摘要
针对油库管理的实时性和可靠性等要求,在论述CAN总线驱动程序的基础上提出了基于CAN总线的分布式控制系统方案。主要介绍了在核心数据处理单元S3C2410上利用扩展设备CAN控制器实现总线报文的过滤与收发。其中包括CAN控制器SJA1000的工作原理,以及CAN总线访问控制的一般方法,CAN总线驱动程序的设计。实验证明,所论述的基于ARM CAN的驱动程序设计和报文收发过滤技术具有普遍意义。
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.
