The urban emergency management system is very necessary for the construction of a modern city, and it is also an urgent issue faced by the city government managers. Based on the basic theory of urban emergency management, a comprehensive analysis of the successful experience and shortcomings of urban construction and use of emergency management systems at home and abroad is carried out. The purpose, scope and related factors of the urban emergency management system are analyzed in this paper. The working model is detailed. On this basis, this article proposes a framework for urban emergency management system, which is based on a three-dimensional cube structure, and builds a corresponding management system based on this structure. This will be a very important practical application to provide a network of real-time monitoring and operating data systems on the Internet. Provide efficient and practical multi-sensor data fusion algorithm. In order to provide a convenient set of middleware architecture and components, this is the link that connects and manages the sensing layer and advanced application systems, allowing users to apply the data collected by the sensing layer to business processes.
