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

Embodiment Construction

[0022] The invention provides a medium-sized modular AUV, which adopts the concept of modular design, can increase or decrease modules arbitrarily according to requirements, has wireless communication function, and supports wireless online programming. To reduce sailing resistance, the design of the stern adopts the method of four propellers evenly distributed. Through the joint control of the four propellers, the maneuverability is increased and the complexity of the driving mechanism is reduced. Early warning of obstacle collisions during the process improves system safety, and a rope thrower is installed to facilitate AUV recovery after the mission is over. The inertial navigation system, Doppler current meter and positioning system are used together to improve navigation accuracy. The loading system is installed directly under the main control module, the AUV performance is safe and reliable, and the modular design of the medium-sized AUV is realized, making the standardiza...

Abstract

The invention provides a medium-sized modularized AUV, and the application target is positioned as an underwater robot. Modules can be added or removed arbitrarily according to requirements, with wireless communication function, and wireless online programming is supported. The main carrier of AUV is designed as a streamlined longitudinal section, and the stern is designed with four propellers evenly distributed, through the joint control of four propellers , the bow module is equipped with a wall impact sonar and a rope thrower, the inertial navigation system, the Doppler current meter and the positioning system are used together, and the dumping system is installed directly below the main control module. The beneficial effects of the present invention are: different The advantages of fast module reorganization, convenient installation, reliable performance, low navigation resistance, and reasonable design realize the convenient recovery of AUVs and make the standardization and marketization of medium-sized AUVs 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...
