摘　　要：设计了一种满足高可靠性要求的CAN网络节点系统.该CAN节点由带CAN总线控制器的微处理器、CAN总线驱动电路、扩展接口电路组成,主控单元电路全部集成在单芯片中;在完成硬件电路设计的同时,还引入了实时多任务操作系统RTX51Tiny平台,并基于该系统开发CAN节点功能应用.整个完整电路以及软件代码都在FPGA平台上完成了系统仿真以及功能验证,并最终通过节点功能验证板完成CAN节点实际系统测试.实际运行结果证明该节点系统硬件功能正常,软件系统有效可靠.The highly reliability CAN-bus network node composed of microprocessor, CAN-bus driver and expand interfaces is designed. CPU and CAN controllers are integrated into a single chip. This paper not only propose the circuit design of the CAN-bus network node system, and also develop the application software on RTX51 Tiny, a real-time operating system （RTOS）, running in this node system. Finally, Verilog and C codes are verified by FPGA＇s DE tools, and tested in the node, a FPGA board. Actual operation results show that the node system function is trustworthy, and the software system is reliable.
