I-PHY yinkwenkwezi ekhulayo kwizicelo zemoto (ezifana ne-T-BOX) yokuhanjiswa kwesignali yesantya esiphezulu, ngelixa i-CAN iselilungu eliyimfuneko kwi-speed-speed signal transmission.I-T-BOX yexesha elizayo iya kufuneka ukuba ibonise i-ID yesithuthi, ukusetyenziswa kwe-fuel, i-mileage, i-trajectory, imeko yesithuthi (umnyango kunye nezibane zefestile, i-oyile, amanzi kunye nombane, isantya esingenamsebenzi, njl.), isantya, indawo, iimpawu zesithuthi. , ukucwangciswa kwesithuthi, njl njl kuthungelwano lwemoto kunye nenethiwekhi yemoto ehambayo, kwaye ezi nkcukacha zokuhanjiswa kwedatha ezisezantsi zixhomekeke kumlinganiswa oyintloko weli nqaku, i-CAN.

Ibhasi yeCAN yaziswa nguBosch eJamani ngeminyaka yoo-1980 kwaye sele iyinxalenye ebalulekileyo nebalulekileyo yemoto.Ukuhlangabezana neemfuno ezahlukeneyo zeenkqubo zezithuthi, ibhasi ye-CAN ihlulwe kwi-CAN ephezulu kunye ne-CAN ephantsi.I-CAN enesantya esiphezulu isetyenziselwa ukulawula iinkqubo zamandla ezifuna ukusebenza kwexesha lokwenyani eliphezulu, njengeenjini, ukuhanjiswa ngokuzenzekelayo, kunye namaqela ezixhobo.I-CAN yesantya ephantsi isetyenziselwa ukulawula iinkqubo zokuthuthuzela kunye neenkqubo zomzimba ezifuna ukusebenza okungaphantsi kwexesha langempela, njengokulawula umoya, ukulungiswa kwesihlalo, ukuphakamisa ifestile, njalo njalo.Kweli nqaku, siza kugxila kwi-CAN ephezulu.

Nangona i-CAN iyitekhnoloji ekhule kakhulu, isajongene nemingeni kwizicelo zeemoto.Kweli phepha, siza kujonga eminye imingeni i-CAN ejongene nayo kwaye sazise ubuchwephesha obufanelekileyo ukuyilungisa.Okokugqibela, izibonelelo ze-TI's CAN izicelo kunye neemveliso zayo "ezinzima" ziya kuchazwa ngokweenkcukacha.

Umngeni wokuqala: Ukwenziwa komsebenzi we-EMI

Njengoko ubuninzi bezinto zombane ezimotweni bukhula minyaka le, ukuhambelana kwe-electromagnetic (EMC) yothungelwano lwemoto kufunwa nangakumbi, kuba xa onke amacandelo edityanisiwe kwinkqubo enye, kubalulekile ukuqinisekisa ukuba iinkqubo ezingaphantsi zisebenza njengoko kulindelekile. , naxa kukho ingxolo yendawo engqongileyo.Omnye wemingeni emikhulu ejongene ne-CAN kukugqithiswa kwezinto ezikhutshwayo ezibangelwa yingxolo yemo eqhelekileyo.

Ngokufanelekileyo, i-CAN isebenzisa ukuhanjiswa kwekhonkco eyahlukileyo ukuthintela ukudityaniswa kwengxolo yangaphandle.Nangona kunjalo, i-CAN transceivers ayifanelekanga kwaye i-asymmetry encinci kakhulu phakathi kwe-CANH kunye ne-CANL inokuvelisa uphawu oluhambelanayo oluhambelanayo, olubangela ukuba icandelo lemowudi eqhelekileyo ye-CAN (oko kukuthi umyinge we-CANH kunye ne-CANL) ukuyeka ukuhlala rhoqo. icandelo le-DC kwaye ibe yingxolo exhomekeke kwidatha.Kukho iindidi ezimbini zokungalingani okubangela le ngxolo: ingxolo ye-low-frequency ebangelwa ukungahambelani phakathi komgangatho ozinzileyo wemo yemowudi yemo elawulayo kunye ne-recessive states, enoluhlu olubanzi lweepateni zengxolo kwaye ibonakala njengoluhlu lwendlela efanayo. imigca yembonakalo ecandiweyo;kunye nengxolo ephezulu-frequency ebangelwa ngumahluko wexesha phakathi kwenguqu phakathi kwe-CANH elawulayo kunye ne-recessive ye-CANH kunye ne-CANL, equkethe i-pulses emfutshane kunye nokuphazamiseka okuveliswa yi-data edge jumps.Umzobo 1 ngezantsi ubonisa umzekelo wemveliso eqhelekileyo ye-CAN ye-transceiver ingxolo yemowudi eqhelekileyo.I-Black (i-channel 1) yi-CANH, i-purple (i-channel 2) yi-CANL kwaye eluhlaza ibonisa isixa se-CANH kunye ne-CANL, ixabiso elilingana nokuphindwe kabini i-voltage yemowudi eqhelekileyo kwindawo ethile ngexesha.
