I. Nhanganyaya yekukurukurirana
vagadziri vechiteshi chekuchaja motaakati:"Kukurukurirana, yakashandisawo izwi rekuti kutaurirana, vamwe vanhu vanotenda kuti mavara akarerekera mhedzisiro, nepo nhau dzichifarira maitiro uye nzira, asi zvinoita sekunge pasina mutsauko wakawandisa mupfungwa yekuisa mumapoka haigone kuvhiringika. Kungave kunyorerwa kana kutaurirana, iko kushandiswa kwezviratidzo zvakasiyana-siyana, semagetsi, magineti, chiedza, nezvimwewo, kuendesa ruzivo rwunofanirwa kuratidzwa kune kwaunoenda. Semuenzaniso wakapfava, kana paine vadzidzi vaviri vanogara muBuilding 1 neBuilding 2, vanokurukura kuti kana vakaona hembe chena, vanosvetuka kirasi pamwechete nhasi. Pano zvinogona kurerutswa se, mune imwe mamiriro ezvinhu, chena shati = skip kirasi pamwe chete, inopindirana neprotocol yekukurukurirana, kuwedzera kune zviito zvakawanda zvinobatanidzwa: 1. kurembera shati chena 2. ona shati chena 3. chiedza chezuva zvakakwana kuti uone shati, zvichiteerana, inoenderana nedzidziso yekutaurirana ye encoding, decoding, chiteshi. Zvechokwadi, hupenyu chaihwo hwekutaurirana, huve hwakanyanya kuoma kupfuura muenzaniso wehembe chena, kudiwa kwekuvimbika, kugadzikana, hupfumi uye mamwe maonero ekufungisisa kusarudzwa kwechiteshi, pamwe chete nemari ye encoding uye decoding. midziyo uye zvichingodaro, semuenzaniso, tinogona kusarudza iyo 4G yeInternet yeZvinhu network network, asi mutengo wakakwira, unogona kusiya kumwe kugadzikana, kusarudza iyo GPRS Internet yezvinhu network network.
vagadziri vechiteshi chekuchaja motaakati: Pamusoro pezviito zvekutanga zveprotocol, encoding uye chiteshi chataurwa pamusoro, nyaya yakakosha mukutaurirana kweIOT kuita nhamba yekwakabva uye kwainoenda chero ruzivo, kureva kuti, kutaura zvakajeka WHO IS WHO, kuburikidza nenhamba. inogona kuona chero mudziyo uri munyika kwaunobva uye kwaunoenda, uye kuburikidza neicho nzira, ita kuti ruzivo rwuenderane neimwe nzira inofanirwa kufambiswa pakati pezviviri izvi. Izvi zvinonzi "addressing", iyo inotanga nekugovera kero, uye inoenderera mberi nekuita kuti chiratidzo chiwane kero yekuenda kuburikidza nemitemo chaiyo.
vagadziri vechiteshi chekuchaja motaakati: Iwo maviri akanyanya kukosha kero pfungwa muIoT kutaurirana iIP kero uye MAC kero. IP kero ndiyo kero inoshandiswa neInternet protocol, nepo MAC kero iri kero inoshandiswa neEthernet protocol. imwe nodi yeEthernet ine yakasarudzika pasi rose 48-bit kero, iyo inotungamirwa nesangano reIEEE, uye kero yeMAC inopiswa mune yega yega network kadhi nemugadziri makadhi. Mugadziri wetiweki kadhi anopisa kero yeMAC mukadhi rega rega, kero yeMAC yakasarudzika senhamba yechitupa. hukama hwemepu pakati pekero yeMAC nekero yeIP iri kuramba ichiwedzerwa uye ichivandudzwa nemuiti wega wega, inova "tafura yemepu yekero", uye kero yeIP inofananidzwa nenhamba yemusuwo. Saka mudziyo une imwe MAC1 ID kadhi, unogona nhasi mugonhi nhamba IP1 kuti ugare, unogona zvakare mangwana mune nhamba yemusuwo IP2 kuti ugare, iwowo MAC2 ID kadhi mudziyo unogona zvakare kuva muIP1 kuti ugare.
Inofananidzwa nekero dzeIP iURL (Uniform Resoure Locator) kero, zvichireva kuti Uniform Resource Locator, zvichireva kero yemafaira eInternet paWebhu, maURL anoshandisa nhamba nemabhii mune imwe kurongeka kuona kero, maURL anofanirwa kushandurwa kuita manhamba emasuo. (kureva, IP kero) nemaseva eDNS kutsvaga panoiswa faira paseva pawebhu.

vagadziri vechiteshi chekuchaja motaakati: 1. KUNOGONA kutaurirana pakati pemotokari neDC murwi zvichibva paGB/T 27930-2023
vagadziri vechiteshi chekuchaja motaakati:CAN ndiyo chidimbu cheController Area Network, inogadzirwa neBOSCH, kambani yekuGermany ine mukurumbira mukusimudzira nekugadzira zvigadzirwa zvemagetsi zvemotokari, uye pakupedzisira yakava chiyero chepasi rose (ISO11898), uye ndeimwe yenzvimbo inoshandiswa zvakanyanya. mabhazi munyika. KuNorth America neWestern Europe, CAN bhazi protocol rave bhazi rakajairwa remotokari macomputer ekudzora masisitimu uye yakamisikidzwa maindasitiri ekudzora maLAN, uye ine J1939 protocol yakagadzirirwa marori mahombe uye anorema muchina mota dzine CAN seyo iri pasi peprotocol.
vagadziri vechiteshi chekuchaja motaakati: Parizvino, China neJapan dzinoshandisa CAN bhazi kutaurirana muDC nekukurumidza kuchaja. Muchiyero chedu, kuyerera kwakawanda kweDC kuchaja kunotsanangurwa sezvizvi: kupedzwa kwekubatana kwemuviri - yakaderera-voltage yekubatsira simba-kumusoro - kuchaja handshake - parameter configuration - kuchaja - kutaurirana kusati kwapera - kupera kwekuchaja.
vagadziri vechiteshi chekuchaja motaakati:Mushure meiyo yakaderera-voltage yakabatsira simba-kumusoro, mota nemurwi zvinopinda muchikamu chekutaurirana kusvika kumagumo. Munguva yese yekutaurirana, mota uye murwi wekufambisa ruzivo pakati peumwe neumwe, isu tinoidaidza kuti "meseji", inotevera inobva pane yenyika standard meseji tsananguro pfupiso, iyo inotanga naC yeruzivo rwekuchaja, B inotanga nemotokari. VCU, BMS ruzivo, kuburikidza neidzi tsananguro, tinogona kuziva kuti kuchaja maitiro, mota yemagetsi uye murwi wekuchaja zvakangoita izvo zvinoda kuchinjana pakati pavo.
