摘要
为提高光纤CAN网络的可靠性 ,设计了高可靠性带有保护环的光纤双环CAN网络以及相应的fiber CAN总线接口电路。着重设计了基于看门狗的光纤双环自动保护倒换电路。通过 5个节点的fiber CAN总线组网 。
In order to enhance the reliability of optical fiber CAN network, a reliable dual ring optical fiber CAN network with protective ring and relevant fiber-CAN bus interface circuit are designed. The automatic protective switchover circuit based on watchdog for dual ring is designed emphatically. Through 5-node networking of fiber-CAN bus, the availability of optical fiber dual ring CAN bus network and correctness of automatic protective inverted switchover circuit are verified.
