The application provides a multi-layer signal interaction propagation method, device and equipment in a multi-layer system, and relates to the technical field of social network analysis and information propagation. The method comprises the following steps: acquiring basic information of a multi-layer complex system and information to be propagated; constructing a multi-layer hypergraph structure according to the basic information of the multi-layer complex system; determining an associated hyperedge set of each node in a public node set; performing an iterative screening operation from the public node set according to an initial coupling degree to obtain a seed node set; performing intra-layer propagation of the information to be propagated in a current hypergraph layer according to an initial propagation state and a preset intra-layer propagation rule; when it is detected that the information to be propagated is propagated in the current hypergraph layer, the information to be propagated is transferred to a next hypergraph layer for intra-layer propagation according to a preset cross-layer propagation rule until there is no newly added active node. The method of the application realizes efficient and accurate multi-layer influence propagation modeling and seed optimization, and improves the authenticity and timing accuracy of signal propagation simulation.

The application discloses an intelligent early warning communication system for public safety events based on AI semantic analysis, relates to the technical field of public safety event early warning, and comprises four core modules.A public event safety evaluation module collects text, audio and video stream data of a target region, analyzes an event threat comprehensive evaluation value to determine whether a public safety event occurs, a public event safety authenticity verification module acquires group behavior dynamic trend indexes to verify the authenticity of an event when it is determined that an event occurs, an event safety risk level analysis module analyzes the safety risk level of an event and matches an early warning communication scheme according to the threat comprehensive evaluation value when the event is true, and an event diffusion risk level analysis module derives a surrounding area cooperative early warning scheme according to the safety risk level of an event, and constructs an intelligent public safety early warning and prevention and control system.
