Emishinini yokwakha, imishini yezolimo yesimanje, ama-coaches abagibeli kanye neminye imikhakha, ibhasi le-CAN lisebenza njengomgogodla wokuxhumana oyinhloko wesistimu yokulawula kagesi yezimoto ephelele, elinomthwalo wokudlulisa idatha kanye nokusebenzisana komyalo phakathi kwenjini, i-gearbox kanye nezinzwa zangaphandle. Njengesikhungo esiyinhloko sokusebenzisana kwabantu nomshini kanye nokuqoqwa kwedatha ekhabini, inani kanye nokusebenza kweziteshi ze-CAN kumathebhulethi aqinile afakwe emotweni kunquma ngqo ubuqotho bokuqoqwa kwedatha yemoto kanye nokuqina kokuxhumana. Lesi sihloko sizochaza umehluko obalulekile phakathi kwe-CAN eyodwa kanye ne-CAN ezimbili, kanye nezindawo zazo eziyinhloko zokusetshenziswa, ukusiza amakhasimende ukugwema izingibe ezivamile zokuthengwa njenge-CAN eyenziwe ngesofthiwe kanye neziteshi ezandisiwe zesango ezithengiswa ngamanga njengehadiwe ye-CAN eminingi.
Iziteshi Zehadiwe ze-CAN Ezizimele Zomdabu vs. I-CAN Enwetshiwe Yesango / Isofthiwe Elingiswayo
Umgomo owodwa wokwahlulela ikhono le-CAN lethebhulethi eqinile ukuthi ngabe i-SoC yebhodi elikhulu ihlanganisa yini izinto ezisetshenziswayo zokulawula i-CAN. Iziteshi ezinwetshiwe nge-CAN eyenziwe ngesofthiwe noma amasango e-CAN angaphandle e-USB/Ethernet azikwazi ukulingana nokusebenza kwehadiwe, futhi izikhala eziyisisekelo zehadiwe phakathi kwezixazululo ezimbili azikwazi ukukhokhelwa ngokulungiswa kwesofthiwe.
Ukucushwa Okujwayelekile Kwehadiwe Yomdabu I-CAN
Isiteshi ngasinye sihlonyiswe ngezinsizakusebenza zehadiwe ezikhethekile: isilawuli se-CAN esizimele, i-transceiver ye-CAN esheshayo esizimele, i-resistor yokufanisa i-terminal ezimele, ukunikezwa kwamandla okuhlukanisiwe kanye nesekethe yokuhlukanisa yedijithali, kanye ne-TVS yokuvikela ukukhuphuka okuzimele. Ukunikezwa kwamandla, isekethe yomhlabathi kanye nesignali yazo zonke iziteshi kuhlukanisiwe ngokuphelele ngogesi. Izifunda ezimfushane, ukukhishwa kwe-electrostatic noma ukuphazamiseka kokukhuphuka kwesiteshi esisodwa ngeke kusakazekele kwesinye isiteshi, kususa ingozi yokusabalala kwamaphutha kuzo zonke izingxenye zenethiwekhi.
Izingqinamba Eziyinhloko ze-Gateway-Expanded / Software-Simulated CAN
Amasango ayimishini yokudlulisa iphrothokholi. Yonke imiyalezo ye-CAN yabelana ngezinsizakusebenza ezifanayo zokucubungula i-CPU kanye nesizinda samandla esisodwa ngaphandle kokuhlukaniswa kwehadiwe. Ivolumu yedatha ebekwe ngaphezulu evela ezigabeni eziningi zamabhasi yandisa kakhulu umthwalo we-CPU futhi yethula ukubambezeleka kokudlulisa ezingeni le-millisecond. Ukwehluleka kwesango kungaphazamisa zonke izingxenye zamabhasi ezixhunyiwe ngasikhathi sinye, futhi ezimweni ezimbi kakhulu kubangele ukuphazamiseka kokuxhumana kwe-ECU yemoto ephelele. Izixazululo ezinjalo azihlangabezani nezidingo zokuphepha zezimoto zokwakha, futhi zifanelekela kuphela ukulungisa iphutha lesikhashana kunokuqapha okuqhubekayo kwemikhumbi amahora angama-24 ngosuku, izinsuku eziyi-7 ngesonto.
