Kodi CAN transceiver ndi chiyani?
CAN transceiver ndi 232- kapena 485-monga converter chip yomwe ntchito yake yaikulu ndi kutembenuza chizindikiro cha TTL cha CAN controller kukhala chizindikiro chosiyana cha basi ya CAN.
Kodi CAN controller TTL imawonetsa chiyani?
Olamulira amakono a CAN nthawi zambiri amaphatikizidwa ndi MCU ndipo kutumiza kwawo ndikulandila ma sign a TTL ndi ma pini a MCU (apamwamba kapena otsika).
M'mbuyomu panali olamulira osiyana a CAN ndipo nodi ya netiweki ya CAN ingakhale ndi tchipisi ta MCU, CAN controller, ndi CAN transceiver.Tsopano ndi ziwiri zoyambirira zomwe zimagwirizanitsidwa pamodzi (onani chithunzi kumayambiriro kwa nkhaniyi).
Makhalidwe olowetsa
Kwa ma transceivers odzipatula a CAN, zolowetsazo zimatanthawuza makamaka zomwe zimalowetsedwera kumbali ya CAN yolumikizira, yomwe imakhala ndi kulowetsa mphamvu ndi kuyika kwa chizindikiro.
Kutengera mawonekedwe a CAN mawonekedwe amagetsi a wowongolera gawo la 3.3V kapena 5V loyendetsedwa ndi CAN lingasankhidwe.Kuyika kwanthawi zonse kwa gawo la CAN lakutali ndi VCC ± 5%, makamaka poganizira kuti mulingo wa basi ya CAN ukhoza kusungidwa mumtundu wamtengo wapatali ndikupangitsanso chipangizo chachiwiri cha CAN kugwira ntchito mozungulira voteji yodziwika bwino.
Kwa tchipisi tapadera ta CAN transceiver, pini ya VIO ya chip iyenera kulumikizidwa ndi voliyumu yofananira monga mulingo wa siginecha wa TXD kuti ufanane ndi mulingo wazizindikiro, kapena ngati palibe pini ya VIO, mulingo wazizindikiro uyenera kusungidwa mogwirizana ndi VCC. .Mukamagwiritsa ntchito ma transceivers odzipatula a CTM m'pofunika kuti mufanane ndi mlingo wa chizindikiro cha TXD ndi magetsi operekera, mwachitsanzo 3.3V muyezo CAN mawonekedwe olamulira kapena 5V muyezo CAN wolamulira mawonekedwe.
Makhalidwe opatsirana
Makhalidwe opatsirana a CAN transceiver amachokera pazigawo zitatu: kufalitsa kuchedwa, kulandira kuchedwa, ndi kuchedwa kwa kuzungulira.
Posankha transceiver ya CAN timaganiza kuti kuchedwetsa kocheperako kumakhala bwinoko, koma ndi phindu lanji lomwe kuchedwetsa kumabweretsa kuchedwa kwapang'ono ndipo ndi zinthu ziti zomwe zimachepetsa kuchedwa kwapaintaneti ya CAN?
Mu protocol ya CAN, node yotumiza imatumiza deta kudzera pa TXD pomwe RDX imayang'anira mabasi.Ngati chowunikira cha RDX sichikufanana ndi cholumikizira, node imazindikira zolakwika pang'ono.Ngati zomwe zimayang'aniridwa m'munda wa arbitration sizikufanana ndi kufalitsa kwenikweni, mfundoyi imasiya kutumiza, mwachitsanzo, pali ma node angapo pa basi kutumiza deta panthawi imodzimodziyo ndipo nodeyo sapatsidwa patsogolo kutumiza deta.
Momwemonso, muzofufuza zonse za data ndi ma ACK mayankho ma bits, RDX imafunikanso kupeza momwe mabasi alili munthawi yeniyeni.Mwachitsanzo, mukulankhulana kwapaintaneti wamba, kupatula zolakwika za node, kuti mulandire yankho la ACK modalirika, ndikofunikira kuwonetsetsa kuti ACK bit imasamutsidwa ku kaundula wa RDX wa woyang'anira mkati mwa nthawi inayake, apo ayi, node yotumiza itero. zindikirani cholakwika cha yankho.Khazikitsani sampuli kukhala 70% pa 1Mbps.Ndiye wolamulirayo adzayesa ACK pang'ono pa 70% ya nthawi kuyambira pachiyambi cha ACK bit time, mwachitsanzo, kuchedwa kwapaintaneti yonse ya CAN kuyenera kukhala osachepera 700ns, kuyambira nthawi yomwe TXD imatumiza, mpaka ACK. pang'ono imalandiridwa ku RDX.
Mu netiweki yapayokha ya CAN, chizindikirochi chimatsimikiziridwa makamaka ndi kuchedwa kwa odzipatula, kuchedwa kwa dalaivala wa CAN, ndi kutalika kwa chingwe.Nthawi yochedwa pang'ono, motero, imathandizira kuyesa ma bits a ACK modalirika ndikuwonjezera kutalika kwa basi.Chithunzi 2 chikuwonetsa kuyankha kwa ACK kwa node ziwiri zolumikizana pogwiritsa ntchito transceiver ya CTM1051KAT.Nthawi yochedwa yokhazikika kwa transceiver ndi pafupifupi 120ns.
