Problems solved by technology

In addition, the aforesaid invention uses the relationship matrix and the relationship adjacency matrix to construct the topological view of parts, processes and equipment as a two-dimensional plane relationship view, which does not have the ability to express three-dimensional models, and cannot faithfully reflect the real-time status of a single entity in the physical world. The running status has limitations in real-time monitoring and display effects
[0006] 2. The adopted digital twin monitoring modeling system runs separately from the factory's information system. When the digital twin monitoring modeling system is integrated into the WEB-based information system, there is interactive data between systems, and the created digital twin monitoring model is transferred to the WEB. Page integration and other development work, when industrial enterprises implement digital twin monitoring systems, the efficiency of data interaction with existing information systems is low, and the integration workload between systems is large
