I. Intshayelelo kunxibelelwano
abavelisi besikhululo sokutshaja iimotowathi:Unxibelelwano, lukwasebenzise igama elithi unxibelelwano, abanye abantu bakholelwa ukuba unobumba uneziphumo ezithambekele ecaleni, ngelixa iindaba zithanda inkqubo kunye nendlela, kodwa akubonakali kukho mahluko kakhulu kwingqikelelo yokwahlulahlulwa ayinakubhidaniswa. Nokuba yimbalelwano okanye unxibelelwano, kukusetyenziswa kwemiqondiso eyahlukeneyo, njengombane, umazibuthe, ukukhanya, njl. njl., ukuhambisa ulwazi oluza kuchazwa kwindawo ekuyiwa kuyo. Njengomzekelo olula, ukuba kukho abafundi ababini abahlala kwiSakhiwo soku-1 nakwiSakhiwo sesi-2, baxoxa ukuba xa bebona ihempe emhlophe, baya kutsiba iklasi kunye namhlanje. Apha kungenziwa lula njengoko, kwimeko ethile, ihempe emhlophe = tsiba iklasi kunye, ihambelana neprothokholi yonxibelelwano, ukongeza kwizenzo ezininzi ezibandakanyekayo: 1. ukuxhoma ihempe emhlophe 2. jonga ihempe emhlophe 3. ukukhanya kwemini ngokwaneleyo ukubona ihempe, ngokulandelelanayo, ehambelana nethiyori yonxibelelwano ye-encoding, i-decoding, itshaneli. Kakade ke, ubomi obuyinyani bonxibelelwano, ukuba bube nzima ngakumbi kunomzekelo wehempe emhlophe, imfuneko yokuthembeka, ukuzinza, uqoqosho kunye nezinye iimbono zokuqwalasela ukhetho lwejelo, kunye neendleko zokufaka iikhowudi kunye nokudibanisa. izixhobo kunye nokunye, umzekelo, sinokukhetha i-4G ye-intanethi ye-intanethi ye-intanethi ye-intanethi yonxibelelwano, kodwa ixabiso liphezulu, unokuyeka ezinye zozinzo, ukukhetha i-intanethi ye-intanethi ye-intanethi ye-intanethi ye-GPRS.
abavelisi besikhululo sokutshaja iimotouthe: Ukongeza kwizenzo ezisisiseko zeprotocol, i-encoding kunye nejelo elikhankanywe ngasentla, umba obalulekileyo kunxibelelwano lwe-IOT kukwenza inombolo yemvelaphi kunye nendawo yokuya kulo naluphi na ulwazi, oko kukuthi, ukuchaza ngokucacileyo WHO IS WHO, ngenani. inokuchonga nasiphi na isixhobo emhlabeni kwimvelaphi kunye nendawo ekuyiwa kuyo, kwaye ngendlela efanelekileyo, yenza ulwazi ngokwendlela ethile ekufuneka idluliselwe phakathi kwezi zibini. Oku kubizwa ngokuba "yidilesi", eqala ngendlela yokwabela idilesi, kwaye iqhubeke nendlela yokuvumela umqondiso ufumane idilesi yendawo ngemithetho ethile.
abavelisi besikhululo sokutshaja iimotouthe: Iikhonsepthi ezimbini ezibalulekileyo zedilesi kunxibelelwano lwe-IoT yidilesi ye-IP kunye nedilesi ye-MAC. Idilesi ye-IP yidilesi esetyenziswa yinkqubo ye-Intanethi, ngelixa idilesi ye-MAC iyidilesi esetyenziswa yi-Ethernet protocol. i-node nganye ye-Ethernet inedilesi ekhethekileyo ye-48-bit yehlabathi, elawulwa ngumbutho we-IEEE, kwaye idilesi ye-MAC itshiswa kwikhadi ngalinye lomnatha ngumenzi wekhadi. Umenzi wekhadi lothungelwano utshisa idilesi ye-MAC kwikhadi ngalinye, idilesi ye-MAC iyodwa njengenombolo yekhadi lesazisi. ubudlelwane bemephu phakathi kwedilesi ye-MAC kunye nedilesi ye-IP isoloko inyuswa kwaye ihlaziywa ngumninimzi ngamnye, othi "itafile yokubonisa idilesi", kwaye idilesi ye-IP ifaniswa nenombolo yomnyango. Ke isixhobo esinekhadi le-ID ye-MAC1, namhlanje kwinombolo yomnyango i-IP1 ukuhlala, nangomso kwinombolo yomnyango IP2 ukuhlala, kwa isixhobo se-ID ye-MAC2 efanayo sinokuba kwi-IP1 ukuhlala.
