CAN (CantrollerAreaNetwork) system bhazi, kureva kuti, iyo control panel yenharaunda nharaunda network system bhazi, yakashandiswa zvakanyanya mumaindasitiri ekudzora masisitimu, zvigadzirwa zvemagetsi uye maindasitiri ekunzwa. Iyo CAN bhazi protocol ine 2 yenyika zviyero, zvinoti ISO11898 uye ISO011519. Pakati pavo, ISO11898 ndeyekumhanya-mhanya kwekutaura, iyo yekutaurirana kumhanya ndeye 125kbps ~ 1Mbps; iyo yakakura yekutaurirana kureba ndeye 40m/1Mbps, inova yeyakavharwa-loop control system bhazi.
ISO011519 ishongedzo yekumhanya yakaderera ine kukurumidza kwekutaurirana kwe10kbps kusvika 125kbps. Iyo yakakura yekutaurirana chinhambwe ndeye 1Km/40kbps, inova yeyakavhurika-loop transmission multihead weigher function system bhazi. Huwandu hwepamusoro hwemapoinzi ekubatanidza paCAN bhazi i110 nekuda kwenjodzi yeiyo system bus contact resistance uye resistor kune system bus waveform.
Kana iyo yekugamuchira uye yekutumira yekupedzisira serial port baud chiyero uye bit main paramita akashongedzerwa zvakanaka, iyo dhatabhesi yekubatanidza yekugamuchira uye kutumira mapoinzi inogona kupedzwa. Inogona kufambisa data multihead weigher nenzira dzinoverengeka senge point-to-point, point-to-multipoint uye zvirongwa zvekutepfenyura zvepasi rose. Kana paine nzvimbo yekubatanidza paCAN bhazi kuendesa data, inotumirwa kune ese mapoinzi ekubatanidza muInternet mune meseji fomati.
Kune imwe neimwe yekubatanidza nzvimbo, iyo data data inogamuchirwa zvisinei kuti inotumirwa kune yega kana kwete. Iyo 11-bit identifier pakutanga kweboka rega rega remeseji mafomati identifier, iyo inotsanangura kukosha kweiyo meseji fomati. Iyo meseji fomati identifier yakasarudzika mune imwecheteyo system software, zvikasadaro kutaurirana kuchave kwakashata; iwo chaiwo maitiro ndeaya anotevera: kana chiteshi ichida kuendesa data kune zvimwe zviteshi, iyo CPU yechiteshi ichi inoendesa iyo data data uye yayo identifier. Iyo CAN yakasanganiswa ic yewebhusaiti ino iri mumamiriro ekugadzirira pamberi; painogashira kutumirwa kubva kune system bhazi, inova iyo mamiriro eiyo push meseji fomati.
Iyo CAN yakasanganiswa ic inotumira iyo data chiratidzo chemultihead weigher ruzivo kune imwe meseji fomati zvinoenderana neprotocol uye inotumira kune system bhazi. Panguva ino, zvimwe zviteshi mubhazi rehurongwa zviri munzvimbo yekugamuchira, uye chiteshi chimwe nechimwe chiri munzvimbo yekugamuchira chinopindura kune yakagamuchirwa meseji. Iyo fomati yemavara inoedzwa, uye kana yakatumirwa kune yega, iyo data data kuongororwa kunoitwa. Ko kana paine akawanda mamwe data anofambiswa kana system bhazi yakasununguka? Kutanga, iyo fomati yeimwe push meseji inogamuchirwa uye inosiyaniswa. Ani nani ane chepamusoro-soro achagara mubhazi rehurongwa, uye vamwe vachasiiwa. Semuyenzaniso: chiteshi 1, chiteshi 2, chiteshi 3 zvakare sunda iyo meseji fomati kune system bhazi: 011111, 0100110, 0100111; iyo system bhazi inosiyanisa iyo meseji fomati, madhijiti maviri ekutanga akafanana, uye wozosiyanisa nhamba yechitatu, chiteshi 1 Chechitatu bhiti 1, iyo meseji fomati ichasiiwa, chete chiteshi 2 uye chiteshi 3 chasara, mukati izvo zvitanhatu zvekutanga zvezviteshi zviviri izvi zvakafanana, uye yechinomwe yechiteshi 3 i1, iyo ichasiiwa zvakare, uye pakupedzisira chete Iyo meseji fomati yechiteshi 2 inochengetwa, zvimwe zviteshi zviri munzvimbo yekugamuchira, uye hazvisi nyore kusunda iyo meseji fomati bhazi rehurongwa risati rasununguka zvakare.
Iyi ndiyo nzira yekukurudzira ye system bus multihead weigher yeCAN kutaurirana;.
