I. Intshayelelo kunxibelelwano
abavelisi bezikhululo zokutshaja iimotowathi: Unxibelelwano, lukwasebenzisa igama elithi unxibelelwano, abanye abantu bakholelwa ukuba ileta ineziphumo ezingathathi cala, ngelixa iindaba zikhetha inkqubo nendlela, kodwa akubonakali kukho umahluko omkhulu kwingcamango yokwahlulahlula ayinakuphazanyiswa. Nokuba yimbalelwano okanye unxibelelwano, kukusetyenziswa kwemiqondiso eyahlukeneyo, njengombane, imagnetism, ukukhanya, njl.njl., ukuhambisa ulwazi oluza kubonakaliswa kwindawo oya kuyo. Njengomzekelo olula, ukuba kukho abafundi ababini abahlala kwiSakhiwo 1 nakwiSakhiwo 2, baxoxa ngokuba ukuba babona ihempe emhlophe, baya kudlula iklasi kunye namhlanje. Apha kungenziwa lula njengoko, kwimeko ethile, ihempe emhlophe = dlula iklasi kunye, ihambelana neprotocol yonxibelelwano, ukongeza kwizenzo ezininzi ezibandakanyekayo: 1. ukuxhoma ihempe emhlophe 2. jonga ihempe emhlophe 3. ukukhanya kwemini ngokwaneleyo ukubona ihempe, ngokulandelelana, ehambelana nethiyori yonxibelelwano yokubhala ikhowudi, ukucacisa, itshaneli. Kakade ke, ubomi bokwenyani bonxibelelwano, ukuba bube nzima kakhulu kunomzekelo wehempe emhlophe, imfuneko yokuthembeka, uzinzo, uqoqosho kunye nezinye iimbono zokuqwalasela ukhetho lwetshaneli, kunye neendleko zokufaka ikhowudi kunye nezixhobo zokubhala ikhowudi njalo njalo, umzekelo, singakhetha i-4G yenethiwekhi yonxibelelwano ye-Intanethi yezinto, kodwa ixabiso liphezulu, ungayeka ezinye zozinzo, ukuze ukhethe inethiwekhi yonxibelelwano ye-GPRS Internet yezinto.
abavelisi bezikhululo zokutshaja iimotowathi: Ukongeza kwizenzo ezisisiseko zeprotocol, i-encoding kunye ne-channel ekhankanyiweyo apha ngasentla, umba obalulekileyo kunxibelelwano lwe-IOT kukwenza inombolo yemvelaphi kunye nendawo yolwazi, oko kukuthi, ukuchaza ngokucacileyo ukuba NGUBANI NGUBANI, ngenombolo unokuchonga nasiphi na isixhobo ehlabathini kwindawo yolwazi kunye nendawo yolwazi, kwaye ngendlela efanelekileyo, wenze ulwazi ngokwendlela ethile eza kudluliselwa phakathi kwezi zimbini. Oku kubizwa ngokuba yi-"addressing", eqala ngendlela yokwabela idilesi, kwaye iqhubeka nendlela yokuvumela isignali ukuba ifumane idilesi yendawo yolwazi ngemithetho ethile.
abavelisi bezikhululo zokutshaja iimotowathi：Iingcamango ezimbini ezibalulekileyo zedilesi kunxibelelwano lwe-IoT yidilesi ye-IP kunye nedilesi ye-MAC. Idilesi ye-IP yidilesi esetyenziswa yiprotocol ye-Intanethi, ngelixa idilesi ye-MAC yidilesi esetyenziswa yiprotocol ye-Ethernet. I-node nganye ye-Ethernet inedilesi ye-48-bit eyahlukileyo kwihlabathi liphela, elawulwa yintlangano ye-IEEE, kwaye idilesi ye-MAC itshiswa kwikhadi ngalinye lenethiwekhi ngumenzi wekhadi. Umenzi wekhadi lenethiwekhi utshisa idilesi ye-MAC kwikhadi ngalinye, idilesi ye-MAC yahlukile njengenombolo yekhadi lesazisi. Ubudlelwane bemephu phakathi kwedilesi ye-MAC kunye nedilesi ye-IP buhlala bunyuswa kwaye buhlaziywa ngumsingathi ngamnye, nto leyo eba "yitafile yemephu yedilesi", kwaye idilesi ye-IP ifaniswa nenombolo yomnyango. Ngoko ke isixhobo esinekhadi le-ID le-MAC1 elithile, namhlanje sinokuhlala kwinombolo yomnyango ye-IP1, sinokuhlala ngomso kwinombolo yomnyango ye-IP2, isixhobo sekhadi le-ID le-MAC2 elifanayo sinokuba kwi-IP1 ukuze sihlale.
