Problems solved by technology

[0005] The operation and maintenance of traditional complex products is separated from the manufacturing link. After the manufacturer delivers the product to the user, the task of the manufacturer is completed. The operation and maintenance personnel rarely consider the manufacturing information of the manufacturer during the product operation and maintenance process, which leads to This prevents O&M and manufacturing information from being communicated in a timely manner, forming an information island

Embodiment 1

[0057] Such as figure 1 As shown, the overall model of complex product operation and maintenance and manufacturing integration based on digital twins, including operation and maintenance system module, virtual maintenance unit module, maintenance center module, manufacturing plant module and data platform module, the manufacturing plant module and maintenance center module constitute The physical space of the twin system, the virtual maintenance unit module constitutes the virtual space of the twin system, the operation and maintenance system module, the virtual maintenance unit module, the manufacturing plant module and the maintenance center module respectively transmit the service data, simulation data, manufacturing data and maintenance data To the data platform module, and receive the feedback of the data platform module; the data platform module will collect the data information, after the data fusion processing unit performs data fusion processing, it will interact with ...

Embodiment 2

[0068] Such as figure 2 As shown, a digital twin-based operation mode of complex product operation and maintenance and manufacturing integration overall model, including:

[0069] 1) When an abnormality occurs during the operation of a complex product, the operation and maintenance personnel need to analyze the cause of the abnormality in the operation and maintenance system, obtain the repair information data of the parts that need to be repaired after fault diagnosis, and input the repair information data of the parts into the data platform module;

[0070] 2) The data platform module formulates a preliminary maintenance plan based on historical maintenance data, knowledge base and instance database, simulates the preliminary maintenance plan in the virtual space, and calls the knowledge base in the data platform to carry out the preliminary maintenance plan Judgment, if it is not the optimal maintenance plan, continue to simulate in the virtual space, and correct the main...

Abstract

The invention provides a complex product operation, maintenance and manufacturing integrated general model based on digital twinning. The complex product operation, maintenance and manufacturing integrated general model comprises an operation and maintenance system module, a virtual maintenance unit module, a maintenance center module, a manufacturing plant module and a data platform module. The invention also provides a digital twinning-based operation, maintenance and manufacturing integrated process operation mode, modeling simulation, data fusion processing and other solutions, and discusses digital twinning-based key technologies such as intelligent diagnosis, fault prediction, data comprehensive perception, knowledge base/instance library construction and the like. Complex product operation and maintenance and manufacturing information are deeply fused, operation and maintenance and manufacturing data are interactively fed back, virtual and real combination of complex product operation and maintenance and manufacturing is realized through digital twinning, and more real-time, efficient and intelligent integrated services are provided. According to the operation mode of the complex product operation, maintenance and manufacturing model based on digital twinning, deep integration of the complex product operation, maintenance and manufacturing process is achieved, and the information island phenomenon generated in the operation, maintenance and manufacturing links is eliminated.

Description
