Ngokubhekiselele kwi-wireless Radio Frequency Identification, amaza okusebenza aqhelekileyo aquka i-125KHZ, 13.56MHz, 869.5MHz, 915.3MHZ, 2.45GHz njl njl, ehambelana ne: frequency low (LF), high frequency (HF), ultra high frequency (UHF), imicrowave (MW) .Ithegi nganye yebhendi yefrikhwensi ineprotocol ehambelanayo: umzekelo, i-13.56MHZ ine-ISO15693, i-14443 protocol, kunye ne-ultra-high frequency (UHF) inemigangatho emibini yeprotocol yokukhetha.Enye yi-ISO18000-6B, kwaye enye yi-EPC C1G2 esemgangathweni eyamkelwe yi-ISO njenge-ISO18000-6C.
ISO18000-6B umgangatho
Iimpawu eziphambili zomgangatho zibandakanya: umgangatho ovuthiweyo, imveliso ezinzileyo, kunye nesicelo esibanzi;Inombolo yesazisi iyodwa ehlabathini;funda inombolo yesazisi kuqala, emva koko ufunde indawo yedatha;umthamo omkhulu we-1024bits okanye i-2048bits;indawo enkulu yedatha yomsebenzisi ye98Bytes okanye 216Bytes;iithegi ezininzi ngexesha elinye Funda, ukuya kuthi ga kwishumi leethegi ezinokufundwa ngexesha elinye;isantya sokufunda idatha yi-40kbps.
Ngokweempawu zomgangatho we-ISO18000-6B, ngokubhekiselele kwisantya sokufunda kunye nenani leebhile, iileyibhile ezisebenzisa umgangatho we-ISO18000-6B zinokuthi zihlangabezane neemfuno kwizicelo kunye nenani elincinci leelebhile ezifunekayo njenge-bayonet kunye nokusebenza kwe-dock.Iileyibhile ze-elektroniki ezithobela umgangatho we-ISO18000-6B zifanelekile ikakhulu kulawulo lolawulo oluvaliweyo, olunjengolawulo lwe-asethi, iilebhile zombane eziphuhliswe ekhaya zokuchongwa kweekhonteyina, iileyibhile zepleyiti yelayisensi ye-elektroniki, kunye neelayisensi zokuqhuba ze-elektroniki (amakhadi okuqhuba), njl.
Iintsilelo zomgangatho we-ISO18000-6B zezi: uphuhliso luye lwahamba kwiminyaka yamuva nje, kwaye lwatshintshwa yi-EPC C1G2 kwizicelo ezininzi;iteknoloji yokuphilisa isofthiwe yedatha yomsebenzisi ayivuthwanga, kodwa kulo mzekelo, idatha yomsebenzisi inokufakwa kwaye isonjululwe ngabavelisi be-chip kunye.
ISO18000-6C (EPC C1G2) umgangatho
Isivumelwano siquka ukudityaniswa kweClass1 Gen2 eqaliswe yiGlobal Product Code Centre (EPC Global) kunye ne-ISO/IEC18000-6 eqaliswe yi-ISO/IEC.Iimpawu zalo mgangatho zezi: isantya esikhawulezayo, izinga ledatha linokufikelela kwi-40kbps ~ 640kbps;inani leethegi ezinokufundwa ngaxeshanye likhulu, ngokwethiyori ngaphezu kwe-1000 iithegi zinokufundwa;funda kuqala inombolo ye-EPC, inombolo ye-ID yethegi kufuneka ifundwe kunye nedatha yeMode yokufunda;umsebenzi onamandla, iindlela ezininzi zokukhusela ukubhala, ukhuseleko oluqinileyo;iindawo ezininzi, ezahlulwe kwindawo ye-EPC (i-96bits okanye i-256bits, inokwandiswa kwi-512bits), indawo ye-ID (64bit okanye i-8Bytes), indawo yomsebenzisi (512bit okanye i-28Bytes)), indawo yephasiwedi (32bits okanye i-64bits), imisebenzi enamandla, iindlela ezininzi zokubethela , kunye nokhuseleko olomeleleyo;nangona kunjalo, iileyibhile ezinikezelwe ngabavelisi abathile abanazo iindawo zedatha yabasebenzisi, njengeeleyibhile ze-Impinj.
Ngenxa yokuba umgangatho we-EPC C1G2 uneenzuzo ezininzi ezifana nokuguquguquka okunamandla, ukuthotyelwa kwemithetho ye-EPC, ixabiso eliphantsi lemveliso, kunye nokuhambelana okuhle.Ikakhulu ifanele ukuchongwa kwenani elikhulu lezinto kwinkalo yolungiselelo kwaye ikuphuhliso oluqhubekayo.Kungoku nje kumgangatho oqhelekileyo wezicelo ze-UHF RFID, kwaye isetyenziswa kakhulu ezincwadini, kwimpahla, kwiivenkile ezithengisayo nakwamanye amashishini.
Le migangatho mibini ineenzuzo zayo.Xa usenza iprojekthi yokudibanisa, kufuneka uqhathanise ngokwendlela yakho yesicelo ukukhetha umgangatho ofanelekileyo.
