Sisitimu yeEPC sisitimu yepamberi, yakazara uye yakaoma, zita rayo rakazara rinonzi Electronic Product Code. Tekinoroji yeEPC ine chinangwa chekuvaka "Internet of Things" kuburikidza nepuratifomu yeInternet, ichishandisa kuzivikanwa kwemafrekisheni eredhiyo(RFID), kutaurirana kwedata kusina waya nedzimwe tekinoroji kuti pave nekugovaniswa kwemashoko panguva chaiyo yezvinhu zvepasi rose. Chinangwa cheEPC ndechekugadza mwero wepasi rose uye wakavhurika wekuziva chigadzirwa chimwe nechimwe, uye kuona kuteverwa nekutevera chigadzirwa chimwe chete pasi rose, kuitira kuti zvinyatso vandudza nhanho yekutarisira cheni yekugovera uye kuderedza mari yekufambisa.
Muna 1999, purofesa ane hunyanzvi paMassachusetts Institute of Technology akakurudzira pfungwa yeEPC open network, iyo yakabudirira kushandiswa muInternational Barcode Organization (EAN.UCC), Procter & Gamble (P&G), Coca-Cola, Wal-Mart, FedEx, Nestle, British Telecom SUN, PHILIPS, Nerutsigiro rwemakambani epasi rose makumi masere nematatu akadai seIBM, chirongwa ichi chekuvandudza chakatangwa. Musi wa1 Mbudzi 2003, International Article Numbering Association (EAN-UCC) yakatora zviri pamutemo kusimudzirwa kwepasi rose nekushandiswa kweEPC ndokutanga Electronic Product Code Global Promotion Center (EPC Global), zvichiratidza kuti EPC yapinda zviri pamutemo padanho rekusimudzira nekushandisa pasi rose. Panguva iyoyo, nyika dzakabudirira dzakadai seEurope, United States, neJapan dzese dzakaedza nepese padzinogona kukurudzira kushandiswa kwema electronic tag anoenderana netekinoroji yeEPC. China Article Numbering Center (ANCC) ndiyo yega kambani ine mvumo yekumiririra EPC Global muChina.
Magadzirirwo eEPC Internet of Things anofanirwa kunge aine maEPC codes, EPC tags uye RFID readers, middleware systems, object name resolution (ONS) servers, uye EPC information services kuti Internet of Things isvike pasi rose. Makodhi eEPCvane kugona kwakakwana kwekunyora makodhi, kubva pahuwandu hwevanhu vose pasi rose kusvika kuhuwandu hwese hwezviyo zvemupunga pasi rose, makodhi eEPC ane nzvimbo yakakwana yekuziva zvinhu izvi zvese. Kuti ive nechokwadi chekuti makodhi eEPC akasiyana, EPC Global inopa makodhi eEPC enyika kuburikidza nemasangano epasi rose ekunyora makodhi uye inogadza masisitimu ekutonga anoenderana nawo.
Kodhi yeEPC inoumbwa nenhamba yeshanduro, manejimendi yemazita echigadzirwa, chikamu chekupatsanura chigadzirwa uye nhamba yeserial. Parizvino, mhando dzekunyora dzinoshandiswa muEPC system dzinosanganisira 64-bit, 96-bit uye 256-bit. Semuenzaniso, kodhi ye96-bit EPC inogona kupihwa kumakambani anosvika mamiriyoni mazana maviri nemakumi matanhatu nemasere, imwe neimwe iine zvikamu zvechigadzirwa zvemamiriyoni gumi nematanhatu uye makodhi echigadzirwa ega ega ega emamiriyoni makumi matanhatu nemasere pachikamu chimwe nechimwe. Makodhi e96-byte angangove ari iwo anonyanya kushandiswa, sezvo achizadzisa zvinodiwa nedata uye anodhura zvine mwero.
Ndeipi mitemo inofanira kuteverwa neEPC?
EPC inofanira kutevedzera mitemo inotevera:
1. Yakazara, yakavhurika uye isina kwayakarerekera.
2. Hapana mari yehumambo maererano nekodzero dzepfuma yepfungwa.
3.Ma tag eRFIDuye vaverengi vane mutengo wakaderera uye mashandiro epamusoro.
4. Chengeta Chiratidzo cheRFIDzviri nyore sezvinobvira uye chengetedza ruzivo rweID mu network.
Kodhi yeEPC yakakamurwa kuita zvikamu zvina, ine nhamba dzakatevedzana, dzinogona kuziva mugadziri, chigadzirwa, tsananguro, uye nhamba yeserial yechinhu chakati. EPC ndiyo chete ruzivo rwakachengetwa muRFID tag, iyo inogona kuchengetedza mutengo wakaderera weRFID tag, uye huwandu husina muganho hwedata rinoshanduka hunogona kuita kuti tag ive nekuchinjika kukuru. Kuwedzera pakukwanisa kwayo kuziva zvinhu nemakodhi epasi rose, inogona zvakare kupa rumwe ruzivo nezvezvigadzirwa kuburikidza nenetwork yekodhi yechigadzirwa chemagetsi, senge kwakabva, nhoroondo yechigadzirwa, nezvimwewo. Idzi data dzinoita basa guru mukutevera nhoroondo yezvigadzirwa zvakati muketani yekugovera.
Nanning XGSun ine ruzivo rwemakore gumi nemana muindasitiri yeRFID, uye iri panzvimbo yekupa masevhisi ekugadzira ma tag eRFID inopa masevhisi ehunyanzvi eODM neOEM kune vatengi vepasi rose. Zvigadzirwa zvedu zvikuru zvinosanganisira ma RFID tags, Ma RFID hangtag, mavara emachira uye mavara ekudzivirira simbi. Uye vanokupai mabasa ekudhinda nekunyora makodhi. Kana muchida izvi, ndapota taurai nesu nekukurumidza.
