Knowledge service method for digital twin model of complex equipment

The invention provides a knowledge service method for a complex equipment digital twin model, and belongs to the technical field of complex equipment knowledge engineering. The invention discloses a knowledge service mechanism method for construction of a knowledge classification ontology model of complex equipment, knowledge mapping based on a meta-structure tree of the complex equipment and dynamic calling of a twinborn model according to a knowledge application requirement in digital twinborn of the complex equipment and a loose coupling and extensible reference principle of the knowledge and the digital twinborn model. A knowledge service algorithm oriented to dynamic calling of a digital twin model is designed and realized, dynamic requests of real-time physical information data of equipment nodes for knowledge are realized, and support is provided for equipment anomaly prediction, fault diagnosis, performance prediction and the like. 本发明提出一种面向复杂装备数字孪生模型的知识服务方法，属于复杂装备知识工程技术领域。该方法针对复杂装备数字孪生中的知识应用需求，按照知识与数
