Chii chinonzi CAN transceiver?
A CAN transceiver ndeye 232- kana 485-yakafanana inoshandura chip iyo basa guru nderekushandura TTL chiratidzo cheCAN controller kuita chiratidzo chekusiyanisa cheCAN bhazi.
Chii CAN controller TTL masaini?
Mazuva ano maCAN controllers anowanzo kusanganiswa neMCU uye kutapurirana kwavo uye kugamuchira masaini eTTL ndiyo MCU pini (yakakwirira kana yakaderera) masaini.
Pakutanga kwaive neakaparadzana CAN controllers uye CAN network node yaizova nemachipisi matatu: MCU chip, CAN controller, uye CAN transceiver.Iye zvino ndiwo maviri ekutanga akabatanidzwa pamwechete (ona mufananidzo uri pakutanga kwechinyorwa).
Kupinza maitiro
Kune ega eCAN transceivers, iyo yekuisa inoreva zvakanyanya kune ekuisa maitiro paCAN controller divi rekubatanidza, inosanganisira iyo yekuisa simba uye chiratidzo chekuisa.
Zvichienderana neCAN interface voltage yemutongi 3.3V kana 5V powered CAN module inogona kusarudzwa.Iyo yakajairwa yekuisa huwandu hweiyo yakasarudzika CAN module ndeye VCC ± 5%, kunyanya tichifunga kuti iyo CAN bhazi nhanho inogona kuchengetwa mukati meyakajairika kukosha renji uye zvakare kuita kuti yechipiri CAN chip ishande yakatenderedza yezita rekupa voltage.
Kune akapatsanurwa CAN transceiver machipisi, iyo VIO pini yechip inoda kubatanidzwa kune yakafanana referensi voltage seiyo TXD chiratidzo chiyero kuti ienderane nechiratidzo chechiratidzo, kana kana pasina VIO pini, iyo chiratidzo chechiratidzo chinofanira kuchengetedzwa zvinoenderana neVCC. .Paunenge uchishandisa CTM akatevedzana akasarudzika transceivers zvinodikanwa kuti uenderane nechiyero chechiratidzo cheTXD nemagetsi ekupa, kureva 3.3V yakajairwa CAN controller interface kana 5V yakajairwa CAN controller interface.
Transmission maitiro
Maitiro ekutapurirana eCAN transceiver akavakirwa pamatanho matatu: kufambisa kunonoka, kugamuchira kunonoka, uye kunonoka kutenderera.
Pakusarudza CAN transceiver isu tinofungidzira kuti iyo diki yekunonoka parameter iri nani, asi ndeapi mabhenefiti anounza kunonoka kutapurirana uye zvinhu zvipi zvinomisa kunonoka kutapurirana muCAN network?
MuCAN protocol, iyo node yekutumira inotumira data kuburikidza neTXD nepo RDX ichitarisa mamiriro ebhazi.Kana iyo RDX yekutarisa bhiti isingaenderane neinotapurirana bhiti, iyo node inoona zvishoma kukanganisa.Kana izvo zvinotariswa mumunda wekupokana zvisingaenderane neiyo chaiyo kutapurirana, iyo node inomira kutumira, kureva kuti kune akawanda nodes pabhazi kutumira data panguva imwe chete uye node haina kupihwa kufambiswa kwedata pakutanga.
Saizvozvo, mune zvese cheki data uye ACK mhinduro mabits, iyo RDX inodikanwa kuti uwane iyo data mamiriro ebhazi munguva chaiyo-nguva.Semuenzaniso, mune yakajairika network kutaurirana, kusasanganisa node abnormalities, kuti ugamuchire nekuvimbika mhinduro yeACK, zvinodikanwa kuve nechokwadi kuti iyo ACK bit inoendeswa kune iyo RDX rejista yemutungamiriri mukati meimwe nguva, kana zvisina kudaro, iyo node yekutumira ichaita. tsvaga mhinduro.Isa iyo sampling chinzvimbo ku70% pa1Mbps.Zvadaro mutongi anozotora ACK bit pa70% yenguva kubva pakutanga kweACK bit time, kureva kutenderera kunonoka kwese CAN network kunofanira kunge iri pasi pe700ns, kubva panguva iyo TXD inotumira, kusvika ACK. bit inogamuchirwa paRDX.
Mune yakasarudzika CAN network, iyi paramende inonyanya kutariswa nekunonoka kwekuzviparadzanisa nevamwe, kunonoka mutyairi weCAN, uye kureba kwetambo.Nguva diki yekunonoka, saka, inobatsira kuenzanisa iyo ACK bits zvakavimbika uye kuwedzera urefu hwebhazi.Mufananidzo 2 unoratidza mhinduro yeACK yemanode maviri achitaurirana achishandisa CTM1051KAT transceiver.Iyo yakajairika nguva yekunonoka yakagara kune transceiver ingangoita 120ns.