Xa kuthelekiswa needilesi ze-IP kukho iidilesi ze-URL (Uniform Resoure Locator), oko kuthetha i-Uniform Resource Locator, ebhekisa kwidilesi yeefayile ze-Intanethi kwiWebhu, ii-URL zisebenzisa amanani kunye noonobumba ngokulandelelana okuthile ukumisela idilesi, ii-URL kufuneka ziguqulwe zibe ziinombolo zomnyango (oko kukuthi, iidilesi ze-IP) ziiseva ze-DNS ukuze kufunyanwe apho ifayile ibekwe khona kwiseva kwiwebhu.
II. Unxibelelwano ngeenqwaba zezithuthi
abavelisi bezikhululo zokutshaja iimotowathi: 1. Unxibelelwano lwe-CAN phakathi kwesithuthi kunye ne-DC pile olusekelwe kwi-GB/T 27930-2023
abavelisi bezikhululo zokutshaja iimotosathi：I-CAN sisifinyezo seController Area Network, esiphuhliswe yiBOSCH, inkampani yaseJamani edume ngophuhliso kunye nokuveliswa kweemveliso ze-elektroniki zeemoto, kwaye ekugqibeleni yaba ngumgangatho wamazwe ngamazwe (ISO11898), kwaye yenye yeebhasi zasentsimini ezisetyenziswa kakhulu kwihlabathi liphela. EMntla Melika naseNtshona Yurophu, iprotocol yebhasi ye-CAN iye yaba yibhasi eqhelekileyo yeenkqubo zolawulo lweekhompyutha zeemoto kunye neeLAN zolawulo lwemizi-mveliso ezifakiweyo, kwaye ineprotocol ye-J1939 eyenzelwe iilori ezinkulu kunye nezithuthi zoomatshini abanzima kunye ne-CAN njengeprotocol esisiseko.
abavelisi bezikhululo zokutshaja iimotowathi: Okwangoku, iTshayina neJapan zisebenzisa unxibelelwano lwebhasi yeCAN ekutshajeni ngokukhawuleza kweDC. Kwimigangatho yethu, ukuhamba ngokubanzi kokutshaja kweDC kuchazwa ngolu hlobo lulandelayo: ukugqitywa koqhagamshelo olubonakalayo - umbane oncedisayo we-voltage ephantsi - ukutshaja ngesandla - uqwalaselo lweparameter - ukutshaja - unxibelelwano ngaphambi kokuphela kokutshaja.
abavelisi bezikhululo zokutshaja iimotowathi: Emva kokuba umbane uncediswe yi-low-voltage, imoto kunye nenqwaba zingena kwisigaba sonxibelelwano kude kube sekupheleni. Kuyo yonke inkqubo yonxibelelwano, isithuthi kunye nolwazi lokudlulisela inqwaba phakathi komnye nomnye, silubiza ngokuba "ngumyalezo", oku kulandelayo kusekelwe kwisishwankathelo senkcazo yemiyalezo esemgangathweni kazwelonke, eqala ngo-C kulwazi lwenqwaba yokutshaja, u-B uqala ngesithuthi i-VCU, ulwazi lwe-BMS, ngezi nkcazo, singazi ukuba inkqubo yokutshaja, isithuthi sombane kunye nenqwaba yokutshaja malunga noko kufuneka kutshintshiselwane phakathi kwazo.
