Transceiver ea CAN ke eng?
CAN transceiver ke 232- kapa 485-like converter chip eo mosebetsi oa eona o ka sehloohong e leng ho fetola lets'oao la TTL la molaoli oa CAN hore e be lets'oao le fapaneng la bese ea CAN.
Ke matšoao afe a CAN controller TTL?
Balaoli ba kajeno ba CAN ka kakaretso ba kopantsoe le MCU mme matšoao a bona a ho fetisa le ho amohela TTL ke matshwao a MCU pin (e phahameng kapa a tlase).
Pejana ho ne ho e-na le balaoli ba CAN ba arohaneng le node ea marang-rang ea CAN e ne e tla ba le litsupa tse tharo: chip ea MCU, molaoli oa CAN, le transceiver ea CAN.Hona joale ke tse peli tsa pele tse kopantsoeng hammoho (sheba setšoantšo se qalong ea sehlooho).
Litšobotsi tsa ho kenya
Bakeng sa li-transceivers tse ka thōko tsa CAN, ho kenya letsoho ho bolela haholo-holo ho litšoaneleho tsa ho kenya ka lehlakoreng la molaoli oa CAN oa khokahanyo, tse nang le matla a ho kenya le ho kenya letsoho.
Ho itšetlehile ka motlakase oa CAN interface ea molaoli, mochine oa CAN o nang le matla a 3.3V kapa 5V o ka khethoa.Mokhoa o tloaelehileng oa ho kenya mochine oa CAN o ka thōko ke VCC ± 5%, haholo-holo ho nahanoa hore boemo ba libese ba CAN bo ka bolokoa ka har'a mefuta e tloaelehileng ea boleng le ho etsa hore chip ea CAN ea bobeli e sebetse ho pota-pota motlakase oa phepelo ea lebitso.
Bakeng sa li-chips tse arohaneng tsa CAN transceiver, pini ea VIO ea chip e hloka ho hokahanngoa le motlakase o tšoanang oa litšupiso joalo ka boemo ba lets'oao la TXD ho tsamaisana le boemo ba lets'oao, kapa haeba ho se na phini ea VIO, boemo ba lets'oao bo lokela ho bolokoa tumellanong le VCC. .Ha u sebelisa li-transceivers tse arohaneng tsa CTM hoa hlokahala ho tsamaisana le boemo ba pontšo ea TXD le motlakase oa phepelo, ke hore 3.3V standard CAN controller interface kapa 5V standard CAN controller interface.
Litšobotsi tsa phetiso
Litšobotsi tsa phetiso ea transceiver ea CAN li ipapisitse le liparamente tse tharo: tieho ea ho fetisa, ho amohela tieho, le ho lieha ha potoloho.
Ha re khetha transceiver ea CAN re nka hore parameter e nyane ea ho lieha e molemo, empa ke melemo efe e tlisoang ke ho lieha ha phetisetso e nyane mme ke lintlha life tse fokotsang ho lieha ha phetisetso ho netweke ea CAN?
Ho protocol ea CAN, node ea ho romella e romella data ka TXD ha RDX e lekola boemo ba libese.Haeba sesebelisoa sa RDX se sa tsamaisane le sekhahla sa phetisetso, node e bona phoso e nyane.Haeba se hlokometsoeng tšimong ea arbitration se sa lumellane le phetisetso ea sebele, node e emisa ho fetisa, ke hore ho na le li-node tse ngata ka beseng e romellang data ka nako e le 'ngoe' me node ha e fuoe pele ho fetisa data.
Ka mokhoa o ts'oanang, ho cheke ea data le likotoana tsa karabelo tsa ACK, RDX ea hlokahala ho fumana boemo ba data ba bese ka nako ea nnete.Ka mohlala, puisanong e tloaelehileng ea marang-rang, ntle le mekhoa e sa tloaelehang ea li-node, e le hore u fumane karabo ea ACK ka botšepehi, hoa hlokahala ho netefatsa hore ACK bit e fetisetsoa ho ngoliso ea RDX ea molaoli ka nako e itseng, ho seng joalo, node ea ho romela e tla. lemoha phoso ea karabo.Beha boemo ba sampole ho 70% ho 1Mbps.Joale molaoli o tla etsa mohlala oa ACK bit ho 70% ea nako ea nako ho tloha qalong ea ACK bit time, ke hore, ho lieha ha potoloho ea marang-rang a CAN ho lokela ho ba tlase ho 700ns, ho tloha nakong eo TXD e romelang, ho fihlela ACK. bit e amoheloa ho RDX.
Ho netweke e ka thoko ya CAN, paramethara ena e laolwa haholo ke tieho ya ho itšehla thajana, tieho ya mokganni wa CAN, le bolelele ba thapo.Nako e nyane ea ho lieha, ka hona, e thusa ho etsa sampole likotoana tsa ACK ka ts'epo le ho eketsa bolelele ba libese.Setšoantšo sa 2 se bontša karabelo ea ACK ea li-node tse peli tse buisanang ho sebelisa transceiver ea CTM1051KAT.Nako e tloaelehileng ea tieho ea tlhaho ho transceiver e ka ba 120ns.
