随着物联网和工业4.0概念的出现，土木工程中的网络物理系统对结构健康监测（SHM）和控制应用的影响越来越大。在正式的基础上设计、优化和记录信息物理系统需要平台无关和技术无关的元模型。这项研究，强调在信息物理系统中的通信，提出了一个描述信息物理系统的元模型。首先，在土木工程计算中常用的元建模概念进行审查和描述通信相关的信息的可能性和局限性进行了讨论。接下来，解释了应用于SHM和控制的分布式信息物理系统的通信相关属性和行为，并指定了与通信相关的系统组件。然后，元模型，以正式描述信息物理系统的建议和映射到工业基础类（IFC），一个开放的国际标准，建筑信息建模（BIM）。最后，IFC为基础的方法进行了验证，使用软件的官方IFC认证计划，它是通过基于BIM的示例建模的原型网络物理系统，这是在实验室中物理实现的。因此，描述了应用于SHM和控制的信息物理系统，并在IFC的正式基础上存储、记录和交换信息，促进了信息物理系统的设计、优化和记录。
With the advent of the Internet of Things and Industry 4.0 concepts, cyber-physical systems in civil engineering experience an increasing impact on structural health monitoring (SHM) and control applications. Designing, optimizing, and documenting cyber-physical system on a formal basis require platform-independent and technology-independent metamodels. This study, with emphasis on communication in cyber-physical systems, presents a metamodel for describing cyber-physical systems. First, metamodeling concepts commonly used in computing in civil engineering are reviewed and possibilities and limitations of describing communication-related information are discussed. Next, communication-related properties and behavior of distributed cyber-physical systems applied for SHM and control are explained, and system components relevant to communication are specified. Then, the metamodel to formally describe cyber-physical systems is proposed and mapped into the Industry Foundation Classes (IFC), an open international standard for building information modeling (BIM). Finally, the IFC-based approach is verified using software of the official IFC certification program, and it is validated by BIM-based example modeling of a prototype cyber-physical system, which is physically implemented in the laboratory. As a result, cyber-physical systems applied for SHM and control are described and the information is stored, documented, and exchanged on the formal basis of IFC, facilitating design, optimization, and documentation of cyber-physical systems.