I-CAN Eyodwa (Imodeli Elula Yezinga Lokungena)
Ifakwe isethi eyodwa kuphela yesilawuli se-CAN kanye ne-transceiver yesiteshi esisodwa, esekela ukuxhumana nengxenye eyodwa yebhasi. Ezimotweni ezinezakhiwo eziningi zamabhasi, ama-wiring harnesses kumele akhishwe ngesandla futhi axhunywe kabusha ukuze kushintshwe ukutholwa kwedatha, okwenza ukufundwa okuhambisanayo kwezimo zokusebenza ezivela ezinhlelweni ezimbili ezizimele kungenzeki. Uma inani elikhulu lama-node kanye nemithwalo yemiyalezo esindayo isebhasini, izinga lomthwalo webhasi lidlula kalula umkhawulo wengozi ongu-70%, okuholela ekuminyaneni kwemiyalezo emugqeni, ukulahleka kwephakethe ngezikhathi ezithile kanye nokuphakama okubukhali kokulibaziseka kokuxhumana. Ukuqapha isimo semoto ngesikhathi sangempela kanye nemisebenzi yokuxilonga ejulile ye-UDS ayikwazi ukusebenza ngesikhathi esisodwa; ukukhanya kwe-ECU kanye nokuxazulula izinkinga kudinga ukunqanyulwa kwesixhumanisi sokuqapha imoto nokuphazamisa ukulayishwa kwedatha yezimoto.I-Single CAN isebenza kuphela ezimweni eziyisisekelo eziqukethe ukwakheka kwebhasi lemoto eyodwa, izinhlelo zokulawula ze-elekthronikhi ezilula kanye nezidingo zokuxilonga amaphutha okujula.
I-CAN Ekabili (Imodeli Ejwayelekile Ejwayelekile)
Ibhodi elikhulu lihlanganisa amayunithi amabili ehadiwe e-CAN azimele ngokuphelele, ahlukaniswe ngogesi. Iziteshi ezimbili azincintisani ngezinsizakusebenza zehadiwe, zingahlelwa ngokuzimela ngamanani ahlukene e-baud, futhi zisekela ukuxhumana okushesha okuhambisanayo okufika ku-1 Mbps. Ukuqoqwa kwedatha yamabhasi amabili ahambisanayo, ukuqapha kanye nokuxilonga kuyasekelwa, okuhlanganisa ngaphezu kuka-90% wezimo zokusebenza ezivamile zezimoto ezisindayo, okwenza kube ukucushwa okujwayelekile kwezimboni zokwakha, zempahla kanye nemishini yezolimo.
1. Ukuqoqwa Kwedatha Yebhasi Elimbili Elihambisanayo Ukuze Kutholakale Imininingwane Egcwele Yokusebenza:
Isiteshi 1 sixhuma ebhasini lamandla i-J1939 (injini, i-transmission, uhlelo lokubhuleka), kuyilapho isiteshi 2 sixhuma ebhasini le-hydraulic noma ebhasini lokulawula umzimba. Abaqhubi bangabuka isimo sokusebenza kuthebhulethi, futhi ipulatifomu yangemuva ihlanganisa idatha yokusebenza ngesikhathi sangempela ngaphandle kokushintsha izintambo noma ukuqoqwa kwedatha yokwabelana ngesikhathi.
