Abstract

The invention relates to the technical field of submarine mining, in particular to a high-precision networked navigation system for submarine mining, which comprises at least one water surface navigation platform, mine car pilots with the same number as mining cars, pilot positioning terminals and umbilical cables, the water surface navigation platform comprises a wave glider body, a satellite positioning device and an underwater acoustic navigation node, wherein the satellite positioning device and the underwater acoustic navigation node are arranged on the wave glider body. And the mine car navigator is provided with an underwater acoustic positioning terminal, an inertial assembly, a navigator positioning node, an optical scanner, a high-frequency imaging sonar, a Doppler log, an obstacle avoidance sonar and an underwater vehicle platform. According to the invention, all-weather and all-time seabed mining navigation service can be realized.

Description

Technical field [0001] The present invention relates to the field of submarine mining technology, and the specific field is a high-precision network navigation system for subsea mining. Background technique [0002] At present, deep sea mineral resources mining is in key technical research, the core equipment R & D verification stage, commercial mining top design plan is still in progress in the planning argument, systematic production efficiency, reliability, economy, etc. have not yet been carried out in-depth study. [0003] The positioning of the previous underwater mining equipment mainly relies on the water sound positioning, the inertial component, and the Doppler measters in combination. The CN109655056A uses this type, and the six passive sonas arranged by fixed arrangement is active on the mining vehicle. The phonochi is constituted a water sound positioning system, providing three-dimensional absolute positioning, and provides real-time positions through the inertial s...
