Abstract: In response to the differences in single professional operation and maintenance systems for urban rail transit, this paper utilized the data interface of the rail transit data sharing platform to design and develop a multi-professional intelligent operation and maintenance system for urban rail transit. The paper was based on microservice backend architecture and micro frontend technology to implement comprehensive monitoring, analysis, and prediction of data on various professional equipment, operating status, and operation management aspects of urban rail transit. It provides technical support for improving the safety and reliability of urban rail transit and achieving intelligent management.
