I. Nhanganyaya yekutaurirana
vagadziri vezviteshi zvekuchaja motaAkati：Kutaurirana, zvakare izwi rekuti kutaurirana, vamwe vanhu vanotenda kuti tsamba yacho ine mhedzisiro yakarerekera, nepo nhau dzichifarira maitiro nenzira, asi hazviratidzike kunge paine musiyano wakanyanya mupfungwa yekupatsanurana hakugone kukanganiswa. Ingave iri kutaurirana kana kutaurirana, iko kushandiswa kwezviratidzo zvakasiyana-siyana, zvakaita semagetsi, magineti, chiedza, nezvimwewo, kutumira ruzivo rwunofanirwa kuratidzwa kunzvimbo yaunoda kuenda. Semuenzaniso wakapusa, kana paine vadzidzi vaviri vanogara muKuvaka 1 neKuvaka 2, vanokurukura kuti kana vakaona hembe chena, vachasvetuka kirasi pamwe chete nhasi. Pano zvinogona kurerutswa se, mune imwe mamiriro ezvinhu, hembe chena = skip kirasi pamwe chete, zvinoenderana neprotocol yekutaurirana, kuwedzera kune zviito zvakati wandei zvinosanganisirwa: 1. kuturika hembe chena 2. ona hembe chena 3. chiedza chemasikati chakakwana kuti uone hembe, zvichiteerana, zvinoenderana nedzidziso yekutaurirana yekunyora, kutsanangura, chiteshi. Ehe, hupenyu chaihwo hwekutaurirana, kuti huve hwakaoma kupfuura muenzaniso wehembe chena, kudiwa kwekuvimbika, kugadzikana, hupfumi uye mamwe maonero ekufunga nezvesarudzo yechiteshi, pamwe nemutengo wekushandisa encoding ne decoding michina nezvimwewo, semuenzaniso, tinogona kusarudza 4G yeInternet of Things communication network, asi mutengo wacho wakakwira, unogona kusiya zvimwe zvekugara zvakanaka, kuti usarudze GPRS Internet of Things communication network.
vagadziri vezviteshi zvekuchaja motaakati: Pamusoro pezviito zvekutanga zveprotocol, encoding uye channel zvataurwa pamusoro apa, nyaya yakakosha mukutaurirana kweIOT ndeyekuita nhamba yekwakabva uye kwainoenda chero ruzivo, kureva kuti, kuratidza zvakajeka kuti NDIANI NDIANI, kuburikidza nenhamba inogona kuziva chero mudziyo uri munyika pakwakabva uye kwainoenda, uye kuburikidza nenzira yakakodzera, kugadzira ruzivo maererano nenzira yakati kuti iendeswe pakati pezviviri. Izvi zvinonzi "addressing", iyo inotanga nemaitiro ekugovera kero, uye inoenderera mberi nemaitiro ekurega chiratidzo chiwane kero yekwainoenda kuburikidza nemitemo chaiyo.
vagadziri vezviteshi zvekuchaja motaakati：Dzidziso mbiri dzakakosha dzekero mukutaurirana kweIoT ikero yeIP nekero yeMAC. Kero yeIP ndiyo kero inoshandiswa neprotocol yeInternet, nepo kero yeMAC iri kero inoshandiswa neprotocol yeEthernet. Node yega yega yeEthernet ine kero ye48-bit yakasiyana pasi rose, iyo inotungamirwa nesangano reIEEE, uye kero yeMAC inopiswa mukadhi rega rega renetwork nemugadziri wekadhi. Mugadziri wekadhi renetwork anopisa kero yeMAC mukadhi rega rega, kero yeMAC yakasiyana senhamba yekadhi rekuziva. Hukama hwemapping pakati pekero yeMAC nekero yeIP huri kuramba huchiwedzerwa uye huchivandudzwa nehost yega yega, iyo inova "tafura yemepu yekero", uye kero yeIP inofananidzwa nenhamba yemusuwo. Saka mudziyo une kadhi reID reMAC1, nhasi unogona kugara munhamba yeIP1 yemusuwo, unogona zvakare mangwana kugara munhamba yeIP2 yemusuwo, mudziyo wekadhi reID reMAC2 rimwechete unogona zvakare kuva muIP1 kuti ugare.
Makero eIP akafanana neakero dzeURL (Uniform Resoure Locator), zvichireva kuti Uniform Resource Locator, zvichireva kero yemafaira eInternet paWeb, maURL anoshandisa manhamba nemabhii nenzira yakati kuti aone kero, maURL anofanira kushandurwa kuita manhamba emusuwo (kureva, maIP address) nemaDNS servers kuti awane nzvimbo inoiswa faira paserver paWeb.
II. Kutaurirana neMotokari
vagadziri vezviteshi zvekuchaja motaakati: 1. Kutaurirana kweCAN pakati pemotokari neDC pile kwakavakirwa paGB/T 27930-2023
vagadziri vezviteshi zvekuchaja motaakati：CAN ipfupiso yeController Area Network, iyo yakagadzirwa neBOSCH, kambani yekuGermany inozivikanwa nekugadzira nekugadzira zvigadzirwa zvemagetsi zvemotokari, uye yakazopedzisira yava mwero wepasi rose (ISO11898), uye ndeimwe yemabhazi anoshandiswa zvakanyanya pasi rose. MuNorth America neWestern Europe, CAN bus protocol yave bhazi rakajairika remacomputer control systems emota uye embedded industrial control LANs, uye ine J1939 protocol yakagadzirirwa marori makuru nemota dzemichina inorema ine CAN seprotocol iri pasi.
vagadziri vezviteshi zvekuchaja motaakati：Parizvino, China neJapan vanoshandisa kutaurirana kwebhazi reCAN mukuchaja nekukurumidza kweDC. Muchiyero chedu, kufamba kweDC kuchaja kunotsanangurwa seinotevera: kupedzisa kubatana kwemuviri - simba rekubatsira remagetsi mashoma - kukwazisana nemaoko - kugadzika kwema parameter - kuchaja - kutaurirana usati wapedza kuchaja.
vagadziri vezviteshi zvekuchaja motaakati: Mushure mekubatidzwa kwesimba nemagetsi mashoma, mota nepaburi zvinopinda muchikamu chekutaurirana kusvika kumagumo. Mukati memaitiro ese ekutaurirana, mota nepaburi zvinotamisa ruzivo pakati peumwe neumwe, tinozvidaidza kuti "meseji", zvinotevera zvakavakirwa pachidimbu chetsanangudzo yemeseji yenyika, chinotanga naC yeruzivo rwepaburi rekuchaja, B inotanga neruzivo rwemotokari VCU, ruzivo rweBMS, kuburikidza netsanangudzo idzi, tinogona kuziva kuti maitiro ekuchaja, mota yemagetsi nepaburi rekuchaja zvinenge zvinoda kuchinjaniswa pakati pavo.
