Uma ingekho enye idatha ebhasini le-CAN, isihlungi sozimele singase singasethwa. Ukuxhumana kungaqedwa. Uma kunenye idatha ebhasini, isihlungi sidinga ukusethwa. Hlukanisa umthombo wedatha etholwe idivayisi. Ngokwale ndlela. Ingabona ukuxhumana kwababungazi abaningi ebhasini. Idatha ethunyelwe ebhasini le-CAN ayidingi indlela yokuqinisekisa ye-CRC. Ukuqinisekiswa kwedatha ebhasini le-CAN sekuvele kunendlela yokuqinisekisa ephelele. Kule modi, idivayisi isekela ukuqinisekiswa kwe-Modbus nokudlulisela phambili, hhayi inkosi ye-Modbus noma isigqila, futhi umsebenzisi angaxhumana ngokulandela umthetho olandelwayo we-Modbus.
  • Iphrothokholi yokudlulisela ehlukaniswe ngezigaba
    Indlela yokuhlukanisa nokuhlela kabusha ulwazi ngobude obukhulu kunobude bedatha obukhulu bomlayezo we-CAN. Esimeni somlayezo we-CAN, "Idatha 1" isetshenziselwa ukuhlukanisa idatha yokuhlonza. Ifomethi yomlayezo wengxenye imi kanje, futhi okuqukethwe kwephrothokholi ye-Modbus edlulisiwe kwanele. Kusukela kubhayithi "yedatha engu-2", uma okuqukethwe kwephrothokholi kukukhulu kunamabhayithi angu-7, okuqukethwe kwephrothokholi okusele kuzoqhubeka nokuguqulwa ngale fomethi yezigaba kuze kuqedwe ukuguqulwa.
    • Umlayezo ohlukanisiwe tag: ikhombisa ukuthi umlayezo ungumyalezo ohlukene. Uma lokhu kuncane kungu-0, kusho umlayezo wesilinganiso esihlukile, futhi kungu-1 kusho ukuthi Okwefreyimu yomlayezo ohlukaniswe izingxenye.
    • Uhlobo lwesegimenti: Khombisa ukuthi yisigaba sokuqala, isigaba esiphakathi noma esokugcina.
    • Ikhawunta yengxenye: Uphawu lwengxenye ngayinye lubonisa inombolo yokulandelana kwesegimenti kuwo wonke umlayezo. Uma kuyinombolo yamasegimenti, inani lekhawunta yinombolo. Ngale ndlela, kungenzeka ukuqinisekisa ukuthi noma imaphi amasegimenti ashodayo lapho etholwa. I-5Bit isetshenziswa iyonke, futhi ububanzi bungu-0~31.
  • Guqula uzimele we-serial ukuze ube umlayezo
    I-serial interface yamukela iphrothokholi ejwayelekile ye-Modbus RTU, ngakho uhlaka lomsebenzisi ludinga kuphela ukuthobela le nqubo. Uma ifremu edlulisiwe ingahambisani nefomethi ye-Modbus RTU, imojuli izolahla ifremu eyamukelwe ngaphandle kokuyiguqula.
  • INGABE umlayezo kuzimele we-serial
    Ngedatha yephrothokholi ye-Modbus yebhasi le-CAN, asikho isidingo sokwenza ukuhlolwa kokuphindaphindeka kwe-cyclic (CRC16), imojula ithola ngokuya ngephrothokholi yokuhlukaniswa, futhi yengeza ngokuzenzakalelayo isheke lokuphindaphinda kwe-cyclic (CRC16) ngemuva kokuthola ukuhlaziywa kohlaka, futhi iguqule. ifake kuhlaka lwe-Modbus RTU ukuze uyithumele Ebhasini le-serial. Uma idatha etholiwe ingahambisani nephrothokholi yokuhlukanisa, iqoqo ledatha lizolahlwa ngaphandle kokuguqulwa.
    Ukuguqulwa example:
• Imodi yephrothokholi yangokwezifiso
  Kumelwe kube ifomethi yozimele we-serial ephelele evumelana nephrothokholi yangokwezifiso, futhi kufanele iqukathe wonke amafreyimu we-serial kumodi elungiselelwe umsebenzisi.
  Kunokuqukethwe, ngaphandle kwenkambu yedatha, uma okuqukethwe kwamanye amabhayithi kungalungile, lolu hlaka ngeke luthunyelwe ngempumelelo. Okuqukethwe kohlaka lomkhiqizo: unhlokweni wozimele, ubude bozimele, ulwazi lozimele, i-ID yozimele, inkambu yedatha, isiphetho sozimele.
