As global warming causes the disasters greatly impact the natural and human systems,the use of scientific means to monitor environmental and climate change is essential to reduce the risk of disasters to human society.However,current Io T systems have inherent defects such as high energy consumption and strong dependence on reliable communication.At the same time,the chaotic complexity of the environment also brings unfavorable conditions to the connection of Internet of Things and sensors.For example,the lack of power supply,the deep fading nature of wireless communication,make the Internet of Things and sensor networks face great challenges of low sustainability and limited network capacity.To address the above challenges,the UAV is bound to the Internet of Things system that includes gateways and ground sensors to establish,aerial and ground-integrated Internet of Things network research simulation platforms Through this project,the reliability and sustainability of monitoring sensors are improved,while technologies and applications are proposed for preventing environmental and geological disasters via,predicting and judging climate changes and corresponding consequences.Hence,this project has important social significance for reducing catastrophic consequences.First of all,this paper proposes a task-based approach to promote the simulation process.It establishes a prototype system of the platform according to the requirements of the simulation task.This paper provides the simulation environment and simulation members involved in the task process,then establishes a clear simulation execution process,which puts forward the overall design scheme of the infrastructure and simulation platform of the air-ground integrated,and explains the composition and function of the system.Secondly,this paper establishes a simulation 3D model library based on the design scheme of the air-ground integrated network simulation platform.3Ds Max and other software are used to realize the environmental model of the terrain,base station and other simulation processes,and the simulation 3D modeling of simulation members such as drones and sensor nodes.The three-dimensional model of simulation elements is realized through multiple methods of three-dimensional structure construction,image data,texture map production and model optimization processing.Finally,this paper develops a 3D visual simulation platform for an air-ground integrated network based on Unity3 D.According to the simulation target and execution process,this paper implements the required terrain and other environmental models in the basic simulation settings,the simulation member models,and the dynamic interaction between the simulation models.To fulfill the simulation requirements,which involve the high data collection efficiency under dynamic networking,improved data the safety,and protecting the data integrity during UAV data collection tasks,this paper analyzes the constraints of UAV flight path from the aspects of UAV flight environment and mission objectives,then proposes a strategic model of UAV flight process. |
