Abstract: The application status and problems of the railway engineering management platform built in cloud computing are analyzed. Based on the concept of edge computing, the architecture design of the railway intelligent construction site production management system is proposed and its applications in the three scenario of concrete mixing station production automation, video surveillance for railway construction site, surrounding rock deformation detection in tunnel engineering are explored in hope of seeking better solutions for production automation, real-time monitoring, data optimization, intelligent analysis and other applications of intelligent railway construction site.
