Abstract: The information islands were increased in the different transport workshop of railway passenger station. Due to this, based on the station service, combining with the Internet technology and security closed-loop management theory, it was designed a set of key issues reminder system for railway passenger station based on closed loop management, which was focused on key issues as the center. The system has the characteristics of strong planning, high safety standard, notice period advance, etc. The development of trial showed that the system could achieve the expected effect of reducing information islands of transport workshops. It laid the foundation of the evolution from “digital station” to “intelligent station” for the railway passenger service.