Ukuthelekiswa needilesi ze-IP ziidilesi ze-URL (i-Uniform Resoure Locator) idilesi, intsingiselo ye-Uniform Resource Locator, ibhekisa kwidilesi yeefayile ze-Intanethi kwiWebhu, ii-URL zisebenzisa amanani kunye noonobumba ngendlela ethile ukumisela idilesi, ii-URL kufuneka ziguqulelwe kwiinombolo zeminyango. (oko kukuthi, iidilesi ze-IP) ngabancedisi be-DNS ukufumana apho ifayile ibekwe khona kumncedisi kwiwebhu.
II. Unxibelelwano lweNgqungquthela yeThuthi
abavelisi besikhululo sokutshaja iimotowathi: 1. Unxibelelwano lwe-CAN phakathi kwemoto kunye ne-DC imfumba esekelwe kwi-GB / T 27930-2023
abavelisi besikhululo sokutshaja iimotowathi:CAN sisishunqulelo se-Controller Area Network, ephuhliswa yi-BOSCH, inkampani yaseJamani edume ngophuhliso kunye nokuveliswa kweemveliso ze-elektroniki zemoto, kwaye ekugqibeleni yaba ngumgangatho wamazwe ngamazwe (ISO11898), kwaye yenye yezona ndawo zisetyenziswa kakhulu kwintsimi. iibhasi ehlabathini. ENyakatho Melika naseNtshona Yurophu, i-CAN ibhasi ye-protocol iye yaba yibhasi eqhelekileyo kwiinkqubo zokulawula iikhompyutheni zeemoto kunye nee-LAN zokulawula i-industrial, kwaye ine-protocol ye-J1939 eyenzelwe iilori ezinkulu kunye neenqwelo ezinkulu zoomatshini kunye ne-CAN njengeprotocol ephantsi.
abavelisi besikhululo sokutshaja iimotoYathi:Okwangoku, iTshayina neJapan zisebenzisa i-CAN unxibelelwano lwebhasi kwi-DC ukutshaja ngokukhawuleza. Ngokomgangatho wethu, ukuhamba ngokubanzi kokutshaja kwe-DC kuchazwa ngolu hlobo lulandelayo: ukugqitywa koxhumo lomzimba - i-low-voltage i-auxiliary power-up - ukutshaja i-handshake - ukucwangciswa kweparameter - ukutshaja - unxibelelwano ngaphambi kokuphela - ukuphela kokutshaja.
abavelisi besikhululo sokutshaja iimotowathi:Emva kwe-low-voltage incedise amandla-up, isithuthi kunye nemfumba ingena kwisigaba sonxibelelwano kude kube sekupheleni. Kuyo yonke inkqubo yonxibelelwano, isithuthi kunye nemfumba yokudlulisa ulwazi phakathi komnye nomnye, siyibiza ngokuthi "umyalezo", oku kulandelayo kusekelwe kwisishwankathelo senkcazo yenkcazo yomyalezo wesizwe, oqala nge-C yolwazi lwemfumba yokutshaja, B iqala ngesithuthi I-VCU, ulwazi lwe-BMS, ngezi nkcazo, siyakwazi ukuba inkqubo yokutshaja, isithuthi sombane kunye nemfumba yokutshaja ngokumalunga noko kufuneka kutshintshiswe phakathi kwabo.
