Medium-sized modular autonomous underwater vehicle (AUV)

Abstract

The invention provides a medium-sized modular autonomous underwater vehicle (AUV). Underwater robots are defined as the application target of the medium-sized modular AUV. Modules can be increased ordecreased at random according to the requirements; the wireless communication function is achieved, and wireless on-line programming is supported; an AUV main carrier is designed to be the streamline-shape longitudinal section, and a stern is designed in the mode that four propellers are uniformly distributed, and the four propellers conduct combined control; a bow module is provided with wall touching sonar and a rope-throwing device; an inertial navigation system, a Doppler flow speed meter and a positioning system are matched for use; and a throwing-loading system is mounted under a main control module. The medium-sized modular AUV has the beneficial effects that the advantages that the different modules can be quickly recombined, mounting is convenient, performance is reliable, the navigational resistance is small, and design is reasonable can be achieved, the AUV is conveniently and quickly recycled, and thus the standardization and marketization of the medium-sized AUV become possible.

Description

technical field [0001] The invention relates to the field of underwater robots, in particular to a medium-sized modular AUV. technical background [0002] With the continuous deepening of human understanding of the ocean and the continuous expansion of the scope of exploration, the requirements for AUVs are also increasing, but large and ultra-large AUVs need suitable operating devices to ensure storage, launch and recovery on the offshore mother platform , not only the structure is complicated, the cost is high, but also the operation and maintenance personnel are put forward high requirements. Medium sized AUVs can take on the most missions. Although the small AUV has the characteristics of small size, low cost, flexible navigation, and convenient use, it is limited by the space size, and it is difficult to carry basic sensors such as Doppler current meter and inertial navigation, and the functions that can be realized are limited. The navigation accuracy is insufficient...

Problems solved by technology

Although the small AUV has the characteristics of small size, low cost, flexible navigation, and convenient use, it is limited by the space size, and it is difficult to carry basic sensors such as Doppler current meter and inertial navigation, and the functions that can be realized are limited. Navigation accuracy is insufficient, therefore, researching a medium-sized modular AUV is one of the important issues in the field of underwater robot technology

[0003] At present, domestic medium-sized AUVs mostly adopt an integrated structure, and it is difficult to disassemble and reassemble. Therefore, the establishment of standards and interface specifications is of great significance for improving product competitiveness, reducing life cycle costs, improving unmanned system capabilities, and achieving interoperability on the battlefield. A Practical Mid-Size Modular AUV Became One of the Major Issues for Technology Breakthrough
