Abstract: The design of railway emergency command system based on distributed cloud architecture was to solve the problem of intelligence and integration deficiencies of railway station emergency command business. Through the deployment of emergency data and various emergency services in the emergency cloud platform of each station, it could implemented the horizontal integration monitoring of station equipment, facilities, system software, personnel,environment and other resources, achieved vertical integration management of contingency plan, organization,response, disposal, recovery and evaluation process. The trial running results show that the technical plan of the intelligent emergency command system for railway passenger station based on distributed cloud architecture meets the development trend of the railway emergency command.
