摘要:

TSN工控系统多业务流融合的特点使得建立精确的数学模型非常困难。为保证安全策略与系统实时运行的协调,提出一种服务于安全策略生成与优化的“物理层-数据层-孪生层-服务层”四层双闭环数字孪生框架。通过服务层的初步安全策略生成与孪生层的部署验证间迭代优化构成的内闭环,实现最优安全策略生成;通过物理层与孪生体间构成的外闭环,实现安全策略动态调整。将工业领域控制器和电机间的确定性通信过程作为实验对象,验证了框架的有效性。

Abstract:

The characteristic of multi-service flow integration in TSN industrial control systems makes it very difficult to establish an accurate mathematical model. In order to ensure the coordination between the security policy and the real-time operation of the system, a four-layer double-closed-loop digital twin framework of "physical layer-data layer-twin layer-service layer" serving the generation and optimization of security policies is proposed. The optimal security policy generation is achieved through the internal closed loop composed of iterative optimization between the initial security policy generation at the service layer and the deployment verification at the twin layer. The deterministic communication process between the controller and the motor in the industrial field is taken as the experimental object to verify the effectiveness of the framework.

Key words: digital twin framework, TSN industrial control system, security policy decision-making, adaptive optimization, modeling and simulation
