There ‘s a great way to choose a barcode scanner

I ngā tau tata nei, kua kitea e ngā toa hokohoko nui o te motu, ngā toa mekameka me ētahi atu umanga arumoni ngā painga nui o te arumoni.Pūnaha POSki te whakahaere umanga arumoni, ā, kua hangaia he pūnaha whatunga POS arumoni. Ka whakaurua te mātāpono hoahoa me te tāutanga o te pūnaha whatunga ki roto i ngā hautaka ahumahi. Ko te nuinga o tēnei pepa e matapaki ana me pēhea te whiriwhiri i tētahi o ngāngā matawai waehere paehei wāhanga kohikohi raraunga o mua o te pūnaha POS arumoni.

E toru ngā matawai waehere pae arumoni noa: te matawai waehere pae CCD, te matawai waehere pae taiaho me te matawai waehere pae taiaho koki.

1. Matawai waehere pae CCDKa whakamahia te mātāpono o te hononga hiko whakaahua (CCD) hei whakaahua i te tauira tānga waehere pae, kātahi ka wetewete. Ko ōna painga: kāore he pou, he motuka, he roa te ora mahi. He iti te utu.

I te wā e whiriwhiri ana i tētahiMatawai CCD, e rua ngā tawhā nui: Te hōhonutanga o te mara:

Nā te mea he rite te kaupapa whakaahua CCD ki te kāmera, ki te hiahia koe ki te whakanui ake i te hōhonutanga o te mara, me whakanui ake te arotahi, kia nui rawa ai te rōrahi o te CCD, kia kore ai e pai te whakahaere. Me ngāwari te pānui i te CCD pai, kaua e piri ki te waehere pae, kia taurite te rōrahi, kia ngāwari hoki te whakahaere.

Taumira: Ki te hiahia koe ki te whakapai ake i te taumira o te CCD, me whakanui ake e koe te waeine o te waeine whakaahua-tairongo i te ahua. Ko te CCD utu iti he rima pika te nuinga, he nui te pānui i te EAN, UPC me ētahi atu waehere arumoni, he uaua ki te mōhio ki ētahi atu waehere. Ko te CCD awhe-waenga he nui ake i te 1024 pika, ko ētahi tae atu ki te 2048pixe1, ka taea te wehewehe i te waeine whaiti o te waehere pae 0.1mm.

2. Tematawai waehere pae laserhe matawai rārangi kotahi e whakamahi ana i ngā ngongo taiaho e rua hei pūtake mārama. E rua ngā momo matua: he whakaata hurihuri me te whakaata wiri.

E whakamahi ana i tētahi mōtini tere-teitei hei akiaki i tētahi rōpū porotiti hei hurihuri, kia huri ai te rēhia kotahi-ira e tukuna ana e ngā ngongo e rua hei rārangi. Ka matawaihia tēnei rārangi rēhia ki te waehere pae tonu. Ka mimiti te nuinga o te rēhia e te waehere pae pango, ā, ka whakaatahia e te mā te nuinga o te rēhia. I taua wā anō, ka whakaatahia te mārama whakaata mā roto i te karāhe whatu i roto i te 'mīhini', ā, ka arotahi ki tētahi ngongo-toru-whakaahuahiko. E whakaatu ana ngā kitenga i roto i te rohe wā he iti te taumata o ngā ngongo-toru-whakaahuahiko i runga i te whitiki pango waehere pae, ā, he teitei i runga i te whitiki mā. Whai muri i ētahi whakanui, ka hangaia he ngaru tapawhā, ā, ka rite te ngaru tapawhā ki te waehere pae kua matawaihia. Ka tukuna te āhua ngaru kua whiwhi ki te kaiwhakakore mā te raina raraunga. Ko te 'Whakakore' he rorohiko iti maramara kotahi. Ko te nuinga o te wā e whakawhirinaki ana ki te aukati me te kaute maramara kotahi hei tuhi i te wā peke ngaru. Ka wetewetehia te rarangi kua kohia i te matawai e whai ake nei, i te matawai whakamuri rānei. Ko te nuinga o te wā e whakawhirinaki ana ki te ōwehenga wā o ēnei kaute hei wetewete i te waehere pae e rite ana. I roto i te whakamahinga mahi, he maha ngā momo waehere pae, me ngā miro takai koretake pērā i te mata mirumiru, nō reira me aro te wāhanga wetewete ki ētahi hapa, engari kāore e taea te whakaputa waehere hapa. I tēnei wā, ko te wetewete he mea wehea ki te 8-bit me te 32-bit, ko te painga o te 8-bit ko te utu, ko te 32-bit ko te tere. Kī tonu te mākete waehere pae taiaho i ngā tarakona, engari i whai i te puehu matawai ccd, kua maha ngā hekenga o ngā utu, engari he maha ngā kaihanga kaha o te whare, me āta whakaaro ngā kaihoko ki te waitohu, me te whiriwhiri i te mea e tika ana.

He iti iho te utu o te whakaata wiri i tērā o te whakaata hurihuri, engari ehara i te mea ngāwari te whakapai ake i te tere matawai mā tēnei mātāpono o te pū taiaho, ko te tikanga he 33 ngā wā ia hekona.

Ina whiriwhiria e ngā umanga arumoni tētahi o ngāngā matawai taiaho, he mea nui ake te aro ki te tere me te taumira o te matawai, ā, ehara te hōhonutanga o te mara i te mea matua. Nā te mea ka piki ake te hōhonutanga o te mara, ka tino heke te taumira. Me tere te matawai a te matawai taiaho ringaringa pai, me teitei hoki te taumira i roto i te hōhonutanga o te mara kua whakaritea.

