Embodiment Construction

[0028] Based on the HLA high-level architecture, the distributed interconnection between various system modules in the multi-UAV simulation environment is realized, and the interactive operation between various simulation applications is realized through the federal runtime structure RTI, which makes the whole system scalable. It uses Ethernet UDP to communicate, uses the layered simulation structure combining soft real-time simulation and hard real-time simulation, coordinates the synchronization of the system, and reduces the impact of HLA time performance on system integration. The multi-UAV distributed simulation platform of the present invention can be set for different tasks, such as formation flight, multi-machine cooperative tracking, area coverage, etc., to complete the deduction and simulation of multi-UAV task control and execution process, intuitive performance The simulation process of multiple UAVs. At the same time, the distributed-based design has excellent sca...

Abstract

The invention relates to a multi-unmmaned aerial vehicle distributed simulation method, aiming at providing a distributed simulation platform which can be used for coordination control of a multi-unmmaned system, so as to provide a simulation analysis environment for related theoretical researches on multi-unmmaned aerial vehicle system control schemes and algorithms and improve research efficiency of a multi-unmmaned aerial vehicle algorithm. The invention adopts the technical scheme that an HLA (High Level Architecture)-based multi-unmmaned aerial vehicle distributed simulation method is realized by virtue of a ground control system computer, a platform task management system computer and a plurality of virtual unmmaned aerial vehicle computers, a task scheduler and a corresponding control instruction are sent to the platform task management system computer by virtue of an RTI (Real-Time Interface) simulation interface on the ground control system computer; a decision instruction isproduced on the platform task management system computer aiming at contents of the task scheduler and the control instruction according to a multi-vehicle and single-vehicle control algorithm; and finally real-time flying states of multiple unmanned aerial vehicles are observed in a visualized environment on the virtual unmanned aerial vehicle computers. The multi-unmmaned aerial vehicle distributed simulation method provided by the invention is mainly applied to distributed simulation of the unmmaned aerial vehicles.

Description

technical field [0001] The invention relates to a multi-unmanned aerial vehicle distributed simulation platform problem. Specifically, it is the construction of a multi-unmanned helicopter distributed simulation platform based on HLA. Background technique [0002] The unmanned helicopter has the characteristics of compact structure and flexible movement, which is the best choice for performing boring, harsh or dangerous tasks. However, in actual situations, due to the complexity of the environment and the diversity of tasks, it is difficult for a single unmanned helicopter to complete the planning task, and multiple unmanned helicopters are required to cooperate. It can not only improve the probability of task completion, but also ensure the accuracy of information obtained and maintain the robustness of performing actual tasks. Unmanned helicopters have broad development prospects in many aspects, such as geodesy, meteorological observation, urban environmental monitoring...
