Imvelaphi kunye nesicelo
Ubungakanani bemarike ye-logistics yehlabathi bukhula rhoqo, kodwa kukho iingxaki ezininzi kwimodeli yendabuko ye-logistics. Umzekelo: Ukuthembela kwimisebenzi yesandla kunokubangela ukuba iimpahla zingafiki ngexesha okanye zingaphoswanga zibalwe. Kwangaxeshanye, kuthatha ixesha elide ukungena nokuphuma kwindawo yokugcina impahla, ukuhamba kweemveliso kuhamba kancinci, kwaye kunzima ukwenza ukurekhoda kunye nokulungiselela idatha yemveliso kube semgangathweni. Ukusebenzisa itekhnoloji ye-RFID kwinkqubo ye-supply chain, kunye nokusetyenziswa kweenkqubo zesoftware ezinxulumene noko ezifana ne-Manufacturing Execution System, i-Warehouse Management System kunye ne-Logistics Execution System, kunokusombulula ezi ngxaki kwaye kuhlangatyezwane neemfuno ze-supply chain. Ingaqonda ukulandeleka kweemveliso ukusuka kwimveliso, ukugcina impahla, ukuthutha, ukusasazwa, ukuya kuthengiso, kwanokubuyisela izinto. Ayinakuphucula kuphela kakhulu i-automation ye-supply chain yonke, kodwa ikwanciphisa kakhulu izinga leempazamo. Ukuphucula inqanaba lobukrelekrele kuye kwaba yinxalenye ebalulekileyo yophuhliso lwe-logistics yanamhlanje kunye ne-supply chain.
1. Ikhonkco leMveliso
Imveliso nganye incamathiselwe nge Ithegi ye-UHF engasebenziyo ye-rfid ngedatha efanelekileyo ebhaliweyo kuyo, kwaye abafundi beRFID banamathele kwiikhonkco ezininzi ezibalulekileyo zomgca wemveliso. Xa iimveliso ezine-UHF passive rfid tag zidlula kwi-fixed RFID reader ngokulandelelana, umfundi uya kufunda ulwazi lwelebheli kwimveliso aze alayishe idatha kwinkqubo ye-MES, aze emva koko agwebe imeko yokugqitywa kweemveliso kwimveliso kunye nemeko yokusebenza kwesikhululo ngasinye somsebenzi.
2. Ikhonkco lokugcina impahla
Qhoboshela izitikha zeRFID ezingasebenziyo zoluhlu oludeukuya kwindawo yeempahla kunye neepalethi kwindawo yokugcina impahla. Iithegi ezikrelekrele ziqulathe iinkcukacha zecandelo, iinombolo zeserial kunye nolunye ulwazi. Xa iimpahla zingena kwaye ziphuma kwindawo yokugcina impahla, abafundi beRFID abakwindawo yokungena kunye nokuphuma banokufunda ezi lebhile. Kwaye barekhode kwaye baqhubeke ngokuzenzekelayo. Abaphathi beWarehouse banokuqonda ngokukhawuleza ulwazi oluchanekileyo malunga nemeko yempahla ngenkqubo ye-WMS.
3. Ikhonkco lezoThutho
QhoboshelaIilebhile ze-RAIN UHF RFID kwiimpahla, kwaye ufake ii-RFID readers kwizikhululo zeebhasi, kwizikhululo zikaloliwe, kwiidokhi, kwizikhululo zeenqwelo-moya, kwiindawo zokuphuma kwiindlela ezinkulu, njl. Xa umfundi we-RFID efunda ulwazi lwelebheli, angathumela ulwazi lwendawo yeempahla kwiziko lokuthumela imithwalo ngexesha langempela. Ukuba ulwazi lwemithwalo (ubunzima, umthamo, ubungakanani) lufunyaniswe lungachanekanga, umfundi we-RFID unokuqhutywa ukuba afunde ithegi echaziweyo. Ukuba iimpahla azifumaneki emva kokukhangela okwesibini, umyalezo wesilumkiso uya kuthunyelwa kwiziko lokuthumela ukuthintela ukuba iimpahla zingalahleki okanye zibiwe.
