Yini i-CAN transceiver?

I-transceiver ye-CAN iyi-chip yokuguqulela efana no-232- noma 485 umsebenzi wayo oyinhloko ukuguqula isignali ye-TTL yesilawuli se-CAN ibe isignali ehlukile yebhasi le-CAN.

Yiziphi izimpawu ze-TTL zesilawuli se-CAN?

Izilawuli zanamuhla ze-CAN zivame ukuhlanganiswa ne-MCU futhi amasiginali wokudlulisa nokwamukela i-TTL amasignali ephinikhodi ye-MCU (ephezulu noma ephansi).

Ngaphambilini bekukhona abalawuli be-CAN abahlukene futhi inodi yenethiwekhi ye-CAN izoqukatha ama-chips amathathu: i-MCU chip, isilawuli se-CAN, kanye ne-CAN transceiver.Manje yizo ezimbili zokuqala ezihlanganiswe ndawonye (bheka isithombe ekuqaleni kwesihloko).

Izici zokufaka

Kuma-transceivers e-CAN ahlukanisiwe, okokufaka kubhekisela ikakhulukazi ezicini zokufakwayo ohlangothini lwesilawuli se-CAN lokuxhumeka, okuhlanganisa okokufaka kwamandla nokokufaka kwesignali.

Ngokuya nge-voltage yesixhumi esibonakalayo se-CAN yesilawuli kungakhethwa imojuli ye-CAN engu-3.3V noma engu-5V enikwe amandla.Ibanga elijwayelekile lokokufaka lemojula ehlukanisiwe ye-CAN yi-VCC ±5%, ikakhulukazi uma kucatshangelwa ukuthi ileveli yebhasi ye-CAN ingagcinwa ngaphakathi kwebanga lenani elivamile futhi yenze i-chip yesibili ye-CAN isebenze eduze kwevoltheji yokulethwa kwegama.

Kuma-chips e-CAN transceiver ahlukene, iphinikhodi ye-VIO ye-chip idinga ukuxhunywa ku-voltage yesithenjwa efanayo neleveli yesiginali ye-TXD ukuze ifane neleveli yesiginali, noma uma ingekho iphinikhodi ye-VIO, ileveli yesiginali kufanele igcinwe ihambisana ne-VCC. .Uma usebenzisa ama-transceiver ahlukanisiwe ochungechunge lwe-CTM kuyadingeka ukuze ufanise izinga lesiginali le-TXD ne-voltage yokuhlinzeka, okungukuthi i-3.3V ejwayelekile isixhumi esibonakalayo sesilawuli se-CAN noma isixhumi esibonakalayo se-CAN esijwayelekile se-5V.

Izici zokudlulisela

Izici zokudlulisa ze-CAN transceiver zisekelwe kumapharamitha amathathu: ukulibaziseka kokudlulisa, ukuthola ukubambezeleka, nokulibaziseka komjikelezo.

Uma sikhetha i-transceiver ye-CAN sicabanga ukuthi ipharamitha yokulibaziseka encane iba ngcono, kodwa yiziphi izinzuzo ezilethwa ukubambezeleka kokudlulisela okuncane futhi yiziphi izici ezikhawulela ukubambezeleka kokudlulisela kunethiwekhi ye-CAN?

Kuphrothokholi ye-CAN, indawo yokuthumela ithumela idatha nge-TXD kuyilapho i-RDX iqapha isimo sebhasi.Uma ibhithi yokuqapha ye-RDX ingafani nebhithi yokudlulisa, i-node ithola iphutha elincane.Uma lokho okubhekwayo endaweni yokulamula kungahambisani nokudluliswa kwangempela, i-node iyayeka ukudlulisa, okungukuthi kukhona ama-node amaningi ebhasini athumela idatha ngesikhathi esifanayo futhi i-node ayinikezwa kuqala ukudluliswa kwedatha.

Ngokufanayo, kukho kokubili ukuhlolwa kwedatha kanye nezingcezu zokuphendula ze-ACK, i-RDX iyadingeka ukuze kutholwe isimo sedatha yebhasi ngesikhathi sangempela.Isibonelo, ekuxhumaneni okujwayelekile kwenethiwekhi, ngaphandle kokungajwayelekile kwe-node, ukuze uthole impendulo ethembekile ye-ACK, kuyadingeka ukuqinisekisa ukuthi i-ACK bit idluliselwa kurejista ye-RDX yesilawuli ngesikhathi esithile, ngaphandle kwalokho, i-node yokuthumela izokwenza. thola iphutha lempendulo.Setha indawo yesampula ibe ngu-70% ku-1Mbps.Khona-ke isilawuli sizosampula i-ACK bit ku-70% wephoyinti lesikhathi kusukela ekuqaleni kwesikhathi esincane se-ACK, okungukuthi ukubambezeleka komjikelezo wenethiwekhi yonke ye-CAN kufanele kube ngaphansi kwama-700ns, kusukela ngesikhathi i-TXD ithumela, kuze kufike i-ACK. kancane itholwa kwa-RDX.

Kunethiwekhi eqhelile ye-CAN, le pharamitha inqunywa ngokuyinhloko ukubambezeleka kwe-isolator, ukubambezeleka komshayeli we-CAN, nobude bekhebula.Isikhathi esincane sokulibaziseka, ngakho-ke, sisiza ukusampula izingcezu ze-ACK ngokuthembekile nokwandisa ubude bebhasi.Umfanekiso wesi-2 ubonisa impendulo ye-ACK yamanodi amabili axhumana kusetshenziswa i-transceiver ye-CTM1051KAT.Isikhathi esijwayelekile sokulibaziseka esitholakala ku-transceiver sicishe sibe ngama-120ns.
