应用51单片机为控制核心结合其他的器件设计了一种能连接于CAN总线上的智能节点。通过单片机控制CAN总线控制器SJA1000，并进一步通过CAN总线收发器PCA82C250，实现该智能节点与CAN总线的通信。此外通过对MCS-51单片机的I／O进行相应的扩展，使该智能节点具有了8输入和8输出的控制端口。最终完成该智能节点并通过实际测试，验证了其实用性。

The thesis introduces a design of a kind of an intelligent node, which is used to communicate with CAN bus. Single- chip microcomputer MCS-51 is applied as a central controller, of which other devices operate under control. Applying the Single-chip microcomputer to control CAN bus controller SJA1000 realizes the communication with CAN bus, through the CAN bus transceiver PCA82C250.Through I/O extension of MCS-51 MCU, the intelligent node has the control port of eight inputs and eight outputs. At last the practicability of the intelligent node has been verified by the practical tests.
