摘　　要：分析了控制器局域网络(CAN)总线调度的特点及其与传统单调速率调度算法(RM)的区别,讨论了将CAN总线应用于实时性要求严格的实践存在的问题,使用Petri网络方法对CAN总线建模.仿真实验数据表明,该模型可以优化CAN总线负荷,提高CAN总线的实时性能.The paper analyses the characteristics of CAN scheduling, which is different from traditional RM algorithm to some extent. And it discusses problems related to use of the CAN BUS in time-critical process control applications. A system model based on Petri nets is presented and evaluated. Results with evaluations proved that the model could analyze and optimize the real-time performance of CAN which is suitable for several time-critical application.
