Abstract

The invention discloses an autonomous navigation system of a miniature underwater detection robot, belonging to the technical field of AUV underwater navigation, comprising: a first processor; Scan underwater objects for collision avoidance during navigation; magnetometer, used to obtain magnetic field strength and direction; inertial measurement unit, used to obtain three-axis attitude angle, angular rate and acceleration; data recorder, used to sense obstacle avoidance sonar The unit, magnetometer, and inertial measurement unit acquire and store the measurement results; the analog-to-digital converter is used to convert the analog signal into a digital signal; the input and output module is used to input and output data; the autonomous navigation system of the miniature underwater detection robot, It does not rely on external sensors, does not need to arrange acoustic communication positioning nodes, and does not need to surface to combine GNSS signals to achieve long-term, independent, and autonomous underwater navigation.

Description

technical field [0001] The invention belongs to the technical field of AUV underwater navigation, in particular to an autonomous navigation system of a miniature underwater detection robot. Background technique [0002] In recent years, AUV underwater navigation has become the focus and difficulty in the development of underwater positioning technology. After in-depth research by scholars from various countries, initial results have been achieved. Researchers have conducted in-depth research on AUV autonomous navigation and developed a variety of underwater navigation and positioning technologies, mainly including: Inertial Navigation System (INS), Global Navigation Satellite System (GNSS), acoustic positioning System (Acoustic Positioning System, APS), Doppler Velocity Log (DVL), geophysical navigation, these navigation devices have their own advantages and disadvantages; [0003] 1. Inertial navigation, no external equipment is required, and errors accumulate over time; ...
