Architecture and Key Technologies of Digital-twin-driven Intelligent Operation & Maintenance Services for Complex Product

Abstract

Focused on the problem of virtual-real interaction and collaboration and intelligent management for complex product, the architecture of digital-twin-driven intelligent operation and maintenance services for complex product (DT-IOMS-CP) is proposed. Then the implementation logic and key technologies of DT-IOMS-CP are elaborated, which includes formalized modelling and cooperative interaction of physical-virtual spaces, operation and maintenance (O&M) knowledge acquisition of complex product based on multi-source data, process tracking and monitoring based on virtual-real interaction, and service-oriented real-time diagnosis and active maintenance, etc. Through the implementation of above-mentioned architecture and key technologies, a management and collaboration mechanism of complex product O&M characterized by virtual-real interaction and fusion, dynamic updating of O&M knowledge and active performing of O&M services is established. Finally, the CNC machine tool is used to verify the effectiveness and feasibility of the proposed architecture and methods in the aspects of architecture application mode and identification method of O&M key performance indicator. The proposed framework and key technologies could provide a reference solution for intelligent, collaborative and service-oriented management and application of complex product.
