CAN总线控制系统的设计

Design of the CAN bus control system

根据CAN总线的特点,设计了分布式智能控制系统(由上位机、CAN总线和下位机组成),并以总线控制器SJA1000为核心,实现了智能控制节点(下位机)的设计.给出了控制系统的系统结构、智能控制节点的硬件结构、CAN总线的通讯原理及软件的实现方法.应用表明:该系统数据传输可靠,控制动作灵活,有较强的通用性.

Introducing the CAN bus characteristic,by on position machine,the CAN bus and the lower position machine has been composed by the distributional intelligence control system.Taking bus control unit SJA1000 as the core,we have realized the intelligence control pitch point which is the lower position machine design.The control system structure,the system composition,the intelligence pitch point hardware architecture have been produced,and the CAN bus communication principle and the software realization method have been achieved.
