Abstract: Aiming at the operation and maintenance management platform constructed by BIM technology in current railway operation and maintenance management, this article put forward the application scheme of daily operation and maintenance based on image recognition technology. The combination of image recognition technology and BIM technology was applied to the information system of operation and maintenance management. By comparing different recognition technologies, the article proposed a method of updating equipment status information by using YOLO V3, so as to improve the efficiency and quality of operation and maintenance management.
