Review and Prospect of EMUs Operation and Maintenance Technology Based on Digital Twins
摘要
Abstract
In response to the operation and maintenance requirements of China's high-speed Electric Multiple Units(EMUs),the application methods and implementation pathways of digital twin technology in EMU operation and maintenance are explored.A digital twin technology based EMU operation and maintenance framework is proposed,focusing on addressing key technical challenges including data fusion analysis,digital twin model construction,operation and maintenance decision optimization,and inspection-operation interaction.In the data fusion analysis aspect,precise identification of fault characteristics is achieved through multi-source heterogeneous data integration and deep mining.For digital twin modeling construction,a five-dimensional operational maintenance-oriented digital twin model is constructed,incorporating lightweight technology to ensure accuracy and real-time performance of the model.Regarding operation and maintenance decision optimization,methods such as feature vector extraction,fault prediction,and condition assessment are employed to establish a multi-objective optimization-based maintenance decision mechanism.In the inspection-operation interaction aspect,the application of virtual environment construction,visual enhancement,and immersive interaction technologies enhances the intelligence level of maintenance operations.The study demonstrates that implementing digital twin technology in EMUs operation and maintenance not only improves system safety and cost-effectiveness,but also facilitates the transformation from traditional experience-based maintenance models to intelligent and refined operational paradigms.Future related study will continue to address technical integration challenges to achieve comprehensive implementation of this technology in EMUs operation and maintenance practices.关键词