4. Ikhonkco loSasazo
Xa iimpahla kunyeIilebhile zokuthumela zeRFIDXa zithunyelwa kwiziko lokuhambisa impahla, umfundi we-RFID uza kufunda ulwazi lwethegi kuzo zonke iimpahla ezikwipalethi yokuhambisa impahla. Inkqubo yesoftware efanelekileyo ithelekisa ulwazi lwethegi nolwazi lokuthumela impahla, ibona ngokuzenzekelayo ukungangqinelani kwayo, kwaye ithintele iimpazamo zokuhambisa impahla. Kwangaxeshanye, indawo yokugcina impahla kunye nemeko yokuhambisa impahla inokuhlaziywa. Fumanisa apho ukuhanjiswa kwakho kuvela kwaye kuya khona, kunye nexesha lokufika elilindelekileyo, nokunye okuninzi.
1.5 Ikhonkco lokuthengisa
Xa imveliso incamathiselwe kwi Ithegi yesitikha seRFID, ayipheleli nje ekubeni ixesha lokusebenza kwemveliso libekwe esweni ngenkqubo yesoftware efanelekileyo, kodwa isixhobo sokufunda i-RFID esifakwe kwikhawuntara yokuhlawula sinokusetyenziselwa ukuskena ngokuzenzekelayo kunye nokuhlawulisa imveliso, nto leyo ephucula kakhulu ukusebenza kakuhle kwemveliso. Inciphisa iindleko zomsebenzi kwaye iphucula nenqanaba lobukrelekrele.
Uhlalutyo loKhetho lweMveliso
Xa sikhetha imveliso, kufuneka siqwalasele ukuvumela kwento eza kuncamathiselwa, kunye nokuphazamiseka phakathi kwetshiphu kunye ne-antenna. Uninzi lweethegi ezisetyenziswa kushishino lwezothutho ngokubanzi zezi Iithegi zeRFID zezikhongozeli zokuthumela, ezincamatheliswe kwiibhokisi. Ukuze kuthintelwe ukuba izinto ezithuthwa kwiibhokisi zingonakali, iibhokisi zezothutho ngokubanzi aziyi kuvezwa kubushushu obugqithisileyo okanye kumswakama ixesha elide kwindawo esingqongileyo. Ukuba akukho mfuneko ikhethekileyo, ukhetho lwethu lweethegi zezothutho zezi:
1) Izinto ezikumphezulu ziphepha lobugcisa okanye iphepha elishushu, kwaye iglu yiglu yamanzi, enokwanelisa iimfuno kwaye ilawule iindleko.
2) Iimpahla ngokubanzi zinkulu kwaye zifuna ulwazi oluthe kratya ukuze ziprintwe kumphezulu, ngoko ke kukhethwa iithegi ezinkulu. (Ezifana: 4×2”, 4×6”, njl.njl.)
3)Iilebhile zokuthumela zeRFID kufuneka ube noluhlu olude lokufunda, ngoko ke kufuneka i-antenna enkulu enomlinganiselo omkhulu we-antenna. Indawo yokugcina nayo kufuneka ibe nkulu, ngoko sebenzisa iitships ezinememori ye-EPC phakathi kwe-96bits kunye ne-128bits, ezifana ne-NXP Ucode 8, Ucode9, Impinj Monza 730, M750. I-chip ye-Alien H9 nayo iyasetyenziswa, kodwa ngenxa yendawo yayo enkulu yokugcina indawo yomsebenzisi ye-688 bits kunye nexabiso eliphezulu, kukho ukhetho oluncinci.
Iimveliso ezinxulumene ne-XGSun
Iingenelo ze iithegi zeRFID zokulandelela izinto zokusebenza Ibonelelwe yi-XGSun: Iilebhile ezinkulu, imiqulu emincinci, ilandela iprotocol ye-ISO18000-6C, izinga lokufunda idatha yeelebhile linokufikelela kwi-40kbps ~ 640kbps. Ngokusekelwe kwitekhnoloji ye-RFID yokulwa nokungqubana, inani leelebhile ezinokufundwa ngaxeshanye linokufikelela kwi-1,000 ngokwethiyori. Inesantya sokufunda nokubhala esikhawulezayo, ukhuseleko lwedatha oluphezulu, kunye noluhlu lokufunda olude kwibhendi yefrikhwensi yokusebenza (860 MHz -960 MHz), enokufikelela kwiimitha ezili-10. Inomthamo omkhulu wokugcina idatha, ukufunda nokubhala okulula, ukuziqhelanisa kakuhle nokusingqongileyo, iindleko eziphantsi, ukusebenza ngexabiso eliphezulu, ubomi benkonzo ende kunye noluhlu olubanzi lwezicelo. Ikwaxhasa ukwenziwa ngokwezifiso.
