya code ya laser baruzuyemo ibiyoka, ariko kandi bikurikiza umukungugu wa ccd scaneri, ibiciro byagabanutse inshuro nyinshi, akazu, ariko hariho inganda nyinshi zikomeye zo murugo, abaguzi bakeneye gusuzuma neza ikirango, bagahitamo igikwiye.
Igiciro cyindorerwamo ihinda umushyitsi kiri munsi yicy'indorerwamo izunguruka, ariko iri hame ryimbunda ya laser ntabwo ryoroshye kunoza umuvuduko wo gusikana, mubisanzwe inshuro 33 kumasegonda.
Iyo ibigo byubucuruzi bihisemo imwe muri scaneri ya laser, ni ngombwa cyane kwitondera umuvuduko wo gusikana no gukemura, kandi ubujyakuzimu bwumurima ntabwo ari ikintu cyingenzi.Kuberako iyo ubujyakuzimu bwumurima bwiyongereye, imyanzuro izagabanuka cyane.Icyuma cyiza cya laser scaneri kigomba kugira umuvuduko mwinshi wo gusikana no gukemura neza murwego rwimbitse rwumurima.
3. Gusikana inguni ni ascaneri ya barcodeibyo bivanaho lazeri yoherejwe na diode ya laser cyangwa imirongo myinshi yo gusikana binyuze muri sisitemu ya optique.Intego nyamukuru nukugabanya imirimo yo guhuza kode yumurongo mugihe kashi yinjiye mumibare yamakuru.Imwe mumahitamo igomba kwibanda kumwanya wo gukwirakwiza umurongo wo gusikana:
1.Hariho imirongo myinshi ibangikanye muburyo bumwe
2. Imirongo myinshi yo gusikana inyura kumwanya umwe
3. Ibisobanuro byo gusobanura kuri buri ngingo bikunda kuba bihamye mumwanya runaka
Inguni ya scaneri ihuye ningingo eshatu zavuzwe haruguru igomba kuba imwe mubisabwa guhitamo ubucuruzi.