  Qaphela: Kule modi, i-ID yozimele kanye nohlobo lozimele olulungiselelwe umsebenzisi akuvumelekile, futhi idatha izodluliswa ngokuya ngefomethi kuzimele we-serial.
  • Guqula uzimele we-serial ube umlayezo we-CAN
    Ifomethi yozimele we-serial kufanele ihambisane nefomethi yozimele eshiwo. Ngenxa yokuthi ifomethi yohlaka lwe-CAN isekelwe emilayezweni, ifomethi yozimele we-serial isekelwe ekudlulisweni kwebhayithi. Ngakho-ke, ukuze kuvunyelwe abasebenzisi ukuthi basebenzise i-CAN-ibhasi ngendlela efanele, ifomethi yefreyimu ye-serial ihanjiswa eduze nefomethi yefreyimu ye-CAN, futhi ukuqala nokuphela kohlaka kucaciswe kuhlaka lwe-serial, okungukuthi, “ikhanda lozimele” kanye “nokuphela kohlaka” kumyalo we-AT. , Abasebenzisi bangazilungiselela ngokwabo. Ubude bozimele bubhekisela kubude obusuka ekuqaleni kolwazi lozimele kuya ekupheleni kwedatha yokugcina, okungabandakanyi isiphetho sozimele we-serial. Ulwazi lohlaka luhlukaniswe lwaba ozimele abanwetshiwe kanye nozimele abajwayelekile. Uhlaka olujwayelekile lulungiswa njengo-0x00, futhi uhlaka olunwetshiwe lulungiswa njengo-0x80, oluhlukile ekuguquleni okusobala kanye nokuguqulwa okusobala okunokuhlonza. Ekuguquleni kwephrothokholi yangokwezifiso, kungakhathaliseki ubude bedatha obuqukethwe kunkambu yedatha yozimele ngamunye Kungakanani, okuqukethwe kolwazi lozimele okulungisiwe. Uma uhlobo lozimele kuwuhlaka olujwayelekile (0x00), amabhayithi amabili okugcina ohlobo lozimele amelela i-ID yozimele, enohlelo oluphezulu kuqala; uma ulwazi lohlaka luwuhlaka olunwetshiwe (0x80), amabhayithi okugcina angu-4 ohlobo lozimele amelela i-ID yohlaka, lapho izinga eliphezulu kuqala
    Qaphela: Ekuguquleni kwephrothokholi yangokwezifiso, kungakhathaliseki ubude bedatha obuqukethwe kunkambu yedatha yozimele ngamunye, okuqukethwe kolwazi lozimele kuyalungiswa. Ilungiswe njengohlaka olujwayelekile (0x00) noma uhlaka olunwetshiwe (0x80). I-ID yozimele idinga ukuhambisana nobubanzi be-ID, ngaphandle kwalokho i-ID ingase ibe nephutha.
  • Guqula umlayezo we-CAN ube uzimele we-serial
    Umlayezo webhasi we-CAN uthola ifremu bese udlulisela phambili uhlaka. Imojula izoguqula idatha kunkambu yedatha yomlayezo we-CAN ngokushintshana, futhi ngesikhathi esifanayo yengeze unhlokweni wozimele, ubude bozimele, ulwazi lozimele kanye nenye idatha kufreyimu ye-serial, empeleni okuwuzimele wesiriyeli Dlulisa uhlobo lokuhlehla lomlayezo we-CAN. .
    Guqula imilayezo ye-CAN ibe ozimele be-serial
    Ukuguqulwa example:
    Uhlaka lwe-serial oluya kumlayezo we-CAN (iphrothokholi yangokwezifiso).
    CAN amapharamitha wokumisa amisiwe kulesi sifanisoample.
    Imodi yokuguqula: iphrothokholi yangokwezifiso, unhlokweni wozimele AA, ukuphela kozimele: FF, isiqondiso sokuguqulwa: i-bidirectional.
    I-ID yohlaka: Asikho isidingo sokumisa, Uhlobo lozimele: Asikho isidingo sokumisa, idatha ngaphambi nangemuva kokuguqulwa imi kanje. INGABE umlayezo we-serial frame: uhlobo oluphambene lozimele we-serial kumlayezo we-CAN.
