RFID ndi ma bar code onse ndi matekinoloje onyamula deta omwe amasunga zambiri zama tag, koma ali ndi ntchito zosiyana kwambiri.Ndiye mumasiyanitsa bwanji ndikusankha pakati pa zilembo ziwirizi ndi zida zojambulira?
Choyamba, pali kusiyana kotani pakati pa RFID ndi bar code?
1. Ntchito zosiyanasiyana
Bar code ndi makina owerengeka kachidindo, m'lifupi mwa mipiringidzo yambiri yakuda ndi danga loyera, malinga ndi malamulo ena olembera, omwe amagwiritsidwa ntchito pofotokozera gulu la chidziwitso chojambula zithunzi.Khodi wamba wamba ndi mizere yofananira yokonzedwa ndi mipiringidzo yakuda (yotchedwa mipiringidzo) ndi mipiringidzo yoyera (yotchedwa yopanda kanthu) yokhala ndi mawonekedwe osiyana kwambiri.Pamene wowerenga bar code, foni yamakono kapena ngakhale chosindikizira apakompyuta akasanthula bar code, amatha kuzindikira zambiri za chinthucho.Ma barcode awa amatha kubwera mosiyanasiyana komanso kukula kwake, ndipo zomwe amazindikira sizikhudzidwa ndi mawonekedwe ndi kukula kwa barcode.
RFID ndi kulumikizana kwa data kosalumikizana pakati pa owerenga ndi tag kuti akwaniritse zomwe mukufuna ukadaulo wozindikiritsa ma radio frequency.Ma tag a Radio Frequency Identification (RFID) amakhala ndi tinthu tating'onoting'ono ndi tinyanga tawayilesi zomwe zimasunga deta yapaderadera ndikuzitumiza kwa owerenga RFID.Amagwiritsa ntchito minda yamagetsi kuti azindikire ndikutsata zinthu.Ma tag a RFID amabwera m'mitundu iwiri, yogwira ntchito komanso yongokhala.Ma tag omwe ali ndi mphamvu yawoyawo kuti atumize deta yawo.Mosiyana ndi ma tag okhazikika, ma tag ongokhala amafunikira owerenga omwe ali pafupi kuti atulutse mafunde a electromagnetic ndikulandila mphamvu zamafunde amagetsi kuti atsegule ma tag, kenako ma tag okhazikika amatha kusamutsa zomwe zasungidwa kwa owerenga.
2. Ntchito zosiyanasiyana
RFID ili ndi ntchito zambiri.Pakali pano, ntchito monga nyama Chip, galimoto Chip wakuba Alamu, mwayi mwayi, kulamulira malo magalimoto, kupanga mzere zochita zokha, kasamalidwe zinthu, katundu chodetsa, etc. Barcodes akhoza chizindikiro dziko kupanga, Mlengi, dzina la katundu tsiku la kupanga, nambala yamagulu a mabuku, malo oyambira ndi omalizira a makalata, gulu, tsiku ndi zina zambiri, kotero zimagwiritsidwa ntchito kwambiri m'madera ambiri, monga kufalitsa katundu, kasamalidwe ka library, kasamalidwe ka zinthu, mabanki. dongosolo ndi zina zotero.
3. Mfundo yogwira ntchito ndi yosiyana
Ukadaulo wozindikiritsa ma radio pafupipafupi kudzera pa mafunde a wailesi samalumikizana ndikusinthana kwazidziwitso mwachangu ndiukadaulo wosungirako, kudzera pakulankhulana opanda zingwe komanso ukadaulo wofikira pa data, kenako kulumikizidwa ndi kachitidwe ka database, kuti tikwaniritse kulumikizana kosalumikizana kwanjira ziwiri, kuti mukwaniritse cholingacho. ya chizindikiritso, yogwiritsidwa ntchito posinthanitsa deta, imapanga dongosolo lovuta kwambiri.Mu dongosolo lozindikira, kuwerenga, kulemba ndi kulumikizana kwa tag yamagetsi kumachitika ndi electromagnetic wave.
