He aha te mea CAN-Bus, a he aha te mea te reira hoki?

I te kau, tata nga motokā hou kaimahi e i runga i-papa rorohiko, pūnaha ABS, EBD, te mana matapihi, me te maha atu pūrere hiko. Na, ka taea e tenei tikanga whakahaere aunoa kore anake, engari ano hoki pūnaha whāhauhau, me te waipēhi. e kore e taea te mahi i Ahakoa te pūkaha, kahore te hikohiko. Ko te pūrere motuhake - CAN-pahi. Ko te pā ana ki kōrero i te reira i teie mahana.

Ko te hītori o te takanga

puta te ariā o te CAN-pahi i roto i te 80 o te rau tau whakamutunga. Na ka kua whakawhanakehia te kamupene pai-mohiotia Tiamana "Bosch" i roto i te mahi tahi ki te u "Intel" he pūrere mamati hou mō te tuku raraunga, e kiia nei ko te Controller Area Whatunga.

He aha ia e taea te mahi?

kia whātuitui tenei pahi katoa o nga pūoko, me whakahaere nga poraka e te hunga i roto i te waka. TAEA taea te hono ki te immoblayzerom, pūnaha SRS, ESP, wae mana pūkaha hiko, tuku, me ara airbags. I tua atu, whakapā atu te tupare te ki te pūoko whakatārewatanga, te pūnaha maukati pokapū , me te mana āhuarangi. E hono enei tikanga katoa i roto i te aratau tonu-Matarua ki te auau raraunga ki runga ki te 1 Mbit / s.

CAN-pahi: Whakamārama me ngā āhuatanga o te pūrere

Hoki tona taumahinga katoa, Kei tenei tikanga o rua noa waea me te maramara kotahi. I mua, ki te hono i te pūoko katoa tukua ki CAN-pahi tekau kōhao. A, ki te i roto i te 80 tau mo ia ahokore tuku tetahi anake tohu, ka inaianei tae tenei uara rau.

Ko rerekē i roto i taua kua reira te mahi o te tūhono ki te waea pūkoro hoki CAN tupare ki hou. mowhiti kī Hiko, mahi te mahi o te kī pātīmata, kia hoki kia hono ki te kōwae me te farii i ngā mōhiohio i te wae mana pūkaha.

He mea nui hoki kia tāutu tenei taputapu te raruraru i roto i te mahi o te taputapu mīhini me i roto i ētahi wā whakakore ratou. Ko reira whakaritea watea i raweketia, ka he hoapā pai mātao. CAN-pahi he hātepe rawa uaua. Raraunga tuku e te roto i te reira patu, tonu puta ki ngā pikitia. kaimahi te mōhiohio rite te aratohu-waea 2 o pōkai takirua. He hoki hua o te muka, engari he ratou iti tōtika i roto i te mahi, na reira, e kore e pera nui noa rite te kōwhiringa tuatahi. Te iti rawa pea ki te whakatau CAN-pahi, e whakawhiti te mōhiohio mā reo irirangi ranei hihi pōkākā.

Taumahinga me te mahi

Ki te whakapai ake i te mahi o tenei pūrere, maha whakapoto kaiwhakanao te roa o te waea. Ki te mea ka waiho i te roa tapeke o te pahi iti iho i te 10 mita, ka whakanui i te auau mōhiohio ake ki te 2 megabits ia rua. Ko te tikanga i tenei tere tikanga 64 whakawhiti raraunga ki pūoko hiko me pūmana. Ki te te hono te pahi ki te maha nui o ngā pūrere hanga ētahi arahiko mō te fariiraa, me te whakawhitihia mōhiohio.

Ki te ka whakawhanakehia te CAN-Bus atu, pea ka hohoro tāuta reira tino i runga i waka, me taraka katoa, tae atu hoki kāinga.
