Life Cycle Management System of Metro Electromechanical Equipment Based on Internet of Things Technology

There are many kinds of metro operation equipment,among which electromechanical equipment occupies an important position in equipment management.With the development of Internet-of-things technology,multidomain,multimodule,multidirectional information interconnection and sharing are realized.Facing the data fusion of various dimensions,establishing a reasonable analysis and management platform is the future development trend of smart city metros.Based on the equipment management system of Zhengzhou Metro operation,this study expands the direction of panoramic information support platforms,status monitoring,online early warning,intelligent diagnosis,status evaluation,risk prediction,maintenance decisions,and performance evaluation.A framework of a large data management system for metro electromechanical equipment was built,and a machine-learning algorithm was used for effective data mining through the existing data structure.At the same time,the algorithm model was analyzed in three directions—life cycle cost analysis,operation and maintenance decision making,and risk quantification evaluation—to obtain a potential law for metro electromechanical equipment and provide more valuable information for decision makers.
