Embodiment Construction

[0064] The present invention is further described below with reference to the accompanying drawings in conjunction with specific embodiments.

[0065] It should be noted that components in the various figures may be shown exaggerated for illustration purposes and not necessarily to correct scale. In the various figures, identical or functionally identical components are provided with the same reference numerals.

[0066] In the present invention, unless otherwise specified, "arranged on", "arranged over" and "arranged over" do not exclude the case where there is an intermediate between the two. In addition, "arranged on or above" only means the relative positional relationship between two components, and in certain circumstances, such as after reversing the product direction, it can also be converted to "arranged under or below", and vice versa Of course.

[0067] In the present invention, each embodiment is only intended to illustrate the solution of the present invention, ...

Abstract

The invention provides an unmanned ship cluster distributed safety control method, which comprises the following steps: carrying out association modeling on a wave disturbance model, a composite fault model and a DoS attack model of an unmanned ship cluster system to form a comprehensive model; establishing a non-periodic DoS attack model of the unmanned ship cluster according to the comprehensive model; and according to DoS attack activation and dormancy stages divided by the non-periodic DoS attack model, enabling the unmanned ship cluster to implement switching between baseline control and distributed security control, and performing unmanned ship cluster updatable control based on event triggering in the DoS attack dormancy stage.

Description

technical field [0001] The invention relates to the technical field of unmanned boats, in particular to a distributed safety control method for unmanned boat swarms. Background technique [0002] In recent years, with the depletion of terrestrial fuel resources, the strategic position of the ocean, which occupies about 71% of the earth's area, has been continuously improved. In order to fully explore and exploit marine resources, the development of marine equipment technology is indispensable. Marine intelligent equipment represented by unmanned boats (including underwater vehicles, underwater robots, surface unmanned ships, etc.) is the main carrier of marine operations at this stage. [0003] The working range of unmanned boats is often in waters with complex and changeable environments, which often brings unpredictable effects to unmanned boats. With the improvement of the operational capability of the unmanned boat, its complexity has also increased, and its security h...
