TCAN1042HGVDRQ1 SOP8 Hoʻokaʻawale ʻia nā mea uila hou i hoʻāʻo ʻia i ka chip kaapuni hoʻohui ʻia IC TCAN1042HGVDRQ1

ʻO PHY kahi hōkū e piʻi aʻe ana ma nā noi kaʻa (e like me T-BOX) no ka hoʻouna ʻana i ka hōʻailona wikiwiki, ʻoiai ʻo CAN he lālā koʻikoʻi no ka hoʻouna ʻana i ka hōʻailona haʻahaʻa.Pono paha ka T-BOX o ka wā e hiki mai ana e hōʻike i ka ID kaʻa, ka hoʻohana wahie, mileage, trajectory, kūlana kaʻa (nā kukui puka a me ka puka makani, ka aila, ka wai a me ka uila, ka wikiwiki ʻole, etc.), ka wikiwiki, kahi, nā ʻano kaʻa. , hoʻonohonoho kaʻa, a me nā mea ʻē aʻe ma ka pūnaewele kaʻa a me ka pūnaewele kaʻa kaʻa, a ke hilinaʻi nei kēia mau ʻikepili haʻahaʻa haʻahaʻa i ke ʻano nui o kēia ʻatikala, CAN.

Ua hoʻolauna ʻia ke kaʻa kaʻa CAN e Bosch ma Kelemānia i ka makahiki 1980 a ua lilo ia i mea hoʻohui a koʻikoʻi o ke kaʻa.No ka hoʻokō ʻana i nā koi like ʻole o nā ʻōnaehana kaʻa, ua hoʻokaʻawale ʻia ke kaʻa CAN i CAN kiʻekiʻe a me CAN haʻahaʻa.Hoʻohana nui ʻia ʻo CAN kiʻekiʻe no ka mālama ʻana i nā ʻōnaehana mana e koi ana i ka hana kiʻekiʻe o ka manawa maoli, e like me nā mīkini, nā hoʻoili maʻalahi, a me nā puʻupuʻu mea kani.Hoʻohana nui ʻia ka CAN haʻahaʻa haʻahaʻa no ka mālama ʻana i nā ʻōnaehana hōʻoluʻolu a me nā ʻōnaehana kino e pono ai ka hana ʻoi aku ka manawa maoli, e like me ka hoʻokele air conditioning, hoʻoponopono noho, hoʻokiʻekiʻe pukaaniani, a pēlā aku.Ma kēia ʻatikala, e nānā mākou i ka wikiwiki wikiwiki CAN.

ʻOiai ʻo CAN kahi ʻenehana ʻoi loa, ke kū nei ʻo ia i nā pilikia i nā noi automotive.Ma kēia pepa, e nānā kākou i kekahi o nā pilikia a CAN e kū nei a hoʻolauna i nā ʻenehana kūpono e hoʻoponopono ai.ʻO ka mea hope loa, e wehewehe ʻia nā mea maikaʻi o nā noi CAN a TI a me kāna mau huahana "hardcore".

Paʻa hoʻokahi: ʻO ka loiloi hana EMI

Ke piʻi nei ka nui o nā mea uila i nā kaʻa i kēlā me kēia makahiki, ke koi ʻia nei ka hoʻohālikelike electromagnetic (EMC) o nā ʻoihana i loko o nā kaʻa, no ka mea, ke hoʻohui ʻia nā ʻāpana āpau i ka ʻōnaehana like, pono ia e hōʻoia i ka hana ʻana o nā subsystems e like me ka mea i manaʻo ʻia. , ʻoiai ke alo o nā kaiapuni walaʻau.ʻO kekahi o nā pilikia nui e kū nei e CAN, ʻo ia ka ʻoi aku o ka hoʻokuʻu ʻana i hana ʻia e ka walaʻau maʻamau.

ʻO ke kūpono, hoʻohana ʻo CAN i ka hoʻoili loulou ʻokoʻa no ka pale ʻana i ka hui ʻana o ka walaʻau.I ka hoʻomaʻamaʻa naʻe, ʻaʻole kūpono nā transceivers CAN a hiki i kahi asymmetry liʻiliʻi loa ma waena o CANH a me CANL hiki ke hana i kahi hōʻailona ʻokoʻa like, kahi e hoʻopau ai ka ʻāpana mode maʻamau o CAN (ʻo ia hoʻi ka awelika o CANH a me CANL) ʻĀpana DC a lilo i ka leo pili i ka ʻikepili.ʻElua ʻano o ke kaulike ʻole i hopena i kēia walaʻau: ka leo haʻahaʻa haʻahaʻa i hoʻokumu ʻia e ka like ʻole ma waena o ke kūlana paʻa maʻamau o ke ʻano maʻamau i nā mokuʻāina nui a me ka recessive, nona ka laulā ākea o nā ʻano walaʻau a ʻike ʻia ma ke ʻano he ʻano like ʻole. i hoʻokaʻawale i nā laina spectral discrete;a me ka leo alapine kiʻekiʻe ma muli o ka ʻokoʻa o ka manawa ma waena o ka hoʻololi ʻana ma waena o ka mana a me ka recessive CANH a me CANL, ʻo ia hoʻi nā puʻupuʻu pōkole a me nā haunaele i hana ʻia e nā lele lihi ʻikepili.Hōʻike ka kiʻi 1 ma lalo nei i kahi laʻana o ka CAN transceiver maʻamau ka leo maʻamau.ʻO ka ʻeleʻele (kanela 1) ʻo CANH, ʻo ka poni (kanila 2) ʻo CANL a ʻo ka ʻōmaʻomaʻo e hōʻike ana i ka huina o CANH a me CANL, ʻo ka waiwai o ia mea ua like me ka pālua o ka volta mode maʻamau i kahi manawa i hāʻawi ʻia.
