摘要
CAN总线已经形成国际标准(ISO11898),并已成为工业数据通信的主流技术之一。本文介绍了一种应对恶劣电磁环境的CAN接口电路。首先对接口电路总体框图进行介绍,然后着重对隔离部分、CAN总线收发器部分及外围电路元器件选择进行了详细说明,最后,对设计的实验测试情况进行了描述。
CAN bus has been the international standard （ISO 11898） and become one of the mainstream technologies of industrial data communication. A CAN interface circuit in harsh electromagnetic environment is introduced in this paper. Firstly this paper introduces the overall block diagram of the interface circuit, and then focuses on the isolation part, CAN transceiver part and selection of peripheral circuit components. Finally the designed experiments are described.
