Abstract: Under the guidance fo the development strategy of "rail transit+new urbanization", major cities in China are rapidly promoting networked operation of rail transits. Based on supported by cloud computing and big data technology, and focusing on the business process of networked operation and dispatch command, this article establishes a cross platform intelligent dispatch system for the network operation command center of rail transits based on a hybrid big data architecture and standardized interfaces (referred to as the intelligent dispatch system), and preliminarily completes the design of main application functions such as network operation and command, network emergency command, network passenger service, and network auxiliary decision-making; By achieving information sharing and business linkage between rail transit network level operation scheduling command and emergency management, we support efficient collaboration between daily operation scheduling command and emergency response business of rail transit network, enhance the ability of rail transit network coordination operation decision-making and evaluation analysis, help guide the standardized construction of rail transit industry network command center system, and promote the intelligent development of rail transit network operation management.
