Abstract

The invention discloses an ultrasonic underwater detection method for an unmanned spaceship cooperatively driven by aerial rotors and propellers, and the ultrasonic underwater detection method for theunmanned spaceship cooperatively driven by the aerial rotors and the propellers moves and balances the unmanned spaceship by controlling the aerial rotors above the unmanned spaceship and the underwater propellers below the tail part of the unmanned spaceship. The method comprises the following steps: receiving a control command to obtain a detection fixed-point position; flying to a detection fixed point; measuring and recording the attitude of the unmanned spaceship by using an attitude instrument, and counting the wave motion direction; controlling the unmanned spaceship to face the direction perpendicular to the wave motion direction; controlling the unmanned airship to sail around the detection fixed point; controlling the ultrasonic microarray to collect water area parameters; keeping the posture of the unmanned spacecraft; if scanning detection needs to be carried out, changing and detecting the rolling angle and the yaw angle of the unmanned spaceship; and if the fixed-point water area detection is completed, receiving a control command and flying to the next detection fixed point, otherwise, continuing navigation detection. According to the invention, the detection speedand the detection precision of the unmanned spaceship can be improved.

Description

technical field [0001] The invention mainly relates to the field of unmanned water area detection, in particular to an ultrasonic underwater detection method for an unmanned spaceship driven by an aerial rotor and a propeller. Background technique [0002] An unmanned ship is a fully automatic surface robot that can sail on the water surface according to preset tasks with the help of precise satellite positioning and self-sensing without remote control. The English name is unmanned surface vessel, and the English abbreviation is USV. Unmanned ships are mostly used for Surveying, hydrology and water quality monitoring. Replacing manpower with unmanned ships can greatly reduce manpower and improve efficiency. In the past detection missions, the detection personnel need to carry their own detection equipment and carry boats to the detection location for water detection. During the detection process, the boat may run aground. , water pollution, bad weather and other conditions ...
