Rapid Modeling And Simulation Of UAV Swarm Search In Emergency Logistics

With the continuous development of UAV equipment technology,UAV swarms are increasingly applied to the field of emergency search.However,since the traditional modeling approach cannot adapt well to the rapid changes of search tasks in emergency scenarios,the realization of data-driven rapid modeling and simulation of UAV swarms has become the focus of this paper.First,the UAV swarm search problem is studied,and four more common search methods,namely traditional scan search,diagonal search,sector search and extended square search,are summarized to achieve fast modeling and simulation,and Anylogic is also selected as the simulation platform.Next,the general framework of data-driven modeling and simulation is analyzed,and a modular fast modeling method is summarized to divide the modeling process into establishing a physical model,a logical model,and a data model.The physical model includes the physical composition of the UAV and gimbal camera,the target and the search site,the logical model includes the motion logic of the four search methods,the rotation and search of the gimbal camera,the setting of the initial position and the The data model includes the motion parameters and structural parameters of the entity.Then the data model is created in the access database,the logical model and the solid structure model are created in Anylogic,and the model is instantiated by accessing the data in the database through database connection technology to achieve fast data-driven modeling and simulation.Finally,the experiments are conducted by assigning values to the data model to verify that the model can achieve fast modeling and simulation under different search strategies,different site areas,and different numbers of UAVs,and the simulation time used to complete each group of experiments is counted to prove the effectiveness of the model for fast modeling and simulation in terms of timeliness and functionality.The modularity of the logic model for fast modeling and simulation is also analyzed,and these modular logic models provide a basis for future model extensions.
