摘要
基于控制系统智能化水平日益增长的背景,快速自动识别出CAN总线网络拓扑关系的需求日益突出,采用在CAN总线传统网络架构中增加中间层的措施,结合CAN总线网络链路动态分离的机制,设计了详细的切换电路,介绍了电路的工作原理及整个系统的工作原理,明确了总线数据的处理流程、方法,实现了CAN总线网络拓扑关系的快速自动识别,为后续相关技术的应用奠定了基础。
Witli the development of tlie intelligent of control-system,fast-automatic recognition of tlie CAN networlc topology has became an u r-gent technology. Based on the new middleware and dynamic separation of CAN, a switching circuit has been designed. The principle of the system,esjDecially the circuit system was introduced,the data processing was elaborated,and the goal of fast-autnetwork topology was achieved,which lays the foundation of follow-up related technologies.
