Exploration of digital maintenance for highway electromechanical equipment based on digital twin

To address the issues of relying on manual maintenance and insufficient digitization in the management of highway electromechanical equipment. This paper introduces the design and development process of the highway electromechanical Digital Twin platform from the perspective of full-lifecycle asset management and digital maintenance. The platform's functions focus on equipment asset management, providing a digital solution for real-time monitoring, fault alarm and diagnosis. The platform collects electromechanical equipment data and highway elements to construct a digital twin system integrated with map services, facilitating high-performance 3D visualization for equipment management. The system has designed a series of core modules to enhance platform performance, including scenario rapid construction, equipment layout schemes simulation, and equipment spatial correlation display. Through the application of a platform at the test site, the platform demonstrated the advantages of digital maintenance, boosting maintenance efficiency, and enhancing user interaction experience. The research has promoted the development of highway digitization.
