I-TCAN1042HGVDRQ1 SOP8 Ukusatshalaliswa Kwezingxenye Ze-elekthronikhi Okusha Kwangempela Kwangempela Kwahlolwa I-Circuit Chip IC TCAN1042HGVDRQ1

I-PHY iyinkanyezi evelayo ezinhlelweni zemoto (ezifana ne-T-BOX) yokudlulisa isignali enesivinini esikhulu, kuyilapho i-CAN iseyilungu elibalulekile lokudluliswa kwesignali enesivinini esiphansi.I-T-BOX yesikhathi esizayo cishe izodinga ukubonisa i-ID yemoto, ukusetshenziswa kukaphethiloli, imayela, i-trajectory, isimo semoto (izibani zezicabha namawindi, uwoyela, amanzi nogesi, isivinini sokungenzi lutho, njll.), isivinini, indawo, izici zemoto. , ukulungiselelwa kwemoto, njll. kunethiwekhi yemoto kanye nenethiwekhi yemoto yeselula, futhi lokhu kudluliselwa kwedatha okunesivinini esiphansi kuncike kumlingisi oyinhloko walesi sihloko, i-CAN.

Ibhasi le-CAN lethulwa ngabakwaBosch eJalimane ngeminyaka yawo-1980 futhi selokhu laba ingxenye ebalulekile nebalulekile yemoto.Ukuze kuhlangatshezwane nezidingo ezihlukene zamasistimu emoto, ibhasi le-CAN lihlukaniswe nge-CAN enesivinini esiphezulu kanye ne-CAN enesivinini esiphansi.I-CAN enesivinini esikhulu isetshenziselwa kakhulu ukulawula amasistimu kagesi adinga ukusebenza kwesikhathi sangempela okuphezulu, njengezinjini, ukuhanjiswa okuzenzakalelayo, namaqoqo wezinsimbi.I-low-speed CAN isetshenziselwa kakhulu ukulawula izinhlelo zokunethezeka nezinhlelo zomzimba ezidinga ukusebenza kwesikhathi sangempela okuncane, njengokulawula isimo somoya, ukulungiswa kwesihlalo, ukuphakamisa amawindi, njalonjalo.Kulesi sihloko, sizogxila ku-CAN enesivinini esikhulu.

Yize i-CAN iwubuchwepheshe obuvuthwe kakhulu, isabhekene nezinselelo ezinhlelweni zezimoto.Kuleli phepha, sizobheka ezinye zezinselelo i-CAN ebhekene nazo futhi sethule ubuchwepheshe obufanele bokubhekana nazo.Okokugcina, izinzuzo zezinhlelo zokusebenza ze-TI's CAN kanye nemikhiqizo yayo "eqinile" izochazwa ngokuningiliziwe.

Inselelo yokuqala: Ukwenziwa ngcono kokusebenza kwe-EMI

Njengoba ukuminyana kwama-elekthronikhi ezimotweni kukhula unyaka nonyaka, ukuhambelana kwe-electromagnetic (EMC) yamanethiwekhi ezimoto kudingekile kakhulu, ngoba lapho zonke izingxenye zihlanganiswa ohlelweni olufanayo, kubalulekile ukuqinisekisa ukuthi amasistimu asebenza njengoba kulindelekile. , ngisho nalapho kubhekene nezindawo ezinomsindo.Enye yezinselelo ezinkulu i-CAN ebhekene nazo ukweqiwa kwezisi ezikhishwayo ezibangelwa umsindo wemodi evamile.

Ngokufanelekile, i-CAN isebenzisa ukudluliswa kwesixhumanisi esihlukile ukuvimbela ukuhlangana komsindo wangaphandle.Nokho, ekusebenzeni, ama-transceivers e-CAN awalungile futhi ngisho nokulingana okuncane kakhulu phakathi kwe-CANH ne-CANL kungaveza isignali ehambisanayo yokuhlukanisa, okubangela ingxenye yemodi evamile ye-CAN (okungukuthi isilinganiso se-CANH ne-CANL) ukuba siyeke ukuba njalo. Ingxenye ye-DC futhi ibe nomsindo oncike kudatha.Kunezinhlobo ezimbili zokungalingani eziholela kulo msindo: umsindo wefrikhwensi ephansi obangelwa ukungafani phakathi kwezinga lemodi evamile yesimo esizinzile ezimeni ezibusayo nezinciphayo, ezinobubanzi obubanzi befrikhwensi yamaphethini womsindo futhi obonakala njengochungechunge lokufana. imigqa ye-spectral ehlukanisiwe;nomsindo wefrikhwensi ephezulu obangelwa umehluko wesikhathi phakathi koshintsho phakathi kwe-CANH enamandla nerecessive kanye ne-CANL, equkethe ama-pulses amafushane kanye nokuphazamiseka okukhiqizwa ukweqa konqenqema lwedatha.Umfanekiso 1 ngezansi ubonisa isibonelo somsindo wemodi evamile ye-CAN transceiver.Okumnyama (isiteshi 1) yi-CANH, okunsomi (isiteshi 2) yi-CANL futhi okuluhlaza kukhombisa isamba se-CANH ne-CANL, inani layo elilingana nevoltheji yemodi evamile kabili endaweni ethile ngesikhathi.
