Kedu ihe bụ transceiver CAN?
Onye transceiver CAN bụ mgbawa ntụgharị 232- ma ọ bụ 485 dị ka nke ọrụ ya bụ ịtụgharị akara TTL nke onye na-ahụ maka CAN ka ọ bụrụ akara dị iche nke ụgbọ ala CAN.
Kedu ihe TTL onye njikwa nwere ike igosi?
A na-ejikọta ndị na-ahụ maka CAN nke oge a na MCU na nnyefe ha na-anata akara TTL bụ akara MCU (nke dị elu ma ọ bụ dị ala).
N'oge gara aga enwere ndị na-ahụ maka CAN dị iche iche na oghere netwọk CAN ga-enwe ibe atọ: MCU mgbawa, CAN njikwa, na CAN transceiver.Ugbu a ọ bụ nke mbụ abụọ na-ejikọta ọnụ (lee foto na mmalite nke isiokwu).
Njirimara ntinye
Maka ndị transceivers CAN dịpụrụ adịpụ, ntinye na-ezo aka karịsịa na njirimara ntinye dị n'akụkụ njikwa CAN nke njikọ ahụ, gụnyere ntinye ike na ntinye mgbaàmà.
Dabere na voltaji CAN interface nke onye njikwa, enwere ike ịhọrọ modul CAN nwere ikike 3.3V ma ọ bụ 5V.Usoro ntinye nkịtị nke modul CAN dịpụrụ adịpụ bụ VCC ± 5%, tumadi na-atụle na enwere ike idobe ọkwa ụgbọ ala CAN n'ime ụdị uru a na-ahụkarị ma na-emekwa ka mgbawa CAN nke abụọ rụọ ọrụ gburugburu voltaji ọkọnọ ọnụ.
Maka ibe ibe CAN transceiver dị iche, pin VIO nke mgbawa kwesịrị ijikọ ya na voltaji ntụaka dị ka ọkwa akara TXD iji kwekọọ ọkwa mgbama, ma ọ bụ ọ bụrụ na enweghị pin VIO, a ga-edobe ọkwa mgbaama n'usoro na VCC. .Mgbe ị na-eji usoro CTM dịpụrụ adịpụ transceivers, ọ dị mkpa ijikọ ọkwa mgbaàmà nke TXD yana voltaji ọkọnọ, ntụgharị 3.3V ọkọlọtọ CAN njikwa interface ma ọ bụ 5V ọkọlọtọ CAN interface interface.
Njirimara nnyefe
Njirimara nnyefe nke transceiver CAN dabere na paramita atọ: nyefee igbu oge, nata igbu oge, na igbu oge okirikiri.
Mgbe ị na-ahọrọ transceiver CAN, anyị na-eche na ntakịrị ihe nkwụsịtụ igbu oge ka mma, mana kedu uru nke obere nnyefe na-eweta na ihe ndị na-egbochi nkwụsị nnyefe na netwọk CAN?
Na CAN protocol, ọnụ ụzọ izipu na-eziga data site na TXD ebe RDX na-enyocha steeti ụgbọ ala.Ọ bụrụ na ihe nlebanya RDX adabaghị n'obere nnyefe, ọnụ na-achọpụta ntakịrị mperi.Ọ bụrụ na ihe a na-enyocha n'ọhịa ikpe ekwekọghị n'ezie nnyefe, ọnụ na-akwụsị na-ekesa, ya bụ e nwere otutu ọnụ na ụgbọ ala na-eziga data n'otu oge na ọnụ na-adịghị enye data mbufe mkpa.
N'otu aka ahụ, na ma nlele data yana ntakịrị nzaghachi ACK, achọrọ RDX iji nweta ọkwa data nke ụgbọ ala ozugbo.Dịka ọmụmaatụ, na nkwurịta okwu netwọk nkịtị, ewezuga ihe ndị na-adịghị mma, iji nweta nzaghachi ACK nke ọma, ọ dị mkpa iji hụ na a na-ebufe ACK bit na ndekọ RDX nke onye njikwa n'ime oge ụfọdụ, ma ọ bụghị ya, ọnụ na-ezipụ ga- chọpụta njehie azịza.Tọọ ọnọdụ nlele na 70% na 1Mbps.Mgbe ahụ, onye na-ahụ maka ya ga-enyocha ihe ACK bit na 70% nke oge site na mmalite nke oge ACK bit, ya bụ, nkwụsịtụ okirikiri nke netwọk CAN niile ga-abụ ihe na-erughị 700ns, site na oge TXD na-eziga, ruo mgbe ACK. a na-anata bit na RDX.
N'ime netwọk CAN dịpụrụ adịpụ, a na-ekpebi oke a site na igbu oge dịpụrụ adịpụ, igbu oge ọkwọ ụgbọ ala CAN, yana ogologo eriri USB.Ya mere, obere oge igbu oge na-enyere aka ịlele bits ACK na ntụkwasị obi yana ịbawanye ogologo ụgbọ ala.Ọgụgụ 2 na-egosi nzaghachi ACK nke ọnụ abụọ na-ekwurịta okwu site na iji transceiver CTM1051KAT.Oge igbu oge dị na transceiver bụ ihe dịka 120ns.
