Digital twins serve as a connection between the physical and digital worlds, enabling the creation of a comprehensive digital representation of the entire lifecycle of physical materials, including material selection, structural design, processing, manufacturing, and operation and maintenance management. This paper examines the technical framework and implementation process of equipment digital twin modeling and analyzes the standardization requirements for key technical aspects such as basic rules, information acquisition, model accuracy, timeliness, versatility, as well as model verification and management. Through a case study of a workshop manipulator, the research explores the modeling theory and technology of equipment digital twins, providing a theoretical basis, standard support, and technical references for the application of digital twin technology throughout the equipment lifecycle. Finally, the future development trends and challenges of equipment digital twins are discussed.
Aiming at the problems of extensive data semantic differences and complex data analysis and processing caused by data fragmentation, semi-structure, and information heterogeneity in the information interaction of node devices under the edge computing framework, this paper proposes an information model to load the state data of the node and develops a corresponding parser for the information model, which reduces the heterogeneity of node data and ensures that the data can be uniformly connected to the edge computing platform. Through the device monitoring platform, the running status of various devices can be viewed in real-time, which proves the feasibility and effectiveness of the proposed information model and parser.
This paper proposes a time-sensitive network performance test program based on a real-time edge computing platform. It uses a real-time data engine with a time-series database as the core to realize the collection and status monitoring of the real-time communication flow of the time-sensitive network. The clock synchronization is carried out by building a specific test experimental platform and end-to-end latency performance testing, and the results show that TSN network can ensure the delay of the time sensitive flow in the transmission process and the real-time arrival of the message in the complex network environment.
