Problems solved by technology

Since underwater robots, underwater glider and other equipment have extremely high requirements on the power consumption, size and weight of the sensor, in order to reduce energy consumption, it is necessary not to damage the streamline shape of the equipment surface as much as possible, and the existing underwater underwater odometer cannot be surface-mounted.

Description

technical field [0001] The invention relates to the field of flow field sensors, in particular to a permanent magnet surface flow field sensor and a sensor array. Background technique [0002] As an important component of underwater equipment such as underwater robots, underwater vehicles, and underwater glider, sensors directly determine the performance of underwater equipment. Unlike land or air equipment, underwater speed measurement has always been a relatively complicated task. process. Since navigation systems such as GPS / GNASS / Beidou cannot be used, and radio navigation methods cannot be used, the navigation and guidance of existing underwater equipment rely on heavy inertial guidance components and magnetic compass and other devices; Navigation and guidance of underwater equipment play an important role. Since underwater robots, underwater glider and other equipment have extremely high requirements on the power consumption, size and weight of the sensor, in order t...