Ukadaulo wa Barcode umabadwa ndi chitukuko ndi kugwiritsa ntchito makompyuta ndiukadaulo wazidziwitso.Ndi ukadaulo watsopano womwe umaphatikiza ma code, kusindikiza, kuzindikira, kupeza deta ndi kukonza.
M'moyo weniweni, nthawi zambiri timatha kuwona ma bar code ndi ma tag a RFID muzotengera zosiyanasiyana zamitundu yosiyanasiyana, monga masitolo akuluakulu, malo ogulitsira, zofunika zatsiku ndi tsiku kuti muwone ma bar ma tag ochulukirapo, mu nsapato za zovala ndi zikwama ndi zinthu zina monga ma tag a RFID ambiri. , chifukwa chiyani izi zikuchitika?Choyamba tiyeni timvetsetse ubwino ndi kuipa kwa ma bar code ndi ma tag a RFID ndi zida zowerengera ndi kulemba.
Ubwino ndi Kuipa kwa Bar Codes
Ubwino:
1. Ma barcode ndiapadziko lonse lapansi komanso osavuta kugwiritsa ntchito, chifukwa masitolo okhala ndi ma barcode amatha kunyamula ma barcode ochokera kumalo ena.
2. Ma tag a bar code ndi owerenga ma bar code ndi otsika mtengo kuposa ma tag a RFID ndi owerenga.
3. Ma tag a bar code ndi ang'onoang'ono komanso opepuka kuposa ma tag a RFID.
Zoyipa:
1. Wowerenga bar code ali ndi mtunda waufupi wozindikirika ndipo uyenera kukhala pafupi ndi tag.
.
3. Zolemba zimasunga zocheperako.
4. Owerenga ma bar code ayenera kufufuzidwa payekhapayekha ndipo samathandizira kuwerenga kwamagulu, zomwe zimapangitsa kuti asamawerenge bwino.
5. Zolemba ndizosavuta kupangira, ndipo mtengo wopangira ndi wotsika.
Ubwino ndi Kuipa kwa RFID
Ubwino:
1.RFID tag ndi owerenga kuwerenga mtunda ndi kutali.
2. Ma tag angapo amatha kuwerengedwa panthawi, kuthamanga kwa data.
3. Chitetezo chachikulu cha data, kubisa, kusintha.
4.RFID tag ikhoza kutsimikizira kuti chinthucho ndi chowonadi ndipo chimakhala ndi ntchito yotsutsana ndi chinyengo ndi kufufuza.
5.RFID Tags pakompyuta zambiri kukhala ndi makhalidwe a madzi, antimagnetic, mkulu kutentha kukana, kuonetsetsa bata la ntchito luso wailesi pafupipafupi chizindikiritso.
Ukadaulo wa 6.RFID malinga ndi kompyuta ndi zidziwitso zina zosungira, mpaka ma megabytes angapo, zimatha kusunga zambiri, kuonetsetsa kuti ntchitoyo ikuyenda bwino.
Zoyipa:
1. Mtengo wa RFID tag ndi wowerenga ndi wapamwamba kuposa bar code.
2. Ma tag a RFID ndi owerenga ayenera kusankhidwa malinga ndi kuchuluka kwa kuwerenga, mtunda ndi chilengedwe, komanso zambiri za RFID ndi chidziwitso chaumisiri zimafunika kuti zitsimikizire kuti chiwerengero chowerengera chikukwaniritsidwa.
Zitha kuwoneka kuchokera pamwambapa kuti mawonekedwe a barcode, tag ya RFID ndi zida zothandizira kuwerenga ndi kulemba ndizosiyana, kotero makasitomala ayenera kusankha zinthu zoyenera malinga ndi zosowa zenizeni.
