Secondary automatic barrier avoiding system and method of unmanned boat in high-speed state

Abstract

The invention discloses a secondary automatic barrier avoiding system and method of an unmanned boat in a high-speed state, and provides an embedded engineering control machine and a hull control module which are arranged on the unmanned boat of AIS equipment, a microwave radar, a millimeter wave radar, a laser radar and an unmanned boat body. The method comprises the steps that barrier objects inlong and short distance are detected by using the AIS equipment, the microwave radar, the millimeter wave radar and the laser radar, and different barrier avoiding selections are adopted in the method. The method and the system have the advantages that the additional consumption of the unmanned boat brought by barrier avoiding can be reduced under the premise that the safety moving of the unmanned boat is achieved, and therefore the effective speed and range of the unmanned boat are effectively improved, and the effect is significant.

Description

technical field [0001] The invention relates to the technical field of unmanned boats, in particular to an obstacle avoidance system for an unmanned boat, in particular to a secondary autonomous obstacle avoidance system for an unmanned boat at high speed. Background technique [0002] In recent years, with the continuous development of unmanned equipment technology, unmanned boats, as unmanned equipment mainly used for surface work, have also achieved a high degree of research. Domestic and foreign companies and scientific research institutions have successively developed many types of unmanned boats. to meet various demands. Common unmanned boats are mostly used for water quality monitoring, seabed surveying and mapping, and detection of buried objects on the seabed. The speed requirements for unmanned boats are not high, but high-speed unmanned boats are required to complete corresponding tasks in areas such as sea surface patrol and suspicious ship follow. For unmanned ...

AI Technical Summary

Problems solved by technology

[0003] Traditional unmanned boats generally use laser and other equipment to avoid obstacles. When obstacles are detected, the original route is abandoned and re-planned, bypassing obstacles to continue forward. However, due to the high speed of high-speed unmanned boats, laser sensors monitor obstacles The effective distance is relatively short. If the traditional solution is adopted, when the laser sensor detects an obstacle, it is already difficult to avoid the obstacle, which is likely to cause accidents and bring danger.