2. Ukuqapha Nokuxilonga Okuhambisanayo kwe-KungconoUkulungiswa:
Isiteshi 1 sigcina ukulayishwa kwangempela kwesimo semoto, ukusetshenziswa kukaphethiloli kanye nama-alamu amaphutha amahora angama-24 ngosuku, izinsuku eziyi-7 ngesonto ukuze kuqashwe njalo izimoto. Isiteshi 2 senza ukuhlolwa kwamaphutha ajulile e-UDS kanye nohlelo lwe-ECU olukhanya ngaphandle kokuphazamisa ukuqapha, okuthuthukisa kakhulu ukusebenza kahle kokugcinwa kwezimoto.
3. Ukuhlukaniswa Phakathi Kwebhasi Lemoto Yokuqala Nezingxenyana Zomgwaqo Ukuze Kuqedwe Ukuphazamiseka:
Iziteshi ezinikezelwe zihlukanisa uhlelo lokulawula oluyingqikithi lwemoto nezinto zangaphandle. Ukungasebenzi kahle noma ukuphazamiseka kokunyakaza okuvela ezintweni zangaphandle kuhlala kuvinjelwe esiteshini esisodwa futhi akunakungena ebhasini lamandla lokuqala, okuqinisekisa ukusebenza okuzinzile nokuphephile kohlelo lokulawula oluphelele lwemoto.
Umhlahlandlela Wokukhetha Okuqondiwe: Ukucushwa Okuhle Kakhulu Kwezimo Ezihlukene Zokusebenza
1. Khetha i-CAN eyodwa ye:
Izimoto zokulethwa kwezinto ezilula, ama-forklift amancane asefektri kanye nezinqola zokudlulisa; izimo zokusebenzisa ezidinga indawo eyisisekelo kuphela, isivinini semoto kanye nokufundwa kokusetshenziswa kukaphethiloli, ngaphandle kokuxilongwa kwephutha noma izinto ezisetshenziswayo ze-hydraulic/ezolimo.
2.Khetha i-Dual CAN ye:
Imishini yokumba encane nephakathi nendawo, ama-loader nama-roller omgwaqo; amaloli asindayo ajwayelekile, amaloli e-muck kanye nezinqola zabagibeli; ama-tractor amancane naphakathi nendawo kanye nemishini yokuvuna; ukuqapha njalo izimoto kanye namaphrojekthi okuxilonga ukulungiswa kwazo.
Isiphetho
Ukucushwa kwesiteshi sebhasi le-CAN kuyinkomba eyinhloko enquma ukuguquguquka kwesimo sokusebenza kwamaphilisi aqinile afakwe emotweni, kunokuba kube yipharamitha yokusiza ongayikhetha. Ukukhetha okunengqondo kokucushwa kwesiteshi se-CAN ngokusekelwe ezimweni zokusebenza kugwema ngempumelelo izinkinga ezifaka ukuhambisana okwanele kwesistimu kanye nokulungiswa okuphindaphindiwe, okwenza kube isixhumanisi esibalulekile ekukhetheni ihadiwe yamaphrojekthi ezimoto ezihlakaniphile.
Uhlu oluphelele lwe-3Rtablet lwamaphilisi aqinile afakwe emotweni luhlanganisa imininingwane ye-CAN eyodwa kanye ne-CAN ekabili enosayizi wesikrini ongu-5, 7 kanye no-10 amayintshi. Izici ezijwayelekile zifaka phakathi ukufaka i-voltage ebanzi engu-8–36 V, ukumelana nothuli namanzi kwe-IP67, ububanzi bokushisa kokusebenza obuphakathi kuka--10 °C kuya ku-65 °C, kanye nokumelana nokushaqeka nokudlidliza kwe-MIL-STD-810G. Izinsizakalo zokwenza ngokwezifiso ze-OEM kanye ne-ODM ziyatholakala. Singakwazi ukuklama izixazululo zehadiwe ezikhethekile ezenzelwe ukwakheka kwebhasi lemoto yakho, izimo zokusebenza kanye nezidingo zephrojekthi. Zizwe ukhululekile ukuxhumana nathi ukuthola ulwazi olwengeziwe.
