Dongosolo la EPC ndi dongosolo lapamwamba kwambiri, lokwanira komanso lovuta, lomwe dzina lake lonse ndi Electronic Product Code. Ukadaulo wa EPC cholinga chake ndi kupanga "Intaneti ya Zinthu" kudzera pa nsanja ya intaneti, pogwiritsa ntchito kuzindikira mafunde a wailesi(RFID), kulankhulana kwa data opanda zingwe ndi ukadaulo wina kuti tikwaniritse kugawana chidziwitso cha zinthu zapadziko lonse lapansi nthawi yeniyeni. Cholinga cha EPC ndikukhazikitsa muyezo wapadziko lonse lapansi komanso wotseguka wozindikiritsa chinthu chilichonse, ndikuzindikira kutsata ndi kutsatira chinthu chimodzi padziko lonse lapansi, kuti tiwongolere bwino momwe kayendetsedwe ka zinthu zoperekera katundu ndikuchepetsa ndalama zoyendetsera zinthu.
Mu 1999, pulofesa waluso ku Massachusetts Institute of Technology adapereka lingaliro la netiweki yotseguka ya EPC, yomwe idakhazikitsidwa bwino mu International Barcode Organisation (EAN.UCC), Procter & Gamble (P&G), Coca-Cola, Wal-Mart, FedEx, Nestle, British Telecom SUN, PHILIPS, Mothandizidwa ndi makampani 83 apadziko lonse lapansi monga IBM, dongosololi lidayambitsidwa. Pa Novembala 1, 2003, International Article Numbering Association (EAN-UCC) idatenga mwalamulo kutsatsa ndi kugwiritsa ntchito kwa EPC padziko lonse lapansi ndikukhazikitsa Electronic Product Code Global Promotion Center (EPC Global), posonyeza kuti EPC yalowa mwalamulo pagawo la kutsatsa ndi kugwiritsa ntchito padziko lonse lapansi. Panthawiyo, mayiko otukuka monga Europe, United States, ndi Japan onse adayesetsa kulimbikitsa kugwiritsa ntchito ma tag amagetsi omwe amagwirizana ndi ukadaulo wa EPC. China Article Numbering Center (ANCC) ndiye bungwe lokhalo lovomerezeka la EPC Global ku China.
Kapangidwe ka EPC Internet of Things kayenera kukhala ndi ma code a EPC, ma tag a EPC ndi owerenga a RFID, makina a middleware, ma seva a Object name resolution (ONS), ndi mautumiki azidziwitso a EPC kuti akwaniritse intaneti yapadziko lonse lapansi ya Zinthu. Makhodi a EPCali ndi mphamvu zokwanira zolembera ma code, kuyambira chiwerengero chonse cha anthu padziko lonse lapansi mpaka chiwerengero chonse cha mpunga padziko lonse lapansi, ma code a EPC ali ndi malo okwanira ozindikiritsa zinthu zonsezi. Pofuna kutsimikizira kuti ma code a EPC ndi apadera, EPC Global imapatsa ma code a EPC adziko lonse kudzera m'mabungwe apadziko lonse lapansi olembera ma code ndikukhazikitsa njira zoyendetsera zoyenera.
Khodi ya EPC imapangidwa ndi nambala ya mtundu, kasamalidwe ka dzina la domain la malonda, gawo la gulu la malonda ndi nambala yotsatizana. Pakadali pano, mitundu ya ma encoding omwe amagwiritsidwa ntchito mu dongosolo la EPC makamaka ndi 64-bit, 96-bit ndi 256-bit. Mwachitsanzo, khodi ya EPC ya 96-bit ikhoza kuperekedwa ku makampani 268 miliyoni, iliyonse ili ndi magulu 16 miliyoni azinthu ndi ma code 68 biliyoni azinthu payokha pagulu lililonse. Ma code a 96-byte mwina ndi omwe amatha kugwiritsidwa ntchito kwambiri, chifukwa amakwaniritsa zosowa za deta ndipo ndi okwera mtengo pang'ono.
Kodi EPC iyenera kutsatira malamulo ati?
EPC iyenera kutsatira mfundo izi:
1. Yonse, yotseguka komanso yopanda tsankho.
2. Ufulu wa chuma pankhani ya ufulu wa nzeru.
3.Ma tag a RFIDndi owerenga omwe ali ndi mtengo wotsika komanso magwiridwe antchito apamwamba.
4. Sungani Chizindikiro cha RFIDzosavuta momwe zingathere ndikusunga chidziwitso cha ID mu netiweki.
Khodi ya EPC yagawidwa m'magawo anayi, yokhala ndi manambala angapo, omwe amatha kuzindikira wopanga, chinthu, tanthauzo, ndi nambala yotsatizana ya chinthu china. EPC ndiye chidziwitso chokhacho chomwe chimasungidwa mu RFID tag, chomwe chingasunge mtengo wotsika wa RFID tag, ndipo kuchuluka kosatha kwa deta yosinthika kungapangitse tag kukhala yosinthasintha kwambiri. Kuphatikiza pa kuthekera kwake kuzindikira zinthu ndi ma code apadziko lonse lapansi, ingaperekenso zambiri zowonjezera za zinthu kudzera mu netiweki yama code yazinthu zamagetsi, monga chiyambi, mbiri yazinthu, ndi zina zotero. Deta iyi imagwira ntchito yofunika kwambiri pakutsata mbiri yazinthu zinazake mu unyolo woperekera.
Nanning XGSun ali ndi zaka 14 zokumana nazo mumakampani a RFID, ndipo ali paudindo wopereka chithandizo chopanga ma tag a RFID omwe amapereka ntchito zaukadaulo za ODM ndi OEM kwa makasitomala apadziko lonse lapansi. Zogulitsa zathu zazikulu zimaphatikizapo ma tag a RFID, Ma hangtag a RFID, zilembo za nsalu ndi zilembo zotsutsana ndi zitsulo. Ndipo timakupatsani ntchito zosindikiza ndi kulemba ma code. Ngati mukufuna izi, chonde titumizireni uthenga mwachangu momwe mungathere.
