Abstract：
Aiming at the problems of data integration and information sharing in the calibration workshop of smoke alarm, combining OPC Unified Architecture (OPC UA) and digital twin technology, the OPC UA based digital twin smoke alarm calibration workshop information network framework is proposed. Using OPC UA information modeling technology, a digital workshop information model for smoke alarm calibration was constructed, and the static attribute set, process attribute set, and functional component set of the workshop were defined in detail. Taking the smoke box as an example, the information model construction was instantiated, and data collection and transmission were carried out with the digital twin model of the smoke box, achieving the implementation mapping between the twin model and physical entities. The results show that based on the proposed OPC UA information model, the interconnection and intercommunication of data at all levels of the digital twin smoke alarm calibration workshop can be achieved, and the workshop can be visualized, digitized, and flexible.
摘要：
针对烟雾报警器校准车间的数据集成和信息共享问题,结合OPC统一架构（OPCUA）和数字孪生技术，提出了基于OPCUA的数字孪生烟雾报警器校准车间信息网络框架。采用OPCUA信息建模技术,建立了烟雾报警器校准的数字化车间信息模型，和静态属性集，进程属性集，详细定义了车间的功能组件集。以烟盒为例,实例化了信息模型构建，并利用烟箱的数字孪生模型进行了数据采集和传输，实现孪生模型和物理实体之间的实现映射。结果表明,基于所提出的OPCUA信息模型,可以实现数字双烟报警器校准车间各级数据的互联和互通，车间可以可视化，数字化,灵活。
