Autonomous collision-preventing device for underwater AUV /UUV (Autonomous Underwater Vehicle/Unmanned Underwater Vehicle) platform

Abstract

The invention aims at providing an autonomous collision-preventing device for an underwater AUV / UUV (Autonomous Underwater Vehicle / Unmanned Underwater Vehicle) platform, which comprises a casing, a horizontal transducer array, a vertical upward transducer, a vertical downward transducer, an underwater acoustic signal conditioning unit, a transmitting unit, an underwater acoustic signal processing unit, an input / output interface unit, a pressure sensor and a battery pack, wherein the horizontal transducer array is arranged at the front end in the casing; the vertical upward transducer and the vertical downward transducer are respectively arranged above and below the casing; and the transmitting unit, the underwater acoustic signal conditioning unit, the underwater acoustic signal processing unit, the input / output interface unit, the pressure sensor and the battery pack are respectively arranged in the casing. The autonomous collision-preventing device has the advantages of autonomous detection and recognition capability, capability of outputting specific position and distance information of an obstacle, easiness in installation and operation, high precision, high reliability and wide application range.

Description

technical field [0001] The invention relates to a device for underwater device detection and collision avoidance. Background technique [0002] The 21st century is the century in which mankind marches to the ocean. As one of the untapped treasures and high-tech fields of human beings, the deep sea has become an important strategic goal of various countries, and it is also one of the focuses of fierce international competition in recent years. As a high-tech means, the importance of underwater robots in the field of ocean development and utilization is no less than the role of spacecraft and rockets in exploring space. An underwater robot is a special detection system with vision and perception functions underwater. It uses some auxiliary detection tools to replace human beings to complete some underwater tasks through various operation methods. Autonomous submersibles" (AUV or UUV). When AUV performs various missions, it can carry out global path planning based on the ele...

AI Technical Summary

Problems solved by technology

Although the collision avoidance equipment imported from abroad has the advantages of small size and high resolution, the output is the image information of obstacles, and its autonomy is relatively poor. It needs to be further processed by the AUV platform to extract useful information to guide the action of the AUV. and judgment ability put forward higher requirements
