描述
CAN總線通過CAN控制器接口芯片82C250的兩個輸出端CANH和CANL與物理總線相連，而CANH端的狀態(tài)只能是高電平或懸浮狀態(tài)，CANL端只能是低電平或懸浮狀態(tài)。這就保證不會出現(xiàn)像在RS-485網(wǎng)絡(luò)中，當系統(tǒng)有錯誤，出現(xiàn)多節(jié)點同時向總線發(fā)送數(shù)據(jù)時，導(dǎo)致總線呈現(xiàn)短路，從而損壞某些節(jié)點的現(xiàn)象。而且CAN節(jié)點在錯誤嚴重的情況下具有自動關(guān)閉輸出功能，以使總線上其他節(jié)點的操作不受影響，從而保證不會出現(xiàn)象在網(wǎng)絡(luò)中，因個別節(jié)點出現(xiàn)問題，使得總線處于“死鎖”狀態(tài)。CAN具有完善的通信協(xié)議，可由CAN控制器芯片及其接口芯片來實現(xiàn)，從而大大降低了系統(tǒng)的開發(fā)難度，縮短了開發(fā)周期，這些是只僅僅有電氣協(xié)議的RS-485所無法比擬的。
