    • Availability evaluation of controller area networks under the influence of intermittent connection faults

    • 间歇性连接故障影响下的控制器局域网可用性评估
    • “工业领域广泛使用的现场总线之一——控制器局域网（CAN）的安全性及可靠性研究取得了新进展。针对CAN网络中频繁出现的间歇性连接（IC）故障，专家提出了一种实时定量评估CAN可用性的新方法。该方法基于网络状态转换模型，首先构建了IC故障与网络错误响应之间的因果关系，并据此估计了IC故障到达率。接着，分析了考虑IC故障的网络状态，并运用确定性与随机性Petri网（DSPN）模型描述了状态之间的转换关系。通过确定DSPN模型的参数，并基于该模型的概率分布和标记物理意义计算了系统可用性。实验验证表明，该方法估计结果与实际值吻合良好。这一研究成果为CAN网络实时健康监测提供了有效手段，为工业自动化领域的安全性和可靠性保障开辟了新的方向。”
