Outline
Urban rail transit dispatching and command work involve complex system engineering, and the emergency dispatching and command system, as the top priority of urban rail transit dispatching and command work, directly affects the level of enterprise operation services and train operation safety. The emergency dispatch and command system is a paramount component within this framework. Using the Tianjin Metro emergency dispatch as a case study, this research first outlines the foundational modes of emergency dispatch and command used in domestic urban rail transit. It also integrates current trends in information integration and intelligent operations within urban rail transit. The study then delineates the objectives and functional requirements specific to the Tianjin Metro emergency dispatch and command platform. It proposes an architecture comprising several key layers: infrastructure, data resources, application support, application software, information display, regulatory standards, and security systems. This structured approach ensures comprehensive coverage of operational needs and regulatory compliance. Furthermore, leveraging technologies such as cloud computing and big data, we explored the technical scheme and implementation plan of the Tianjin Metro emergency dispatch command platform for the integration demand and intelligent trend. The research results can provide decision support for the safe and orderly operation and dispatch of subways under networked conditions.
