摘要
文章从分析CAN 2.0B总线协议入手,通过计算CAN总线的总线负载率,得出单个CAN总线传输报文帧的上限值。针对单个CAN总线不能满足通信需求的问题,提出了将网络节点划分在两个子网中的优化方法,最后,介绍了将本方法应用于优化某模拟CAN总线节点的例子。
Based on analyzing CAN 2.0B bus protocol, the upper limit of single CAN bus transmitting packet frames in a single CAN bus is obtained by calculating busload rate of the CAN bus. In view of the problem that the single CAN bus cannot meet the communication requirement, the optimization method of arranging the network node in two subnets is presented. Finally, an example of using this method to optimize an analogue CAN bus node is given.
