Abstract:According to the safety of oil and real-time reliability management requirements, this paper puts forward the CAN Bus distributed control system scheme. It introduces the core data processing unit S3C2410 in the use of expansion devices CAN Controller realizing sending, receiving and filtering bus packet, including the working principle of CAN Controller SJA1000, the methods of the general CAN Bus access controlling, and the design of CAN Bus Driver Program. Experimental results show that the technology in this paper, based on ARM CAN driver design and message transceiving and filtering is universal.
