Problems solved by technology

Among them, the ROV needs to be tied with an umbilical cable, which limits its underwater movement range. Its open-frame cubic appearance determines that the ROV needs to withstand greater resistance during the process of advancing and diving; Although the appearance of the long body can ensure a small frontal area, it also leads to a large radius of gyration, which has its inherent disadvantages in low-speed maneuverability; due to the characteristics of the Glider without propellers and other driving devices, Although it can guarantee its good battery life, its navigation speed is slow, and it can only sail in zigzag and spiral orbits underwater, and its control performance is poor.
The above three underwater mobile detection platforms can only float in the water, and cannot meet the needs of long-term detection work on the bottom of the water.
In addition, although crawler robots can meet the needs of underwater operations, their movement is only driven by crawlers and their supporting structures, which puts forward higher requirements for the terrain of the working area, especially in areas with large seabed fluctuations. , this disadvantage is becoming more and more prominent
Moreover, crawler robots can only operate in the underwater area, and cannot take into account the relevant detection work in the water, which affects their economy and applicability
After reviewing the information, it is found that there is currently no underwater mobile detection platform that can integrate the underwater and underwater mixed detection modes. And underwater detection work, with good control performance, and has a larger operating range than the aforementioned various underwater mobile detection platforms, and has higher cost performance and other advantages

Description

technical field [0001] The invention relates to the technical field of marine robots, in particular to a benthic-floating hybrid underwater mobile detection platform and a detection method thereof. Background technique [0002] At present, the mainstream underwater mobile detection platforms mainly include remotely operated unmanned submersibles (ROV), autonomous unmanned submersibles (AUV), and underwater glider (Glider). Among them, the ROV needs to be tied with an umbilical cable, which limits its underwater movement range. Its open-frame cubic appearance determines that the ROV needs to withstand greater resistance during the process of advancing and diving; Although the appearance of the long body can ensure a small frontal area, it also leads to a large radius of gyration, which has its inherent disadvantages in low-speed maneuverability; due to the characteristics of the Glider without propellers and other driving devices, Although it can guarantee its good endurance...
