结构健康监测（SHM）传感技术的普遍出现和工程中无处不在的数字化（“工业4.0”）对土木工程中的信息建模概念提出了越来越高的要求。虽然在建筑信息建模（BIM）中，传统的建筑信息（如几何形状，材料或成本）可以使用当前的建模标准进行精确描述，但有关SHM系统的信息（称为“监控相关信息”）无法在定义明确的正式基础上进行充分描述。在本文中，提出了一种基于BIM的方法来描述监控相关的信息，使用行业基础类（IFC），一个开放的BIM标准，促进BIM模型的互操作性，作为一个正式的基础。首先，讨论了用IFC模式描述监测相关信息的可能性和限制。然后，描述SHM系统所需的信息集成到一个语义模型作为一个技术无关的元模型。接下来，IFC模式被扩展以使SHM系统的基于BIM的描述符合IFC建模能力，这被称为“IFC监视器”模式。IFC Monitor方案通过IFC官方认证计划中使用的测试软件进行验证。为了验证，一个原型SHM系统正式描述使用IFC监视器模式。验证的目的是检查IFC Monitor模式是否能够精确描述与监控相关的信息。正如本文所示，原型SHM系统的描述符合IFC官方认证计划中规定的定义明确的IFC模型的要求。因此，IFC监控方案提出了在这项研究中的进步BIM为基础的描述SHM系统与结构系统被监测上定义明确，正式的基础上。
The pervasive emergence of sensing technologies for structural health monitoring (SHM) and the digitalization ubiquitous in engineering (“Industry 4.0”) pose increasing demands on information modeling concepts in civil engineering. While in building information modeling (BIM) conventional building information (such as geometry, material, or cost) can precisely be described using current modeling standards, information about SHM systems, referred to as “monitoring-related information”, cannot be fully described on a well-defined, formal basis. In this paper, a BIM-based approach towards describing monitoring-related information is proposed, using the Industry Foundation Classes (IFC), an open BIM standard facilitating the interoperability of BIM models, as a formal basis. First, possibilities and constraints of describing monitoring-related information with the IFC schema are discussed. Then, information necessary to describe SHM systems is integrated into a semantic model serving as a technology-independent metamodel. Next, the IFC schema is extended to enable BIM-based descriptions of SHM systems in compliance with IFC modeling capabilities, which is referred to as “IFC Monitor” schema. The IFC Monitor schema is verified with test software used in the official IFC certification program. For validation, a prototype SHM system is formally described using the IFC Monitor schema. The validation aims at checking if the IFC Monitor schema is capable of precisely describing monitoring-related information. As will be shown in this paper, the description of the prototype SHM system meets the requirements of a well-defined IFC model as specified in the official IFC certification program. As a result, the IFC Monitor schema proposed in this study advances BIM-based descriptions of SHM systems in association with structural systems being monitored on a well-defined, formal basis.
