摘　　要：依据CAN总线和RS-232的特点,给出了RS-232到CAN总线的智能转换卡的设计。以集成CAN控制器的微处理器AT90CAN128为核心,设计了转换卡的硬件电路。通过对微处理器AT90CAN128合理设置,结合软件设计进行数据的收发,实现RS-232到CAN总线的转换。According to the feature of CAN bus and RS -232, the design of RS-232-CAN interface converter was presented. On basis of microcontroller AT90CAN128 with CAN controller inside, the hardware of the converter was given. By setting up AT90CAN128 properly, and combining with software design, the receiving and sending of data is realized, and it meets the need of convert between RS- 232 and CAN bus.
