Description

technical field [0001] The invention relates to the field of surge current detection, in particular to a dot-matrix surge current detection system, which is used for online detection of surge current in an underwater application environment. Background technique [0002] Underwater robots have achieved great practical application results in underwater environment detection, monitoring, underwater target capture, and underwater facility operations. It can quickly and efficiently complete related measurement, monitoring, monitoring and manipulator actions. When the underwater robot encounters the interference of the surge during the operation, it will cause problems such as sway, heave, roll, and pitch instability. How to effectively realize the three-dimensional detection of surge information and provide reference and experiments for the control of underwater robots has become a research direction in this field. [0003] At present, the surge current simulation system mainl...
