Abstract

The embodiment of the invention provides a digital twinning method and system based on a graph database. The method comprises the steps of obtaining entity information description data of each physical entity in a physical space; according to the entity information description data of each physical entity, identifying a domain model of the model database through a domain model identification algorithm to obtain a target domain model of each physical entity, and constructing a digital virtual body of the corresponding physical entity according to each target domain model; and storing the modelrelationship between the target domain models and the virtual body relationship between the digital virtual bodies into a graph database so as to construct the digital twinning based on the graph database. According to the embodiment of the invention, the domain model of the physical entity can be quickly identified, so that the data twinning based on the graph database is established, the construction efficiency and retrieval application efficiency of the domain model are improved, and the construction process of the digital twinning is simplified.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a digital twin method and system based on a graph database. Background technique [0002] Digital twin (Digital Twin) is to make full use of information such as physical models, sensor data and historical data, integrate multi-disciplinary, multi-physical quantities, multi-scale and multi-probability simulation processes, and complete the mapping in the virtual space to reflect the corresponding physical equipment whole life cycle process. [0003] At present, as a new concept, digital twin is widely used in the field of industrial Internet to achieve comprehensive insight into industrial objects and industrial processes. However, the existing digital twin technology has low efficiency in constructing digital virtual bodies, the construction process of the digital twin system is complicated, and the advantages brought by the application in product design, manufacturing a...
