Abstract: Aiming at the problem of how to manage the railway passenger station equipment more efficiently, comprehensively and from multiple angles, this paper established the big data operation and maintenance service platform for railway intelligent passenger station equipment, and introduced its functional architecture and equipment health evaluation system. The platform had the functions of real-time monitoring of equipment operation status, active feature identification, fault prediction, operation and maintenance trend deduction, multi-attribute health status evaluation, improved the health degree of passenger equipment and the overall intelligent level of intelligent passenger station equipment management, and provided new management ideas and technical means for intelligent passenger station equipment operation and maintenance management. It lays a foundation for the development of health assessment application of passenger station equipment in the next step.
