Problems solved by technology

[0003] Existing methods can find information such as the geographical location, course speed and other information of merchant ships intending to enter the port at a relatively long distance, but the nature of the cargo carried requires the use of drones to conduct close-in search

Embodiment

[0086] This embodiment takes the search of merchant ships by UAVs in port sealing and control tasks as an example to illustrate the multi-UAV collaborative search path planning method for key target sealing and control disclosed by the present invention, but the present invention can also be applied to other key target sealing In control tasks, such as in the sealing and control of key buildings, the recognition and search of passing vehicles by drones, etc., the present invention does not limit this. The present invention uses unmanned aerial vehicles as the intercepting force, but the present invention can also use other intercepting forces such as airplanes, missiles, etc. for key target sealing and control tasks, and the present invention is not limited to this. In the port sealing task, this embodiment makes the following assumptions:

[0087] 1) Assume that all the merchant ships sailing to the port point to the center of the circle, the merchant ships move forward at a ...

Abstract

The invention discloses a multi-UAV cooperative search path planning method in key target sealing and control. The method includes the steps of: determining constraint conditions, constructing a UAV identification task assignment model; determining the encounter time between the UAV and the key target; key target data Preprocessing; initial chromosome gene information is obtained by clustering; the total flight time of the drone is calculated, and the corresponding fitness of the chromosome is calculated; inheritance, mutation and crossover are carried out according to the fitness of chromosomes in various groups; it is judged whether the genetic algebra is reached; the population is selected The best offspring of the genes that appeared in the genetic process are used as the result corresponding to the task sequence. The invention establishes a fast solution method for the encounter time between the UAV and the merchant ship through the transformation of the coordinate system, adopts Kmeans clustering to generate the initial population, greatly improves the feasibility of the initial solution, and adds local search in the mutation operation to ensure the diversity of the mutation , give the minimum number of drones and a reasonable disposal plan.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a multi-unmanned aerial vehicle cooperative search path planning method in key target sealing and control. Background technique [0002] Ensuring the safety of important targets and preventing emergencies are the primary duties and main tasks of the units and personnel involved in the containment task. Taking port sealing as an example, the key targets are merchant ships entering the port, which are roughly divided into three categories, namely, merchant ships transporting general daily necessities, merchant ships transporting major strategic materials such as oil or natural gas, and merchant ships transporting contraband such as weapons and equipment. . [0003] Existing means can find information such as the geographic location, course speed, and other information of merchant ships intending to enter the port at a relatively long distance, but the ...
