Nheyo huru yekutaurirana kweCAN patafura yekuyera misoro yakawanda haina kudzika

Munyori: Smartweigh– Huremu hwemisoro yakawanda

Bhazi reCAN (CantrollerAreaNetwork), kureva kuti, bhazi rehurongwa hwenetwork yenzvimbo yemuno, rave richishandiswa zvakanyanya mumaindasitiri ekudzora, zvigadzirwa zvemagetsi uye maindasitiri e sensor. Nzira yebhazi reCAN ine zviyero zviviri zvenyika, zvinoti ISO11898 neISO011519. Pakati pazvo, ISO11898 imhando yekutaurirana nekukurumidza, kumhanya kwekutaurirana i125kbps ~ 1Mbps; daro guru rekutaurirana i40m/1Mbps, iro riri rebhazi rehurongwa hwekudzora rakavharika.

ISO011519 imhando yekutaurirana inomhanyisa zvishoma ine kumhanya kwekutaurirana kwe10kbps kusvika 125kbps. Daro guru rekutaurirana i1Km/40kbps, inova yebhazi remagetsi rinoshandisa ma "open-loop transmission multihead weigher". Huwandu hwenzvimbo dzekubatanidza pabhazi reCAN i110 nekuda kwenjodzi yekudzivirira bhazi remagetsi uye resistor kune waveform yebhazi remagetsi.

Kana chiyero chekutumira nekutumira data remagetsi uye bit main parameters zvakashongedzerwa zvakanaka, kuenderana kwedatabase kwemapoinzi ekugamuchira nekutumira kunogona kupedzwa. Inogona kutumira data remaheavyweighter nenzira dzakasiyana siyana dzakadai se point-to-point, point-to-multipoint uye mapurogiramu epasi rose ekuparadzira data. Kana paine nzvimbo yekubatanidza pabhazi reCAN yekutumira data, inotumirwa kunzvimbo dzese dzekubatanidza paInternet muchimiro chemeseji.

Panzvimbo yega yega yekubatanidza, ruzivo rwedata rwunogamuchirwa zvisinei nekuti rwunotumirwa kwarwo here kana kuti kwete. Chiratidzo che11-bit pakutanga kweboka rega rega remafomati emeseji chiratidzo, icho chinotsanangura kukosha kwefomati yemeseji. Chiratidzo chefomati yemeseji chakasiyana mune imwe software yesystem, zvikasadaro kutaurirana kuchave kusina kunaka; maitiro chaiwo ndeekuti: kana chiteshi chichida kutumira data kune dzimwe nzvimbo, CPU yechiteshi ichi inotumira ruzivo rwedata uye chiratidzo chayo. Iyo CAN yakabatanidzwa ic yewebhusaiti iyi iri mumamiriro ekugadzirira pachine nguva; painogamuchira dispatch kubva ku system bus, inova mamiriro efomati yemeseji ye push.

Iyo CAN integrated ic inotumira ruzivo rwe data signal multihead weigher kune imwe meseji format zvichienderana neprotocol uye inoitumira ku system bus. Panguva ino, zvimwe zviteshi zviri mu system bus zviri mu receiving state, uye station yega yega iri mu receiving state inopindura meseji yakagamuchirwa. Rudzi rwemashoko rwunoedzwa, uye kana rwukatumirwa kwarwo, ongororo yeruzivo rwedata inoitwa. Ko kana paine mamwe data akawanda anofanira kutumirwa kana system bus iri yemahara? Kutanga, fomati yeimwe push message inogamuchirwa uye inosiyaniswa. Ani nani ane push yepamusoro achagara mu system bus, uye mamwe achasiyiwa. Semuenzaniso: station 1, station 2, station 3 inosundirawo meseji format ku system bus: 011111, 0100110, 0100111; Bhazi rehurongwa richasiyanisa fomati yemeseji, manhamba maviri ekutanga akafanana, uye wobva wasiyanisa nhamba yechitatu, chiteshi 1. Chikamu chechitatu i1, fomati yemeseji ichasiyiwa, chiteshi chechipiri nechiteshi chechitatu chete ndizvo zvasara, umo mabhiti matanhatu ekutanga ezviteshi zviviri izvi akafanana, uye chikamu chechinomwe chechiteshi 3 i1, icho chichasiyiwawo, uye pakupedzisira chete. Fomu yemeseji yechiteshi 2 inochengetwa, zvimwe zviteshi zviri muchimiro chekugamuchira, uye hazvisi nyore kusundidzira fomati yemeseji bhasi rehurongwa risati rasununguka zvakare.

Iyi ndiyo nzira yekukurudzira yesystem bus multihead weigher yekutaurirana kweCAN;.
