Abstract

To address the high costs and low efficiency faced by electromechanical equipment manufacturers when providing maintenance

repair

overhaul

and operation (MRO) services to remote clients

a digital twin-driven remote operation and maintenance method for electromechanical equipment is proposed. First

an analysis is conducted from both the remote operation and maintenance service server and client perspectives

leading to the construction of a mathematical model for digital twin remote MRO services. Next

cloud servers are utilized to achieve virtual-physical synchronization between local clients and remote servers. A twin electromechanical model of the equipment is established from the server’s perspective

and the issue of heterogeneous data integration in remote maintenance is addressed. The implementation process of remote maintenance services and intelligent fault diagnosis is investigated. Finally

a three-axis computer numerical control machining device is selected as the subject for deploying a three-layer architecture of digital twin remote maintenance services

facilitating synchronized monitoring of the operating process and spindle motor fault diagnosis. The results indicate that the twin model at the remote service end enables real-time synchronized monitoring of the client device

allowing for remote data collection

analysis

and intelligent fault diagnosis

thereby validating the effectiveness of the proposed model and method. This research provides a reference for digital twin-driven remote maintenance services.
