针对CAN总线的多主竞争模式通过解析法难以建模这一问题,运用CPN Tools工具构建了基于有色Petri网的CAN总线CSMA/CA竞争机制模型,模拟了CAN总线的静态结构和动态行为,对CAN总线性能进行了仿真与分析。仿真结果验证了所建CAN总线模型的合理性与正确性。
Multi-master competing mode for CAN bus is difficult to model by using analytic method. The model of CSMA / CA competing mechanism of CAN bus based on colored Petri nets is constructed by CPN Tools, and the static structure and dynamic behavior of CAN bus are simulated. CAN bus performance simulation and analysis. The simulation results verify the rationality and correctness of the CAN bus model built.