3. Ko te matawai koki hematawai waehere paee whakahurihuri ana i te taiaho e tukuna ana e te taiaho taiaho, e ngā rārangi matawai maha rānei mā roto i te pūnaha whatu. Ko te kaupapa matua he whakaiti i te mahi o te whakahāngai i te waehere pae ina whakaurua e te kaiutuutu ngā raraunga waehere pae. Ko tētahi o ngā kōwhiringa me arotahi ki te tohatoha wāhi o te rārangi matawai:

1. He maha ngā rārangi whakarara i te taha kotahi

2. He maha ngā rārangi matawai e pā ana i te kotahi pūwāhi

3. Ko te tūponotanga o te whakamaoritanga o ia pūwāhi he rite tonu i roto i tētahi wāhi motuhake

Ko te matawai koki e tutuki ana i ngā āhuatanga e toru i runga ake nei me waiho hei tētahi o ngā tono whiriwhiri a te pakihi.

Mena he hiahia, he pātai rānei āu i te wā e whiriwhiri ana, e whakamahi ana rānei i tētahi tūranga, pāwhiritia te hononga i raro nei, tukua mai tō pātai ki tā mātou mēra mana.(admin@minj.cn)tika tonu!WAEHERE MINJ E whakapau kaha ana mātou ki te rangahau me te whakawhanake i te hangarau pou me ngā taputapu tono, e 14 tau te wheako o tā mātou kamupene i roto i ngā mara ngaio, ā, kua tino mōhiotia e te nuinga o ngā kiritaki!

Rautaki whiriwhiri kua arotahihia mō ngā horopaki arumoni

*Whakatauritehia te mahi a te taputapu ki te tauine pakihi

I ngā āhuatanga he pumau te haere o ngā kaihoko, pērā i ngā toa iti me ngā hūpāmakete hapori, ko ngā mea taketakeNgā matawai waehere CCDka taea te whakatutuki i ngā hiahia taketake. Me arotahi ēnei taputapu ki te roa me te mahi mono-ā-ringa hei whakaiti i ngā utu tiaki. Mō ngā taiao hokohoko nui pēnei i ngā hūpāmakete mekameka me ngā toa hokohoko nui,ngā matawai taiaho waehere paeMe whakarite kia nui ake i te 50 ngā matawai ia hekona e mau ana i ngā pūwetewete 32-moka i ngā hāora pīki, ā, mā tēnei ka whakaitihia te wā tatari a te kiritaki.

*Te whiriwhiri i te hangarau matawai i runga i ngā āhuatanga o te hua

Mō ngā mea e hiahiatia ana i ia rā me ngā takai papatahi me ngā paewaehere paerewa, he pai ngā matawai CCD me te taiaho. Heoi, mō ngā hua he takai mirumiru, he kita, he mata piko rānei kei roto i ngā takai (pērā i ngā mea whakapaipai me ngā inu pounamu), he pai ake te ātete o ngā matawai taiaho ki ngā pokanoa. Mō ngā taonga iti he paewaehere kua whakanohoia matapōkeretia (pērā i ngā pepa tuhituhi me ngā taputapu), ka taea e ngā matawai taiaho koki te whakapai ake i te pai o te mahi.

*Whakaarohia te hototahitanga o te pūnaha

Me hono pai ngā matawai arumoni ki ngā pūnaha POS. Nō reira, he mea nui kia whakaūhia ngā kawa atanga e tautokona ana (pēnei i te USB, i te RS232 rānei) i mua i te hoko hei whakarite i te tukutahitanga raraunga me te pūmanawa rēhita moni me ngā pūnaha whakahaere rawa. Hei tauira, ko ngā matawai waehere pae mai i ngā kaihanga pēnei i a MINJCODE e tautoko ana i te hototahitanga maha-pūnaha me te whanaketanga ritenga, kia pai ake ai te whakatutuki i ngā hiahia whanaketanga roa o ngā umanga arumoni.

Ngā Kaupapa Matua mō te Whakataurite i te Utu me te Kounga

I te wā e whiriwhiri ana i ngā taputapu arumoni, he mea nui kia whakaarohia ngā utu haumitanga tuatahi me ngā utu mō te wā roa. Tērā pea ka ara ake ngā raruraru pēnei i te whakaroa o te matawai me te nui o ngā reiti rahunga o ngā taputapu iti te utu, ā, ka piki ake ngā mate whakahaere; i tetahi atu taha, mā te whai rawa i ngā āhuatanga papai ka hua ake he moumou tahua. Nō reira, he mea pai kia whiriwhiria ngā waitohu e tuku ana i te whakamana 1-2 tau me ngā ratonga whakatika i te wāhi, ko ngā hua pai ake mai i ngā kaihanga rongonui kua whakamanahia e te CE me te FCC. Mā tēnei ka whakarite i te kounga me te whakaiti i ngā mōrearea tiaki. Hei tāpiri, i te wā e hoko nui ana, whakaarohia ngā kaupapa here whakahekenga rarawe a te kaihanga hei whakapai ake i ngā utu hoko.

Ko te kaupapa matua o te whiriwhiri i tētahi pakihimatawai waehere paekei roto i te "whakaurunga horopaki." Ko te tautuhi mārama i te auau tauwhitinga o tō pakihi, ngā āhuatanga hua, me ngā whakaritenga pūnaha he mea nui ki te kimi i te taurite i waenga i te mahi me te utu. Mā te whiriwhiri whai whakaaro i waenga i ngā taputapu CCD, laser, me te laser koki, ka taea e koe te wero i te mana o mua ki roto i tō pūnaha POS, ā, ka whakarei ake i te whai huatanga o te whakahaere pakihi whānui.
